[0021] Furthermore, the outer walls of the two support rods 503 are movably connected with a group of connecting rods 507, and one end of the two groups of connecting rods 507 is movably connected with a moving block 508. The opposite sides of the two moving blocks 508 are fixedly connected with compression springs 510, so that under the movably connected action of the connecting rods 507, the two moving blocks 508 can move relative to each other to compress the compression springs 510.

[0022] Furthermore, the tops of the two moving blocks 508 are fixedly connected with rings 509, the middle parts of the two rings 509 are movably connected with sliding rods 511, and the two ends of the sliding rods 511 are fixedly connected with U-shaped frames 512, so that the two rings 509 can slide on the sliding rods 511 driven by the moving blocks 508.

[0023] Furthermore, both sides of the bottom end of the U-shaped frame 512 are fixedly connected to the top end of the buffer plate 506. The bottom end of the buffer plate 506 in the initial position is five centimeters lower than the bottom end of the bending forming mold 9. When the bending cylinder 8 is opened to drive the bending forming mold 9 to move downward, the buffer assembly 5 can reduce the rigid impact of the bending forming mold 9 on the sheet metal body 2, thereby playing a certain buffering and protective role.

[0024] Furthermore, a sheet metal body 2 is movably arranged in the middle of the workbench 1, a bending groove 11 is opened in the middle of the top of the workbench 1, and clamping components 10 are provided on both sides of the inner wall of the bending groove 11. The clamping component 10 includes an electric telescopic rod 1001, one end of the electric telescopic rod 1001 is fixedly connected to one side of the inner wall of the bending groove 11, and the other end of the electric telescopic rod 1001 is fixedly connected to a clamping plate 1002, so that the clamping plate 1002 can be driven to move relative to each other when the electric telescopic rod 1001 is opened, so as to clamp and fix the sheet metal body 2.

[0025] Furthermore, a return spring 1003 is movably sleeved on the outer wall of the telescopic end of the electric telescopic rod 1001, and an anti-skid pad 1004 is fixedly connected to one side of the clamping plate 1002.

[0026] The working principle of the utility model is as follows: under the supporting action of the support column 4 and the top plate 7, the bending cylinder 8 drives the bending forming die 9 at the bottom end of the support plate 6 to move downward. When the sheet metal body 2 in the bending groove 11 is bent, the connecting plates 501 on both sides of the bottom end of the support plate 6 move downward. When the buffer plate 506 contacts the sheet metal body 2, it is squeezed and drives the U-shaped frame 512 to move upward. Then, under the rotation connection action of the two sets of connecting rods 507, the two moving blocks 508 move relatively to compress the compression spring 510, driving the two rings 509 to slide on the sliding rod 511. At this time, the two ends of the buffer plate 506 compress the buffer spring 504. Under the supporting action of the support rod 503 and the damping action of the damping 505, when the bending forming die 9 bends the sheet metal body 2, the rigid impact of the bending forming die 9 on the sheet metal body 2 can be reduced, which plays a certain buffering and protective role. At the same time, it can also reduce the strain rate of the sheet metal body 2 during bending and deformation, which is helpful to improve the quality of the forming surface of the sheet metal body 2. When the sheet metal body 2 needs to be bent, the two electric telescopic rods 1001 are turned on to drive the two clamping plates 1002 to move relative to each other. Under the elastic protection of the two return springs 1003 and the anti-slip effect of the two anti-slip pads 1004, the sheet metal body 2 is fixed more securely, which improves the positioning reliability and forming accuracy of the sheet metal body 2 when bending, and helps to enhance the stability of the sheet metal body 2 when bending and forming.
