First, the status quo Since the reform and opening up, with the rapid development of the national economy, the demand for molds in the market has continued to grow. In recent years, the mold industry has been developing rapidly with a growth rate of about 15%. All the manufacturing points of mold industry enterprises have undergone tremendous changes. In addition to the state-owned professional mold factories, collective, joint venture, sole proprietorship and private sector have also developed rapidly. The “hometown of molds†in Ningbo and Huangyan areas of Zhejiang Province; some large group companies in Guangdong and fast-growing township enterprises, Kelon, Midea, Konka and other groups have established their own mold manufacturing centers; Sino-foreign joint ventures and wholly foreign-owned mold companies are now There are already thousands of them. With the accelerating pace of international integration and increasing market competition, people have become increasingly aware of the importance of product quality, cost and ability to develop new products. Mold manufacturing is one of the most basic elements in the entire chain. Mold manufacturing technology has become an important indicator to measure the level of manufacturing in a country, and to a large extent determines the survival space of enterprises. In recent years, many mold companies have increased their investment in technological advancement and regarded technological progress as an important driving force for enterprise development. Some domestic mold companies have popularized two-dimensional CAD, and have begun to use UG, Pro/Engineer, I-DEAS, Euclid-IS and other international software. Some manufacturers have also introduced Moldflow, C-Flow, DYNAFORM, Optris and MAGMASOFT. CAE software has been successfully applied to the design of stamping dies. The manufacturing technology of large-scale stamping dies represented by automobile cover moulds has made great progress. Diemakers such as Dongfeng Motor Company Mould Factory and FAW Mould Center have been able to produce some car cover moulds. In addition, many research institutes and universities have conducted research and development of mold technology. After years of hard work, significant progress has been made in mold CAD/CAE/CAM technology; contributions have been made in improving mold quality and shortening mold design and manufacturing cycles. For example, KMAS software for stamping and forming of automobile panels independently developed by Jilin University Automotive Panel Forming Technology, injection molds, automotive panel molds and progressive die CAD/CAE/CAM software developed by the State Key Laboratory of Mould Technology, Huazhong University of Science and Technology The cold die and fine die CAD software developed by the cold die and fine punch research center developed by Shanghai Jiaotong University Mould CAD National Engineering Research Center have many users in the domestic mold industry. Although China's mold industry has made remarkable progress in the past decade, many aspects still have a large gap compared with industrial developed countries. For example, the proportion of precision processing equipment in mold processing equipment is relatively low; the penetration rate of CAD/CAE/CAM technology is not high; many advanced mold technology applications are not widely used, etc., resulting in a considerable part of large, precise, complex and long life molds. Dependent on imports. Second, the future development trend of stamping die manufacturing technology The development of mold technology should be adapted to the requirements of mold products with short delivery time, high precision, good quality and low price. To meet this requirement, it is urgent to develop the following items: (1) Full promotion of CAD/CAM/CAE technology mold CAD/CAM/CAE technology is the development direction of mold design and manufacture. With the development and advancement of microcomputer software, the conditions for popularizing CAD/CAM/CAE technology have been basically mature, and enterprises will increase the intensity of CAD/CAM technology training and technical services; further expand the application scope of CAE technology. The development of computers and networks is making it possible to promote CAD/CAM/CAE technologies across the region, across enterprises and across campuses, and to achieve re-integration of technical resources to make virtual manufacturing possible. (3) Mold scanning and digitizing system The high-speed scanner and mold scanning system provide many functions required from model or physical scanning to processing the desired model, which greatly shortens the development cycle of the mold. Some fast scanning systems can be quickly installed on existing CNC milling machines and machining centers to achieve fast data acquisition, automatic generation of various CNC system processing programs, CAD data in different formats, and "reverse engineering" for mold manufacturing. ". The mold scanning system has been successfully applied in the automotive, motorcycle, home appliance and other industries, and it is believed that it will play a greater role during the 10th Five-Year Plan period. (4) EDM milling EDM milling technology, also known as EDM creation technology, is a new technology that replaces the traditional processing of the cavity with a shaped electrode. It is a simple tubular electrode with high-speed rotation. 3D or 2D contour machining (like CNC milling) eliminates the need to make complex shaped electrodes, which is clearly a major development in the field of EDM. Machine tools using this technology have been used in mold processing abroad. It is expected that this technology will be developed. (5) Improve the standardization degree of molds The standardization degree of molds in China is constantly improving. It is estimated that the coverage rate of China's mold standard parts has reached 30%. Developed countries in foreign countries generally have about 80%. (6) High-quality materials and advanced surface treatment technology It is necessary to select high-quality steel and apply corresponding surface treatment technology to improve the life of the mold. Whether the heat treatment and surface treatment of the mold can fully utilize the key aspects of the performance of the mold steel material. The development direction of mold heat treatment is vacuum heat treatment. In addition to perfecting the surface treatment of the mold, advanced vapor deposition (TiN, TiC, etc.) and plasma spraying techniques should be developed. (7) Mold grinding and polishing will have a large impact on the quality of the mold surface and the appearance quality of the workpiece. The research automation and intelligent grinding and polishing methods replace the existing manual operation. Improving the surface quality of the mold is an important development trend. (8) Development of automatic mold processing system This is the goal of long-term development in China. The mold automatic processing system should have reasonable combination of multiple machine tools; equipped with accompanying positioning fixtures or positioning discs; complete machine tool and tool CNC library; complete CNC flexible synchronization system; quality monitoring and control system. The development of CNC engraving machine has only been greatly developed in the past one or two years. Relevant processing factories and users have always stared at the trend of manufacturers with a keen eye. This is also the main manufacturer of engraving and milling machine. The real reason for not being able to relax. As a user, of course, we must choose the right equipment. If the selection is not appropriate, not only can we not make money, but it will make us fall into the bitter situation of working for the machine. So what kind of machine tool is a good machine tool? We believe that the definition of a good machine tool is this: A machine tool that can recover the investment in a short period of time is a good machine tool. The design life of CNC machine tools is generally 7 years, mainly based on the service life of CNC. The proportional relationship between spending money and earning money will directly affect your business. Therefore, careful analysis of functions for selection is a necessary condition for effective investment. . The term "CNCengravingandmillingmachine" is very early in foreign countries. Strictly speaking, carving is part of milling. It is a question to ask yourself if you are buying an engraving machine or buying a CNC milling center. In addition, there are currently high-speed cutting machine tools (HSCMACHINE). Let us first figure out the difference between the three models: An in-depth analysis of the structure of the above equipment can help us make the right choice. First, from a mechanical point of view The machine tool is divided into two parts, the moving part and the non-moving part: the work table, the skateboard, the cross flower table, etc. are moving parts, the bed base, the column, etc. are non-moving parts. 1. CNC milling machining center: The non-moving part has very good steel requirements. The moving part has very good steel requirements. It has the advantage of being able to carry out heavy cutting. Disadvantages: Because the moving parts are equally large, the flexibility of the machine is sacrificed, and there is no power for small parts and rapid feed. 2, CNC engraving and milling machine The non-moving part of the steel requires a good moving part of the steel to be flexible, as light as possible, while maintaining a certain degree of rigidity. Advantages: It can carry out relatively small processing and has high processing precision. High-speed machining for soft metals; Disadvantages: Heavy cutting is not possible due to poor steel properties. 3. High-speed cutting machine The non-moving part requires very good steel properties. The moving part has better steel requirements and is as light as possible. Advantages: It can carry out small and medium-sized cutting (for example, a flat-bottom knives of φ10, and a depth of 0.75 for 45 steel (300) is good); Disadvantages: It can be used efficiently and at low cost under proper use, so that the amount of grinding is extremely small. Improper use will immediately make the scrap of the tool pile up. How to do the above requirements from the mechanical, light, rigid and contradictory, the key lies in the mechanical structure. 1. The bed body adopts a mesh structure with high and low ribs, and some directly adopt the hexagonal mesh structure of the honeycomb, the ultra-wide column and the beam. We know that the gantry structure is excellent in its symmetry and Excellent steel is always the preferred structure for high speed cutting equipment manufacturers. 3. The difference between the moving part and the numerical control milling is that the distance between the guide rail and the guide rail is widened to overcome the problem of bad torque. 4. In terms of materials, it is generally used in Mehana cast iron, which is to inoculate cast iron. When casting molten iron, a certain proportion of silicon (Si) is added to change the internal structure of iron, making it more resistant to stamping and significantly improving rigidity. . 5. The rigidity of the machine tool is mainly used to overcome the strong impact of the moving part on the non-moving part when moving at high speed, so the guide rail and the screw rod are required to be thicker, and the rigidity of the connecting part is strengthened.
What is a Capsule Slip Ring?
Capsule slip rings are a type of electrical connector that are used to transfer power and data between two rotating objects. They are commonly used in applications where there is a need to send or receive signals from a stationary object to a rotating one, or vice versa.
How Does it Work?
Capsule slip rings work by using a series of electrical contacts that rotate with the object on which they are mounted. These contacts are spaced evenly around the circumference of the ring, and as they rotate they make and break contact with corresponding contacts on the other object. This allows power and data to be transferred between the two objects without any interruption.
Advantages of Capsule Slip Rings
There are several advantages to using capsule slip rings in place of other types of electrical connectors.
For example, the rotation of the contacts causes them to be freely accessible and therefore free from dust and debris. This makes them ideal for applications where connector maintenance is often a problem.
Because the contacts are freely accessible, they can be readily replaced if a fault occurs. They also have very low electrical resistance, making them ideal for transmitting radio frequency signals. Because of the low resistance, this type of connector is often used in high-speed data transmissions.
This type of Conductive Slip Ring is similar to the shape of a hat. The brim part is a flange with a conductive slip ring. The function of the flange is to facilitate installation. It is connected to electrical equipment through the fixing hole of the flange. It can be firmly installed on the equipment. Therefore, the stator of the cap-type slip ring is generally fixed by the outer layer with a flange, and the inner part is the rotor with the inner shaft rotating. The stator and the rotor are not fixed, and the details will be different according to the installation method.

(2) High-speed milling The high-speed milling process developed in recent years has greatly improved the processing efficiency and achieved a very high surface finish. In addition, it can also process high hardness modules, and has the advantages of low temperature rise and small thermal deformation. The development of high-speed milling technology has injected new vitality into the manufacture of large-scale cavity molds in the automotive and home appliance industries. It has now evolved toward greater agility, intelligence, and integration.
1. CNC milling and machining center is used to complete the workpiece processing equipment with large milling amount. 2. CNC engraving and milling machine is used to complete small milling, or soft metal processing equipment. 3. High-speed cutting machine is used to complete medium milling. And processing equipment that minimizes the amount of grinding after milling
