Through the arrangement of the bolt rod, the upper cross rail, the first spring, the guide rod, the lower cross rail, the support block and the sliding assembly, compared with the prior art, the lower cross rail and the upper cross rail are brought close to each other so that the corresponding sliding assemblies can be brought close to each other vertically, so that the two ends of the magnesium alloy plate can be clamped and fixed, thereby preventing the two ends of the magnesium alloy plate from tilting during bending, and fixing the bending point to prevent the magnesium alloy plate from sliding in one direction during bending, thereby ensuring that the magnesium alloy plate can be bent at the bending point, thereby improving the product quality after the magnesium alloy bending process;

[0023] 2. Through the slide.

[0032] In the specific implementation, the magnesium alloy sheet is placed on two supporting mechanisms 7, and the bending point of the magnesium alloy sheet is located just above the middle of the bending groove 9. The heating component inside the workbench 1 is operated to heat the magnesium alloy sheet placed on the top of the workbench 1. When bending, the hydraulic pump 3 is operated to make the hydraulic rod 10 press down the fixed plate 4, so that the fixed plate 4 is lowered, so that the two pressing mechanisms 6 are first pressed on the corresponding supporting mechanisms 7, so that the two ends of the magnesium alloy sheet are pressed. As the bending head 5 descends, the bending head 5 presses down on the bending point. In the process of pressing down the magnesium alloy sheet, the sliding components 8 on both sides that clamp the magnesium alloy sheet are synchronously gathered toward the middle, so that the bending head 5 is pressed down into the bending groove 9 to complete the bending. In the whole bending process, since the two ends of the magnesium alloy sheet are clamped, one-way movement is avoided. At the same time, the warping of the two ends of the sheet is avoided, thereby improving the quality of the product after bending.

[0037] During specific implementation, when the entire pressing mechanism 6 descends to press the magnesium alloy plate, the upper cross rail 602 is subjected to force, which causes relative sliding between the bolt rod 601 and the two guide rods 604 and the fixed plate 4, and the first spring 603 is compressed, so that the bending head 5 can be pressed down below the upper cross rail 602, so that it can cooperate with the bending groove 9 to bend the magnesium alloy plate.

[0046] The locking nut 805 is sleeved on the connecting rod 802 , and one side of the locking nut 805 is connected to the other end of the second spring 804 .

[0047] In specific implementation, during the bending process, since every two slides 801 clamp one end of the magnesium alloy plate, during the bending process of the magnesium alloy plate, the two ends need to compensate for the length of the bending portion, so that the slide 801 moves along, and during the movement of the slide 801, the connecting rod 802 is pulled, so that the second spring 804 is compressed under the obstruction of the baffle 803 and the locking nut 805. After the bending is completed, the slide 801 can automatically reset when the potential energy of the second spring 804 is released.
