[0003] Chinese Patent Publication (CN202222702396.7) discloses a disassembly-free multi-angle bending machine die and a bending machine. By loosening the upper die fixing bolts of the die mounting seat, rotating the upper die or upper tool of the bending machine die clockwise or counterclockwise by 90° around the rotating connection shaft, and then tightening the upper die fixing bolts on the other side, the working mode with different bending angles can be switched. However, when this application is used, there are still the following technical problems: when this kind of die is bent, the connection shaft of the die is directly stressed, which is easy to cause damage to the connection shaft, affecting the service life of the die, and the angle of the die cannot be adjusted after the connection shaft is damaged;

[0004] To solve the above technical problems, a disassembly-free multi-angle bending machine die is proposed. Content of the Utility Model

[0005] In view of this, the utility model provides a disassembly-free multi-angle bending machine die to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial choice.

[0006] The technical solution of the utility model is realized as follows: a disassembly-free multi-angle bending machine die includes a main body mechanism and an adjustment mechanism;

[0007] The main body mechanism includes a mounting base and an upper die. A placement groove is integrally formed on one side of the mounting base, the upper die is arranged inside the placement groove, and sliding grooves are symmetrically formed inside the mounting base;

[0008] The adjustment mechanism includes a connecting rod and a rotating shaft. The rotating shaft penetrates through the upper die and is rotatably connected to the upper die. One ends of the two connecting rods are fixedly connected to the rotating shaft. A pull rod is fixedly connected to one end of the connecting rod, and an anti-slip sleeve is sleeved on one side of the pull rod.

[0014] Due to the adoption of the above technical solutions in the embodiments of the present utility model, it has the following advantages:

[0015] First, the present utility model drives the upper die to move up and down by setting the pull rod in cooperation with the connecting rod and the rotating shaft. After the upper die is disengaged from the placement groove, the upper die can be rotated in cooperation with the rotating shaft to adjust the use angle of the upper die according to the bending requirements, and after adjustment, the upper die is moved to the placement groove for fixation, so that when the upper die is bent, components such as the rotating shaft are not affected, and the upper die itself bears the force, extending the service life of the upper die and facilitating the adjustment of the use angle of the upper die;

[0016] Second, the present utility model buffers when the upper die is stressed by setting the collar in cooperation with the spring and the shock-absorbing rubber pad, preventing the contact surface between the upper die and the mounting base from being worn, and reducing the influence of vibration on the upper die during the bending process.

Detailed Embodiments

[0025] In the following text, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0026] The following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0027] As Figure 1 shown in FIG. -5, an embodiment of the present utility model provides a non-detachable multi-angle bending machine die, which is composed of a main body mechanism 10 and an adjusting mechanism 20.

[0028] The main body mechanism 10 includes a mounting base 11, an upper die 12, and a connecting plate 14. The connecting plate 14 is symmetrically and fixedly connected to the top of the mounting base 11. Mounting holes 15 are symmetrically formed inside the connecting plate 14. The cooperation of the connecting plate 14 and the mounting holes 15 facilitates the connection and fixation of the mounting base 11 to the bending machine. A placement groove 31 is integrally formed on one side of the mounting base 11 for the upper die 12 to fit with the mounting base 11 through the placement groove 31, preventing the angle deviation of the upper die 12 during the bending process. The upper die 12 is arranged inside the placement groove 31. The upper die 12 is cross-shaped, and each protruding part is integrally formed with a folding knife shape at a different angle. Sliding grooves 13 are symmetrically formed inside the mounting base 11.

[0029] In one embodiment, in order to prevent the contact surface between the upper die 12 and the mounting base 11 from being worn or damaged, shock-absorbing rubber pads 33 are symmetrically and fixedly connected to one side inside the placement groove 31, and a soft pad 32 is fixedly connected to one side inside the placement groove 31.

[0030] In one embodiment, in order to reduce the influence of vibration on the upper die 12 during the bending process, a fixing ring 26 is fixedly connected to one side of the connecting rod 21. A collar 18 is sleeved on one side of the connecting rod 21. The collar 18 is slidably connected to the mounting base 11 through the sliding groove 13. A spring 19 is fixedly connected to one side of the collar 18, and one end of the spring 19 is fixedly connected to the mounting base 11.

[0031] The adjustment mechanism 20 includes a connecting rod 21, a rotating shaft 24, and a pull rod 22. The rotating shaft 24 penetrates through the upper die 12 and is rotatably connected to the upper die 12. One ends of the two connecting rods 21 are both fixedly connected to the rotating shaft 24. One end of the connecting rod 21 is fixedly connected to the pull rod 22. An anti-slip sleeve 23 is sleeved on one side of the pull rod 22. By pulling the pull rod 22, the connecting rod 21 and the rotating shaft 24 are driven to move, and the rotating shaft 24 drives the upper die 12 to move up and down, facilitating the removal of the upper die 12 from the placement groove 31 for angle adjustment. In order to prevent the position deviation of the upper die 12, limiting rings 25 are symmetrically and fixedly connected to one side of the rotating shaft 24.

[0032] In one embodiment, in order to facilitate the fixation of the connecting rod 21 after adjusting the upper die 12 and prevent the upper die 12 from being disengaged from the placement groove 31, a jack 27 is formed on one side of the connecting rod 21. Two fixing plates 16 are symmetrically and fixedly connected to one side of the mounting base 11. A fixing bolt 17 is threadedly connected inside the fixing plate 16, and one side of the fixing bolt 17 penetrates through the jack 27.

[0033] When the utility model works: Connect the mounting seat 11 to the bending machine through the connecting plate 14 and the mounting holes 15. Pull the pull rod 22 to drive the connecting rod 21 and the rotating shaft 24 to move downward. The rotating shaft 24 drives the upper die 12 to be disengaged from the placing groove 31. Rotate the upper die 12, select the corresponding bending edge according to the bending requirement, and after adjustment, pull the pull rod 22 upward to drive the upper die 12 to be clamped into the placing groove 31, so that the upper die 12 contacts the soft pad 32 and the shock-absorbing rubber pad 33. Rotate the fixing bolt 17 to make one end of the fixing bolt 17 pass through the jack 27 and connect with the fixing plate 16 to fix the position of the connecting rod 21 and prevent the upper die 12 from being disengaged from the placing groove 31. The bending machine drives the mounting seat 11 and the upper die 12 to move for bending. After bending, adjust the use angle of the upper die 12 again according to the requirement.

[0034] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
