Description

Technical Field

[0001] This utility model relates to the field of steel rolling production technology in the metallurgical industry, specifically to an offline steel turning machine. Background Technology

[0002] Steel flipping machines are key auxiliary equipment on steel rolling and finishing production lines in steel enterprises. Their main function is to smoothly and accurately flip steel plates 180° for subsequent processes such as double-sided quality inspection, grinding, and marking. The stability, accuracy, and adaptability of the steel flipping process to steel plates of different specifications directly affect the production line's operating efficiency, product quality, and operational safety.

[0003] Currently, the mainstream offline steel turning machines are mainly divided into two categories: mechanical clamping type and roller turning type.

[0004] Mechanical clamping steel flipping machine: After the steel is clamped by a rigid clamping component, the drive mechanism rotates the clamping component to flip it. To ensure stable clamping, the clamping component is mostly made of high-strength metal, and the clamping force must be greater than the weight of the steel to prevent slippage;

[0005] Roller-type steel turning machine: Steel is supported by multiple sets of rollers with fixed spacing. The steel is turned over by the difference in speed or the change in tilt angle between the rollers. The surface of the rollers is usually made of smooth metal or rubber.

[0006] However, for mechanical clamping equipment, the rigid clamping components are in hard contact with the steel surface. If the clamping force is not properly controlled, the edges of the clamping components can easily squeeze the steel surface, forming indentations or scratches. If there are impurities such as oxide scale or rust on the steel surface, these impurities will be squeezed and scraped by the clamping components during clamping, forming irreversible scratches. Especially for high-precision cold-rolled steel plates, alloy profiles, and other steels with high surface quality requirements, such scratches can directly lead to product downgrading or scrapping, increasing production costs.

[0007] For roller-turning equipment, most have a fixed structural design, which cannot be flexibly adjusted according to the size of the steel. This means that the equipment can only be used with steel of specific specifications. The roller spacing and roller group tilt angle of roller-turning equipment are mostly fixed at the factory, which can only be used with steel of specific cross-sectional dimensions. When production needs change or different specifications of steel need to be processed, the machine must be stopped, disassembled, and the clamping components or roller groups must be replaced. The adjustment process is cumbersome, and multiple sets of parts adapted to different sizes need to be stocked. This not only reduces production efficiency but also increases the cost of equipment purchase and maintenance. Utility Model Content

[0008] This application provides an offline steel turning machine, which can effectively solve the problems in the background art.

[0009] To achieve the above objectives, this application provides the following technical solution: an offline steel turning machine, including a vertical plate, with multiple bases linearly and evenly distributed on both the left and right ends of the outer side of the vertical plate; a horizontal moving mechanism is installed on the upper surface of the base, and a hydraulic cylinder is installed on the horizontal moving mechanism, with the telescopic end of the hydraulic cylinder connected to a support plate through a hinge support.

[0010] Both ends of the upper surface of the vertical plate are rotatably connected to L-shaped nylon blocks via hinge supports. Multiple guide rods are evenly distributed at the ends of the L-shaped nylon blocks, and the guide rods are slidably connected to the support plate.

[0011] Preferably, the upper surface of the tray is evenly distributed with omnidirectional ball supports.

[0012] Preferably, the horizontal moving mechanism includes a slide rail mounted on the base and perpendicular to the vertical plate, a slider slidably connected to the upper surface of the slide rail, a hydraulic cylinder one mounted on the upper surface of the slider, a hydraulic cylinder two mounted on the outer side of the vertical plate, and the telescopic end of the hydraulic cylinder two connected to the outer side of the slider.

[0013] Preferably, the tray has a through hole through which the guide rod passes.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] 1. This application effectively avoids the problems of indentation and scratches caused to the steel surface by traditional mechanical clamping steel turning machines by adopting non-metallic flexible contact components such as L-shaped nylon blocks and universal ball supports, and significantly improves the surface quality of the steel after turning. It is especially suitable for high-precision cold-rolled plates, alloy materials and other materials with strict surface requirements.

[0016] 2. This steel turning machine, through the coordinated action of the horizontal moving mechanism and the hydraulic cylinder, can flexibly adjust the position of the pallet, thereby adapting to the turning requirements of steel of different specifications. Size adaptation can be completed without replacing parts, which improves the versatility and production efficiency of the equipment and reduces equipment maintenance and spare parts costs.

[0017] 3. The overall structure is reasonably designed. The sliding connection between the guide rod and the support plate, as well as the support of the hinge support, ensures the stability and controllability of the flipping process, improves the safety of operation and the flipping accuracy. At the same time, the cooperation between the hydraulic system and the moving mechanism realizes automated control, reduces the intensity of manual operation, and is suitable for integrated application in modern steel rolling production lines.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Figure 2 The orientations or positional relationships shown are for the convenience of describing this application and simplifying the description only, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. When a feature is referred to as "set", "fixed", or "connected" to another feature, it can be directly set, fixed, or connected to the other feature, or it can be indirectly set, fixed, or connected to the other feature.

[0023] Please see Figure 1-2 This application provides the following technical solutions: Please refer to Figure 1 and Figure 2 This application provides an offline steel turning machine, including a vertical plate 6, which serves as the main support structure. Multiple bases 3 are linearly and evenly distributed on the left and right ends of the vertical plate 6's outer side. The bases 3 are fixed to the foundation or equipment base with high-strength bolts to ensure the stability of the entire machine. A horizontal moving mechanism is installed on the upper surface of each base 3.

[0024] The horizontal moving mechanism includes a slide rail 2 fixedly mounted on the base 3 and arranged perpendicularly to the longitudinal centerline of the vertical plate 6. The slide rail 2 uses a high-precision linear guide to ensure smooth movement and low friction. A slider 4 is mounted on the slide rail 2, and the slider 4 can slide back and forth along the slide rail 2. A hydraulic cylinder 1 is fixedly mounted on the upper surface of the slider 4 by bolts. A second hydraulic cylinder 5 is installed at a corresponding position on the outer side of the vertical plate 6, and the telescopic end of the second hydraulic cylinder 5 is rigidly connected to the outer side of the slider 4 through a flange. By extending and retracting the second hydraulic cylinder 5, the slider 4 and all its components can be driven to move precisely along the slide rail 2, thereby achieving horizontal position adjustment to accommodate steel of different widths.

[0025] The telescopic end of hydraulic cylinder 1 is connected to pallet 7 via hinge support 12. Hinge support 12 is a heavy-duty hinge with self-lubricating bearings, allowing pallet 7 to rotate within a certain angle range around the hinge point under the push of hydraulic cylinder 1. Pallet 7 is preferably made of Q345B steel plate, possessing sufficient strength and rigidity. Multiple universal ball supports 8 are evenly distributed on the upper surface of pallet 7 via an array of countersunk screws. Each universal ball support 8 consists of a ball seat and high-hardness balls, with the balls partially exposed on the pallet surface, allowing for low-resistance rolling in any direction. This supports the steel to be overturned, greatly reducing friction between the bottom of the steel and the equipment, and preventing scratches.

[0026] The upper surface of the vertical plate 6 is rotatably connected to L-shaped nylon blocks 10 at both ends via hinge supports 9. The hinge supports 9 also employ a pin-shaft structure, allowing the L-shaped nylon blocks 10 to be flipped outwards or reset inwards. The L-shaped nylon blocks 10 are made of wear-resistant nylon material, possessing a tough texture that will not damage the steel surface. Multiple guide rods 11 are evenly distributed in an array at their ends (i.e., the horizontal section). The guide rods 11 are chrome-plated optical shafts with high hardness and smoothness. Correspondingly, through holes matching the number and position of the guide rods 11 are provided on the support plate 7. The guide rods 11 pass through these through holes, forming a sliding fit with the support plate 7. This design ensures that when the support plate 7 undergoes pitching motion driven by the hydraulic cylinder 1, the guide rods 11 guide and limit the movement of the support plate 7, ensuring accurate and smooth motion and preventing uneven loading or jamming.

[0027] In use: When in use, the operator first starts the equipment through the control system. According to the width of the steel to be flipped, the operator controls the hydraulic cylinder 5 to move the slider 4 and the entire lifting unit along the slide rail 2 to the appropriate position.

[0028] The steel is hoisted onto pallet 7, where it is supported by the ball joint support 8. The control system commands the hydraulic cylinders 1 on both sides to slowly extend, pushing pallet 7 to rotate upward around the axis of hinge support 12. Pallet 7 smoothly tilts upward, thus supporting the steel and gradually turning it around its contact line with the L-shaped nylon stop 10. After the pallets 7 on both sides clamp the steel plate to be turned, both pallets 7 rotate in the direction to be turned under the control of hydraulic cylinder 1 until the steel has turned 90 degrees. Then, one pallet 7 disengages, and the other pallet 7 lifts the steel plate and flattens it. The ball joint support 8 allows for slight relative displacement of the steel during the turning process, further preventing surface scratches.

[0029] When one hydraulic cylinder (1) extends fully, the pallet 7 tilts to its maximum angle, completing the flipping action. Then, the other hydraulic cylinder (1) retracts, smoothly restoring the pallet 7 to a horizontal position. The operator can then lift the flipped steel away to begin the next cycle of operation.

[0030] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
