[0035] The aluminum material processing bending mechanism in the embodiment adopts a combined structure for the concave die 3, which is composed of the inner mold 301 and a plurality of outer molds 302 with increasing inner diameters and in sliding connection with each other, and through the adjusting mechanism 5, the position of the outer mold 302 can be conveniently and quickly regulated and controlled, the switching of different bending radii is realized, compared with the traditional mold replacement mode, the complicated disassembly and installation process is not needed, and the operation is simple and efficient; the convex die 4 and the concave die 3 can perform multi-angle lateral bending on the aluminum material, increase the flexibility of bending, and meet the aluminum material processing requirements of different shapes and structures; the concave die 3 adopts a combined structure, which is composed of the inner mold 301 and a plurality of outer molds 302 with increasing inner diameters, the bending space can be changed, so that the regulation of different bending radii is realized, the bending of aluminum materials of different specifications is adapted, the trouble of replacing molds is reduced, and the processing efficiency is improved; through the adjusting mechanism 5, the next outer mold 302 can also be raised after the switching of the outer mold 302, the clamping state of the aluminum material is continuously maintained, and the stability of the aluminum material in the bending process is ensured.

[0036] The working principle of the above embodiment is as follows:

[0037] First, the aluminum material to be bent is placed between the male die 4 and the female die 3. In the initial state, the male die 4 and the clamp 2 are at the same horizontal plane. When the aluminum material is located between the male die 4 and the inner die 301 of the female die 3, the two cylinders 802 are started to drive the male die 4 and the clamp 2 to move towards the inner die 301, so that the male die 4 and the clamp 2 cooperate with the inner die 301 to clamp the aluminum material. Then the motor drives the bevel gear A to rotate, the bevel gear A drives the bevel gear B to rotate, the bevel gear drives the support seat 102 to rotate, the support seat 102 can not only drive one of the connecting frames 801 to rotate around the support seat 102 as the axis, but also drive the slide rail 6 to rotate, the slide rail 6 drives the center shaft 9 to rotate, and the center shaft 9 drives the inner die 301 to rotate. Since the female die 3 is in the shape of "6", the structure characteristics enable the outer die 302 and the inner die 301 to rotate synchronously. Since the cylinder 802 rotates around the support seat 102 as the axis with one of the connecting frames 801, the male die 4 can also rotate around the support seat 102 as the axis. With the synchronous rotation of the male die 4 and the inner die 301, the aluminum material can be bent.

[0038] Then, the outer die 302 contacts the upper surface of the support seat 102. Before bending, the electric push rod 503 can be started to drive the sleeve 504 to rise, the sleeve 504 drives the two U-shaped plates 501 to rise, and the U-shaped plates 501 can control the outer die 302 in the innermost layer to rise. The distance between the outer die 302 in the innermost layer and the protruding part of the inner die 301 can be adjusted to adapt to aluminum materials of different widths. The outer die 302 in the innermost layer and the protruding part of the inner die 301 can clamp the aluminum material again to improve the stability in the subsequent bending process and prevent the aluminum material from shifting.

[0039] Then, when the bending radius of the aluminum material needs to be increased, the biaxial electric push rod 502 can be used to control the two push-pull rods 7 to move away from each other, drive the two U-shaped plates 501 to move away from each other, and move the U-shaped plates 501 to the outer die 302 matching the bending radius. Then the rising of the U-shaped plates 501 is controlled to control the rising of the outer die 302 until the outer die 302 is in contact with the protruding part of the inner die 301. The contact surface of the outer die 302 should be treated to prevent slipping. The friction between the two can fix the position of the outer die 302 after rising by friction. The protruding part of the inner die 301 can also be designed as a magnet structure, and the outer die 302 is made of metal material. The magnetic force can further strengthen the fixing force between the two. When the outer die 302 needs to be reset, it only needs to be pulled down. It is convenient and fast. Since the inner diameter of the outer die 302 increases in turn, the height of the outer die 302 is adjusted, and then the bending process is performed, different bending radii can be achieved. Through the adjusting mechanism 5, the next outer die 302 can also be raised after switching the outer die 302 to continue to maintain the clamping state of the aluminum material, ensuring the stability of the aluminum material during the bending process.

[0040] It should be noted that in the process of bending aluminum material, cracks and wrinkles are more common, and frequent adjustment of the bending radius can help find the processing parameters suitable for aluminum material and reduce the defect rate. Since the size of the concave die 3 is fixed, if different radius aluminum materials are to be bent, the bolts or clamps 2 fixing the die need to be loosened with professional tools first, then the die suitable for the new bending radius is moved to the installation position, and is preliminarily positioned through the positioning pins or positioning holes. Finally, the bolts are tightened and the clamps 2 are clamped to complete the fixing. The operation is complicated, not only time-consuming and laborious, but also seriously affects the bending efficiency. However, the bending mechanism only needs to control the position of the outer die 302 through the adjusting mechanism 5, which quickly adapts to different radius bending requirements, is simple to operate, saves time and effort, and can greatly improve the bending efficiency.
