Technical Field

The invention belongs to the field of battery production, and particularly relates to a shearing device for drawing a shell.

Background

Drawing, also called drawing, stretching, calendering and the like, refers to a mechanical processing technology which utilizes a die to punch a flat blank with a certain shape obtained after punching into various open hollow parts or reduce the diameter of the open hollow blank and increase the height of the open hollow blank.

Disclosure of Invention

In order to solve the problems in the processing process of the battery shell, the invention designs a novel deep-drawing shell shearing device which structurally comprises an upper die and a lower die; the upper die comprises a shearing die handle, a shearing fixing seat, a shearing punch and a shearing chip, and the components are fixed in sequence from top to bottom; a return steel ball and a return spring are arranged in the shearing chip, one end of the return spring is fixed with the return steel ball, the other end of the return spring is fixed with a nut part of a screw, the other end of the screw extends out of the lower surface of the shearing chip, the upper half part of the return steel ball is exposed out of the upper surface of the shearing chip, the lower surface of the shearing punch is provided with a groove matched with the return steel ball, and the shearing punch and the shearing chip are fixed through a bolt and a gasket; the lower die comprises: upper part: the shearing die comprises a shearing pressing plate, a shearing female die and a shearing ejector rod from outside to inside, wherein the shearing ejector rod comprises an upper ejector rod and a lower ejector rod, the section of the lower ejector rod is larger than that of the upper ejector rod, the upper surface of the upper ejector rod is the same as the periphery of the lower surface of the shearing chip, and a gap is formed between the shearing female die and the upper ejector rod; the middle part: the shearing die holder, the guide plate, the movable seat and the striking rod are arranged in the outer die holder and the inner die holder, one end of the striking rod is fixed with the lower ejector rod, and the other end of the striking rod is fixed with the spring cover; the lower part: the spring cover comprises an ejector rod, a spring sleeve fixed below the ejector rod, a spring fixed in the spring sleeve, and a bottom plate fixed at the bottom of the spring sleeve, wherein one end of the spring is fixed with the spring cover, and the other end of the spring is fixed with the bottom plate.

Preferably, four ejector pins are fixed below the shearing fixing seat, and the lower ends of the ejector pins and the lower surface of the shearing punch are in the same plane.

Preferably, the cutting die holder is divided into an upper layer die holder, a middle layer die holder and a lower layer die holder, wherein the section of the lower layer die holder is larger than that of the other two layers.

Preferably, the waist of the spring sleeve is provided with a lower shearing movable plate.

Preferably, the lower shearing movable plate, the lower layer die holder and the shearing press plate are provided with a plurality of mounting holes.

When the invention is produced, the lower die is fixed on a processing table, the upper die is fixed on stamping equipment, when in deep drawing, the shearing chip is pressed downwards, the shearing female die moves downwards, the existence of the ejector pin controls the maximum stroke of the deep drawing to be at the required depth, the upper die moves upwards after the deep drawing is finished, the deep drawing shell is rebounded to the table by the spring, and the return spring and the return steel ball are combined with the screw to ensure that the shell cannot be attached to the shearing chip.
