Description

Technical Field

[0001] This invention relates to the field of strip steel processing technology, and in particular to a limiting device for reducing edge wear. Background Technology

[0002] In steel plate processing production lines, after the steel plates are sheared by the splitting shearing equipment, a centering device is needed to adjust the position of the steel plates to ensure the accuracy of subsequent processes. In the production of thick plates, the steel plates are usually sent to the next process along one edge. More precisely, the centering device should be an edge-adjusting device. The edge limiting structure of existing centering devices mostly uses baffles as limiting components. That is, the baffles fixed on the fixed side of the roller conveyor contact the edge of the steel plate to be centered, guiding the steel plate to align with the edge, and then transporting it after alignment.

[0003] However, the aforementioned existing technology has obvious drawbacks: the steel plate to be aligned and the edge limiting baffle are in sliding contact. During the alignment process, the friction between the two will cause severe wear on the limiting baffle and the edge of the steel plate, affecting the positioning accuracy of the steel plate. On the one hand, the limiting baffle needs to be replaced frequently after it is worn, which increases the equipment maintenance cost and downtime. On the other hand, the wear on the edge of the steel plate will affect the processing accuracy and finished product quality of the steel plate, especially in steel plate processing scenarios with high precision requirements, this problem is more prominent.

[0004] Therefore, to address the issue of reducing edge wear on the steel plate during high-precision steel plate processing, a limiting device to reduce edge wear can be designed. When this device is used, as the centering device pushes the strip to the fixed side, the edge of the steel plate first contacts the surface of the vertical guide roller. The vertical guide roller rotates within the bearing housing. At this time, the radial impact force generated by the steel plate on the vertical guide roller is transmitted to the L-shaped plate through the sliding seat. The buffer mechanism deforms and absorbs the impact energy. During the roller conveyor transport of the steel plate, the edge of the steel plate maintains rolling contact with the vertical guide roller. The rotation of the vertical guide roller converts traditional sliding friction into rolling friction, significantly reducing the wear degree between the edge of the steel plate and the limiting device. In summary, this device, through the rolling contact design of the vertical guide roller, converts the sliding friction between the edge of the steel plate and the limiting device into rolling friction, significantly reducing the wear rate of both, extending the service life of the vertical guide roller, and reducing edge wear on the steel plate to be centered. Summary of the Invention

[0005] The existing edge limiting structure on the fixed side of the roller conveyor mostly uses baffles as the limiting components. The steel plate to be aligned and the edge limiting baffle are in sliding contact. The friction between the two will cause severe wear on the edge of the limiting baffle and the steel plate. Therefore, when used in steel plate processing scenarios with high precision requirements, it is inconvenient to reduce the wear on the edge of the aligned steel plate.

[0006] The technical solution of the present invention is as follows: a limiting device for reducing edge wear, including a fixed seat, a sliding seat provided on one side of the fixed seat, detachable bearing seats symmetrically provided on the outer walls of the upper and lower ends of the sliding seat, and a vertical guide roller, the vertical guide roller being rotatably connected between the two sets of bearing seats, L-shaped plates being symmetrically and fixedly connected to the inner walls of the upper and lower ends of the sliding seat, and a buffer mechanism being provided between each set of L-shaped plates and the fixed seat.

[0007] Preferably, when using this limiting device that reduces edge wear, when the centering device pushes the strip to the fixed side, the edge of the steel plate first contacts the roller surface of the vertical guide roller. The vertical guide roller rotates within the bearing housing. At this time, the radial impact force generated by the steel plate on the vertical guide roller is transmitted to the L-shaped plate through the sliding seat. At this time, the buffer mechanism deforms and absorbs the impact energy. During the roller conveyor transport of the steel plate, the edge of the steel plate maintains rolling contact with the vertical guide roller. The rotation of the vertical guide roller converts the traditional sliding friction into rolling friction, significantly reducing the wear degree between the edge of the steel plate and the limiting device. In summary, this device, through the rolling contact design of the vertical guide roller, converts the sliding friction between the edge of the steel plate and the limiting device into rolling friction, significantly reducing the wear rate of both, extending the service life of the vertical guide roller, and reducing the edge wear of the steel plate to be centered.

[0008] Preferably, rotating bearings are rotatably mounted on both the upper and lower ends of the vertical guide roller, and the rotating bearings are rotatably connected inside the bearing housing.

[0009] Preferably, mounting holes are provided on the outer walls of the upper and lower ends of the sliding seat and on both sides of the bearing seat. Mounting bolts are installed inside the mounting holes and are threaded into the mounting holes.

[0010] Preferably, the buffer mechanism includes shock absorbers, with shock absorbers symmetrically arranged between each group of L-shaped plates and the fixed base.

[0011] Preferably, each L-shaped plate has a sliding wheel rotatably connected inside, and the upper and lower inner walls of the fixed seat have sliding grooves, with the sliding wheel slidably connected inside the sliding grooves.

[0012] Preferably, the fixing base is fixedly connected to fixing ears on both sides, fixing holes are opened inside the fixing ears, fixing bolts are installed inside the fixing holes, and the fixing bolts are threadedly connected to the fixing holes.

[0013] Preferably, a detachable connecting seat is provided on one side of the sliding seat, and the outer wall of the connecting seat is rotatably connected to the horizontal guide roller.

[0014] Preferably, a connecting block is fixedly connected above the sliding seat, and two sets of connecting holes are opened through the inner wall of the connecting block and the inner wall of the upper end of the fixed seat.

[0015] Preferably, a U-shaped connector is connected through the two sets of connecting holes, and a groove is opened on the outer wall of the connecting block, with the connecting end of the U-shaped connector embedded in the groove of the connecting block.

[0016] Preferably, a connecting nut is fitted onto the threaded end of the U-shaped connector, and the connecting nut is threadedly connected to the threaded end of the U-shaped connector.

[0017] The beneficial effects of this invention are:

[0018] 1. When using this limiting device to reduce edge wear, when the centering device pushes the strip to the fixed side, the edge of the steel plate first contacts the roller surface of the vertical guide roller. The vertical guide roller rotates in the bearing seat. At this time, the radial impact force generated by the steel plate on the vertical guide roller is transmitted to the L-shaped plate through the sliding seat. At this time, the buffer mechanism deforms and absorbs the impact energy. During the roller conveyor transport of the steel plate, the edge of the steel plate maintains rolling contact with the vertical guide roller. The rotation of the vertical guide roller converts the traditional sliding friction into rolling friction, which greatly reduces the wear degree between the edge of the steel plate and the limiting device. In summary, this device, through the rolling contact design of the vertical guide roller, converts the sliding friction between the edge of the steel plate and the limiting device into rolling friction, significantly reducing the wear rate of both, extending the service life of the vertical guide roller, and reducing the edge wear of the steel plate to be centered.

[0019] 2. Firstly, the damping mechanism of the shock absorber can effectively absorb the impact energy of the steel plate, avoid equipment damage caused by rigid collisions, and improve the impact resistance of the device. Secondly, the modular vertical guide roller design, combined with the convenient mounting bolt structure, allows the replacement of a single vertical guide roller to be completed in a short time, significantly reducing maintenance costs and downtime. Thirdly, the uniform thrust characteristics of rolling friction avoid the steel plate misalignment problem caused by uneven contact in traditional sliding friction, further improving alignment accuracy and transportation stability, ultimately achieving the comprehensive benefits of reducing maintenance costs, extending equipment life, and improving production efficiency.

[0020] 3. The addition of horizontal guide rollers achieves dual limiting of the upper and lower surfaces of the steel plate. Combined with the edge limiting function of vertical guide rollers, a three-dimensional limiting system is formed, which effectively prevents the steel plate from shifting and moving during transportation and ensures centering accuracy.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1 Please see Figure 1 and Figure 3 The present invention provides an embodiment of a limiting device for reducing edge wear, comprising a fixed seat 1, a sliding seat 2 disposed on one side of the fixed seat 1, detachable bearing seats 3 symmetrically disposed on the outer walls of the upper and lower ends of the sliding seat 2, and a vertical guide roller 4 rotatably connected between two sets of bearing seats 3, and L-shaped plates 5 symmetrically and fixedly connected to the inner walls of the upper and lower ends of the sliding seat 2, with a buffer mechanism disposed between each set of L-shaped plates 5 and the fixed seat 1.

[0024] Please see Figure 2 and Figure 3 The vertical guide roller 4 is rotatably fitted with rotating bearings 6 at both its upper and lower ends. The rotating bearings 6 are rotatably connected to the inside of the bearing seat 3. The vertical guide roller 4 rotates within the bearing seat 3 through the rotating bearings 6 fitted at its upper and lower ends. Mounting holes 7 are opened on the outer walls of the upper and lower ends of the sliding seat 2 and on both sides of the bearing seat 3. Mounting bolts 8 are installed inside the mounting holes 7 and are threadedly connected to the mounting holes 7. When a vertical guide roller 4 is damaged due to long-term use or accident, the bearing seat 3 and the vertical guide roller 4 assembly can be quickly replaced simply by removing the mounting bolts 8 from the outer walls of the upper and lower ends of the sliding seat 2 and the two sides of the bearing seat 3.

[0025] Please see Figure 2 and Figure 3The buffer mechanism includes a shock absorber 9. Each set of L-shaped plates 5 is symmetrically arranged between the shock absorber 9 and the fixed seat 1. The shock absorber 9 can effectively absorb the impact energy of the steel plate, avoid equipment damage caused by rigid collision, and improve the impact resistance of the device. Each set of L-shaped plates 5 is rotatably connected to a sliding wheel 10. The upper and lower inner walls of the inner cavity of the fixed seat 1 are provided with sliding grooves 21. The sliding wheel 10 is slidably connected to the inside of the sliding groove 21. The sliding wheel 10 on the inner side of the L-shaped plate 5 slides smoothly along the sliding groove 21 of the inner cavity of the fixed seat 1, ensuring the linear motion trajectory of the sliding seat 2 when subjected to force.

[0026] Please see Figure 2 and Figure 3 The fixed base 1 has fixed ears 11 on both sides. The fixed ears 11 have fixed holes 12 inside. The fixed holes 12 are equipped with fixed bolts 13. The fixed bolts 13 are threaded to the fixed holes 12. The limit device can be quickly replaced by simply removing multiple sets of fixed bolts 13.

[0027] When using this limiting device to reduce edge wear, the working principle of the present invention is as follows: the limiting device is installed on the fixed side of the shearing conveyor roller, and the whole is fixed by the fixing bolts 13 of the fixing ears 11 on both sides of the fixing seat 1. At the same time, the edge limiting baffle of the centering device is replaced with a pulley assembly and used in conjunction with the vertical guide roller 4.

[0028] When the centering device pushes the strip to the fixed side through the pulley assembly, the edge of the steel plate first contacts the roller surface of the vertical guide roller 4. The vertical guide roller 4 rotates in the bearing seat 3 through the rotating bearing 6 rotatably sleeved at the upper and lower ends. At this time, the radial impact force generated by the steel plate on the vertical guide roller 4 is transmitted to the L-shaped plate 5 through the sliding seat 2. The shock absorber 9 symmetrically arranged between the L-shaped plate 5 and the fixed seat 1 deforms and absorbs the impact energy. At the same time, the sliding wheel 10 on the inner side of the L-shaped plate 5 slides smoothly along the sliding groove 21 in the inner cavity of the fixed seat 1, ensuring the linear motion trajectory of the sliding seat 2 when under force.

[0029] During the process of transporting steel plates on roller conveyors, the two sides of the steel plates maintain rolling contact with the vertical guide roller 4 and the pulley assembly, respectively. The rotation of the vertical guide roller 4 transforms the traditional sliding friction into rolling friction, which greatly reduces the wear on the edges of the steel plates and the limiting device.

[0030] The vertical guide roller 4 adopts a modular design. When a vertical guide roller 4 is damaged due to long-term use or accident, the mounting bolts 8 on both sides of the upper and lower outer walls of the sliding seat 2 and the bearing seat 3 can be removed to quickly replace the bearing seat 3 and the vertical guide roller 4 assembly. Multiple vertical guide rollers 4 with the same structure are arranged at intervals between the two rollers of the shearing roller table to form a continuous blocking array and jointly bear the impact force on the edge of the steel plate.

[0031] In summary, firstly, this device, through the rolling contact design of the vertical guide roller 4, transforms the sliding friction between the steel plate edge and the limiting device into rolling friction, significantly reducing the wear rate of both and extending the service life of the vertical guide roller 4, while also reducing edge wear of the steel plate to be aligned. Secondly, the buffer mechanism of the shock absorber 9 can effectively absorb the impact energy of the steel plate, avoiding equipment damage caused by rigid collisions and improving the impact resistance of the device. Thirdly, the modular design of the vertical guide roller 4, combined with the convenient mounting bolt 8 structure, allows the replacement of a single vertical guide roller 4 to be completed in a short time, greatly reducing maintenance costs and downtime. Fourthly, the uniform thrust characteristics of rolling friction avoid the steel plate misalignment problem caused by uneven contact in traditional sliding friction, further improving alignment accuracy and transportation stability, ultimately achieving the comprehensive benefits of reducing maintenance costs, extending equipment life, and improving production efficiency.

[0032] Through the above steps, when using this limiting device that reduces edge wear, when the centering device pushes the strip to the fixed side, the edge of the steel plate first contacts the roller surface of the vertical guide roller 4. The vertical guide roller 4 rotates in the bearing seat 3. At this time, the radial impact force generated by the steel plate on the vertical guide roller 4 is transmitted to the L-shaped plate 5 through the sliding seat 2. At this time, the buffer mechanism deforms and absorbs the impact energy. During the roller conveyor transport of the steel plate, the edge of the steel plate and the vertical guide roller 4 maintain rolling contact. The rotation of the vertical guide roller 4 transforms the traditional sliding friction into rolling friction, which greatly reduces the wear degree between the edge of the steel plate and the limiting device. In summary, this device, through the rolling contact design of the vertical guide roller 4, transforms the sliding friction between the edge of the steel plate and the limiting device into rolling friction, significantly reducing the wear rate of both, extending the service life of the vertical guide roller 4, and reducing the edge wear of the steel plate to be centered.

[0033] Example 2 Please see Figure 4 and Figure 6 The difference from Embodiment 1 is that a detachable connecting seat 14 is provided on one side of the sliding seat 2. The outer wall of the connecting seat 14 is rotatably connected to the horizontal guide roller 15. The upper part of the sliding seat 2 is fixedly connected to the connecting block 16. Two sets of connecting holes 17 are opened through the inner wall of the connecting block 16 and the upper inner wall of the fixed seat 1. The U-shaped connecting piece 18 is connected through the two sets of connecting holes 17.

[0034] Please see Figure 5 and Figure 6 The outer wall of the connecting block 16 has a groove 19. The connecting end of the U-shaped connector 18 is embedded in the groove 19 of the connecting block 16. The threaded end of the U-shaped connector 18 is fitted with a connecting nut 20, and the connecting nut 20 is threadedly connected to the threaded end of the U-shaped connector 18. A horizontal guide roller 15 can be installed on the connecting seat 14, which is fastened to the connecting nut 20 via a U-shaped connector 18 on one side of the sliding seat 2. The horizontal guide roller 15 is rotatably connected to the outer wall of the connecting seat 14, forming a secondary limit on the upper surface of the steel plate to prevent vertical movement during transportation.

[0035] The addition of the horizontal guide roller 15 achieves dual limiting of the upper and lower surfaces of the steel plate. Combined with the edge limiting function of the vertical guide roller 4, it forms a three-dimensional limiting system, which effectively prevents the steel plate from shifting and moving during transportation and ensures centering accuracy.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
