Abstract

An electrode plate grid of a lead-acid battery is disclosed in an embodiment in the invention and includes a frame disposed on a periphery of the electrode plate grid and a grid-shaped rib arranged inside the frame. The grid-shaped rib is twisted by 45 degrees through a mould in a stamping manner so that a cross section of the grid-shaped rib is in the shape of a rhombus. A twisting angle is an included angle between a twisted side and a horizontal surface. The rib, when being twisted, is subjected to a pattern-pressing process through a mould on a surface of the rib for increasing surface roughness of the rib. The invention also provides a producing mould and a preparation method of the electrode plate grid. The mould includes an upper part and a lower part. The upper part includes a punch fixing apparatus, a material discharging apparatus and a punch, wherein the material discharging apparatus and the punch are successively arranged under the punch fixing apparatus. The lower part includes a combined mould bracket and a combined concave mould which is disposed on the combined mould bracket. The punch on the upper part is arranged correspondingly to the combined concave mould of the lower part for stamping the electrode plate grid. The invention aims to provide the energy-saving and environmental-protective electrode plate grid and the producing mould thereof. In the electrode plate grid, a combination force between an active substance paste body and the plate grid is better.

Description

The preparation method of a kind of lead acid batteries electrode plate grid, production mould and electrode plate grid
Technical field
The present invention relates to lead acid accumulator field, particularly relate to the preparation method of lead acid batteries electrode plate grid, production mould and electrode plate grid.
Background technology
At present, the energy force rate of electrode punching grid anti-electrolyte acid corrosion in battery of lead acid accumulator adopts the casting type grid of the casting process manufacture of traditional handicraft to improve a lot, but due to punching grid smooth surface, the rectangular arrangement of all ribs of grid, just cause the active material lotion of battery after the drying of painting cream, along with the volatilization of moisture, the rib of active material volume contraction and grid occurs that adhesion does not even depart from by force, thus active material easily comes off, further cause lead acid accumulator shortening in useful life.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, provides a kind of energy-saving and environmental protection, active material lotion and the better lead acid batteries electrode plate grid of grid adhesion.
Described lead acid batteries electrode plate grid, comprise the frame being arranged at electrode plate grid periphery and the rib being arranged at the lattice-shaped in described frame, described rib uses the 45 ° of torsions of mould punching form, make described electrode plate grid section of ribs become rhombus, described torsion angle is the angle reversing limit and horizontal plane.
Described rib uses die surface embossing while torsion, increases rib surface roughness.
This structure is except frame, used by all rectangle ribs by electrode plate grid mould punching form to allow it reverse 45 °, electrode plate grid section of ribs is made to become rhombus by rectangle, and while reversing rib, make the. g., lead tape embossed surface of contact drift and combined die, increase rib surface roughness, make the area when slab lattice thickness direction center line of the mesh in grid plane minimum, center line both sides area is that radioactivity increases gradually, is more conducive to the adhesion of grid and active material.Cell active materials coating, dry when shrinking, because grid mesh thickness direction centerline sectional area is minimum, appearance sectional area is large, and two towards ensureing combining closely of active material and grid during middle shrinkage all the time, thus raising service lifetime of accumulator.
The embodiment of the present invention additionally provides the lead acid batteries electrode plate grid production mould that a kind of structure is simple, production efficiency is high.
The production mould of described lead acid batteries electrode plate grid, comprise upper and lower two parts, described upper part comprises drift fixture and is set in turn in device for discharging, the drift below drift fixture, described lower part comprises combined formwork and is arranged at the combined die on described group frame, the drift of described upper part is corresponding with the combined die of lower part to be arranged, for punching press electrode plate grid.
The embodiment of the present invention additionally provides a kind of preparation method of lead acid batteries electrode plate grid, comprises the steps:
(1), first the lead acid batteries electrode plate grid with rectangle rib is put on the combined die of lower mould;
(2), by upper mould to pressing down, rectangle rib is under the extruding of patrix drift and combined die, and shape torsion at 45 °, makes described electrode plate grid section of ribs become rhombus;
(3), reverse the. g., lead tape embossed surface making contact drift and combined die while rib, increase rib surface roughness;
(4), die sinking, make finished product.
The practical example of the present invention mould be punching die structure, include red needle fixture, device for discharging, drift, combined die and mould bases composition, be divided into punching station and rib to reverse station by technological requirement, punching station about mould, but must be at. g., lead tape Way in.According to production grid size or model specification different, can single step punching and multistep punching, but during minimum shaping punching, mould open/close number of times is less than or equal to 2 times.The red needle of punching station can be various shape, as shapes such as square, rectangle, trapezoidal, hexagons, but considers that to save the plumbous amount of consumption different with the distribution of current density during battery lead plate impulse electricity, and first-selected mesh form is rectangle and trapezoidal.It is upper and lower punch structure that rib reverses station, and upper lower punch Heterogeneous Permutation, counterdie is cover half, along with the stripper plate gate rib that presses down gradually of patrix makes it overturn.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail.
Lead acid batteries electrode plate grid described in the embodiment of the present invention, comprise the frame 1 being arranged at electrode plate grid periphery and the rib 2 being arranged at the lattice-shaped in frame, this structure is except frame 1, used by all rectangle ribs 2 by electrode plate grid mould punching form to allow it reverse 45 °, electrode plate grid section of ribs is made to become rhombus by rectangle, and while reversing rib, make the. g., lead tape embossed surface of contact drift and combined die, increase rib surface roughness, make the area when slab lattice thickness direction center line of the mesh in grid plane minimum, center line both sides area is that radioactivity increases gradually, more be conducive to the adhesion of grid and active material.Cell active materials coating, dry when shrinking, because grid mesh thickness direction centerline sectional area is minimum, appearance sectional area is large, and two towards ensureing combining closely of active material and grid during middle shrinkage all the time, thus raising service lifetime of accumulator.
