Technical field
The utility model belongs to battery technology field.Be specifically related to one and effectively can realize the coated grid of lead plaster, improve the lead acid accumulator plate grid of lead plaster and grid adhesion.
Background technology
Traditional lead acid batteries grid adopts gravity casting mode to produce, technology maturation, but the shortcoming having that weight is large, production efficiency is low, not corrosion-resistant, process quality control deviation is large.There is the stretch grid afterwards, lightweight, production efficiency is high, corrosion resistance is strong, but because there is no left and right side frame, there is grid short circuit of should growing up and cause battery to shift to an earlier date the shortcoming of end-of-life.Adopt the punching grid that the cold rolling mode of machine is produced, have that corrosion-resistant, lightweight, life-span is long, production process is simple, the feature of steady quality, convenient management, grid can do thinner, thickness evenly, meet current lead acid accumulator to high power, energy-conserving and environment-protective technique direction development trend.
But punching grid alloy is fine and close, smooth surface, and the poor adhesive force of lead plaster, especially grid rib is at a right angle, and lead plaster easily comes off, and affects battery performance.
The forming method of general punching grid is as follows:
1. 6. grid is shaping to prepare the punching of lead alloy → 2. smelting lead alloy → 3. cast stereotype → 4. suppress. g., lead tape → 5..
First the lead alloy refined in advance is put into market pot, be warmed to 350 ~ 500 DEG C, by can the plumbous infusion of accurate flow control enter in the continuous stereotype model of band extruder, cast the stereotype of one fixed width and thickness, this stereotype forms the. g., lead tape of desired thickness after multi-roll mill rolls repeatedly, and. g., lead tape, after timeliness after a while, carries out continuous punching through porous punch press, form continuous print grid skeleton structure, fill (coated plate) for follow-up grid.
The grid adopting above method to produce can realize arbitrary shape design, and thickness general control is between 0.5mm ~ 2mm.
Fig. 1 to Fig. 4 is several typical grid shape.No matter adopt the grid of which kind of shape, grid rib is all square or rectangular cross-sectional, during coated plate, lead plaster can only be filled in the hole of grid or cover on coated plate face, whole coated to grid of lead plaster can not be realized, namely can not realize two-sided painting effect, the adhesion between lead plaster and grid is poor, causes lead plaster in storage battery production to come off.Lead plaster one side fills and can cause plate buckling in battery use procedure simultaneously, as shown in Figure 5, Figure 6.Fig. 5 is that lead plaster exists in grid hole, poor adhesive force, and lead plaster comes off to 2 directions, Fig. 6 one side coated plate, and lead plaster comes off to 1 direction.
Summary of the invention
The purpose of this utility model provides a kind of lead acid accumulator plate grid for above-mentioned deficiency exactly, improves the adhesion of punching grid and lead plaster.
Technical solution of the present utility model is: a kind of lead acid accumulator plate grid, comprises the punching lead acid accumulator plate grid be made up of frame, rib and mesh, it is characterized in that: described rib and scuncheon edge are the chamfering of 10 ~ 45 °; Described punching lead acid accumulator plate grid thickness is less than or equal to 1mm.
The utility model rib chamfered is that the right angle of grid rib in punching lead acid accumulator plate grid skeleton structure is carried out chamfered.Rib chamfered is employing roll-in method, pressing carries out the process of rib corner chamfering.
Adopt roll-in method to carry out the process of rib corner chamfering to comprise: after porous punch press, set up a circular pair roller, circular pair roller is made up of high-strength stainless steel material, the projection identical with grid structure and pore shape is made on the surface of pair roller, by the spacing of precision adjustment pair roller, projection during roll extrusion on pair roller is goed deep into grid hole and is extruded rib corner, rib four corner is squeezed into the rib chamfer shape of 10 ~ 45 °.
Adopt pressing to carry out the process of rib corner chamfering to comprise: after porous punch press, set up pair of planar stamping die, stamping die is made up of high-strength stainless steel material, flat die mould is made up of a series of drifts corresponding with grid rib pore structure, upper and lower punch die moves simultaneously, rib four corner is washed into the rib chamfer shape of 10 ~ 45 °.
The utility model is due on the basis of existing punching grid forming method, after the grid skeleton structure step will formed after porous punch press carries out continuous punching, turn increase rib chamfered step, chamfered is carried out by four corners, right angle of grid rib in continuous print grid skeleton structure, thus when lead plaster is filled from the grid one side after chamfered, lead plaster after being squeezed can be coated to the another side in grid, such lead plaster has coating and becomes " dumbbell " shape on the two sides of grid, pole plate is after overcuring drying process, lead plaster can firmly be attached on grid, lead plaster obscission can not be there is, improve pole group encapsulating and cast welding quality, ensure battery performance.The utility model has and realizes lead plaster in grid coated on both sides, the adhesion increasing lead plaster and grid, the feature that prevents cream situation from occurring.The utility model is particularly useful for the punching grid manufacturing high power storage battery.
