Develop of drawing die for rear door inner plate with piercing switch
Taking the rear door inner plate of a car as the research object,a pneumatic side pierc-ing switching mechanism was designed to meet the needs of side piercing switching of part in the process of die development.Using self-made inclined wedge could realize piercing and switching of multiple holes,and solve the problem of uneven material flow and eliminate the wrinkling de-fect of the formed parts.Practice verified that the switching process of the pneumatic side piercing switching mechanism was stable,and it was easy to detect and maintain,and economy.
