Stamping waste negative pressure strong discharge device

Abstract

The invention discloses a punching waste negative pressure forceful drainage device which comprises a substrate, a support block, a bottom plate, a horn-shaped receiving hopper, a negative pressure assembly and a waste box, wherein the substrate is mounted on the bottom surface of a lower die, and a discharge channel which is matched with a discharge hole in the lower die is formed in the substrate; a plurality of support blocks are mounted between the substrate and the bottom plate and matched with the substrate and the bottom plate to form a cavity space; the horn-shaped receiving hopper is arranged on the bottom surface of the substrate and located in the cavity space, the big open end of the horn-shaped receiving hopper is matched with the discharge channel in the bottom surface of the substrate, and a plurality of forceful magnets are embedded into the end surface of the big open end of the horn-shaped receiving hopper. According to the punching waste negative pressure forceful drainage device, the structure is simple, the design is reasonable, during working, the magnets are used for providing certain down pull, strong wind produced by the negative pressure assembly blows waste into the waste box, punching shear waste of each time falls downward by suction, and the phenomenon that the die explodes and a punching pin is broken to affect the production due to the fact that the die is blocked by overlapping of a plurality of waste due to production oil cannot occur during production.

Description

technical field [0001] The invention relates to a discharge device for stamping dies, in particular to a negative pressure forced discharge device for stamping waste. Background technique [0002] On some stamping dies, especially when there are many small holes in the production of metal materials, small waste materials will often be blocked together and cannot fall down, so that the explosion mold production stops. However, due to the small size of the punch, there is no way to add a stripping thimble. At the same time, it is necessary to add punching oil and the viscosity of the metal material itself during production, so small scraps are easy to overlap. If the waste cannot be discharged in time, blocking the die will cause the die to explode, and the upper punch will break when it is punched down. When the above situation occurs, if figure 1 As shown, after the waste is blocked, the mold will explode and the punching pin will be broken, which will cause equipment dama...

Problems solved by technology

However, due to the small size of the punch, there is no way to add a stripping thimble. At the same time, it is necessary to add punching oil and the viscosity of the metal material itself during production, so small scraps are easy to overlap.

If the waste cannot be discharged in time, the die will explode if it is blocked, and the upper punch will break when it is punched down.

When the above situation occurs, if figure 1 As shown, after the waste is blocked, the mold will burst and the punching pin will be broken, which will cause equipment damage and affect production
