Abstract

The utility model relates to the technical field of rivet dies, and aims to provide a rapid rivet processing die which comprises a punch die and a punch die, wherein a semicircular groove for rivet forming is formed in one end of the punch die, a circular hole matched with the punch die is formed in the center position of one end, far away from the semicircular groove, of the punch die, and the punch die is detachably inserted into the circular hole. The beneficial effects are that: according to the utility model, the convex punch die is changed into the nested die, so that the strength of the punch is enhanced, the stress concentration is reduced, the die breakage is prevented, the production efficiency of rivet processing is improved, and the problem that the existing stamping die is easy to break and the production efficiency of rivets is seriously affected is effectively solved.

Description

Quick processing rivet mould

Technical Field

The utility model relates to the technical field of rivet dies, in particular to a die for rapidly processing rivets.

Background

The pneumatic rivet gun is a professional hand tool for manufacturing industrial fastening riveting of various metal plates, pipes and the like, is one of main methods for manufacturing square or straight rod screws such as square or hexagonal screws into round rivets, is widely applied to various fields at present, and is shown in a common punch die diagram (shown in figure 1), and the common punch die is a convex die, and has the defects that the strength of the convex punch die is insufficient, repeated impact and stress concentration are realized, the rivet operation cannot be carried out for a long time and in a large quantity, the punch die is frequently broken, and the production efficiency is seriously influenced.

Disclosure of Invention

The utility model aims to provide a fast rivet processing die for solving the problems in the background technology.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a fast processing rivet mould, includes drift mould 2 and punch mould 3, the one end of drift mould 2 is provided with the semicircular groove that is used for rivet fashioned, and the other end of drift mould 2 can be dismantled and be provided with punch mould 3.

The center of the other end of the punch die 2 is provided with a round hole matched with the punch die 3.

The punch die 3 is inserted into the circular hole.

The depth of the circular hole is one third of the length of the punch die 3.

In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:

according to the utility model, the convex punch die is changed into the nested die, so that the strength of the punch is enhanced, the stress concentration is reduced, the die breakage is prevented, the production efficiency of rivet processing is improved, and the problem that the existing stamping die is easy to break and the production efficiency of rivets is seriously affected is effectively solved.

Detailed Description

The present utility model will now be described in detail with reference to the drawings and the specific embodiments thereof, wherein the illustrative embodiments and descriptions of the utility model are for illustration, but not for limitation.

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 4, the fast rivet processing die comprises a punch die 2 and a punch die 3, wherein one end of the punch die 2 is provided with a semicircular groove for rivet forming, the diameter of the arc-shaped groove is larger than that of the head of the screw 1, a circular hole matched with the punch die 3 is formed in the center position of one end, far away from the semicircular groove, of the punch die 2, and the punch die 3 is detachably inserted into the circular hole.

The depth of the circular hole is one third of the length of the punch die 3, so that the stability of connection between the punch die 3 and the punch die 2 can be effectively improved.

When the rivet manufacturing device is used, the head of the screw 1 is heated, and then the rivet gun is used for applying impact force to the nested die and the screw 1, so that the screw head is punched and deformed into a dome-shaped rivet, the rivet manufacturing is finished, and the rivet manufacturing work can be finished rapidly and accurately by using the nested die.
