As the demand for high-speed precision presses continues to grow, the competition among domestic manufacturers continues to increase, and more and more high-speed precision presses are exported abroad. With the rapid development of product technology in electronic communications, electrical appliances, automobiles and home appliances, the demand for precision and functional stamping parts is increasing, and the technical requirements are also getting higher and higher. Therefore, in mass and super mass production, ordinary stamping equipment can no longer meet the production and technical requirements. Using precision high-speed stamping machines for high-speed, automated and continuous stamping is an effective way to improve stamping productivity.
This article mainly introduces the current status and latest trends of high-speed precision presses.
High-speed precision presses are the greatest productivity in the stamping and stamping process. The number of strokes per minute of the slider of the high-speed precision press is more than 5 times that of the ordinary press of the same specification. The use of the high-speed precision press can not only obtain high-precision and high-quality stamping parts, but also extend the service life of the mold. There are many manufacturers of high-speed punching machines, and the technical characteristics of each manufacturer may be different, but they are all automatic punching machines for continuous high-speed punching and high precision.
High-speed precision presses and high-speed punches are used for a large number of products that must be produced by sheet metal processing. The stator and rotor plates of motors and generators are classic products of high-speed stamping. Even small tolerance deviations can cause eddy currents, which can lead to overheating of electromechanical components.
Each motor or generator requires hundreds of sheets of exactly the same shape. This requires a production process designed for mass production with consistent quality. This is where JDM's high-speed precision presses are used. They can achieve particularly high stroke frequencies and correspondingly fast cycle times.

Common high-speed precision presses have the following 4 characteristics
The high-speed precision automatic press manufactured by JDM has the following characteristics:
The body and frame have high strength and excellent shock absorption performance.
The high-speed precision press has high transmission accuracy. In the case of high-speed stamping and feeding, the machine body remains stable with minimal vibration, ensuring the long-term accuracy of the machine tool.
The frequency conversion of the main drive mechanism ensures smooth movement. Using constant temperature lubrication system, professional technical team design, reduce wear and greatly improve service life.
The high-speed precision press has fast response, high precision and reliable clutch control.
Various specifications are complete to meet the requirements of higher material requirements, higher precision and higher speed.
The high-speed punch produced by JDM has complete energy saving, environmental protection and safety measures.
We introduce the development status of high-speed precision presses from two aspects at home and abroad.
The world's first high-speed precision press was manufactured by the American HENRY&WRIGHT company in 1910, and it was called a die-cutting machine at that time. It is a low-transmission high-speed precision press with the advantages of low center of gravity, good stability, low horizontal force of the transmission system, and convenient operation. It was still the representative model of high-speed precision presses until 1955. However, due to the larger mass of the reciprocating part and the larger number of strokes of the slider, the vibration problem caused by the inertial force is more serious. In 1953, the German Schuler Company produced the first 1250kN closed double-point top drive high-speed precision press. The stroke of the press is 20mm and the stroke number is 150 SPM. It is the representative structure of the upper drive high-speed precision press. During this period, the Swiss company Brudler developed the BSTA series of column-type top-drive high-speed precision presses with an open structure body. The BSTA41 400kN high-speed precision press developed in the early 1970s reached an ultra-high speed of 1200spm. In 1974, the American Munster Company launched the "Hummingbird" 550kN closed double-point ultra-high-speed precision press with a stroke number of 1600 SPM. The HB2-30 type 270kN closed double-point ultra-high-speed precision press was developed in 1975. The number of high-speed precision pressure strokes is further increased to 2000 SPM. Today, Japan's MACH-100 ultra-high-speed precision press has reached 4000 SPM under the conditions of 100kN and 8mm stroke.
After 2000, thanks to the rapid development of the home appliance industry and the automobile industry, as well as the improvement of the mold manufacturing level, the market demand for high-speed precision presses has been driven. The domestic high-speed precision press manufacturing industry has begun to enter an era of rapid development. Today, a market is in full bloom and a hundred schools of thought contend. At present, the domestic mainstream high-speed precision press manufacturers mainly include Ningbo JDM, Yangzhou Forging, Yangli Group, Xuzhou Forging, Ningbo Taiyida, Zhejiang Zhongding, Shandong Jinjian, etc.
Among them, the GD series closed double-point high-speed precision press developed by JDM adopts a dual-power drive system (that is, a structure in which dual motors, dual flywheels, and dual clutch brakes are distributed at both ends of the spindle) to avoid mold jamming. , A unique four-pillar overhead cylinder is designed. The working capacity range of the press is 630～3000kN, the stroke of the slider is 30mm, and the number of strokes can reach 150～400 times per minute.
With the advent of Industry 4.0 and the continuous development of automation and information technology, the use of motors has become more and more extensive, and the requirements for motors have become higher and higher. In the compressor industry, due to the national regulations that refrigeration and air-conditioning compressors need to meet the secondary energy consumption standard, the thickness of the core of the compressor motor has dropped from 0.5mm to 0.3mm, and there is a trend of continued thinning. At the same time, due to the rapid development of electric vehicles and hybrid new energy vehicles, the prime mover is a high-power motor with high speed, low consumption and wide speed range, which puts forward a more severe test on the quality of the stator and rotor cores of the motor. Ordinary high-speed precision presses can no longer meet the production needs of this type of product.
On the premise of studying the development level of domestic and foreign presses, Ningbo JDM GD-L series of wide-table ultra-high-speed precision presses (working capacity is 2000～4000kN) are designed to meet the needs of the new energy automobile industry, integrated compressor motors, etc. The high-end motor manufacturing industry requires ultra-precision and high-speed stamping, and provides stamping equipment reserves for product upgrades, energy saving and consumption reduction in the small and medium motor manufacturing industry. The technical indicators of the new high-speed precision press have reached the international advanced level, with independent intellectual property rights, mastered the core technology of the new high-speed precision press, and have been practically applied in high-end motor core manufacturing enterprises.
With the continuous changes in market demand, the research direction and production capacity of manufacturers are constantly changing and progressing. So far, the development trends of high-speed precision presses are as follows:
In short, under the premise of ensuring quality, higher speed, higher efficiency, smaller energy consumption, and more convenient operability are the future development trend of high-speed precision presses and the goals pursued by stamping equipment manufacturers. .
Similar to many other industrial equipments, China's high-speed precision presses have gradually gone abroad, and more and more are sold to overseas markets, and with their excellent quality and competitive prices, they have won a lot of praise. Why are high-speed precision presses made in China a popular choice in the market? We have listed the following reasons.
