Description

Technical Field

[0001] This utility model relates to the field of steel bar drying technology, specifically a drying device for heating and quenching steel bars. Background Technology

[0002] Bar heating and quenching is one of the key processes in the heat treatment of metallic materials. Its core principle is to alter the microstructure of steel through rapid cooling, thereby obtaining the desired mechanical properties. Before quenching, the surface of the steel bar must undergo rigorous drying to thoroughly remove residual moisture, oil, or coolant. If these residues are not completely removed, problems such as steam and oxide scale will occur during subsequent high-temperature heating, severely affecting the quenching quality and the steel's properties.

[0003] Traditional drying equipment typically mounts the heating element fixedly at the top of the chamber. This design causes the steel bars to pass through the drying area in a fixed posture during transport. Because the steel bars cannot adjust their posture, their tops always face the heat source, resulting in uneven heating: the top area may overheat due to direct heating, while the bottom and sides may not dry completely due to insufficient heat radiation. This uneven heating not only affects the drying effect but may also cause thermal stress deformation in the steel bars, thus affecting the quality stability of subsequent quenching processes. Therefore, a new drying device for heating and quenching steel bars is needed to address these shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing steel bars that cannot be adjusted in posture during the movement of the drying box, resulting in uneven drying.

[0005] To address the aforementioned technical problems, this application provides a drying device for heating and quenching steel bars, comprising a drying chamber. A set of conveying components is movably connected inside the drying chamber. Each conveying component includes a first conveyor and a second conveyor, which are horizontally staggered, with the second conveyor positioned above the first conveyor. Several support blocks are fixedly connected to the outer side of the first conveyor for supporting the steel bars. Several protective components are fixedly connected to the outer side of the second conveyor to prevent the steel bars from tilting. A set of symmetrical adjusting components is provided inside the drying chamber, and these adjusting components are movably connected to the steel bars. The adjusting components are respectively connected to the first and second conveyors.

[0006] In some embodiments, the transmission assembly includes rollers, sprockets, and a chain belt. The rollers are symmetrically arranged, and sprockets are fixedly connected to both ends of each roller. The chain belt is symmetrically arranged and is disposed on the outside of the two sprockets. The sprockets and the chain belt constitute a chain drive structure.

[0007] In some embodiments, the rollers are movably connected to the inside of the drying chamber via a rotating shaft, and several support blocks are fixedly connected to the outer side of the chain belt of the first conveyor.

[0008] In some embodiments, the protective component includes a connecting block, a folding spring, and a protective block. Several connecting blocks are fixedly connected to the outer side of the chain belt of the second conveyor, and a folding spring is fixedly connected inside each connecting block. The other end of the folding spring is fixedly connected to a protective block, and the protective block is movably engaged with the interior of the connecting block. The steel rod is located between the support block and the protective block.

[0009] In some embodiments, the adjustment assembly includes sprocket two, sprocket three, and chain belt two. Sprocket two and sprocket three are symmetrically arranged. Chain belt two is sleeved on the outside of sprocket two and sprocket three. Sprocket two, sprocket three, and chain belt two constitute a chain drive structure. Sprocket two and sprocket three are movably connected to the inside of the drying oven through a rotating shaft.

[0010] In some embodiments, the adjustment assembly further includes gear one and gear two, gear one is fixedly connected to the outer side of the shaft of sprocket two, gear two is fixedly connected to the end of the roller shaft of the transmission component one, and gear one and gear two mesh with each other.

[0011] In some embodiments, a timing wheel is fixedly connected to the outer side of the shaft of the second sprocket, and a timing wheel is fixedly connected to the end of the roller shaft of the second transmission component. A timing belt is sleeved on the outer side of the timing wheel and the timing wheel, and the timing wheel, the timing wheel and the timing belt constitute a belt drive structure. The timing belt is located on the outside of the drying box, and a servo motor is fixedly connected to the outside of the drying box. The output end of the servo motor is fixedly connected to the end of the roller shaft of the second transmission component.

[0012] This utility model has at least the following beneficial effects:

[0013] I. This utility model, through the setting of protective components, under the action of the upper chain belt, the protective block rotates just above the steel rod and moves synchronously with the steel rod. If the steel rod tilts up during the movement, the steel rod will hit the protective block. The protective block moves longitudinally, causing the folding spring to deform, thereby preventing the steel rod from falling off the support block. This allows the steel rod to adjust its posture during the movement of the drying box, thereby drying the bearing of the steel rod.

[0014] Second, this utility model uses an adjustment component to make the direction of the steel bar's movement opposite to the direction of the chain belt's rotation. Several actuating bars are fixedly connected to the chain belt. Because the surface of the steel bar has textured and uneven surfaces, when the actuating bars come into contact with the outer side of the moving steel bar, the steel bar rolls continuously on the support block, which continuously adjusts the posture of the steel bar. This is beneficial for the heating device at the top of the drying chamber to fully dry the surface of the steel bar. Attached Figure Description

[0020] 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.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a drying device for heating and quenching steel bars, including a drying box 1. A set of conveying components 2 is movably connected inside the drying box 1. The conveying components 2 include a first conveyor and a second conveyor, which are arranged horizontally and alternately, with the second conveyor located above the first conveyor. Several support blocks 3 are fixedly connected to the outside of the first conveyor for supporting the steel bars. Several protective parts 4 are fixedly connected to the outside of the second conveyor for preventing the steel bars from tilting. A set of symmetrical adjustment components 5 is provided inside the drying box 1, and the adjustment components 5 are movably connected to the steel bars. The adjustment components 5 are respectively connected to the first conveyor and the second conveyor.

[0022] The drying process for steel bars during heating and quenching is a crucial step in dehumidifying the surface of the steel bars before quenching. This aims to remove moisture, oil, or coolant residue, preventing problems such as steam buildup, oxide scale formation, or uneven quenching during subsequent high-temperature heating. Typically, hot air circulation, infrared radiation, or induction heating are used to uniformly heat the steel bars to 100-300°C. In this application, the surface of the steel bars is heated using a drying chamber 1, which also has a function to expel water vapor. The steel bars are placed on support blocks 3 via a feeding mechanism and then conveyed into the drying chamber 1 by a conveying assembly 2. The drying device precisely controls the temperature and is equipped with a smoke extraction system to prevent energy waste or environmental pollution, ultimately providing clean and dry steel bars for quenching and ensuring stable heat treatment quality. After drying, the steel bars are moved from the end of the drying chamber 1 to the next process step, thus constituting a complete technical solution for steel bar drying.

[0023] like Figure 1 and Figure 3 As shown, the conveyor assembly 2 includes rollers 201, sprockets 202, and a chain belt 203. The rollers 201 are symmetrically arranged, and sprockets 202 are fixedly connected to both ends of each roller 201. The chain belt 203 is symmetrically arranged and is sleeved on the outside of the two sprockets 202. The sprockets 202 and the chain belt 203 constitute a chain drive structure. The rollers 201 are movably connected to the inside of the drying chamber 1 via rotating shafts, and the chain belt 203 of the conveyor assembly 2 is... Several support blocks 3 are fixedly connected to each side. The protective component 4 includes a connecting block 401, a folding spring 402, and a protective block 403. Several connecting blocks 401 are fixedly connected to the outer side of the chain belt 203 of the second conveyor. Folding springs 402 are fixedly connected inside the connecting blocks 401. The other end of the folding spring 402 is fixedly connected to the protective block 403. The protective block 403 is movably engaged with the internal part of the connecting block 401. The steel rod is located between the support block 3 and the protective block 403.

[0024] Controlling the rotation of one of the rollers 201 enables the sprockets 202 at both ends to rotate synchronously. Under the action of the chain belt 203, the sprocket 202 at the other end of the drying chamber 1 rotates synchronously. The words "upper" and "lower" are used to distinguish between the first and second conveyor components. The lower chain belt 203 drives the support block 3 to rotate cyclically, thereby continuously moving the steel rod into the interior of the drying chamber 1. The upper chain belt 203 drives the protective block 403 to rotate cyclically. Since the upper and lower chain belts 203 are parallel and staggered, when one end of the steel rod is far enough away, under the action of the upper chain belt 203, the protective block 403 rotates to be directly above the steel rod and moves synchronously with it. If the steel rod tilts up during the movement, it will hit the protective block 403. The protective block 403 moves longitudinally, causing the folding spring 402 to deform, thereby preventing the steel rod from falling off the support block 3. This allows the steel rod to adjust its posture during the movement of the drying chamber 1, thereby drying the bearing of the steel rod.

[0025] like Figure 1 and Figure 4 As shown, the adjusting assembly 5 includes a second sprocket 501, a third sprocket 502, and a second chain belt 503. The second sprocket 501 and the third sprocket 502 are symmetrically arranged. The second chain belt 503 is sleeved on the outside of the second sprocket 501 and the third sprocket 502. The second sprocket 501, the third sprocket 502, and the second chain belt 503 constitute a chain drive structure. The second sprocket 501 and the third sprocket 502 are movably connected to the inside of the drying chamber 1 via a rotating shaft. The adjusting assembly 5 also includes a first gear 504 and a second gear 505. The first gear 504 is fixedly connected to the outside of the rotating shaft of the second sprocket 501. The roller 2 of the transmission component 1... Gear 2 505 is fixedly connected to the end of the shaft of 01, and gear 1 504 and gear 2 505 mesh with each other. Synchronous pulley 1 6 is fixedly connected to the outer side of the shaft of sprocket 2 501. Synchronous pulley 2 7 is fixedly connected to the end of the shaft of roller 201 of transmission component 2. Synchronous belt 8 is sleeved on the outer side of synchronous pulley 1 6 and synchronous pulley 2. Synchronous pulley 1 6, synchronous pulley 2 7 and synchronous belt 8 constitute a belt drive structure. Synchronous belt 8 is located on the outer side of drying box 1. Servo motor 9 is fixedly connected to the outer side of drying box 1. The output end of servo motor 9 is fixedly connected to the end of the shaft of roller 201 of transmission component 2.

[0026] The servo motor 9 is started, driving the upper roller 201 to rotate. Under the action of the upper chain belt 203, the other upper roller 201 rotates synchronously, driving the synchronous pulley 7 to rotate. Under the action of the synchronous belt 8, the sprocket 501, gear 504 and synchronous pulley 6 rotate synchronously. Since gear 504 and gear 505 mesh, the rotation direction of the lower roller 201 is opposite to that of the upper roller 201, and the rotation direction of the lower chain belt 203 is opposite to that of the chain belt 503. This makes the direction of movement of the steel rod opposite to the direction of rotation of the chain belt 503. Several actuating bars are fixedly connected to the chain belt 503. Since the surface of the steel rod is textured and uneven, when the actuating bars come into contact with the outer side of the moving steel rod, the steel rod rolls continuously on the support block 3, so that the posture of the steel rod is constantly adjusted, which is conducive to the heating device at the top of the drying chamber 1 to fully dry the surface of the steel rod.

[0027] Working Principle: In operation, the steel rod is first placed on the support block 3 via the feeding mechanism. The conveying assembly 2 then transports the steel rod into the drying chamber 1. The servo motor 9 is activated, driving the upper roller 201 to rotate. Under the action of the upper chain belt 203, the other upper roller 201 rotates synchronously, driving the synchronous pulley 7 to rotate. Under the action of the synchronous belt 8, the sprocket 501, gear 504, and synchronous pulley 6 rotate synchronously. Because gear 504 and gear 505 mesh, the rotation direction of the lower roller 201 is opposite to that of the upper roller 201. Therefore, the rotation directions of the upper and lower chain belts 203 are opposite. Since the upper and lower chain belts 203 are parallel and staggered, after one end of the steel rod is moved away from the support block, under the action of the upper chain belt 203... 403 rotates to be directly above the steel bar, and the direction of the steel bar's movement is opposite to the direction of rotation of the second chain belt 503. Several actuating bars are fixedly connected to the second chain belt 503. Because the surface of the steel bar is textured and uneven, when the actuating bars come into contact with the outer side of the moving steel bar, the steel bar rolls continuously on the support block 3, which continuously adjusts the posture of the steel bar. This helps the heating device at the top of the drying chamber 1 to fully dry the surface of the steel bar. As the steel bar moves synchronously, if the steel bar tilts up during the movement, it will hit the protective block 403. The protective block 403 moves longitudinally, causing the folding spring 402 to deform, thereby preventing the steel bar from detaching from the support block 3. Finally, the protective block 403 rolls with the upper chain belt 203 and separates from the steel bar. The support block 3 rolls with the lower chain belt 203, causing the steel bar to fall into the next process.
