Description

Technical Field

[0001] The present invention relates to the technical field of steel wire heat treatment, and in particular to a steel wire heat treatment device and a heat treatment process. Background Art

[0002] Heat treatment, a key step in steel wire production, aims to achieve uniform composition and cold-working-compatible microstructure, eliminate work hardening and internal stresses to ensure subsequent processing, and impart the desired mechanical, process, and physical properties to the steel wire. Steel wire heat treatment can be categorized into raw material heat treatment, semi-finished product intermediate heat treatment, and finished product heat treatment. Quenching, a key method of finished product heat treatment, aims to transform all or most of the steel wire microstructure into martensite to achieve high hardness. However, existing heat treatment equipment exhibits significant drawbacks in practical applications: Firstly, quenching efficiency is low, and the quenching fluid cannot be recycled, resulting in resource waste. Secondly, equipment cleaning is difficult, seriously impacting actual performance. The Chinese patent with the announcement number "CN219470134U" discloses a high-speed steel wire heat treatment device that is easy to quench. It realizes automatic quenching of the steel wire by driving the quenching pool through a lifting mechanism, which improves the convenience of operation to a certain extent. However, the device still has obvious shortcomings in actual application: the overall structure is simple and lacks a stable quenching liquid stirring structure, resulting in the quenching liquid being in a static state. It cannot fully contact with the steel wire to improve the quenching efficiency, and it is easy to cause solute precipitation due to static state, affecting the quenching uniformity; at the same time, the steel wire is fixed in the metal placement frame and needs to be manually taken and placed after quenching. It is impossible to realize the dynamic movement adjustment of the steel wire in the quenching liquid, and the overall quenching efficiency is difficult to further improve. The above defects restrict the applicability of the equipment in industrial production. It can be seen that its existing technology has certain defects and shortcomings, so it needs to be improved and designed. Summary of the Invention

[0013] A coating process applied to the aforementioned steel wire heat treatment device comprises the following steps: Step 1: Initial clamping of the steel wire: Place the steel wire to be quenched between the input drive roller and the inner side of the receiving roller, start the electric push rod, and push the concave frame downward through mechanical transmission, so that the drive roller fits the top of the receiving roller, and the anti-slip groove is used to clamp the steel wire; Step 2: Wire extrusion processing: insert the preliminarily installed wire into the inner sides of the extrusion rollers, start the first motor, drive the screw with opposite threads at both ends to rotate, drive the slider to slide in the slide groove, move the connecting block, drive the buffer extrusion group to dislocate, and drive the extrusion rollers to move closer to each other to extrude the wire; Step 3: Clamp the end of the steel wire.

[0014] Beneficial effects of the present invention: 1. During the application of this device, its traction mechanism and buffer mechanism cooperate to realize the automatic and stable transportation and pretreatment of steel wire, and improve the efficiency of heat treatment and quenching of steel wire. During use, the steel wire to be quenched can be placed between the input end drive roller and the receiving roller, and the electric push rod is started to make the drive roller fit the receiving roller. The anti-slip pattern on its surface ensures a stable clamping. After the steel wire passes through the squeezing roller, the first motor drives the screw rod with opposite threads at both ends to rotate, driving the slider to make the squeezing roller squeeze the steel wire. After the outer end of the steel wire is clamped by the output end roller group, the second motor drives the drive roller to rotate, and cooperates with the receiving roller to send the steel wire into the quenching tank. The quenching treatment is completed during movement, which greatly improves the efficiency of steel wire heat treatment. 2. This device is equipped with a stirring mechanism to ensure that the quenching liquid can fully exert its efficiency and improve the quenching effect. During heat treatment quenching, the third motor drives the rotating shaft to drive the stirring plate and the auger to rotate. The stirring plate stirs the quenching liquid in the middle of the quenching pool. The auger with opposite threads at both ends pushes the quenching liquid from the inside to the outside, forming water pressure to promote the quenching liquid to circulate through the circulating pipe rack, delivery pipe, cross pipe and reflux pipe. The circulating flow combined with the action of the stirring plate makes the quenching liquid roll evenly, increases the comprehensive contact between the steel wire and the quenching liquid, prevents solute precipitation, stabilizes the performance of the quenching liquid, and improves the overall quenching effect. 3. During the heat treatment, the device can flexibly adjust the quenching process according to the material characteristics of the steel wire to improve the adaptability. By controlling the first motor to squeeze or separate the steel wire, the degree of bending of the steel wire is changed, and the contact area and residence time in the quenching pool are adjusted to meet different quenching requirements. At the same time, the driving roller and the receiving roller can synchronously clamp multiple groups of steel wires. During quenching, the telescopic spring buffers the stress, and the support shaft guides the spring to stably extend and retract to ensure stable steel wire transmission. This enables the device to continuously quench ultra-long steel wires, significantly improving efficiency compared to traditional methods, and achieving stable, efficient and comprehensive steel wire quenching treatment.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention. Example 1

[0018] A steel wire heat treatment device includes a base 1, support legs 2 are fixedly installed at the four corners of the top of the base 1, a top frame 3 is fixedly installed on the top of the support legs 2, a heat treatment quenching pool 4 is fixedly installed on the inner side of the top frame 3, a stirring mechanism 5 is movably installed at the lower end of the heat treatment quenching pool 4, a traction mechanism 6 is fixedly installed on both sides of the top of the heat treatment quenching pool 4, and a buffer mechanism 7 is movably installed inside the heat treatment quenching pool 4; The buffer mechanism 7 includes a power assembly 71, which is arranged in the middle of the rear side of the heat treatment quenching pool 4. The upper and lower ends of the front of the power assembly 71 are fixedly installed with connecting blocks 72, and the ends of the connecting blocks 72 are fixedly installed with connecting plates 73. The front of the connecting plates 73 are evenly spaced and linearly arranged with buffer extrusion groups 74. The buffer extrusion groups 74 between the upper and lower connecting plates 73 are staggered. During the use of this device, when the steel wire heat treatment device is working, the base 1 firmly supports the top frame 3 through the four corner support legs 2. The heat treatment quenching pool inside the top frame 3 is used to accommodate quenching liquid. When in use, the steel wire is placed between the driving roller 64 and the receiving roller 67 of the traction mechanism 6. The traction mechanism 6 realizes the up and down movement of the driving roller 64 through the electric push rod 62 and other components, completes the clamping and fixation of the steel wire, and stably transports the steel wire into the quenching pool under the drive of the motor, stirring The mixing mechanism 5 is located at the lower end of the quenching pool. After it is started, it can drive the quenching liquid to circulate, so that the temperature of the quenching liquid is uniform and the performance is stable. The power component 71 of the buffer mechanism 7 is set in the middle of the rear side of the quenching pool. After the power component 71 is started, the connecting blocks 72 at the upper and lower ends of its front face are displaced under the action of power, driving the end connecting plates 73 to move. Since the front faces of the connecting plates 73 are fixedly installed with staggered buffer extrusion groups 74 at equal intervals, when the connecting plates 73 move, the buffer extrusion groups 74 move accordingly, thereby squeezing the steel wire passing through them. During this extrusion process, the buffer extrusion group 74 can absorb the stress generated by the uneven force on the steel wire through the elastic structure or buffer component while applying pressure to the steel wire, thereby avoiding damage to the steel wire due to rigid extrusion, and at the same time changing the travel path of the steel wire in the quenching pool, increasing its contact area and time with the quenching liquid, and assisting in completing the quenching process.

[0019] Combine Figures 1-6 and Figure 8As shown, the power assembly 71 includes a slide 711 and a first motor 712. The first motor 712 is fixedly installed in the middle of the lower end of the rear side of the heat treatment quenching pool 4. The slide 711 is opened in the middle of the rear side of the heat treatment quenching pool 4. The internal rotation of the slide 711 is connected to a screw rod 714. The bottom of the screw rod 714 is connected to the output end of the first motor 712. The outer surface of the screw rod 714 is threadedly connected to a slider 713. The threads at both ends of the screw rod 714 rotate in opposite directions. The front of the slider 713 is fixedly connected to the connecting block 72. The buffer extrusion group 74 includes a fixing plate 741, a fixing plate 741, etc. The spacing is linearly arranged and fixedly installed on the front side of the connecting plate 73. The fixed plates 741 on the upper and lower groups of connecting plates 73 are opposite to each other and staggered. The inner side of the fixed plate 741 is fixedly installed with a mounting plate 742. The inner ends of the mounting plate 742 are evenly spaced and linearly arranged and fixedly connected with telescopic springs 743. The inner side of the telescopic spring 743 is fixedly installed with a concave seat 744. The inner side of the concave seat 744 is rotatably connected to an extrusion roller 745. The outer ends of the concave seat 744 are fixedly installed with a support shaft 746. The outer end of the support shaft 746 passes through the mounting plate 742 and the fixed plate 741.

[0020] According to the technical solution in the embodiment of the present application, during use of the device, when the first motor 712 is started, it is fixedly installed in the middle of the lower end of the rear side of the heat treatment quenching tank, and the operation of the motor drives the screw rod 714 to rotate. Because the threads at both ends of the screw rod 714 rotate in opposite directions, the slider 713 threaded on the outer surface will slide towards or away from each other in the slide groove 711. The front of the slider 713 is fixedly connected to the connecting block 72. When the slider 713 slides, it drives the connecting block 72 to move, thereby causing the connecting plate 73 to move accordingly. The fixed plates 741 are arranged at equal intervals on the front of the connecting plate 73, and the upper and lower groups are opposite to each other and staggered. The two ends of the mounting plate 742 on the inner side of the fixed plate 741 are connected to the telescopic springs 743. The inner side of the spring The concave seat 744 is fixed, and the connecting squeezing roller 745 is rotated inside the concave seat 744. When the connecting plate 73 moves, the fixed plate 741, the mounting plate 742 and the squeezing roller 745 are driven to move synchronously. The squeezing roller 745 squeezes the steel wire passing through it. During the squeezing process, if the steel wire is unevenly stressed, the telescopic spring 743 can absorb the stress through elastic deformation and play a buffering role; the support shaft 746 on the outside of the concave seat 744 passes through the mounting plate 742 and the fixed plate 741, guides the expansion and contraction direction of the telescopic spring 743, ensures that the spring is stably expanded and contracted, and makes the squeezing roller 745 stably act on the steel wire, while adjusting the travel path of the steel wire in the quenching tank, ensuring that the steel wire will not be damaged due to rigid extrusion. Example 2

[0021] Combine Figure 1-Figure 7As shown, the traction mechanism 6 includes a fixed frame 61, which is fixedly installed on both sides of the top of the heat treatment quenching pool 4. The top of the fixed frame 61 is fixedly connected to an electric push rod 62, and the output end of the electric push rod 62 passes through the fixed frame 61 and is fixedly installed with a concave frame 63. The inside of the concave frame 63 is rotatably connected to a driving roller 64, and one end of the concave frame 63 is fixedly connected to a second motor 65. The output end of the second motor 65 is fixedly connected to one side of the driving roller 64. The outer surface of the driving roller 64 is provided with anti-slip grooves 66 at equal intervals, and the inner lower end of the fixed frame 61 is rotatably connected to a receiving roller 67.

[0022] The technical solution in the above-mentioned embodiment of the present application is that during the use of the device, when the traction mechanism 6 is working, the fixed frame 61 is fixed on both sides of the top of the heat treatment quenching pool to provide support. After the steel wire to be processed is placed between the driving roller 64 and the receiving roller 67, the electric push rod 62 on the top of the fixed frame 61 is started, and its output end pushes the concave frame 63 to move downward, so that the driving roller 64 in the concave frame 63 gradually approaches and fits the receiving roller 67. The anti-slip groove 66 on the outer surface of the driving roller 64 cooperates with the receiving roller 67 to increase the friction between the driving roller 64 and the receiving roller 67, thereby firmly clamping the steel wire. At this time, the second motor 65 fixed to one end of the concave frame 63 is started, and the output end of the second motor 65 drives the driving roller 64 to rotate. The friction between the driving roller 64 and the receiving roller 67 is used to drive the steel wire to move into the heat treatment quenching pool, thereby realizing stable transportation of the steel wire and preparing for subsequent quenching treatment. It is convenient to carry out automatic feeding quenching and discharge after quenching, and automatic quenching treatment can be realized. Example 3

[0023] Combine Figure 1-Figure 3 and Figure 5-Figure 6As shown, the stirring mechanism 5 includes a third motor 51, a stirring assembly 52 and a circulation assembly 53. The third motor 51 is fixedly installed at the lower end of one side of the heat treatment quenching pool 4. The output end of the third motor 51 passes through the heat treatment quenching pool 4. The stirring assembly 52 is rotatably connected to the inner lower end of the heat treatment quenching pool 4. The circulation assembly 53 is fixedly installed on both sides of the heat treatment quenching pool 4. The output end of the third motor 51 is connected to one end of the stirring assembly 52. The stirring assembly 52 includes a rotating shaft 521, which is rotatably connected to the inner lower end of the heat treatment quenching pool 4. The outer surface of the rotating shaft 521 is fixedly installed with stirring plates 522 arranged in a ring at equal intervals. Augers 523 are fixedly installed at both ends of the rotating shaft 521. The two screw dragons 523 at both ends of the rotating shaft 521 have opposite thread rotation directions, and the circulation component 53 includes a circulation pipe rack 531, which is fixedly installed on the lower ends of both sides of the heat treatment quenching pool 4. The outer end of the circulation pipe rack 531 is fixedly connected to the delivery pipe 532, and the end of the delivery pipe 532 passes through the upper ends of both sides of the heat treatment quenching pool 4 and is fixedly installed with a horizontal pipe 533. The inner side of the horizontal pipe 533 is fixedly installed with a reflux pipe 534 in a linear arrangement at equal intervals. The input end of the circulation pipe rack 531 is connected to the lower end of the interior of the heat treatment quenching pool 4, and the bottom of the quenching pool is arranged in an arc shape as a whole. By setting a quenching pool with an arc-shaped bottom, it is convenient to adapt to the stirring mechanism 5 for stirring, thereby improving the stirring effect.

[0024] According to the technical solution in the embodiment of the present application, when the device is in use, the stirring mechanism 5 is in operation, and the third motor 51 fixed to the lower end of one side of the heat treatment quenching pool is started, and its output end passes through the quenching pool and is connected to the rotating shaft 521 of the stirring assembly 52 and drives the rotating shaft 521 to rotate. The stirring plates 522 on the outer surface of the rotating shaft 521 are arranged in a ring shape. As the rotating shaft 521 rotates, the quenching liquid at the lower end of the quenching pool is stirred to promote the flow and mixing of the quenching liquid. At the same time, the screw dragons 523 with opposite thread rotation directions at both ends of the rotating shaft 521 rotate synchronously, generating a driving force from the inside to the outside of the quenching pool, pushing the quenching liquid from the inside to the outside, and under the action of the screw dragon 523 Under the use, the quenching liquid forms water pressure and flows into the delivery pipe 532 from the lower end of the quenching pool through the circulation pipe rack 531. The delivery pipe 532 delivers the quenching liquid to the horizontal pipe 533 that runs through the upper ends of both sides of the quenching pool. The reflux pipes 534 arranged at equal intervals on the inside of the horizontal pipe 533 inject the quenching liquid back into the quenching pool to achieve the circulation of the quenching liquid. The stirring of the stirring plate 522 and the liquid delivery of the circulation component 53 cooperate with each other to promote the uniform rolling of the quenching liquid in the pool, ensure the uniform temperature and stable performance of the quenching liquid, and improve the quenching effect of the steel wire. A drain valve is installed on one side of the bottom of the quenching pool. The drain valve can discharge the quenching liquid after quenching is completed, which is convenient for the use of this equipment.

[0025] A coating process for a steel wire heat treatment device comprises the following steps: Step 1: Initial clamping of the steel wire: Place the steel wire to be quenched between the input drive roller 64 and the inner side of the receiving roller 67, start the electric push rod 62, and push the concave frame 63 downward through mechanical transmission, so that the drive roller 64 fits the top of the receiving roller 67, and the anti-slip groove 66 is used to clamp the steel wire; Step 2: Wire extrusion processing: insert the preliminarily installed wire into the inner sides of the extrusion rollers 745, start the first motor 712, drive the screw rod 714 with two ends rotating in opposite directions to rotate, drive the slider 713 to slide in the slide groove 711, move the connecting block 72, drive the buffer extrusion group 74 to dislocate, and drive the extrusion rollers 745 to move closer to each other to extrude the wire; Step 3: Clamp the end of the steel wire. Place the outer end of the steel wire between the receiving roller 67 at the output end and the inner side of the driving roller 64. Start the electric push rod 62 again to complete the clamping of the other end of the steel wire. Step 4: The steel wire is transported into the tank, and the second motor 65 is started to drive the driving roller 64 to rotate. The driving roller 64 cooperates with the receiving roller 67 to stably transport the steel wire into the heat treatment quenching tank; Step 5: Circulating and stirring the quenching liquid. During heat treatment and quenching, the third motor 51 is started to drive the rotating shaft 521 to rotate, which in turn drives the stirring plate and the auger 523 with oppositely rotating threads at both ends to rotate. The stirring plate stirs the quenching liquid in the middle of the quenching tank, and the auger 523 pushes the quenching liquid from the inside out, generating water pressure, causing the quenching liquid to circulate through the circulation pipe rack 531, the delivery pipe 532, the cross pipe 533, and the reflux pipe 534. Step 6: Adjust the quenching process. According to the material properties of the steel wire, start the first motor 712 to control the sliding of the slider 713 and adjust the degree of squeezing of the steel wire by the squeezing roller 745; or reverse the screw rod 714 to separate the squeezing roller 745, change the contact area and residence time of the steel wire in the quenching pool, drive the roller 64 and the receiving roller 67 to synchronously clamp multiple groups of steel wires, use the telescopic spring 743 and the support shaft 746 to ensure stable transmission, and complete continuous quenching.

[0026] The use principle and advantages of the present invention are as follows: during use, the traction mechanism 6 and the buffer mechanism 7 of the device cooperate with each other to perform stable automatic transportation, improve the efficiency of the heat treatment of the steel wire, and quickly complete the stable transportation and pretreatment of the steel wire. During use, the steel wire to be quenched can be placed between the input end driving roller 64 and the inner side of the receiving roller 67, and the electric push rod 62 is started. It pushes the concave frame 63 downward through mechanical transmission, and the concave frame 63 drives the internal driving roller 64 to gradually fit the top of the receiving roller 67. The surfaces of the driving roller 64 and the receiving roller 67 are provided with anti-skid patterns 66. When the two fit together, the anti-skid patterns 66 increase the friction force to achieve a firm clamping of the steel wire. After the steel wire is initially installed, it is inserted between the inner sides of the squeezing rollers 745, and the first motor 712 is started. The motor drives The screw rod 714 rotates. Since the threads at both ends of the screw rod 714 rotate in opposite directions, the two sliders 713 are synchronously driven to slide against each other in the slide groove 711 during rotation. The sliding of the slider 713 drives the connecting block 72 to move, thereby causing the buffer extrusion group 74 on the connecting plate 73 to be dislocated. As the screw rod 714 continues to rotate, the slider 713 drives the extrusion rollers 745 to move closer to each other, extruding the steel wire. Afterwards, the outer end of the steel wire is placed between the receiving roller 67 at the output end and the inner side of the driving roller 64, and the electric push rod 62 is started again to complete the clamping of the other end of the steel wire. At this time, the second motor 65 is started, which drives the driving roller 64 to rotate. The driving roller 64 and the receiving roller 67 cooperate with each other to stably transmit the steel wire to the heat treatment quenching tank, so that the steel wire is quenched by the quenching liquid during the movement; The stirring mechanism 5 ensures that the quenching liquid plays a full role. When the heat treatment quenching is carried out, the third motor 51 is started, and the motor drives the rotating shaft 521 to rotate. The rotating shaft 521 drives the stirring plate and the auger 523 to rotate together. The stirring plate is located in the middle of the quenching pool. During the rotation process, the quenching liquid in the middle of the quenching pool is stirred to promote the flow and mixing of the quenching liquid in the middle area. At the same time, the auger 523 installed at both ends of the rotating shaft 521 also rotates accordingly. The threads of the two auger 523 rotate in opposite directions. During the rotation process, a driving force is generated from the inside to the outside of the quenching pool, pushing the quenching liquid from the inside to the outside, forming water pressure. The quenching liquid in the quenching pool flows into the delivery pipe 532 through the circulation pipe rack 531, and is then delivered to the transverse pipe 533 through the delivery pipe 532. Finally, it flows back into the quenching pool through the reflux pipe 534 at the transverse pipe 533, thus realizing the circulation of the quenching liquid. This circulation combined with the stirring of the stirring plate not only promotes the stable up and down flow of the quenching liquid, but also allows the quenching liquid to roll more evenly and comprehensively in the pool. On the one hand, it makes the contact between the steel wire and the quenching liquid more complete, thereby improving the comprehensiveness of the quenching; on the other hand, it effectively avoids the precipitation of solutes in the quenching liquid, ensures the stability of the quenching liquid performance, and thus improves the overall quenching effect. In addition, the present device can also flexibly adjust the quenching process according to the material characteristics of the steel wire. During the quenching process, by starting the first motor 712 to drive the slider 713 to slide further, the squeezing roller 745 can further squeeze the steel wire, thereby increasing the bending degree of the steel wire. After the bending degree of the steel wire increases, the contact area with the quenching liquid increases when moving in the quenching pool, and the residence time is prolonged, thereby improving the quenching effect. If it is necessary to shorten the quenching time, the first motor 712 is started to drive the screw rod 714 to reverse, and the upper and lower sets of squeezing rollers 745 are driven to separate from each other, thereby reducing the squeezing of the steel wire and allowing the steel wire to pass through the quenching pool quickly. This adjustment method can flexibly control the processing time of the steel wire in the quenching pool according to the characteristics of different steel wire materials, and meet the needs of diversified heat treatment. Processing needs; It is worth mentioning that the driving roller 64 and the receiving roller 67 have the ability to synchronously clamp multiple groups of steel wires. During the quenching process, the telescopic spring 743 plays a buffering role. When the force on the steel wire changes, the telescopic spring 743 absorbs stress through elastic deformation, which has the effect of tensioning and buffering. The support shaft 746 is set to provide guidance for the telescopic spring 743 to ensure that the spring is stably extended and contracted to avoid offset or jamming, thereby ensuring the stability of the steel wire during the transmission process. This enables the device to continuously and uninterruptedly quench extra-long steel wires. Compared with the traditional single processing method, the quenching efficiency is significantly improved, allowing the equipment to complete the steel wire quenching processing task more stably, efficiently and comprehensively during actual use.

[0027] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
