Technical Field
[0001] This utility model relates to the field of steel plate pre-bending processing technology, and in particular to a steel plate pre-bending device for orthopedic clinical surgery. Background Technology
[0002] In orthopedic surgery, plate pre-bending is often used to correct fractures or bone displacement. Traditional plate pre-bending devices usually require applying external force to the metal plate to bend it to ensure that it can match the patient's bone shape. Most existing plate pre-bending devices use horizontal clamping to fix the plate and ensure that the plate is stable and does not move during the bending process.
[0003] Existing steel plate pre-bending devices typically only fix one side of the steel plate using horizontal clamping components. While this can temporarily prevent significant displacement of the steel plate during bending, it does not adequately consider the overall stability of the steel plate. For example, the other side of the steel plate does not provide sufficient vertical compressive force, which may cause displacement or instability during bending when an external force is applied. Therefore, those skilled in the art have provided a steel plate pre-bending device for orthopedic clinical surgery to solve the problems mentioned in the background art. Utility Model Content

[0033] Reference Figure 1-3 and Figure 5This utility model provides a specific embodiment: a pre-bending device for orthopedic clinical surgical plates, comprising a fixed platform 1 and a movable frame 12. A platform 2 is fixedly connected to one side of the upper end of the fixed platform 1. A fixed frame 3 is fixedly connected to the rear of the upper end of the platform 2.

A movable slider 22 is threaded onto the outer wall of the movable screw 21. A clamping plate 31 is fixedly connected to the upper end of the movable slider 22. A third motor 23 is fixedly provided at the front end of the platform 2. The third motor 23 is started to rotate the moving screw 21, which in turn moves the clamping plate 31 via the moving slider 22. This, in turn, works with the fixed frame 3 to horizontally clamp the steel plate. The inner walls of both sides of the moving groove 20 are provided with second limiting grooves 24. The two second limiting grooves 24 are each slidably provided with second limiting blocks 25. The two second limiting blocks 25 are fixedly connected to the moving slider 22.

By providing the position adjustment assembly 13, the position of the pressure plate 30 can be flexibly adjusted according to the specifications of the steel plate and the required bending position, thus enabling the device to adapt to the needs of various specifications of steel plates. This greatly improves the versatility and adaptability of the device. The inner walls of the front and rear ends of the adjustment groove 15 are provided with first limiting grooves 17. The interior of the two first limiting grooves 17 is slidably provided with first limiting blocks 18. The two first limiting blocks 18 are fixedly connected to the adjustment slider 16. The output end of the second motor 19 passes through the fixed platform 1 and is fixedly connected to the adjustment screw 14. By providing the first limiting grooves 17 and the first limiting blocks 18, the adjustment slider 16 can move stably and effectively. Thus, the movement of the adjustment slider 16 can be controlled by starting the second motor 19.
[0036] Working Principle: In use, the steel plate to be processed is first placed on the platform 2. The third motor 23 is activated, causing the moving lead screw 21 to rotate. This, along with the moving slider 22, moves the clamping plate 31, which, in conjunction with the fixing frame 3, horizontally clamps the steel plate. Simultaneously, the first motor 11 is activated, causing the first threaded rod 5 to rotate. This, along with the first threaded sleeve 6, moves the pressure plate 7 downward, vertically clamping the steel plate and providing additional support. This prevents displacement or instability during bending when an external force is applied, enhancing the fixing effect and ensuring that the shape of the steel plate does not change unnecessarily during pre-bending, effectively improving... The stability of the fixed steel plate ensures the reliability of the pre-bending process. In addition, the device is equipped with a position adjustment component 13, which allows the position of the pressure plate 30 to be flexibly adjusted according to the specifications of the steel plate and the required bending position. That is, by starting the second motor 19, the adjusting screw 14 is rotated, and the moving frame 12 can be moved laterally through the provided adjusting slider 16, thereby changing and adjusting the position of the pressure plate 30. This allows the device to adapt to the needs of various specifications of steel plates, greatly improving the versatility and adaptability of the device. Finally, by starting the fourth motor 28, the second threaded rod 26 is rotated, and the pressure plate 30 can be controlled to move longitudinally and apply pressure through the provided second threaded sleeve 27.
