Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0015] Such as figure 1 — image 3 As shown, the present invention discloses an ancient special-shaped cold heading. In a specific embodiment of the invention, it includes a special-shaped cold heading body 1. The special-shaped cold heading body 1 is cylindrical, and the special-shaped cold heading The middle end of the upset body 1 is provided with an annular protruding ring 101. The annular protruding ring 101 includes two side walls 1011 and an upper wall 1012...

Abstract

The invention relates to an ancient irregular cold heading part which is characterized by comprising an irregular cold heading part body, wherein the irregular cold heading part body takes the shape of a column; an annular convex ring is arranged at the middle end of the irregular cold heading part body; the annular convex ring comprises two side walls and an upper wall; connecting parts of the two side walls and the upper wall are arc-shaped surfaces; connecting parts of the two side walls and the irregular cold heading part body are arc-shaped surfaces. The ancient irregular cold heading part has the beneficial effects that the annular convex rings and circular through holes are formed in the ancient irregular cold heading part, the connecting parts of the two side walls and the upper wall are arc-shaped surfaces, the connecting parts of the two side walls and the ancient irregular cold heading part are arc-shaped surfaces, the left end and the right end that are matched with the circular through holes at the edge of the irregular cold heading part body are inclined surfaces respectively. When being connected and mounted with a rubber part, a guide function is achieved, convenience in mounting is achieved, and meanwhile, the rubber part can be prevented from being scratched.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an ancient special-shaped cold heading part. Background technique [0002] In the existing automobile structure, it is necessary to use a large number of special-shaped cold heading parts, which are used in conjunction with iron parts or rubber parts. However, the structure layout of the existing special-shaped cold heading parts is unreasonable. , there is the problem of inconvenient installation; on the other hand, when the special-shaped cold heading parts are used in the car, because a large amount of heat energy will be generated in the car, the special-shaped parts will be damaged by a large amount of heat energy in the car, shortening the service life. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an ancient special-shaped cold heading which is convenient for installation and prolongs its servic...
