Description

Female die for punching six holes of automobile transmission shaft retainer

Technical Field

The utility model belongs to technical equipment for machining holes, and relates to a female die for punching six holes of an automobile transmission shaft retainer.

Background

An existing female die for punching six holes of an automobile transmission shaft retainer is shown in figures 1-4, a groove 6 which gives way to a positioning disc 8 for punching six holes of the automobile transmission shaft retainer is arranged at the left edge of a female die body 1 of an existing female die 9, the thickness of the left edge of the female die body 1 is reduced by the groove 6 at the left edge of the female die body 1, the strength of the female die body 1 is weakened, the female die 9 is prone to fracture during working, production interruption is caused, and parts are scrapped.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide the female die for punching the six holes of the automobile transmission shaft retainer, which has the advantages of reasonable structure, high strength, long service life and low consumption cost, and can improve the yield of processed parts.

The technical scheme adopted for achieving the purpose of the utility model is that the female die for punching the six holes of the automobile transmission shaft retainer comprises a female die body, wherein a cavity which is in contact with a part to be punched and a blanking hole which is positioned below the cavity are arranged on the female die body.

According to the female die for punching the six holes of the automobile transmission shaft retainer, the structure that the die cavity is connected with the left edge of the female die body through the transition arc is adopted, and the structure that the groove is arranged on the left edge of the female die body in the prior art is abandoned, so that the thickness of the left edge of the female die is increased, the strength of the female die is improved, and the female die has the advantages of reasonable structure, long service life, low consumption cost, capability of improving the yield of processed parts and the like. The punching die is suitable for punching six holes of automobile transmission shaft retainers with various specifications.

In the figure: 1. the automobile transmission shaft structure comprises a female die body, 2 parts of a cavity, 3 parts of blanking holes, 4 parts of transition arcs, 5 parts of connecting holes, 6 parts of grooves, 7 parts of an automobile transmission shaft retainer, 8 parts of a positioning disc, 9 parts of an existing female die and 10 parts of the female die.

Detailed Description

The utility model is further illustrated by the following figures and examples.

Referring to fig. 5-9, the female die for punching six holes of the automobile transmission shaft retainer of the utility model comprises a female die body 1, wherein a cavity 2 which is contacted with a part to be punched and a blanking hole 3 positioned below the cavity are arranged on the female die body 1, and a connecting hole 5 which is fixed with a fixed base is also arranged. The left side of the cavity 2 is provided with a transition arc 4 connected with the cavity 2, and the cavity 2 is connected with the left edge of the female die body 1 through the transition arc 4.

Referring to fig. 8 and 9, the punching process of the six holes of the automobile transmission shaft retainer is the same as the prior art. Briefly described as follows: when six holes of the automobile transmission shaft retainer 7 are punched, the bottom end of the automobile transmission shaft retainer 7 is placed in a cavity 2 of a female die 10, the automobile transmission shaft retainer 7 is arranged on a positioning disc 8, the positioning disc 8 supports the automobile transmission shaft retainer 7 to rotate along with a manipulator on punching equipment in a positioning mode, a punch for machining sequentially completes machining of the six holes of the automobile transmission shaft retainer, and punched residual materials fall from a blanking hole 3 located below the cavity 2. Due to the fact that the die cavity 2 is connected with the left edge of the die body 1 through the transition arc 4, the thickness of the left edge of the die 10 is increased, the strength of the die 10 is improved, the service life is prolonged, the consumption cost is reduced, and the yield of processed parts can be improved. The female die for punching the six holes of the automobile transmission shaft retainer has good effect after 6-month trial.

The detailed description of the present invention is not exhaustive, and it should be noted that, for those skilled in the art, various modifications and improvements can be made without departing from the principle of the present invention, and these should be construed as the protection scope of the present invention.

Claims

1. A female die for punching six holes of a retainer of an automobile transmission shaft is provided with a female die body, wherein a cavity which is contacted with a part to be punched and a blanking hole which is positioned below the cavity are arranged on the female die body.
