[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0021] Example

[0022] like Figures 1 to 4As shown, a bending and shaping device for a bone plate of the present invention comprises a base 1, a driving mechanism 9 and a punching head 11. The base 1 is a rectangular structure. A slide groove 15 is provided on the top of the base 1. A plurality of blind holes 16 are evenly provided in the slide groove 15. Two movable blocks 5 are also provided in the slide groove 15. Both sides of the movable blocks 5 are provided with protrusions 17. Both sides of the inner wall of the slide groove 15 are provided with guide grooves matching the protrusions 17. The protrusions 17 on both sides of the movable block 5 are respectively located in the guide grooves. When the movable block 5 moves in the slide groove 15, the protrusions 17 will be able to move in the guide grooves, so that the two movable blocks 5 can move smoothly on the base 1 to adjust the distance between the two movable blocks 5. Positioning rods 2 and support columns 3 are also provided on the tops of the protrusions 17. The positioning rod 2 is vertically connected to the protrusion 17 through a thread. By rotating the positioning rod 2, the positioning rod 2 can move to the blind hole 16 in the same vertical direction as the positioning rod 2. The positioning rod 2 can fix the movable block 5 in the slide groove 15. When it is necessary to adjust the distance between the two movable blocks 5, the positioning rod 2 is rotated so that the positioning rod 2 is moved out of the blind hole 16, and the movable block 5 can move in the slide groove 15. The top of the support column 3 is also provided with a support platform 4, and the top of the support platform 4 is provided with a groove 11. The groove 11 connects the two opposite sides of the support platform 4. When the bone plate is processed, the groove 11 is used to place the bone plate to be processed. Both sides of the support platform 4 are provided with movable rods 14, and the movable rods 14 are connected to the support platform 4 through threads, and one end of the movable rod 14 Located in the groove 11, the movable rod 14 is also provided with a connecting block 13 on the end thereof located in the groove 11, the movable rod 14 can rotate in the connecting block 13, and a clamping plate 12 is also provided on the connecting block 13. Since the movable rod 14 is connected to the support platform 4 through a thread, when the movable rod 14 rotates in the connecting block 13, the movable rod 14 will push the clamping plate 12 to move in the groove 11. The two clamping plates 12 in the groove 11 are used to fix the bone plate to be processed in the groove 11, thereby avoiding the bone plate from displacing itself during processing and affecting the processing accuracy. At the same time, it is suitable for bone plates of different widths and ensures that the bone plate to be processed can be fixed at the central position of the groove 11. An adjustment handle is also provided on the end of the movable rod 14 located on the outer side of the support platform 4 6. The adjusting handle 6 is convenient for the user to rotate the movable rod 14; four support rods 7 are also provided on the top of the base 1, and the support rods 7 are respectively located at the four corners of the base 1. A top plate 8 is provided on the top of the support rod 7, and the four bottom corners of the top 8 are respectively connected to the four support rods 7. The driving mechanism 9 is located at the central position of the top plate 8. The driving mechanism 9 is preferably a hydraulic cylinder, which has stable operation and convenient control. The driving mechanism 9 also includes an output shaft 10, which is vertically inserted on the top plate 8, and the bottom end of the output shaft 10 is connected to the punch head 18, and the axis of the punch head 18 is perpendicular to the line between the two support platforms 4. When the driving mechanism 9 is working, its output shaft 10 will drive the punch head 18 to punch the bone plate fixed on the support platform 4, forcing the bone plate to bend.

[0023] When the present invention is used, the positioning rod 2 on the movable block 5 is loosened so that the movable block 5 can move in the slide groove 15. According to the length of the bone plate to be processed, the distance between the two support platforms 4 is adjusted so that the two ends of the bone plate can be placed in the grooves of the support platforms 4. The movable rod 14 is rotated so that the clamping plate 12 fixes the bone plate in the groove 11. The driving mechanism 9 is turned on, and the output shaft 10 on the driving mechanism 8 drives the punch head 18 to move downward to punch and bend the bone plate fixed on the support platform 4.

[0024] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
