[0028] The chassis 1 is fixed with a frame 11, and a control panel 12 is installed at one end of the frame 11. The control box 2 is electrically connected to the control panel 12;

[0029] The punch assembly 3 includes a bottom plate 31, a lower mold plate 32 is symmetrically arranged above the bottom plate 31, and a plurality of punch mold plates 33 are arranged above the lower mold plate 32.

Specifically, the arc-shaped plate passes through the auxiliary pressure wheel 41 and the lower template 32, and the lower pressure plate 35 drives the fixed block 45 on the reinforcement shaft 34 to move downward, so that the auxiliary pressure wheel 41 under the fixed block 45 presses down the arc surface of the arc processing plate 8, so that the arc processing plate 8 is stably placed in the lower template 32.

The lower pressure plate 35 continues to move downward, and the auxiliary pressure wheel 41 is subjected to the reaction force to compress the spring 44 through the auxiliary pressure frame 43, so that the auxiliary wheel 41 enters between the convex templates 33, and the convex template 33 continues to move downward to perform a bending operation on the arc processing plate 8. Example 2

[0033] Based on the above embodiment 1, please refer to the attached Figure 2 、 Figure 3 、 Figure 6 as well as Figure 7 The hydraulic assembly 6 includes an oil tank 61 , which is connected to a reversing valve 63 and an oil pump 64 through an oil pipe 62 , and the oil pump 64 is connected to the reversing valve 63 through an oil pipe 62 .

[0034] The reversing valve 63 is connected to the upper and lower parts of the oil cylinder 65 through the oil pipe 62. Two oil cylinders 65 are symmetrically provided. The oil cylinder 65 is provided with a hydraulic shaft 66. The hydraulic shaft 66 passes through the support plate 51. The oil cylinder 65 is fixed to the bottom surface of the support plate 51. Specifically, the oil pump 64 draws hydraulic oil 66 from the oil tank 61 to the reversing valve 63. The hydraulic oil 66 passes through the reversing valve 63 to reach the lower part of the oil cylinder 65, and then pushes the hydraulic shaft 66 upward.

[0035] The transmission assembly 7 includes a central shaft 71, both ends of which are rotatably engaged with the inner wall of the control box 2. Two rotating racks 72 are rotatably engaged with the central shaft 71. One end of the rotating rack 72 is rotatably engaged with the transmission shaft 73. One end of the transmission shaft 73 is rotatably engaged with a U-shaped rack 74. The U-shaped rack 74 is fixedly connected to one end of the hydraulic shaft 66.

[0036] A linkage plate 75 is rotatably engaged at one end of the rotating frame 72 , and the other end of the linkage plate 75 is rotatably connected to a connecting plate 76 . The connecting plate 76 is screwed to the upper end of the lower pressing plate 35 , and the lower pressing plate 35 is slidably engaged between the symmetrically arranged side plates 77 .

[0037] The convex mold plates 33 are connected by a reinforcing shaft 34 , which is connected to a fixed block 45 . The bottom surface of the rubber friction plate 56 is at the same height as the top surface of the lower mold plate 32 . An arc-shaped processing plate 8 is provided between the auxiliary pressure wheel 41 and the lower mold plate 32 .

[0038] In this embodiment, the hydraulic shaft 66 utilizes the U-shaped frame 74 to drive the transmission shaft 73, and then drives the rotating frame 72 to rotate around the central axis 71, so that the other end of the rotating frame 72 moves downward, and then drives the linkage plate 75 to act on the connecting plate 76, and then drives the lower pressure plate 35 to slide up and down between the side plates 77.

[0039] The working principle and use process of the present invention are as follows: first, the curved plate passes between the auxiliary pressure wheel 41 and the lower template 32, and the bending process is started by inputting the bending program through the control panel 12. The control box 2 first starts the oil pump 64 to extract hydraulic oil 66 from the oil tank 61 to the reversing valve 63. At this time, the two reversing valves 63 connected to the lower half of the oil cylinder 65 are in the open state. The hydraulic oil 66 passes through the reversing valve 63 to reach the lower part of the oil cylinder 65, and then pushes the hydraulic shaft 66 upward;

[0040] Then the hydraulic shaft 66 uses the U-shaped frame 74 to drive the transmission shaft 73, and then drives the rotating frame 72 to rotate around the central axis 71, so that the other end of the rotating frame 72 moves downward, thereby driving the linkage plate 75 to squeeze the connecting plate 76 downward, and then drives the lower pressure plate 35 to slide downward between the side plates 77. The lower pressure plate 35 drives the fixed block 45 on the reinforcing shaft 34 to move downward, thereby causing the auxiliary pressure wheel 41 under the fixed block 45 to press down the curved surface of the curved processing plate 8, so that the curved processing plate 8 is stably placed in the lower template 32, and the curved surface to be bent faces the convex template 33 above, thereby ensuring the quality of the subsequent curved processing plate 8 during processing;

[0041] At the same time, the servo motor 55 is started to drive the motor gear 54 to rotate counterclockwise, and the motor gear 54 drives the displacement plate 52 to move to the lower template 32 through the serrated rod 53, thereby driving the rubber friction plate 56 to form a support for one side of the arc processing plate 8, further strengthening the placement stability of the arc processing plate 8. At this time, the lower pressure plate 35 continues to move downward, and the auxiliary pressure wheel 41 is subjected to the reaction force. The auxiliary pressure frame 43 compresses the spring 44 to make the auxiliary wheel 41 enter between the convex template 33, and the convex template 33 continues to move downward to bend the arc processing plate 8, and then the reversing valve 63 connected to the upper half of the oil cylinder 65 in the two reversing valves 63 is opened, so that the lower pressure plate 35 runs upward, and the servo motor 55 continues to drive the rubber friction plate 56 to move forward, thereby frictionally acting on the arc processing plate 8, and cooperating with the rotation effect of the auxiliary pressure wheel 41 to translate, so that the arc processing plate 8 reaches the next bending position, realizing precise bending operation, which is highly practical.
