Influence of high-speed punch accuracy on stamping products

2022-06-15

The impact of high-speed punching accuracy on stamping products: In modern stamping operations, if there are only high-precision, long-life molds without high-precision punches and high-quality stamping materials, it is impossible to achieve high-precision stamping processes. The precision and rigidity of the punch have a great influence on the life of the die. The same die shows different performance and service life on punches with different precisions. For example, on a punching machine with general precision, it will produce chipping after tens of thousands of times, while on a high-speed punching machine with super precision, chipping occurs after more than 1 million times.

The dynamic accuracy is directly related to the rigidity of each part of the punch, and the dynamic accuracy of the punch with good rigidity is relatively high.

If the high-speed punch is loaded, the structure and other pressure-bearing structures will be deformed. Therefore, the static accuracy will deteriorate, that is to say, the dynamic accuracy is the real accuracy.

There is a very close relationship between the accuracy of the punch press, the accuracy of the product and the life of the mold.

The dynamic accuracy is directly related to the rigidity of each part of the punch, and the dynamic accuracy of the punch with good rigidity is relatively high.

The dynamic accuracy, which is very important in actual stamping processing, has not been integrated and formulated due to the technical difficulties in formulating specifications. The current situation is that static accuracy represents the accuracy of punching machines.
