[0018] See also Figure 1-3 , an aluminum profile bending machine, comprising a processing table 1, a rotating base 2 is fixedly installed at the corner of the processing table 1, a bending base block 3 is rotatably installed on the top of the rotating base 2, a bending flip plate 4 coaxial with the bending base block 3 is rotatably connected to the rotating base 2, and the bending base block 3 is in contact with the outer wall of the end side of the processing table 1, a traverse substrate 5 is slidably arranged on the processing table 1, and a side of the processing table 1 corresponding to the traverse substrate 5 is provided with a compensation mechanism 6, the bending flip plate 4 and the traverse substrate 5 are respectively connected to an extrusion fixed block 7 and an extrusion fixed block 8 facing the bending base block 3 through a cylinder, and the extrusion fixed block 7 and the extrusion fixed block 8 are respectively connected to the bending base block 3 through a cylinder. The pressure fixing blocks 2 8 are fitted to each other, an integrated solid material protrusion 9 is fixed in the middle of the outer surface of the bending base block 3, and an integrated solid material protrusion 9 is also fixed in the middle of the side outer wall of the extrusion fixing block 1 7 and the extrusion fixing block 2 8 close to the bending base block 3. The bending base block 3 is aligned at the same height as the extrusion fixing block 1 7 and the extrusion fixing block 2 8, and an open circular tube slot 10 is opened in the middle of the corresponding solid material protrusion 9 of the bending base block 3. The extrusion fixing block 1 7 and the extrusion fixing block 2 8 also have an open circular tube slot 10 in the middle of the corresponding solid material protrusion 9, and the cross-section of the circular tube slot 10 is an isosceles trapezoid flipped 90 degrees.

[0019] The cross-section of the round tube slot 10 is semicircular. When bending the round tube aluminum profile, half of the round tube aluminum profile can be first placed and clamped in the round tube slot 10 opened by the solid material protrusion 9 on the bending base block 3, and then the round tube aluminum profile is fixed by squeezing the fixing block 1 7 and the fixing block 2 8. Then, the round tube aluminum profile is bent by driving the rotating base 2, and the round tube slot 10 is opened by the solid material protrusion 9 on the bending base block 3 and the solid material protrusion 9 on the fixing block 1 7 and the fixing block 2 8. When the round tube slot 10 is semicircular, it can directly fit the outer surface of the round tube aluminum profile, but the round tube slot 10 is an isosceles trapezoid flipped 90 degrees. The round tube aluminum profile can also be fixed by the top inclined surface and the bottom inclined surface of the round tube slot 10 being tangentially fitted with the round tube aluminum profile.

[0020] The length of the extrusion fixing block 2 8 is greater than that of the extrusion fixing block 1 7. The transverse moving base plate 5 is U-shaped, and two groups of cylinders on both sides are installed on the transverse moving base plate 5 for connecting the extrusion fixing block 2 8. The fitting part of the extrusion fixing block 1 7 and the extrusion fixing block 2 8 is opposite to the middle vertical line of the bending base block 3.

[0021] A limiting slide groove 12 is provided on the top outer wall of the bending and flipping plate 4 and the transverse base plate 5 , and a limiting slider 11 which is integrally slidably engaged in the limiting slide groove 12 is fixed to the bottom of the extrusion fixing block 1 7 and the extrusion fixing block 2 8 .

[0022] The compensation mechanism 6 includes a limiting slide block 13, a limiting slide groove 14 and a compensation cylinder 15. A limiting slide groove 14 is provided on the top outer wall of the processing table 1 on the side close to the bending and flipping plate 4. An integrated limiting slide block 13 is fixedly provided on the bottom outer wall of the side of the traverse substrate 5 away from the bending and flipping plate 4, and a compensation cylinder 15 is fixedly installed in the corresponding limiting slide groove 14 of the processing table 1. The piston shaft end of the compensation cylinder 15 is connected to the traverse substrate 5. The side outer wall is fixedly connected, and at the same time, the limiting slider 11 at the bottom of the extrusion fixing block 17 and the extrusion fixing block 2 8 is slidably engaged with the limiting slide groove 12 on the bending flip plate 4 and the transverse moving base plate 5, so that the extrusion fixing block 17 and the extrusion fixing block 2 8 can be limited when they are transversely moved to ensure that there is no deflection during displacement. At the same time, the limiting slider 2 13 at the bottom of one side of the transverse moving base plate 5 is slidably engaged with the limiting slide groove 2 14, which is also to limit the transverse moving base plate 5 when it is transversely moved to ensure that there is no deflection.

[0023] Working principle: When the I-shaped aluminum profile is bent, the I-shaped aluminum profile is first placed horizontally between the bending base block 3 and the extrusion fixing block 1 7 and the extrusion fixing block 2 8 on the same side, and the side depression of the I-shaped aluminum profile is clamped with the solid material protrusion 9 on the outer wall of the bending base block 3, and then the cylinder on the bending flip plate 4 and the horizontal movement base plate 5 are synchronously driven to drive the extrusion fixing block 1 7 and the extrusion fixing block 2 8 to move closer to the bending base block 3, and make the solid material protrusion 9 on the extrusion fixing block 1 7 and the extrusion fixing block 2 8 close to the depression on the other side of the I-shaped aluminum profile. In the process, the bending base block 3 is squeezed by the extrusion fixing block 1 7 and the extrusion fixing block 2 8 so that the I-shaped aluminum profile can be fixed, and then the rotating base 2 can be driven to drive the bending base block 3 and the bending flip plate 4 to flip, and the extrusion fixing block 1 7 on the bending flip plate 4 can cooperate with the bending base block 3 to bend the aluminum profile. At the same time, when the aluminum profile is bent as the bending base block 3 rotates, the compensation cylinder 15 is synchronously driven to push the transverse base plate 5 to move horizontally, so that the profile part fixed by the extrusion fixing block 2 8 moves forward to cooperate with the bending of the aluminum profile. At the same time, by sliding and engaging the limiting slider 11 at the bottom of the extrusion fixing block 17 and the extrusion fixing block 2 8 with the limiting slide groove 12 on the bending flip plate 4 and the transverse moving substrate 5, the extrusion fixing block 17 and the extrusion fixing block 2 8 can be limited when they move horizontally to ensure that there is no deflection during displacement. At the same time, the limiting slider 2 13 at the bottom of one side of the transverse moving substrate 5 is slidably engaged with the limiting slide groove 2 14, which can also limit the transverse moving substrate 5 when it moves horizontally to ensure that there is no deflection.

[0024] When bending the round tube aluminum profile, half of the round tube aluminum profile can be first placed and clamped in the round tube clamping groove 10 opened on the solid material protrusion 9 on the bending base block 3, and then the above steps are repeated to extrude and fix the round tube aluminum profile through the extrusion fixing block 1 7 and the extrusion fixing block 2 8. Then, the round tube aluminum profile is bent by driving the rotating base 2, and the round tube clamping groove 10 is opened through the solid material protrusion 9 on the bending base block 3 and the solid material protrusion 9 on the extrusion fixing block 1 7 and the extrusion fixing block 2 8, so that the aluminum profile bending machine is not only suitable for I-shaped aluminum profiles but also for round tube aluminum profiles, thereby improving the applicability and functionality of the aluminum profile bending machine and improving the operating convenience of the aluminum profile bending machine.
