Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of parts processing, and in particular relates 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 processing 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 present invention is to overcome the above disadvantages and provide a punch with low wear and low cost for machining a high locking bolt driving groove.
[0004] The purpose of the present invention and the solution of its main technical problems are achieved by adopting the following technical solutions: The present invention 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 set in the limiting base.
[0005] The support rod is cylindrical or conical.
[0006] One end of the limiting base is provided with a trumpet-shaped hole.
[0007] The punch is made of M42 high-cobalt toughness high-speed steel.
[0008] Compared with the prior art, the present invention has obvious beneficial effects; it can be seen from the above technical scheme that: by covering the outside of the punch with a layer of purple titanium coating, the punch and the support rod are integrated, the support rod and the abutment are integrated, and the purple titanium coating, the support rod, the abutment, and the punch are inserted into the stepped hole set in the limit base. Through the physical and chemical test analysis of more than 10 imported materials, combined with the use environment of the punch, the material that best meets the use requirements is M42 high-cobalt toughness high-speed steel, which can also maintain good red hardness when punching and upsetting materials at high speed. In terms of heat treatment, through more than 50 tests, suitable heat treatment methods such as quenching temperature, tempering temperature, and cooling time are designed to make the punch reach the optimal hardness and maintain a certain toughness. In terms of surface treatment, the purple titanium coating is applied, the deformation of the punch after plating is very small, the surface friction coefficient is reduced, and the surface hardness is increased, so that the wear resistance of the punch is greatly increased, thereby greatly extending the life of the punch. Low wear and low cost are achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The specific implementation methods, structures, features and functions of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0012] Embodiment 1 The present invention discloses a punch for processing a high-lock bolt driving groove, comprising a limiting base 1, a purple titanium coating 2, a support rod 3, a butt 4, and a punch 5, characterized in that: the outside of the punch 5 is covered with a layer of purple titanium coating 2, the punch 5 is integrated with the support rod 3, the support rod 3 is integrated with the butt 4, and 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 limiting base 1. The support rod 3 is cylindrical. A trumpet-shaped hole is provided at one end of the limiting base 1, and the punch 5 is plum blossom-shaped. The punch 5 is made of M42 high-cobalt toughness high-speed steel.
[0013] Embodiment 2 The present invention discloses a punch for processing a high-lock bolt driving groove, comprising a limiting base 1, a purple titanium coating 2, a support rod 3, a butt 4, and a punch 5, characterized in that: the outside of the punch 5 is covered with a layer of purple titanium coating 2, the punch 5 is integrated with the support rod 3, the support rod 3 is integrated with the butt 4, and the purple titanium coating 2, the support rod 3, the butt 4, and the punch 5 are inserted into a stepped hole set in the limiting base 1. The support rod 3 is conical, a trumpet-shaped hole is set at one end of the limiting base 1, and the punch 5 is hexagonal. The punch 5 is made of M42 high-cobalt toughness high-speed steel.
[0014] When in use, fix the limiting 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 limiting base 1, turn on the power switch, and the fully automatic punching and squaring machine will impact the butt 4. The butt 4 drives the support rod 3, the punch 5, and the purple titanium coating 2 to move, and the punch 5 and the purple titanium coating 2 impact the blank part to form a driving groove. The butt 4 contacts the limiting base 1 to prevent the punch 5 and the purple titanium coating 2 from impacting the blank part too deeply.
[0015] 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 made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the technical solution of the present invention.
