Bending and shaping die for automobile upper door hinge brackets

Abstract

The invention provides a bending and shaping die for automobile upper door hinge brackets. The bending and shaping die comprises an upper die structure and a lower die structure. The upper die structure comprises an upper die plate, an upper padding plate is mounted under the upper die plate, and upper padding feet are mounted on the upper die plate. The lower die structure comprises a lower die plate, a lower padding plate is mounted on the lower die plate, a mounting plate is mounted under the lower die plate through lower padding feet, and die assembling is performed through a sliding guide post component between the upper die plate and the lower die plate. The bending and shaping die is characterized in that a shaping male die is mounted under the upper padding plate, a female die frame is mounted on the lower padding plate, an ejecting plate is embedded in the female die frame, a positioning nail is vertically mounted in the ejecting block and penetrates the ejecting block from bottom to top, an ejecting mechanism is mounted under the ejecting block and penetrates the lower die plate, the lower padding plate from bottom to top to be connected with the bottom surface of the ejecting block, and a limiting hole is formed in the position of the shaping male die and directly facing the positioning nail. By the bending and shaping die, the problem about inaccurate positioning of a workpiece in processing of simple punching dies can be solved, processing quality can be improved, and rejection rate can be lowered.

Description

technical field [0001] The invention relates to the technical field of processing auto parts, in particular to a bending mold for a bracket on an auto door hinge. Background technique [0002] An upper bracket on an automobile door hinge, the structure of which is shown in figure 1 , figure 2 , its horizontal overall is in the shape of a "several", usually the door hinge brackets on the left and right sides of the car have a symmetrical structure. Carry out the punching process of positioning hole 25, see image 3 , and then perform two bending moldings, then carry out side punching processing, and finally cut off the central connecting material part and complete the punching processing of the bracket plane at the same time. Since the hinge bracket is a thin-walled part and the bending profile is relatively simple, in the past The two-time bending forming is mostly carried out by traditional simple stamping dies. The punch and die of the simple stamping dies are all inte...
