Abstract
The utility model discloses a punching-type grid, which comprises a frame, tabs, vertical ribs and transverse ribs. The punching-type grid is characterized in that the cross section of each vertical rib is larger than that of each transverse rib, and the thickness of the vertical ribs is higher than the height thereof. By optimizing the grid structure, voltage drop can be reduced, active substances can be fully utilized and the discharge performance of the lead accumulator can be improved; the surface of the grid is concaved or protruded through a stamping or rolling method, so that the stress caused by the continuous casting and rolling-stamping processing process on the grid can be eliminated, so as to prevent the grid from being deformed in future use; and the surface of the grid is protruded or concaved and the roughness of the surface of the grid is increased so as to improve the touch area and the combination power between the transverse ribs and the active substances (such as lead plaster), thereby further improving the comprehensive performance of the lead accumulator.
Description
Technical field
The utility model relates to a kind of grid for lead accumulator electrode, relates in particular to a kind of punched holes type grid.
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, make balanced current distribution on active material.Grid structure mainly comprises: frame, lug, perpendicular rib, the cross rib that intersects with perpendicular rib.The Main Function 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 for anode plate grid, to keep the main shape of pole plate; Electric action, particularly both sides and upper side frame are also arranged certainly.Perpendicular rib mainly is 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 structure that tradition grid manufacturing technology obtains, perpendicular, cross rib bar evenly distributes, and makes the distributed pole of electric current unbalanced, have larger voltage drop loss in the lug district, and the active material utilization of pole plate bottom is not high.Another shortcoming of this configuration is that cross rib is overstocked, and the sectional area of cross rib is close with perpendicular rib.The lead plaster that contains of pole plate was reduced, namely reduced the mass ratio of lead plaster and grid, be unfavorable for again that electric current transmitted to the lug district along perpendicular rib.
The grid manufacturing is a key technology during lead accumulator is produced, and adopts the continuous lead of continuous strip-casting machine production or lead alloy band, and produces the new technology that the continuous punching grid is the manufacturing of lead plumbate battery grid in conjunction with the metal stamping technology.Paid close attention to by increasing battery manufacturers in recent years.The base material of lead accumulator continuous punching grid is lead or the lead alloy band of continuous casting and rolling or continuous casting-roll-in, and plumbous belt surface is very smooth, so the grid surface of continuous punching is also very smooth.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 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 hours timeliness, internal stress also is difficult to eliminate fully.But in the uncoiling of lead band and through behind the continuous punching, internal stress can be discharged.Cause the easy flexural deformation of grid of continuous punching, affect follow-up grid rolling and be coated with continuously cream and grid such as cuts at the operation.
The utility model content
The utility model purpose provides the punched holes type grid, overcomes the defective of prior art, optimizes grid structure; Not only increase the surface roughness of grid but also eliminated the internal stress of grid, avoided the plate buckling and the deformation that in from now on use procedure, produce because the machining stress of grid fails to discharge; Improve the adhesion of active material (lead plaster) and grid; Increase the cream ability of holding of grid, and then improve the combination property of lead accumulator.
For achieving the above object, the utility model by the following technical solutions.The punched holes type grid comprises frame, lug, perpendicular rib, cross rib, it is characterized in that: the sectional area of perpendicular rib is greater than cross rib, and the thickness of cross rib is greater than its height.Cross rib thickness described in the utility model refers to when the grid horizontal positioned spacing between the rear and front end, cross rib horizontal cross-section; Cross rib height described in the utility model refers to when the grid horizontal positioned, and the cross rib vertical section is the spacing between the two ends up and down.
Further, perpendicular rib be by the lug district to the diagonal rib of radiation radially, the spacing between the lug district cross rib is less than away from the spacing between the lug district cross rib.
Further, the grid surface forms projection and depression by punching press.
Further, the grid surface forms projection and depression by roll-in.
Further, the grid surface increases roughness by sandblast.
Further, processing is combined by punching press, roll-in in grid surface with sandblast, forms protruding and caves in, and increases simultaneously roughness.
The beneficial effects of the utility model: by optimizing grid structure, can reduce voltage drop, take full advantage of active material, improve the lead accumulator discharge performance; By punching press or roll-in method, make the grid surface form projection and depression, can eliminate the stress that grid produces in continuous casting and rolling Punching Process, avoid deforming in the grid use procedure afterwards; Make the grid surface form projection and cave in and increase the grid surface roughness, can increase contact area and the adhesion of cross rib and active material (lead plaster), and then improve the combination property of lead accumulator.
