Verify whether the die can stably punch out qualified parts. Because a stamping part is produced by several process processes such as product design, process design, mold design, die part processing and mold assembly, any work error may affect the quality of the parts. Therefore, after the die processing and assembly, it must be tested first, and then the quality of the test piece meets the requirements of the drawing. Finally, according to the existing problems, the causes of the punch are analyzed and the correction is made to make the mold can be stably punched out of the qualified parts.

The dimensional accuracy of stamping parts of precision punch equipment is guaranteed by the die, so its quality is stable and has certain interchangeability.

According to the requirements of stamping processing on the shape and size of stamping parts, different stamping processing methods should be adopted for stamping parts with different shapes and sizes. Therefore, the specific requirements of stamping processing on the shape and size of stamping parts by various high-speed presses are as follows:

The production of high-speed punch with automatic feeding device can be automated, which can save labor and improve productivity. However, the speed of ordinary punch is not fast, and there is a certain risk.

High speed punch has good stability and high precision. It is 5-10 times higher than that of ordinary punch press.

How to select the copper sleeve of the combined punch press? The 30 ton high-speed precision automatic punch press adopts the double braking structure in order to improve the braking effect due to the high number of revolutions of the driven part of the transmission system and the large kinetic energy of the driven part. That is to say, double brakes are used.
