One-die-multi-part forging process of groove-shaped part

Abstract

The invention relates to a one-die-multi-part forging process of a groove-shaped part. The one-die-multi-part forging process comprises the following steps of 1, blanking process; 2, heating process;3, pre-forging process; 4, final forging process; 5, final forging process; 6, shot blasting process; and 7, sawing process. In the step 1, a metal disc saw is used for sawing round bar materials; inthe step 2, a medium-frequency heating furnace is used for carrying out heating treatment on the round bar materials cut off by the saw; in the step 3, upsetting treatment is carried out on the heatedround bar materials by an air hammer, the oxide skin on the surface of the round bar materials is removed, and the blank is upset until the sectional area is the same as the sectional area of a part;in the step 4, final forging treatment is carried out on the pre-forged blank by a hot die forging press, and the size of the part after the part is formed is consistent with the requirement of the drawing; in the step 5, the final forging part is subjected to edge cutting treatment by an open-type inclinable press; in the step 6, shot blasting is carried out on the cut part by using a crawler-type shot blasting machine; and in the step 7, the sawing process is carried out on the part subjected to shot blasting treatment through a band sawing machine, and finally the groove-shaped part is obtained. The production cost of the forging process is reduced, and the prepared groove-shaped part is high in strength and good in toughness.

Description

technical field [0001] The invention relates to the technical field of processing technology of grooved parts, in particular to a forging process of one die and multiple pieces of grooved parts. Background technique [0002] The trough-shaped parts are formed by plastic processing of metal and have a certain cross-sectional shape and size. The trough-shaped parts have various specifications and are widely used. Traditional trough-shaped parts are usually manufactured by hot drawing process, and only one trough-shaped part can be produced at a time, resulting in an increase in the production cost of the trough-shaped part, and the strength and toughness of the produced trough-shaped parts are low, which cannot meet the actual use requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, provide a kind of forging process of one die and multiple pieces of grooved pa...
