Dongguan's plastic mold industry introduces 3D printing technology on a large scale

As an emerging technology, 3D printing has become a powerful tool for linking intelligent manufacturing. A few days ago, the Dongguan Municipal Bureau of Economy and Information Technology and the Dongguan Electronic Information Industry Association jointly organized a smart talent training event. At the event site, Dongguan Plastic Mould Company News released an industrial-grade 3D printer to serve Dongguan plastic mould enterprises.

 

Improve cooling efficiency and shorten casting cycle

 

"By analyzing the hot spots of the mold map provided by the customer, after finding the corresponding area that inhibits the mold cooling efficiency, the conformal waterway scheme is designed. After the customer confirms the design scheme, the layered software and production machine are imported. It is ready to 3D print plastic molds. This is the practical process of mass production of molds using 3D printing technology.

 

Compared with traditional production, the model efficiency and yield rate of using 3D printing technology to die machining are higher. Because the production of molds needs to be in special environments such as high temperatures, this has led to the phenomenon of uneven heating and high defect rates in traditional processing modes; now 3D printing technology is applied, and mold production can be evenly heated in all positions , Which directly improves the yield of products.

 

It is worth noting that the application of 3D printing technology can also shorten the cycle of mold molding. According to the traditional production model, only 100 molds can be produced in one hour; with 3D printing technology, the number of molds produced in one hour can reach as many as 1,000.

 

Using 3D printing technology, a 3D conformal waterway can be made inside the mold, which greatly improves the cooling efficiency and shortens the titanium investment casting cycle, which not only saves costs, but also improves the quality of products and enhances the competitiveness of enterprises. At present, this technology has been widely used in the stand casting mold industry in Europe, America and Japan.

 

According to the person in charge of the company, the customer requires a plastic machining cycle of 25s. Because the temperature of the PC material is relatively high, the cooling water path must be sufficient and uniform. 3D printing technology can perfectly solve this problem.

 

3D printing technology has a promising future

 

With the continuous development of 3D printing technology, it has been widely used in industrial vertical fields, so industrial applications will be the largest component of the cheap 3D printing market share.

 

As an international manufacturing city, Dongguan is driven by the continuous and rapid development of IT industry, precision machinery and other industries, and a number of hardware mold companies have emerged. Chang'an, Hengli and other places have also become important towns in the hardware mold industry in Dongguan. Relevant statistics show that every 100 million yuan in the mold industry can drive the development of about 10 billion yuan in related industries.

 

The combination of molds and 3D printing plans will have unexpected chemical reactions. One is an indispensable tool in modern industry, and the other is high-tech. The integration of the two will bring a qualitative leap for Dongguan's industry.

 

Dongguan is the main gathering place for the mold industry. Since the beginning of this year, more and more companies have started to launch 3D printing equipment. If 3D printing equipment is applied on a large scale in the future, it will subvert the production mode of Dongguan mold industry.

Speed ​​regulation method of CNC lathe machining spindle

In order to meet the requirements of the main drive of CNC lathe processing, CNC machine tools (attribute: automated machine tools) often use a motor stepless speed regulation system. The method of combining multi-level speed regulation realizes spindle speed regulation. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and letters, and the processing required by the processing technology. It generally refers to the process of processing parts on CNC machine tools. In order to improve the degree of production automation, shorten the programming time and reduce the cost of CNC machining, a series of advanced CNC Swiss machining technologies have been developed and used in the aerospace industry.

 

1. Mechanical gear shift

 

In the main transmission system of CNC lathe processing, the traditional spindle box structure is greatly simplified due to the stepless speed regulation of the electric motor. However, due to the limitation of the spindle motor and the driving power supply, the output of constant torque is often in its low speed range. In order to enable the spindle to provide the maximum output power of the main motor within the entire speed range as much as possible, and to meet the needs of CNC machine tools (attributes: automated machine tools) for low-speed and powerful cutting, a combination of 1 to 4 gear speeds and stepless speed regulation is often used The method is the so-called stepless speed regulation in sections. The use of mechanical gearbox housing gear deceleration not only amplifies the output power, but also expands the range of speed regulation.

 

When CNC lathe processing is cutting, the spindle runs automotive parts at the speed specified by the S command in the part processing program. Therefore, there must be two types of spindle speed command signals in the numerical control system, that is, analog (definition: virtual of real things or processes) or digital signal S code to control the drive speed regulation circuit of the spindle motor, and at the same time use the switch signal (M code) to control the actuator of mechanical gear shifting and automatic shifting. The automatic shifting actuator is an electric-mechanical conversion device, commonly used hydraulic shift forks and electromagnetic clutches.

 

2. Motor speed regulation

 

The speed-regulating motors used for the spindle drive of CNC lathes are mainly divided into two categories: DC and AC.

 

(1) DC motor speed regulation-usually Axis CNC tools have a large speed regulation range, and the DC motor speed regulation adopts both voltage regulation and magnetic regulation. The characteristic curve of its typical DC spindle motor is shown in Figure 61. It can be seen from its characteristic curve that the motor below the speed n0 belongs to constant torque speed regulation, that is, it is realized by changing the armature voltage; above the speed n0, it belongs to the constant power (referring to the work done by the object in a unit of time). How much) Speed ​​regulation is achieved by changing the excitation current.

 

The more commonly used FANUC DC-excited spindle motor uses a three-phase fully-controlled thyristor (zhá) tube non-circulating current reversible speed regulation system, which can realize voltage and magnetic speed regulation, and the speed range is 35. ?~3500r/min. CNC electronics machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough stainless steel machining and idle stroke.

 

(2) AC motor speed regulation

 

At present, cage induction motors are used in AC main shaft drives of CNC machine tools, and vector control frequency conversion speed regulation methods are widely used.

With the improvement of new DC and AC spindle speed control motors, motor speed control will be widely used. However, in order to reduce costs in economical CNC machine tool steel

 (attributes: automated machine tools), mechanical gear shifting methods are often used. Change the spindle speed. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and letters, and the processing required by the processing technology. It generally refers to the process of processing Iron parts on CNC machine tools. In order to improve the degree of production automation, shorten the programming time and reduce the cost of CNC steel machining, a series of advanced CNC machining technologies have been developed and used in the aerospace industry.

Advantages of CNC machine tool processing

CNC machine tool (attribute: automatic machine tool) processing is a high-precision, high-efficiency automatic machine tool. The use of CNC machine tool processing can improve processing efficiency, create more value, and get rid of the backward processing technology. The processing technology of ordinary lathes is similar. What are the advantages of CNC machining?

 

1. High productivity

 

CNC machine tools can effectively reduce the processing time and auxiliary time of the parts. The spindle speed and feed range of the CNC coffee machine parts tools are large, allowing the machine tools to carry out powerful cutting with large amounts of cutting, the rapid movement and positioning of the moving parts of the CNC machine tools and high-speed cutting processing. , It reduces the turnaround time between processes of semi-finished products and improves production efficiency.

 

2. High processing accuracy

 

The machining accuracy (precision) of CNC machine tools can generally reach 0.0050.1mm. CNC machine tools are controlled in the form of digital signals. Each time the CNC device outputs a pulse signal, the moving parts of the machine tool move by one pulse equivalent (generally 0.001mm) , And the average error of the backlash of the machine tool's feed drive chain and the lead screw pitch can be compensated by the numerical control device. Therefore, the numerical control machine tool has a relatively high positioning accuracy. CNC machining CNC is also called computer gong, CNCCH or numerical control machine tool. It is actually a kind of name in Hong Kong, which greatly reduces the number of tooling. CNC machining parts with complex shapes does not require complex tooling. CNC machining is a new type of processing technology, the main work It is to compile the processing program, that is, to convert the original manual work to computer programming. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.

 

3. Highly flexible

To ensure the surface accuracy (accuracy) of the workpiece, it mainly depends on the processing procedure. It is different from the ordinary machine tool. There is no need to manufacture and replace many tools and fixtures, and there is no need to adjust the machine tool frequently. CNC machining General CNC iot machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. Therefore,  Stainlesss teel parts tools are suitable for occasions where parts are frequently replaced. That is, it is suitable for single piece, small batch production and the development of new products, shortens the production preparation cycle, and saves a lot of process equipment costs.

 

4. The processing quality is stable and reliable

 

To process the same batch of parts, on the same machine tool, under the same processing conditions, using the same tool and processing procedure, the cutting path of the tool is exactly the same, the consistency of the masks machine parts is good, and the quality is stable (explanation: stable and stable; no change).

 

5. Conducive to modernization of production management

 

CNC machine tools (attributes: automated machine tools) can accurately estimate the other processing time in advance, and the tools and fixtures used can be standardized and modernized. Numerical control machine tools use digital signals and standard codes as control information, which is easy to realize the standardization of processing information. At present, it has been organically combined with computer-aided design and manufacturing (CAD/CAM), which is the basis of modern integrated manufacturing technology.

 

6. Improve working conditions

 

After the CNC machine tool (attribute: automatic machine tool) is adjusted before processing, enter the program and start it, and the machine tool can automatically and continuously process until the end of the processing. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and letters, and the processing required by the processing technology. It generally refers to the process of machinery parts on CNC machine tools.

 

In order to improve the degree of production automation, shorten the programming time and reduce the cost of CNC machining, a series of advanced CNC machining technologies have been developed and used in the aerospace industry. Operators are mainly engaged in program input, editing, loading and unloading of masks-machine-parts, tool preparation, observation of aluminum machining status, and parts inspection. The labor intensity is greatly reduced, and the labor of machine tool operators tends to be intellectual work. In addition, the machine tool is generally closed processing, which is clean and safe.

LCD (Liquid Crystal DisplayLiquid Crystal Display. The structure of LCD is to place a Liquid Crystal cell between two parallel Glass substrates. The lower substrate Glass is equipped with TFT (thin film Transistor), and the upper substrate Glass is equipped with a color filter. The signal and voltage on the TFT are changed to control the liquid crystal molecules. Rotate the direction, so as to achieve the display purpose by controlling whether the polarized light of each pixel point is emitted or not. LCD has replaced CRT as the mainstream, and the price has dropped a lot, and it has been fully popularized.
A few days ago, according to data from CINNO Research, 2020 is expected to be the first year of mass production and launch of fingerprint recognition mobile phones under the LCD screen.

LCD Type
According to the different Backlight sources, LCDs can be divided into two types: CCFL displays and LED displays.
Misunderstanding:
Many users believe that liquid crystal displays can be divided into LEDs and LCDs. To some extent, this understanding is misguided by advertisements.

LCD

The LED display on the market is not a true LED display. To be precise, it is an LED-backlit liquid crystal display. The liquid crystal panel is still a traditional LCD display. In a sense, this is somewhat fraudulent. nature! South Korea's Samsung was once convicted by the British Advertising Association as violating the country's advertising laws because its "LED TV" LCD TVs were suspected of misleading consumers. For liquid crystal displays, the most important key is the type of liquid crystal panel and Backlight, while the liquid crystal panels of displays on the market generally use TFT panels, which are the same. The difference between LED and LCD is only their Backlight type: LED The backlight and CCFL backlight (that is, fluorescent lamps) are Diodes and cold cathode lamps, respectively.

LCD is the acronym for Liquid Crystal Display, which means "liquid crystal display", that is, liquid crystal display. The LED display refers to a type of liquid crystal display (LCD), that is, a liquid crystal display (LCD) with LED (light emitting Diode) as the backlight source. It can be seen that LCD includes LEDs. Corresponding to the LED display is actually a CCFL display.

Factors affecting the price of beryllium copper

International economic situation. The correlation between the commodity market and the economic situation is obvious, especially as the world economy is becoming increasingly globalized, and the commodity market and the economy are more related. Therefore, the price of beryllium copper is closely related to the economic situation.

 

The consumption of beryllium copper is mainly concentrated in developed industrial countries. The economic conditions of these countries such as the United States, Japan, Western Europe and other countries have a greater impact on the price of beryllium copper. Generally speaking, the economic situation is good, the demand for beryllium copper increases, and the price rises, and vice versa decline.

 

   The production status of the producing country. Chile is rich in beryllium copper resources and the world's beryllium copper exporter. Zambia and Zaire in central Africa are also important beryllium copper producing countries. Almost all of the beryllium copper produced by them is used for export. Their production status is important to the international beryllium copper market. great influence. The governance situation in these three countries has always been unstable, and labor disputes have often occurred, which also has a direct impact on the price of beryllium copper.

 

   Seasonal influence. The seasonal fluctuations in the price of beryllium copper are more obvious, with a trough in January and a high price in August. The influence of industry policy.

 

Since copper beryllium is mainly used in electrical, electronic, construction, machinery and transportation industries, the country's industrial policies for these industries have a more important impact on the price of beryllium copper.

 

   The price of the substitute. In the telecommunications industry, beryllium copper has always been an important raw material. However, due to the promotion and application of optical fiber technology, the position of beryllium copper has been challenged. At the same time, aluminum and other metal materials have the same properties as beryllium copper and are also used in most areas of use. Instead of beryllium copper.

 

   The impact of inventory. Inventory is one of the important factors affecting the price of beryllium copper. Under different market conditions, companies will take different measures to increase or decrease inventory. In order to ensure the production of raw materials or speed up the flow of funds, throughput reserves will also be used at different periods to stabilize the beryllium copper market.

 

  The influence of other policies and regulations. Since the beryllium copper machining market is an international market with a large volume of international trade, it is necessary to increase the import and export policies,

 

Changes in factors such as the exchange rate system and the intensity of combating smuggling will also have an impact on the price of beryllium copper.

How to determine the thickness of aluminum alloy die castings?

In the design process of aluminum alloy die castings, many customers are uncertain about the thickness of aluminum alloy die castings, and they do not know how thin the thickness of aluminum alloy die castings can be.

 

1. The aluminum alloy die-cast product wall is also not suitable for too thin, large-scale and too thin walls are prone to defects such as under-casting and cold partition.

 

2. The choice of wall thickness for aluminum alloy die-casting products: under normal conditions, the wall thickness is not suitable to exceed 4.5mm, suitable for small and medium-sized castings: zinc alloy material 1-3mm, aluminum and magnesium alloy 1.5-4mm, alloy copper 2- 4mm.

 

3. The thickness of aluminum alloy die-casting products should be uniform, which is beneficial to the additional condensation of aluminum alloy liquid after "filling". It can prevent the disadvantages of forging ground stress, shrinkage porosity and cracks.

 

4. For the thick-walled pipe part of the aluminum die-casting product variety, ribs or cast inserts can be selected to enhance its physical properties and improve process performance.

 

Therefore, in the thick wall design of aluminum alloy die-casting parts, it is not suitable to choose the method of raising the thickness of the wall to increase the bearing capacity of aluminum die-casting products. When the thickness of the casting exceeds the necessary limit, its impact toughness will decrease accordingly. Excessive thickness of the silicone casting wall will easily cause shrinkage porosity and air vents, and will cause the initial setting of the aluminum alloy die-casting production process to cause long initial setting, large shrinkage, core pulling, difficult demolding and other unfavorable conditions.

 

We focus on aluminum alloy die-casting customization and have many experienced die-casting production teams. We can also provide you with reasonable and effective suggestions during the process of thick wall control of aluminum alloy die-casting parts!
