Abstract

The utility model relates to a nickel-metal hydride battery electrode burr punching machine, which belongs to the field of mechanical devices and comprises a hydraulic cylinder, a power motor, a controller, an upper die, a lower die and a lower die fixing support. Both of the upper die and the lower die are provided with a cavity matched with an electrode plate, and the side wall of each cavity is inclined. The nickel-metal hydride battery electrode burr punching machine modifies a device integrally punching the electrode plate into the machine punching three sides at the same time, can effectively remove burrs on edges of the electrode plate, avoids battery short circuit and internal micro short circuit, increases qualification rate of batteries, and leads qualification rate of battery assembly to be above 98%.

Description

Ni-MH battery pole piece burr stamping machine

Technical field

The utility model relates to a kind of Ni-MH battery pole piece burr stamping machine, belongs to the plant equipment field.

Background technology

The making of pole plate is earlier slurry to be coated in uniformly that (anodal base material is a nickel foam on the base material, base material of cathode is a steel band), and then the pole plate that scribbles slurry rolled the size that requires, at last the whole pole plate that rolls as requested size cut into the standard pole plate, it is the parts that scribble slurry that the standard pole plate of shearing has three limits, another side is a base material, three limits that scribble slurry are easy to occur burr when shearing, if handle bad, be wound into battery with such pole plate, pole plate is easy to diaphragm paper is pierced through, both positive and negative polarity is linked together, form internal short-circuit of battery, battery cancels, some burr causes the micro-short circuit of battery, for great hidden danger is buried in the use of battery.A lot of battery producers also used multiple diverse ways to remove burr, for example rolled-on method, rolling process, though some effects are arranged, not ideal.We carried out whole punching press to pole plate originally, and pressure is too big, and pole plate is with regard to easy deformation, the too little burr of not removing again of pressure.The utility model adopts three limit decompressors, increases pressure, has fundamentally solved this difficult problem.

Summary of the invention

The purpose of this utility model provides a kind of Ni-MH battery pole piece burr stamping machine that can effectively remove burr on the pole plate limit.

Technical solution: the utility model comprises: hydraulic jack, power motor, controller, mold, bed die, bed die fixed support, be equipped with the cavity that matches with pole piece on mold and the bed die, cavity wall is a sloped sidewall, and sloped sidewall becomes 10-45 ° with the cavity baseplane.

The utility model is that the original equipment that pole plate is carried out whole punching press is made into the punching press simultaneously of three limits, can effectively remove the burr on the pole plate limit, stops the inside battery micro-short circuit, improves the qualification rate of battery, and the qualification rate that makes the battery assembling is up to more than 98%.

The specific embodiment

The utility model comprises: hydraulic jack 1, power motor 3, controller 2, mold 4, bed die 5, bed die fixed support 8, be equipped with the cavity that matches with pole piece on mold and the bed die, mold cavity 6, bed die cavity 7, cavity bottom surface 10 degree of depth of mold cavity 6 and bed die cavity 7 are 0.3mm, and mold cavity wall 9 becomes 15-20 ° with bed die cavity wall 11 with the cavity baseplane.

During die-cut pole plate, want earlier pole piece to be placed in the bed die cavity 7, three limits of pole piece are placed on the cavity sloped sidewall, dotted portion 12 shown in Fig. 3 bed die 5 is the placement location on three limits of pole piece, and during operation, both hands touch the button simultaneously, cylinder drives mold 4 and presses down, punching press is carried out on three limits of pole piece, and the intact pole piece limit of punching press forms the figure of angular, as shown in Figure 5.

Claims

1. Ni-MH battery pole piece burr stamping machine, comprise: hydraulic jack, power motor, controller, mold, bed die, bed die fixed support, it is characterized in that be equipped with the cavity that matches with pole piece on mold and the bed die, cavity wall is a sloped sidewall.

2. Ni-MH battery pole piece burr stamping machine according to claim 1 is characterized in that sloped sidewall becomes 10-45 ° with the cavity baseplane.
