The mounting disk 11 is also provided with a driving unit 5 for driving the threaded driving rod 21 to rotate. The plug-in blocks 24 are arranged in a ring around the threaded driving rod 21 and can slide along the radial direction of the threaded driving rod 21. The mounting disk 11 is also provided with an adjusting unit 3 for driving each plug-in block 24 to move along the radial direction of the threaded driving rod 21 at the same time. A winding column 22 is sleeved on the threaded driving rod 21, and an internal threaded hole matching the threaded driving rod 21 is arranged inside the winding column 22. A plurality of connecting seats 23 are arranged in a ring at one end of the winding column 22 close to the mounting disk 11. A guide rod 28 is connected to the end of the connecting seat 23, and the guide rod 28 passes through the mounting disk 11 and can slide along the axial direction of the threaded drive rod 21. An outer protective rod 25 is slidably installed on each of the connecting seats 23, and an insertion hole 251 for matching the plug-in block 24 is opened at one end of the outer protective rod 25 close to the connecting seat 23, a positioning block 26 is slidably installed in the insertion hole 251, and the positioning block 26 is connected to the inside of the insertion hole 251 through a return spring 27, and positioning grooves 231 matching the positioning block 26 are equidistantly distributed on the connecting seat 23, a clamping block 252 is provided at one end of the outer protective rod 25 away from the connecting seat 23, and a clamping groove 221 matching the clamping block 252 is provided at one end of the winding column 22 away from the mounting disk 11.

[0018] In the embodiment of the present invention, in the initial state, one end of the winding column 22 is in contact with the mounting plate 11, and each outer guard rod 25 is in a state away from the winding column 22 (i.e., the distance between the winding column 22 and the outer guard rod 25 is the largest), and at this time, the plug-in block 24 is plugged into the plug-in hole 251, and the positioning plug-in block 26 is pushed out from the positioning groove 231 through the plug-in block 24, and the reset spring 27 is in a compressed state. When in use, the operator can wind the cold-headed steel wire on the winding column 22, or directly put the whole roll of cold-headed steel wire on the winding column 22. Then start the adjustment unit 3, and the adjustment unit 3 drives each plug-in block 24 to move simultaneously to the side close to the threaded drive rod 21, and the plug-in block 24 can drive the outer guard rod 25 to move synchronously until the clamping block 252 at the end of the outer guard rod 25 is clamped into the clamping groove 221, so that the cold-headed steel wire can be fixed on the winding column 22. At this time, the inner side of the outer guard rod 25 will abut against the cold-headed steel wire, or a certain margin is selected. Then the driving unit 5 is started, and the threaded driving rod 21 is driven to rotate by the driving unit 5. Through the cooperation between the threaded driving rod 21 and the internal threaded sleeve, the threaded driving rod 21 can drive the winding column 22 to move along its axial direction, thereby sending the cold-headed steel wire to be processed into the heat treatment equipment, and in this process, the outer guard rod 25 will be separated from the plug-in block 24. At this time, under the elastic restoring force of the reset spring 27, the positioning plug-in block 26 will be plugged into the positioning groove 231, thereby fixing the position of the outer guard rod 25. During the movement of the winding column 22, the connecting seat 23 will drive the guide rod 28 to move synchronously, thereby playing a guiding role, preventing the winding column 22 from rotating, and at the same time increasing the stability of the winding column 22 during movement.

The mounting plate 11 is provided with a moving unit 4 for driving the sliding sleeve 31 to move along the axial direction of the driving shaft 211. The number of the adjustment columns 32 is the same as the number of the plug-in blocks 24, and each of the adjustment columns 32 is respectively connected to each corresponding plug-in block 24. Two adjustment connecting rods 33 are rotatably installed on one side of the adjustment column 32 close to the sliding sleeve 31, and the end of the adjustment connecting rod 33 away from the adjustment column 32 is rotatably installed on the side wall of the sliding sleeve 31.

[0022] like Figure 2 and Figure 7 As shown, as a preferred embodiment of the present invention, the moving unit 4 includes a telescopic member 41 installed on the mounting plate 11 , the telescopic end of the telescopic member 41 is connected to a connecting ring 42 , and the connecting ring 42 is connected to the side wall of the sliding sleeve 31 .

[0023] In the embodiment of the present invention, the telescopic member 41 can be an electric telescopic rod or a hydraulic telescopic rod, and the telescopic direction of the telescopic member 41 is parallel to the axial direction of the driving shaft 211. When in use, the telescopic member 41 only needs to be controlled to be telescopic, and the telescopic member 41 can drive the connecting ring 42 to move synchronously, thereby driving the sliding sleeve 31 to move along the axial direction of the driving shaft 211 through the connecting ring 42, so that the relative position between each adjusting column 32 and the winding column 22 can be adjusted.

[0024] Specifically, when the telescopic member 41 is extended, the sliding sleeve 31 will move toward the side away from the mounting plate 11, and drive each adjusting column 32 to slide in the direction away from the sliding sleeve 31 through the adjusting connecting rod 33; when the telescopic member 41 is contracted, the sliding sleeve 31 will move toward the side close to the mounting plate 11, and drive each adjusting column 32 to slide in the direction close to the sliding sleeve 31 through the adjusting connecting rod 33.

[0025] like Figure 2 and Figure 7 As shown, as a preferred embodiment of the present invention, the driving unit 5 includes a driving motor 51 mounted on the mounting plate 11, the output end of the driving motor 51 is connected to a driving gear 52, and a transmission gear 53 meshing with the driving gear 52 is installed on the driving shaft 211.

Through the cooperation of the drive gear 52 and the transmission gear 53, the drive motor 51 can drive the drive shaft 211 to rotate synchronously, thereby driving the threaded drive rod 21 to rotate.

When in use, the operator can wind the cold-forged steel wire on the winding column 22, or directly put the whole roll of cold-forged steel wire on the winding column 22. Then control the telescopic member 41 to telescope, and the telescopic member 41 can drive the connecting ring 42 to move synchronously, thereby driving the sliding sleeve 31 to move along the axial direction of the driving shaft 211 through the connecting ring 42, and the sliding sleeve 31 can drive the adjusting column 32 to move synchronously through the adjusting connecting rod 33, thereby driving the plug-in block 24 connected thereto to slide synchronously along the radial direction of the threaded driving rod 21 through each adjusting column 32. Each plug-in block 24 moves toward the side close to the threaded drive rod 21 at the same time, and the plug-in block 24 can drive the outer guard rod 25 to move synchronously until the clamping block 252 at the end of the outer guard rod 25 is clamped into the clamping groove 221, so that the cold heading steel wire can be fixed on the winding column 22. At this time, the inner side of the outer guard rod 25 will abut against the cold heading steel wire, or a certain margin is selected. Then start the drive motor 51, the drive motor 51 can drive the drive gear 52 to rotate, through the cooperation of the drive gear 52 and the transmission gear 53, the drive motor 51 can drive the drive shaft 211 to rotate synchronously, thereby driving the threaded drive rod 21 to rotate, through the cooperation of the threaded drive rod 21 and the internal thread sleeve, the threaded drive rod 21 can drive the winding column 22 to move along its axial direction, thereby sending the cold heading steel wire to be processed into the heat treatment equipment. During the movement of the winding column 22, the connecting seat 23 will drive the guide rod 28 to move synchronously, thereby playing a guiding role, preventing the winding column 22 from rotating, and at the same time increasing the stability of the winding column 22 during the movement.
