Steel components are often cut using plasma cutting devices during use.

[0003] After searching, it is found that a plasma cutting device for steel components is disclosed in Chinese patent documents [Application No.: 202121405608.4; Publication No.: CN 215034392 U]. This plasma cutting device for steel components relates to the technical field of steel components, including a base, two support plates are welded on the top of the base, two slide grooves are provided on the top of the base, and the inner walls of the two slide grooves are slidably connected with a slide plate. In the utility model, during use, after the pallet is moved out, the steel component is placed on the pallet, and then the pallet is pushed into the top of the base so that the steel component contacts the second baffle, and the first baffle is fixed to the steel component by the electric telescopic rod, thereby preventing the steel component from moving, and the first rod can prevent the first baffle from being offset when the first rod limits the first baffle, thereby preventing the first baffle from bending and causing damage, and the pallet can be moved by the slide plate and the slide groove, and the lifting arm is driven to move by the slide tube, and the lifting arm drives the sliding block to move, and the sliding block moves to drive the cutting body to move, so that the cutting body can better cut the steel component.
