Description

Technical Field

[0001] This invention relates to the field of straightening machine technology, specifically to an integrated machine for straightening and automatically binding steel wires for precast slab skeletons. Background Technology

[0002] Wire straightening machines are commonly used equipment in the metal wire processing industry, widely applied in construction, metal product processing, and other sectors. They are used to straighten coiled wires with initial bending stress to meet straightness requirements. The straightening rollers are the core actuators of the wire straightening machine. Through multiple forward and reverse bending operations using two rows of rollers, the residual deflection of the wire is reduced to within industry standard requirements.

[0003] During the use of the straightening machine, operators often need to adjust the gap between the straightening rollers according to the diameter of the steel wire to be processed. At the same time, since the steel wire still has initial bending stress when it enters the straightening roller group, the wear of each straightening roller often varies in actual use, with the wear rate in the middle section usually being faster than that at the ends. Therefore, it is also necessary to independently compensate for the position of each straightening roller.

[0004] Most existing straightening machines use a step-by-step adjustment method, requiring operators to manually adjust each straightening roller individually to achieve the overall gap adjustment. Some existing straightening machines use an adjustment mechanism mounted on the base to raise and lower the straightening mechanism, thereby adjusting the distance between the straightening roller and the drive roller. When changing to steel wire of different diameters, operators need to adjust the position of each straightening roller individually, which is cumbersome, time-consuming, and severely impacts the efficiency of equipment changeover.

[0005] While some existing straightening equipment can achieve synchronous adjustment of multiple rollers, overall adjustment and independent adjustment of single rollers often require two separate transmission mechanisms. For example, (authorization announcement number CN216176157U) a steel bar straightening mechanism for construction engineering uses a first servo motor and a worm gear jack to drive the angle-adjusting rack to achieve synchronous adjustment of the angle of a row of straightening rollers, while a second servo motor drives the lead screw to rotate to achieve independent adjustment of the height of a single straightening roller. Overall adjustment and single roller adjustment rely on two separate drive systems and transmission chains, which not only result in complex structures and a large number of parts, but also lack organic linkage between the two mechanisms, making switching operations cumbersome. Summary of the Invention

[0006] To address the aforementioned problems in the existing technology, this invention provides an integrated machine for straightening and automatically binding steel wires for precast slab skeletons, which has the advantages of achieving both high-efficiency overall adjustment and high-precision independent adjustment of individual rollers through a simplified transmission mechanism.

An adjustment drive plate is movably disposed on the side of the adjustment fixing plate. Both the roller connecting plate and the adjustment fixing plate are fixedly mounted on the main straightening inner shell. The straightening roller is slidably disposed on the roller connecting plate via a guide rod and a threaded roller shaft. The guide rod is used to limit the angle between the straightening roller and the roller connecting plate. An adjustment bushing is threadedly connected to the outer circumference of the threaded roller shaft. The outer circumference of the adjustment bushing is provided with teeth. The adjustment drive plate drives the adjustment bushing to rotate to adjust the position of the straightening roller.

[0008] Preferably, each of the roller connecting plates and straightening rollers is a group, and several groups are provided in total. The straightening rollers on the upper and lower sides are arranged in an alternating manner and in an S-shape.

[0009] Preferably, the side end face of the adjusting fixed plate is provided with a sliding guide structure, the adjusting drive plate slides within the sliding guide structure, the adjusting drive plate is provided with at least two limiting holes, and the sliding guide structure is provided with a locking pin that matches the limiting holes, for fixing the adjusting drive plate on the sliding guide structure.

[0010] Preferably, the adjustment drive plate is provided with an adjustment mechanism corresponding to the number of straightening rollers; The adjustment mechanism includes an adjustment gear plate, an adjustment lead screw, and an adjustment worm gear. The adjustment gear plate slides within the adjustment drive plate and meshes with the adjustment bushing. The inner side of the adjustment gear plate is threadedly engaged with the adjustment lead screw.

[0011] Preferably, the adjusting toothed plate is T-shaped, with its long side protruding outwards and the protruding side having teeth that match the adjusting bushing. The inner side of the adjusting toothed plate is the short side, and the sidewall of the short side has threaded teeth that match the adjusting lead screw.

[0012] Preferably, both the adjusting lead screw and the adjusting worm rotate within the adjusting drive plate. One end of the adjusting lead screw is provided with a worm wheel, and the adjusting worm cooperates with this worm wheel. The adjusting worm extends to the outer part of the adjusting drive plate, and the straightening roller is individually adjusted by driving the adjusting worm with a tool.

[0013] Preferably, the pre-straightening roller group includes a vertical straightening roller group and a horizontal straightening roller group, wherein the vertical straightening roller group is a combination of at least two double-row small rollers perpendicular to the straightening base, and the horizontal straightening roller group is a combination of at least two double-row small rollers parallel to the straightening base, and the straightening channels of the vertical straightening roller group and the horizontal straightening roller group are arranged coaxially.

[0014] Preferably, the traction mechanism includes a traction wheel and a traction motor, wherein the traction wheel and the traction motor are connected by a belt for traction of the workpiece and providing tension.

[0015] Preferably, the cutting mechanism includes a cutting hydraulic cylinder, on which a cutting blade is provided for cutting the workpiece.

[0016] Preferably, the straightening base is further provided with a control panel and a guide distance measuring sleeve.

[0017] Compared with the prior art, the present invention provides an integrated machine for straightening and automatically binding steel wires for precast slab skeletons, which has the following beneficial effects: 1. This precast slab frame uses a wire straightening and automatic binding integrated machine. Through the cooperation of a single mechanism and a set of transmission chains, including adjusting bushings, adjusting drive plates, and adjusting toothed plates, it achieves two modes of adjustment: overall adjustment and individual adjustment. In overall adjustment mode, the double-threaded self-locking structure of the adjusting screw and adjusting worm locks the adjusting toothed plate onto the adjusting drive plate. Operators do not need tools or electricity; they can drive all straightening rollers to rise and fall synchronously simply by manually pulling the adjusting drive plate, eliminating the need for tool operation and shortening the changeover and debugging time. In individual adjustment mode, rotating a single adjusting worm with a tool drives the independent rise and fall of a single straightening roller, compensating for uneven gaps caused by local wear. This avoids the loss of precision caused by replacing the entire set of straightening rollers or overall adjustment due to local wear, extends the service life of the straightening rollers, and reduces maintenance costs.

[0018] 2. This precast slab skeleton steel wire straightening and automatic binding integrated machine, by setting up a pre-straightening roller group, first completes the preliminary straightening of the steel wire in the vertical and horizontal directions, eliminating the original large curvature bending deformation of the steel wire in advance. This can reduce the impact of large curvature bending on the straightening rollers in the main straightening mechanism, reduce abnormal wear of the straightening rollers, extend the service life of the equipment, and also homogenize the internal stress of the steel wire in advance, so as to reduce the processing pressure of the subsequent main straightening process, avoid the problems of rapid wear of the main straightening components and unstable straightening effect, and further improve the straightness compliance rate of the finished steel wire.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1-8 As shown, a precast slab frame steel wire straightening and automatic binding integrated machine includes a straightening base 10 and a binding rack 70. The straightening base 10 is provided with a pre-straightening roller group, a main straightening mechanism, a traction mechanism and a cutting mechanism. The main straightening mechanism is installed in the middle of the straightening base 10, between the pre-straightening roller group and the traction mechanism. The pre-straightening roller group includes a vertical straightening roller group 20 and a horizontal straightening roller group 21. The vertical straightening roller group 20 is a combination of at least two double-row small rollers that are perpendicular to the straightening base 10. The horizontal straightening roller group 21 is a combination of at least two double-row small rollers that are parallel to the straightening base 10. The middle parts of the vertical straightening roller group 20 and the horizontal straightening roller group 21 are on the same center line.

[0023] The main straightening mechanism includes a main straightening outer shell 30 and a main straightening inner shell 31. Adjustment components are provided on the upper and lower sides of the main straightening inner shell 31. Each adjustment component includes an adjustment fixing plate 32, a roller connecting plate 33, and a straightening roller 34. An adjustment drive plate 321 is movably mounted on the side of the adjustment fixing plate 32. Both the roller connecting plate 33 and the adjustment fixing plate 32 are fixedly mounted on the main straightening inner shell 31. The straightening roller 34 is slidably mounted on the roller connecting plate 33 via a guide rod 341 and a threaded roller shaft 342. The guide rod 341 is used to limit the angle between the straightening roller 34 and the roller connecting plate 33. To ensure that the straightening roller 34 is inclined against the steel wire, and to restrict the relative rotation between the straightening roller 34 and the roller connecting plate 33, an adjusting bushing 343 is threadedly connected to the outer circumference of the threaded roller shaft 342. The adjusting bushing 343 has teeth on its outer circumference. The adjusting drive plate 321 drives the adjusting bushing 343 to rotate to adjust the position of the straightening roller 34. During the journey, the steel wire needs to be bent and deformed repeatedly in both directions along the arrangement of the straightening roller 34, which can gradually release the residual stress generated inside the steel wire due to rolling, gradually eliminate the initial bending curvature, and finally obtain a straight product that meets the precision requirements.

[0024] Each roller connecting plate 33 and straightening roller 34 form a group, and several groups are set up in total. The straightening rollers 34 on the upper and lower sides are arranged in an alternating S-shape. During the straightening process, the steel wire passes through the S-shaped path formed by the alternating straightening rollers 34. The straightening rollers 34 at different positions apply squeezing and bending forces to the steel wire from multiple directions, gradually eliminating the original bending deformation of the steel wire and gradually straightening the steel wire to a straight state.

[0025] The side end face of the adjusting fixed plate 32 is provided with a sliding guide structure 322. The adjusting drive plate 321 slides within the sliding guide structure 322. The adjusting drive plate 321 is provided with at least two limiting holes 324. A locking pin 323 matching the limiting holes 324 is provided at the sliding guide structure 322 to fix the adjusting drive plate 321 onto the sliding guide structure 322. Multiple limiting holes 324 are required, and two locking pins 323 are preferably provided to achieve a fixed effect and reduce the need for locking. The cumbersome adjustment process can be resolved by rotating the locking pin 323 (similar to a bolt) or by using the tension of a spring (a spring needs to be installed between the locking pin 323 and the sliding guide structure 322) to move downwards and lock it into the limiting hole 324 for fixation. For adjustment accuracy, the limiting hole 324 can be shaped like a toothed groove structure. The bottom of the locking pin 323 is also provided with a toothed structure that slides between it and the sliding guide structure 322. When the locking pin 323 moves downwards, it pushes the toothed structure into the toothed groove structure, thus achieving fine adjustment.

[0026] The adjusting drive plate 321 is provided with an adjustment mechanism corresponding to the number of straightening rollers 34. The adjustment mechanism includes an adjusting toothed plate 3211, an adjusting screw 3212 and an adjusting worm 3213. The adjusting toothed plate 3211 slides in the adjusting drive plate 321 and meshes with the adjusting bushing 343. The inner side of the adjusting toothed plate 3211 is threadedly engaged with the adjusting screw 3212. The adjusting toothed plate 3211 is T-shaped with its long side protruding outward. The protruding side is provided with teeth that match the adjusting bushing 343. The inner side of the adjusting toothed plate 3211 is the short side, and the side wall of the short side is provided with threads that match the adjusting screw 3212.

[0027] Both the adjusting screw 3212 and the adjusting worm 3213 rotate within the adjusting drive plate 321. One end of the adjusting screw 3212 is equipped with a worm wheel, and the adjusting worm 3213 cooperates with this worm wheel. The adjusting worm 3213 extends to the outer part of the adjusting drive plate 321. The adjusting worm 3213 is driven by a tool to adjust the straightening roller 34 individually. During long-term use of the equipment, the straightening roller located in the middle of the feeding section bears greater extrusion and friction, and its wear rate is usually faster than that of the straightening roller at the edge. If the gap is calibrated by adjusting the entire gap, the preload of some straightening rollers will not meet the processing requirements. Either the preload is too large, which aggravates the wear of the steel wire surface, or the preload is insufficient, which cannot fully correct the curvature of the steel wire. By using a worm gear and worm shaft mechanism, operators only need to use conventional tools to rotate the exposed adjusting worm, which drives the adjusting screw at the corresponding position to rotate. This, in turn, moves the adjusting toothed plate corresponding to each straightening roller, completing the fine-tuning of the position of each straightening roller. There is no need to adjust all the straightening rollers one by one, which greatly reduces the difficulty of equipment maintenance and calibration. The overall adjustment time is less than 2 minutes, and it can also ensure that the straightening accuracy after wear compensation always meets the processing standards, extending the overall maintenance cycle of the equipment and reducing the long-term operating cost of the equipment.

[0028] The staggered S-shaped straightening roller structure allows the steel wire to undergo multiple bending deformations in both directions during its journey, fully releasing the residual rolling stress inside the steel wire. Compared with the traditional parallel straightening structure, it can more thoroughly eliminate the initial curvature of the steel wire, preventing stress rebound and re-bending after straightening. It can stably control the residual deflection of the steel wire within the industry standard range of ≤1mm / m, significantly improving the finished product qualification rate of straightening processing and solving the problems of insufficient straightening accuracy and incomplete stress elimination in traditional straightening equipment.

[0029] The traction mechanism includes a traction wheel 40 and a traction motor 41. The traction wheel 40 and the traction motor 41 are connected by a belt and are used to traction the workpiece and provide tension. The traction machine typically transmits power to the traction wheel, which is pressed together by the belt. The traction wheel 40 has an arc-shaped groove on its surface that matches the diameter of the steel wire being processed, ensuring full contact with the outer surface of the steel wire and providing sufficient traction friction. The traction mechanism is installed on the discharge side of the main straightening mechanism. The speed of the traction motor 41 can be steplessly adjusted via the control panel 11 on the straightening base 10, thereby controlling the travel speed of the steel wire and adapting to the straightening requirements of steel wires of different specifications and materials. When straightening large-diameter, high-hardness steel wires, the traction speed can be appropriately reduced to ensure sufficient straightening deformation; when straightening small-diameter, low-hardness steel wires, the traction speed can be increased to improve overall processing efficiency.

[0030] The cutting mechanism includes a cutting hydraulic cylinder 60, which is equipped with a cutter for cutting the workpiece. Specifically, the cutting hydraulic cylinder 60 is a hydraulically driven cutting hydraulic cylinder with stable power output and a fast cutting response speed. It can complete the cutting action within 1ms of receiving the cutting trigger signal, ensuring that the cutting position accuracy meets the fixed length requirements and avoiding problems such as excessive cutting length due to response lag. After cutting, the steel wire falls directly into the binding rack 70 installed at the equipment's discharge end, and slides down the inclined surface of the rack to the designated collection area for binding under its own weight.

[0031] The straightening base 10 is also equipped with a control panel 11 and a guide measuring sleeve 50. The control panel 11 is used to control the traction speed of the traction mechanism. The guide measuring sleeve 50 is a straightening and length-fixing component set between the traction mechanism and the cutting mechanism. It is used for guidance and can also be used to detect the travel distance of the steel wire. It works with the cutting mechanism to complete the fixed-length cutting and ensure that the length of the finished steel wire meets the processing requirements.

[0032] Working principle: The steel wire of the workpiece is first taken out from the unwinding reel and sequentially passed through the vertical straightening wheel set 20, the horizontal straightening wheel set 21, the main straightening inner shell 31, the traction wheel 40, the guide measuring sleeve 50, and the cutting hydraulic cylinder 60. Then, it is cut by the cutting hydraulic cylinder 60, and the steel wire falls onto the binding rack 70 for collection. The bent steel wire is first straightened vertically by the vertical straightening wheel set 20, which is perpendicular to the straightening base 10, and then straightened horizontally by the horizontal straightening wheel set 21. At this time, the initial pre-straightening of the steel wire is completed. In order to eliminate the large curvature of the steel wire and protect the subsequent main straightening mechanism, the steel wire then passes through multiple straightening wheels in the main straightening inner shell 31. Roller 34 bends the wire to produce plastic deformation. Through multiple forward and reverse bending, the residual deflection is reduced to ≤1mm / m (industry standard). After repeated bending, the curvature is gradually offset and tends to be straight (the original steel wire has an initial curvature). Then, the traction mechanism provides overall tension, so that the steel wire has a certain pulling speed, which is adjusted by the control panel 11. Then the steel wire passes through the guide measuring sleeve 50, which provides guidance and avoids the bending stress of the steel wire not being completely eliminated, so that it is still in a bent state after cutting. Finally, after the steel wire extends to the set length, it is cut by the cutting hydraulic cylinder 60 and falls onto the binding rack 70 for collection, thus completing the entire steel wire processing process.

[0033] When the wire type (diameter) is changed or the straightening roller 34 is worn, and the position of the upper and lower straightening rollers 34 needs to be adjusted, the locking pin 323 can be pulled out or rotated out first, and the corresponding upper and lower adjustment drive plates 321 can be pulled directly. At this time, the adjusting tooth plate 3211 is doubly locked by the adjusting screw 3212 and the adjusting worm gear 3213, so it is in a fixed state. When the adjustment drive plate 321 is pulled directly, the adjusting tooth plate 3211 can be moved directly. Then, the movement of the adjusting tooth plate 3211 drives the adjusting bushing 343 to rotate. Through the threaded connection between the adjusting bushing 343 and the threaded roller shaft 342, the straightening roller 34 can be moved up and down in the roller connecting plate 33 to adjust the position of the straightening roller 34. At this time, since all the adjusting tooth plates 3211 are engaged with the adjusting bushing 343, all the upper or lower straightening rollers 34 can be moved synchronously to move to the appropriate height as a whole, thereby quickly completing the overall adjustment of the straightening gap to adapt to different wires.

[0034] In the overall adjustment mode, by pulling out or rotating out the locking pin 323, the adjustment drive plate 321 and all the adjustment toothed plates 3211 form a rigid linkage connection. At this time, the double thread self-locking structure of the adjustment screw 3212 and the adjustment worm 3213 locks the adjustment toothed plates 3211 onto the adjustment drive plate 321. The operator does not need any tools or electric drive; by simply pulling the adjustment drive plate 321, all the upper or lower adjustment toothed plates 3211 can be moved synchronously. Then, through the threaded transmission between the adjustment bushing 343 and the threaded roller shaft 342, all the straightening rollers 34 are driven to rise and fall synchronously, completing the overall adjustment of the straightening gap. During this process, the double self-locking structure not only ensures the rigid linkage between the adjustment drive plate 321 and the adjustment toothed plates 3211, but also prevents the straightening rollers 34 from accidentally slipping during the adjustment process.

[0035] When the steel wire enters the main straightening inner shell 31, it still has initial bending stress. Therefore, the wear of the straightening roller 34 is generally different, resulting in the wear rate in the middle of the straightening roller 34 being greater than that on both sides. Therefore, it is necessary to adjust the straightening roller 34 individually. At this time, the adjusting worm 3213 can be rotated by using a tool, which will drive the adjusting screw 3212 to rotate, thereby causing the single adjusting tooth plate 3211 to slide. Then, the straightening roller 34 can be moved up and down, and the straightening roller 34 can be adjusted individually.

[0036] In the individual adjustment mode, rotating the single adjustment worm 3213 with a tool can drive the corresponding adjustment screw 3212 to rotate, thereby causing the single adjustment tooth plate 3211 to slide independently, realizing the independent lifting and lowering of the single straightening roller 34 to compensate for the gap changes caused by local wear.

[0037] In summary, this precast slab frame steel wire straightening and automatic binding integrated machine achieves two adjustment modes—overall and individual—through the cooperation of a single mechanism and a set of transmission chains: the adjusting bushing 343, the adjusting drive plate 321, and the adjusting toothed plate 3211. In the overall adjustment mode, the double-threaded self-locking structure of the adjusting screw 3212 and the adjusting worm 3213 locks the adjusting toothed plate 3211 onto the adjusting drive plate 321. Operators do not need tools or electricity; they can drive all straightening rollers 34 to rise and fall synchronously simply by manually pulling the adjusting drive plate 321. This simplifies operation and shortens the changeover and debugging time. In the individual adjustment mode, rotating a single adjusting worm 3213 with a tool drives the independent rise and fall of a single straightening roller 34. This compensates for uneven gaps caused by local wear, avoiding the loss of precision caused by replacing the entire set of straightening rollers or adjusting the whole machine due to local wear. This extends the service life of the straightening rollers and reduces maintenance costs.

[0038] By setting up a pre-straightening roller group, the steel wire is initially straightened in both the vertical and horizontal directions, eliminating the original large curvature bending deformation of the steel wire in advance. This not only reduces the impact of large curvature bending on the straightening rollers in the main straightening mechanism, reducing abnormal wear of the straightening rollers and extending the service life of the equipment, but also homogenizes the internal stress of the steel wire in advance, thereby reducing the processing pressure of the subsequent main straightening process. This avoids the problems of rapid wear of the main straightening components and unstable straightening effect, further improving the straightness compliance rate of the finished steel wire.
