Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and specifically discloses a welding device for cold sheet metal processing. Background Technology

[0002] The comprehensive process of processing metal sheets, profiles, and pipes into various metal structural products without significantly altering their cross-sectional characteristics is called cold working, and workers engaged in cold working are called cold working workers.

[0003] Chinese patent CN216882438U discloses a welding device for cold-working sheet metal processing to reduce welding deformation. It includes a welding table and a welding machine mounted on top of the welding table. Fixed seats are provided on both sides of the top wall of the welding table. An installation groove A is formed in the plate of the fixed seat. A threaded rod A is disposed in the cavity of the installation groove A. A sliding sleeve B is screwed onto the rod body of the threaded rod A. Bent rods are hinged between the two side walls of the sliding sleeve B and the two side walls of the cavity of the installation groove A, respectively. A clamping plate is provided on the end of the bent rod near the welding machine. By rotating the threaded rod A, the sliding sleeve B moves on the threaded rod A. Under the action of the bent rod, the two sets of clamping plates move closer together, thereby effectively clamping and fixing the sheet metal, thus reducing welding deformation during the welding process and improving welding quality.

The welding device for cold sheet metal processing disclosed in the above document to reduce welding deformation can only connect two sheet metal pieces in parallel, which is not very practical.

When adjusting the left and right position of the welding machine 17, the third servo motor 20 is started. The third servo motor 20 drives the second lead screw 11 to rotate, which in turn drives the second U-shaped frame 13 to move left and right, thereby driving the welding machine 17 to move left and right. When adjusting the front and back position of the welding machine 17, the fourth servo motor 21 is started. The fourth servo motor 21 drives the third lead screw 14 to rotate, which in turn drives the slider 15 to move back and forth, thereby driving the welding machine 17 to move back and forth. Then, the second electric push rod 16 is started, which drives the welding machine 17 to move up and down, contacting the sheet metal for welding. By adjusting the angle and height of the sheet metal, the two sheet metal pieces can be connected at any angle, making it highly practical.
