[0028] Specifically, the mounting frame 4 forms a sliding structure with the bending knife 506 through the mounting groove 501 , and the outer wall of the bending knife 506 fits with the inner wall of the mounting groove 501 .

[0029] Through the above technical solution, the connection effect between the mounting frame 4 and the mounting groove 501 and the bending knife 506 is strengthened, so that the bending knife 506 can be well slidably installed in the mounting groove 501 of the mounting frame 4.

[0030] Specifically, the mounting frame 4 forms an elastic structure through the spring 504 and the limiting block 503 , and one end of the limiting block 503 extends into the sliding groove 502 to be connected with the spring 504 .

[0031] Through the above technical solution, there are multiple springs 504, and the multiple springs 504 are equidistantly arranged on the limit block 503. The limit block 503 can press the bending knife 506 tightly through the elastic force of the spring 504, so that the bending knife 506 is not easy to loosen.

[0032] Specifically, the shape and size of the limiting block 503 match the shape and size of the limiting groove 507, and one end of the limiting block 503 extends into the limiting groove 507 for connection.

[0033] Through the above technical solution, the connection effect between the limiting block 503 and the limiting groove 507 is strengthened, so that the limiting block 503 can be well extended into the limiting groove 507 for engagement.

[0035] Through the above technical scheme, the connection effect between the fixing plate 601 and the nut 602 and the screw 603 is strengthened. A turning handle is provided at one end of the screw 603 to facilitate the rotation of the screw 603. A bearing is provided at the other end of the screw 603. The bearing is fixed in the positioning block 604. The thread on the screw 603 matches the thread in the nut 602, so that the screw 603 can rotate well in the nut 602.

[0036] Specifically, the workbench 1 forms a sliding structure with the long groove 606 and the slider 605 , and the outer wall of the slider 605 fits with the inner wall of the long groove 606 .

[0037] Through the above technical solution, when the positioning block 604 moves, it drives the sliding block 605 to slide in the long groove 606 more stably.

[0038] When in use, first connect the device to an external power supply, the external power supply supplies power to the device, the operator aligns the bending mold 8 with the place where the cardboard needs to be bent and places it on the workbench 1, the operator rotates the screw 603 to move the positioning block 604, the positioning block 604 drives the slider 605 to move in the long groove 606, and the outer wall of the positioning block 604 stops after contacting the cardboard. The operator sees the tightness of the cardboard sliding into the workbench 1 as needed, and rotates the screw 603 to adjust as needed. After adjusting the left and front positioning blocks 604, the operator can quickly position and place the cardboard when placing the cardboard, which speeds up the work efficiency. When bending the cardboard, the hydraulic cylinder 3 is started to drive the bending knife 506 to move downward to bend the cardboard. After the bending is completed, the hydraulic cylinder 3 is started to drive the bending knife 506 to move upward and reset. The operator can take the bent cardboard away and bend the lower wheel. When the bending knife 506 is damaged and needs to be replaced, the handle 505 is pulled, and the handle 505 drives the limit The block 503 moves, and the limit block 503 moves from the limit groove 507 of the bending knife 506 back into the slide groove 502, releasing the fixation of the bending knife 506. The operator can pull the bending knife 506 out of the installation groove 501 of the mounting frame 4 to replace it. During installation, the operator pulls the handle 505, and the handle 505 drives the limit block 503 to move back into the slide groove 502. The movement of the limit block 503 drives the spring 504 to contract, and the operator slides the bending knife 506 to the mounting frame 4. After the installation in the slot 501, the handle 505 is released, and the spring 504 rebounds to drive the limit block 503 to move, and the limit block 503 moves to the limit slot 507 of the bending knife 506 to engage, and the limit block 503 uses the elastic force of the spring 504 to press and fix the bending knife 506, completing the installation of the bending knife 506. The installation and disassembly are convenient, the operation is simple, and people's needs are met. This completes all the work. The content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.
