Abstract
The invention relates to a cast-weld method of a lead pole with a copper core. It comprises the following steps: (1) placing the mould into a lead pan, keeping a cavity of the mould above the level of lead liquid, and soaking a mould matrix below the cavity in the lead liquid to heat the mould matrix in the lead liquid to reach the temperature of a cast-weld process; (2) after the temperature of the welding process is reached, lifting the mould out of the lead pan, and placing the copper core at the position of the corresponding pole in the mould; (3) putting the whole mould into a lead pan, and keeping the cavity of the mould below the lead liquid level so that the lead liquid can rapidly enter the cavity of the mould; (4) after the cavity is filled with the lead liquid, immediately lifting the die out of the lead pan, and putting the cluster electrode lugs into the cavity of the die for cast welding; (5) and cooling and demoulding are carried out while the cast welding is carried out. The invention ensures the product quality of the electrode and improves the production efficiency.
Description
Technical Field
The invention relates to a manufacturing process of a lead-acid storage battery pole, in particular to a cast-weld method of a lead pole with a copper core.
Background
At present, the lead-acid storage battery is still an important direct-current power supply and is widely applied to various industries. The lead terminal is a main component of the lead-acid storage battery and is generally manufactured by welding through a mold. The manufacturing process is very complicated, the lead melting temperature is very high, and the labor intensity is very high. Currently, a relatively simple process in the battery industry is dip mode welding. Dip mode welding is generally used for post welding of small density batteries without a copper core. Because the medium and large density battery pole generally has a copper core, the copper core is easily oxidized and blackened by adopting a general immersion mode process, the appearance of the product is influenced, and the conductivity is also reduced, so that other complicated manufacturing methods can be adopted. Therefore, the cast-weld method of the lead pole with the copper core is very beneficial.
Disclosure of Invention
The invention aims to provide a cast-weld method of a lead pole with a copper core, aiming at the defects of the existing cast-weld method of the lead pole with the copper core of a lead-acid storage battery. The method solves the technical problem that the lead pole with the copper core cannot be welded in a dipping mode, and improves the labor efficiency of the processing quality of the lead pole with the copper core.
The technical scheme of the invention is realized as follows: it comprises the following steps:
(1) placing the mould into a lead pan, keeping a cavity of the mould above the level of lead liquid, and soaking a mould matrix below the cavity in the lead liquid to heat the mould matrix in the lead liquid to reach the temperature of a cast-weld process;
(2) after the temperature of the welding process is reached, lifting the mould out of the lead pan, and placing the copper core at the position of the corresponding pole in the mould;
(3) putting the whole mould into a lead pan, and keeping the cavity of the mould below the lead liquid level so that the lead liquid can rapidly enter the cavity of the mould;
(4) after the cavity is filled with the lead liquid, immediately lifting the die out of the lead pan, and putting the cluster electrode lugs into the cavity of the die for cast welding;
(5) and cooling and demoulding are carried out while the cast welding is carried out.
The temperature of the cast-weld process is 420 ℃. The temperature of the lead liquid in the lead pot is 500 ℃.
The invention adopts twice die dipping heating, and only heats the die without adding the copper core in the first die dipping heating. Therefore, the copper core can stay in the lead pot for a short time, only a few seconds are needed, the copper core cannot be oxidized and blackened, the product quality is ensured, and the production efficiency is improved.
