Description

Tooth-shaped forming die for part with teeth on end face

Technical Field

The utility model belongs to the technical field of machinery, a tooth profile of tooth part's forming die is taken to terminal surface is related to particularly.

Background

For a long time, the processing of the tooth shape of small parts with teeth on the end surfaces of materials difficult to process, such as high-temperature alloy and the like, is difficult, and the conventional mode basically uses a hobbing cutter for hobbing, but as the processing materials are special, and in addition, the small parts are processed, the hobbing cutter for hobbing is worn extremely quickly, so that the problems of high processing cost, low processing efficiency, large batch production difficulty and the like are caused.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned shortcoming and provide a tooth profile forming die of tooth part is taken to terminal surface with low costs, efficient, product quality is good, but batch production.

The purpose of the utility model and solve its main technical problem and adopt following technical scheme to realize:

the utility model discloses a tooth profile forming die of a part with teeth on the end surface, which comprises a heading tooth male die, a die cavity, a die pad, a mandril and a guide round female die, wherein the die pad is arranged on the die cavity; the lower end head of the upsetting tooth male die is inserted into the upper end of the guide round female die, a plurality of annularly arranged teeth are arranged on the lower end face of the upsetting tooth male die, a groove is formed in the center of the upsetting tooth male die, and a die filling cavity is sleeved outside the guide round female die.

And die cushions are arranged below the die cavity and the guide round female die, and ejector rods are inserted into the die cushions.

The heading tooth male die can move up and down in the guide round female die.

The ejector rod can move up and down in the die cushion.

Compared with the prior art, the utility model has obvious beneficial effects; the technical scheme shows that: a plurality of annularly arranged teeth are arranged on the lower end face of the heading tooth male die, a groove is formed in the center of the heading tooth male die, and blank parts to be formed into tooth shapes are heated and then placed into the guide round female die. The upsetting tooth male die descends along with an upper die base of the press machine, the upsetting tooth male die enters the guide round female die, and the part is continuously upset downwards under the guide effect of the guide round female die, so that the pressure of the press machine is transmitted to a plurality of annularly arranged teeth arranged on the lower end face of the upsetting tooth male die, and the end faces of the part are pressed into a plurality of annularly arranged tooth shapes by the plurality of annularly arranged teeth under the action of the pressure; the end face tooth shape is formed through the tool, in terms of efficiency, the forming process of the end face tooth shape is about 4 seconds, and the machining efficiency is improved by more than 10 times compared with a traditional hobbing mode; in terms of performance, a small groove (when no hole is formed in the center of a part, the small groove is not formed in the lower end face of the upsetting male die), the groove is designed to achieve metal center shunting during upsetting of the tooth profile, and the metal can easily flow during plastic forming, so that the upset tooth profile is fuller. The tooth profile formed by the forming mode is full, and the metal flow line is well preserved due to plastic forming, so that the performance of the end face tooth profile formed by the forming mode is far superior to that of an end face tooth profile processed by a traditional hobbing mode; in addition, in the aspect of processing cost, the tool uses a hot heading mode when forming the end face tooth profile, and the blank made by heating and heading reduces the deformation resistance of materials, so the tooth profile forming force is relatively small, the service life of a die is greatly prolonged, the processing cost of tooth profile processing is reduced, the cost is saved by more than 3 times compared with the traditional hobbing processing mode by initial estimation, and the problem that the traditional processing mode cannot be produced in batches is solved. In summary; the utility model discloses with low costs, efficient, product quality is good, but batch production.

Detailed Description

The following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

The utility model discloses a tooth-shaped forming die of a part with teeth on the end surface, which comprises a heading tooth male die 1, a die cavity 2, a die pad 3, a mandril 4 and a guide round female die 5, wherein the heading tooth male die is provided with a plurality of guide grooves; the lower end head of the upsetting tooth male die 1 is inserted into the upper end of the guide round female die 5, a plurality of annularly arranged teeth are arranged on the lower end face of the upsetting tooth male die 1, a groove is formed in the center of the upsetting tooth male die, and a die filling cavity 2 is sleeved outside the guide round female die 5.

And a die cushion 3 is arranged below the die filling cavity 2 and the guide round concave die 5, and a mandril 4 is inserted into the die cushion 3.

The heading tooth male die 1 can move up and down in the guide round female die 5.

The ejector pin 4 can move up and down in the die pad 3.

When the upsetting tooth male die is used, referring to fig. 6, a male upsetting tooth die 1 is arranged on an upper die base of a pressure device, a mandril 4, a die pad 3, a die filling cavity 2 and a guide round female die 5 are arranged in a die filling cavity of a lower die base of the pressure device, a press machine is started, after debugging is completed, a heated blank part 6 is placed in the guide round female die 5, the upsetting tooth male die 1 descends along with the upper die base of the press machine and enters the guide round female die 2, the upsetting part 6 continues to descend under the guide effect of the guide round female die 2, so that the pressure of the press machine is transmitted to female teeth of the upsetting tooth male die 1, the female teeth enable the blank upper end surface of the part 6 to be plastically deformed under the pressure, further, the tooth shape of the upper end surface of the part is formed, the forming and the complete forming are finished along with the operation of the pressure device, then the upsetting tooth male die 1 ascends along with the pressure device, exits the guide round female die 5 to reach the upper dead point of the pressure device, and simultaneously, a cylinder on the pressure device works, and pushes the mandril 4 to withdraw the part 5 to complete a work cycle.
