Three-arm workpiece production process and the workpiece produced by this process

Abstract

The present invention relates to a three-arm workpiece production process and the workpiece produced by the process, which includes the following steps: S1, selecting raw materials, finding a raw material block whose volume and shape can meet the design requirements; S2, heating, using a heating device to quickly heat the raw material Carry out stable heating in a given temperature range; S3, rough forming, use a forming device such as a press to perform longitudinal forming operations on the heated raw material to make a rough embryo; S4, edge trimming, use a forming device such as a press to Trim the excess material around the rough billet, and cut out the second-stage billet with a three-arm shape; S5, punching, punching the designated position of the second-stage billet; S6, fine pressing, use a press, etc. The second-stage embryo is formed in the horizontal direction, and excess raw materials are cut off to obtain a refined embryo; S7, cooling, the refined embryo is cooled by air cooling until the refined embryo is cooled to room temperature. The invention has the effect of improving the dimensional stability of the punching position of the workpiece after punching.

Description

technical field [0001] The invention relates to the technical field of workpiece production, in particular to a three-arm workpiece production process and workpieces produced by the process. Background technique [0002] At present, with the prosperity of various projects, the types of workpieces (forgings, castings, etc.) that need to be used in various projects are becoming more and more complicated. Corresponding to the surge in demand, various workpiece forging and casting processes have emerged to meet these needs. [0003] For the existing technical solutions, please refer to the Chinese invention patent with the authorized notification number CN109482798B, which discloses a method for actively controlling the metal flow forming method of a drum-shaped forging with a thin web with a long arm and a thin web. It involves a long arm The forming method of thin-web cylindrical forgings includes: 1. Calculating the original blank required for the forging; 2. Upsetting the b...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: the current general process is generally punching after forming, but in the production process of customized workpieces or special-shaped workpieces, the deformation of the workpiece caused by punching will still cause gaps between the final workpieces. It is not uncommon to reduce the yield rate of workpieces due to ineffective matching, especially for small workpieces. When punching, the punching force of the punching machine will cause deformation and damage to the part of the workpiece that has just been formed.
