[0024] Embodiment

[0025] As Figure 1 shown, a bending device for aluminum processing includes a frame 1 and a cutter head 2 provided on the frame 1. A fixing mechanism for clamping aluminum is provided on the frame 1. The fixing mechanism includes a first guide block 31 fixedly connected to the frame 1. A pressing rod 32 is movably installed inside the first guide block 31. A rubber pressing block 33 is fixedly installed at one end of the pressing rod 32. A locking block 34 is movably installed at the other end of the pressing rod 32. A first connecting rod 35 is movably installed at one end of the locking block 34. A triangular block 36 is movably installed at one end of the first connecting rod 35. A fixing column 37 movably penetrates through the middle of the triangular block 36. A second connecting rod 38 is movably installed at the rear corner of the triangular block 36. A connecting block 310 is movably installed at the lower corner of the triangular block 36. A hydraulic rod 311 is fixedly installed at one end of the connecting block 310. A second guide block 39 is movably installed at one end of the hydraulic rod 311; the length of the second connecting rod 38 is greater than the length of the first connecting rod 35. With this structure, by adopting a fixing mechanism composed of a first guide block 31, a rubber pressing block 33, a first connecting rod 35, a locking block 34, a triangular block 36, a second connecting rod 38, a connecting block 310, and a hydraulic rod 311, etc., the device can effectively clamp and fix the plate-shaped aluminum during bending.

[0026] As Figure 1 and Figure 2As shown in the figure, a support frame 11 is fixedly connected above the frame 1. A first driving mechanism for driving the cutter head 2 to slide longitudinally is provided on the support frame 11. The first driving mechanism includes a transverse rod 41 that is horizontally arranged in the middle of the support frame 11 and is slidably connected to the support frame 11. A lifting motor 42 is provided on the transverse rod 41. A longitudinally arranged longitudinal rack 43 is fixedly provided on the support frame 11. A rotating gear 44 that is meshed and connected to the longitudinal rack 43 is provided on the lifting motor 42. With this structure, by setting the longitudinal rack 43 and the rotating gear 44, under the action of the lifting motor 42, the rotating gear 44 can be driven to rotate around the periphery of the longitudinal rack 43, and then the height of the transverse rod 41 can be adjusted on the support frame 11, thereby driving the height adjustment of the cutter head 2, so as to facilitate the bending of aluminum materials with different thicknesses.

[0027] As Figure 1 and Figure 2 shown in the figure, a second driving mechanism for driving the cutter head 2 to slide transversely is provided on the support frame 11. The second driving mechanism includes two sliding plates 51 that can move up and down along the height direction of the support frame 11 and are symmetrically arranged. A lead screw 52 is rotatably penetrated between the two sliding plates 51. A lead screw nut 53 that is meshed and connected to the lead screw 52 is arranged in the lead screw 52. The lead screw nut 53 is slidably connected to the transverse rod 41. The cutter head 2 is fixedly connected to the bottom of the lead screw nut 53. A moving motor (not shown in the figure) for driving the transmission of the lead screw 52 is provided on the sliding plate 51. With this structure, by setting the lead screw 52 and the lead screw nut 53, under the action of the moving motor, the rotation of the lead screw 52 can be driven, so that the lead screw nut 53 moves back and forth, and then the cutter head 2 can move back and forth on the frame 1, enabling the device to bend plate-shaped aluminum materials with different widths, and having strong practicability.

[0028] As Figure 1 and Figure 2 shown in the figure, the lifting motor 42 is arranged on one side of the support frame 11, and the moving motor is arranged on the side of the support frame 11 away from the lifting motor 42. With this structure, the smoothness of the movement of the cross bar is ensured.

[0029] As Figure 1 and Figure 2As shown in the figure, a stopper 61 is slidably arranged along the length direction on the front side of the frame 1, and the upper end surface of the stopper 61 is higher than the upper end surface of the frame 1; further included is a third driving mechanism for driving the sliding of the stopper 61. The third driving mechanism includes a slide bar 62 fixedly connected to the stopper 61. One end of the slide bar 62 away from the stopper 61 extends into the inner cavity of the frame 1 and is slidably connected to the frame 1. A threaded rod 63 is arranged on the stopper 61, and a fixed seat 64 is arranged on the frame 1. The other end of the threaded rod 63 passes through the fixed seat 64 and is tightened by two lock nuts 65. With this structure, by slidably arranging the stopper 61 along the length direction on the front side of the frame 1, and the upper end surface of the stopper 61 being higher than the upper end surface of the frame 1, a step is formed between the stopper 61 and the frame 1. During the bending operation, the aluminum material is limited by the stopper 61, and thus the distance between the stopper 61 and the frame 1 can be adjusted to facilitate the precise adjustment of the length of the aluminum material extending out of the frame 1, that is, the bending length, thereby reducing the bending error.

[0030] As Figure 1 and Figure 2 shown in the figure, the number of both the slide bar 62 and the threaded rod 63 is 2, and they are symmetrically arranged in pairs on both sides of the frame 1 respectively. With this structure, it is beneficial to limit the aluminum material.

[0031] In this embodiment, scale values are arranged on the slide bar 62. With this structure, it is beneficial to adjust the distance between the stopper 61 and the frame 1 as needed.

[0032] During operation, first, place the aluminum material on the top of the frame 1, loosen the two lock nuts 65, and then adjust the distance between the stopper 61 and the aluminum material. After the distance is adjusted, tighten the lock nuts 65 in the reverse direction on the threaded rod 63, and the fixation of the position between the stopper 61 and the aluminum material is completed.

[0033] Then, the user connects the device to an external power supply, then places the aluminum material on the top of the frame 1, and then the hydraulic rod 311 operates to drive the connecting block 310 to move, driving the triangular block 36 to rotate clockwise. Thus, the triangular block 36 drives the first connecting rod 35 and the second connecting rod 38 to extend outwards to push the lock block 34. The movement of the lock block 34 drives the pressing rod 32 installed at the front end of the frame 1 to rotate clockwise around the connection point with the first guide block 31, and drives the pressing rod 32 installed at the rear end of the frame 1 to rotate counterclockwise around the connection point with the first guide block 31, so that the rubber pressing block 33 presses the aluminum material to position and clamp the aluminum material.

[0034] Next, the moving motor operates. Under the action of the moving motor, the rotation of the lead screw 52 can be driven, enabling the lead screw nut 53 to move horizontally back and forth, and further enabling the lead screw nut 53 to drive the tool head 2 to move to the required position.

[0035] Finally, the lifting motor 42 operates. Under the action of the lifting motor 42, the rotating gear 44 can be driven to rotate around the longitudinal rack 43, and then the transverse rod 41 moves downward on the support frame 11, so as to bend the aluminum material.

[0036] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
