Problems solved by technology
Elastic unloading can effectively solve the deformation problem, but elastic components are prone to failure and unreliable unloading; rigid unloading, although unloading is reliable, but the deformation is serious
It can be seen from the above that the rigid unloading and elastic unloading structures have their own advantages and disadvantages, that is, there are different disadvantages while maintaining their respective advantages. How to avoid the disadvantages of the two and take advantage of the advantages of the two has been explored by those skilled in the art direction

Embodiment Construction
[0016] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0017] The present invention proposes a floating rigid discharge structure based on a rigid discharge structure and an elastic discharge structure. The specific structure can be seen figure 1 As can be seen from the figure, the floating rigid discharge structure of the present invention includes a male mold 1, a male mold fixing plate 2, a female mold 3, a female mold fixing plate 4, an upper mold base 5 and a lower mold base 6. The convex mold 1 is installed on the convex mold fixing plate 2, and the convex mold fixing plate 2 is connected with the upper mold base 5 through the convex mold backing plate 7. The concave mold 3 is installed on the concave mold fixing plate 4, and the concave mold fixing plate 4 is connected with the lower mold base 6. The die fixing plate 4 and the die 3, and the die fixing plate 4 and the lower die s...

The invention discloses a floating type rigid discharge structure. The floating type rigid discharge structure comprises a convex die, a convex die fixing plate, a concave die, a concave die fixing plate, an upper die holder and a lower die holder, wherein a discharge plate is arranged above the concave die fixing plate; discharge plate connecting bolts connect the discharge plate with the concave die fixing plate in a floating manner under the action of discharge plate return springs; a pressing plate is arranged above the discharge plate; pressing plate connecting bolts sequentially penetrate through the pressing plate, the convex die fixing plate and a convex die base plate from bottom to top to be connected with the upper die holder; and compressed pressing plate thrust springs sleeve the pressing plate connecting bolts between the pressing plate and the convex mold fixing plate. According to the floating type rigid discharge structure, rigid discharge is achieved under action of elastic force of the springs and spacing of the bolts, respective disadvantages of a conventional rigid discharge structure and a conventional elastic discharge structure are ingeniously avoided, and advantages of the conventional rigid discharge structure and the conventional elastic discharge structure are absorbed.
Description
Technical field [0001] The invention relates to a punching die, in particular to a floating rigid discharge structure on the punching die, and belongs to stamping technology. Background technique [0002] Stamping die is a special process equipment for processing materials into parts in cold stamping processing. After one stamping is completed, a formed part will be stamped out. After the mold is opened up, it needs to be unloaded to separate the workpiece from the punch so that the workpiece remains. Existing mold discharge structures mainly include rigid discharge and elastic discharge structures. The unloading board is fixed and it is rigid unloading. The discharge plate is pushed by the elastic element, which is elastic discharge. Among them, the elastic discharge structure has a small discharge force and has an edge-holding effect, and the rigid discharge structure has a large unloading force but has no edge-holding effect. Elastic discharge can effectively solve the de...
