Abstract
The utility model provides a square-hole full hollow nail, and belongs to the technical field of rivets. The square-hole full hollow nail solves the problems that the machining process of the conventional hollow nail is fussy, the rejection rate is high, and most importantly, the yield cannot meet the requirement due to low machining efficiency and the like. The square-hole full hollow nail comprises a head and a nail rod, wherein one end of the nail rod is integrally connected with the head; and a through hole is formed on the head and the nail rod through cold heading perforation. By adopting cold heading one-off forming, the machining efficiency of the square-hole full hollow nail is improved, burrs produced in the machining process are avoided, the production cost is reduced, the yield of the square-hole full hollow nail is improved, the machining process is simple and convenient, and the rejection rate is effectively reduced.
Description
Technical field
The utility model belongs to the rivet technology field, refers in particular to the full Full Tublar Rivet of a kind of square hole.
Background technique
The full Full Tublar Rivet of square hole applies in the accessory of special machine processing industry as a kind of special screw part.The full Full Tublar Rivet of former this type or semi-hollow nail are to form by special stage property machining, and course of working is comparatively loaded down with trivial details, and reject rate is higher, the most important thing is that the efficient of processing itself is not high, causes output can't reach requirement.
Summary of the invention
The purpose of this utility model provides a kind of burr that punches straight forming, avoided machining process to produce by cold-heading, the full Full Tublar Rivet that work efficiency is high.
The purpose of this utility model is achieved in that
The full Full Tublar Rivet of square hole comprises head and nail bar, and an end of described nail bar is connected with the head one, it is characterized in that: through the cold-heading drilling forming through hole is arranged on described head and the nail bar.
In the full Full Tublar Rivet of above-mentioned square hole, described through hole cross section is square or is oval.
In the full Full Tublar Rivet of above-mentioned square hole, the intersection of the bottom surface of described head and the intersection of through hole and nail bar and through hole is provided with the chamfering through the cold-heading drilling forming.
The utility model compared to existing technology outstanding and useful technique effect is:
1, the utility model adopts the cold-heading once-through, has improved the work efficiency of product, and the burr of having avoided machining process to produce has reduced cost of production, has improved the up-to-standard rate of product.
2, course of working of the present utility model simple and convenient, effectively reduce reject rate.

Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-5:
The full Full Tublar Rivet of square hole comprises head 1 and nail bar 2, and an end of described nail bar is connected with the head one, it is characterized in that: through the cold-heading drilling forming through hole 3 is arranged on described head and the nail bar.
Above-mentioned through hole 3 cross sections are square or are oval.
The intersection of the intersection of the bottom surface of above-mentioned head and through hole 3 and nail bar and through hole 3 is provided with the chamfering 4 through the cold-heading drilling forming.
Material is delivered under the drift, form through hole 3 by Impulsive force of punch pin, material is subjected to form under the momentum effect Full Tublar Rivet head simultaneously, the utility model course of working is simple, and the required equipment complexity of machining now is loaded down with trivial details, repeatedly processing has increased human cost, so this course of working greatly improved manufacturing efficiency, and there is not burr phenomena in finished product simultaneously.
Above-described embodiment is preferred embodiment of the present utility model only, is not to limit according to this protection domain of the present utility model, so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
