Full automatic hydraulic flash butt welding method of metal circular ring chain and apparatus thereof

Abstract

The invention relates the metallic bond full-automatic all-hydraulic flash butt welding method and device. The method is that the open of each chain link is automatically welded after the metallic bond is knitted to chain. The method comprises the following step: sending the chain link from left end of machine to position of welding under the combined action of main conveyer and subsidiary conveyer, controlling the hydraulic heading equipment with displacement transducer, servo valve and heading valve, preheating, burning, flashing and heading welding, auto removing the burrs, and exporting the finished chain link from the right end of machine. The whole process is the full-automatic all-hydraulic flash butt welding method. The invention possesses the characters of high automation level, high production efficiency, high product quality and high safe reliability. The said method and device will replace the national current fall behind electric milling cam type FBW method and device.

Description

technical field [0001] The invention relates to metal circular chain welding technology, in particular to a method and device for fully automatic full-hydraulic flash butt welding of metal circular chains. Background technique [0002] At present, the common metal circular chain flash butt welding equipment in China is the electric cam type. During the production, the motor is used to drive the cam to rotate a circle, and the movable clamp of the circular chain welding fixture in contact with it is pushed to complete the pre-set according to the curve of the cam. Heat, burn, flash and upset, so as to achieve the welding purpose of flash butt welding. The disadvantages of this type of equipment are: 1. The cam manufacturing requirements are high, the wear is serious during work, the process is unstable after wear, and the welding quality cannot be guaranteed. 2. After the cam profile is manufactured, it cannot be changed, so it cannot adapt to the welding of chain links in d...

AI Technical Summary

Problems solved by technology

The disadvantages of this type of equipment are: 1. The manufacturing requirements of the cam are high, the wear is serious during work, the process is unstable after wear, and the welding quality cannot be guaranteed

2. The shape of the cam cannot be changed after it is manufactured, so it cannot adapt to the welding of chain links in different conditions

3. Due to the large upsetting force and high upsetting speed, the power of the required motor is relatively large, and the utilization rate is very low

4. After welding, the welding flash and burrs cannot be removed at the same station

5. Manual loading and unloading and conversion, high labor intensity and low productivity, cannot realize fully automatic continuous welding
