Description

Technical Field

[0001] This invention belongs to the technical field of heat treatment equipment, and specifically relates to a continuous intelligent heat treatment equipment for steel strips. Background Technology

[0002] Continuous intelligent heat treatment equipment for steel strips is typically a high-frequency induction heating device. Its principle is as follows: when a high-frequency current passes through an induction coil, a high-frequency alternating magnetic field is generated. When a conductor such as a metal is placed in this magnetic field, according to the law of electromagnetic induction, an induced electromotive force is generated within the conductor, thus forming eddy currents. Due to the inherent resistance of the metal conductor, these eddy currents generate heat within the metal, causing the metal object to heat up rapidly, achieving the heating purpose.

[0003] When continuously processing steel strips, high-frequency induction heating equipment is required. When using existing high-frequency induction heating equipment, if the steel strip has uneven surfaces when passing through the coil of the high-frequency induction heating equipment, the distance between the upper and lower surfaces of the steel strip and the coil will be different, which will affect the uniformity of heating.

[0004] Therefore, it is necessary to invent a continuous intelligent heat treatment device for steel strips to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a continuous intelligent heat treatment device for steel strips, thereby resolving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a continuous intelligent heat treatment device for steel strips, comprising:

[0007] The main body of the equipment is used for heat treatment;

[0008] The mounting housings are symmetrically arranged on the device body;

[0009] The uniform heating components are equidistantly arranged on the mounting shell, which can uniformly heat the steel strip;

[0010] The uniform heating component includes:

[0011] An opening is provided on the surface of the mounting housing; a vertical plate is provided on the surface of the mounting housing; a slider is slidably mounted inside the vertical plate; and an induction coil is connected to the outside of the slider.

[0012] A push rod, connected to the induction coil, is used to adjust the position of the induction coil;

[0013] A first spring connects the slider to the vertical plate;

[0014] A power supply module, located inside the mounting housing, is used to provide energy to the induction coil to heat up the steel strip for heat treatment.

[0015] Furthermore, the induction coil is provided with a correction component for correcting the position of the push rod;

[0016] The corrective components include:

[0017] A carrier plate is disposed on the surface of the induction coil;

[0018] A bracket is attached to the outside of the carrier plate;

[0019] The slide bar is slidably mounted on the bracket;

[0020] A connecting assembly for connecting the slide bar to the top bar;

[0021] A fixing component is used to fix the top rod;

[0022] A limiting component is used to limit the position of the push rod in the vertical direction;

[0023] The second spring, sleeved on the outside of the slide rod, is used to drive the top rod to move in the vertical direction.

[0024] Furthermore, the connection component includes:

[0025] A connecting rod is connected to one end of the slide rod, and the connecting rod is inserted into the inside of the top rod;

[0026] A bolt is used to connect the top rod to the connecting rod. A second spring is disposed between the connecting plate and the bracket, and the second spring connects the bracket to the connecting plate.

[0027] Furthermore, the fixing component includes:

[0028] Electric push rods, which are symmetrically arranged on the carrier plate;

[0029] A push block is connected to one end of the electric push rod;

[0030] A clamping block is attached to the top of the push block.

[0031] Furthermore, the limiting component includes:

[0032] A baffle is slidably mounted on the device body;

[0033] Gears are rotatably mounted inside the main body of the device;

[0034] Teeth are equidistantly arranged on the surface of the baffle, and the teeth mesh with the gear.

[0035] An electric motor is connected inside the main body of the device, and the output shaft of the motor is connected to the middle of one side of the gear.

[0036] Furthermore, the power supply module includes:

[0037] The power supply is located inside the mounting housing;

[0038] A power cord connects the power source to the induction coil. A wire passage is provided on the vertical plate, through which the power cord passes.

[0039] Furthermore, the top rods located above and below are symmetrically arranged, and the top rods can withstand the heat generated when the induction coil is heated.

[0040] Furthermore, when the baffle moves between the two opposing induction coils, the distance between the baffle and the upper induction coil is the same as the distance between the baffle and the lower induction coil.

[0041] Furthermore, the elastic force of the second spring is less than that of the first spring.

[0042] Furthermore, when the clamping block abuts against the top rod, the friction between the clamping block and the top rod can fix the top rod.

[0043] The technical effects and advantages of this invention are as follows:

[0044] 1.

[0045] 2. This invention can correct the push rod, so that the distance between the upper and lower distributed push rods and their respective induction coils is consistent. This ensures that the distance between the end of the push rod and the induction coil will not change due to wear during subsequent use, thus ensuring uniform heating. Attached Figure Description

Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0054] This invention provides a continuous intelligent heat treatment device for steel strips, such as... Figures 1 to 6 As shown, it includes: the device body 1, the mounting shell 2, and the uniform heating component;

[0055] The equipment body 1 is used for heat treatment. The equipment body 1 is a high-frequency induction heating device. The mounting shell 2 is symmetrically fixed on the equipment body 1. The uniform heating components are equidistantly arranged on the mounting shell 2, which can uniformly heat the steel strip.

[0056] The uniform heating component includes: an opening 3, a vertical plate 4, a slider 5, an induction coil 6, a push rod 7, a first spring 8, and a power supply module;

[0057] An opening 3 is set on the surface of the mounting shell 2. A vertical plate 4 is fixedly installed on the surface of the mounting shell 2. A slider 5 is slidably installed inside the vertical plate 4. An induction coil 6 is fixedly connected to the outside of the slider 5. A push rod 7 is connected to the induction coil 6 and is used to adjust the position of the induction coil 6. A first spring 8 fixes the slider 5 to the vertical plate 4. A power supply module is set inside the mounting shell 2 and is used to provide energy to the induction coil 6 to heat up and perform heat treatment on the steel strip.

[0058] In use, the device body 1, together with its own power supply module, provides energy to the induction coil 6 to make it heat up. The steel strip is then passed through the induction coil 6 distributed above and below in the center by the conveying equipment for heat treatment. The conveying equipment is a conveying equipment that can transport steel strips in the prior art. Its working principle will not be described in detail here.

[0059] Pulling the vertically distributed induction coils 6 causes the slider 5 to move, separating the vertically distributed induction coils 6. This causes the push rod 7 to move accordingly. The slider 5 compresses the first spring 8, causing it to deform and generate force. As the steel belt is transported, it moves between the separated push rods 7. At this point, the induction coils 6 are released, and the slider 5, carrying the induction coils 6, returns to its original position, causing the push rod 7 to return to its original position. The push rod 7 then contacts the surface of the steel belt, and its end slides relative to the steel belt. Since the distance between the end of the push rod 7 that contacts the steel belt and the induction coil 6 is fixed, the distance between the two induction coils 6 and the surface of the steel belt is the same, allowing for uniform heating of the steel belt. Because some parts of the steel belt are not completely horizontal and are partially bent, the bent parts move to... When the protruding part of the steel strip corresponds to the push rod 7, it will squeeze the corresponding push rod 7, causing it to move further away from the steel strip along with the induction coil 6 and the slider 5. When the concave part corresponding to the protruding part of the steel strip corresponds to the push rod 7, the first spring 8 releases its force, causing the slider 5, the induction coil 6, and the push rod 7 to move closer to the steel strip. This allows the push rod 7 to maintain contact with the concave part, ensuring that the distance between the upper and lower distributed induction coils 6 and the steel strip remains consistent, thus enabling uniform heating. Throughout the process, the push rod 7 maintains contact with the upper and lower surfaces of the steel strip, allowing the position of the induction coils 6 to be automatically adjusted, ensuring that the distance between the upper and lower distributed induction coils 6 and the steel strip is consistent, thereby enabling uniform heat treatment of the steel strip.

[0060] like Figures 2 to 6 As shown, the induction coil 6 is equipped with a correction component for correcting the position of the push rod 7;

[0061] The correction assembly includes: a carrier plate 22, a bracket 11, a slide bar 13, a connecting assembly, a fixing assembly, a limiting assembly, and a second spring 14;

[0062] The carrier plate 22 is fixed on the surface of the induction coil 6, the bracket 11 is fixedly connected to the outside of the carrier plate 22, the slide rod 13 is slidably mounted on the bracket 11, the connecting assembly is used to connect the slide rod 13 to the top rod 7, the fixing assembly is used to fix the top rod 7, the limiting assembly is used to limit the position of the top rod 7 in the vertical direction, and the second spring 14 is sleeved on the outside of the slide rod 13 to drive the top rod 7 to move in the vertical direction. The top rod 7 passes through the carrier plate 22.

[0063] Due to long-term use, the push rod 7 will wear out, causing the position of the push rod 7 from the induction coil 6 to change, which will affect the uniformity of subsequent heating of the steel strip.

[0064] Therefore, after each use, the fixing component is removed from the top rod 7. At this time, the compressed second spring 14 drives the top rod 7 to move towards the limiting component. Then, one end of the top rod 7 comes into contact with the limiting component. At this time, the distance between the end of the top rod 7 that comes into contact with the limiting component and the induction coil 6 is adjusted. The distance between the ends of the top rods 7 that come into contact with the limiting component and the corresponding induction coils 6 is consistent. Then, the fixing component is reset to fix the top rod 7. This completes the correction of the position of the top rod 7, so that the distance between the top rod 7 and the induction coil 6 can be corrected. This ensures that the distance between the end of the top rod 7 and the induction coil 6 will not change due to wear during subsequent use, thus ensuring uniform heating.

[0065] like Figure 3 and Figure 5 As shown, the connecting assembly includes: a connecting rod 12 and a bolt 15;

[0066] The connecting rod 12 is fixedly connected to one end of the slide rod 13. The connecting rod 12 is inserted into the inside of the top rod 7. The bolt 15 connects the top rod 7 and the connecting rod 12. The second spring 14 is set between the connecting rod 12 and the bracket 11. The second spring 14 connects the bracket 11 and the connecting rod 12.

[0067] When the push rod 7 needs to be replaced, the connection between the push rod 7 and the connecting rod 12 is removed by bolt 15. At this time, the push rod 7 can be pulled out from the carrier plate 22, so that the push rod 7 can be replaced.

[0068] like Figure 3 As shown, the fixing assembly includes: electric push rod 16, push block 17, and clamping block 18;

[0069] The electric push rod 16 is symmetrically fixedly installed on the carrier plate 22, the push block 17 is fixedly connected to one end of the electric push rod 16, and the clamping block 18 is fixedly connected to the top of the push block 17.

[0070] Start the electric push rod 16 to shorten its telescopic end, thereby moving the push block 17 and clamping block 18 away from the top rod 7. At this time, the clamping and fixing of the top rod 7 is released, and the top rod 7 can move in the vertical direction. Conversely, extend the telescopic end of the electric push rod 16 to reset it, thereby resetting the clamping block 18 to clamp and fix the top rod 7.

[0071] The carrier plate 22 is made of ceramic fiber, which gives it good heat insulation and can provide heat insulation protection for the electric push rod 16.

[0072] like Figure 2 and Figure 6 As shown, the limiting components include: gear 19, baffle 20, teeth 21, and motor 23;

[0073] The baffle 20 is slidably mounted on the equipment body 1, the gear 19 is rotatably mounted inside the equipment body 1, the teeth 21 are equidistantly arranged on the surface of the baffle 20, the teeth 21 mesh with the gear 19, the motor 23 is fixedly connected inside the equipment body 1, and the output shaft of the motor 23 is connected to the middle of one side of the gear 19.

[0074] The motor 23 is started, causing its output shaft to rotate forward, which in turn rotates the gear 19. This causes the meshing teeth 21 to drive the baffle 20 to move closer to the push rod 7. The baffle 20 then passes between a pair of push rods 7. If the push rods 7 are new and unworn, both sides of the baffle 20 can fit against the surface of the corresponding push rod 7. If the end of the push rod 7 is worn, the baffle 20 cannot contact the end of the push rod 7. At this point, the fixation of the push rod 7 is released, and the second spring 14 releases its force, causing the connecting rod 12 and the push rod 7 to move closer to the baffle 20. Finally, the push rod 7 comes into contact with the baffle 20. The push rod 7 is then fixed, completing the adjustment of the push rod 7 so that the distance between the upper and lower distributed push rods 7 and their respective induction coils 6 is consistent.

[0075] like Figure 3 As shown, the power supply module includes: power supply 9 and power cord 10;

[0076] The power supply 9 is located inside the mounting housing 2. The power cord 10 connects the power supply 9 to the induction coil 6. A wire passage is provided on the vertical plate 4, through which the power cord 10 passes.

[0077] The induction coil 6 is powered by the power supply 9 and power cord 10 on the device body 1.

[0078] like Figure 3 As shown, the top rods 7 located above and below are symmetrically arranged, and the top rods 7 can withstand the heat generated when the induction coil 6 is heated.

[0079] like Figure 2 As shown, when the baffle 20 moves between the two opposing induction coils 6, the distance between the baffle 20 and the upper induction coil 6 is the same as the distance between the baffle 20 and the lower induction coil 6.

[0080] This ensures that the baffle 20 is centered, allowing for subsequent adjustment of the position of the top rod 7.

[0081] like Figure 3 As shown, the elastic force of the second spring 14 is less than that of the first spring 8.

[0082] When the second spring 14 releases its force and causes one end of the push rod 7 to contact the baffle 20, the second spring 14 can no longer release its force to overcome the elastic force of the first spring 8 and cause the bracket 11, the carrier plate 22, and the slider 5 to move, so that the slider 5 remains stationary, thereby keeping the induction coil 6 stationary.

[0083] like Figure 3 As shown, when the clamping block 18 abuts against the push rod 7, the friction between the clamping block 18 and the push rod 7 can fix the push rod 7.

[0084] Working Principle: During use, pulling the upper and lower distributed supports 11 causes the carrier plate 22, electric push rod 16, push block 17, clamping block 18, top rod 7, induction coil 6, and slider 5 to move, separating the upper and lower distributed induction coil 6 and top rod 7. Slider 5 compresses the first spring 8, causing it to deform and generate force, which guides the steel strip through the center of the conveyor between the upper and lower distributed induction coils 6 for heat treatment. As the steel strip is conveyed, it moves to the separated top rods 7. At this point, the supports 11 are released, and slider 5, carrying the induction coil 6, returns to its original position, causing the top rod 7 to return to its original position. The top rod 7 then contacts the surface of the steel strip. The device body 1, in conjunction with its own power supply module, provides energy to the induction coil 6, causing it to heat up. The end of the top rod 7 slides relative to the steel strip. Since the distance between the end of the top rod 7 that contacts the steel strip and the induction coil 6 is fixed, the distance between the upper and lower induction coils 6 and the surface of the steel strip is consistent, allowing for uniform heating of the steel strip. Due to the partial heating of the steel strip... It is not completely horizontal; it has a partial bend. When the bend moves to correspond with the top rod 7, the protruding part of the steel strip will squeeze the corresponding top rod 7, causing it to move further away from the steel strip, along with the clamping block 18, the push block 17, the electric push rod 16, the carrier plate 22, the induction coil 6, and the slider 5. After the concave part corresponding to the protruding part of the steel strip aligns with the top rod 7, the first spring 8 releases its force, causing the slider 5, the induction coil 6, the carrier plate 22, the electric push rod 16, the push block 17, the clamping block 18, and the top rod 7 to move closer to the steel strip. This allows the top rod 7 to maintain contact with the concave part, ensuring that the distance between the upper and lower distributed induction coils 6 and the steel strip remains consistent, thus enabling uniform heating. Throughout the process, the top rod 7 maintains contact with the upper and lower surfaces of the steel strip, allowing the position of the induction coils 6 to be automatically adjusted, ensuring that the distance between the upper and lower distributed induction coils 6 and the steel strip remains consistent, thereby enabling uniform heat treatment of the steel strip.

[0085] Due to long-term use, the push rod 7 will wear out, causing the position of the push rod 7 from the induction coil 6 to change, which will affect the uniformity of subsequent heating of the steel strip.

[0086] Therefore, after each use, the motor 23 is started, causing its output shaft to rotate clockwise, which in turn rotates the gear 19. This causes the meshing teeth 21 to drive the baffle 20 to move closer to the push rod 7. Subsequently, the baffle 20 passes between the pair of push rods 7. If the push rods 7 are new and unworn, both sides of the baffle 20 can fit against the corresponding push rod 7 surfaces. If the ends of the push rods 7 are worn, the baffle 20 cannot contact the ends of the push rods 7. The electric push rod 16 is then activated, causing its telescopic end to shorten, thereby moving the push block 17 and clamping block 18 away from the push rods 7. At this point, the clamping and fixing of the push rod 7 is released, and the second spring 14 releases its force, causing the connecting rod 12 and the push rod 7 to move towards the baffle 20. Finally, the push rod 7 comes into contact with the baffle 20, and then the electric push rod 16 is reset, so that the clamping block 18 resets to clamp and fix the push rod 7, completing the adjustment of the push rod 7. This ensures that the distance between the upper and lower distributed push rods 7 and their respective induction coils 6 is consistent, so that the distance between the end of the push rod 7 and the induction coil 6 will not change due to wear during subsequent use, thus ensuring uniform heating.

[0087] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
