Description

Technical Field

[0001] This utility model belongs to the technical field of heat treatment equipment, and more specifically, relates to a heat treatment device for high-strength steel bars. Background Technology

[0002] High-strength steel bars are core building materials in construction, bridges, and other engineering fields, and their performance directly affects the safety and durability of engineering structures. Heat treatment of steel bars is a crucial process for improving their overall strength, toughness, and other properties, and a high-strength steel bar heat treatment device is the core equipment for completing this process. This device typically includes multiple functional modules such as heating, quenching, and tempering. By heating, rapidly cooling, and reheating the steel bars, its internal structure is altered, thereby optimizing its performance. Throughout the heat treatment process, the clamping of the steel bars is critical. It must not only ensure the stability of the steel bars under complex conditions such as high temperature and cooling, but also ensure that the steel bars are heated and cooled uniformly to achieve the ideal heat treatment effect.

[0003] However, traditional high-strength steel bar heat treatment equipment has many drawbacks in steel bar clamping. On the one hand, traditional clamping structures often use single, fixed-size clamps or can only perform simple tightness adjustments, making it difficult to adapt to steel bars of different diameters and shapes. In actual engineering, steel bars come in various specifications, from small-diameter structural bars to large-diameter main reinforcing bars, and in various shapes such as plain round bars and ribbed bars. When processing steel bars of different specifications, operators have to frequently change clamps, which not only increases labor intensity but also leads to prolonged equipment downtime and a significant reduction in production efficiency. On the other hand, traditional clamping structures lack clamping stability. During the steel bar heat treatment process, especially in the quenching stage, the thermal stress generated by the sudden temperature change can easily cause the steel bars to shift or deform. Once the steel bars shift, it will lead to uneven heating and cooling, which will affect the consistency of performance after heat treatment, and in severe cases, may even lead to the scrapping of the steel bars, resulting in material waste and increased production costs. In addition, traditional clamping structures also have shortcomings in terms of ease of operation and maintenance. The complex clamp replacement process and the difficult-to-disassemble and maintain structural design further restrict the efficient operation of high-strength steel bar heat treatment equipment. Utility Model Content

[0004] In view of this, the present invention provides a high-strength steel bar heat treatment device, which solves the problems of traditional clamping structures being unable to adapt to steel bars of different specifications and having poor clamping stability, thereby improving the overall performance of the device.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a high-strength steel bar heat treatment device, comprising:

[0007] The fixed base is used to provide support and mounting foundation for the entire clamping structure;

[0008] Multiple movable clamping blocks are distributed above the fixed base. Each clamping block has a concave clamping surface that matches the contour of the steel bar surface. The concave clamping surface is arc-shaped or has anti-slip texture.

[0009] The linkage assembly includes multiple linkages, one end of each linkage is movably connected to a corresponding clamping block, and the other end converges at the adjustment knob through a movable node. The linkage is a bendable rod-shaped structure that can rotate in multiple directions at the movable node.

[0010] The technical advantages of the high-strength steel bar heat treatment device provided by this utility model are as follows: By setting up a combination structure of a fixed base, a movable clamping block, and a connecting rod assembly, the fixed base provides stable support, the movable clamping block can flexibly adjust its position according to the specifications of the steel bar, the concave clamping surface is adapted to the contour of the steel bar, and the anti-slip texture enhances the friction, so that steel bars of different diameters and shapes can be firmly clamped; the connecting rod assembly converts the rotation of the adjustment knob into the movement of the clamping block, realizing multi-directional adjustment, which greatly improves the applicability of the device to various types of steel bars, avoids displacement of the steel bars due to unstable clamping during the heat treatment process, and ensures the consistency and reliability of the heat treatment effect.

[0011] Based on the above technical solution, the high-strength steel bar heat treatment device of this utility model can be further improved as follows:

[0012] The fixed base is flat and has multiple guide grooves on its surface. The guide grooves are radially distributed around the installation position of the adjustment knob. The bottom of the clamping block is provided with a slider that matches the guide groove. The clamping block can slide along the direction of the guide groove through the cooperation of the slider and the guide groove.

[0013] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the radial guide groove on the surface of the fixed base cooperates with the slider at the bottom of the clamping block to provide a precise guide path for the movement of the clamping block, so that the clamping block will not deviate or get stuck during the adjustment process, ensuring the stability and accuracy of the movement of the clamping block; this structural design makes the adjustment of the clamping block smoother, further improving the accuracy and efficiency of the steel bar clamping, and can quickly adapt to the clamping needs of steel bars of different specifications.

[0014] Furthermore, the movable connection between the clamping block and the connecting rod is a hinge, and a hinge seat is provided on the side of the clamping block. One end of the connecting rod is connected to the hinge seat through a pin, so that the clamping block can rotate relative to the connecting rod within a certain angle range.

[0015] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the clamping block and the connecting rod are connected by a hinge, so that the clamping block can not only move in the horizontal direction, but also rotate within a certain angle range. This multi-degree-of-freedom connection method can better adapt to the irregular surface shape of the reinforcing bar, ensuring that the concave clamping surface of the clamping block is in full and tight contact with the surface of the reinforcing bar, thereby further enhancing the stability and reliability of clamping, and effectively preventing the reinforcing bar from deforming or loosening due to uneven local stress during heat treatment.

[0016] Furthermore, the adjustment knob is mounted on a mounting base at the center of the fixed base. The mounting base is a columnar structure with a threaded hole at its top that matches the adjustment knob. The adjustment knob is connected to the mounting base via threads. When the adjustment knob is rotated, the clamping block is moved via the connecting rod assembly.

[0017] The beneficial effects of adopting the above-mentioned improved scheme are as follows: The adjustment knob is installed on the mounting base at the center of the fixed base and the rotation adjustment is achieved through the threaded connection. This design makes the operation of the adjustment knob more labor-saving and convenient, and can accurately control the movement distance of the clamping blocks. At the same time, the central installation method ensures that each clamping block is subjected to uniform force during the adjustment process, avoiding the instability of the steel bar clamping due to uneven adjustment, and improving the adjustment accuracy and stability of the entire clamping structure.

[0018] Furthermore, the linkage assembly includes multiple primary linkages and secondary linkages. One end of the primary linkage is connected to the clamping block, and the other end is connected to the secondary linkage through an intermediate movable node. The other end of the secondary linkage is connected to the adjustment knob, thus forming a two-stage linkage structure.

[0019] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the two-stage linkage structure consisting of a primary linkage and a secondary linkage greatly increases the adjustment range of the clamping block compared to a single-stage linkage, which can adapt to the clamping needs of a wider range of specifications of steel bars; at the same time, the transmission method of the two-stage linkage can amplify the rotation of the adjustment knob, allowing the operator to achieve a larger range of movement of the clamping block with less force, improving the convenience and efficiency of adjustment, and is especially suitable for the rapid clamping of large-diameter or special-shaped steel bars.

[0020] Furthermore, the intermediate movable node includes a connecting block, and the primary connecting rod and the secondary connecting rod are movably connected to the connecting block via pins, so that the primary connecting rod and the secondary connecting rod can rotate relative to the connecting block in different planes.

[0021] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the connecting block of the intermediate movable node is hinged to the first-level and second-level connecting rods through the pin, so that the first-level and second-level connecting rods can rotate in different planes. This flexible connection method further enhances the degree of freedom and adaptability of the connecting rod assembly; when adjusting the position of the clamping block, it can better meet the clamping requirements of complex-shaped steel bars, ensure that each connecting rod does not interfere with each other during the movement, and ensure the smooth operation and stable clamping effect of the entire clamping structure.

[0022] Furthermore, an elastic buffer layer is provided on the concave clamping surface of the clamping block, and the elastic buffer layer is made of rubber or silicone.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the elastic buffer layer on the concave clamping surface of the clamping block can play a buffering role when clamping the reinforcing bar, avoiding scratches, indentations and other damage to the surface of the reinforcing bar caused by the clamping block, and protecting the surface quality of the reinforcing bar; at the same time, the elastic buffer layer can fill the tiny gap between the clamping block and the reinforcing bar, further enhancing the stability of clamping, preventing the reinforcing bar from shifting due to vibration and other factors during heat treatment, and ensuring that the quality of the reinforcing bar after heat treatment meets the requirements.

[0024] Furthermore, the operating end of the adjustment knob is provided with anti-slip texture or anti-slip sleeve, wherein the anti-slip texture is an annular groove or a protrusion, and the anti-slip sleeve is made of rubber.

[0025] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the anti-slip texture or anti-slip sleeve on the operating end of the adjustment knob increases the friction between the operator's hand and the adjustment knob, making it easier and more stable for the operator to turn the adjustment knob, and less prone to slipping. Especially when the operator's hands are oily or sweaty, it can still ensure accurate and convenient operation. This design improves the safety and comfort of operation, reduces the difficulty of operation, and improves work efficiency.

[0026] Furthermore, the bottom of the fixed base is provided with mounting holes or mounting bolts for fixing the entire clamping structure onto the workbench of the high-strength steel heat treatment device. The mounting holes are circular through holes, and the mounting bolts are used in conjunction with threaded holes on the surface of the workbench.

[0027] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design of the mounting holes or mounting bolts at the bottom of the fixed base makes it easy to firmly install the entire clamping structure on the workbench of the high-strength steel bar heat treatment device, ensuring that the clamping structure will not shake or shift during the steel bar heat treatment process, providing a reliable foundation for the stable clamping and heat treatment of the steel bar; at the same time, this installation method is easy to disassemble and maintain. When it is necessary to inspect or replace parts of the clamping structure, it can be quickly disassembled, improving the convenience of equipment maintenance.

[0028] Furthermore, the clamping block is made of high-strength metal material, such as alloy steel or stainless steel.

[0029] The surface of the clamping block is hardened to improve its wear resistance and service life. The hardening treatment method is quenching or carburizing.

[0030] The clamping blocks are made of high-strength metal and have undergone hardening treatment, which significantly improves the wear resistance and hardness of the clamping blocks, extends their service life, reduces the frequency of replacement due to wear, and lowers the maintenance cost of the equipment. At the same time, the high-strength and high-hardness clamping blocks can withstand greater clamping forces, ensuring stable and reliable clamping performance during long-term, high-intensity steel heat treatment, thus guaranteeing the quality and efficiency of steel heat treatment.

[0031] Compared with the prior art, the beneficial effects of the high-strength steel bar heat treatment device provided by this utility model are:

[0032] The multi-directional adjustable rebar clamping structure proposed in this invention significantly improves the performance of high-strength rebar heat treatment equipment from multiple dimensions through innovative design of component structures. In terms of applicability, the coordinated design of multiple movable clamping blocks, connecting rod assemblies, and adjustment knobs allows the clamping structure to quickly and accurately adapt to rebars of different diameters and shapes. Whether it's small-diameter fine rebar, large-diameter heavy rebar, or special rebar with complex rib patterns on the surface, the clamping blocks can be flexibly adjusted in position and angle by rotating the adjustment knob to achieve stable clamping, effectively reducing downtime caused by changing clamps and significantly improving production efficiency.

[0033] Regarding clamping stability, the structural design of this utility model fully considers the stress characteristics of the reinforcing bars during heat treatment. The hinged connection between the clamping block and the connecting rod, combined with the precise guidance of the guide groove and the slider, allows the clamping block to move horizontally and rotate within a certain angle range. This ensures that the concave clamping surface of the clamping block is fully and tightly fitted to the surface of the reinforcing bar. Even in processes with high thermal stress, such as quenching, it can effectively prevent the reinforcing bar from shifting or deforming, ensuring the positional stability of the reinforcing bar during heat treatment, thereby improving the consistency and reliability of the reinforcing bar's performance after heat treatment.

[0034] In terms of ease of operation and maintainability, the centrally mounted adjustment knob and anti-slip structure allow operators to easily and accurately control the movement of the clamping blocks. The mounting holes or bolts on the bottom of the fixed base facilitate the installation and disassembly of the clamping structure. The clamping blocks are made of high-strength metal and have undergone hardening treatment, significantly extending their service life and reducing maintenance frequency and costs. These design features make the entire clamping structure more convenient and efficient in practical applications, reducing the labor intensity of operators and improving the overall value of the equipment.

[0039] 10. Fixed base; 11. Guide groove; 20. Movable clamping block; 21. Slider; 30. Linkage assembly; 31. Adjustment knob; 32. Primary link; 33. Secondary link; 34. Intermediate movable node. Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0041] like Figure 1 , Figure 2 The image shown is a first embodiment of a high-strength steel bar heat treatment device provided by this utility model. In this embodiment, it includes:

[0042] The fixed base 10 is used to provide support and mounting foundation for the entire clamping structure;

[0043] Multiple movable clamping blocks 20 are distributed above the fixed base 10. The clamping blocks have concave clamping surfaces that are adapted to the surface contour of the reinforcing bars. The concave clamping surfaces are arc-shaped or have anti-slip textures.

[0044] The linkage assembly 30 has one end of each link movably connected to the corresponding clamping block, and the other end converges at the adjustment knob 31 through a movable node. The link is a bendable rod-shaped structure that can rotate in multiple directions at the movable node.

[0045] The steel bar to be heat-treated is placed between multiple movable clamping blocks 20. According to the diameter and shape of the steel bar, the adjustment knob is turned, and the clamping blocks are moved through the connecting rod assembly 30 until the concave clamping surface of the clamping block is tightly attached to the surface of the steel bar, thus completing the initial clamping of the steel bar.

[0046] In the above technical solution, the fixed base 10 is flat and has multiple guide grooves 11 on its surface. The guide grooves 11 are radially distributed with the installation position of the adjustment knob 31 as the center. The bottom of the clamping block is provided with a slider 21 that matches the guide groove 11. The clamping block can slide along the direction of the guide groove 11 through the cooperation of the slider 21 and the guide groove 11.

[0047] When the adjustment knob is turned, the slider at the bottom of the clamp will slide smoothly along the guide groove. The operator can observe the fit between the clamp and the rebar and continuously adjust the adjustment knob until the rebar is firmly clamped.

[0048] Furthermore, in the above technical solution, the movable connection between the clamping block and the connecting rod is a hinge. A hinge seat is provided on the side of the clamping block, and one end of the connecting rod is connected to the hinge seat through a pin, so that the clamping block can rotate relative to the connecting rod within a certain angle range.

[0049] During the process of adjusting the position of the clamping block through the slider and guide groove, due to the hinge structure, the clamping block will automatically adjust the angle according to the shape of the steel bar surface. The operator only needs to continuously rotate the adjustment knob until the clamping block is completely in contact with the steel bar surface and achieves a stable clamping state.

[0050] Furthermore, in the above technical solution, the adjustment knob 31 is installed on the mounting base at the center of the fixed base 10. The mounting base is a columnar structure with a threaded hole at its top that matches the adjustment knob 31. The adjustment knob 31 is connected to the mounting base by threads. When the adjustment knob 31 is rotated, the clamping block is moved by the connecting rod assembly 30.

[0051] The operator holds the adjustment knob and turns it clockwise or counterclockwise. Because the adjustment knob is threaded with the mounting base, it will drive the connecting rod assembly to move, thereby controlling the movement of the clamping block. During the adjustment process, the adjustment knob can be gradually fine-tuned according to the clamping condition of the steel bar until the ideal clamping effect is achieved.

[0052] Furthermore, in the above technical solution, the linkage assembly 30 includes multiple primary linkages 32 and secondary linkages 33. One end of the primary linkage 32 is connected to the clamping block, and the other end is connected to the secondary linkage 33 through the intermediate movable node 34. The other end of the secondary linkage 33 is connected to the adjustment knob 31, thus forming a two-stage linkage structure.

[0053] For large-diameter or specially shaped steel bars, first place the steel bar in the middle of the clamping block, then turn the adjustment knob. The rotation of the adjustment knob is transmitted to the first-level linkage through the second-level linkage, which in turn drives the clamping block to move. Due to the amplification effect of the two-level linkage structure, the operator only needs to turn the adjustment knob slightly to make the clamping block quickly approach the steel bar and finally achieve a stable clamping.

[0054] Furthermore, in the above technical solution, the intermediate movable node 34 includes a connecting block, and the first-level connecting rod 32 and the second-level connecting rod 33 are movably connected to the connecting block through pins, so that the first-level connecting rod 32 and the second-level connecting rod 33 can rotate relative to the connecting block in different planes.

[0055] When encountering steel bars with complex shapes, the primary and secondary connecting rods will rotate freely in different planes and adjust their angles through the connecting block of the intermediate movable node during the rotation of the adjustment knob to adapt to the special shape of the steel bar. The operator continues to adjust until the clamping block fits tightly against the steel bar, thus completing a stable clamping.

[0056] Furthermore, in the above technical solution, an elastic buffer layer is provided on the concave clamping surface of the clamping block, and the elastic buffer layer is made of rubber or silicone.

[0057] After the clamping block completes the adjustment and fitting of the rebar, the elastic buffer layer will automatically make close contact with the surface of the rebar, filling the gap with its own elastic deformation, without the need for additional operation; the operator can confirm that the elastic buffer layer has played a stable clamping and protective role by observing and simply shaking the rebar.

[0058] Furthermore, in the above technical solution, the operating end of the adjustment knob 31 is provided with anti-slip texture or anti-slip sleeve. The anti-slip texture is an annular groove or a protrusion, and the anti-slip sleeve is made of rubber.

[0059] Furthermore, in the above technical solution, the bottom of the fixed base 10 is provided with mounting holes or mounting bolts for fixing the entire clamping structure to the workbench of the high-strength steel heat treatment device. The mounting holes are circular through holes, and the mounting bolts are used in conjunction with the threaded holes on the surface of the workbench.

[0060] Furthermore, in the above technical solution, the clamping block is made of high-strength metal material, such as alloy steel or stainless steel.

[0061] When the operator rotates the adjustment knob, the knob is threadedly connected to the threaded hole at the top of the central column-shaped mounting base. Based on the principle of threaded transmission, the knob's rotational motion is converted into linear motion along the thread axis, i.e., up and down movement. As the adjustment knob moves up and down, the connected secondary linkage experiences a pushing and pulling force. Because the secondary linkage and the primary linkage are hinged by a pin through a connecting block at the intermediate movable node, the movement of the secondary linkage is transmitted to the primary linkage via the connecting block, causing the primary linkage to also swing or move accordingly. The other end of the primary linkage is connected to the hinged seat on the side of the clamping block via a pin. The movement of the primary linkage ultimately drives the slider at the bottom of the clamping block to slide along the guide groove on the surface of the fixed base. Simultaneously, the clamping block can adjust its angle according to the shape of the reinforcing bar under the action of the hinged structure, thereby achieving clamping and adjustment of reinforcing bars of different specifications.

[0062] Specifically, the principle of this utility model is as follows:

[0063] The core technology of this multi-directional adjustable rebar clamping structure lies in its ingenious mechanical structure design, which enables flexible and stable clamping of rebar. The fixed base serves as the supporting foundation for the entire structure, providing a stable installation platform for other components. Its radially distributed guide grooves, in conjunction with the slider at the bottom of the clamping block, provide precise guiding constraints for the movement of the clamping block, ensuring that it slides smoothly along a predetermined trajectory during adjustment and preventing deviation or jamming.

[0064] Multiple movable clamping blocks are key components for clamping rebars. They have concave clamping surfaces that conform to the contours of the rebar surface, allowing them to fit tightly against the rebar surface, increasing the contact area and improving friction. The clamping blocks are connected to the connecting rods by a hinge, which gives the clamping blocks multi-degree-of-freedom motion characteristics. This allows them to move not only horizontally but also rotate within a certain angle range according to the shape of the rebar surface, thus better adapting to the irregular shape of the rebar and ensuring the tightness and stability of the clamping.

[0065] The linkage assembly, as a force transmission and conversion mechanism, plays a crucial role in the adjustment process. The two-stage linkage structure, consisting of a primary and a secondary linkage, converts the rotation of the adjustment knob into linear movement and angular adjustment of the clamping block. The adjustment knob is mounted on a mounting base at the center of the fixed base, achieving rotational adjustment via a threaded connection. When the operator rotates the adjustment knob, the rotation is converted into axial displacement through threaded transmission, thereby driving the linkage assembly. The two-stage linkage structure not only increases the adjustment range of the clamping block but also amplifies the rotation of the adjustment knob, allowing the operator to achieve a larger range of clamping block movement with less force, thus improving the convenience and efficiency of adjustment.
