Description
Technical field
The invention belongs to battery and manufacture field, the manufacturing process and the manufacture that relate to a kind of lead acid accumulator plate grid are establishedStandby.
Background technology
Grid plays a part carrying active material and conduction in polar plate of lead acid storage battery, and the gauge of grid determinesThe amount of its active material that can carry, it is strong with the combination of the active material that carries that the planform of grid affects gridDegree. At present, grid for lead-acid storage batteries is mostly plane grid, and so-called plane grid is the inner rib thickness of grid and plateGrid thickness is equal or roughly equal, and whole grid is porous flat plate shape, and the grid of this plane makes activity attached to itMaterial is divided into some approximate independently unit by rib and frame, shrink because active material is dry and use procedure in curvedThe reasons such as song, vibration, the bond strength of active material and grid is lower, makes thereby easily cause coming off of active material to affect batteryUse the life-span. In addition, because the full-filling thickness of active material can only exceed 0.1～0.2mm of grid face, therefore plane grid is livedProperty material full-filling amount less, need to increase slab lattice thickness, the increasing of slab lattice thickness and weight if wish increases active material full-filling amountAdd and can make the full-filling ratio of active material decline, the method for this increase active material can not meet high-performance power type or accumulation of energyThe demand that type lead-acid accumulator is produced.
In order to increase full-filling ratio, people are studying a kind of Curved-surface grid, and attempting will on the basis of plane gridGrid flexural deformation forms curved face type grid, and the integral thickness of curved face type grid depends on bending maximum height, thereby curved surfaceType slab lattice thickness is greater than rib thickness, and under the constant prerequisite of grid dimensional weight, its active material full-filling amount will be far longer thanPlane grid, and due to the curved shape of grid make active material can by sweep be interconnected form one wholeBody, has strengthened the bond strength of active material and grid, and curved face type grid is to increase active material full-filling ratio and ensure activeThe mode of optimizing structure of the one between material and grid with good bond strength.
At present, curved face type grid is a research direction, and the manufacturing equipment of existing plane grid can only complete flatThe manufacture of face template grid, it can not complete the manufacture of curved face type grid, there is no at present the manufacturing equipment of curved face type grid. If adoptWhen punching mode is manufactured Curved-surface grid, the stress influence being out of shape by bending in forming process can change original size of grid,Although can be before brake forming pre-compensation, because of interrelated between flexural deformation degree and grid precompensation size, need anti-Multiple experiment can be determined its amount of pre-compensation, more greatly and extremely difficult control of its scale error; In addition, battery manufacture is at present to lowConsumption, efficient future development, the making of grid has become the main flow of current grid development, continuously the brake forming process of grid continuouslyIn, adjacent twice brake forming meeting produces mutually to be interfered, and makes in type part again produce interference deformation, affects molded portionThe geomery dividing. It is therefore, a kind of that rationally Curved-surface grid manufacturing process and equipment become high-performance curved face type battery efficientlyThe key that pole plate is manufactured.

Due to method of the present invention be the frame that does not need distortion is remained in the situation of compression grid rib orRib and frame do not have the even attenuation bending of shrinking, and the frictional force that compaction frame produces is greater than attenuation bend tension all the timePower, so the stress influence that plane net grid are out of shape by bending in forming process can not change original size of grid, thereby protectsDemonstrate,proved the dimensional accuracy of Curved-surface grid, and needn't be out of shape by pre-compensation, its method is simple, easily realizes. Equipment of the present invention is realThe concrete facilities and equipments of one of existing the inventive method, in plane grid bending deformation process, do not carry out bending frame and exist all the timeUnder the elastic pressure effect of upper and lower elastic material plate, and this elastic pressure makes upper and lower elastic material plate and does not carry out bending limitThe frictional force producing between frame is greater than attenuation bend tension power all the time, thereby does not carry out bending grid frame in frictional forceAct on the movement that can not deform, flexural deformation part produces even attenuation bending, the therefore Curved-surface grid after flexural deformationOutside dimension consistent with the plane grid outside dimension before bending, thereby ensured the dimensional accuracy of Curved-surface grid, and needn't be in advanceCompensation distortion. And for only at the upper and lower elastic material plate along the binder surface that distributes on feed direction, due to the length of binder surfaceThe flexure plane that degree size is greater than upper and lower bending die is along the length dimension on feed direction, and upper and lower bending die is to banded continuous net gridWhile carrying out flexural deformation, under the pressure limit effect of upper and lower elastic material plate, adjoin the interference deformation at flexural deformation position notCan exert an influence to net grid outside dimension, again because the flexure plane of upper and lower bending die is being greater than along the length dimension on feed directionThe feeding step pitch of mould, therefore can proofread and correct the interference deformation of last time bending generation, thereby has ensured the chi of continuous net gridVery little accuracy. Device structure of the present invention is simple, easy to use, and cost is low. Multi-station progressive stamping mould uses same entiretyOn mould bases, correcting hole stamping-out module, plane net grid stamping-out module, embossing module, bending module, lug hole and rim charge stamping-out moduleRelatively independent etc. functional module, can be according to each functional module of the different demands change different structures of grid moulding, modularMould structure is convenient to maintenance, the maintenance of mould, saves die cost.
