Powerful cushion pad of die

Abstract

The invention provides a powerful cushion pad of a die, and relates to the technical field of stamping dies. The powerful cushion pad comprises a nitrogen spring, a sleeve and a rubber cushion pad, wherein the top of the nitrogen spring is connected with a supporting column, the bottom of the nitrogen spring is connected with a bearing base, the nitrogen spring is fixedly installed in a bottom diethrough the bearing base, the top end of the sleeve is located at the top of a lower die, the bottom of the sleeve is inserted into the lower die, the rubber buffer pad is of an annular structure andis connected to the bottom of the sleeve, and the bearing base is in a square block shape and is located inside the lower die. According to the powerful cushion pad of the die, a traditional polyurethane buffer pad is replaced with the nitrogen spring to conduct flexible buffer protection between the upper die and the lower die, and therefore the problems that due to buffer protection of the traditional polyurethane buffer pad, the polyurethane buffer pad is frequently damaged and replaced, and the workpiece stamping production cost is increased are solved.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, and more specifically relates to a strong cushioning pad for dies. Background technique [0002] In metal stamping dies, especially in large stamping dies, strong vibration will be generated every time the die is stamped and closed. This vibration will damage the die itself, reduce the precision of the die and reduce the service life of the die. To alleviate this hazard, buffer components are usually installed inside the die to protect the stamping die. [0003] The current common practice is to set four buffer pads made of polyurethane material inside the mold, which effectively reduces the vibration of the mold. Since the buffer pads are made of polyurethane material, the production batch of stamping dies is high. The damage is also very large, therefore, every time it is used for a period of time, the service life of the cushion pad has also reached, and a new cushion pad needs to be re...

Problems solved by technology

[0003] The current common practice is to set four buffer pads made of polyurethane material inside the mold, which effectively reduces the vibration of the mold. Since the buffer pads are made of polyurethane material, the production batch of stamping dies is high. The damage is also very large, therefore, every time it is used for a period of time, the service life of the cushion pad is up, and a new cushion pad needs to be replaced, and frequent replacement of the cushion pad will also cause considerable production costs
