Description

A stamping die for automobile end cover capable of improving the uniformity of force on finished products

Technical Field

The utility model relates to the technical field of stamping dies, and more specifically to an automobile end cover stamping die which can improve the force uniformity of a finished product.

Background Art

Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

The utility model patent with patent application publication number CN202220960725.5 discloses a stamping die for an automobile end cover that can improve the uniformity of force on the finished product, including a frame, a linear drive hydraulic cylinder and a punching head. A stabilizing mechanism and a cleaning mechanism are also provided on the frame. The frame includes a base, a top plate, a drive plate and four guide rods. The stabilizing mechanism includes a screw, a rotating shaft, a connecting seat, a gear, a rack, a synchronous belt, two synchronous wheels and two stable clamping assemblies. The advantage of this structure is that it can assist in fixing the two sides of the automobile end cover through two stable clamping assemblies, thereby improving the stability of the automobile end cover during the stamping process and improving the uniformity of force on the finished product. The automobile end cover can be assisted in fixing without increasing the driving source, thereby reducing the investment in production costs. At the same time, due to its transmission connection with the drive plate, the synchronization rate between the stabilizing mechanism and the drive plate is better, thereby improving production efficiency. The cleaning mechanism can also clean dust during the processing process.

However, in actual use, since this structure cleans the dust by passing compressed air from an external air source into the air pipe, it is easy to cause dust to fly in the air during cleaning, which will cause damage to the health of the workers.
