[0002] Aluminum profiles have excellent metal properties such as machinability, formability, corrosion resistance, and recyclability, so they can be bent and used in various fields such as the construction industry, vehicle manufacturing industry, and automated machinery industry. The bending of aluminum profiles requires the cooperation of the punch and the die. Since the punch and the die have a certain degree of protrusion relative to the work surface, the aluminum profile is bent between the punch and the die. When bending the aluminum profile, the positioning of the aluminum profile in the die is prone to errors.

[0003] For example, a patent entitled: A Bending Device for Aluminum Profiles (patent application number: CN202222734326.X) discloses an aluminum profile bending device, in which an aluminum profile plate is placed on a die, and the aluminum profile plate is positioned with the assistance of two positioning devices, and then the driving device is started. The driving device drives the lifting and lowering of the lifting rod through the transmission device, and the lifting and lowering of the lifting rod drives the lifting and lowering of the punch, so that the punch and the die cooperate to bend the aluminum profile plate, and at the same time, the matching wheel fits tightly with the transmission device with the assistance of the spring, which improves the effect and convenience of the equipment. However, the positioning device is fixed, and when the aluminum profile plate is bent, due to the bending deformation, its end will fit on the inner wall of the die, move downward and detach from the positioning device, and there is still an instability problem.

[0004] Therefore, it is necessary to propose a bending machine for aluminum profile processing to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1 to Figure 6 A bending machine for aluminum profile processing shown in the figure includes a base 1, a die groove 2 is provided on the upper surface of the base 1, and slide grooves 3 are provided on both sides of the die groove 2. The inside of the slide groove 3 is slidably connected with a slider 4. In order to improve the sliding stability, the slide groove 3 and the slider 4 are both T-shaped structures, and there is a certain damping sense between the slide groove 3 and the slider 4. When subjected to external force, the slider 4 can slide inside the slide groove 3, and after the external force stops, the slider 4 can stop sliding to avoid random sliding, thereby facilitating the clamping of the aluminum profile plate 5.

[0026] The top of the slider 4 is rotatably connected to an L-shaped frame 6, and a clamping assembly for fixing the aluminum profile plate 5 is arranged on the L-shaped frame 6. The two ends of the aluminum profile plate 5 are respectively fixed to the clamping assemblies on both sides, and the clamping assembly can slide inside the slide groove 3 through the slider 4, so that during the bending process of the aluminum profile plate 5, the aluminum profile plate 5 can always be positioned to improve the processing quality. Moreover, the L-shaped frame 6 is rotatably arranged on the slider 4, and during the bending process of the aluminum profile plate 5, even if the inclination angle of the end of the aluminum profile plate 5 changes, the L-shaped frame 6 can be adaptively rotated.

[0027] In the specific configuration, the clamping assembly includes a stopper 7, a threaded rod 8 and a clamping block 9. The stopper 7 is fixedly connected to the L-shaped frame 6. The stopper 7 is located at one end of the L-shaped frame 6 close to the slider 4. The end of the L-shaped frame 6 away from the slider 4 is threadedly connected with the threaded rod 8. The clamping block 9 is fixedly connected to one end of the threaded rod 8 close to the stopper 7. The end of the aluminum profile plate 5 is positioned between the stopper 7 and the clamping block 9.

[0028] In order to improve the convenience of rotation of the threaded rod 8 , one end of the threaded rod 8 away from the clamping block 9 is fixedly connected with a rotating rod 10 .

[0029] During specific use, the end of the aluminum profile plate 5 is placed between the corresponding stop block 7 and the clamp block 9, and the aluminum profile plate 5 remains in a horizontal state. The threaded rod 8 is rotated by the rotating rod 10 to drive the clamp block 9 to move toward the stop block 7, and the end of the aluminum profile plate 5 is positioned between the stop block 7 and the clamp block 9.

[0030] The top of the base 1 is fixedly connected with a first bracket 11, and a sliding column 12 is penetrated through the top of the first bracket 11, and the sliding column 12 is slidably connected with the first bracket 11. The bottom of the sliding column 12 is fixedly connected with a punch 13, and the punch 13 cooperates with the die groove 2. When the sliding column 12 is pressed downward, the sliding column 12 will drive the punch 13 to move downward synchronously, so that the punch 13 cooperates with the die groove 2 to bend the aluminum profile plate 5.

[0031] Considering the reset of the sliding column 12 and the punch 13 , a spring 14 is sleeved on the outside of the sliding column 12 , one end of the spring 14 is fixedly connected to the first bracket 11 , and the other end of the spring 14 is fixedly connected to the punch 13 .

[0032] The top of the sliding column 12 is rotatably connected with a roller 16, and an extrusion assembly that cooperates with the roller 16 is arranged above the rotating rod 10. The extrusion assembly includes a second bracket 15, a rotating shaft 17, and an eccentric wheel 18. The second bracket 15 is fixedly connected to the top of the first bracket 11, the rotating shaft 17 is rotatably connected to the second bracket 15, and the eccentric wheel 18 is fixedly connected to the rotating shaft 17. The eccentric wheel 18 fits on the roller 16. Since the eccentric wheel 18 is eccentrically arranged relative to the rotating shaft 17, when the eccentric wheel 18 cooperates with the roller 16 and squeezes the sliding column 12 downward, the sliding column 12 drives the punch 13 to move downward synchronously.

[0033] The extrusion assembly further includes a motor 19 , a transmission wheel 20 and a belt 21 . The motor 19 is fixedly connected to the second bracket 15 . The transmission wheel 20 is fixedly connected to the driving shaft of the motor 19 . The transmission wheel 20 is connected to the rotating shaft 17 through the belt 21 .

[0034] During operation, the motor 19 is started, and the motor 19 drives the transmission wheel 20 to rotate. The rotation of the transmission wheel 20 drives the rotating shaft 17 to rotate through the belt 21. The rotation of the rotating shaft 17 drives the eccentric wheel 18 to rotate. When the eccentric wheel 18 cooperates with the roller 16 and squeezes the slide column 12 downward, the slide column 12 drives the punch 13 to move downward synchronously, so that the punch 13 cooperates with the die groove 2 to bend the aluminum profile plate 5.
