Zincium tablet for 9 volt layered dry cell battery and blanking equipment and process

Abstract

The invention discloses a zinc flake for a 9V stacked dry battery and a blanking equipment and a process thereof. The zinc flake is a rectangle tabular body with four corners as diamond edges, vertex angles of adjacent four zinc flake form a diamond hole. The blanking device for preparing the zinc flake comprises a zinc flake mould. The section shape of the end part of the zinc flak mould is a diamond shape. The invention employs a stepping feeding blanking process, that is to rotate a zinc flake feeding seat, push a continuous zinc plate into the zinc mould of a blanking device, pinching parallely disposed diamond holes on the continuous zinc plate by a punch, then cutting the continuous zinc plate along a diagonal of the diamond holes into the rectangle plate with four corner as diamondedges. The invention eliminates the space between the adjacent zinc slice lateral direction and the vertical direction, thus saves the zinc plate material, and reduces the production cost. The produced zinc flake has stable quality and can guarantee the demand to the stacked battery quality.

Description

technical field [0001] The invention relates to a battery zinc sheet, punching equipment and a process, in particular to a zinc sheet used in a nine-volt laminated dry battery and the punching equipment and process for production. Background technique [0002] In a nine-volt stacked battery, each unit cell of the battery pack has a battery such as figure 1 The zinc sheet shown is to meet the needs of the chemical reaction of the battery. The zinc sheet is a rectangular sheet with four vertices that transition smoothly. and starch paper layers. It is usually made by punching and cutting continuous zinc sheets in a step-by-step drawing method. Such as image 3 As shown, it is a punching equipment for punching and manufacturing zinc flakes in the prior art. The continuous zinc plate is wound on the rotating shaft of the zinc plate seat, and its free end is wound on the rotating shaft of the scrap seat after passing through the punching equipment. The blanking equipment incl...

AI Technical Summary

Problems solved by technology

In order to ensure that the positions of the two punched zinc sheets do not overlap, it is necessary to control the step interval of the continuous zinc sheet on the punching equipment so that the interval between the two punched zinc sheets is 0.8-1.2mm, such as figure 2 As shown, it is a schematic diagram of zinc plate waste after blanking in the existing process, and this part of zinc plate will be wasted as side waste
