Description

Technical Field

[0002] Aluminum alloy profiles are commonly used metal structural materials with wide applications and play a crucial role in industrial development. In the fields of construction, aerospace, automotive, electronic products, etc., the application of aluminum alloy profiles can be seen. In the production of aluminum alloy profiles, there are various processing procedures. Currently, aluminum alloy profiles are generally bent according to requirements, that is, the profiles are bent and deformed to process the required external shape structure. The existing bending devices generally require manual placement of the profiles in the bending area, and through the movement of the profiles and the extrusion of the bending rollers, the bending operation is finally completed. During this process, when manually placing the profiles, positioning operations are required, and the process is relatively cumbersome. In addition, for different requirements, the bending radius will be different. When the current bending equipment needs to change the bending radius, the bending support part needs to be replaced, and the operation is cumbersome, which is not conducive to the processing efficiency. Based on this, the present invention proposes a bending device for aluminum alloy profiles with automatic positioning, which can complete the positioning operation before bending.

A radial sliding seat 37 is radially slidably arranged on the mounting and regulating table 29. A pushing electric cylinder 31 is arranged on the radial sliding seat 37. The pushing electric cylinder 31 passes through a cross connecting rod 3801 to push telescopic bending support parts 38 with different diameters. A radial lead screw 36 is fixedly arranged on the radial sliding seat 37. A meshing gear 35 is rotatably arranged on the mounting and regulating table 29. The meshing gear 35 and the control gear ring 32 form a gear pair, and the meshing gear 35 and the radial lead screw 36 form a screw pair.

[0037] Working principle: First, manually place the profile from the side of the working platform 1 into the transposition placing cylinder 39, that is, place the profile into the slot, and limit and fix it through the fixing member. Specifically, after the profile enters the slot, it squeezes and pushes the buckle seat 45, causing the buckle seat 45 to slide and the spring 47 to compress. When the profile completely enters the slot, the buckle seat 45 rebounds under the elastic force of the spring 47 to fix the profile. By the operation of the transposition placing motor 4, under the gear drive, the transposition placing cylinder 39 rotates, and then the profiles are sequentially placed in the slots. Then, the profiles can be sequentially transferred to the position where the guiding member is located through the clamping members on the transfer mounting frame 3901. Since the profiles are positioned and fixed in the slots, when the profiles are transferred to the guiding place, automatic positioning can be realized, saving the cumbersome calibration operation when manually installing the profiles.

[0038] When transferring profiles, the clamping transfer oil cylinder 40 works. The installed clamping seat 42 moves to both sides of the profile, and the profile is clamped by the clamping and fixing oil cylinder 41. At the same time, the electromagnetic push rod 43 works, and the end of the electromagnetic push rod 43 pushes the push seat 46, causing the buckle seat 45 to slide, thereby releasing the limit fixation of the profile. The profile is transferred to the position where the guiding member is located, and one end of the profile is clamped by the clamping oil cylinder 6. The profile is located between the opposing guiding rollers 14. That is, by the guiding control motor 2 working, the second lead screw 10 rotates, causing the guiding platform 11 to slide, and then the profile is limited by the guiding rollers 14. By the jacking electric cylinder 31 working, the guiding rollers 14 can be rotated. By the first motor 8 working, the first lead screw 9 rotates, causing the pushing platform 5 to slide to push the profile.

[0039] When performing bending, different diameters of telescopic bending support parts 38 can be selected as the bending support according to the bending requirements to obtain different bending radii. Specifically, the control motor 33 works. Under gear transmission, the control gear ring 32 rotates, and the meshing gear 35 also rotates. Under the connection of the screw pair, the radial lead screw 36 moves, thereby adjusting the radial positions of the radial slide seat 37 and the jacking electric cylinder 31. The jacking electric cylinder 31 jacks different diameters of telescopic bending support parts 38. For example, when jacking the telescopic bending support part 38 with the smallest diameter, the telescopic rod of the jacking electric cylinder 31 passes through the bottom of the telescopic bending support parts 38 with other diameters, that is, through the cross connecting rod 3801, to push the bottom of the target telescopic bending support part 38. Further, if other diameters of telescopic bending support parts 38 are needed, by jacking the bottom of the target telescopic bending support part 38, the other telescopic bending support parts 38 inside the target telescopic bending support part 38 will move together with the target telescopic bending support part 38, and the target telescopic bending support part 38 serves as the bending support.

[0040] After selecting different bending supports, the support position needs to be calibrated. That is, by the adjusting motor one 2501 working, the first adjusting lead screw 25 rotates, and the first adjusting seat 26 slides to complete the calibration of the height position. By the adjusting motor two 28 working, the second adjusting lead screw 27 rotates, and then the installed adjusting table 29 slides to complete the calibration of the horizontal position, so that after the bending area of the profile reaches the support area, the surface of the profile can be aligned with the support area. Further, the bending position of the bending roller 24 also needs to be calibrated. By the motor two 18 working, the third lead screw 19 rotates, causing the adjusting seat 20 to move to complete the calibration operation. By the motor three 21 working, the fourth lead screw 22 rotates, and the bending sliding platform 23 moves, and then the profile is bent by the bending roller 24 to complete the bending operation.
