Metal shrapnel stamping die

Abstract

The invention relates to the field of dies, in particular to a metal elastic sheet punching die. The metal elastic sheet punching die comprises a base, a die plate, an extending plate, a hydraulic rod, a lower die, a connecting shaft, a first gear, a fixed shaft, a supporting plate, a connecting plate, a first spring, a cross shaft, a second gear, a rocking handle, a guide rod, a pull rope, a sliding plate, a second spring, a pressing plate, a guide plate, a vertical rod, a third spring, a sleeve rod, a bottom plate, a first upper die, a second upper die, a connecting rod, a top plate, a toothed plate, a vertical plate, a gear shaft, a belt wheel, a belt and a motor. According to the metal elastic sheet punching die, steel sheets with different shapes can be conveniently supported throughrotation of the dies so that the steel sheets can be machined into different types of metal elastic sheets, and the applicability of the punching die is improved; the positions of the two dies are adjusted through the movement of the bottom plate, and then the metal elastic sheets with different types can be conveniently machined; and the steel sheets can be limited conveniently through rotation of the pressing plate, so that the problem that the machining quality is influenced due to the fact that the positions of the steel sheets are deviated during punching machining is avoided.

Description

technical field [0001] The invention relates to the field of molds, in particular to a stamping mold for metal shrapnel. Background technique [0002] The metal shrapnel is made of ultra-thin and ultra-thick stainless steel 301 or 304 materials. The metal shrapnel is an important part of the switch. The metal shrapnel is mainly used in membrane switches, contact switches, PCB boards, FPC boards, medical equipment, etc. In the product, the working principle of the metal shrapnel: the metal shrapnel on the membrane button is located on the conductive part of the PCB. When pressed, the center point of the shrapnel is concave and touches the circuit on the PCB, thereby forming a loop, and the current passes through. The product can work normally, the general conventional metal shrapnel, the diameter is from 3 mm to 20 mm. [0003] The current metal shrapnel is used in switches, medical devices, etc. by utilizing the elastic properties of the metal sheet. The metal shrapnel is m...

AI Technical Summary

Problems solved by technology

[0003] The current metal shrapnel is used in switches, medical devices, etc. by utilizing the elastic properties of the metal sheet. The metal shrapnel is made by stamping. , for the stamping die of metal shrapnel, since the usual stamping die can only be processed into one shape of metal shrapnel, the applicability of the stamping die is reduced, which is not conducive to processing two different types of shrapnel; and different When metal shrapnel is used, it is not conducive to the adjustment of the mold position, which increases the difficulty of operation and reduces the convenience of operation; and when stamping, it is not conducive to the fixation of the steel sheet to be stamped, and it is easy to cause deviation of the steel sheet to be stamped during processing. Shift, reducing the processing quality
