Description

Technical Field

[0001] The present application relates to the field of pressing tooling, and in particular, to a pressing mechanism. Background Art

[0002] With the development of the automobile industry, more and more auto parts are using die castings. At the same time, the shapes of automobile die castings are becoming more and more complex. For example, various parts need to be pressed on die castings. Different press-fitting mechanisms need to be designed to meet the press-fitting requirements for different types of parts.

[0003] The usual press mechanism is a cylinder driving a press arm to press a certain point of the workpiece. For some larger workpieces, as the size increases, the number of positions that need to be pressed increases, resulting in an increase in the number of attached press mechanisms. As a result, the entire press mechanism occupies too much table space, and interference between mechanism movements often occurs. Utility Model Content
