The bottom end of the top plate 1 is equipped with a frame 26, and the bottom end of the frame 26 is in contact with the ground for support.

[0034] More specifically, the support adjustment mechanism is adjusted according to the bending and material requirements. A suitable adjustment hole 23 position is selected, and each component is fixed using a snap-fit ​​system. The working status of the guide system is checked. The bending material is installed onto the mounting push plate 3, confirming that the material matches the fixed support 4. The position of the guide wheel 6 is adjusted to ensure accurate guidance. The hydraulic cylinder 2 is activated to push the material forward. The material is guided by the guide wheel 6 system and, upon reaching the bending position, the motor is activated. The bending frame 12 reciprocates, pressing against both ends of the material. Feeding continues according to the crease requirements, with the motor system working in tandem. The longitudinal sleeve 17 is fixed using the locking clamp 601, the guide block 25 ensures the movement accuracy of the lead screw frame 18, and the frame 26 provides stable support.

[0035] In summary, during the use or operation of the overall equipment: when the hydraulic feeding mechanism is required, the hydraulic cylinder 2 drives the mounting push plate 3 to transport materials. During operation, the bent material is fixed on the mounting push plate 3, and the hydraulic cylinder 2 pushes the material forward. The fixed support frame 4 provides support and guidance for the material at the top of the top plate 1. After passing through the fixed support frame 4, the material is guided by the guide wheel 6. The cooperation between the support frame 5 and the guide wheel 6 ensures that the material remains stable during the conveying process, preventing the material from shifting or deforming. The entire feeding process is smooth and controllable, providing accurate material positioning for the subsequent bending process.

[0036] When the continuous bending mechanism is in operation, the first motor 7 drives the transmission gear 9 to rotate the semi-circular wheel 10. The semi-circular wheel 10 and the guide wheel 6 are set parallel to form a bending reference. The second motor 8 controls the turntable 11 to move, which drives the two sets of symmetrically arranged bending frames 12 to operate. When the material reaches the designated position, the bending frames 12 apply pressure to both ends of the material respectively. The bending is completed in conjunction with the indirect pressing and guiding effect of the semi-circular wheel 10. This bidirectional bending method ensures the continuity and accuracy of the crease.

[0037] When the adjustment mechanism needs support, the adjustment support 13 is movably installed on the top of the top plate 1. The locking tube 14 and the locking rod 15 form a basic support structure. The locking rod 15 passes through different adjustment holes 23 and extends into the locking tube 14 to fix the adjustment support 13 in different positions. The user operates the longitudinal sleeve 17 to slide longitudinally, causing the toothed plate 201 to drive the rotating toothed sleeve 16 to rotate, causing the screw frame 18 to extend into or away from the slot 19, thereby fixing or removing the locking rod 15, and thus fixing and adjusting the position of the adjustment support 13.
