[0002] As an actuator for a bending machine to achieve a bending effect, the bending head is generally of an integral structure. After the bending head makes hard contact with tools or other objects due to misoperation and its local part deforms, the entire bending head needs to be replaced. And because the whole is replaced, after installing a new bending head again, it is necessary to install and calibrate the bending head again to ensure the bending effect. The replacement cost is high and it takes a long time. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a bending machine actuator to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A bending machine actuator includes a mounting plate. A notch is opened inside the mounting plate.

One end of the mounting plate is fixedly connected with a limiting plate for limiting the top of the spliced bending heads. Adjacent spliced bending heads are connected by a splicing mechanism.

[0005] The splicing mechanism is used to align and splice adjacent spliced bending heads.

[0006] A through hole for the mounting bolt to penetrate is opened inside the upper half of the spliced bending head. The mounting bolt penetrates through the notch and the through hole and is threadedly connected with the nut. The nut in a tightened state cooperates with the end of the mounting bolt to press the mounting plate and the spliced bending head.

One end of the connecting groove is open, and the other end is closed. A cross plate is slidably installed on the inner wall of the connecting groove. A pressing plate is integrally formed on the side of the cross plate aligned with the open end of the connecting groove. A receiving groove for receiving the pressing plate is opened on one side of the through hole.

[0008] As a further scheme of the utility model: The splicing mechanism further includes a vertical plate fixedly connected to the back end of the cross plate. One end of the vertical plate is fixedly connected with a slider. A sliding groove is opened at the other end of the vertical plate. The cross sections of the vertical plate and the slider are both in a "convex" shape structure, and the inner wall of the vertical plate coincides with the outer wall of the slider.

[0009] As a further solution of the present utility model: a counterbore is provided inside the pressing plate, and a threaded hole is provided at a position inside the through hole aligned with the counterbore, and a pressing bolt passes through the counterbore and is threadedly connected to the threaded hole.

[0010] As a further solution of the present utility model: the cross section of the horizontal plate and the vertical plate is a "T" - shaped structure rotated by ninety degrees, which is used to prevent the vertical plate on the adjacent splicing elbow and the slider from moving up and down during splicing and contacting and interfering with the splicing elbow.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] 1. By setting the splicing elbow and the splicing mechanism, when local deformation occurs, only the corresponding splicing elbow needs to be replaced, without the need for overall replacement, and the remaining undeformed elbows play a calibration effect, so the time spent during the replacement process is relatively short.

[0018] 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 of 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.

[0019] Please refer to Figures 1 to 4, in the embodiment of the present utility model, an actuating mechanism of a bending machine includes a mounting plate 1. A notch 2 is formed inside the mounting plate 1. The mounting plate 1 is detachably connected with a bending tool through mounting bolts and nuts. The bending tool is composed of a plurality of spliced bending heads 4 spliced together. One end of the mounting plate 1 is fixedly connected with a limiting plate 3 for limiting the top of the spliced bending heads 4. Adjacent spliced bending heads 4 are connected by a splicing mechanism; the splicing mechanism is used to align and splice adjacent spliced bending heads 4; a through hole 5 for the mounting bolt to pass through is formed inside the upper half of the spliced bending head 4. The mounting bolt passes through the notch 2 and the through hole 5 and then is threadedly connected with the nut. The nut in the tightened state cooperates with the end of the mounting bolt to press the mounting plate 1 and the spliced bending head 4.

[0020] In this embodiment: when installing the frontmost or the rearmost spliced bending head 4 on the mounting plate 1, align the top of the spliced bending head 4 with the bottom end of the limiting plate 3 and closely fit them. Then use the mounting bolt to pass through the through hole 5 and the notch 2, and then tighten the nut to complete the installation of one spliced bending head 4. Then sequentially install the other spliced bending heads 4 through the splicing mechanism and fix them with the mounting bolts and nuts. The splicing mechanism can prevent the existence of uneven gaps between adjacent splicing pillows and realize the equidistant distribution of a plurality of spliced bending heads 4;

[0021] When tools are placed on the top of the bending groove and the device is accidentally started, when the plurality of spliced bending heads 4 move downward and cause a hard extrusion between a single or multiple spliced bending heads 4 and the tools, resulting in damage to a single or multiple spliced bending heads 4, the corresponding damaged spliced bending heads 4 can be removed through the splicing mechanism and replaced, without replacing the entire bending head.

[0022] Please refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4 , the splicing mechanism includes a connecting groove 12 horizontally formed at the back end of the spliced bending head 4. One end of the connecting groove 12 is open, and the other end is closed. A cross plate 6 is slidably installed on the inner wall of the connecting groove 12. One side of the cross plate 6 aligned with the open end of the connecting groove 12 is integrally formed with a pressing plate 7. A receiving groove for accommodating the pressing plate 7 is formed on one side of the through hole 5. A counterbore is formed inside the pressing plate 7, and a threaded hole 11 is formed at the position where the inside of the through hole 5 is aligned with the counterbore. The pressing bolt passes through the counterbore and is threadedly connected with the threaded hole 11.

[0023] In this embodiment: After the damaged spliced elbow 4 is removed, by loosening the compression bolt until the compression bolt is completely removed. At this time, by pulling the cross plate 6, the cross plate 6 is separated from the connection groove 12, and at the same time the cross plate 6 drives the pressing plate 7 to be separated from the accommodation groove, separating the splicing mechanism from the damaged spliced elbow 4. Then, a new spliced elbow 4 is assembled with the splicing mechanism. Specifically: The sliding end of the cross plate 6 is slidably butted with the connection groove 12 of the spliced elbow 4 until the two are completely coincident. At this time, the pressing plate 7 completely enters the accommodation groove. Then, the compression bolt is threaded through the counterbore and the screw hole 11 until the compression bolt is completely tightened. Finally, the new spliced elbow 4 is butted with the spliced elbow 4 fixed on the mounting plate 1.

[0024] Please refer particularly to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the splicing mechanism further includes a vertical plate 8 fixedly connected to the back end of the cross plate 6. One end of the vertical plate 8 is fixedly connected with a slider 9, and the other end of the vertical plate 8 is provided with a sliding groove 10. The cross sections of the vertical plate 8 and the slider 9 are both in a "convex" shape structure, and the inner wall of the vertical plate 8 coincides with the outer wall of the slider 9.

[0025] In this embodiment: The splicing mechanism at the back end of the new spliced elbow 4 is butted with the splicing mechanism at the back end of the fixed spliced elbow 4, that is: The slider 9 is aligned with the sliding groove 10, and then the splicing mechanism is pushed up to realize the docking of two adjacent splicing mechanisms. Due to the limitation of the slider 9 and the sliding groove 10, the docking of two adjacent spliced elbows 4 is realized until the top of the spliced elbow 4 to be installed is attached to the bottom end of the limiting plate 3. Then, it can be fixed with installation bolts and nuts.

[0026] Please refer particularly to Figure 2 , the cross sections of the cross plate 6 and the vertical plate 8 are in a "T" - shaped structure rotated by ninety degrees, which is used to avoid the up - and - down movement of the vertical plate 8 and the slider 9 on adjacent spliced elbows 4 from contacting and interfering with the spliced elbow 4 during splicing.

[0027] In this embodiment: Since the slider 9 is convex and the lower half of the spliced elbow 4 is in a bent state, if they are not misaligned, the slider 9 will contact and interfere with the bent part of the spliced elbow 4 during the up - and - down movement.

[0028] The above - mentioned is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
