Development status and trend of automated production of high-speed precision stamping parts

The development status and trend of automated production of high-speed precision stamping parts. High-speed precision stamping equipment is composed of high-speed precision stamping equipment. High-speed presses are used for high-speed stamping of precision parts and require high precision, so they are also called high-speed precision presses. With the development of industry, the demand for functional stamping parts (stator and rotor silicon steel sheet stamping parts for micro motors, stator and rotor silicon steel sheet stamping parts for industrial motors, small transformer silicon steel sheets, easy-open lids, lead frames, connectors, etc.) is increasing. The increase has promoted the continuous improvement of the stamping efficiency of the press, and the application of high-speed presses has gradually been promoted. The high-speed press mentioned in this article refers to the high speed (pressing speed or feeding speed) that can meet the requirements of multi-station progressive dies. Press. The high-speed press needs to form an automated stamping line with racks, material leveling machines, feeders, molds and waste recycling devices to complete the stamping work. This requires the high-speed press to be able to connect with peripheral equipment in machinery and electrical appliances to achieve Monitoring and control of the stamping process (production count, material status, material thickness, feeding line height, punching force, punch speed, stroke, bottom dead center position, pneumatic system pressure, lubrication system temperature and flow, etc.) and control. Automated peripherals and testing equipment. Automated peripherals mainly include: feeder, cutting and welding machine, leveling machine, feeder, three-in-one feeder leveling feeder, oil feeder, negative pressure waste suction device, and receiving device. Testing equipment includes bottom dead center detector, waste up-regulation detector, error detection device and so on. Automated peripheral equipment and presses together form an automated stamping line. The use of automated stamping line production methods can reduce product costs, improve labor productivity, product accuracy, material utilization, and safety of production operations, while saving floor space and eliminating semi-finished products Inventory is easy to manage, thereby improving the competitiveness of manufacturing enterprises. Therefore, it is widely used in industries such as micromotors, microelectronics, automobiles, and home appliances. As there are many types of automated stamping lines, the automated peripheral equipment introduced here is mainly used in high-efficiency precision stamping lines combined with high-speed/fast presses. This type of press line is mostly used to produce large quantities of parts, such as the stator and rotor cores of micro motors and industrial motors, air conditioning fins, and precision lead frames. The minimum operating speed is about 100 operations/min (large press line), and the maximum can be more than 1,000 operations/min (small press line). The thickness of stamped parts is mostly less than 1.0mm, or even less than 0.1mm. Because of the large feeding step of the large-scale press line, although the operating speed of the press itself is not high, its feeding speed is much higher than that of the small press line.
