一、前言我们进行液压机械压延这项新工艺的试验研究和生产已经三年了。这项工艺的基本原理如图1所示。利用液压机带动凸模1(与零件的形状一致)将毛坯板料2压入由板坯2本身、密封圈3、凹模座4和凹模板6组成的密闭腕体内,腔体内充满了液体,由此,液体压力很快 I. INTRODUCTION We have carried out the experimental research and production of this new technology for hydraulic mechanical rolling for three years. The basic principle of this process is shown in Figure 1. The hydraulic machine is used to drive the punch 1 (consistent with the shape of the part) to press the blank sheet 2 into the closed wrist formed by the blank 2 itself, the sealing ring 3, the die holder 4 and the die plate 6, the cavity is filled with liquid, As a result, liquid pressure is fast
