Bending forming process for automobile parts

The invention discloses a bending forming process for automobile parts, relates to the technical field of automobile part production processes, and aims to solve the problems that in the existing bending forming process, a mold is prone to being damaged by material pulling, and springback is prone to occurring after bending. In the step 1, the surface of the stamped accessory is polished; 2, groove pressing treatment is conducted before bending, and the feed number and the feed depth are set according to the thickness of the accessory; 3, the bending process hole is cut along the bending line, and the depth size of the bending process hole is calculated according to the actual thickness of the accessory; 4, the lower dead center of a sliding block of the bending machine and a straight plate are adjusted, and the bending machine conducts bending treatment on the accessory after being adjusted; 5, the bent accessory is subjected to decontamination and phosphating treatment; 6, the surface of the accessory is sp
