200 liter steel drum continuous open automatic seam welding machine
Shanghai Petroleum Purchasing Supply Station Co., Ltd.
200-liter steel drum continuous open automatic seam welding machine, using the principle of resistance heating, using low voltage, high current output, welding transformer and upper and lower electrodes to form a welding circuit, heating the weld to a plastic molten state, and then with pressure Continuous seam welding is achieved by the mechanism and the automatic adjustment of the drive transmission.
The successful development of the 200-liter steel drum continuous open automatic seam welding machine provides relatively advanced technical equipment for the steel barrel seam welding process. The replacement of manual welding barrels by the side-opening automatic seam welding machine has a significant effect on improving labor productivity, reducing labor intensity, reducing noise, improving working conditions, saving energy and improving seam quality of steel barrels.
The main technical parameters of the 200-liter steel drum continuous open automatic seam welding machine:
1. Transformer power: 250KVA, secondary water-cooled;
2. Welding load meter renewal rate: 95%;
3. Thickness of welded steel plate: 1.25+1.25 mm;
4, welding current: primary 400 amps, secondary 30000 amp;
5, welding speed: 2.5 ~ 5.5 m / min;
6, the effective length of the electrode arm: 1.015 meters;
7, the maximum working pressure of the welding wheel: 550 kg;
8, the working pressure of the transmission mechanism: 250 kg;
Working quality indicators of 200-liter steel drum continuous open automatic seam welding machine:
1, welding overlap: 4 ~ 4.5 mm;
2, destructive test: meet the standard requirements of GB325;
3. The qualified rate of finished products of welds: 97% or more;
4, the appearance of the weld: neat and beautiful.
The 200-liter steel drum continuous open automatic seam welding machine has reasonable layout, compact structure, good performance and convenient operation, and provides the prototype of the steel barrel automatic seam welding machine.
Used in actual production, it can change the current manual seam welding process. The two processes of grinding and spot welding are eliminated, and continuous automatic seam welding is realized to achieve high-quality, high-quality and low-consumption steel drums, saving labor, reducing labor intensity, reducing noise and improving working conditions.
However, improvements are needed in the following areas:
1. Strengthen the structural rigidity of the whole machine, further improve the rounding and conveying pneumatic devices;
2. Improve the quality of the welding wheel and improve the hardness, electrical conductivity and oxidation resistance;
3. Improve the cooling system of the welder.
