Detailed implementation manners

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0024] As Figures 1 - 6 shown, a cold heading steel wire heat treatment device provided by an embodiment of the present invention includes a base 1, on which a mounting plate 11 is installed, and further includes:

[0025] Feeding module 2, the feeding module 2 includes a threaded drive rod 21 rotatably mounted on the mounting disc 11, and a plurality of plug-in blocks 24 mounted on the mounting disc 11. A drive unit 5 for driving the threaded drive rod 21 to rotate is further provided on the mounting disc 11. The plug-in blocks 24 are arranged in a ring around the threaded drive rod 21 and can slide along the radial direction of the threaded drive rod 21. An adjusting unit 3 for driving each plug-in block 24 to move simultaneously along the radial direction of the threaded drive rod 21 is further mounted on the mounting disc 11. A winding column 22 is sleeved on the threaded drive rod 21, and an internal threaded hole matching the threaded drive rod 21 is provided inside the winding column 22. A plurality of connecting seats 23 are annularly mounted at one end of the winding column 22 close to the mounting disc 11. One end of the connecting seat 23 is connected with a guide rod 28. The guide rod 28 penetrates through the mounting disc 11 and can slide along the axial direction of the threaded drive rod 21. An outer protection rod 25 is slidably mounted on each connecting seat 23. An insertion hole 251 for matching the plug-in block 24 is formed at one end of the outer protection rod 25 close to the connecting seat 23. A positioning plug 26 is slidably mounted in the insertion hole 251, and the positioning plug 26 is connected with the inside of the insertion hole 251 through a return spring 27. Positioning grooves 231 matching the positioning plug 26 are equidistantly distributed on the connecting seat 23. A clamping block 252 is arranged at one end of the outer protection rod 25 away from the connecting seat 23, and a clamping groove 221 matching the clamping block 252 is arranged at one end of the winding column 22 away from the mounting disc 11.

[0026] In an embodiment of the present invention, in the initial state, one end of the winding column 22 abuts against the mounting disc 11, and each outer guard rod 25 is in a state away from the winding column 22 (that is, the distance between the winding column 22 and the outer guard rod 25 is the largest), and at this time, the plugging block 24 will be plugged into the plugging hole 251. Through the plugging block 24, the positioning plug 26 will be pushed out of the positioning groove 231, and the return spring 27 will be in a compressed state. When in use, the operator can wind the cold heading steel wire around the winding column 22, or directly sleeved the whole roll of cold heading steel wire on the winding column 22. Then start the adjusting unit 3. Through the adjusting unit 3, drive each plugging block 24 to move simultaneously towards the side close to the threaded driving rod 21. The plugging 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, then 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 can be left. Then start the driving unit 5. Through the driving unit 5, drive the threaded driving rod 21 to rotate. Through the cooperation of the threaded driving rod 21 and the internal thread sleeve, the threaded driving rod 21 can drive the winding column 22 to move along its axial direction, so as to send the cold heading steel wire to be processed into the heat treatment equipment. And in this process, the outer guard rod 25 will be separated from the plugging block 24. At this time, under the action of the elastic restoring force of the return spring 27, the positioning plug 26 will be plugged into the positioning groove 231, so as to fix the position of the outer guard rod 25. During the movement of the winding column 22, the connecting seat 23 will drive the guiding rod 28 to move synchronously, so as to play a guiding role, prevent the winding column 22 from rotating, and at the same time increase the stability of the winding column 22 during the movement process.

[0027] As Figure 2 and Figure 7 shown, as a preferred embodiment of the present invention, a driving shaft 211 is connected to the end of the threaded driving rod 21, and the driving shaft 211 and the threaded driving rod 21 are respectively located on both sides of the mounting disc 11.

[0028] As Figure 2 and Figure 7 shown, as a preferred embodiment of the present invention, the adjusting unit 3 includes a sliding sleeve 31 sleeved on the driving shaft 211 (the driving shaft 211 does not drive the sliding sleeve 31 to rotate), and a number of adjusting columns 32 distributed in a ring around the sliding sleeve 31. A moving unit 4 for driving the sliding sleeve 31 to move along the axial direction of the driving shaft 211 is provided on the mounting disc 11. The number of the adjusting columns 32 is the same as the number of the plugging blocks 24, and each of the adjusting columns 32 is respectively connected to each of the plugging blocks 24. Two adjusting connecting rods 33 are rotatably installed on the side of the adjusting column 32 close to the sliding sleeve 31, and the end of the adjusting connecting rod 33 away from the adjusting column 32 is rotatably installed on the side wall of the sliding sleeve 31.

[0029] In an embodiment of the present invention, during use, only need to drive the sliding sleeve 31 to move along the drive shaft 211 through the moving unit 4. The sliding sleeve 31 can drive the adjusting column 32 to move synchronously through the adjusting link 33, so as to drive the plug-in block 24 connected thereto to slide synchronously along the radial direction of the threaded drive rod 21 through each adjusting column 32.

[0030] As Figure 2 and Figure 7 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 with a connecting ring 42, and the connecting ring 42 is connected with the side wall of the sliding sleeve 31.

[0031] In an 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 drive shaft 211. During use, only need to control the telescopic member 41 to expand and contract. The telescopic member 41 can drive the connecting ring 42 to move synchronously, so as to drive the sliding sleeve 31 to move along the axial direction of the drive shaft 211 through the connecting ring 42, and then the relative position between each adjusting column 32 and the winding column 22 can be adjusted.

[0032] Specifically, when the telescopic member 41 extends, the sliding sleeve 31 will move towards 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 link 33; when the telescopic member 41 contracts, the sliding sleeve 31 will move towards 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 link 33.

[0033] As Figure 2 and Figure 7 shown, as a preferred embodiment of the present invention, the driving unit 5 includes a driving motor 51 installed on the mounting plate 11. The output end of the driving motor 51 is connected with a driving gear 52, and a transmission gear 53 meshing with the driving gear 52 is installed on the drive shaft 211.

[0034] In an embodiment of the present invention, during use, only need to start the driving motor 51. The driving motor 51 can drive the driving gear 52 to rotate. Through the cooperation of the driving gear 52 and the transmission gear 53, the driving motor 51 can drive the drive shaft 211 to rotate synchronously, so as to drive the threaded drive rod 21 to rotate.

[0035] Working principle: In the initial state, one end of the winding column 22 abuts against the mounting disc 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). At this time, the insertion block 24 will be inserted into the insertion hole 251. Through the insertion block 24, the positioning insertion block 26 will be pushed out of the positioning groove 231, and the return spring 27 will be in a compressed state. When in use, the operator can wind the cold heading wire around the winding column 22, or directly sleeved the whole roll of cold heading wire on the winding column 22. Then control the telescopic member 41 to expand and contract. The telescopic member 41 can drive the connecting ring 42 to move synchronously, so as to drive the sliding sleeve 31 to move along the axial direction of the driving shaft 211 through the connecting ring 42. The sliding sleeve 31 can drive the adjusting column 32 to move synchronously through the adjusting link 33, so as to drive the insertion block 24 connected thereto to slide synchronously along the radial direction of the threaded driving rod 21 through each adjusting column 32. Each insertion block 24 moves simultaneously towards the side close to the threaded driving rod 21. The insertion 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, and the cold heading 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 wire, or a certain margin can be left. Then start the driving motor 51. The driving motor 51 can drive the driving gear 52 to rotate. Through the cooperation of the driving gear 52 and the transmission gear 53, the driving motor 51 can drive the driving shaft 211 to rotate synchronously, so as to drive the threaded driving rod 21 to rotate. Through the cooperation of the threaded driving rod 21 and the internal thread sleeve, the threaded driving rod 21 can drive the winding column 22 to move along its axial direction, so as to feed the cold heading 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, so as to play a guiding role, prevent the winding column 22 from rotating, and at the same time increase the stability of the winding column 22 during the movement process.

[0036] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
