Method and special device for performing fusion welding on electrode lead plate of energy-saving environment-friendly type lead-acid battery

Abstract

The invention provides a method and a special device for performing fusion welding on an electrode lead plate of an energy-saving environment-friendly type lead-acid battery, relating to the manufacturing technology of lead-acid batteries. The method provided by the invention comprises the following steps: (1) heating and melting solid lead for being infused into a lead storage tank or a lead injection tank to melt the lead, and preheating a melting template; (2) shifting the melting template to tightly cling to the lead storage tank, driving plunger rods to raise through the action of a cylinder on the lead storage tank or the lead injection tank, infusing liquid lead into a rectangular groove of the melting template, and closing taper holes through the plunger rods; (3) shifting the melting template to a station for fusion welding, pushing a tooling box to lead the lower surface of the tooling box to stick on the upper surface of the melting template, and inserting a small rectangular relief block in the liquid lead inside the rectangular groove of the melting template for 2-10seconds; (4) cooling the melting template; and (5) separating a box body of the tooling box from the melting template and then taking out a product. The device provided by the invention consists of a lead melting furnace, the lead storage tank or the lead injection tank; an electric heating induction coil is fixed on the lead melting furnace; the lead storage tank is provided with an electric heating pipe, the taper holes, a cylinder piston rod and a linkage plate; and a liquid inlet pipe arranged on the side wall of the upper part of the lead storage tank is communicated with a liquid outlet pipe of the lead melting furnace. The method and the special device provided by the invention have the advantage that: little liquid lead is used so as to meet the energy-saving requirement during the process of lead injection.

Description

Technical field: [0001] The invention relates to a lead-acid battery manufacturing technology, in particular to an energy-saving and environment-friendly lead-acid battery electrode lead plate welding method and a special device thereof. Background technique: [0002] The lead plate structure of the parallel electrodes of the lead-acid battery is that 8-15 lead plates are arranged in parallel in each cavity, and a small rectangular convex plate is extended from the top of each lead plate, and a number of cuboid longitudinal lead bars perpendicular to the lead plate will be arranged The small rectangular raised plates are welded to form a conductive connecting body. [0003] The existing technology is to attach fiber cloth to the planes on both sides of several lead plates and then insert them into parallel slots on the tooling box to implement the arrangement and positioning of parallel lead plates. The lead plates are divided into several groups, and several lead plates in ...

AI Technical Summary

Problems solved by technology

[0008] 1. The amount of lead injected at one time is only 120-140 grams, and one ton of liquid lead in the lead pool needs to be heated and kept warm, which is a huge waste of energy

[0009] 2. The high temperature of the investment mold assembly reaches more than 300 degrees, and it drops to about 200 degrees when cooling, while the inlet water temperature is 20-30 degrees. Cracks and leaks occur, whether water drips into the lead pool from above or overflows in the lead pool, it will cause the liquid lead in the lead pool to detonate

[0010] 3. The cabinet of the fusion welding device shall have a door panel, which is opened and closed 500 times per working day, so as to take the workpiece out of the inner tooling box. When opening the door panel, it is all manually operated, and the lead gas puff will cause physical hazards and pollute the environment in the face of the operation work.
