Sealing device provided with male die stamping die and use method of sealing device

Abstract

The invention discloses a sealing device provided with a male die stamping die and a use method of the sealing device and belongs to the field of stamping dies. The sealing device provided with the male die stamping die comprises a sealing device body. A female die is arranged at the lower end of the sealing device body. The female die is fixedly connected with the sealing device body. A male dieis arranged on an upper end cover of the female die. The sealing device body is located between the female die and the male die, and the upper end of the sealing device body extrudes and makes contactwith the lower end of the female die. A transverse elliptical cavity is cut in the inner end of the sealing device body, and a hollow supporting pipe is fixedly connected to the inner wall of the transverse elliptical cavity. An elastic deforming mechanism is arranged in the hollow supporting pipe. Due to use of the elastic deforming mechanism, strength and shock resistance of the sealing devicebody are improved, the interior of the sealing device body is not likely to be cracked, meanwhile, the cracking phenomenon in the sealing device body can be judged according to color changes of the positions of printing ink which changes color when touching water, workers can be reminded of replacing the sealing device body with a new sealing device body in time, and therefore it can be ensured that the sealing performance between the male die and the female die is good.

Description

technical field [0001] The invention relates to the field of punching dies, more specifically, to a sealing device provided with punching dies and a method for using the same. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. Forming die refers to the use of various local deformation methods to change the shape of the blank. Its forms include convex forming dies, edge forming dies, neck forming dies, hole flange forming dies, and round edge forming dies. [0003] In order to ensure the tightness of the mold cavity during product molding, the existing stamping dies generally...

Problems solved by technology

[0003] In order to ensure the tightness of the mold cavity during product molding, the existing stamping dies generally have a sealing ring between the punch and the die, but the sealing ring is prone to aging and cracking after a period of time, which affects the sealing. The surface is cracked, and the staff can see to replace the new seal ring, but when the seal ring is cracked inside, it is not easy to detect, thus affecting the sealing of the mold cavity
