The forging of flat welding flange

　　The forging of flat welding flange is forged according to the movement mode of forging die and can be divided into rolling, pendulum swaging, swaging, wedge rolling, rolling ring and skew rolling, etc., swing rolling, pendulum swaging and ring rolling. Precision forging To improve the utilization of materials Roll forging and cross-rolling can be used as a slender material before the process of processing, it is difficult to guarantee the accuracy of the die so the direction of movement and swaging process with computer control can be used on the lower Forging force to obtain the shape of complex, high precision products.
