The double-headed liner welding machine is another pioneering work of all welding machines. The joint operation of seam welding and spot welding is suitable for welding boxes, liners, etc., suitable for stainless steel and other materials. This time, we will take the welding liner as an example. Show it to our customers and friends.
Description of the basic structure of the welding equipment of the resistance longitudinal seam welding machine
Frame | It adopts a vertical structure, welded with high-quality steel, and is annealed and aging treated after welding to ensure that the machine has sufficient strength, rigidity and stability. |
Pressure mechanism | The pneumatic vertical pressurizing device is used to distribute the arms on the frame to ensure the welding pressure and the welding workpiece is smooth and correct, and is equipped with a pneumatic triplet, which can effectively filter the water in the air and lubricate the cylinder of the pressurized part; The cylinder guide shaft is made of high-quality alloy steel after high-frequency treatment and chrome-plated. The guide sleeve is used for guiding when the guide shaft runs up and down to ensure that there is no creeping phenomenon when the cylinder is running, so as to ensure the reliability of welding pressure and welding quality. |
Conveying mechanism | The cylinder is used to push the fixture from the position where the workpiece is placed to the working position for welding, and the welding wheel presses the workpiece, and the welding is completed and automatically returns to the clamping position. |
Conductive parts | The movable conductor adopts red copper foil to conduct electricity, which has a good heat dissipation effect and a long service life, which reduces the use cost. The conductive plate is made of high-quality copper material with good conductivity. The seam welding head uses silver tiles to automatically compensate for the wear gap. The conductive surface is immersed in the conductive liquid to facilitate conduction. The electric shaft is supported by a tapered roller bearing with a large load capacity. The seam welding head The internal water-cooling pipeline is designed to greatly improve the heat dissipation conditions. The seam welding wheel is made of chromium zirconium copper, which has good electrical conductivity and high hardness. |
Welding electrode | The electrode is made of rare-earth alloy copper processing, which has sufficiently high electrical conductivity, thermal conductivity and high-temperature hardness; the structure of the electrical component pole has sufficient strength and rigidity |
