Description

Technical Field

[0001] The utility model belongs to the technical field of parts processing, in particular to a punch used for processing a high-lock bolt driving groove. Background Art

[0002] In recent years, due to the increasing production tasks, the efficiency of traditional manual punching and squaring can no longer meet the production needs. At present, imported fully automatic punching and squaring machines have been introduced to increase production. However, the punches compatible with this equipment are still heavily dependent on imports. The punch manufacturing technology is subject to the market instability of others, and the high price and rapid wear rate of imported punches have led to an increase in product production costs. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above disadvantages and provide a punch with low wear and low cost for machining a high-lock bolt driving groove.

[0004] The purpose of the utility model and the solution of its main technical problems are achieved by adopting the following technical solutions:

[0005] The utility model discloses a punch for processing a high-lock bolt driving groove, comprising a limiting base, a purple titanium coating, a support rod, a butt head, and a punch, and is characterized in that the outside of the punch is covered with a layer of purple titanium coating, the punch and the support rod are integrated, the support rod and the butt head are integrated, and the purple titanium coating, the support rod, the butt head, and the punch are inserted into a stepped hole provided in the limiting base.

[0006] The support rod is cylindrical or conical.

[0007] One end of the limiting base is provided with a trumpet-shaped hole.

[0008] The punch is made of M42 high-cobalt toughness high-speed steel.

[0009] Compared with the existing technology, the present invention has significant beneficial effects. The above technical solution shows that by coating the outside of the punch with a layer of purple titanium coating, the punch and support rod are integrated, and the support rod and abutment are integrated. The purple titanium coating, support rod, abutment, and punch are inserted into a stepped hole provided in the limit base. Through physical and chemical testing and analysis of more than 10 imported materials, combined with the punch's operating environment, it was found that M42 high-cobalt toughness high-speed steel best meets the requirements. This material can also maintain good red hardness even during high-speed punching and upsetting. Regarding heat treatment, through more than 50 tests, suitable heat treatment methods such as quenching temperature, tempering temperature, and cooling time were designed to ensure that the punch achieves optimal hardness and maintains a certain level of toughness. Regarding surface treatment, the application of the purple titanium coating minimizes deformation of the plated punch, reduces the surface friction coefficient, and increases the surface hardness, greatly increasing the punch's wear resistance and thus significantly extending the punch's life. This achieves low wear and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is a detailed description of the specific implementation, structure, features and effects of the present invention in conjunction with the accompanying drawings and preferred embodiments.

[0020] Example 1

[0021] The present invention provides a punch for machining a high-lock bolt drive groove, comprising a positioning base 1, a purple titanium coating 2, a support rod 3, a butt 4, and a punch 5. The punch 5 is characterized in that the outer surface of the punch 5 is covered with a layer of purple titanium coating 2, the punch 5 and the support rod 3 are integrally formed, and the support rod 3 and the butt 4 are integrally formed. The purple titanium coating 2, the support rod 3, the butt 4, and the punch 5 are inserted into a stepped hole provided in the positioning base 1. The support rod 3 is cylindrical. A trumpet-shaped hole is provided at one end of the positioning base 1, and the punch 5 is plum blossom-shaped. The punch 5 is made of M42 high-cobalt toughness high-speed steel.

[0022] Example 2

[0023] The present invention provides a punch for machining a high-speed locking bolt drive groove, comprising a stop base 1, a purple titanium coating 2, a support rod 3, an abutment 4, and a punch 5. The punch 5 is characterized by being covered with a layer of purple titanium coating 2, integrally formed with the support rod 3, and the support rod 3 and abutment 4. The purple titanium coating 2, support rod 3, abutment 4, and punch 5 are inserted into a stepped hole provided in the stop base 1. The support rod 3 is conical, a trumpet-shaped hole is provided at one end of the stop base 1, and the punch 5 is hexagonal. The punch 5 is made of M42 high-cobalt, high-toughness, high-speed steel.

[0024] When in use, fix the limit base 1 on the fully automatic punching and squaring machine, put the head of the blank part into the trumpet-shaped hole at one end of the limit base 1, turn on the power switch, and the fully automatic punching and squaring machine will impact the head 4. The head 4 drives the support rod 3, the punch 5, and the purple titanium coating 2 to move. The punch 5 and the purple titanium coating 2 impact the blank part to form a driving groove. The head 4 contacts the limit base 1 to prevent the punch 5 and the purple titanium coating 2 from impacting the blank part too deeply.

[0025] The above description is only a preferred embodiment of the present invention and does not impose any type of limitation on the present invention. Any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
