Description

Technical Field

[0001] The present invention belongs to the technical field of threaded steel production equipment, and specifically relates to a high-strength threaded steel and its heat treatment device and method. Background Art

[0002] High-strength threaded steel is a straight bar of large diameter, high strength, and high dimensional accuracy with external threads rolled on the entire steel bar. The threaded steel has spiral grooves. This groove design not only enhances the grip between the steel and concrete, but also helps to disperse stress and improve the stability of the structure. The heat treatment device for threaded steel is a device used to heat-treat threaded steel, aiming to improve its service performance and meet the requirements of subsequent processing or use. Heat treatment can change the internal organizational structure of steel, eliminate various defects generated in hot working processes such as casting, forging, and welding, refine grains, eliminate segregation, reduce internal stress, and make the tissue properties more uniform.

[0003] With the rapid development of infrastructure construction such as buildings and bridges, the demand for high-strength threaded steel is increasing day by day. However, in the traditional threaded steel production process, the cutting after heat treatment often relies on manual operation, which has problems of low efficiency and high labor intensity. Especially during the cutting process, due to the large length and weight of the threaded steel, manual cutting is not only time-consuming and laborious, and cannot accurately cut the threaded steel body according to the preset length, but also the threaded steel needs to be naturally cooled after tempering treatment, and the natural cooling time is relatively long, thus increasing the heat treatment cycle. Summary of the Invention

[0004] The purpose of the present invention is: through the close cooperation among the feeding mechanism, the cooling mechanism, and the fixed-length cutting mechanism, the threaded steel body after heat treatment can be automatically conveyed to the cutting and feeding stations, and timely cooled after cutting, realizing continuous and efficient production, improving production efficiency and product quality. Through the feeding mechanism, automatic feeding of the threaded steel body is realized, and the whole process does not require manual intervention, improving production efficiency and avoiding the low efficiency and high labor intensity of the threaded steel body feeding due to relying on manual operation after heat treatment. Through the driving components in the cooling mechanism to drive multiple fans to rotate, the fans can rotate according to the heat treatment requirements of the threaded steel body, enhance air flow, and improve the cooling rate. On the premise of ensuring that no internal stress and deformation occur in the threaded steel body, the heat treatment time is effectively shortened and the production efficiency is improved. Through the fixed-length cutting mechanism, it can ensure that the cutting tool accurately cuts the threaded steel body according to the preset length, reducing material waste.

[0019] A heat treatment method for high-strength deformed steel bars includes the following steps:

[0020] Step 1: Heat treatment: Heat, gradient cool, and perform two-stage tempering on the threaded steel body through the heat treatment equipment main body on the base to complete the heat treatment of the threaded steel body;

[0021] Step 2: Fixed-length cutting: The heat-treated threaded steel body is conveyed to the guide wheel in one of the guide frames. One end of the threaded steel body pushes the limit rod to move. The limit rod rotates on the limit shaft, driving the third connecting rod. The third connecting rod pulls the moving rod to move in the moving hole, making the sliding block located above the mounting plate. Then, when the pressing rod moves downward, it presses the mounting plate, which can drive the mounting plate and the sliding block to move downward simultaneously, so that the cutting tool at the bottom of the mounting plate cuts the threaded steel body according to the preset length;

[0022] Step 3: Discharging of the threaded steel body: After the threaded steel body is cut, the second servo motor drives the rotating shaft to rotate. The rotating shaft drives each rotating part to rotate, so that the limit wheel is located above the threaded steel body. The limit wheel cooperates with the guide wheel to fix the threaded steel body. Then, start the forward and reverse motor. The forward and reverse motor drives the bidirectional threaded rod to rotate, driving the moving part to move in the rotating cylinder. As each moving part moves, cooperating with the first connecting rod, each guide frame shrinks, driving the cut threaded steel body to move downward, preventing the cut threaded steel body from still pressing against the limit rod. The limit rod, sliding block, and mounting plate return to their original positions under the elastic force of the first spring, second spring, and third spring. Finally, the first servo motor drives the driving dial to rotate, so that the cylindrical pin enters one of the radial slots, pushing the sprocket, and the sprocket drives the rotating cylinder to intermittently rotate between each support frame, so that the threaded steel body reaches the discharging position after passing through the fan. The second servo motor drives the rotating shaft to rotate in the reverse direction, making the limit wheel move away from below the guide wheel, and the threaded steel body falls to the designated position to complete the discharging;

[0023] Step 4: Cooling the threaded steel body: When the threaded steel body is on one side of the fan, the fourth servo motor drives the mounting shaft to rotate, making each first bevel gear rotate. The first bevel gear meshes with the second bevel gear, so that the second bevel gear drives the fan on each rotating shaft to rotate. On the premise of ensuring that the threaded steel body does not generate internal stress and deformation, the rotation of the fan enhances air flow and improves the cooling rate of the threaded steel body. At the same time, as the mounting shaft rotates, it can drive one of the fourth bevel gears to rotate, making one of the fourth bevel gears mesh with one of the third bevel gears, so that the connecting shaft drives the other third bevel gear to rotate. The other third bevel gear meshes with the other fourth bevel gear, making the L-shaped frame rotate. The L-shaped frame pulls the top of the second connecting rod to move, and the bottom of the second connecting rod drives the pressing rod to reciprocate, so as to facilitate the pressing rod to press the sliding block, thereby realizing the cutting of the threaded steel body.

[0024] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0025] (1) In the present invention, through the close cooperation among the blanking mechanism, the cooling mechanism and the fixed-length cutting mechanism, the heat-treated threaded steel body can be automatically transported to the cutting and blanking stations, and can be cooled in time after cutting, realizing continuous and efficient production, and improving production efficiency and product quality.

[0026] (2) In the present invention, through the blanking mechanism, automatic blanking of the threaded steel body is realized, and the whole process does not require manual intervention, improving production efficiency and avoiding the low blanking efficiency and large labor intensity of the threaded steel body caused by relying on manual operation for blanking after heat treatment.

[0027] (3) In the present invention, through the driving component in the cooling mechanism to drive a plurality of fans to rotate, the fans can rotate according to the heat treatment requirements of the threaded steel body, enhancing air flow and increasing the cooling rate. On the premise of ensuring that the threaded steel body does not generate internal stress and deformation, the heat treatment time is effectively shortened and the production efficiency is improved.

[0028] (4) In the present invention, through the fixed-length cutting mechanism, it can ensure that the cutting tool accurately cuts the threaded steel body according to the preset length, reducing material waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In this implementation scheme: The base 3 is the support foundation of the entire device, providing installation positions for other components. The heat treatment equipment main body 4 is used to heat, gradient cool, and perform two-stage tempering on the threaded steel main body 1 to improve the organizational structure of the threaded steel and enhance its strength and toughness. The heating of the threaded steel main body 1 by the heat treatment equipment main body 4 is carried out through a multi-stage ultra-audio induction coil to improve the strength and toughness of the threaded steel main body 1. Gradient cooling is carried out using a water-based quenching liquid to prevent changes in its organizational structure and reduce the risk of cracking.

[0063] In this embodiment: The limiting rod 701 is used to contact the threaded steel body 1 to trigger the cutting action. The movement of the limiting rod 701 drives the third connecting rod 710, and further causes the moving rod 712 to move in the moving hole 711, making the sliding block 715 located above the mounting plate 717. Cooperating with the pressing action of the pressing rod 708, the fixed-length cutting of the threaded steel body 1 is realized, improving the cutting accuracy and efficiency. When the threaded steel body 1 pushes the limiting rod 701 to move, the positions of the sliding block 715 and the mounting plate 717 can be accurately controlled, ensuring that the cutting tool 702 accurately cuts the threaded steel body 1 according to the preset length, reducing material waste.

[0064] During use, Step 1: Heat treatment: The ribbed steel bar body 1 is heated, gradient cooled, and double-stage tempered through the heat treatment equipment main body 4 on the base 3 to complete the heat treatment of the ribbed steel bar body 1. Step 2: Fixed-length cutting: The heat-treated ribbed steel bar body 1 is conveyed onto the guide wheel 503 in one of the guide frames 502. One end of the ribbed steel bar body 1 pushes the limit rod 701 to move. The limit rod 701 rotates on the limit shaft 709, driving the third connecting rod 710. The third connecting rod 710 pulls the moving rod 712 to move in the moving hole 711, so that the sliding block 715 is located above the mounting plate 717. Then when the pressing rod 708 moves downward, it presses the mounting plate 717, and can drive both the mounting plate 717 and the sliding block 715 to move downward at the same time, so that the cutting tool 702 at the bottom of the mounting plate 717 cuts the ribbed steel bar body 1 according to the preset length. Step 3: Discharging of the ribbed steel bar body 1: After the ribbed steel bar body 1 is cut, the second servo motor 515 drives the rotating shaft 516 to rotate. The rotating shaft 516 drives each rotating part 517 to rotate, so that the limit wheel 518 is located above the ribbed steel bar body 1. The limit wheel 518 cooperates with the guide wheel 503 to fix the ribbed steel bar body 1. Then the forward and reverse motor 511 is started. The forward and reverse motor 511 drives the bidirectional threaded rod 512 to rotate, driving the moving part 513 to move in the rotating cylinder 505. As each moving part 513 moves, in cooperation with the first connecting rod 514, each guide frame 502 contracts, driving the cut ribbed steel bar body 1 to move downward, avoiding the cut ribbed steel bar body 1 still pressing against the limit rod 701, so that the limit rod 701, the sliding block 715, and the mounting plate 717 return to their original positions under the action of the elastic forces of the first spring 713, the second spring 716, and the third spring 718. Finally, the first servo motor 506 drives the driving dial 507 to rotate, so that the cylindrical pin 508 enters one of the radial grooves 510, pushing the sprocket 509, so that the sprocket 509 drives the rotating cylinder 505 to intermittently rotate between each support frame 504, so that the ribbed steel bar body 1 reaches the discharging position after passing through the fan 601. The second servo motor 515 drives the rotating shaft 516 to rotate in the reverse direction, so that the limit wheel 518 moves away from below the guide wheel 503, and the ribbed steel bar body 1 falls to the designated position, completing the discharging. Step 4: Cooling the ribbed steel bar body 1: When the ribbed steel bar body 1 is on one side of the fan 601, the fourth servo motor 602 drives the mounting shaft 603 to rotate, so that each first bevel gear 604 rotates. The first bevel gear 604 meshes with the second bevel gear 605, so that the second bevel gear 605 drives the fan 601 on each rotating shaft 606 to rotate. On the premise of ensuring that the ribbed steel bar body 1 does not generate internal stress and deformation, the rotation of the fan 601 enhances air flow and improves the cooling rate of the ribbed steel bar body 1. At the same time, as the mounting shaft 603 rotates, it can drive one of the fourth bevel gears 705 to rotate, so that one of the fourth bevel gears 705 meshes with one of the third bevel gears 704, and the connecting shaft 703 drives the other third bevel gear 704 to rotate.Another third bevel gear 704 meshes with another fourth bevel gear 705 to rotate the L-shaped frame 706. The L-shaped frame 706 pulls the top end of the second connecting rod 707 to move, and the bottom end of the second connecting rod 707 drives the pressing rod 708 to reciprocate, so as to facilitate the pressing rod 708 to press the sliding block 715, thereby realizing the cutting of the ribbed steel body 1.

[0065] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.

A heat treatment method for high-strength deformed steel bars, characterized in that: Applying a heat treatment device for high-strength deformed steel bars as described in claim 9, the method includes the following steps: S1: Heat treatment: The deformed steel bar body (1) is heated, gradient cooled, and double-stage tempered through the heat treatment equipment main body (4) on the base (3) to complete the heat treatment of the deformed steel bar body (1). S2: Fixed-length cutting: The heat-treated threaded steel body (1) is transported to the guide wheel (503) in one of the guide frames (502), and one end of the threaded steel body (1) pushes the limit rod (701) to move. The limit rod (701) rotates on the limit shaft (709), driving the third connecting rod (710). The third connecting rod (710) pulls the moving rod (712) to move in the moving hole (711), so that the sliding block (715) is located above the mounting plate (717). Then, when the pressing rod (708) moves downward, the mounting plate (717) is pressed, which can simultaneously drive the mounting plate (717) and the sliding block (715) to move downward, so that the cutting tool (702) at the bottom of the mounting plate (717) cuts the threaded steel body (1) according to the preset length; S3: Cutting of the threaded steel body (1): After the threaded steel body (1) is cut, the second servo motor (515) drives the rotating shaft (516) to rotate, and the rotating shaft (516) drives each rotating member (517) to rotate, so that the limiting wheel (518) is located above the threaded steel body (1), and the limiting wheel (518) cooperates with the guide wheel (503) to fix the threaded steel body (1), and then the forward and reverse motor (511) is started, and the forward and reverse motor (511) drives the bidirectional threaded rod (512) to rotate, driving the moving member (513) to move in the rotating cylinder (505). As each moving member (513) moves, it cooperates with the first connecting rod (514) to make each guide frame (502) shrink, driving the threaded steel body (1) after cutting to move downward, so as to prevent the threaded steel body (1) after cutting from still pressing against the limiting wheel. The positioning rod (701) causes the limiting rod (701), the sliding block (715) and the mounting plate (717) to return to their original positions under the action of the elastic force of the first spring (713), the second spring (716) and the third spring (718). Finally, the first servo motor (506) drives the active dial (507) to rotate, causing the cylindrical pin (508) to enter one of the radial grooves (510), pushing the groove wheel (509), causing the groove wheel (509) to drive the rotating cylinder (505) to rotate intermittently between each support frame (504), so that the threaded steel body (1) reaches the unloading position after passing through the fan (601). The second servo motor (515) drives the rotating shaft (516) to rotate in the opposite direction, causing the limiting wheel (518) to move away from the bottom of the guide wheel (503), so that the threaded steel body (1) falls to the specified position, completing the unloading. S4: Cooling the ribbed steel bar body (1): When the ribbed steel bar body (1) is located on one side of the fan (601), drive the mounting shaft (603) to rotate through the fourth servo motor (602) so that each first bevel gear (604) rotates. The first bevel gear (604) meshes with the second bevel gear (605), causing the second bevel gear (605) to drive the fan (601) on each rotating shaft (606) to rotate. On the premise of ensuring that no internal stress and deformation occur in the ribbed steel bar body (1), enhance the air flow through the rotation of the fan (601) to increase the cooling rate of the ribbed steel bar body (1). At the same time, as the mounting shaft (603) rotates, it can drive one of the fourth bevel gears (705) to rotate, causing one of the fourth bevel gears (705) to mesh with one of the third bevel gears (704), enabling the connecting shaft (703) to drive the other third bevel gear (704) to rotate. The other third bevel gear (704) meshes with the other fourth bevel gear (705), causing the L-shaped frame (706) to rotate. The L-shaped frame (706) pulls the top of the second connecting rod (707) to move, and the bottom of the second connecting rod (707) drives the pressing rod (708) to reciprocate, so as to facilitate the pressing rod (708) to press the sliding block (715), thereby realizing the cutting of the ribbed steel bar body (1).
