Description
Technical field
The utility model relates to punching module, particularly relates to a kind of diel of making battery with grid.
Background technology
The effect one of grid in battery is support and the adhesion activity material that plays a part skeleton as the carrier of active material; The 2nd, play a part afflux, conflux and fail stream as the conductor of electric current; The 3rd, play a part to make electric current to be evenly distributed in the active material as the equal fluid of pole plate.Therefore, the formation of grid should possess following condition: the structure of (1) grid should help the strong bonded with active material, promptly by chemistry or mechanical effect, makes to exist good " adhesion " between grid and the active material.(2) the material requirements resistance of manufacturing grid is little, so that improve the conductive capability of pole plate and make the equally distributed ability of electric current.(3) structure of grid does not hinder expansion, the contraction of active material, pole plate is deformed, active material comes off and produce the be full of cracks or warpage.(4) grid material should have good corrosion stability, its structure and the tissue should be able to resist the charging or shelve during electrolyte (H
2SO
4) corrosion.(5) grid material should possess sufficient hardness and mechanical strength, with manufacturing, the processing request that satisfies pole plate.In order to maintain active material effectively, usually grid is made paliform with the different horizontal, vertical rib of cross sectional shape, making has bigger contact area between active material and the grid.Therefore the rib with grid designs carefully as far as possible, makes the distance between the rib bigger, could increase the capacity of active material so effectively.
The history that the production of lead-acid accumulator was passed by more than 100 year.In this process, the production Technology of battery is constantly progressive, and the manufacture level of plant equipment improves constantly, and has promoted product quality and production capacity to improve constantly.At present, the manufacture method of grid mainly contains casting, punching press, it is several to draw in the net, owing to be subjected to various condition restriction, all is to adopt casting method to make grid at present, and the grid rib that this method is made all compare slightly, can't cast than the grid of rib carefully.With drawing in the net the grid of manufactured, the lug of its grid is thinner, when high current load by the time, easily fusing causes whole grid to scrap.The technology production efficiency height of grid is drawn in the net in expansion, can realize that all grid and lug once form, and its shortcoming is that the grid of being processed lacks frame, as when being used for positive plate, its intensity and corrosion resistance have its limitation.The grid that punching type makes, have compact structure, rib is thinner, in light weight, quality is high advantage, but because stamping forming mould all is to adopt concavo-convex mould tangent mutually up and down, because of stereotype quality softness easily broken, easily extend and creep in the punching course, thus not only on the mould two side of rib groove be subjected to that the power of tangentially cutting is big, rib groove easy fracture, cause template to scrap, and the grid rib diameter of institute's punching press all compares slightly, can't process thinner grid rib.
Accompanying drawing 1 is depicted as the mould that existing punching type prepares battery grid, it is a kind of fixed form, this template is fixed in the mould cover during use, and the grid unit is formed by frame and by perpendicular, translot muscle, and each punching press can produce the grid that has 2 emissions groove holes, punching press is intact once, stereotype is continued forward to transmit, and when reaching mould locating slot place, carries out punching press next time, be that every transmission once can be finished a punching press, grid is promptly plastic by a punching press.Because existing battery requires the rib of grid tiny as far as possible,, but, in punching course, be damaged easily because the groove muscle is thinner so the groove muscle position of this mould is thinner.And can only punching press two arrange grids at every turn, and speed is slower, and production efficiency is not high.
The utility model content
Based on above-mentioned existing in prior technology problem, the utility model embodiment provides a kind of battery made from the diel of grid, can carry out punch forming battery grid twice, and in the punching course, can be because of the rib of module tiny the damage.
The utility model is achieved through the following technical solutions:
The utility model embodiment provides a kind of diel of making battery with grid, comprising:
The template body, described template body is provided with guide pillar hole, locating hole and die cavity, is provided with material-dropping hole in the described die cavity, is provided with the groove muscle around the material-dropping hole, and the groove muscle is provided with blade; Described material-dropping hole is divided into two groups, and two groups of material-dropping holes are provided with at interval, and the material-dropping hole in every group is a plurality of, between each material-dropping hole in every group also the space arrange and be provided with.
By above-mentioned embodiment of the present utility model as can be seen, in the utility model embodiment by two groups of blanking ports are set, and, setting is distributed in distance between each blanking port in every group, make the groove muscle between each blanking port be unlikely to tiny, utilize this mould in punching press grid process, can utilize two groups of blanking ports that grid is carried out twice punch forming.Thereby avoid one time punching molded tiny, the flimsy problem of mould of mould rib.Improved grid and used diel service life, improved the mechanical performance and the decay resistance of punching press grid, and then also improved the production efficiency of grid.
