Description

Technical Field

[0001] This utility model relates to the field of steel cutting anti-deviation technology, and in particular to a steel cutting device with an anti-deviation structure. Background Technology

[0002] In the steel plate processing industry, precise cutting is a core step in ensuring the accuracy of subsequent manufacturing. As a basic raw material for industries such as machinery manufacturing and construction engineering, the cutting quality of steel plates directly affects the structural strength and assembly accuracy of the final product. The feeding stability of the cutting machine is a key factor determining the cutting accuracy. Due to uneven weight distribution of the steel plate and errors in the parallelism of the guide rollers, lateral deviation is prone to occur during the feeding process, leading to skewed cuts and out-of-tolerance dimensions. This not only reduces the material yield but may also cause safety hazards such as equipment collisions.

[0003] In the steel plate feeding operation on a cutting machine, the guide roller drives the steel plate to move along a preset trajectory through friction, providing a stable processing reference for the cutting mechanism. However, during the conveying process of the guide roller, the steel plate is frequently affected by factors such as roller surface wear and irregular edges of the plate, resulting in lateral deviation. If not corrected in time, this can cause quality defects such as uneven shearing diagonals and diagonal lines on the surface.

[0004] The commonly used anti-deviation solution in the industry is to symmetrically install screw-adjustable limit anti-deviation plates on both sides of the machine tool. These plates form a mechanical limit by contacting the side of the steel plate. However, the mechanical transmission method of screw adjustment has a slow response speed. When the size of the steel plate changes, the screw needs to be manually adjusted to change the position of the anti-deviation plate, which cannot achieve real-time dynamic correction and is difficult to adapt to the precision control requirements of high-speed feeding scenarios. Secondly, the rigid anti-deviation plate has hard contact with the side of the steel plate. The continuous rigid friction generated during the feeding process will cause scratches, curling, and other damage to the edge of the steel plate, which is difficult to meet the dual requirements of timely anti-deviation response and material protection safety in steel plate cutting. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steel cutting device with an anti-deviation structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel cutting device with an anti-deviation structure, comprising an operating machine tool, wherein multiple feeding rollers are uniformly rotatably installed on the inner side of one end of the operating machine tool, a drive box is fixedly installed on the side of the operating machine tool near the feeding rollers, a hydraulic cylinder is installed on the outer end of the drive box, the output end of the hydraulic cylinder extends through into the interior of the drive box and is fixedly installed with a movable plate, and multiple connecting rods are hinged on both sides of the movable plate; Multiple guide rails are evenly and continuously provided on one side of the machine tool.

A rotating cylinder is sleeved on the outside of the vertical rod. A concave plate is fixedly installed at the end of the slide block away from the vertical rod. The side of the multiple connecting rods away from the movable plate is hinged to the inner wall of the concave plate.

[0007] Preferably, a screw hole is provided at the end of the vertical rod away from the slide block, the rotating cylinder is rotatably mounted on the surface of the vertical rod, and a limit screw is connected to the internal thread of the screw hole.

[0008] Preferably, the plurality of guide rails are connected to the interior of the drive box, and the plurality of guide rails are respectively located between two adjacent feed rollers.

[0009] Preferably, multiple grooves are evenly provided on both sides of the movable plate, and shafts are fixedly installed at both ends of the connecting rod.

[0010] Preferably, one end of the connecting rod is rotatably mounted on the inner wall of the groove via a shaft, and the end of the connecting rod away from the movable plate is rotatably mounted on the inner wall of the concave plate via a shaft.

[0011] Preferably, two limiting posts are fixedly installed inside the drive box, and guide holes are respectively opened at both ends of the movable plate. The movable plate is slidably installed on the surface of the limiting posts through the two guide holes.

[0012] Preferably, a frame is fixedly installed on the side of the machine tool away from the feed roller, a linear guide rail is fixedly installed on the inner side of the frame, and a laser cutting device is slidably installed on the surface of the linear guide rail.

[0013] Preferably, the laser cutting device is connected to the linear guide rail via a slider adapted to the linear guide rail, and a laser head is fixedly installed at the end of the laser cutting device.

[0014] In summary, this utility model has the following beneficial effects: 1. This utility model utilizes a hydraulic cylinder to drive a movable plate linkage rod, which moves the slide block within the guide rail to adjust the position of the rotating drum. Each pair of adjacent feeding rollers is equipped with this anti-deviation structure. The hydraulic cylinder drive provides a faster response, eliminating the need for manual operation. It can dynamically adjust in real time according to the steel plate size, precisely adapting to high-speed feeding scenarios and effectively preventing steel plate deviation caused by adjustment lag. Furthermore, multiple anti-deviation structures create multiple uniform limits on the steel plate, forming a stable guide in conjunction with the feeding rollers. This significantly improves the stability of steel plate feeding and the accuracy of cutting dimensions, reducing material scrap rates caused by deviation and minimizing production cost losses for enterprises. 2. This utility model utilizes a rotating drum mounted on the outside of the vertical rod to create rolling friction between the drum and the side of the steel plate during conveying. This replaces the sliding friction between the existing rigid anti-deviation plate and the steel plate, reducing frictional damage to the side of the steel plate caused by the anti-deviation components. It completely avoids quality defects such as scratches and curling at the edges of the steel plate, especially meeting the processing requirements of cold-rolled steel plates and other products with high surface finish requirements. Furthermore, the drum can adaptively rotate with the steel plate feeding direction without affecting the steel plate conveying efficiency. While ensuring the anti-deviation effect, it effectively protects the surface quality of the steel plate, increases product added value, and enhances the product's competitive advantage in the market. 3. In this utility model, the end of the vertical rod is fixed to the rotating drum by a screw hole and a limiting screw. When the rotating drum becomes worn or deformed due to long-term use, the old rotating drum can be removed and replaced with a new one simply by unscrewing the limiting screw. This eliminates the need to disassemble and replace the entire anti-deviation structure, greatly simplifying the maintenance process, significantly reducing equipment downtime, lowering maintenance manpower and material costs, ensuring anti-deviation effectiveness and steel plate conveying stability in different processing scenarios, and providing strong support for continuous and efficient production.

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example: Reference Figures 1-5 A steel cutting device with an anti-deviation structure includes an operating machine tool 1. Multiple feeding rollers 101 are uniformly rotated and installed on the inner side of one end of the operating machine tool 1. A drive box 2 is fixedly installed on the side of the operating machine tool 1 near the feeding rollers 101. A hydraulic cylinder 5 is installed on the outer end of the drive box 2. The output end of the hydraulic cylinder 5 extends through into the interior of the drive box 2 and is fixedly installed with a movable plate 6. Multiple connecting rods 7 are hinged on both sides of the movable plate 6. Multiple guide rails 201 are evenly and continuously provided on one side of the machine tool 1. Two slide blocks 3 are slidably installed inside each guide rail 201. A vertical rod 301 is fixedly installed in the middle of each slide block 3. A rotating cylinder 4 is sleeved on the outside of the vertical rod 301. A concave plate 304 is fixedly installed at the end of the slide block 3 away from the vertical rod 301. Multiple connecting rods 7 are hinged to the inner wall of the concave plate 304 on the side away from the movable plate 6.

[0019] Specifically: In actual use, the conveying roller 101 provides conveying power to the steel plate by rotating on its own, driving the steel plate to move towards the cutting area along a preset direction. The hydraulic cylinder 5 can push the movable plate 6 to move through the extension and retraction of its output end. The movable plate 6 can convert the linear driving force of the hydraulic cylinder 5 into the swinging power of the connecting rod 7, realizing the direction transmission of power. The two ends of the connecting rod 7 are respectively hinged to the movable plate 6 and the concave plate 304. After receiving the power transmitted by the movable plate 6, it drives the concave plate 304 to move through its own swing, thereby providing drive for the sliding of the slide block 3.

[0020] The slide block 3 is slidably installed inside the guide rail 201 and is fixedly connected to the vertical rod 301 in the middle. It can move along the guide rail 201 under the drive of the connecting rod 7, and simultaneously drive the vertical rod 301 and the rotating cylinder 4 to move closer to or away from the side of the steel plate, so as to realize the adaptation adjustment of the anti-deviation position. The vertical rod 301 is fixed in the middle of the slide block 3, and the rotating cylinder 4 is sleeved on the outside, providing stable installation support for the rotating cylinder 4 and ensuring that the rotating cylinder 4 can rotate freely around it. The rotating cylinder 4 is sleeved on the outside of the vertical rod 301. When it contacts the side of the steel plate, it can rotate synchronously with the steel plate conveying, forming a lateral limit to prevent deviation of the steel plate, while reducing friction damage to the side of the steel plate.

[0021] When all structures work together, the conveying roller 101 drives the steel plate to be conveyed, the hydraulic cylinder 5 drives the movable plate 6 to move, and the connecting rod 7 drives the slide block 3 to slide along the guide rail 201, so that the rotating drum 4 on the vertical rod 301 fits against the side of the steel plate to form a stable limit. When the steel plate is conveyed, the rotating drum 4 forms rolling friction with the side of the steel plate, which replaces the sliding friction between the existing rigid anti-deviation plate and the steel plate, reduces the frictional damage of the anti-deviation component to the side of the steel plate, completely avoids quality defects such as scratches and curling at the edge of the steel plate, and effectively avoids deviation during the conveying process of the steel plate, providing a guarantee for subsequent precise cutting. It should be noted that: multiple conveying rollers 101 are powered by an external drive motor. The output shaft of the drive motor is connected to the main shaft via a coupling. A drive sprocket is installed on the main shaft at the corresponding position of the conveying roller 101, and a driven sprocket is installed at the end of each conveying roller 101. The drive and driven sprockets are meshed by a transmission chain, driving all the conveying rollers 101 to rotate synchronously. The above-mentioned transmission structure and power configuration related to the drive of the conveying rollers 101 are existing mature technologies and will not be described in detail. A screw hole 302 is provided at the end of the vertical rod 301 away from the slide block 3. The rotating drum 4 is rotatably mounted on the surface of the vertical rod 301. The screw hole 302 is internally threaded with a limit screw 303. Multiple guide rails 201 are connected to the interior of the drive box 2, and the multiple guide rails 201 are respectively located between two adjacent conveying rollers 101. Specifically: In actual use, the limiting screw 303 connected to the internal thread of the screw hole 302 can axially limit the rotating drum 4, preventing the rotating drum 4 from falling off the end of the vertical rod 301 during the rotation of the rotating drum 4 as it is conveyed with the steel plate. At the same time, it ensures the flexibility of the rotating drum 4's rotation, achieving both rolling limit on the side of the steel plate and avoiding displacement of the rotating drum 4 from affecting the anti-deviation effect. Multiple guide rails 201 are connected to the inside of the drive box 2, ensuring that the connecting rod 7 inside the drive box 2 can smoothly extend into the guide rail and connect with the slide block 3, realizing the effective transmission of power from the hydraulic cylinder 5 to the slide block 3. Moreover, the guide rails 201 are located between two adjacent conveying rollers 101, so that the anti-deviation point formed by the slide block 3 driving the vertical rod 301 and the rotating drum 4 can be evenly distributed under the steel plate. At the same time, it avoids mechanical interference to the conveying action of the conveying rollers 101, forming multiple lateral limits on the steel plate, further improving the stability of the steel plate during the conveying process and reducing the risk of deviation.

[0022] Multiple grooves 601 are evenly provided on both sides of the movable plate 6. A shaft 701 is fixedly installed at both ends of the connecting rod 7. One end of the connecting rod 7 is rotatably mounted to the inner wall of the groove 601 via the shaft 701, and the end of the connecting rod 7 away from the movable plate 6 is rotatably mounted to the inner wall of the concave plate 304 via the shaft 701. The shafts 701 fixed at both ends of the connecting rod 7 serve as rotating connectors, allowing one end of the connecting rod 7 to rotate around the inner wall of the groove 601 of the movable plate 6, and the other end to rotate around the inner wall of the concave plate 304. This achieves flexible transmission between the movable plate 6 and the slide block 3, avoiding any issues during power transmission. To ensure smooth anti-deviation adjustment, two limiting posts 8 are fixedly installed inside the drive box 2. Guide holes 801 are respectively opened at both ends of the movable plate 6. The movable plate 6 is slidably installed on the surface of the limiting posts 8 through the two guide holes 801. The limiting posts 8 and the guide holes 801 at both ends of the movable plate 6 are precisely matched to provide rigid guidance for the sliding of the movable plate 6, restricting the movable plate 6 to move only along the axial direction of the limiting posts 8, preventing the movable plate 6 from deviating or tilting due to uneven force, ensuring the stability of the movable plate 6 when driving the connecting rod 7, and laying the foundation for the subsequent precise adjustment of the slide block 3. A frame 9 is fixedly installed on the side of the machine tool 1 away from the feed roller 101. A linear guide rail 901 is fixedly installed on the inner side of the frame 9. A laser cutting device 902 is slidably installed on the surface of the linear guide rail 901. The laser cutting device 902 is connected to the linear guide rail 901 through a slider adapted to the linear guide rail 901. A laser head 903 is fixedly installed at the end of the laser cutting device 902. The linear guide rail 901 fixed on the inner side of the frame 9 provides a directional sliding path for the laser cutting device 902 through the slider adapted to the laser cutting device 902, so that the laser cutting device 902 can move smoothly along the guide rail and achieve precise cutting in conjunction with the stable feeding of the steel plate. The laser head 903 fixed at the end of the laser cutting device 902 serves as a cutting execution component and can cut the steel plate according to preset parameters to complete the cutting operation.

[0023] It should be noted that the laser cutting device 902 slides in conjunction with the linear guide rail 901 via an adapter slider. The slider groove matches the cross-section of the guide rail to ensure smooth sliding. A linear motor or ball screw transmission component external to the linear guide rail 901 can be used. When the ball screw is in operation, the motor drives the screw to rotate, causing the laser cutting device 902 to move along with the nut seat on the screw. The above-mentioned movement principle is a mature existing technology and will not be elaborated further.

[0024] The working principle of this utility model is as follows: In specific use, the steel plate to be cut is first placed on the feeding roller 101 of the operating machine tool 1. After the equipment is started, the feeding roller 101 rotates to drive the steel plate to be conveyed to the cutting area along the preset direction. When it is necessary to adjust the anti-deviation limit position according to the width of the steel plate, the hydraulic cylinder 5 on the outside of the drive box 2 is started. The output end of the hydraulic cylinder 5 pushes the movable plate 6 to slide stably along the limit post 8 inside the drive box 2. During the sliding process of the movable plate 6, the connecting rod 7 hinged to the shaft 701 in the grooves 601 on both sides is simultaneously subjected to force, which in turn pushes the concave plate 304 hinged to the other end of the connecting rod 7 to move. The concave plate 304 then drives the slide block 3 to slide towards or away from each other in the guide rail 201 at the end of the operating machine tool 1.

[0025] Since multiple guide rails 201 are located between two adjacent conveying rollers 101, when the slide block 3 moves, it will synchronously drive the fixed vertical rod 301 and the rotating drum 4 sleeved on the outside of the vertical rod 301 to approach the side of the steel plate until the rotating drum 4 makes light contact with the side of the steel plate, forming a lateral limit on the steel plate; during this process, the rotating drum 4 can rotate freely with the conveying direction of the steel plate, converting the contact friction with the side of the steel plate into rolling friction.

[0026] If the rotating drum 4 becomes worn or damaged after long-term use, simply unscrew the limiting screw 303 in the screw hole 302 at the end of the vertical rod 301 to remove the old rotating drum 4 and replace it with a new one. After replacement, tighten the limiting screw 303 again to restore the anti-deviation function, ensuring that the steel plate always maintains a stable feeding trajectory throughout the entire cutting process and guaranteeing cutting accuracy.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
