Description
Technical Field
[0001] The invention relates to the field of aluminum profile processing, and in particular to an aluminum profile bending device. Background Art
[0002] Existing bending devices are often designed with special molds for aluminum profiles of specific specifications and shapes. When it is necessary to process aluminum profiles of different sizes or shapes, operators need to frequently change molds, which not only increases the complexity of operation but also reduces production efficiency. In addition, mold replacement and storage also require additional space and cost.
[0003] For some aluminum profiles that need to adjust the bending angle or shape, the existing bending devices often need to go through a tedious adjustment process. This includes adjusting the working parameters of the device, repositioning the mold, or changing the structure of the device. These adjustment processes are not only time-consuming and labor-intensive, but also prone to introduce errors, affecting the accuracy and stability of the bending. Summary of the invention

[0007] Preferably, the guide wheel includes an inner wheel, a middle ring and an outer ring, the inner wheel is fixedly connected to the outer side of the top end of the rotating shaft, the middle ring is sleeved on the outer side of the inner wheel, the outer ring is sleeved on the outer side of the middle ring, and the guide arm is embedded and fits on one side of the outer ring. By removing the outer ring or the middle ring and the outer ring, the diameter of the guide wheel can be reduced to meet the requirements of smaller bending curvature.
[0008] Preferably, the outer walls of the inner wheel, the middle ring and the outer ring are symmetrically provided with strip grooves, and the side of the guide arm opposite to the clamping arm is also symmetrically provided with strip grooves. These strip grooves are used to fit the shape of the aluminum profile, making the aluminum profile more regular during the bending process.
[0009] Preferably, a positioning plate is fixedly connected to the top of the inner wheel on the outside of the rotating shaft, and a blocking plate is slidably connected to the inside of the positioning plate. By pulling the blocking plate to block the top of the middle ring or the outer ring, the position of the guide wheel during the bending process can be further stabilized to prevent it from shifting or shaking due to uneven force, thereby improving the accuracy and safety of the bending.
[0010] Preferably, the inner wheel, the middle ring and one side of the outer ring are all provided with limiting holes, and one side of the guide arm is provided with a protrusion, which is slidably inserted in the corresponding limiting hole.

After replacing the guide wheel configuration, the connecting plate and the guide arm can be pushed or pulled by rotating the adjusting screw to ensure that the guide arm fits tightly to the adjusted guide wheel.
[0012] Preferably, the top of the synchronous seat is symmetrically and fixedly connected with a guide rail, and the bottom of the movable seat is symmetrically and equidistantly installed with linear motors, which are respectively slidably connected to the outer sides of the corresponding guide rails. The linear motor drives the movable seat to slide along the guide rail, so as to control the separation or adhesion of the clamping arm and the guide arm during the bending process.
[0013] Preferably, the top of the movable seat is symmetrically provided with sliding grooves, and the bottom of the connecting seat is symmetrically fixedly connected with sliders, which are slidably connected inside the corresponding sliding grooves. The sliding connection of the sliders in the sliding grooves provides additional stability and guiding effect for the movement of the clamping arm.
[0014] Compared with the prior art, the advantages of the present invention are as follows:
[0015] 1. The present invention uses a multi-layer guide wheel to flexibly adjust the diameter of the guide wheel according to the bending requirements of the aluminum profile during processing, and easily replace or adjust the configuration of the guide wheel, allowing the user to improve the versatility and adaptability of the device according to different specifications and bending requirements of the aluminum profile.
[0016] 2. The present invention adjusts the design of the screw and the guide column so that the position of the guide arm can be easily fine-tuned to adapt to aluminum profiles of different sizes and shapes. The guide arm fits tightly with the guide wheel, and the cooperation of the limit hole and the protrusion further enhances the stability during the bending process, thereby avoiding slippage or deformation of the aluminum profile.

DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0026] The aluminum profile bending device comprises a body 1;
[0027] like Figures 1 to 7 As shown, a rotating shaft 2 is rotatably connected to one side of the top of the machine body 1, a guide wheel 3 is fixedly connected to the outer side of the top of the rotating shaft 2, a bearing plate 4 is fixedly connected to the outer side of the rotating shaft 2 at the bottom of the guide wheel 3, a guide arm 5 is installed on one side of the bearing plate 4, and the guide arm 5 fits with the guide wheel 3, a synchronous seat 6 is provided on the outer side of the rotating shaft 2, a moving seat 7 is slidably connected to the top of the synchronous seat 6, a support block 8 is fixedly connected to the top of the moving seat 7, a threaded cylinder 9 is fixedly connected to the inside of the support block 8, a threaded rod 10 is threadedly connected to the inside of the threaded cylinder 9, one end of the threaded rod 10 is fixedly connected to a connecting seat 11, and a clamping arm 12 is fixedly connected to the side of the connecting seat 11 close to the guide arm 5;
[0028] Place the aluminum profile to be bent in the working area of the device, and ensure that the bending part of the aluminum profile is exactly between the guide arm 5 and the clamping arm 12. By rotating the threaded rod 10, the threaded rod 10 moves in the threaded cylinder 9, thereby driving the connecting seat 11 and the clamping arm 12 to approach or move away from the guide arm 5. According to the thickness of the aluminum profile, the position of the clamping arm 12 is accurately adjusted so that it can firmly clamp the aluminum profile.
[0029] Start the driving device of the rotating shaft 2, and the rotating shaft 2 begins to rotate. Since the guide wheel 3 is fixed at the top of the rotating shaft 2, the guide wheel 3 also rotates with the rotating shaft 2. During the rotation of the rotating shaft 2, the guide arm 5 and the clamping arm 12 rotate together with the rotating shaft 2. Since the guide arm 5 fits tightly against the guide wheel 3 and the clamping arm 12 firmly clamps the aluminum profile, the aluminum profile will bend and deform along the shape of the guide wheel 3.
[0030] like Figures 1 to 7 As shown, the guide wheel 3 includes an inner wheel 31, a middle ring 32 and an outer ring 33. The inner wheel 31 is fixedly connected to the outer side of the top end of the rotating shaft 2, the middle ring 32 is sleeved on the outer side of the inner wheel 31, and the outer ring 33 is sleeved on the outer side of the middle ring 32. The guide arm 5 is embedded and attached to one side of the outer ring 33.
[0031] According to the required bending curvature of the aluminum profile, an appropriate guide wheel 3 configuration is selected. The guide wheel 3 is composed of a multi-layer structure, including an inner wheel 31, a middle ring 32 and an outer ring 33. When a smaller bending curvature is required, the outer ring 33 or the middle ring 32 and the outer ring 33 can be removed.
[0032] like Figures 1 to 7 As shown, the outer walls of the inner wheel 31, the middle ring 32 and the outer ring 33 are symmetrically provided with strip grooves 34, and the side of the guide arm 5 opposite to the clamping arm 12 is also symmetrically provided with strip grooves 34. The strip grooves 34 are used to fit the shape of the aluminum profile, so that the aluminum profile is more regular during the bending process.
[0033] like Figures 1 to 7 As shown, a positioning plate 13 is fixedly connected to the top of the inner wheel 31 on the outside of the rotating shaft 2, and a blocking plate 14 is slidably connected inside the positioning plate 13. By pulling the blocking plate 14 to block the top of the middle ring 32 or the outer ring 33, the guide wheel 3 can be made more stable during the bending process.
[0034] like Figures 1 to 7 As shown, the inner wheel 31, the middle ring 32 and the outer ring 33 are all provided with limiting holes 35 on one side, and the guide arm 5 is provided with a protrusion 36 on one side. The protrusion 36 is slidably inserted into the corresponding limiting hole 35, and the protrusion 36 is inserted into the limiting hole 35 to make the guide arm 5 smoother during the bending process of fitting the aluminum profile.
[0035] like Figures 1 to 7As shown, a connecting piece 15 is fixedly connected to the bottom of the guide arm 5, a fixing piece 16 is fixedly connected to the bottom of the carrier plate 4, an adjusting screw 17 is threadedly connected inside the fixing piece 16, one end of the adjusting screw 17 is rotatably connected to the connecting piece 15, a guide post 18 is symmetrically slidably connected inside the fixing piece 16, one end of the guide post 18 is fixedly connected to the connecting piece 15, and after replacing the configuration of the guide wheel 3, the position of the guide arm 5 needs to be adjusted by the adjusting screw 17. Rotate the adjusting screw 17 to push or pull the connecting piece 15 and the guide arm 5 to ensure that the guide arm 5 is tightly fitted to the adjusted guide wheel 3.
[0036] like Figures 1 to 7 As shown, the top of the synchronous seat 6 is symmetrically fixedly connected with a guide rail 19, and the bottom of the moving seat 7 is symmetrically installed with linear motors 20, which are slidably connected to the outside of the corresponding guide rails 19. The linear motors 20 drive the moving seat 7 to slide along the guide rails 19 to control the separation or adhesion of the clamping arm 12 with the guide arm 5 during the bending process.
[0037] like Figures 1 to 7 As shown, the top of the movable seat 7 is symmetrically provided with slide grooves 21, and the bottom of the connecting seat 11 is symmetrically fixedly connected with sliders 22, which are slidably connected inside the corresponding slide grooves 21, and the sliding of the sliders 22 in the slide grooves 21 provides additional stability and guiding effects.
