近年来,以节省材料和能源出发,在模锻方面,提出了提高模锻件的材料利用率和省略以后的加工工序以及模锻车间的工作环境和防止公害等问题。对这一切问题正在积极努力加以解决。以往广泛采用以下三种模锻方法使坯料变形到所需形状。第一种是利用锻造压力机和锤进行模锻的方式(图1)。这样成形的模锻件 In recent years, in order to save material and energy, in the aspect of die forging, some problems such as improving material utilization ratio of die forging, omitting the subsequent processing steps, working environment of die forging workshop and preventing pollution have been put forward. We are working hard to solve all these problems. In the past, the following three forging methods were widely used to deform the blank to the desired shape. The first is the way to forge forging presses and hammers (Figure 1). This form forging pieces
