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.

[0035] Reference Figures 1-3This utility model provides an embodiment of a quick-change auxiliary device for a bending machine mold, including a bending machine 1. The bending machine 1 has an opening to facilitate operation of a movable rod 5. A hydraulic rod 2 is installed on the inner wall of the bottom end of the bending machine 1. The hydraulic rod 2 is a device that uses hydraulic oil as a working medium and utilizes liquid pressure energy to transmit power and achieve various mechanical movements. This is prior art and will not be elaborated further. A connecting frame 3 is fixedly connected to the bottom end of the hydraulic rod 2. The connecting frame 3 provides connection and support for a round rod 4. The round rod 4 is fixedly connected to the inner wall of the connecting frame 3, and the inner wall of the round rod 4 is penetrated and slidable. The movable rod 5 is connected to the circular rod 4, which has a corresponding slot to allow the movable rod 5 to move left and right. The outer wall of the circular rod 4 is rotatably connected to the mold plate 8, which has a corresponding slot to allow the mold plate 8 to rotate. The inner wall of the movable rod 5 is provided with a limit mechanism, and the inner wall of the bending machine 1 is provided with an adjustment component. The limit mechanism includes a plug 6, the bottom end of which is elastically connected to the movable rod 5 via a movable spring 7. The plug 6 is slidably connected to the inner wall of the movable rod 5, and the movable rod 5 has a corresponding slot to allow the plug 6 to move vertically.

[0036] Reference Figure 1 , Figure 6 and Figure 7 The adjustment assembly includes a baffle 9, with a trapezoidal block 10 slidably connected to the outer wall of the baffle 9. A triangular block 11 is elastically connected to the inner wall of the top of the trapezoidal block 10 via a moving spring 12. The baffle 9 passes through and is slidably connected to the inner wall of the bending machine 1. The bending machine 1 has a slot corresponding to the baffle 9, allowing the baffle 9 to move back and forth. The triangular block 11 has an inclined surface. The trapezoidal block 10 passes through and is slidably connected to the inner wall of the bending machine 1. The bending machine 1 has a slot corresponding to the trapezoidal block 10, allowing the trapezoidal block 10 to move left and right. The triangular block 11 is slidably connected to the inner wall of the trapezoidal block 10. The trapezoidal block 10 has a slot corresponding to the triangular block 11, allowing the triangular block 11 to move vertically. The triangular block 11 is inserted into the outer wall of the bending machine 1. The bending machine 1 has multiple sets of slots corresponding to the triangular block 11. When the slots press the inclined surface of the triangular block 11, the triangular block 11 moves downward. The top inner wall of the trapezoidal block 10 is fixedly connected to one end of the moving spring 12, and the other end of the moving spring 12 is fixedly connected to the bottom end of the triangular block 11. When the triangular block 11 moves downward, the moving spring 12 is compressed. When resetting, the elastic force of the moving spring 12 is used to reset the triangular block 11.

[0037] Reference Figures 3-5The bottom end of the insert block 6 is fixedly connected to one end of the movable spring 7, and the other end of the movable spring 7 is fixedly connected to the inner wall of the top of the movable rod 5. When the insert block 6 moves downward, the movable spring 7 is compressed. When resetting, the elastic force of the movable spring 7 is used to reset the insert block 6. The insert block 6 is inserted into the inner wall of the connecting frame 3. The connecting frame 3 has a slot corresponding to the insert block 6. The insert block 6 is initially inserted into the slot. The movable rod 5 is inserted into the left side wall of the mold plate 8. A rectangular block is provided on the movable rod 5. A slot corresponding to the rectangular block is provided on the mold plate 8. The movable rod 5 is initially inserted into the slot.

[0038] Working principle: When it is necessary to change the bending die head, move the insert block 6 downwards. The insert block 6 will compress the movable spring 7. When the insert block 6 separates from the slot on the connecting frame 3, move the insert block 6 to the left. The insert block 6 will move the movable rod 5 to the left. When the rectangular block on the movable rod 5 separates from the slot on the die plate 8, release the insert block 6. The elastic force of the movable spring 7 will cause the insert block 6 to return to its original position. At this time, rotate the die plate 8 to select the die head to be used. When the change is completed, move the insert block 6 downwards. When the insert block 6 no longer blocks the connecting frame 3, move the insert block 6 to the right. The insert block 6 will move the movable rod 5 to the right. When the rectangular block on the movable rod 5 is inserted into the slot on the die plate 8, the insert block 6 coincides with the slot on the connecting frame 3. Release the insert block 6 to allow it to be inserted into the slot on the connecting frame 3, thus completing the limiting of the die plate 8. If the die head needs to be changed again, simply repeat the above operation steps.

[0039] When the position of the baffle 9 needs to be adjusted, move the trapezoidal block 10 to the left. The trapezoidal block 10 will move the triangular block 11 to the left. When the slot on the bending machine 1 presses against the triangular block 11, the triangular block 11 moves downward and compresses the moving spring 12. At the same time, the slot on the trapezoidal block 10 will press the baffle 9 backward. When the baffle 9 is adjusted to the desired position, the triangular block 11 coincides with the slot on the bending machine 1. The elastic force of the moving spring 12 will cause the triangular block 11 to be inserted into the slot of the bending machine 1, completing the adjustment. To limit the position of baffle 9, when the position of baffle 9 needs to be adjusted further, move the triangular block 11 downwards. When the triangular block 11 separates from the slot on the bending machine 1, move the trapezoidal block 10 and the triangular block 11 to the right. The slot on the trapezoidal block 10 will squeeze the baffle 9 forward. When the baffle 9 is adjusted to the desired position, release the triangular block 11 and let the triangular block 11 insert into the slot of the bending machine 1 to complete the limitation of baffle 9. If the position of baffle 9 needs to be adjusted again, simply repeat the above operation steps.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
