Abstract
The utility model relates to a decollation bolt for fastening an automobile. A middle structure of the bolt is a cylinder with a chute on the lateral face. The cylinder is smooth in surface and uniform in thickness, the upper end of the cylinder is connected with a flange face of a decollation bolt head, and the lower end of the cylinder is connected with a flange face of a decollation bolt tail. By means of the mold cold extrusion molding process, the decollation bolt for fastening the automobile not only remarkably saves raw materials for manufacturing the bolt, but also simplifies production process. Due to the fact that the decollation bolt is formed by one step without the need of turning, products are more stable, bolt torsion is equal, and product quality is improved.
Description
Technical field
The utility model relates to fastener areas, particularly relates to a kind of fastening decollation bolt of automobile that is used for.
Background technique
The central structure of the decollation bolt that uses at present; Be that position between decollation bolt head and the afterbody generally adopts turning (recessing) technology or side cut formation technique to make; But above process materials waste is many; Complex process causes cost of production to rise, and factors such as the potential risk of personnel operation error and tool wear can cause bolts assemblies torsion unstable during turning simultaneously, and the control of product quality difficulty is increased.
Summary of the invention
The utility model technical problem to be solved provides a kind of fastening decollation bolt of automobile that is used for, and can obviously save material, and reduces production costs, and improves the quality of products.
The utility model solves the technological scheme that its technical problem adopted: a kind of fastening decollation bolt of automobile that is used for is provided, comprises the bolt middle part, described bolt central structure is the cylindrical body that the side has skewed slot.
Described periphery is smooth, even thickness.
Upper end, described bolt middle part links to each other with the flanged surface of described decollation bolt head, and the flanged surface of lower end and described decollation bolt afterbody joins.
Beneficial effect
Owing to adopted above-mentioned technological scheme, the utility model compared with prior art has following advantage and good effect: the utility model is through the mold cold extrusion forming process; Manufacture the central structure of existing decollation bolt, thereby both obviously practiced thrift the raw material of making bolt, simplified production technology again; Because cold heading technique carries out once-through; Without turning, make both sides bolt torsion stable, improved quality of product.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The mode of execution of the utility model relates to a kind of fastening decollation bolt of automobile that is used for; As shown in Figure 1; Its bolt middle part 1 structure is the cylindrical body that the side has skewed slot, and described periphery is smooth, even thickness; The flanged surface of described bolt 1 upper end, middle part and decollation bolt head links to each other, and the flanged surface of lower end and bolt tail joins.
Claims (2)
