Abstract

The invention relates to the technical field of lead-acid storage battery manufacturing, and discloses casting paint for the surface of a lead-acid storage battery cast welding machine. A component framework of conventional high-temperature alloy is broken through, the thermodynamic stability of a generated phase is good, the problems of wetting, interface reaction and the like between a welding phase and a welding surface do not exist, and various properties such as the melting point, the melting temperature range (intensity, toughness and creep resistance), physical and chemical properties (conductivity, oxidation resistance and corrosion resistance) and the like are remarkably improved compared with those of an existing welding method. The anti-fatigue performance is excellent, cleaningis not needed after welding, cleaning with freon is avoided, cleaning equipment and solvents can be saved, the environmental pollution is reduced, and the cost is appropriate.

Description

technical field [0001] The invention belongs to the technical field of lead-acid battery manufacturing, and in particular relates to a casting paint used on the surface of a lead-acid battery casting welding machine. Background technique [0002] Casting and welding machine, also known as fully automatic battery casting and welding machine. It is a small valve-controlled sealed lead-acid battery casting and welding equipment. The whole set of equipment includes fixtures, molds, furnaces, cooling devices, and demoulding and pool shell devices. The fixture is composed of two parts: a fixed plate and a slidable pressure plate on the base plate. The fixed plate is provided with positioning pins; the surface of the cast-welding mold is provided with busbars and pole-shaped grooves, and is provided with positioning holes for demoulding. The tank shell device includes a pneumatic demoulding device and a pneumatic tank shell device. The casting and welding equipment of the inventi...
