Problems solved by technology

[0002] With the development of my country's economy, people's living standards have also increased significantly. With the improvement of living standards, the society has relatively high requirements for metal processing, especially in the processing of forgings. Due to the length and The cross-sectional size is large. When forging is forged by general forging methods, the forging ratio is often greater than 3. Due to the large forging ratio, the transverse mechanical properties of the forging are reduced, resulting in anisotropy of the forging, which makes the stability of the forging Poor, so as to seriously affect the subsequent processing of forgings

Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below.

[0021] A stabilization treatment process for forging processing, the process of the stabilization treatment process is:

[0022] Step 1. Protective coating application: apply the forging to be forged before processing, apply the protective layer evenly on the surface of the forging before heating, and apply the protective layer to the forging before forging to reduce the surface of the forging during forging Carbonization occurs.

[0023] Step 2. Preheating before forging: place the forging in an electric furnace for preheating to 380°C, and then keep the heated forging for 2.5 hours. The preheating before forging can make the forging work at high temperature during forging. Shaping in less time makes forging easier.

[0024] Step 3, Forging Forging: After the metal is heated by forging equ...

Abstract

The invention aims at providing a stabilizing treatment technology of forged piece machining. The process of the stabilizing treatment technology comprises the steps of 1, protection coating smearing; 2, preheating before forging; 3, forged piece forging; 4, finish forging treatment; 5, preheating before finish turning, wherein a forged piece is placed in an electric furnace to be preheated to 560 DEG C-580 DEG C, and then the forged piece is discharged out of the furnace after being subjected to furnace cooling to 150 DEG C or below; and 6, finish turning treatment. Stabilizing treatment is carried out on stability of forged piece machining, and therefore the forging ratio is reduced, grains are refined, the mechanical property of the forged piece is improved, special shapes are reduced, the stability of the forged piece is improved, and the forging quality is improved.

Description

technical field [0001] The invention relates to the field of forging processing and auxiliary parts, in particular to the improvement of the stabilization processing method for metal forgings, and in particular to a stabilization processing process of forgings. Background technique [0002] With the development of my country's economy, people's living standards have also increased significantly. With the improvement of living standards, the society has relatively high requirements for metal processing, especially in the processing of forgings. Due to the length and The cross-sectional size is large. When forging is forged by general forging methods, the forging ratio is often greater than 3. Due to the large forging ratio, the transverse mechanical properties of the forging are reduced, resulting in anisotropy of the forging, which makes the stability of the forging Poor, so as to seriously affect the subsequent processing of forgings. [0003] Therefore, a stabilizing treatm...
