Description

A steel straightening machine Technical Field

[0001] This utility model relates to the field of steel processing technology, specifically to a steel straightening machine. Background Technology

[0002] In the field of metal processing, the straightening roller assembly of a steel straightening machine is the core component for achieving steel straightening. It drives the steel to rotate through the friction between the rollers and the steel, and applies a straightening force to the steel by utilizing the specific arrangement of the rollers, thereby correcting the bending deformation of the steel.

[0003] However, most straightening roller sets currently on the market have certain design flaws. When driving the steel to rotate for straightening, due to the lack of effective limiting devices at both ends of the steel, the steel is prone to axial or radial displacement during the straightening process. This displacement causes the steel to deviate from the predetermined straightening path during the straightening process, resulting in uneven straightening forces on different parts of the steel, which seriously affects the straightening accuracy and effect.

[0004] For example, when steel undergoes axial movement, some areas may not be fully straightened, while other areas may suffer surface damage or even breakage due to excessive stress. Radial displacement alters the contact position between the steel and the rollers, disrupting the stable straightening force relationship, reducing straightening efficiency, and increasing the scrap rate. Furthermore, steel displacement can lead to equipment instability, accelerate wear on rollers and other components, shorten equipment lifespan, and increase production and maintenance costs for the company.

[0005] Therefore, it is urgent to design a straightening roller assembly with a steel limiting structure to solve the adverse effects of steel displacement on straightening in the existing technology. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a steel straightening machine.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0008] A steel straightening machine includes a fixed plate, and bases are provided on the front and rear sides of the top wall of the fixed plate. A round rod is rotatably connected to the inner wall between the bases through a bearing, and a cylinder is interference-fitted to the outer wall of the round rod.

[0009] A support plate is provided on the right side wall of the fixed plate, a cylinder is provided on the top wall of the support plate, a support tube is provided on the top wall of the cylinder, multiple sliding grooves are provided on the inner wall of the support tube, a motor is provided on the inner wall of the cylinder, a lead screw is locked to the output end of the motor through a coupling, a circular plate is threaded on the outer wall of the lead screw, multiple sliders are provided on the outer wall of the circular plate, a support rod is provided on the top wall of the circular plate, the top wall of the support rod extends out of the support tube and is provided with a clamping and rotating mechanism.

[0010] Furthermore, the clamping and rotating mechanism includes a top plate, with slide rails at both the front and rear ends of the left side of the top wall of the top plate, a connecting plate on the right side of the top wall of the top plate, a hydraulic telescopic rod on the right side wall of the connecting plate, a top seat on the left end wall of the hydraulic telescopic rod, pulleys at the four corners of the bottom wall of the top seat, a second motor on the top wall of the top seat, and a drive shaft locked to the output end of the second motor via a coupling. A clamping plate is provided on the left end wall of the drive shaft.

[0011] Furthermore, an anti-slip pad is provided on the left side wall of the clamp.

[0012] Furthermore, the outer wall of the lead screw is rotatably connected to the inner wall of the cylinder via bearing two.

[0013] Furthermore, the outer wall of the lead screw extends into the support rod of the hollow structure.

[0014] The beneficial effects of this utility model are:

[0015] The adjustable clamping structure enables precise positioning of both ends of the steel, effectively preventing axial movement and radial offset, ensuring stable rotation of the steel on the predetermined straightening path, and uniform force distribution in all parts, significantly reducing problems of insufficient straightening or excessive deformation caused by displacement. The unique dual-drive adjustment mechanism can quickly achieve precise matching between the clamping plate position and the diameter and length of the steel, eliminating the need for frequent mold changes and significantly reducing equipment investment costs for enterprises. Stable rotation of the steel effectively reduces abnormal friction and impact with the rollers, thus reducing roller wear rate. The integrated automatic system of motor drive and hydraulic control enables seamless connection of steel positioning, rotation detection, and straightening processes, shortening the time of a single straightening operation.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Referring to Figures 1-3, a steel straightening machine includes a fixed plate 1. The top wall of the fixed plate 1 is provided with bases 2 on both the front and rear sides. The inner wall between the bases 2 is rotatably connected to a round rod 3 through a bearing. The outer wall of the round rod 3 is interference-fitted with a cylinder 4.

[0024] A support plate 5 is provided on the right side wall of the fixed plate 1. A cylinder 6 is provided on the top wall of the support plate 5. A support cylinder 7 is provided on the top wall of the cylinder 6. Multiple sliding grooves are provided on the inner wall of the support cylinder 7. A motor 8 is provided on the inner wall of the cylinder 6. A lead screw 9 is locked to the output end of the motor 8 through a coupling. A circular plate 10 is threadedly connected to the outer wall of the lead screw 9. Multiple sliders 11 are provided on the outer wall of the circular plate 10. A support rod 12 is provided on the top wall of the circular plate 10. The top wall of the support rod 12 extends out of the support cylinder 7 and is provided with a clamping and rotating mechanism.

[0025] Furthermore, the clamping and rotating mechanism includes a top plate 13. Slide rails 14 are provided at both the front and rear ends of the left side of the top wall of the top plate 13. A connecting plate 15 is provided on the right side of the top wall of the top plate 13. A hydraulic telescopic rod 16 is provided on the right side wall of the connecting plate 15. A top seat 17 is provided on the left end wall of the driving mechanism of the hydraulic telescopic rod 16. Pulleys 18 are provided at the four corners of the bottom end wall of the top seat 17. A second motor 19 is provided on the top wall of the top seat 17. The output end of the second motor 19 is locked to a drive shaft 20 via a coupling. A clamping plate 2 is provided on the left end wall of the drive shaft 20. 1. After the hydraulic telescopic rod 16 is started, it pushes the top seat 17, motor 29, drive shaft 20, clamping plate 21 and anti-slip pad 22 and other structures to move inwards via pulley 18 on motor 29. The clamping plates 21 on both sides of the steel move inwards at the same time, which can perform positioning operation on the steel. After the two clamping plates 21 clamp the steel, the motor 29 is started to cause the drive shaft 20 to drive the clamping plates 21 and anti-slip pad 22 to rotate. The clamping plates 21 on both sides drive the steel to rotate on the cylinder 4 for detection and adjustment.

[0026] Furthermore, an anti-slip pad 22 is provided on the left side wall of the clamping plate 21. After the motor 21 is started, the drive shaft 20 drives the clamping plate 21 and the anti-slip pad 22 to rotate. The clamping plates 21 on both sides drive the steel to rotate and be adjusted on the cylinder 4. The anti-slip pad 22 increases the friction between the clamping plate 21 and the steel, ensuring that the clamping plate 21 drives the steel to rotate stably.

[0027] Furthermore, the outer wall of the lead screw 9 is rotatably connected to the inner wall of the cylinder 6 through the bearing 2. The bearing 2 fixes the lead screw 9 and facilitates the rotation of the lead screw 9 through the bearing 2.

[0028] Furthermore, the outer wall of the lead screw 9 extends into the hollow support rod 12, effectively reducing the height of the main body of the device.

[0029] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0030] One specific application of this embodiment is:

[0031] In use, the two devices are set up symmetrically opposite each other and fastened to the pre-set mounting holes on the base of the straightening roller group of the straightening machine with high-strength bolts to ensure accurate alignment and stable connection between the device and the straightening roller group. After installation, the steel feeding mechanism is started to smoothly transport the steel to be straightened between the two devices, so that the two ends of the steel are placed in the arc-shaped receiving grooves at the top of the cylinder 4 of the corresponding device. The cylinder 4 can effectively distribute the pressure of the steel's own weight through its anti-slip and wear-resistant coating and specific arc design, while providing initial positioning support for the steel.

[0032] Once the steel is in place, the operator starts motor 8 via the equipment control panel according to the actual diameter and length parameters of the steel. Motor 8 drives screw 9 to rotate precisely through the coupling. The rotation of screw 9 causes the circular plate 10, which is threaded to it, to rise and fall smoothly in the vertical direction. The circular plate 10, through the precise cooperation of slider 11 and slide rail, synchronously drives components such as support rod 12, top plate 13, and connecting plate 15 to move up and down, thereby realizing the height adjustment of key components such as top seat 17, motor 29, and clamping plate 21. During this process, the coaxiality data between clamping plate 21 and steel is monitored in real time by laser range sensor and fed back to the control system for automatic fine adjustment to ensure that the axis of clamping plate 21 is precisely aligned with the axis of steel.

[0033] After the height adjustment is completed, the hydraulic telescopic rod 16 is activated. The stable pressure output by the hydraulic system pushes the top seat 17, causing the motor 19, drive shaft 20, clamping plate 21 and anti-slip pad 22 to move synchronously inward in the horizontal direction on the slide rail of the motor 19 via pulley 18. When the clamping plates 21 on both sides contact the steel, the hydraulic system automatically switches to the pressure holding mode, so that the clamping plates 21 clamp and position the steel with constant pressure. At the same time, the toothed texture on the surface of the anti-slip pad 22 tightly engages with the surface of the steel, effectively preventing slippage during the clamping process.

[0034] After the steel is positioned, motor 19 is started. Motor 19 drives the two side clamps 21 and anti-slip pads 22 to rotate synchronously through drive shaft 20. Under the action of friction, the steel rotates on the support surface of cylinder 4. At this time, multiple sets of infrared flaw detectors and laser straightness detectors installed around the device perform all-round real-time detection on the rotating steel and transmit the bending data synchronously to the control system. When a bending part of the steel is detected, the control system automatically plans the straightening path and sends a command to the straightening and pressurizing mechanism to start the straightening program.

[0035] During the straightening process, the hydraulic telescopic rod 16 releases pressure according to the control system command, driving the clamping plate 21 to detach from the steel, providing sufficient operating space for the straightening and pressurizing mechanism. After the straightening is completed, the hydraulic telescopic rod 16 moves again, driving the clamping plate 21 to re-clamp the steel, and the motor 19 drives the steel to rotate for a second inspection to ensure that the straightening accuracy meets the process requirements. The entire operation process is automated and closed-loop controlled by the electromechanical-hydraulic integrated control system, which effectively improves the straightening efficiency and quality stability.

[0036] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
