[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-Figure 5 A steel wire processing and quenching device includes a box body 1, a pipe fitting 2 for accommodating the passage of steel wire is horizontally fixed to the outer wall of the box body 1, a feed port 201 is opened at the top of the pipe fitting 2, and a discharge port 202 is opened at the bottom, a filter screen 12 is fixed inside the pipe fitting 2, a heating tube 3 is sleeved on the outside of the pipe fitting 2, one end of the heating tube 3 is rotatably connected to the outer wall of the box body 1, a plurality of scrapers 301 are fixed to the inner wall of the heating tube 3, one side of the scraper 301 is against the outer wall of the pipe fitting 2, an electric spindle 28 is rotatably installed on the box body 1, the end of the electric spindle 28 is fixed to a driving gear 14, a ring gear 13 is fixed to the outer wall of the heating tube 3, and the ring gear 13 is meshed with the driving gear 14.

[0033] Before quenching the steel wire, the pipe fitting 2 is pre-filled with molten salt. Under the action of gravity, the molten salt gathers at the bottom of the pipe fitting 2 and enters the heating tube 3 through the discharge port 202. The liquid level of the molten salt is always lower than the filter 12. The heating tube 3 is heated by electromagnetic induction heating to ensure the temperature inside the tube and prevent the molten salt from solidifying.

[0034] When quenching the steel wire, the steel wire is passed along the axis of the pipe fitting 2, and the electric spindle 28 drives the driving gear 14 to rotate. The rotation of the driving gear 14 drives the ring gear 13 to rotate, and the ring gear 13 drives the heating tube 3 to rotate on the pipe fitting 2. During the rotation of the heating tube 3, the molten salt collected at the bottom of the pipe fitting 2 will be continuously transported to the feed port 201 at the top of the pipe fitting 2. Under the action of gravity, the molten salt continues to fall from the feed port 201 onto the steel wire located on the axis to quench the steel wire. The quenched molten salt will fall on the filter screen 12 under the action of gravity, and after being filtered by the filter screen 12, it will be re-collected at the discharge port 202 at the bottom of the pipe fitting 2, thereby completing the recycling of the molten salt.

[0035] Since the quenched molten salt is filtered by the filter 12, impurities on the surface of the steel wire and oxides formed during the quenching process will be screened out by the filter 12, thereby preventing impurities and oxides in the molten salt from affecting the subsequent quenching of the steel wire.

[0036] like Figure 7-11As shown, a circular heat insulation plate 5 is fixed to the end face of the pipe 2, and a square hole tube 4 with an outer circle and an inner square is rotatably installed on the end face of the heat insulation plate 5. The outer wall of the square hole tube 4 is fixed to the port of the heating tube 3, and two first steel wire brush rollers 7 are rotatably installed on the inner wall of the square hole tube 4. The ends of the two first steel wire brush rollers 7 pass through the wall of the square hole tube 4 and are rotatably connected to the connecting plate 9. A large gear 11 is fixed to the middle part of the connecting plate 9, and a small gear 10 is fixed to the end of one of the first steel wire brush rollers 7, which cooperates with the large gear 10. An end face gear 6 is fixed to the end face of the heat insulation plate 5, and the large gear 11 cooperates with the end face gear 6. A transmission gear 8 is fixed to the two first steel wire brush rollers 7, and the two transmission gears 8 are meshed with each other.

[0037] During the rotation of the heating tube 3, the square hole tube 4 will be driven to rotate synchronously. The rotation of the square hole tube 4 will drive the two first wire brush rollers 7 to revolve around the axis of the pipe fitting 2. During the revolution of the two first wire brush rollers 7, the large gear 11 will be driven to revolve on the end gear 6. During this process, the end gear 6 will drive the large gear 11 to rotate. The rotation of the large gear 11 drives the small gear 10 to rotate. The rotation of the small gear 10 drives one of the first wire brush rollers 7 to rotate. Under the transmission action of the two transmission gears 8, the other first wire brush roller 7 will also rotate accordingly.

[0038] Before the steel wire enters the pipe 2, it passes between the two first steel wire brush rollers 7. The two first steel wire brush rollers 7 that are revolving and rotating at the same time will clean the surface of the steel wire, thereby preventing oxides and impurities on the surface of the steel wire from entering the molten salt and affecting the quenching effect of the molten salt.

[0039] like Figure 5 and Figure 6 As shown, guide wheels 15 are provided on both side walls inside the box body 1 for guiding the steel wire, a plurality of rotating shafts 18 are rotatably installed inside the box body 1, a rolling wheel 19 is fixedly connected to the shaft body of the rotating shaft 18, a plurality of sliding rods 20 are radially fixedly connected inside the rolling wheel 19, a permanent magnet 21 is slidably fitted on the sliding rod 20, a spring 22 is fixedly connected to the sliding rod 20 for applying elastic force to the permanent magnet 21, a connecting rod 16 is fixedly connected to the inner wall of the box body 1, a plurality of magnetic parts 17 are fixedly connected to the connecting rod 16, and the magnetic parts 17 correspond one to one to the rolling wheel 19.

[0040] After the quenching is completed, the steel wire enters the box 1, which is filled with coolant to cool the quenched steel wire.

[0041] After the steel wire enters the box 1, it is guided by the guide wheel 15 to the rolling wheel 19. Under the action of friction, the rolling wheel 19 is driven by the steel wire to rotate. During the rotation of the rolling wheel 19, the distance between the permanent magnet 21 and the magnetic part 17 inside it will change.

[0042] When the distance between the permanent magnet 21 and the magnetic member 17 is the largest, the magnetic attraction between the two is smaller than the elastic force of the spring 22. Under the elastic force of the spring 22, the permanent magnet 21 is closely attached to the axis of the rolling wheel 19.

[0043] When the distance between the permanent magnet 21 and the magnetic part 17 is the smallest, the magnetic force of attraction between the two is greater than the elastic force of the spring 22. Under the action of the magnetic force, the permanent magnet 21 performs centrifugal motion until the permanent magnet 21 impacts the inner wall of the rolling wheel 19. The impact force generated by the permanent magnet 21 impacting the inner wall of the rolling wheel 19 will be transmitted to the steel wire. The steel wire vibrates under the influence of the impact force, and the molten salt condensed on the surface of the steel wire due to cooling will be separated under the action of the vibration.

[0044] like Figure 12 and Figure 13 As shown, a bracket 23 is fixed to the top of the box body 1, and two transmission shafts 26 are rotatably installed on the bracket 23. Synchronous gears 27 are fixed to the two transmission shafts 26 and the two synchronous gears 27 are meshed with each other. A driving gear 29 is fixed to the shaft body of the electric spindle 28, and one of the synchronous gears 27 is meshed with the driving gear 29. A second wire brush roller 24 is rotatably installed on the bracket 23, and the end of the second wire brush roller 24 is connected to the end of the transmission shaft 26 through a universal joint 25.

[0045] The electric spindle 28 drives the driving gear 29 to rotate, and the driving gear 29 drives the synchronous gear 27 to rotate. The simultaneous rotation of the two synchronous gears 27 drives the two transmission shafts 26 to rotate. The rotation of the transmission shaft 26 drives the second wire brush roller 24 to rotate through the universal joint 25. The second wire brush roller 24 rests on the steel wire to clean the solid salt separated from the steel wire to prevent the residual salt from corroding the surface of the steel wire.

[0046] Working principle and workflow:

[0047] After the steel wire passes through the pipe 2 and the box 1 in sequence, it is pulled out of the box 1 by the traction equipment.

[0048] The pipe fitting 2 is pre-filled with molten salt. Under the action of gravity, the molten salt gathers at the bottom of the pipe fitting 2 and enters the heating tube 3 through the discharge port 202. The liquid level of the molten salt is always lower than the filter 12. The heating tube 3 is heated by electromagnetic induction heating to ensure the temperature inside the tube and prevent the molten salt from solidifying.

[0049] Before the steel wire enters the pipe 2, it passes between the two first steel wire brush rollers 7. The two first steel wire brush rollers 7 that are revolving and rotating at the same time will clean the surface of the steel wire, thereby preventing oxides and impurities on the surface of the steel wire from entering the molten salt and affecting the quenching effect of the molten salt.

[0050] When quenching the steel wire, the steel wire is passed along the axis of the pipe fitting 2, and the electric spindle 28 drives the driving gear 14 to rotate. The rotation of the driving gear 14 drives the ring gear 13 to rotate, and the ring gear 13 drives the heating tube 3 to rotate on the pipe fitting 2. During the rotation of the heating tube 3, the molten salt collected at the bottom of the pipe fitting 2 will be continuously transported to the feed port 201 at the top of the pipe fitting 2. Under the action of gravity, the molten salt continues to fall from the feed port 201 onto the steel wire located on the axis to quench the steel wire. The quenched molten salt will fall on the filter screen 12 under the action of gravity, and after being filtered by the filter screen 12, it will be re-collected at the discharge port 202 at the bottom of the pipe fitting 2, thereby completing the recycling of the molten salt.

[0051] After the quenching is completed, the steel wire enters the box 1, which is filled with coolant to cool the quenched steel wire.

[0052] After the steel wire enters the box 1, it is guided by the guide wheel 15 to the rolling wheel 19. Under the action of friction, the rolling wheel 19 is driven by the steel wire to rotate. During the rotation of the rolling wheel 19, the distance between the permanent magnet 21 and the magnetic part 17 inside it will change.

[0053] When the distance between the permanent magnet 21 and the magnetic member 17 is the largest, the magnetic attraction between the two is smaller than the elastic force of the spring 22. Under the elastic force of the spring 22, the permanent magnet 21 is closely attached to the axis of the rolling wheel 19.

[0054] When the distance between the permanent magnet 21 and the magnetic part 17 is the smallest, the magnetic force of attraction between the two is greater than the elastic force of the spring 22. Under the action of the magnetic force, the permanent magnet 21 performs centrifugal motion until the permanent magnet 21 impacts the inner wall of the rolling wheel 19. The impact force generated by the permanent magnet 21 impacting the inner wall of the rolling wheel 19 will be transmitted to the steel wire. The steel wire vibrates under the influence of the impact force, and the molten salt condensed on the surface of the steel wire due to cooling will be separated under the action of the vibration.

[0055] The electric spindle 28 drives the driving gear 29 to rotate, and the driving gear 29 drives the synchronous gear 27 to rotate. The simultaneous rotation of the two synchronous gears 27 drives the two transmission shafts 26 to rotate. The rotation of the transmission shaft 26 drives the second wire brush roller 24 to rotate through the universal joint 25. The second wire brush roller 24 rests on the steel wire to clean the solid salt separated from the steel wire to prevent the residual salt from corroding the surface of the steel wire.

[0056] Compared with the prior art, the steel wire processing and quenching device provided by the present invention pours molten salt from top to bottom on the steel wire when quenching the steel wire online to prevent impurities floating on the surface of the molten salt from covering the surface of the steel wire, and uses the filter screen 12 to clean the metal oxides generated during the heat treatment of the steel wire to prevent impurities such as metal oxides in the molten salt from affecting the quenching quality of the steel wire.

[0057] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
