Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1, as Figures 1-2As shown, this utility model provides a technical solution: a bending machine, including a bending fixing frame 1, a processing platform 2, and a bending base 3. The processing platform 2 is installed on the inner wall of the bending fixing frame 1, and the bending base 3 is provided at the top of the processing platform 2. A hydraulic cylinder 5 is provided at the top of the bending fixing frame 1, and a connecting frame 6 is installed at the output end of the hydraulic cylinder 5. A bending block 7 is provided inside the connecting frame 6. Quick installation mechanisms for fixing the bending block 7 and the bending base 3 are provided on both sides of the connecting frame 6 and the processing platform 2, respectively. The quick installation mechanisms include grooves 4 on the outer walls of both the bending block 7 and the bending base 3. Both the side walls of the 6 and the processing platform 2 are provided with cross grooves 12, and a pull rod 13 is provided inside the cross groove 12, which penetrates the groove 4. A piston block 14 adapted to the cross groove 12 is installed on the outer wall of the pull rod 13. A spring 15 is sleeved on the outer wall of the pull rod 13, and the two sides of the spring 15 are respectively connected to the side walls of the cross groove 12 and the piston block 14. By pulling the pull rod 13, the piston block 14 is driven to squeeze the spring 15, thereby separating the pull rod 13 from the groove 4. Then the bending block 7 is removed from the connecting frame 6. This structure facilitates the installation and removal of bending blocks 7 and bending bases 3 of different shapes, meeting the diversified market demands.

[0020] Example 2, as Figures 1-4 As shown, this utility model provides a technical solution: a bending machine, including a processing platform 2 with an internal movable groove 8, and a limit block 9 is provided at the bottom of the movable groove 8 via a slide rail. The movable groove 8 is provided with a shifting mechanism for adjusting the positioning distance. The shifting mechanism includes a motor 10 and a lead screw 11. The rear wall of the bending fixing frame 1 is provided with the motor 10, and the output end of the motor 10 is connected to the lead screw 11 that passes through the limit block 9 via a coupling. The outer wall of the lead screw 11 meshes with the inner wall of the limit block 9. By starting the motor 10, the lead screw 11 is driven to rotate, thereby the lead screw 11 drives the limit block 9 to move within the movable groove 8, and thus the positioning distance of the limit block 9 is adjusted.

[0021] Working principle: First, connect the external power supply. The operator can place the metal material on the processing platform 2 and move it to the position of the limiting block 9. Then, start the hydraulic cylinder 5 to push the connecting frame 6 down. The connecting frame 6 drives the bending block 7 to press the metal material into contact with the bending base 3. Then, the bending is completed by the specific shape of the bending base 3 and the bending block 7. When different bending shapes are required, the positions of the bending block 7 and the bending base 3 can be replaced. The operator pulls the pull rod 13 to drive the piston block 14 to squeeze the spring 15, so that the pull rod 13 separates from the groove 4. Then, the bending block 7 is removed from the connecting frame 6. This structure facilitates the installation and removal of bending blocks 7 and bending base 3 of different shapes to meet diversified market demands. When it is necessary to adjust the bending angle, the motor 10 can be started to drive the lead screw 11 to rotate. The lead screw 11 drives the limiting block 9 to move in the movable groove 8, thereby adjusting the positioning distance of the limiting block 9.
