强力压边精冲是目前提高冲裁质量及应用最广泛的一种少无切削工艺。它一次冲裁能获得精度1～4级,光洁度▽6～▽9的零件。1922年德国人费礼兹·席斯(FriteSchiess)就发明了这种精冲方法并获得了专利。以后经过改进,特别是模具制造技术了进步,到五十年代逐步用于生产,并出现了专用的三动精冲压力机。五十年代在西欧精冲工艺进入实用阶段,精冲压力机进入研制阶段,1952年瑞士开始研制肘杆式精冲压力机,1956年开始研制全液压精冲压力机,1960年在Basel展览会上第一次展出了精冲压力机。
Strong edge pressure fine blanking is to improve the quality of blanking and the most widely used less non-cutting technology. It is a blanking time to obtain the accuracy of 1 to 4, finish ▽ 6 ~ ▽ 9 parts. In 1922 FriteSchiess German invented this fine blanking method and was patented. After the improvement, especially the mold manufacturing technology advances, and gradually used in the fifties production, and the emergence of a dedicated three moving fine punch press. In the fifties, the fine blanking process in western Europe entered the practical stage. The precision blanking press entered into the research and development stage. In 1952, Switzerland started to develop the elbow-bar type precision blanking press. In 1956, it started to develop the full hydraulic blanking press. In 1960, For the first time on the fine blanking press.
