Characteristics and Selecting Method of Impression Die Forging Equipment

2019-07-27 14:39:13

Impression die forging hammer, electric screw press, and hot die forging press are three main die forging machines in forging industry. Although the respective technology have been developed correspondingly for many years, they have different applicability due to the respective performance characteristics.

Disadvantages of hot die forging press

The main disadvantage of this die forging method is that the equipment structure is complex, the price is high, and the die structure is more complex than that of the common hammer forging die. At the same time, because the slider stroke can not be adjusted in the forging process, it can not carry out the operation of drawing, rolling extrusion and other steps which need multiple strikes to complete.

According to the above analysis and the requirements of precision die forging, it is possible to choose the right forging equipment according to the shape, material, forging amount, etc.
