Problems solved by technology

The hole size of the lead-acid storage battery grid that adopts these methods to produce is big, is generally 6mm * 8mm; The area is small, so that the lead-acid battery plate produced by the prior art grid has low utilization rate of active materials, poor charge and discharge performance of the battery, low specific energy, and short service life, which can no longer meet the needs of the development of lead-acid batteries.

Embodiment 1

[0031] A method for producing a lead-acid battery expanded grid, comprising the following steps:

[0032] Rolling the pure lead metal strip to make the Vickers hardness value of the lead metal strip reach the set value;

[0033] After the rolling process, the lead metal strip enters the roll-cutting stretch-net forming machine through the feeding device to undergo plastic deformation, and rolls and cuts on the surface of the lead metal strip to form at least one mesh warp strip;

[0034] The lead metal strip after roll cutting stretches and expands the mesh holes on the surface of the lead metal strip through the mesh forming mechanism to form the lead metal mesh;

[0035] The formed lead metal mesh is sandblasted with 16 mesh brown corundum, the sandblasting pressure is 2kg, and the time is 22min, so that the surface is rough and the adhesion is increased;

[0036] The lead metal mesh is collected after being cut by a cutting device.

Embodiment 2

[0038] A method for producing a lead-acid battery expanded grid, comprising the following steps:

[0039] Roll the lead-tin alloy strip to make its Vickers hardness value reach the set value;

[0040] After rolling, the lead-tin alloy strip enters the roll-cutting stretch-net forming machine through the feeding device to undergo plastic deformation, and rolls and cuts on the surface of the lead-tin alloy strip to form at least one mesh warp belt;

[0041] The lead-tin alloy strip after roll-cutting stretches and expands the mesh on the surface of the lead metal strip through the stretching mesh forming mechanism, so that the lead-tin alloy mesh is formed;

[0042] Sandblasting the formed lead-tin alloy mesh with 24 mesh glass beads, the pressure of sandblasting is 3kg, and the time is 30min, so that the surface is rough and the adhesion is increased;

[0043] The lead-tin alloy mesh is collected after being cut by a cutting device.

Embodiment 3

[0045] A method for producing a lead-acid battery expanded grid, comprising the following steps:

[0046] Roll the lead-antimony alloy strip to make its Vickers hardness value reach the set value;

[0047] After the rolling process, the lead-antimony alloy strip enters the roll-cutting expanded mesh forming machine through the feeding device to undergo plastic deformation, and rolls and cuts on the surface of the lead-antimony alloy strip to form at least one mesh warp belt;

[0048] The rolled-cut lead-antimony alloy strip stretches and expands the mesh on the surface of the lead-antimony alloy strip through the stretching mechanism to form the lead-antimony alloy mesh;

[0049] Sandblasting the formed lead-antimony alloy mesh with 36-mesh brown corundum, the sandblasting pressure is 4kg, and the time is 35min, so that the surface is rough and the adhesion is increased;

[0050] The lead metal mesh is collected after being cut by a cutting device.

Abstract

The invention provides a production method of a lead-acid battery dragnet grid, comprising the following steps: rolling a raw material lead metal strip to make the Vickers hardness value of the lead metal strip reach a set value; The rolled lead metal belt enters a rolling mesh forming machine through a feeding device and undergoes plastic deformation, and at least one mesh hole is formed on the surface of the lead metal belt by rolling. The lead metal belt after rolling is stretched and expanded to the mesh holes on the surface of the lead metal belt through a drawing mesh forming mechanism,so that the lead metal mesh is formed; Sand blasting is carried out on the formed lead metal mesh to make its surface rough and increase the adhesion force; Cut the lead metal mesh through the cuttingdevice and collect it. The production method of the lead-acid battery dragnet grid provided by the invention effectively increases the adhesion area of the battery active material by sandblasting andstretching the grid, so that the active material adhered on the battery is not easy to fall off and the service life is longer.

Description

technical field [0001] The invention belongs to a production method of a grid, in particular to a production method of a lead-acid battery pull-net type grid. Background technique [0002] At present, the grids of lead-acid batteries in the prior art are basically produced by the gravity casting method, the lead strip continuous rolling expansion method and the lead strip punching method. The hole size of the lead-acid storage battery grid that adopts these methods to produce is big, is generally 6mm * 8mm; Due to the small area, the lead-acid battery plate produced by the prior art grid has low utilization rate of active materials, poor charge and discharge performance of the battery, low specific energy, and short service life, which can no longer meet the needs of the development of lead-acid batteries. Contents of the invention [0003] Technical problem: In order to solve the defects of the prior art, the present invention provides a production method of a lead-acid ...
