Punch accuracy In the high-speed press punching production

Punch accuracy In the high-speed press punching production, the punch accuracy is very important. Punch precision directly affects the accuracy of stamping products, die life. The accuracy of the punch can be divided into the static accuracy and the dynamic accuracy of the load when the punch is not loaded. High-speed press punching is very important in the actual production of dynamic accuracy, due to the use of presses, the actual load changes in volume is very large Busbar Processing Machine, so specifications are technically difficult, it has not yet integrated development CNC Drilling Machine, the status quo is static accuracy to represent the precision punch. In modern stamping operations, if only high-precision, long life mold, without high-precision punch and punching materials with high-quality, is unable to achieve high-precision stamping process. Punch precision and rigidity of the life of a great impact on the mold, the same mold in a different punch on the punch to show different performance and service life. Such as in the general accuracy of the punch on the use of tens of thousands of times that chipping, and in the high-precision precision punch on more than 1 million times have chipping phenomenon. Dynamic accuracy and punch parts of the rigidity are directly related to the rigidity of a good punch accuracy is relatively high dynamic CNC Busbar Punching Machine. If the punch load, structure and other compression structure will be deformed. So the static accuracy will deteriorate, you can say that dynamic accuracy is the real precision. Punch precision and accuracy of the product, die life has a very close relationship between. The dynamic accuracy is directly related to the rigidity of each part of the press, and the dynamic accuracy of the punch with good rigidity is relatively high.
