Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figure 1-Figure 4 A wrench forming machine shown in the figure comprises a fixed platform 1, a wire drum roll 2 is provided on the top of the fixed platform 1, a straightening device 3 for adjusting the curled wire into a straight line is provided on one side of the wire drum roll 2, a grinding wheel mechanism 4 for hexagonal plasticity is provided on one side of the straightening device 3, a guide wheel 5 is provided on the other side of the grinding wheel mechanism 4, a bending assembly 6 is provided on the other side of the guide wheel 5, a breaking device 7 is provided on one side of the bending assembly 6, and a pushing assembly 8 for pushing the processed workpiece out of the bending assembly 6 is provided on the side of the bending assembly 6 close to the guide wheel 5.

[0020] Furthermore, the bending component 6 includes a motor 601, a motor bracket 602 is provided on the outside of the motor 601, the motor bracket 602 is fixedly connected to the bottom of the fixed platform 1, the output shaft of the motor 601 is fixedly connected to the rotating outer ring 603, a fixed inner ring 604 is provided on the inside of the rotating outer ring 603, a pushing component 8 is provided inside the fixed inner ring 604, and a cylindrical block 606 is provided on the top of the rotating outer ring 603. The motor in the bending component is used as a power source to provide a stable and controllable rotational force for the entire bending process, and the shape of the cylindrical block enables it to effectively reduce the extrusion and friction of the workpiece during the bending process, thereby reducing the risk of indentation on the inner side of the workpiece.

[0021] Furthermore, a sliding groove is opened on one side of the rotating outer ring 603, and a positioning rod 605 is arranged inside the sliding groove. One end of the positioning rod 605 extends to the inside through the outer wall of the fixed platform 1 and is fixedly connected to the fixed inner ring 604. By opening a sliding groove on one side of the rotating outer ring and arranging a positioning rod fixedly connected to the fixed inner ring inside, the moving path of the rotating outer ring during the bending process is ensured, and at the same time, the fixed inner ring is ensured to be stable and motionless, thereby improving the processing accuracy of the workpiece.

[0022] Furthermore, a group of mutually parallel guide blocks 607 are provided on the top of the fixed inner ring 604, and a pushing assembly 8 is provided on the inner side of the guide block 607. The introduction of the guide block is precisely to stabilize the moving path of the workpiece during the processing and ensure the linear motion of the workpiece during the bending process, which not only improves the processing accuracy of the workpiece, but also greatly reduces the generation of defective products, thereby improving production efficiency.

[0023] Furthermore, the pushing component 8 includes a telescopic rod 801, a limit groove is provided at one end of the telescopic rod 801, a spring 802 is provided inside the limit groove, and one end of the spring 802 is tightly pressed against the limit rod 803. Through the flexible extension and retraction of the telescopic rod, workpieces of different lengths and positions can be coped with, thereby improving the versatility and adaptability of the equipment; secondly, the ingenious combination of the limit groove, the spring and the limit rod provides a stable and uniform driving force for the workpiece, ensuring that the processing process can be flexibly rotated within a certain range, thereby better adapting to various changes in the processing process.

[0024] Furthermore, one end of the limit rod 803 is rotatably connected to the limit groove, and a downward pressure block 804 is provided on one side of the limit rod 803. The bottom surface of the downward pressure block 804 tightly presses one end of the spring 802, and one end of the limit rod is rotatably connected to the limit groove, so that the limit rod can flexibly rotate within a certain range, thereby better adapting to various changes in the processing process.

[0025] In this solution, the workflow is as follows: first, the wire drum roll is the starting point of the entire production line, and the wire drum roll is responsible for providing the original wire material.

[0026] When the steel wire is released from the wire drum, it will first pass through the straightening device. The function of the straightening device is to adjust the originally curled or bent steel wire into a straight state, providing an accurate material basis for subsequent processing.

[0027] Next, the straightened steel wire will enter the grinding wheel mechanism, which is a key link in the formation of the wrench. It is responsible for the hexagonal plastic treatment of the steel wire so that the steel wire gradually forms the basic shape of the wrench.

[0028] After the plastic treatment of the grinding wheel mechanism, the steel wire will pass through the guide wheel and be accurately guided to the next processing link - the bending component. The bending component is the core part of the wrench forming machine, which is driven by a motor. A bracket is provided on the outside of the motor, which is firmly connected to the bottom of the fixed platform, providing powerful power for the entire bending process. The output shaft of the motor is connected to the rotating outer ring. When the motor is started, the rotating outer ring will start to rotate and work with the fixed inner ring.

[0029] A pushing assembly is installed inside the bending assembly. The function of the pushing assembly is to smoothly push the processed workpiece out of the bending assembly after the wrench is formed, so as to carry out the next step of processing or collection.
