A stainless steel side seam welding equipment

Abstract

The utility model belongs to the field of welding technology, and is particularly a stainless steel side seam welding device. In view of the problem that the ends of the circular placement frames used for fixing in the existing equipment are sealed and have a fixed inner diameter, which makes it impossible to place materials horizontally and limits the diameter of the materials, thereby reducing the efficiency of installation and disassembly, the following scheme is proposed, which includes an operating table, and electric cylinders are fixedly installed on both sides of the bottom end of the operating table by bolts. The tops of the two electric cylinders are extended through the operating table by plug-in telescopic rods and are fixedly connected with clamping components. The utility model drives the clamping screws to rotate synchronously through two clamping motors to control the rollers on the two groups of clamping slide blocks to move closer or farther from each other, so as to clamp the two pipes to be welded, increase the diameter size range of the pipes that can be clamped by the clamping components, and because of the use of roller clamping, the two pipes can be rotated arbitrarily, so that the arc-shaped welding seam is evenly in contact with the welder, thereby improving the welding efficiency and uniformity.
