[0002] A flanging mechanism is a common mechanical processing equipment used to apply pressure to the edges of metal sheets or other materials to form the required shapes or processing features. With the progress of industrialization, the requirements for production efficiency and processing accuracy are constantly increasing, and the flanging mechanism, as an important processing equipment, has gradually been developed and applied.

[0003] The prior art includes: the material of the flanging wheel, using wear-resistant and high-hardness materials such as cemented carbide or ceramics; the pressure transmission system, using hydraulic, pneumatic or mechanical transmission systems to control the magnitude and duration of the flanging force, and selecting a suitable system according to needs; the control system, equipped with an advanced numerical control system to achieve precise control of the flanging force and adjustment of processing parameters, with simple operation; the intelligent technology, integrating sensor and data analysis technologies to achieve real-time monitoring and automatic adjustment of processing parameters, improving processing efficiency and consistency.

[0004] However, in the existing equipment, the distance between the two flanging wheels is fixedly connected to the lower part of the lifting structure. This installation method causes the need to use tools to remove the fixing structure of the two flanging wheels and then reinstall them when changing the distance between the two flanging wheels during the use of the machine.

[0026] Working principle: When using this equipment, place the workpiece in the middle of the workbench 11, and then the workbench 11 can clamp and rotate the workpiece. Then start the first motor 4, and the first motor 4 will drive the first threaded rod 5 to rotate. The rotation of the first threaded rod 5 will drive the second slider 8 to move upward. At this time, the second slider 8 will pull the two connecting rods 9 to move, and the two connecting rods 9 can pull the two first sliders 7 to move towards the middle. When the distance between the two edge pressing wheels 10 is adjusted appropriately, stop the first motor 4, and then start the air cylinder 2.

When the first motor 4 is started, the second motor 15 will also be started. At this time, the second motor 15 will drive the worm 16 to rotate. After the worm 16 rotates, it will drive the worm gear 17 to rotate. The worm gear 17 can drive the second threaded rod 18 to rotate, and the second threaded rod 18 can push the protective cover 12 to move upward. When the two limit plates 13 abut against the bottom of the limit groove, the second motor 15 stops. Thus, the protection of the machine and workers by the protective cover 12 can be realized. After the workpiece processing is completed, the second motor 15 and the air cylinder 2 are started simultaneously. At this time, the protective cover 12 will descend and be embedded in the up-down groove, the lifting block 3 will rise away from the workpiece, the workbench 11 will stop rotating and release the workpiece, and the worker can place a new workpiece in the middle of the workbench 11. Thus, the continuous processing of the workpiece can be realized.
