Technical Field

The invention relates to the technical field of storage battery processing equipment, in particular to a grid continuous casting and coating production line.

Background

The grid is a main component of a lead-acid storage battery and has three grid production modes of casting, net drawing and net punching. The traditional grid casting process mainly adopts a gravity casting mode, and the main equipment is a plate casting machine and a corresponding matched grid mould. The casting is to pour the lead alloy after being heated and melted into a plate grid mould under the action of gravity, then to cool and form, and then to process the lead alloy after subsequent processing. The plate casting machine needs an experienced operator to operate, the surface of a casting mould is treated according to the casting result of the grid, and a certain thickness of 'release agent' is sprayed to obtain a qualified product. The grid formed by gravity casting has the advantages that the thickness of the grid cannot be too thin, the thickness can only reach more than 1.0mm generally, the thin grid cannot be produced, certain limitations exist in the structural design of the grid, the utilization rate of raw materials is low, the proportion of active substances to the grid is general, the automation level is low, the labor intensity is high, the production efficiency is low, the production cost is high, the pollution degree in the production process is high, the energy consumption of equipment is high, the material consumption is high, the body of an operator is injured, the quality also depends on the technology of the operator, the quality cannot be stable, the self-discharge rate and the water loss rate are high, the service life is short, and the corrosion resistance is poor.

Further, the oil quantity is too large, and a grid is not shaped; the adhesion of oil mass undersize grid rib and casting die cavity, serious probably compelled to overhaul, influence production efficiency. (2) Because certain contact pressure exists between the rotary die and the fixed die at certain casting temperature, the thermal deformation and abrasion of the rotary die and the fixed die are aggravated, the service life of the die is seriously influenced, and the quality problem of a cast grid is caused. (3) In the casting process, molten lead alloy is led in from one end of the fixed die through the lead conveying pipeline, and led out from the other end of the fixed die, so that the attenuation of temperature and lead supply pressure can inevitably cause influence on the demoulding and deformation of a cast grid under severe conditions, and therefore, the invention provides a grid continuous casting and coating production line to solve the problems in the prior art.
