Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, specifically a heat treatment device for steel wire. Background Technology

[0002] Steel wire or rod is heated to a temperature above AC3 (850–1000℃) and held at that temperature for a certain time to obtain uniform sorbite. This is then subjected to continuous isothermal cooling (550–650℃) in molten lead to achieve a uniform sorbite structure. This process is commonly referred to as lead quenching in factories. During lead quenching, the wire transmission speed needs to be reduced to ensure the quenching effect; however, this reduces overall production efficiency, and existing quenching chambers occupy a large area.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-4 In this embodiment of the utility model, a steel wire heat treatment device includes a base 1, an electric furnace 2 installed on the base 1, a first eddy current coil 3 installed inside the electric furnace 2, a second fixed frame 14 fixedly connected to the top of the feeding end of the electric furnace 2, and multiple sets of equidistantly distributed second eddy current coils 15 installed inside the second fixed frame 14.

[0024] The electric furnace 2 is equipped with a guide assembly for guiding the steel wire;

[0025] The electric furnace 2 is provided with a third fixed frame 16 fixedly connected to the base 1 at the feeding end. Multiple sets of equidistant feeding components are installed in the third fixed frame 16.

[0026] The discharge end of the electric furnace 2 is provided with a fourth fixing frame 26 fixedly connected to the base 1, and multiple sets of equidistantly distributed material receiving components are installed in the fourth fixing frame 26.

[0027] This invention first releases the steel wire from the feeding assembly, passes it through the second eddy current coil 15 and the guide assembly, and finally winds it onto the receiving assembly. Then, the first eddy current coil 3 heats the lead liquid in the electric furnace 2 to 550-650°C. After that, the second eddy current coil 15 preheats the steel wire to 850-1000°C. Then, under the traction of the receiving assembly and the guidance of the guide assembly, the wire enters the lead liquid in the electric furnace 2, thereby completing the lead quenching.

[0028] The feeding assembly includes a mounting groove 17 fixedly connected to a third fixed frame 16, a mounting frame 18 slidably connected in the mounting groove 17, a positioning pin 19 slidably installed between the mounting frame 18 and the mounting groove 17, a mounting shaft 20 rotatably connected in the mounting frame 18, a mounting base 21 fixedly connected to one end of the mounting shaft 20, a damper installed between the other end of the mounting shaft 20 and the mounting frame 18, a prism 22 fixedly connected to the mounting base 21, a material tray 23 slidably connected to the prism 22, a mounting bolt 24 threadedly connected to the prism 22 on one side of the material tray 23, and a second guide roller 25 rotatably connected to the bottom of the mounting base 21.

[0029] The feeding assembly first achieves quick installation and replacement of multiple sets of mounting frames 18 through the sliding connection between the mounting groove 17 and the mounting frame 18, thereby facilitating the quick replacement of the material tray 23. At the same time, the prism 22 enables relative installation between the mounting shaft 20 and the material tray 23. Then, when feeding material from the material tray 23, the damper applies a damping force to the mounting shaft 20. The damping force is converted into a tension force acting on the steel wire. The tension force and the contraction force generated by the receiving assembly work together to tension the steel wire. At the same time, the second guide wheel guides the fed steel wire, thereby preventing misalignment of the wire feeding caused by the change in the diameter of the material tray 23 as it feeds material.

[0030] The receiving assembly includes a drive shaft 27 rotatably connected within a fourth fixed frame 26. A rotating bearing 28 is rotatably connected to the drive shaft 27, and a mounting frame 18 is fixedly connected to the rotating bearing 28. A positioning pin 19 is slidably installed between the mounting frame 18 and the mounting slide 17. A mounting shaft 20 is rotatably connected within the mounting frame 18. A mounting base 21 is fixedly connected to one end of the mounting shaft 20, and a second gear 30 is fixedly connected to the other end of the mounting shaft 20. A first gear 29 is fixedly connected to the drive shaft 27, and the first gear 29 meshes with the second gear 30. A prism 22 is attached, and a material tray 23 is slidably connected to the prism 22. A mounting bolt 24 threadedly connected to the prism 22 is provided on one side of the material tray 23. A second guide roller 25 is rotatably connected to the bottom of the mounting base 21. A fixed stop bar 32 is fixedly connected to the side of the fourth fixed frame 26 near the electric furnace 2. An insert stop bar 33 is slidably connected to the other side of the fourth fixed frame 26. The material receiving assembly is installed between the fixed stop bar 32 and the insert stop bar 33. A second motor 31 is fixedly connected to the fourth fixed frame 26. The output shaft of the second motor 31 is fixedly connected to the drive end of the drive shaft 27.

[0031] The take-up assembly first drives the drive shaft 27 to rotate via the second motor 31. The drive shaft 27 drives the first gear 29 to rotate. The first gear 29, through meshing with the second gear 30, drives the mounting shaft 20 to rotate. The mounting shaft 20 drives the material tray 23 to rotate, thereby achieving the winding of the lead-quenched steel wire. During this process, the take-up assembly in the fourth fixed frame 26 is axially limited and fixed by the cooperation of the fixed stop bar 32 and the insert stop bar 33, thereby preventing the take-up assembly from shaking during the winding process. When the material tray 23 needs to be replaced after the winding is completed, simply pull out the insert stop bar 33 and pull out the take-up assembly to be replaced to achieve quick replacement of the material tray 23.

[0032] In one instance of this embodiment, please refer to Figures 1-4 The guiding assembly includes fixed seats 4 symmetrically arranged at both ends of the electric furnace 2, fixedly connected to the fixed seats 4. Two sets of rotating shafts 5 are rotatably connected between the fixed seats 4. Multiple sets of equidistant friction rollers 6 are fixedly connected to the rotating shafts 5. A first motor 7 is fixedly connected to the fixed seat 4 on the discharge end side of the electric furnace 2. The output shaft of the first motor 7 is fixedly connected to the drive end of the rotating shaft 5. Drive gears 8 are fixedly connected to the two sets of rotating shafts 5 on the discharge end side of the electric furnace 2. The two sets of drive gears 8 mesh with each other. A first fixed frame 9 is fixedly connected to the base 1. A hydraulic telescopic rod 10 is fixedly connected to the first fixed frame 9. A lifting frame 11 is fixedly connected to the output end of the hydraulic telescopic rod 10. Fixed shafts 12 are fixedly connected to both sides of the lifting frame 11. First guide rollers 13 are fixedly connected to the fixed shafts 12.

[0033] In this invention, when installing the steel wire, the hydraulic telescopic rod 10 is first raised to the top of the friction roller 6. Then, the steel wire is led out from the take-up assembly, passes through the second eddy current coil 15, and then passes between the two sets of friction rollers 6. The upper and lower sets of friction rollers 6 clamp the steel wire, and at this time, the steel wire is located below the first guide roller 13. Then, the hydraulic telescopic rod 10 is extended, and the first guide roller 13 is lowered. At this time, the first guide roller 13 presses the steel wire into the electric furnace 2. Then, during the wire feeding process, the first motor 7 drives the rotating shaft 5 to rotate. The two sets of rotating shafts 5 rotate synchronously in opposite directions under the action of the two sets of drive gears 8. The rotating shafts 5 drive the friction rollers 6 to rotate in the opposite direction to the wire feeding direction, so that the steel wire and the friction rollers 6 rub against each other quickly, thereby quickly brushing off the lead liquid adhering to the surface of the steel wire.
