Description
Technical field
The present invention relates to a kind of lead accumulator with grid and manufacturing approach and equipment, relate in particular to a kind of lead accumulator with punched holes type grid and manufacturing approach and equipment.
Background technology
Grid is the significant components of lead accumulator, and its effect is: support active material, serve as the carrier of active material; The conduction and compile electric current, electric current is evenly distributed on the active material.The grid structure mainly comprises: frame, lug, perpendicular rib, the cross rib that intersects with perpendicular rib.The main effect of frame is to prevent that grid is out of shape in being coated with the cream process, tears; Still have metal to keep when also requiring end-of-life, to keep the main shape of pole plate for anode plate grid; Electric action, particularly both sides and upper side frame are also arranged certainly.Perpendicular rib mainly is a delivered current.The cross rib major function is and erects rib and be connected, in order to support active material.Lug is in order to weld the parallel connection of pole plate of the same name.
The grid manufacturing is a key technology during lead accumulator is produced, and adopts continuous lead of continuous strip-casting machine production or lead alloy band, and the continuous punching press grid of bond stamping technology production is the new technology that the lead plumbate battery grid is made.Paid close attention to by increasing battery manufacturers in recent years.The base material of the continuous punching press grid of lead accumulator is the lead or the lead alloy band of continuous casting and rolling or continuous casting-roll-in, and plumbous belt surface is very smooth, and therefore the grid surface of punching press is also very smooth continuously.Follow-up being coated with in the cream process, the adhesion of grid and lead plaster is less, the cream phenomenon often occurs taking off, and battery performance is relatively poor, and the life-span is shorter, has had a strong impact on the large-scale promotion application of continuous punching press grid.
The stress that lead alloy band produces in the course of processing needs to discharge, and the lead band of coiling is very tight, even through 24 little time aging, internal stress also is difficult to eliminate fully.But in the uncoiling of lead band and through after the continuous punching press, internal stress can obtain discharging.Cause the easy flexural deformation of grid of continuous punching press, influence follow-up grid rolling and be coated with cream continuously and grid such as cuts at operation.
Summary of the invention
The objective of the invention is: a kind of punched holes type grid is provided, and the stress of grid in the course of processing is able to eliminate, and avoids deforming in the grid use afterwards; The grid surface has suitable roughness, increases the contact area and the adhesion of grid surface and electrode active material (lead plaster), increases and holds the cream amount, avoids lead plaster to come off.
For realizing this purpose, adopt following technical scheme.The punched holes type grid comprises frame, lug, perpendicular rib, cross rib, it is characterized in that: the protruding and depression that the grid surface has roll-in to form.Further, the grid surface increases roughness through sandblast.Further, there is the protruding and depression that is stamped to form on the grid surface.
Another object of the present invention is: the manufacturing approach that aforementioned punched holes type grid is provided.May further comprise the steps: rolling good lead band or lead alloy band are sent into rolling device by pay-off; Extrude protruding and depression by rolling device at lead band or lead alloy band surface roll; The decorative pattern and the texture of running roller can be according to the convenient adjustment of design demand up and down for rolling device, and the roll-in process also is simultaneously that stress is eliminated process; Lead band after the roll-in or lead alloy band get into decompressor, by the mould and the step that design in advance lead band or lead alloy band are struck out required structure by decompressor, and diel and step can be adjusted according to design demand flexibly; The grid that stamps out gets into subsequent handling.Further, the grid that stamps out carried out blasting treatment before getting into subsequent handling.Further, in decompressor, add a cover embossing mould and an embossing step, make the grid surface stamp out convexity and depression.
Another object of the present invention is: the manufacturing equipment that aforementioned punched holes type grid is provided.Comprise pay-off, rolling good lead band or lead alloy band are sent into rolling device; Rolling device goes out convexity and depression with lead band or lead alloy band roll-in, eliminates stress simultaneously; Decompressor and diel strike out required structure with lead band after the roll-in or lead alloy band according to the step that designs in advance; Control device, each assembly of control grid manufacturing equipment makes each assembly synergistic work.Further, also comprise sand blasting unit, the grid that stamps out is carried out blasting treatment, increase its surface roughness.Further, decompressor also comprises knurling mould, makes the grid surface stamp out convexity and depression.
The invention has the beneficial effects as follows: grid forms convexity and depression through roll-in, both can eliminate the stress in the grid course of processing, can increase the grid surface again and hold the adhesion between cream amount and grid and the lead plaster.On this basis grid is carried out blasting treatment, can increase the grid surface roughness, further improve the adhesion between grid and the lead plaster.Punching press makes its surface form protruding and depression to grid on this basis, can further strengthen to eliminate stress, increase the effect of holding cream amount and adhesion.
