Abstract

The invention discloses a forging forming technology of a lifting hook. The technology includes the following steps that S1, round steel with a preset diameter is selected and is cut according to a preset length; S2, by means of an integral open die forging moulding bed and an open die forging hydraulic machine, the round steel cut in the S1 is drawn into variable-diameter round steel of the preset size; S3, a lifting hook bending machine is used for bending the variable-diameter round steel drawn in the S2 and manufacturing the variable-diameter round steel into a lifting hook blank meeting requirements; S4, by means of a die forging pressure machine and a forming forging die, the lifting hook blank in the S3 is forged into the lifting hook; S5, by means of the pressure machine and a trimming die, the lifting hook formed in the S4 is trimmed, and a finished lifting hook blank is obtained. By means of the forging forming technology, safety performance is greatly improved, production efficiency is greatly improved, manufactured drawn blanks are good in uniformity, the percent of pass is high, energy consumption is reduced, and efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of hook production, in particular to a forging forming process of a hook. Background technique

[0002] As a component with high safety requirements for hoisting machinery, the hook is indispensable. It is mainly forged with alloy steel. The traditional process, especially in the billet making process, mainly uses forging hammer and manual operation, which has a low degree of mechanization, high technical requirements for operators, low efficiency, and poor safety. At the same time, the uniformity of the workpiece Poor performance, low pass rate. For this reason, a kind of suspension hook forging forming process of the present invention well overcomes the shortcoming of traditional process. Contents of the invention

[0003] Based on the technical problems existing in the background technology, the present invention proposes a forging forming process of a hook.

[0004] The forging forming process of a ...
