Abstract

The invention discloses a forging process special for mask plate support alloy Invar 36. The forging process comprises the steps that after the surface of Invar36 alloy is cleaned with acetone, the cleaned Invar36 alloy is placed into a resistance furnace to be heated, the temperature in the resistance furnace is 950-980 DEG C, and heat preservation is conducted for 10-18 min; two-upsetting and two-drawing cogging forging is conducted, the first upsetting deformation is 30-35%, then first drawing is conducted, the drawing deformation is controlled to be 14-35%, and the Invar36 alloy is fed into a heating furnace at a temperature of 1100 DEG C for solution treatment; the second upsetting deformation is 50-60%, then second drawing is conducted, the drawing deformation is controlled to be 10-40%, and the Invar36 alloy is fed into the heating furnace at a temperature of 1050 DEG C for solution treatment, wherein the first solution treatment is conducted for 1.5 hours at the temperature of1100 DEG C, and the second solution treatment is conducted for 1 hour at the temperature of 1050 DEG C; and through two-upsetting and two-drawing cogging forging, the alloy is repeatedly forged, carbide in the alloy is better smashed, internal grains are finer through high-temperature calcination and repeated forging, and the strength, hardness, abrasion resistance, fatigue strength, toughness andthe like of channel steel are improved through quenching.

Description

technical field [0001] The invention relates to the technical field of mask brackets, in particular to a forging process dedicated to the alloy Invar36 of the mask bracket. Background technique [0002] At present, the manufacturing process of the existing mask plate holder is usually: die-casting, mechanical processing, injection molding of a plastic shell, mechanical processing of the shell, electroplating and assembly. Although the appearance quality of the mask plate bracket produced through the above manufacturing process meets the requirements for use, due to the characteristics of the die-casting production method, it will have mechanical performance defects such as pores, loose structure, poor roughness, and trachoma, which cannot meet the use requirements. , It is prone to breakage after long-term use. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a forging pr...
