Precision stamping parts are produced by a series of stamping processing technologies such as stamping, extrusion, rolling, welding, cutting, etc. Precision stamping parts are difficult to manufacture. In order to meet production requirements and achieve good product forming effect, the stamping materials of precision stamping parts have higher requirements.So what are the requirements of stamping material for precision stamping parts?

1. The stamping performance required for the stamping materials of precision stamping parts

1, stamping materials should be easy to get high quality and high precision stamping parts, convenient for production and processing.

2. The limit deformation degree and the total limit deformation degree of the primary stamping process of the stamping material should be large enough to facilitate the improvement of production efficiency.

3, stamping materials for precision stamping parts, precision stamping die loss and wear should be low, and not easy to appear waste, easy to improve production.

2, the stamping material of precision stamping parts should meet the technological requirements

1. The thickness tolerance of stamping materials should meet the national standard: different die clearance is applicable to materials of different thickness. If the thickness tolerance of materials is too large, it will not only directly affect the quality of the punching parts, but also may cause damage to the mold or press.

2, the stamping material has a high surface quality: the stamping material surface clean and smooth, no oxide, crack, rust, scratch, stratification and other defects.Surface state good material, not easy to break in processing, not easy to scratch mold, precision metal stamping parts of the stamping parts of the surface quality is good.

3, the stamping material should have a good plasticity: the stamping material should have a higher elongation and sectional shrinkage, lower yield narrowing and higher tensile strength, higher plasticity, can deformation degree, is conducive to the stability of the stamping process and deformation uniformity, improve the precision of the stamping parts forming size accuracy.

4, stamping materials should be mechanical joint and continue processing (such as welding, polishing and other procedures) have a good adaptability, should not damage the mechanical equipment.

The stamping material of precision stamping parts is related to the performance and quality of the stamping parts.

High speed precision stamping equipment is a general term that includes automatic peripheral equipment and testing equipment of high speed press and high speed press.High speed press is used for high speed stamping of precision parts, which requires high precision, so it is also called high speed precision press.Along with the development of the industry, functional stamping parts (the stator silicon steel sheet stamping micromotor, industrial motor stator silicon steel sheet stamping, small transformer silicon steel sheet, easy pull cover, lead frame, connectors, etc.) increasing demand, prompting the stamping press efficiency enhances unceasingly, the application of high speed press gradually promoted, the high-speed press referred to in this article is able to adapt to multi-station progressive die requirements of high speed press (stamping speed or feeding speed).

High speed press needs and rack, leveling machine, feeder, mould materials and waste recycling device of automatic press line to accomplish the punching, it requires high speed press can on the mechanical and electrical, linking to the surrounding equipment for stamping process monitoring (counting, material status, material thickness, feed line height, impact force, punch speed, travel, bottom dead center position, temperature and flow pressure pneumatic system, lubrication system, etc.) and control.

Automatic peripheral equipment mainly includes: material rack, cutting welding machine, leveling machine, feeding machine, three-in-one material rack leveling feeder, oil feeder, negative pressure waste absorption device, material collection device.The detection equipment includes bottom dead point detector, waste up-rising detector, detection device, etc.Automation peripherals and press automation press line, the automatic press line production mode can reduce the product cost, improve labor productivity, the product precision, material utilization and production safety, save area at the same time, save intermediate goods inventory, facilitate management, thus enhancing the competitiveness of manufacturing enterprises, therefore, high-precision copper products are widely used in the micromotor, microelectronics, automotive industry and household appliances.
