Problems solved by technology

At present, when most manufacturers produce grids, they use the traditional production process: using lead-calcium or lead-antimony alloys, which are cast by gravity casting on a casting machine. The production has the following problems: (1) Low production efficiency; (2) ) There are many quality problems of the grid, such as: air holes, too thin ribs, broken ribs, burrs, etc.; It also makes the grid easy to corrode, reduces the hydrogen evolution potential, causes more water loss, and shortens the service life of the battery

Abstract

The invention discloses a technology for forming maintenance-free lead-acid battery pole plates, comprising the following steps: (1) heating to melt an alloy lead liquid in a melting furnace; (2) casting the alloy lead liquid into lead strips by using a casting machine; (3) winding the lead strips by using a winder; (4) delivering the lead strips to a stamping machine and stamping the lead strips into plate grid strips (1), wherein uniform rectangular holes (2) are formed in the middle of each plate grid strip (1), ribs (3) are arranged among the holes (2), and edge and corner lead strips (4) used for cutting plugs are arranged on two sides of each plate grid strip; (5) winding the plate grid strips by using the winder; and (6) coating the plate grid strips by using a plate coating machine and splitting the plate grid strips by using a plate splitting mold to form lead-acid battery pole plates. The technology for forming maintenance-free lead-acid battery pole plates during lead-acid battery production can improve the service life, the quality and the specific energy of a lead-acid battery.

Description

technical field [0001] The invention relates to a technology for forming accessories of a maintenance-free lead-acid battery, in particular to a technology for forming a pole plate of a maintenance-free lead-acid battery. Background technique [0002] Lead-acid batteries are widely used because of their low price, reliable quality, large capacity range, easy maintenance, and long service life. With the use of regions and environmental conditions, the requirements for battery quality are getting higher and higher. To ensure the quality of the battery, there must be a high-quality plate, and the grid is an important part of the plate. At present, when most manufacturers produce grids, they use the traditional production process: using lead-calcium or lead-antimony alloys, which are cast by gravity casting on a casting machine. The production has the following problems: (1) Low production efficiency; (2) ) There are many quality problems of the grid, such as: air holes, too th...
