Quick repair welding machine for anode steel claw

Abstract

The invention discloses a quick repair welding machine for an anode steel claw. The quick repair welding machine comprises a welding machine main rack, a welding machine pedestal, a transformer, a hydraulic station, a steel stick clamping device, a sliding limiting plate, a sliding limiting rod, a main hydraulic cylinder, a fixed clamping device, a sliding clamping device, a sliding clamping device hydraulic cylinder, a steel stick clamping device hydraulic cylinder, copper conductors, a high-pressure oil pipe, a welding control device and electrode contact blocks, wherein the steel stick clamping device clamps a steel stick; the fixed clamping device and the sliding clamping device clamp the anode steel claw to be repaired; and after the quick repair welding machine is electrified, the main hydraulic cylinder carries out contact welding on the steel stick and the anode steel claw to be repaired. Compared with the prior art, the quick repair welding machine for the anode steel claw hasthe advantages of high welding speed, long service life of the repaired steel claw, high conductivity, low material consumption and low manual consumption; the working efficiency is improved, and theuse effect is good; and the quick repair welding machine has popularization and use value.

Description

technical field [0001] The invention relates to welding equipment, in particular to a fast repair welding machine for anode steel claws. Background technique [0002] The anode steel claw is a consumable in the electrolytic aluminum industry, and its function is to control the anode carbon block and transmit current. Since the working environment temperature of the anode steel claw is above 1000°C, and the electrolyte in the electrolytic cell contains a relatively high NaF liquid, HF gas is released during the electrolysis process, and the anode steel claw is oxidized at high temperature and corroded by HF gas, the bottom of the anode steel claw is about 100mm The parts get thinner and shorter until the steel claws can't be used. Since the defective part of the anode steel claw only accounts for about 15% of the entire steel claw, and the rest are intact, in order to pursue economic benefits, various enterprises repair the damaged part of the steel claw before using it to p...

AI Technical Summary

Problems solved by technology

The steel claw repaired by this method has a short service life, a large amount of repeated repairs, a large amount of material consumption, a large consumption of artificial machinery, and a large amount of steel claw operation, which has become a troublesome headache for electrolytic aluminum enterprises, and has not been obtained for many years. Very good solution, which seriously restricts the technological innovation and development of enterprises
