Rear axle housing set square stamping die

Abstract

The invention relates to a rear axle housing set square stamping die, and belongs to the technical field of automotive chassis system manufacturing. The rear axle housing set square stamping die is composed of a lower die base, a guide column, a guide sleeve, an upper die base, a lower die and an upper die. The lower die base and the upper die base are movably connected with the guide sleeve through the guide column, the lower die and a movable block c are fixedly installed on the lower die base, the upper die, a movable block a and a movable block b are fixedly installed on the upper die base, and a locating block a, a locating block b and a locating block c are installed on the lower die; a rubber column is installed on the lower die, the upper end of the rubber column makes contact with the movable block c, and the lower end of the rubber column makes contact with the lower die base; a rubber column is installed on the upper die, the upper end of the rubber column is in contact with the upper die base, and the lower end of the rubber column is in contact with the movable block a and the movable block b. The rear axle housing set square stamping die is reasonable in structural design, the die can be suitable for stamping set squares of various models, precision of shapes and dimensions of stamped set squares is high, the utilization rate of materials is high, the upper die and the lower die are long in service life, production cost is low, the production speed is high, and production and manufacturing cost of the set squares and the whole rear axle housing is greatly reduced.

Description

technical field [0001] The invention relates to a stamping die for a triangular plate of a rear axle housing, which belongs to the technical field of automobile chassis system manufacturing. Background technique [0002] With the rapid development of my country's automobile industry, the manufacturing technology of auto parts is changing with each passing day. The lightweight technology of automobiles is also the goal pursued by the automobile industry in various countries. Therefore, the stamped and welded rear axle housing assembly is widely used. With the development of the rear axle housing With the improvement of stamping and welding technology, the manufacturing accuracy of parts, especially the precision requirements of the rear axle housing triangle plate is becoming more and more stringent. Slow; the lower and upper molds are easy to collide during stamping, and the stamping parts of the lower and upper molds are easy to crack if there are about 10,000 stamping parts,...

[0002] With the rapid development of my country's automobile industry, the manufacturing technology of auto parts is changing with each passing day. The lightweight technology of automobiles is also the goal pursued by the automobile industry in various countries. Therefore, the stamped and welded rear axle housing assembly is widely used. With the development of the rear axle housing With the improvement of stamping and welding technology, the manufacturing accuracy of parts, especially the precision requirements of the rear axle housing triangle plate is becoming more and more stringent. Slow; the lower and upper molds are easy to collide during stamping, and the stamping parts of the lower and upper molds are easy to crack if there are about 10,000 stamping parts, and one type of triangular plate needs a set of corresponding stamping molds, which is poor in interchangeability, making the manufacturing cost of the stamping mold high and the service life of the mold short
