[0023] The technical solution of the present invention is described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1 to 9As shown, a sheet metal cutting and welding device described in this embodiment includes, from left to right, an unwinding mechanism 1 installed on a complete machine frame 100, a first calibration mechanism 2, a leveling mechanism 3, a first cutting mechanism 4, a second calibration mechanism 5, a clamping and conveying mechanism 6, a second cutting mechanism 7, a first clamping and rotating mechanism 8, a second clamping and rotating mechanism 9, a welding mechanism 10, a welding clamping mechanism 11 and a discharge conveyor belt 12, wherein the first calibration mechanism 2 has the same structure as the second calibration mechanism 5, the first calibration mechanism 2 includes a calibration seat 201 sliding back and forth on the complete machine frame 100, and two rows of calibration rollers 202 installed on the calibration seat 201, and a telescopic mechanism is installed on the complete machine frame 100 for driving the calibration seat 201 to move back and forth, so that the coil discharged from the unwinding mechanism 1 enters the leveling mechanism 3 in an aligned manner, and the telescopic mechanism here adopts a structure: including a reciprocating motor 203 installed on the complete machine frame 100, and the reciprocating motor 203 is connected to the calibration seat 201, thereby driving the calibration seat 201 to move back and forth. The leveling mechanism 3 is composed of multiple pressure rollers arranged up and down. The upper pressure roller is driven by the leveling motor 301 to press it down to flatten the coil, and a first feeding motor 302 is also connected to the side of one of the pressure rollers. The first feeding motor 302 drives the corresponding pressure roller to convey the sheet material. The first cutting mechanism 4 has the same structure as the second cutting mechanism 7. The first cutting mechanism 4 includes a first cutting frame 401 that slides left and right on the whole machine frame 100. The whole machine frame 100 is provided with a rack. A cutting left and right motor 402 is provided at the bottom of the first cutting frame 401. A gear that cooperates with the rack is connected to the end of the cutting left and right motor 402, thereby driving the first cutting frame 401 to move left and right. A cutting moving seat 403 is slidably provided on the top of the first cutting frame 401 along the width direction of the whole machine frame 100. The cutting moving seat 403 is driven to move forward and backward by a cutting front and rear motor 407. A cutting lifting plate 404 is slidably provided on the cutting moving seat 403 in the vertical direction. A cutting lifting motor 408 is provided on the cutting moving seat 403 to drive the cutting lifting plate 404 to rise and fall. The first laser cutting mechanism 405 is installed on the cutting lifting plate 404, and a bracket 406 for placing the sheet is provided below the first laser cutting mechanism 405. The first cutting mechanism 4 is used for opening holes, and the second cutting mechanism 7 is used for cutting the sheet. Therefore, the difference between the second cutting mechanism 7 and the first cutting mechanism 4 is that the second cutting frame 701 of the second cutting mechanism 7 is fixedly installed on the whole machine frame 100, and the other parts are the same as the first cutting mechanism 4. The clamping conveying mechanism 6 clamps the sheet and then conveys it. One of the pressure rollers is connected to the second feeding motor 601. When cutting, the second feeding motor 601 stops rotating, and the clamping conveying mechanism 6 presses the sheet to cut. When the sheet cutting is completed, the second feeding motor 601 works to feed the sheet.

[0025] Specifically, the first material clamping rotating mechanism 8 and the second material clamping rotating mechanism 9 have the same structure. The second material clamping rotating mechanism 9 includes a material clamping sliding seat 901 that is slidably connected along the length direction of the entire machine frame 100. The material clamping sliding seat 901 is rotatably connected to a rotating rod 902. The end of the rotating rod 902 is connected to a material clamping seat 903. The material clamping seat 903 is equipped with a first material clamping motor 904 and two movable material clamping blocks 905 driven by the first material clamping motor 904. Motor 904 is a linear motor, and its working end is hinged with two connecting rods, each connecting rod is hinged to a gear that is rotatably connected to the clamping sliding seat 901, and the two movable clamping blocks 905 are slidably connected to the clamping sliding seat 901 along the vertical direction. The sides of the movable clamping blocks 905 have racks that mesh with the gears. Therefore, when the first clamping motor 904 works, it drives the two gears to rotate through the two connecting rods, thereby driving the two movable clamping blocks 905 to move toward or away from each other, which is used to clamp or release the sheet material. The whole machine frame 100 is provided with a belt 906 driven by a motor, and the belt 906 is connected to the clamping sliding seat 901 for driving it to move. The clamping sliding seat 901 is installed with a rotating motor 907, and the working end of the rotating motor 907 is connected to the rotating rod 902 for driving the clamping seat 903 to rotate. Therefore, after the first clamping rotating mechanism 8 clamps the sheet material, it can move along the length direction of the whole machine frame 100 and can rotate an angle. The first clamping rotating mechanism 8 cooperates with the second clamping rotating mechanism 9 to clamp the two ends of the sheet material respectively, so that the sheet material can be bent and the two ends of the sheet material can be butted together to facilitate subsequent welding.

[0026] Specifically, the welding mechanism 10 includes a welding frame 101 and a welding head 102 slidably connected to the welding frame 101 along the vertical direction. A welding lifting motor 103 is installed on the welding frame 101. The welding lifting motor 103 is a linear motor. The welding lifting motor 103 is connected to the welding head 102 to drive the welding head 102 to rise and fall. The welding clamping mechanism 11 includes a welding clamping frame 111 which is slidably connected to the whole machine frame 100 along the width direction of the whole machine frame 100, a welding moving motor 112 is installed on the welding clamping frame 111, the whole machine frame 100 is provided with a rack, the end of the welding moving motor 112 is connected with a gear matching with the rack for driving the welding clamping frame 111 to move, two welding clamping blocks 113 are slidably connected to the welding clamping frame 111, the driving mode and connection structure of the two welding clamping blocks 113 are the same as the two moving clamping blocks 805, that is, the two welding clamping blocks 113 are slidably connected to the welding clamping frame 111 along the vertical direction, and a second clamping motor 115 is installed on the welding clamping frame 111, and the second clamping motor 115 drives the two gears to rotate through two connecting rods, thereby driving the two welding clamping blocks 113 to move. The upper welding clamp block 113 has a vertically penetrating notch 114 on its upper portion, into which the welding head 102 can be inserted to allow the welding head 102 to weld the sheet material between the two welding clamp blocks 113 .

[0027] Specifically, a material receiving hopper 13 is provided below the welding mechanism 10. The material receiving hopper 13 is below the welding head 102. The material receiving hopper 13 is connected to the discharge conveyor belt 12, so that the welded material can be smoothly delivered.

[0028] When the present invention is working, the coiled material unwound by the unwinding mechanism 1 first enters the first calibration mechanism 2, and then enters the leveling mechanism 3 for leveling. After the sheet material is leveled, the first cutting mechanism 4 cuts the sheet material, such as drilling a hole. The cut sheet material then enters the second calibration mechanism 5 for calibration. After calibration, the sheet material enters the clamping and conveying mechanism 6 for clamping. The clamping and conveying mechanism 6 conveys intermittently. When the clamping and conveying mechanism 6 stops feeding, the second cutting mechanism 7 cuts the sheet material. Before the sheet material is cut, the first clamping and rotating mechanism 8 and the second clamping and rotating mechanism 9 are both located at the far left. During the cutting process, the second clamping and rotating mechanism 9 located at the right end first clamps the right end of the sheet material (a small section of the sheet material still protrudes from the second clamping and rotating mechanism 9). After the sheet material is cut, the second clamping and rotating mechanism 9 moves right. Until the left end of the sheet is located at the first clamping rotating mechanism 8, the first clamping rotating mechanism 8 clamps the material (a small section of the sheet still protrudes from the first clamping rotating mechanism 8), the first clamping rotating mechanism 8 and the second clamping rotating mechanism 9 rotate simultaneously, so that the sheet is cylindrical, and the front and rear ends of the sheet are butted together. At this time, the welding clamping mechanism 11 is at a position away from the first clamping rotating mechanism 8. When the first clamping rotating mechanism 8 and the second clamping rotating mechanism 9 move to the position of the welding mechanism 10, the welding clamping frame 111 on the welding clamping mechanism 11 moves and makes the two welding clamping blocks 113 located at the butt joint at both ends of the sheet. The two welding clamping blocks 113 clamp the sheet, and the welding head 102 extends into the slot 114 and contacts the butt joint of the sheet for welding.
