Rear axle housing stamping die

Abstract

The invention discloses a rear axle housing stamping die, and relates to the technical field of stamping die manufacturing. The rear axle housing stamping die comprises an upper die base and a lower die base, wherein the lower die base is fixed on a lower support plate through a die foot; a convex die is mounted at the lower end of the upper die base; a plurality of limiting holes are formed in the convex die; discharge rods and plug screws which stretch outside the lower end of the convex die are mounted inside the limiting holes; discharge springs are mounted between the plug screws and the discharge rods; a concave die and a concave die bottom plate which sleeves the concave die are mounted at the upper end of the lower die base; a concave die reinforcing plate is mounted above the concave die bottom plate through a support plate; baffles are mounted between two sides of the concave die and the concave die reinforcing plate; the lower ends of the baffles stretch into the concave die bottom plate; a discharge plate is inserted into the concave die; a plurality of guide holes are formed in the bottom of the discharge plate; a plurality of nitrogen springs are mounted on the lower support plate; the plunger rods of the nitrogen springs penetrate through the lower die base and stretch into the guide holes of the discharge plate. Compared with the prior art, the rear axle housing stamping die can form a rear axle housing in a stamping manner at once, thus alleviating the working intensity and improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of stamping die manufacturing, in particular to a stamping die used for processing rear axle housings of automobiles. Background technique [0002] Such as figure 1 The shown rear axle housing installed on a car includes a rear axle housing body 101, an arc-shaped concave cavity is arranged in the middle of the rear axle housing body 101, and upwardly bent side plates 102 are arranged on both sides. The plate 102 is provided with a concave arc surface. Because the overall size of the rear axle housing is large, the distance between the bottom surface of the arc-shaped concave cavity of the rear axle housing body and the upper end surface of the side plate 102 is far away. The mold is difficult to fix and the material is difficult to remove. Using the existing rear axle housing stamping die to process the rear axle housing cannot be stamped and formed at one time. It needs to be stamped twice. The workpiece ...
