Description

Technical Field

[0001] The invention relates to the technical field of bending devices, and in particular to an aluminum alloy profile bending device and a bending method. Background Art

[0002] In metal structure manufacturing and installation projects, profiles are widely used. Profiles refer to solid straight bars of metal that have been plastically processed and have a certain cross-sectional shape and size. For aesthetics and functional use, some profile parts need to be designed into an arc shape. Therefore, a profile bending device is required to bend the profile into an arc.

[0003] Chinese patent announcement number CN 215614576 U discloses a positioning mechanism for profile bending, including a base, an L-shaped mounting plate fixedly connected to the upper end of the base, an electric push rod installed on the side wall of the mounting plate, an output end of the electric push rod fixedly connected to a first screw, a threaded sleeve threadedly connected to the first screw, one end of the threaded sleeve fixedly connected to a U-shaped positioning frame, a fixing rod fixedly connected to the upper end of the base, a positioning plate fixedly connected to the other end of the fixing rod, a bending cylinder fixedly connected at the center position of the upper end of the positioning plate, and limiting grooves symmetrically provided on the wall of the bending cylinder.

[0004] The positioning mechanism for bending a profile in the above-mentioned patent is provided with a first screw, a threaded sleeve, a positioning frame, a positioning plate, a bending cylinder, a limiting groove, a second screw, a nut, a limiting block, a pressure ring and a first motor. When it is necessary to position profiles of different sizes, the positioning frame of the corresponding size is replaced according to the size of the profile, and the profile is driven to bend by the bending cylinder. However, it can only be bent once, and it is inconvenient to bend the same profile at different angles and positions. For this reason, we provide an aluminum alloy profile bending device, which drives multiple lifting cylinders to move through a bearing seat. Under the action of a bidirectional slide, the profile inserted into the bending frame can be bent under the clamping of a mechanical clamp, and then the rotating motor cooperates with the reducer to drive the rotating seat to rotate, thereby driving the bending frame and the supporting frame to rotate, increasing the bending angle of the profile, and the driving shaft of the sliding motor drives the gear to rotate, so that the moving teeth of the gear meshing angle slide move, and the angle slide moves on the angle slide to adjust the bending direction. It is more convenient to use and effectively compensates for the above-mentioned problems. Summary of the invention

[0005] Technical issues to be solved

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and meet the actual needs.

The rotating motor and the reducer are used to drive the rotating seat to rotate, thereby driving the bending frame and the support frame to rotate, increasing the bending angle of the profile. The driving shaft of the sliding motor drives the gear to rotate, thereby moving the moving teeth of the gear meshing angle slide, and the angle slide moves on the angle slide to adjust the bending direction.
