Embodiment

[0025] refer to figure 1 , a production process of a hexagon head bolt in the present embodiment, comprising the following steps:

[0026] S1: According to the required size, cut the cylindrical blank of appropriate size;

[0027] S2: The cylindrical ingredients described in S1 are placed on the first station of the multi-station cold pier machine, and the first station of the multi-station cold pier machine cold-heads the upper end of the cylindrical ingredients into a preforming head The outer edge of the outer lower end of the preformed head is smooth and excessive, and at the same time, the first station of the multi-station cold pier machine cold-heads the lower end of the cylindrical ingredient into a screw part;

[0028] S3: The cylindrical ingredients described in S2 are moved to the second station of the multi-station cold pier machine, and the second station of the multi-station cold pier machine cold-heads the preformed head into a semi-formed head, The outer edge...

Abstract

The invention discloses a production process of a hexagonal head bolt. The production process comprises the following steps that S1, a cylindrical blank of the proper size is obtained through cuttingaccording to the required size; S2, the cylindrical blank in S1 is placed on a first station of a multi-station cold heading machine, the first station of the multi-station cold heading machine carries out cold heading forming on the upper end of the cylindrical blank to form a pre-formed head, the outer edge of the lower end of the outer side of the pre-formed head is in arc transition, and meanwhile the first station of the multi-station cold heading machine carries out cold heading forming on the lower end of the cylindrical blank to form a screw; and S3, the cylindrical blank in S2 is moved to a second station of the multi-station cold heading machine, and the second station of the multi-station cold heading machine carries out cold heading forming on the pre-formed head to form a semi-formed head. The production process is economical and practical, the head on the hexagonal head bolt can be automatically formed, after initial workpiece detection, head detection of the hexagonal head bolt can be omitted, then the work efficiency is improved, and the waste and detection cost is reduced.

Description

technical field [0001] The invention relates to the technical field of production technology of hexagon head bolts, in particular to a production technology of hexagon head bolts. Background technique [0002] Bolt is a tool that uses the physical and mathematical principles of oblique circular rotation and friction of the object to fasten the parts of the object step by step. Bolts are indispensable industrial necessities in daily life: such as cameras, glasses, clocks, electronics, etc. Very small bolts used; general bolts used in TV, electrical products, musical instruments, furniture, etc.; as for large bolts used in engineering, construction, bridges, etc., hexagon head bolts are a kind of bolts, and hexagon head bolts need to be installed during production. Production is carried out according to the trimming process of hexagon head bolts. In order to ensure the quality of hexagon head bolts, it is necessary to detect the height of the head on the hexagon head bolts. Ho...
