Abstract

The present invention relates to car door production process and apparatus, and is especially technological process and mold for binding edge of car frame edge. The outer door plate is bent and bound by means of the horizontal motion of slide block driven with the edge binding mold. The present invention has no need of replacing mold, short edge binding period, high production efficiency and high product precision.

Description

technical field [0001] The invention relates to a method and a device for manufacturing an automobile door, in particular to a process method and a hemming mold for an automobile door frame. Background technique [0002] At present, the hemming of known automobile door frames all adopts a single rocker arm wedge cam hemming die or a 6-bar mechanism hemming die. The working process of the single rocker arm wedge cam hemming die is: One side of the outer plate of the frame assembly is placed on the profiling tire, the upper die moves downward, the pressure plate presses the rear frame assembly tightly, the wedge pushes the cam to make the jackknife turn left along the fixed point and the outer plate of the rear frame The standing edge is folded into 45°, and as the upper die continues to move downward, the inclined wedge surface contacted by the cam terminates and passes through a transition zone. At this time, the spring pulls the folding knife back forcibly, letting go of th...
