Abstract

The invention discloses a processing method for a rear supporting frame. The method comprises the following steps: A, cutting, wherein a raw material plate is cut into a material plate with the length being 1,500 mm and the width being 375+ / -1 mm by adopting a plate shearing machine; B, blanking, wherein the material plate obtained in the step A is mounted in a blanking die and die-cutting is performed; C, forming I, wherein the material plate obtained in the step B is mounted in a forming die I and subjected to punch forming by adopting a 100 T oil press; D, forming II, wherein the material plate obtained in the step C is mounted in a forming die II and subjected to punch forming by adopting a 315 T press machine; E, shaping, wherein the material plate obtained in the step D is mounted in a shaping die and subjected to shaping by adopting a 100 T press machine; F, punching, wherein the material plate obtained in the step E is mounted in a punching die and subjected to punching by adopting a 100 T press machine. With the adoption of the technical scheme, processing steps are simple, the finished product rate is increased, and the overall strength of the rear supporting frame is high.
