The second positioning component 3 includes two vertical blocks 13, and the two vertical blocks 13 are located on both sides of the loading plate 1, and the front end of the vertical block 13 is penetrated by a through plate 14, and a screw 15 is threaded through the upper end of the through plate 14 near one end, and a pressure plate 16 is fixedly installed on the lower end of the screw 15, and a sealing ring 17 is fixedly installed on the lower end of the pressure plate 16 near the periphery.

[0021] First, place the sheet metal to be processed on the loading plate 1. If the sheet metal needs to be cut, one end of the sheet metal to be cut is located on the outside of the loading plate 1 through the first positioning component 2 and the first positioning component 2. Start the electric telescopic column 9 to press the pressing plate 12 on the upper surface of the sheet metal and on the edge of the cutting side. Then rotate the screw 15 to make the pressure plate 16 contact with the sheet metal and press the sheet metal again to prevent the sheet metal from shifting at the moment of cutting, making the cutting more accurate.

[0022] Preferably, a spring 11 is sleeved on the outside of the guide column 10 , the lower end of the spring 11 is fixedly connected to the upper end of the pressure plate 12 , and the upper end of the spring 11 is fixedly connected to the lower end of the electric telescopic column 9 .

[0023] Preferably, the front and rear ends of the loading plate 1 are fixedly installed with electric slide rails 4, and the upper end of the electric slide rail 4 is movably connected with an electric telescopic plate 5, a horizontal plate 18 is fixedly installed between the two electric telescopic plates 5, and a metal inclined plate 19 is fixedly installed at the lower end of the horizontal plate 18, and the lower end of the vertical block 13 is fixedly connected to the upper end of the electric slide rail 4.

[0024] When the sheet metal needs to be laser cut, the second positioning component 3, the metal inclined plate 19 and the L-shaped plate 20 are set, and the pressure plate 16 of the second positioning component 3 presses one side edge of the sheet metal, and the electric slide rail 4 drives the electric telescopic plate 5 to move, so that the metal inclined plate 19 slides on the sheet metal. After the sheet metal remains horizontal, the screw 15 connected to the L-shaped plate 20 is rotated to press the pressure plate 16 on the other side edge of the sheet metal, so that the sheet metal is flattened and laser cutting is performed.
