Description

Compressor high pressure cylinder gasket stamping die

technical field

The present invention relates to a stamping die, in particular to a stamping die for gaskets in high pressure cylinders of compressors. the

Background technique

Gaskets in high-pressure cylinders of compressors are generally formed by cold stamping. However, the gasket in the compressor high-pressure cylinder produced by the existing stamping die for the gasket in the high-pressure cylinder of the compressor has poor surface finish and low production efficiency. the

Contents of the invention

The purpose of the present invention is to provide a stamping die for gaskets in high-pressure cylinders of compressors. the

The invention aims to solve the problems of poor surface finish and low production efficiency of the gaskets produced by existing stamping dies for producing gaskets in high-pressure cylinders of compressors. the

For realizing the purpose of the present invention, the technical scheme that the present invention generally adopts is:

The present invention comprises upper mold base and lower mold base,

The lower die base is provided with stopper pins, blanking dies, shaping dies, first hole dies, second hole dies, fixed feeding plates, die fixing plates and guide posts, and the die fixing plates are located on Fix between the unloading plate and the lower die base; the upper die base is equipped with a blanking punch, a shaping punch, the first punching punch, the second punching punch, a press-in type handle and a guide sleeve, and the upper die base is connected to the falling punch. There is a punch backing plate between the material punches, and a punch fixing plate under the punch backing plate; the guide post is set in the guide sleeve.

The beneficial effect of the present invention is: because the structure of the gasket in the high-pressure cylinder of the compressor is relatively complicated, it needs multiple processes such as punching, shaping, and blanking to complete. The mold is a multi-process mold. the

The invention has the characteristics of high production efficiency, and the initial positioning is carried out by the stopper pin, and the fine positioning is carried out by the guide pin to ensure the relative position accuracy of the gasket. The gasket in the high-pressure cylinder of the compressor produced by the invention has a smooth surface, reduces gas leakage, and can improve compressor efficiency. the

Description of drawings

Fig. 1 is a schematic diagram of the structure of the stamping die of the present invention. the

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. the

As shown in the figure, the present invention includes an upper mold base 1 and a lower mold base 15 . Lower mold base 15 is provided with retaining pin 18, blanking die 19, shaping die 21, the first hole die 2, the second hole die 9, fixed feeding plate 16, die set plate 13 and guide Column 14, die fixing plate 13 are located between the fixed feeding plate 16 and the lower mold base 15; the upper mold base 1 is equipped with a blanking punch 4, a shaping punch 6, a first punching punch 7, a second punching punch Hole punch 8, press-in mold handle 5 and guide sleeve 11, punch backing plate 3 is provided between upper die base 1 and blanking punch 4, punch backing plate 3 is provided with punch fixing plate 10; guide post 14 is sleeved in the guide sleeve 11. the

The working principle of stamping die of the present invention is:

First, the strips used for blanking are sent into the stamping tool through the material guide plate 12. Whenever the strips are fed into the length of a step, the press is connected to the die handle and operates back and forth once, punching, shaping, and blanking punches are completed respectively. blanking. When punching is completed, unload through the set fixed unloading plate. The punching process is mainly divided into three stages: punching, shaping, and blanking. Due to the large area of the punched hole, in order to ensure the quality of the punched part, the punch in the stamping die uses a guide pin 20, a guide pin 17 Carry out punching and guiding.
