Technical Field

The utility model belongs to the technical field of the stamping die technique and specifically relates to a big negative angle shaping structure in little space.

Background

In the prior art, the large negative angle bending forming is usually completed by two sliding blocks, and the problems of high mold cost, low production efficiency, high labor and punch cost and the like exist.

Accordingly, the prior art is subject to improvements and enhancements.

Disclosure of Invention

To the weak point that exists among the prior art, the utility model aims at providing a big negative angle shaping structure in little space that mould is with low costs, production efficiency is high, manual work and punch press cost are few.

In order to achieve the above object, the utility model adopts the following technical scheme:

a small-space large-negative-angle forming structure comprises an upper die and a lower die, wherein the upper die comprises an upper die base, a pressure plate and a forming sliding block, a nitrogen spring is arranged between the upper die base and the pressure plate, the forming sliding block is arranged on a left inclined plane at the lower part of a wedge base, and the wedge base is fixed on the upper die base; the lower mould includes from the top down lower mould shaping fixed block, lower bolster and die holder that sets gradually, lower mould shaping fixed block include with press flitch matched with high platform and with shaping slider matched with low platform, rotate between high platform and the low platform and install lower mould shaping piece, lower mould shaping piece have one with the shaping head matched with breach that shaping slider lower extreme left part extends, one side of breach is the shaping end, the shaping end with be equipped with the extension spring between the high platform, the opposite side is the atress end, the top of atress end set up with the free end of shaping slider matched with clamp plate, the link of clamp plate rotates to be installed low bench, lower bolster, die holder pass through guide pillar guide pin bushing with the upper die base is connected.

Preferably, a limiting plate is fixed on the right inclined surface at the lower part of the inclined wedge base.

Compared with the prior art, the beneficial effects of the utility model are that:

due to the adoption of the structural design, the large negative angle forming can be completed only by one forming slide block, the mold cost is reduced, the production efficiency is improved, and the labor and punch cost is reduced.
