Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bending machine technology, specifically referring to a multi-angle bending machine for aluminum profiles. Background Technology
[0002] An aluminum profile bending machine is a mechanical device specifically used for bending aluminum and aluminum alloy profiles. It applies controllable pressure to cause plastic deformation of the aluminum profile, thereby obtaining a preset angle or complex curved shape.
[0003] The hydraulic cylinders in existing aluminum profile bending equipment are mostly installed at a fixed angle, with a single pushing trajectory. They can only bend the profiles in a preset direction. However, in actual production, the bending requirements for aluminum profiles are complex and diverse. For example, building decoration and furniture components often involve oblique or multi-angle bending, or different sections of the same profile need to be bent in different directions. Since the angle of the hydraulic cylinder cannot be flexibly adjusted, the equipment has poor adaptability. For non-perpendicular bending requirements, special molds need to be customized, which increases costs. Moreover, the same equipment is difficult to be compatible with multi-directional bending tasks, which limits the diversity of product design. Utility Model Content

The top wall of the operating table is provided with a positioning component for limiting the mounting seat.
[0008] Furthermore, the top wall of the movable groove is provided with a fixed shaft between the two sets of limiting wheels, and a swing plate is rotatably provided on the fixed shaft. The top wall of the swing plate is provided with a connecting block that penetrates the deflection groove and is connected to the bottom wall of the mounting base.
[0009] Furthermore, the adjustment assembly includes an adjustment groove and a slider. The adjustment groove is located at one end of the movable groove and is parallel to the connecting groove. A bidirectional lead screw is rotatably provided in the adjustment groove. One end of the bidirectional lead screw passes through the side wall of the adjustment groove and extends out to provide a knob. The slider is slidably disposed in the adjustment groove and is threadedly connected to the bidirectional lead screw. The support block is fixedly connected to the side wall of the slider.
[0010] Furthermore, the positioning component includes a guide groove and a screw. The guide groove is formed on the top wall of the operating table, and a friction block is movably disposed in the guide groove. The screw penetrates vertically through the mounting base and is threadedly connected to the mounting base. The bottom end of the screw is rotatably connected to the top wall of the friction block.
[0011] Preferably, both the guide groove and the deflection groove are arc-shaped structures with a fixed axis as the center.
[0012] Preferably, one end of the mounting base is provided with a pointer, and the top wall of the operating table is provided with an angle mark near the pointer.

[0014] 1. By setting up a swing plate and deflection groove, and cooperating with the mounting base, the deflection angle of the electric push rod can be adjusted, and the friction between the friction block and the guide groove can be adjusted by using the screw, thereby restricting and positioning the mounting base, making it convenient for the top pressing mold to bend aluminum profiles at multiple angles, thereby improving the flexibility of equipment use and meeting the bending needs of various profiles.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.
[0024] like Figure 1-4 As shown, this utility model proposes a multi-angle bending machine for aluminum profiles, including an operating platform 1 with supporting legs at the bottom, and limiting wheels 2 and electric push rods 3 set on the operating platform 1. The output end of the electric push rod 3 is provided with a top pressing die 4 that cooperates with the limiting wheels 2. The profile is placed in front of the two sets of limiting wheels 2, and the electric push rod 3 pushes the top pressing die 4 to move. By limiting the limiting wheels 2 and cooperating with the extrusion of the top pressing die 4, the profile is bent.
[0025] like Figure 2 and 3As shown, it also includes a connecting groove 5 opposite to each other on the top wall of the operating table 1. The operating table 1 is provided with a movable groove 6. The movable groove 6 is provided with a support block 7 set below the connecting groove 5. The limit wheel 2 is installed on the top wall of the support block 7 through the bearing and passes through the movable groove 6. The movable groove 6 is provided with an adjustment component 8 connected to the support block 7 for adjusting the distance between the two sets of limit wheels 2. The adjustment component 8 includes an adjustment groove 15 and a slider 16. The adjustment groove 15 is located at one end of the movable groove 6 and is parallel to the connecting groove 5. A double-acting screw 17 is rotatably provided in the adjustment groove 15. One end of the double-acting screw 17 passes through the side wall of the adjustment groove 15 and extends out to provide a knob 18. The slider 16 is slidably provided in the adjustment groove 15 and is threadedly connected to the double-acting screw 17. The support block 7 is fixed to the side wall of the slider 16.
[0026] Adjust the distance between the two sets of limit wheels 2 according to the profile length and bending angle. Turn the knob 18 to drive the double-acting screw 17 to rotate. The double-acting screw 17 drives the slider 16 to move towards each other along the adjustment groove 15, thereby driving the support block 7 and the limit wheels 2 on the support block 7 to adjust the distance.
[0027] like Figure 1 and 2 As shown, the top wall of the operating table 1 has a deflection groove 9 communicating with the movable groove 6. A mounting base 10 is movably mounted on the deflection groove 9. The electric push rod 3 is mounted on the top wall of the mounting base 10 and is set perpendicular to the connection line of the two sets of limit wheels 2. The top wall of the operating table 1 has a positioning component 11 for limiting the mounting base 10. The top wall of the movable groove 6 has a fixed shaft 12 set between the two sets of limit wheels 2. A swing plate 13 is rotatably mounted on the fixed shaft 12. The top wall of 13 is provided with a connecting block 14 that penetrates the deflection groove 9 and is connected to the bottom wall of the mounting base 10. The positioning component 11 includes a guide groove 19 and a screw 20. The guide groove 19 is opened on the top wall of the operating table 1. A friction block 21 is movably arranged in the guide groove 19. The screw 20 penetrates the mounting base 10 vertically and is threadedly connected to the mounting base 10. The bottom end of the screw 20 is rotatably connected to the top wall of the friction block 21. Both the guide groove 19 and the deflection groove 9 are arc-shaped structures with the fixed shaft 12 as the center.
[0028] Rotating the mounting base 10 causes it to deflect along the deflection groove 9, simultaneously causing the swing plate 13 to rotate around the fixed shaft 12. This causes the mounting base 10 to deflect around the fixed shaft 12 as its center, adjusting the angle of the electric push rod 3. Then, screwing in the screw 20 causes the friction block 21 to move downwards, making it contact the bottom wall of the guide groove 19 and apply pressure to increase friction. This limits the position of the mounting base 10, ensuring the stability of the electric push rod 3 during the bending of the profile.
[0029] like Figure 1 and 4As shown, a pointer 22 is provided at one end of the mounting base 10, and an angle mark 23 is provided on the top wall of the operating table 1 near the pointer 22, so as to facilitate observation of the deflection angle of the mounting base 10 and thus intuitively understand the tilt direction of the electric push rod 3, so as to adjust it for different bending angles.
[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
