An adsorption disk array 4 is installed on the upper clamping frame 3, and the adsorption disk array 4 adsorbs the clamped processing material. The upper clamping frame 3 fixes and supports the processing material through the adsorption disk array 4 to prevent the processing material from running off during processing. A roller groove 21 is opened on the lower clamping frame 2, and a pushing roller 5 is installed in the roller groove 21. The pushing roller 5 pushes the processing material to move and move towards the flexible bending center.

[0023] In this embodiment, limiting plates 22 are symmetrically arranged at both ends of the lower clamping frame 2. The limiting plates 22 limit the movement path of the upper clamping frame 3. A limiting groove 221 is opened on the limiting plates 22, and the limiting groove 221 is movably connected to the upper clamping frame 3. The lower end of the limiting plate 22 is fixedly connected to a first insertion cylinder 222, and a first gear 23 is movably connected to the first insertion cylinder 222.

[0024] In this embodiment, a first eccentric shaft 231 is arranged on the side of the first gear 23 connected to the first insertion cylinder 222. The first eccentric shaft 231 is inserted into the first insertion cylinder 222. The central axis of the first gear 23 is connected to the clamping motor 11. When the clamping motor 11 rotates, it drives the first gear 23 to rotate, and the first eccentric shaft 231 drives the lower clamping frame 2 to move up or down to approach or move away from the upper clamping frame 3.

[0025] In this embodiment, sliding blocks 31 are fixedly connected to both ends of the upper clamping frame 3. The sliding blocks 31 are engaged with the limiting grooves 221. A second insertion cylinder 311 is arranged on one side of the sliding blocks 31, and a second gear 32 is movably connected to the second insertion cylinder 311. The second gear 32 meshes with the first gear 23. The central axis of the second gear 32 is movably connected to the motor base 1. The first gear 23 drives the second gear 32 to rotate, and the second gear 32 controls the up and down movement of the upper clamping frame 3.

[0026] In this embodiment, a second eccentric shaft 321 is provided on one side of the second gear 32 connected to the upper clamping bracket 3. The second eccentric shaft 321 is inserted into the second insertion cylinder 311. When the second gear 32 rotates, the height position of the second eccentric shaft 321 changes, and the second eccentric shaft 321 rotates within the second insertion cylinder 311, driving the upper clamping bracket 3 to move up or down.

[0027] In this embodiment, a suction cup body 41 is provided at a position where the suction cup array 4 is placed below the upper clamping bracket 3. The upper sides of the suction cup bodies 41 are commonly connected by a pipeline to a vacuum pump 42.

[0028] In this embodiment, both ends of the pushing roller 5 are movably connected to the roller groove 21 through rotating shafts. A belt groove 51 is provided at one end of the pushing roller 5.

The pushing roller 5 pushes the processing material to enter the bending position of the flexible bending center. Turn off the driving motor 53, and the clamping motor 11 operates to drive the first gear 23 to rotate. The second gear 32 rotates in the opposite direction to the first gear 23, and the lower clamping bracket 2 and the upper clamping bracket 3 move towards each other to clamp the processing material. The suction cup body 41 on the upper clamping bracket 3 contacts the processing material, and the vacuum pump 42 evacuates the air to adsorb and fix the processing material. At this time, bending is performed, and the processing material cannot move. After one bending is completed, the suction cup body 41 releases the processing material, and the lower clamping bracket 2 and the upper clamping bracket 3 move away. The driving motor 53 further pushes the processing material for secondary bending.

[0030] In summary: A clamping device for a flexible bending center with high adsorption of the present utility model drives the processing material to move towards the flexible bending center through the pushing roller 5, can perform multiple bending operations, and during bending, the lower clamping bracket 2 and the upper clamping bracket 3 clamp the processing material, and the suction cup body 41 adsorbs at a fixed point to firmly fix the position of the processing material, preventing the displacement of the processing material, increasing the stability during the processing, improving the processing accuracy, and reducing the workpiece damage caused by improper clamping.
