[0048] In this embodiment, the disclosed front side clamping module 94 and the rear side clamping module 93 and the clamping module 8 have the same structural design, and their specific structures are as follows: Figure 3 As shown, it includes a clamping base 80, and a screw nut 81 is provided at the bottom of the clamping base 80 to cooperate with the screw, and the screw described here is the lateral screw 71 or the front screw 92 or the rear screw 91.

[0049] Furthermore, in this embodiment, the table tops on the transverse positioning conveying table 5, the transverse working table 7, and the longitudinal working table 9 are ball-bearing table tops or brush table tops. In this embodiment, in order to prevent damage to the plate material, a brush table top is specially used.

[0050] Furthermore, when the utility model is in use, the material must pass through the transverse positioning conveying platform 5, and not only the positioning is achieved on the transverse positioning conveying platform 5, but also the continuous rightward movement is required. Therefore, the utility model has a plurality of horizontal rollers 54 flatly arranged on the transverse positioning conveying platform 5, and the horizontal rollers 54 are connected to the driving device to achieve linkage, so that the transverse drive can be achieved while positioning the plate in the front and back.

[0051] When the utility model is working, after the rolled material 2 passes through the punching machine table 21, it is clamped and positioned front and back by the transverse positioning conveying table 5. During the clamping process, the directional transverse movement of the sheet material can be realized. A cutting table 3 is arranged on the rear side of the transverse positioning conveying table 5 to punch the directionally moved sheet material into sections. At this time, the clamping module 8 clamps the right side of the sheet material and drags the sheet material to the side of the longitudinal moving workbench 9. When it reaches the longitudinal moving workbench 9, the clamping module 8 is stationary. After the front clamping module 94 clamps the sheet material, the clamping module 8 is released, and the front clamping module 94 pushes the sheet material to the rear side. The sheet material reaches the lower part of the bending machine 13, and the rear clamping module 93 clamps the sheet material. At this time, the front clamping module 94 and the rear clamping module 93 jointly clamp the sheet material to the designated bending position, and the front clamping module 94 and the rear clamping module 93 simultaneously fall onto the lower die of the bending machine 13 and then perform the bending operation.

When the plate reaches the lower part of the gantry 6, the flip clamping modules 10 on the two flip assemblies move down and clamp the left and right sides of the plate at the same time, the front clamping module 94 is released and moves forward to avoid, and the flip clamping module 10 moves up to avoid and then flips 180 degrees. After the plate is flipped, the two flip clamping modules 10 move down synchronously and arrive at the longitudinal moving workbench 9. The front clamping module 94 moves backward and clamps the front side of the plate. At this time, the two flip clamping modules 10 are released and move left and right to avoid. The front clamping module 94 pushes the plate to the rear side. The plate reaches the lower part of the bending machine 13. The rear clamping module 93 clamps the plate. At this time, the front clamping module 94 and the rear clamping module 93 jointly clamp the plate to the specified bending position. The front clamping module 94 and the rear clamping module 93 simultaneously fall onto the lower mold of the bending machine 13 and then perform the back bending operation of the plate. After the bending is completed, the air valve blade 1 is formed. If multiple bending parts 11 are provided on each air valve blade 1, multiple cycles can be performed by adjusting the running program. The above running logic can be realized automatically after programming, and the programming language is not limited or constrained here.

[0052] It should be noted that, in the design of the transverse workbench 7, the area on the right side of the bending machine 13 is more than 1.5 meters in length, the purpose of which is to reserve a position for installing a material unloading machine or setting a position for personnel to stand. The unloading machine can be a manipulator of an industrial robot.

[0053] The utility model can realize automatic transverse movement and automatic longitudinal movement of the plate, realize vertical adjustment during the transverse and longitudinal movement, and then realize reverse bending by turning the plate 180 degrees through the turning device.

[0054] The utility model has a novel structural design, can improve the bending efficiency and the bending accuracy, realize automatic operation, overcomes the drawbacks of the prior art, and is an ideal automatic bending production line for air valve fan blades.
