However, for the bending operation of some large sheets, when the flipping bracket assists the sheet to flip, the stability is not good enough, it is easy to shake. Especially during the flipping process, it is easy to deviate, resulting in a change in the flipping angle, which affects the bending effect. Therefore, the utility model provides an auxiliary bending mechanism for a bending machine. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution for an auxiliary bending mechanism for a bending machine: an auxiliary bending mechanism for a bending machine, including a bending machine 1 and a front vertical plate 4 provided at the lower end of the front side of the bending machine 1. A feeding rack 2 fixed to the front vertical plate 4 is provided at the lower end of the front side of the bending machine 1. A bending auxiliary component 3 for assisting in bending the material is further provided on the front side of the front vertical plate 4 inside the feeding rack 2. The bearing rack 31 on the bending auxiliary component 3 is of a rectangular structure, and lifting legs 30 are provided at the four corners of the bottom of the bearing rack 31. One side of the bearing rack 31 is fixed to the front side of the front vertical plate 4 by bolts. The overall height of the bending auxiliary component 3 can be adjusted through the lifting legs 30 to facilitate adapting to the bending requirements of the bending machine. After the bending auxiliary component 3 is adjusted, one side of it is fixed to the front vertical plate 4 by bolts to improve the stability of the bending auxiliary component 3 during operation;

[0026] Such as Figure 5 and 6As shown in the figure, the bending auxiliary component 3 includes a carrier 31 fixed to the front vertical plate 4 and a plurality of bearing seats 40 evenly distributed on one side of the upper end of the carrier 31 close to the front vertical plate 4. A rotating rod 39 is connected to the plurality of bearing seats 40 in common. The rotating rod 39 is rotatably connected to the bearing seats 40. A plurality of connecting seats 37 are fixed near the bearing seats 40 on the rotating rod 39. At the top of one end of each connecting seat 37, a bending push plate 38 is fixed. The bending push plate 38 is formed by welding an arc-shaped plate and a rectangular plate. The rectangular plate is fixed to the upper surface of one end of the connecting seat 37 through the arc-shaped plate. By designing a plurality of bending push plates 38, when the material is bent, the plurality of bending push plates 38 can follow the material to flip and move synchronously. Thus, the bending machine can rotate by 0-90 degrees, and the bending of small workpieces does not require rear follow-up assistance, thereby improving the bending efficiency of the material.

[0027] As Figure 6 and 7 shown in the figure, the bending auxiliary component 3 further includes a reducer 33 and a driving motor 32 installed in the middle of an inner side wall of the carrier 31 close to the front vertical plate 4. The output end of the driving motor 32 is connected to the input end of the reducer 33. The output end of the reducer 33 is fixedly connected with a first connecting plate 34. The other end of the first connecting plate 34 is movably connected with a second connecting plate 35. The other end of the second connecting plate 35 is connected with a connecting rod 36. By using the driving motor 32 to work, the first connecting plate 34 is driven to rotate. Thus, with the cooperation of the second connecting plate 35, the connecting rod 36 can be pushed to rise, and then one end of the connecting seat 37 can make an arc-shaped movement around the other end, so as to realize the follow-up and auxiliary bending operation of the bending push plate 38 on the material.

[0028] As Figure 5 and 6 shown in the figure, the bottom of one end of the connecting seat 37 is fixedly connected with the rotating rod 39, and the bottom of the other end of the connecting seat 37 is fixed on the connecting rod 36, which is convenient for using the connecting rod 36 to push one end of the connecting seat 37 to rise. The other end uses the rotational connection between the rotating rod 39 and the bearing seat 40 to limit the other end of the connecting seat 37, so that when the connecting seat 37 is pushed and lifted by the connecting rod 36, the lifted end of the connecting seat 37 makes a circular movement around the other end.

[0029] As Figure 5As shown in the figure, a guiding mechanism for guiding the flipping of the bending push plate 38 is further provided on the carrier 31. The guiding mechanism includes a guiding rod 41 fixed to one end of the rotating rod 39, and a guiding arc plate 42 installed near the guiding rod 41 at the upper end of the carrier 31. An arc-shaped guiding groove 43 is formed on the surface of the guiding arc plate 42. A guiding slider is vertically connected to the guiding rod 41 corresponding to the guiding groove 43, and the guiding slider is located in the guiding groove 43 and slides therein. The guiding rod 41 is slidably connected to the guiding arc plate 42 through the guiding slider. When one end of the connecting seat 37 is lifted, the other end will drive the rotating rod 39 to rotate in the bearing seat 40. When the rotating rod 39 rotates, it will drive the guiding rod 41 to rotate. One end of the guiding rod 41 is guided by the guiding slider sliding in the guiding groove 43. Thus, when the connecting seat 37 flips, it can always be in a fixed flipping trajectory, and the stability of the bending push plate 38 during flipping can be further improved.

[0030] The working principle of the present utility model is as follows: During operation, the material is conveyed to the bending machine through the feeding rack 2. When the material reaches the material stop finger of the bending machine, the bending machine operates to bend the material. At this time, the bending machine control device will control the driving motor 32 to operate. The driving motor 32 will drive the first connecting plate 34 to rotate through the reducer 33. The rotation of the first connecting plate 34 will drive the second connecting plate 35 to push the connecting rod 36 upward. While the connecting rod 36 rises, it will drive one end of a plurality of connecting seats 37 thereon to rise. Further, when one end of the connecting seat 37 rises, it will perform an arc-shaped movement (i.e., a flipping movement) around the other end. At this time, the bending push plate 38 will flip from below the feeding rack 2 to above it. During the flipping process, the bending push plate 38 cooperates with the bent material to ensure the bending efficiency of the material.

[0031] During the process of the connecting seat 37 driving the bending push plate 38 to flip, the other end of the connecting seat 37 will drive the rotating rod 39 to rotate in the bearing seat 40. Moreover, one end of the rotating rod 39 is guided and limited by the guiding mechanism, which can ensure that when the connecting seat 37 flips, it is always in a fixed flipping trajectory, and the stability of the bending push plate 38 during flipping can be further improved.

[0032] After the bending is completed, the driving motor 32 rotates in the reverse direction, so that the first connecting plate 34 drives the second connecting plate 35 to reset, and then drives the connecting seat 37 to reset through the connecting rod 36. After the reset is completed, the bending push plate 38 resets below the feeding rack 2 (in a horizontal state) to facilitate the re-conveying and bending operation of the material.

[0033] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
