一、概述利用液压成形工艺,可做到一次成形,并能简化模具,有效地提高经济效益。尤其是在冷作硬化敏感性十分强烈的奥氏体不锈钢成形中,可避免金属粘模现象。可是,目前对这一成形工艺的论述,往往侧重于液体起凹模作用的形式,如图1所示。但这一成形工艺仅适用于半圆形、抛物形、筒体、锥状筒体等底部呈穹凸状零件(如图2)。另一方面,对液体起凸模
First, an overview of the use of hydroforming process, can do a forming, and can simplify the mold, effectively improve economic efficiency. Especially in austenitic stainless steels that are very susceptible to cold work hardening, metal sticking can be avoided. However, the current discussion of this forming process tends to focus on the form in which the liquid acts as a die, as shown in FIG. 1. However, this forming process is only applicable to semicircle, paraboloid, cylinder, cone-shaped cylinder at the bottom of the dome-like parts (Figure 2). On the other hand, punch the liquid
