Control of forging crack of external fixed plate
This paper analyzes the causes of crack defects in the external parts of the important parts of the train coupler bumper after forging. By shortening the forging and pressure forming time, increasing the forming temperature, improving the surface quality of the forging, timely filling and seepage after pressure forming Normalizing heat treatment before carbon reduces and eliminates surface tensile stress after forging and pressure forming, reduces the tendency of cracking on the surface of the part, effectively suppresses the generation of forging cracks, and improves product quality.
