[0020] Preferably, the present invention further proposes a wire drawing annealing method for wire processing, and a wire drawing annealing device for wire processing proposed above, comprising the following steps:

[0021] S1: Connect the annealing device to the power supply and computer controller, open the box cover, and insert multiple groups of wires through multiple inlet pipes. The multiple groups of wires pass through the first wire pipe and enter the second wire pipe, and then enter the through pipe, the conical sealing ring, the outlet pipe in sequence and extend to the outside of the take-up roller;

[0022] S2: During the annealing operation, the ultrasonic generator works, and the ultrasonic transmitter transmits ultrasonic waves to the surface of the multiple sets of wires. The multiple sets of first wire tubes guide and arrange the multiple sets of wires close together. In order to simultaneously perform ultrasonic processing on the multiple sets of wires, the multiple sets of wires are then guided and unfolded through the multiple sets of second wire tubes and enter the multiple sets of through tubes.

The nitrogen pressure inside the sealed cylinder is monitored by a pressure gauge and transmitted to multiple sets of vertical pipes through the air supply pipe. The nitrogen can be transmitted to the hollow cylinder through the multiple sets of vertical pipes. Since flow control valves are provided on the multiple sets of vertical pipes, the air intake flow inside the multi-column vertical pipes can be controlled. The multiple sets of flow control valves automatically control the flow and adjust so that the nitrogen can flow evenly into the multiple sets of hollow cylinders through the multiple sets of vertical pipes, reducing the nitrogen pressure error inside the multiple sets of hollow cylinders. The nitrogen inside the hollow cylinder is blown into the through-tube through multiple blowing pipes. Since the multiple blowing pipes are set at 45°, the nitrogen is blown in the moving direction of the wire, which can assist the wire pulling and movement. Nitrogen is used as a cooling medium to replace traditional water cooling or air cooling. The cooling speed is controllable and uniform, avoiding quenching stress and reducing the degree of oxidation of the wire annealing.

[0024] S4: The sealing baffle and conical sealing ring are used to guide the wire. The nitrogen is blown towards the sealing baffle, which can block the nitrogen and facilitate recovery.

[0025] S5: When the nitrogen pressure inside the collection box increases, it will enter the sealing cylinder through the recovery pipe and the one-way air outlet valve, and the nitrogen can be recycled;

[0026] S6: During annealing, the servo motor drives the rotating rod to rotate slowly, and the rotating rod drives the take-up roller to rotate. The take-up roller draws and reels the wire. The take-up roller can be removed and replaced by removing the nut.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. Control the operation of the ultrasonic generator. The ultrasonic transmitter transmits ultrasonic waves to the surface of multiple groups of wires. Multiple groups of first wire tubes guide and arrange the multiple groups of wires close together. In order to simultaneously perform ultrasonic processing on multiple groups of wires, multiple groups of wires are guided and unfolded through multiple groups of second wire tubes and enter multiple groups of through-tubes. High-frequency ultrasonic waves are applied during the annealing process. The synergistic effect of ultrasonic effect and lattice vibration is utilized to shorten the annealing time, significantly save energy, refine the grains, improve the dislocation distribution, and increase the fatigue life of the metal wire.

[0029] 2. The nitrogen inside the nitrogen tank is introduced into the sealed cylinder through the nitrogen pipe. The nitrogen pressure inside the sealed cylinder is monitored by a pressure gauge. The nitrogen can be transmitted to the hollow cylinder through the air supply pipe and multiple sets of vertical pipes. Since the multiple sets of vertical pipes are equipped with flow control valves, the air intake flow inside the multi-column vertical pipes can be controlled. The multiple sets of flow control valves automatically control and adjust the flow, so that the nitrogen can flow evenly into the multiple sets of hollow cylinders through the multiple sets of vertical pipes, reducing the nitrogen pressure error inside the multiple sets of hollow cylinders.

[0030] 3. Nitrogen inside the hollow cylinder is blown into the tube through multiple blowing pipes. Since the multiple blowing pipes are set at 45 degrees, the nitrogen is blown in the direction of the wire movement, which can assist the wire pulling movement. Nitrogen is used as a cooling medium to replace traditional water cooling or air cooling. The cooling speed is controllable and uniform, avoiding quenching stress, reducing the degree of wire annealing oxidation, and extending the service life;

[0031] 4. The sealing baffle and conical sealing ring are used to guide the wire. The nitrogen is blown toward the sealing baffle, which can block the nitrogen and facilitate recovery. When the nitrogen pressure inside the collection box increases, it will enter the sealing cylinder through the recovery pipe and the one-way air outlet valve, so that the nitrogen can be recycled and reused to save resources.

[0032] The present invention adopts nitrogen annealing and ultrasonic annealing at the same time, avoiding the single annealing method and improving the annealing effect. Nitrogen replaces traditional water cooling or air cooling, and the cooling speed is controllable and uniform, avoiding quenching stress, reducing the degree of wire annealing oxidation, and extending the service life. Multiple blowing pipes are set at 45°, so that nitrogen is blown in the moving direction of the wire, which can assist the wire pulling movement. BRIEF DESCRIPTION OF THE DRAWINGS

Multiple groups of wire drawing mechanisms 2 are all installed on the top of the working plate 1 and are arranged obliquely for drawing and collecting the wire 8. The collecting box 3 is installed on the top of the working plate 1. The side of the collecting box 3 is open and is provided with a box cover 34 through a hinge. Multiple groups of wire inlet pipes 32 are provided on the right side of the collecting box 3, and multiple groups of wire outlet pipes 33 are provided on the left side of the collecting box 3. The top of the collecting box 3 is open and is provided with a sealing cover 31. The sealing cover 31 A computer controller 9 and an ultrasonic generator 91 are provided on the top. The computer controller 9 is electrically connected to the ultrasonic generator 91. An ultrasonic transmitter head 911 is connected to the ultrasonic generator 91. The ultrasonic transmitter head 911 is installed at the bottom of the sealing cover 31 and is used to transmit ultrasonic waves toward the inside of the collecting box 3. Multiple sets of annealing mechanisms 5 are installed inside the collecting box 3 and are used to anneal the wire 8. The multiple sets of annealing mechanisms 5 and the multiple sets of inlet pipes 32 and the multiple sets of outlet pipes 33 are located on the same horizontal axis. The wire mechanism 6 is arranged inside the collecting box 3 and cooperates with the multiple sets of annealing mechanisms 5 to guide the wire 8. The nitrogen mechanism 4 is arranged on the outside of the working plate 1 and cooperates with the multiple sets of annealing mechanisms 5 to provide nitrogen for the multiple sets of annealing mechanisms 5.

[0050] Specifically, the number of the multiple annealing mechanisms 5 , the multiple inlet pipes 32 , and the multiple outlet pipes 33 is at least five.

[0051] like Figure 1 、 Figure 2 、 Figure 13 As shown, in this embodiment, the wire drawing mechanism 2 includes a bracket 21, which is fixedly mounted on the top of the working plate 1. A rotating rod 24 is rotatably mounted on the bracket 21. A servo motor 22 is fixedly mounted on the outer end of the rotating rod 24. The servo motor 22 is mounted on the outer side of the bracket 21. A limiting plate 23 is fixedly mounted on the outer side of the rotating rod 24. A take-up roller 25 is sleeved on the outer side of the rotating rod 24. A nut 26 is threadedly connected to the outer end of the rotating rod 24. The take-up roller 25 is fixed to the outer side of the rotating rod 24 through the cooperation of the nut 26 and the rotating rod 24.

[0052] Specifically, the servo motor 22 drives the rotating rod 24 to rotate slowly, and the rotating rod 24 drives the take-up roller 25 to rotate. The take-up roller 25 draws and reels the wire 8. The take-up roller 25 can be removed and replaced by removing the nut 26.

[0053] like Figure 4 、 Figure 5 、 Figure 7 、 Figures 9-11As shown, in this embodiment, the annealing mechanism 5 includes two support plates 51, and the tops of the two support plates 51 are provided with bayonet holes 52. The same hollow cylinder 53 is installed in the two bayonet holes 52, and a through-tube 54 is fixedly installed in the hollow cylinder 53. The outer side of the through-tube 54 is provided with a plurality of blowing pipes 541 inside the hollow cylinder 53.

The outer side of the hollow cylinder 53 is connected to a vertical pipe 45, and a flow control valve 451 is provided on the vertical pipe 45. The vertical pipe 45 extends to the top of the sealing cover 31; nitrogen is blown toward the moving direction of the wire 8 to assist the traction movement of the wire 8.

[0054] Specifically, the nitrogen inside the hollow cylinder 53 is blown into the through tube 54 through multiple blowing pipes 541. Since the multiple blowing pipes 541 are set at 45 degrees, the nitrogen is blown toward the moving direction of the wire 8, which can assist in the pulling and movement of the wire 8. Nitrogen is used as a cooling medium to replace traditional water cooling or air cooling. The cooling speed is controllable and uniform, avoiding quenching stress and reducing the degree of annealing oxidation of the wire 8.

[0055] like Figure 7 、 Figure 8 As shown, in this embodiment, the wire mechanism 6 includes a first straight plate 61 and a second straight plate 63, and the first straight plate 61 and the second straight plate 63 are both fixedly mounted on the bottom inner wall of the collecting box 3. The top of the first straight plate 61 is embedded with multiple groups of first wire tubes 62, and the multiple groups of first wire tubes 62 are arranged in a one-to-one correspondence with the multiple groups of incoming wire tubes 32. The top of the second straight plate 63 is embedded with multiple groups of second wire tubes 64, and the incoming wire positions of the multiple groups of second wire tubes 64 are arranged in a one-to-one correspondence with the multiple groups of first wire tubes 62, and the outgoing wire positions of the multiple groups of second wire tubes 64 are arranged in a one-to-one correspondence with the multiple groups of annealing mechanisms 5.

[0056] Specifically, there are five groups of multiple first wire tubes 62 and multiple second wire tubes 64. The multiple groups of first wire tubes 62 guide and arrange the multiple groups of wires 8 close to each other, so that the ultrasonic transmitter 911 can simultaneously perform ultrasonic processing on the multiple groups of wires 8, and then guide the multiple groups of wires 8 through the multiple groups of second wire tubes 64 to expand and enter the multiple groups of through tubes 54.

[0057] like Figure 1-Figure 3 As shown, in this embodiment, the nitrogen mechanism 4 includes a nitrogen tank 41 and a sealing tube 43. The nitrogen tank 41 is located on the outside of the working plate 1. A nitrogen pipe 42 is connected between the nitrogen tank 41 and the sealing tube 43. The nitrogen pipe 42 is connected to a one-way air inlet valve 421. The sealing tube 43 is installed on the top of the working plate 1. The top of the sealing tube 43 is connected to an air supply pipe 44. Multiple groups of vertical tubes 45 are all connected to the air supply pipe 44. The bottom side of the sealing tube 43 is connected to a recovery pipe. The recovery pipe is connected to a one-way air outlet valve 46. The sealing tube 43 is connected to an air pressure gauge 431.

[0058] The present invention also proposes a wire drawing annealing method for wire processing, and a wire drawing annealing device for wire processing proposed above, comprising the following steps:

[0059] S1: Connect the annealing device to the power supply and the computer controller 9, open the box cover 34, and insert multiple groups of wires 8 through the multiple inlet pipes 32. The multiple groups of wires 8 pass through the first wire pipe 62 and enter the second wire pipe 64. Then, they enter the through pipe 54, the conical sealing ring 71, the outlet pipe 33 in sequence, and extend to the outside of the take-up roller 25.

[0060] S2: During the annealing operation, the ultrasonic generator 91 is working, and the ultrasonic transmitter 911 transmits ultrasonic waves to the surface of the plurality of wires 8. The plurality of first wire tubes 62 guide and arrange the plurality of wires 8 close together. In order to simultaneously perform ultrasonic processing on the plurality of wires 8, the plurality of second wire tubes 64 guide and unfold the plurality of wires 8 and enter the plurality of through-tubes 54. During the annealing process, high-frequency ultrasonic waves are applied, and the ultrasonic effect and lattice vibration work together to shorten the annealing time (30%-50% shorter than the traditional process), significantly save energy, refine the grains, improve the dislocation distribution, and increase the fatigue life of the metal wire.

[0061] S3: The nitrogen inside the nitrogen tank 41 is introduced into the sealed cylinder 43 through the nitrogen pipe 42. Since the nitrogen pipe 42 is provided with a one-way air inlet valve 421, the nitrogen can only flow into the sealed cylinder 43. The nitrogen pressure inside the sealed cylinder 43 is monitored by the pressure gauge 431. The nitrogen is transmitted to the multiple groups of vertical pipes 45 through the air supply pipe 44. The nitrogen can be transmitted to the hollow cylinder 53 through the multiple groups of vertical pipes 45. Since the multiple groups of vertical pipes 45 are provided with flow control valves 451, the intake flow inside the multi-column vertical pipes 45 can be controlled. The multiple groups of flow control valves 451 automatically control the nitrogen pressure inside the sealed cylinder 43. The flow rate is controlled and adjusted so that the nitrogen can flow evenly into the multiple groups of hollow cylinders 53 through the multiple groups of vertical tubes 45, reducing the nitrogen pressure error inside the multiple groups of hollow cylinders 53. The nitrogen inside the hollow cylinder 53 is blown into the through-tube 54 through the multiple blowing tubes 541. Since the multiple blowing tubes 541 are set at 45 degrees, the nitrogen is blown in the moving direction of the wire 8, which can assist the wire 8 in pulling and moving. Nitrogen is used as a cooling medium to replace traditional water cooling or air cooling. The cooling speed is controllable and uniform, avoiding quenching stress, reducing the degree of annealing oxidation of the wire 8, and extending the service life.

[0062] S4: When the nitrogen pressure inside the collection box 3 increases, it will enter the sealing cylinder 43 through the recovery pipe and the one-way air outlet valve 46, and the nitrogen can be recycled. The one-way air outlet valve 46 can also be closed to prevent the nitrogen from being recycled. Alternatively, a semiconductor refrigerator can be embedded in the outer side of the sealing cylinder 43, and the cooling surface of the semiconductor refrigerator is located inside the sealing cylinder 43, so as to cool the nitrogen inside the sealing cylinder 43.

[0063] S5: During the annealing process, the servo motor 22 drives the rotating rod 24 to rotate slowly, and the rotating rod 24 drives the take-up roller 25 to rotate. The take-up roller 25 draws and reels the wire 8. The nut 26 is removed and the take-up roller 25 can be removed and replaced.

[0064] Example 2

[0065] like Figure 4 、 Figure 5 、 Figure 8 、 Figure 12 As shown, this embodiment is further optimized on the basis of embodiment one, and the parts identical to the aforementioned technical solutions will not be repeated here. Further, in order to better realize the present invention, the following setting method is particularly adopted: In this embodiment, a sealing partition 7 is fixedly installed on the bottom inner wall of the collecting box 3, and a plurality of groups of conical sealing rings 71 are embedded in the sealing partition 7. The plurality of groups of conical sealing rings 71 are arranged in a one-to-one correspondence with the plurality of groups of outlet pipes 33, and the conical sealing rings 71 are made of high-temperature resistant rubber material.

[0066] In this embodiment, in the working mode, the provided sealing partition 7 and the conical sealing ring 71 are used to guide the wire 8, and the nitrogen is blown toward the sealing partition 7, which can block the nitrogen and facilitate recovery.

[0067] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

10. A wire drawing annealing method for wire processing, used in a wire drawing annealing device for wire processing according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: The annealing device is connected to a power source and a computer controller (9), the box cover (34) is opened, and multiple groups of wires (8) are inserted through multiple inlet pipes (32). The multiple groups of wires (8) pass through the first wire pipe (62) and enter the second wire pipe (64), and then enter the through pipe (54), the conical sealing ring (71), the outlet pipe (33) in sequence and extend to the outside of the take-up roller (25); S2: During the annealing operation, the ultrasonic generator (91) works, the ultrasonic transmitter (911) transmits ultrasonic waves to the surface of the plurality of wires (8), the plurality of first wire tubes (62) guide the plurality of wires (8) to be arranged close together, and the plurality of second wire tubes (64) guide the plurality of wires (8) to be spread out and enter the plurality of through-tubes (54); S3: The nitrogen in the nitrogen tank (41) is introduced into the sealing cylinder (43) through the nitrogen pipe (42). Since the nitrogen pipe (42) is provided with a one-way air inlet valve (421), the nitrogen can only flow into the sealing cylinder (43). The nitrogen pressure inside the sealing cylinder (43) is monitored by the pressure gauge (431). The nitrogen is transmitted to the multiple groups of vertical pipes (45) through the air supply pipe (44). The nitrogen is transmitted to the hollow cylinder (53) through the multiple groups of vertical pipes (45). Since the multiple groups of vertical pipes (45) are all provided with flow control valves (451), the nitrogen pressure inside the multiple column vertical pipes (45) is controlled. The air intake flow rate is automatically controlled and adjusted by multiple flow control valves (451), so that nitrogen can flow evenly into the multiple hollow cylinders (53) through the multiple vertical tubes (45), thereby reducing the nitrogen pressure error inside the multiple hollow cylinders (53). The nitrogen inside the hollow cylinder (53) is blown into the through tube (54) through multiple blowing pipes (541). Since the multiple blowing pipes (541) are set at 45 degrees, the nitrogen is blown toward the moving direction of the wire (8), which can assist the wire (8) in pulling and moving. The nitrogen is used as a cooling medium to reduce the degree of annealing oxidation of the wire (8); S4: The provided sealing partition (7) and the conical sealing ring (71) are used to guide the wire (8), and the nitrogen is blown toward the sealing partition (7), thereby blocking the nitrogen and facilitating recovery; S5: When the nitrogen pressure inside the collection box (3) increases, it will enter the sealing cylinder (43) through the recovery pipe and the one-way air outlet valve (46) to be recycled; S6: During the annealing process, the servo motor (22) drives the rotating rod (24) to rotate slowly, and the rotating rod (24) drives the take-up roller (25) to rotate. The take-up roller (25) draws and reels the wire (8). The nut (26) is removed and the take-up roller (25) is removed and replaced.
