- General all-steel punching die’s punching accuracy
Accuracy of panel punching part is display the press accuracy of the die exactly. But the accuracy of any punching parts’ linear dimension and positional accuracy almost depend on the blanking and blanking accuracy,. So that the compound mould of compound punching’s accuracy, is typicalness and representation in the majority.
Analyse of the die’s accuracy
For the analyse of pracyicable inaccuracy during production of dies to inactivation, we could get the tendency when it is augmentation in most time. From this we could analyse the elements. When the new punch dies pt into production to the first cutter grinding, the inaccuracy produced called initial error; if the die grinding more than twenty times, until it’s discard, the inaccuracy called conventional error; and bef普通全钢冲模的冲压精度分析
板料冲压件的精度准确显示出其冲模的冲压精度。而任何冲件的线性尺寸精度与形位精度主要取决于冲模冲裁和立体成形冲压件展开平毛坯的落料精度。因此，多工步复合冲压的单工位复合模、多工位连续模的冲压精度，在普通冲压的众多种类与不同结构的冲模中，最具典型性和代表性。
