In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.
[0026] The following combination Figures 1-4The various embodiments of the present invention are described. It should be noted that the straightened object can be a steel bar or other objects with a certain degree of ductility. For ease of description, the following embodiments are all described using steel bars as the straightened object.
[0027] Figure 1 The structural diagram of the straightener provided by the embodiment of the utility model is illustrated. Figure 2 The overall cross-sectional view of the straightener provided by the embodiment of the utility model is illustrated. Figure 1 and Figure 2 The present invention provides a straightener comprising a support assembly 100, a conveyor assembly 200, a heating assembly 300, a channel 400, and a cooling assembly 500. The heating assembly 300 is provided on the support assembly 100 and is used to heat the steel bar. There are at least two conveyor assemblies 200, each of which is used to drive the steel bar to move. When there are two conveyor assemblies 200, the two conveyor assemblies 200 are provided on the support assembly 100 and are located at both ends of the heating assembly 300. If there are more than two conveyor assemblies 200, it is necessary to ensure that a conveyor assemblies 200 are provided on both sides of the heating assembly 300 when distributing the conveyor assemblies 200. This ensures that the steel bar is subjected to force on both sides of the heating assembly 300, thereby ensuring that the steel bar can pass smoothly through the heating assembly 300. The cooling assembly 500 is provided on the support assembly 100 and is located at the end of the conveyor assemblies 200 away from the heating assembly 300, and is used to cool the steel bar. The channel 400 runs through the conveyor assemblies 200, the heating assembly 300, and the cooling assembly 500 and is used to move the steel bar.
[0028] In the above structure, the transmission component 200 provides tension to drive the steel bar to move, and the heating component 300 can heat the steel bar to a certain softening temperature, which is convenient for the subsequent straightening operation. The cooling component 500 quickly cools the heated and straightened steel bar to fix its shape and prevent deformation caused by temperature rise. The channel 400 runs through the transmission component 200, the heating component 300 and the cooling component 500, thereby providing a smooth movement path for the steel bar. It ensures that the steel bar can move along the predetermined path, enter from one end, undergo heating, straightening and cooling, and finally exit from the other end.
[0029] This embodiment achieves dual-sided drive of the rebar by providing a transmission assembly 200 on both sides of the heating assembly 300. This design not only ensures the stability of the rebar during the heating process, but also, through the dual-sided tension, enables the rebar to move forward continuously and stably in its softened state, thereby resolving the problem of poor straightening results caused by a lack of tension in traditional straighteners. Secondly, the continuous drive of the transmission assembly 200 allows the rebar to maintain a certain movement speed throughout the straightening process, avoiding problems such as overheating or insufficient straightening due to stagnant rebar.
[0030] Figure 3 It is a cross-sectional view of the transmission assembly of the straightener provided by the utility model.
[0031] Reference Figure 3 In some embodiments of the present invention, the transmission assembly 200 includes a transmission housing 210, an active transmission component 220, and a passive transmission component 230. The transmission housing 210 has a first cavity therein; the active transmission component 220 is disposed within the first cavity; and the passive transmission component 230 is disposed within the first cavity and spaced apart from the active transmission component 220. The active transmission component 220 and the passive transmission component 230 are respectively located on either side of the channel 400.
[0032] Specifically, through holes are also provided on the left and right sides of the transmission box 210, which constitute a part of the channel 400, and the two through holes are located on the same straight line. It should be noted that the gap between the active transmission component 220 and the passive transmission component 230 needs to match the diameter of the steel bar so that the steel bar can be transmitted under the clamping between the two. When the steel bar is located between the active transmission component 220 and the passive transmission component 230, the steel bar is clamped between the two, and the active transmission component 220 can drive the steel bar to rotate under the action of friction by rotating. Correspondingly, the passive transmission component 230 can also cooperate with the rotation of the active transmission component 220 by rotating.
[0033] In this embodiment, upon activation, the active transmission component 220 generates a forward driving force, propelling the rebar within the channel 400. Simultaneously, the passive transmission component 230, through its design (e.g., rollers, slide rails, etc.), engages the rebar, providing the necessary support and guidance, ensuring smooth movement along the intended path. The coordinated operation of the active and passive transmission components 220, 230 provides better support and guidance for the rebar during movement, avoiding issues such as poor straightening results or rebar deviation caused by uneven force on one side, thereby enhancing the stability of the straightening process.
[0034] Reference Figure 3In some embodiments of the present invention, the active transmission component 220 includes a driving wheel frame 221, a driving wheel 222, and a driving wheel motor 223. The driving wheel frame 221 is fixed to the bottom wall of the first cavity; the driving wheel 222 is rotatably mounted on the driving wheel frame 221 and has a recessed portion for retaining the steel bars; the driving wheel motor 223 is fixed to the driving wheel frame 221 and connected to the driving wheel 222 to drive the driving wheel 222 to rotate.
[0035] In the above structure, the driving wheel frame 221 is firmly fixed on the bottom wall of the first cavity, serving as the basis for supporting the driving wheel 222 and the driving wheel motor 223. Ensure that the driving wheel 222 and the driving wheel motor 223 can work stably without shaking or deflection. The driving wheel 222 is rotatably mounted on the driving wheel frame 221 and can rotate freely. The driving wheel motor 223 serves as the power source of the driving wheel 222, driving the driving wheel 222 to rotate. Through rotational motion, the driving wheel 222 provides forward driving force for the steel bar, enabling it to move stably in the channel. A recessed portion is provided on the driving wheel 222. When the steel bar enters the channel, it will be accurately positioned and clamped by the recessed portion, which helps to reduce the sliding or deflection of the steel bar during movement and improve the straightening accuracy and stability.
[0036] Reference Figure 3 In some embodiments of the present invention, the driven transmission component 230 includes a driven wheel frame 231, a driven wheel 232, and a sliding member 233. The driven wheel frame 231 is disposed on the top wall of the first cavity; the driven wheel 232 is slidably mounted on the driven wheel frame 231 via the sliding member 233; and a spring 234 is disposed between the sliding member 233 and the driven wheel frame 231 to adjust the distance between the driven wheel 232 and the driving wheel 222.
[0037] In the above structure, the driven wheel frame 231 is located on the top wall of the first cavity, providing a stable support platform for the driven wheel 232 and its sliding member 233. The driven wheel 232 is slidably mounted on the driven wheel frame 231 via the sliding member 233, meaning that the driven wheel 232 can move up and down along the sliding member 233 within a certain range. This design allows the driven wheel 232 to adjust its position, particularly its distance from the driving wheel, according to actual needs. A spring 234 is installed between the sliding member 233 and the driven wheel frame 231. Its primary function is to adjust the distance between the driven wheel 232 and the driving wheel. When subjected to external forces (such as the straightening force of steel bars), the spring 234 deforms, thereby changing the position of the driven wheel 232 to adapt to different working conditions. When the external force disappears, the spring 234 returns to its original shape, driving the driven wheel 232 back to its initial position, ready for the next operation.
[0038] In this embodiment, through the adjustment of spring 234, the driven transmission component 230 can automatically adapt to the needs of straightening rebars of varying diameters and lengths. When handling rebars of larger diameters, the compression of spring 234 increases the distance between the driven wheel 232 and the driving wheel, ensuring smooth passage of the rebar; and vice versa. The design of the sliding member 233 and spring 234 ensures that the driven wheel 232 remains relatively stable during movement, minimizing the impact of wobbling or drifting on straightening accuracy.
[0039] Reference Figure 2 In some embodiments of the present invention, the heating assembly 300 includes a heating box 310 and a heating wire 320 . The heating box 310 has a second cavity inside; the heating wire 320 is disposed inside the second cavity and outside the channel 400 .
[0040] It is understood that the steel bars will pass through the heating box 310 during the straightening process, and the heating wires 320 are arranged inside the heating box 310. To ensure smooth transportation of the steel bars, the heating wires 320 need to be arranged away from the steel bar transmission path. They can be arranged on the periphery or on both sides of the steel bar transmission path to heat the steel bars and soften them.
[0041] Figure 4 The schematic structural diagram of the cooling pipe of the straightener provided by the embodiment of the utility model is illustrated.
[0042] Reference Figure 2 and Figure 4 In some embodiments of the present invention, the cooling assembly 500 includes a cooling box 510, a cooling pipe 520, and a fan 530. The cooling box 510 has a third cavity inside; the cooling pipe 520 is disposed inside the third cavity; and the fan 530 is disposed in the cooling box 510 to transport the cold air around the cooling pipe 520 to the steel bars.
[0043] It is understood that by filling the cooling pipe 520 with a refrigerant, which can be cold water or condensate, etc., the refrigerant generates cold air, which is then blown onto the steel bars by the fan 530, thereby cooling the steel bars. Of course, a refrigerant pump 570 is also provided, and the inlet and outlet of the refrigerant pump 570 are respectively connected to the two ports of the cooling pipe 520 to circulate the refrigerant within the cooling pipe 520.
[0044] Reference Figure 2In some embodiments of the present invention, an air outlet 550 and an air inlet 540 are respectively provided on the front and rear walls of the cooling box 510. A fan 530 is located at the air inlet 540, and a filter 560 is provided at the air outlet 550. The provision of the air outlet 550 and the air inlet 540 allows for air circulation within the cooling box 510, facilitating cooling of the steel bars. The provision of the filter 560 prevents debris from entering the interior of the cavity. In some possible embodiments, a filter 560 may also be provided at the air inlet 540.
[0045] Reference Figure 2 In some embodiments of the present invention, a guide assembly 600 is further included. The guide assembly 600 is arranged at one end of the cooling assembly 500 away from the conveying assembly 200; the guide assembly 600 includes a guide frame 610 and at least two guide components 620. The guide frame 610 is arranged on the support assembly 100; the two guide components 620 are arranged at intervals and are located on both sides of the extension line of the support assembly 100, and the distance between the two guide components 620 is suitable for adjustment. The guide frame 610 includes a frame body 611 and at least two slides 612. The frame body 611 is arranged along the length direction of the support assembly 100; the two slides 612 are arranged at intervals along the length direction of the frame body 611, and the slides 612 are used to guide the guide components 620. The guide component 620 includes a threaded rod 621, an adjustment member 622 and a guide wheel 623. The adjusting member 622 is slidably disposed on the slideway 612 ; the threaded rod 621 penetrates the frame body 611 and is threadedly connected to the adjusting member 622 ; the guide wheel 623 is disposed at one end of the adjusting member 622 away from the threaded rod 621 .
[0046] Specifically, after the steel bar is stretched, it can be kept at a certain level under the guidance of the two guide wheels 623, thereby avoiding the bending of the steel bar due to insufficient support points. At the same time, the distance between the two guide wheels 623 can also be adjusted, so that it is suitable for steel bars of different diameters. When the distance between the two guide wheels 623 needs to be adjusted, it is only necessary to rotate the threaded rod 621. Because the threaded rod 621 is threadedly connected to the adjustment member 622, and the adjustment member 622 is slidably connected to the slide 612, the rotation of the threaded rod 621 will drive the adjustment member 622 to move, thereby driving the guide wheel 623 to move, thereby adjusting the distance between the two guide wheels 623.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
