Description

Technical Field

[0001] The utility model relates to the technical field of bending equipment, and specifically provides a disassembly and assembly system for the folding edge knife and auxiliary knife of a bending center. Background Art

[0002] In the prior art, the bending area of a bending center mainly includes a slide plate, an upper pressing knife, a lower pressing die, an upper folding knife, a lower folding knife, a moving tool holder, etc. When bending, a sheet is placed between the upper pressing knife and the lower pressing die, and then the upper folding knife and the lower folding knife bend the sheet.

[0003] Generally, the upper folding knife and the lower folding knife are both in one piece, and the common lengths are 1.5 meters, 2 meters, and 2.5 meters. When bending, only one side of the workpiece can be bent in one piece, but in actual work, it often happens that only a small section is bent on one side (the folding lines are not on a straight line). At this time, this kind of folding knife cannot meet the use requirements.

[0004] Secondly, most of the auxiliary knives on the market are manually assembled according to the length of the small folding edge at present, which is time-consuming and has low efficiency. Summary of the Invention

Detailed implementation mode

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not intended to limit the present utility model.

[0025] In the present utility model, unless otherwise stated, the orientation words such as "upper, lower, left, right" generally refer to the upper, lower, left, and right shown in the reference drawings; "inside and outside" refer to the inside and outside relative to the contour of each component itself.

[0026] The following gives a preferred embodiment:

[0027] As Figures 1 - 3 shown, a folding center hemming knife auxiliary knife disassembly and assembly system in this embodiment includes 3 auxiliary knife units 4. A baffle plate 3 is provided on the front side of each auxiliary knife unit 4, and a connection port 21 is provided on the baffle plate 3. A hook 18 is provided on the other side of the baffle plate 3, and the 3 auxiliary knife units 4 are connected together through their respective hooks 18 and the connection ports 21 of the baffle plates of other auxiliary knife units 4;

[0028] A slide block 2 is fixedly connected to the bottom of each auxiliary knife unit 4, and the slide block 2 is slidably connected to the linear guide rail 1.

[0029] The auxiliary knife unit 4 is fixed to the slide block 2 by screws 11. The auxiliary knife unit 4 includes a tool holder 7 and an auxiliary knife 8. The tool holder 7 and the auxiliary knife 8 are connected together by a strong magnet 13, so that the auxiliary knife 8 is in an initial state above the cavity of the tool holder 7, and when the auxiliary knife 8 is stressed, there is space for downward movement.

[0030] A spring 20 is further provided between the inner wall of the tool holder 7 and the auxiliary knife 8. The spring 20 ensures the initial position of the auxiliary knife 8 on the left side of the cavity of the tool holder 7. When the auxiliary knife is stressed, there is space for rightward movement.

[0031] The auxiliary knife 8 includes an inclined surface lifting mechanism. The inclined surface lifting mechanism includes a top rod 10, a top block 9, a micro bearing 14, a connecting shaft 15, a guide shaft 16, an upper spring 19 and a small pressing plate 5. A top rod 10 is provided on the outer side of the auxiliary knife 8, and a top block 9 is provided on the inner side of the auxiliary knife 8;

[0032] A small pressure plate 5 is fixed on the upper side wall of the auxiliary knife 8 through a mounting screw 17. The small pressure plate 5 is connected with an upper spring 19. The upper spring 19 is connected with a guide shaft 16. The guide shaft 16 is connected with a connecting shaft 15. The connecting shaft 15 is connected with a miniature bearing 14. The miniature bearing 14 contacts the top block 9. Among them, the hook 18 is fixedly connected with the guide shaft 16.

[0033] A reset mechanism is arranged on the auxiliary knife 8 on the side opposite to the ejector rod 11. The reset mechanism includes a large pressure plate 6 and a lower spring 12. The large pressure plate 6 is fixed on the outer wall of the auxiliary knife 8. The inside of the large pressure plate 6 is connected with the lower spring 19. The lower spring 19 contacts the top block 9.

[0034] When the folding edge knife auxiliary knife disassembly and assembly system of the utility model is in use, the air cylinder drives the ejector rod 10. The ejector rod 10 pushes the top block 9 to move forward. While the top block 9 moves forward, the guide shaft 16 moves upward accordingly. The hook 18 on the guide shaft 16 also rises. After the air cylinder rod retracts, the lower spring 12 will push the top block 9 to the right for reset.

[0035] Then under the action of the upper spring 19, the guide shaft 16 moves downward, and the hook 18 also moves downward accordingly. The miniature bearing 14 below the guide shaft 16 always abuts against the top block 9.

[0036] In this embodiment, there are 3 auxiliary knife units 4, namely auxiliary knife unit A, auxiliary knife unit B, and auxiliary knife unit C. The auxiliary knife unit A, auxiliary knife unit B, and auxiliary knife unit C are respectively installed on 3 sliders 2. The 3 sliders 2 can move left and right on the linear guide rail 1. Driven by the driving mechanism, it pulls the auxiliary knife unit A to move left and right.

[0037] If you want to realize the connection between the auxiliary knife unit A and the auxiliary knife unit B, the driving mechanism drives the auxiliary knife unit A to collide with the auxiliary knife unit B. When the baffle 3 of the auxiliary knife unit A contacts the hook 18 of the auxiliary knife unit B, the hook 18 will be pushed up. When the auxiliary knife unit A and the auxiliary knife unit B are in full contact, the hook 18 of the auxiliary knife unit B will be pressed down under the action of the upper spring 19, so as to be stuck on the connection port 21 of the baffle 3 of the auxiliary knife unit A, realizing the splicing of the auxiliary knife unit A and the auxiliary knife unit B.

[0038] When you want to separate the auxiliary knife unit A from the auxiliary knife unit B, the auxiliary knife unit A drives the auxiliary knife unit B to the ejector rod mechanism, and then the air cylinder rod pushes the ejector rod 10 of the auxiliary knife unit B to realize the rising of the hook 18. At this time, the driving mechanism can drive the auxiliary knife unit A to separate from the auxiliary knife unit B.

[0039] The above-described embodiments are only one of the more preferred specific implementation manners of the utility model. The general changes and substitutions made by those skilled in the art within the scope of the technical solution of the utility model should be included in the protection scope of the utility model.
