Description

A kind of accumulator grid continuous casting and rolling roll

Technical field

The utility model relates to a kind of roll structure, is specifically related to a kind of accumulator grid continuous casting and rolling roll.

Background technology

The main effect of the grid in the lead-acid accumulator is conduction and compiles electric current, and makes CURRENT DISTRIBUTION even, is to support active material on the other hand.Grid is conducting matrix grain, is again that active ingredient carriers has dual merit.Therefore, to grid certain machinery, electricity, metallurgical characteristics requirement to be arranged.Namely require grid to possess favorable mechanical performance (comprising hardness, tensile strength, casting character, solderability), excellent corrosion resisting performance and favorable conductive ability.

At present, the mode of making lead acid accumulator plate grid mainly contains and draws in the net, continuous casting roll-in tandem rolling, gravity casting and the expansion of forging band, cast type expansion and punching press and punching rolling etc., commonly used is the gravity casting technology, but the reason owing to aspects such as mould, pressure, there are shortcomings such as the surface is rough, loosely organized, corrosion-resistant difference in the grid of gravity casting fabrication techniques.The battery that adopts this class grid to make is short service life, and charge-discharge performance is poor, has problems such as lead-acid accumulator grid corrosion in use is fast, cycle life is short.

And the grid that adopts conticaster to utilize continuous casting roll-in continuous rolling technology to make, optimizing the grid design, performance and microstructure aspect are significantly improved, can design the grid of any thickness, can take full advantage of existing grid band and fill equipment, and can change grid material composition and microstructure, and provide prerequisite for promoting active material adhesive force, its inherent buttress shaft shape crystal grain microstructure and lamination layer structure have strengthened grid corrosion resistance and lead plaster tack, be conducive to improve grid corrosion resistance and lead plaster adhesive force, flexibility is better than all grid manufacturing process at present greatly, slab lattice thickness can reduce to current-carrying, corrosion and process needed minimum thickness, can reduce resistance loss, and have the favorable mechanical performance.With respect to present widely used gravity casting method, continuous casting and rolling method production efficiency height, production environment is good, and product cost is low, and grid intensity height is organized the tiny and difficult generation intercrystalline corrosion of crystal grain.Can produce the desired grid of dissimilar batteries.By reducing the corrosion resistance prolongation battery service life that weight improves power and the energy density of battery and passes through to improve grid.

At present, make the grid conticaster of stereotype, after plumbous liquid adds between two rolls, plumbous liquid forms stereotype by cooling and the roll compacting of roll, but because existing roller surface smoother all, form easily between stereotype and the roll and skid, cause the frictional traction on the stereotype two sides that is rolled inhomogeneous, make the rolling stereotype that comes out offset to one side or produce buckling phenomenon.Therefore can not normally be sent to down manufacturing procedure one, so be necessary existing stereotype roll structure is improved.

The utility model content

The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of accumulator grid continuous casting and rolling roll is provided.

For achieving the above object, the technical solution of the utility model is a kind of accumulator grid continuous casting and rolling roll of design, it is characterized in that described roll comprises a pair of knobbling rolls, be provided with groove and/or fin on the surface of described roll, or be provided with salient point and/or concave point on the surface of described roll.

Wherein optimized technical scheme is, described groove and/or fin are distributed on the surface an of roll or a pair roller.

Further optimized technical scheme is that the groove of described roller surface and/or fin are the corrugation toothing.

Further optimized technical scheme also has, and described corrugation tooth is straight-tooth or is helical tooth.

Further optimized technical scheme also has, and described helical tooth comprises left-hand screw and/or right-hand screw.

Further optimized technical scheme also has, and the groove of described roller surface and/or fin are reticulate structure.

Optimized technical scheme also has, and described salient point and/or concave point are distributed on the surface an of roll or a pair roller.

Further optimized technical scheme also has, at surperficial alternate groove and/or fin and salient point and/or the concave point of being provided with of described roll.

Further optimized technical scheme also has, and the radial dimension of described groove and/or fin and salient point and/or concave point is 0.3mm ~ 0.8mm, the spacing 〉=5mm of adjacent notches and/or fin and salient point and/or concave point.

Advantage of the present utility model and beneficial effect are: because this accumulator grid continuous casting and rolling roll, be provided with groove and/or fin and salient point and/or concave point on its surface, the groove of the stereotype surface that is rolled and roller surface and/or fin and salient point and/or concave point are cooperatively interacted together, thereby form feeding tractive force equably, make and steadily to be transmitted along rectilinear direction by the stereotype after the roll compacting.So both improve the quality that is rolled stereotype, also improved the rolling efficiency of stereotype simultaneously.This stereotype roll improves simple in structure, is easy to processing, and service life is longer.Be forced out the stereotype of groove and/or fin and salient point and/or concave point, also be conducive to adhere in its surface lead plaster.
