Description

Technical Field

[0001] This utility model relates to the field of steel billet diversion in steel rolling, and in particular to a high-speed bar steel diverter. Background Technology

[0002] In the bar production process, the bar separator is an essential piece of equipment. Its main function is to separate continuously conveyed bars according to certain rules for subsequent processing, inspection, or storage. The high-speed bar separator is a device installed at the entrance of the cooling bed of a high-speed bar rolling line. It separates the continuously high-speed running rows of bars one by one according to a set number, forming single streams that do not interfere with each other. This ensures that subsequent fixed-length flying shearing, cooling, and bundling processes do not result in jamming, disorder, or mixed numbers of bars. After separation, it must be used in conjunction with a chain conveyor to gradually reduce the bar speed to the working speed of the bar separator while maintaining a straight state.

[0003] A search revealed a Chinese patent publication number: CN222607546U, which discloses a steel divider that uses a top divider to separate the steel material fed into the machine frame to the left and right sides for feeding. The base can be detached and installed on the machine frame, facilitating later maintenance, replacement, and installation. After the improvement, no accidents occurred with the top divider, and the time to replace the steel divider component was reduced to less than 30 minutes, saving a significant amount of worker time.

[0004] In the above technical solution, the frame base can reduce steel separation accidents. However, the steel bars after separation are transported by the chain bed. When they fall onto the chain bed, there is no buffer function. Due to inertia, the bars are prone to violent collisions, which can cause damage to the surface of the bars and affect product quality. Therefore, a high-speed bar steel separator is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above deficiencies, this utility model provides a high-speed bar separator, which aims to improve the problem that the lack of buffering function in the existing high-speed bar separator leads to increased risk of surface damage due to collisions between bars before conveying them.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a high-speed bar separator, comprising a frame 1, a chain bed 2 disposed on the inner surface of the frame 1, a storage bin 3 disposed on the outer wall of the chain bed 2, a discharge port on the side of the storage bin 3, and a separating wedge disposed inside the storage bin 3, the wedge having a triangular or trapezoidal top, which is inserted into the gap between bars to achieve preliminary separation, for example, dividing the bars into groups of 100. The bars are conveyed in batches through the chain bed 2. The separating wedge is fixed to the top of the inner wall of the storage bin 3, with its triangular / trapezoidal tip pointing downwards. The inclined inner wall of the storage bin 3 allows the bars to roll naturally to form... The gap (the self-alignment of the bars by gravity is a known technique) is filled by steel wedges inserted into the naturally formed gap through a fixed height difference. A mounting frame 6 is fixed to the outer wall of the frame 1. A motor 4 is fixedly connected to the outer wall of the mounting frame 6. A rotating shaft 7 is fixedly connected to the output end of the motor 4. A drive wheel 8 is fixedly connected to the outer wall of the rotating shaft 7. A support shaft 10 is rotatably connected to the inner wall of the frame 1. The support shaft 10 is fixedly connected to the inclined lower end of the guide plate 5. The support shaft 10 passes through the frame 1. A driven wheel 9 is fixedly connected to the outer wall of the support shaft 10. The drive wheel 8 meshes with the driven wheel 9. A guide plate 5 is fixedly connected and is inclined. The inclined angle is switched via the meshing of two sets of gears, providing buffering for the bar stock entering the chain bed 2. A guide groove 11 is provided at the bottom of the guide plate 5, and a guide block 12 is slidably connected to the inner wall of the guide groove 11. Two sets of guide grooves 11 and guide blocks 12 are provided, and the guide grooves 11 and guide blocks 12 are located on opposite sides of the bottom of the guide plate 5. Through the cooperation of the two pairs of supporting columns 14 and supporting cylinders 15, the guide plate 5 is provided with stable support. A mounting plate 13 is hinged to the bottom of the guide block 12. A support column 14 is fixedly connected to the bottom of the mounting plate 13. A slider 16 is fixedly connected to the outer wall of the support column 14. A support cylinder 15 is fixedly connected to the surface of the storage bin 3. The support cylinder 15 is sleeved on the outer wall of the support column 14. A sliding groove 17 is opened on the inner wall of the support cylinder 15. Sliding grooves 17 are opened on both sides of the inner wall of the support cylinder 15. When the support column 14 is raised and lowered, it is guided by the slider 16. The inner wall of the sliding groove 17 is slidably connected to the outer wall of the slider 16. A spring 18 is fixedly connected to the bottom end of the support column 14. The bottom end of the spring 18 is fixedly connected to the inner wall of the support cylinder 15.

[0033] Reference Figures 2-4The inner wall of the support cylinder 15 is fixedly connected to a proportional valve 20 via a pipe. The end of the proportional valve 20 is fixedly connected to an air injection pipe 19, which is a three-way pipe. Both ends of the three-way pipe are connected to two sets of proportional valves 20, and the other end is fixedly connected to the air outlet of the air pump 21. The end of the air injection pipe 19 is fixedly connected to the air pump 21, and the bottom of the air pump 21 is fixedly connected to the outer surface of the frame 1. The spring 18 provides basic elastic support, and the air pressure assists in adapting to variable loads. When the bar impacts the guide plate 5, the support column 14 compresses the spring 18 and sinks, reducing the space inside the support cylinder 15. The proportional valve 20 detects the pressure increase and increases the air injection volume according to the preset ratio. Air is supplied through the air pump 21 to form an air cushion effect to offset the impact force.

[0034] Reference Figure 3 , Figure 5 A collar 22 is fixedly connected to the outer wall of the air pump 21. The collar 22 is located at the air inlet end of the air pump 21. A straight groove 23 is opened through the outer wall of the collar 22. A positioning block 24 is set inside the straight groove 23. The inner wall of the straight groove 23 is adapted to the outer wall of the positioning block 24. When the filter frame 26 is installed, the positioning block 24 and the straight groove 23 are in a cross shape. The positioning block 24 is removed and rotated, which drives the screw 25 into the filter frame 26. The positioning block 24 and the straight groove 23 are in a cross shape. When the positioning block 24 is parallel to the straight groove 23, it can be removed from the straight groove 23 to disassemble the filter frame 26. The outer wall of the positioning block 24 is fixedly connected to the screw 25, and the outer wall of the screw 25 is threadedly connected to the filter frame 26. The filter frame 26 has a threaded hole inside. The outer wall of the filter frame 26 fits against the outer wall of the collar 22. The inner wall of the filter frame 26 is fixedly connected to the filter screen to prevent impurities from falling off the chain bed 2 and affecting the air inlet of the air pump 21.

[0035] Working principle: First, the bars enter the storage bin 3. The top of the steel wedges inside the storage bin 3 is triangular or trapezoidal, which can accurately insert into the gaps between the bars to initially separate them. For example, the bars can be divided into groups of 100, laying the foundation for subsequent batch conveying. The separated bars fall onto the guide plate 5, which is inclined. Its core function is to provide a buffer for the bars to enter the chain bed 2 for conveying, avoiding direct impact on the chain bed 2 and causing damage or unstable conveying. The inclination angle of the guide plate 5 can be flexibly adjusted by the transmission structure driven by the motor 4: When the motor 4 is working, its output end drives the rotating shaft 7 to rotate, and the drive wheel 8 on the outer wall of the rotating shaft 7 rotates accordingly. The driven wheel 9 on the outer wall of the support shaft 10 meshes with the driving wheel 8, which drives the driven wheel 9 to rotate, thereby causing the support shaft 10 to rotate. The guide plate 5, which is fixedly connected to the support shaft 10, will switch its tilt angle to adapt to the buffering requirements of bars of different specifications. During the process of the guide plate 5 carrying the bars, the guide groove 11 at its bottom slides with the guide block 12 to provide guidance for the angle adjustment of the guide plate 5. At the same time, the mounting plate 13 hinged to the bottom of the guide block 12 is connected to the support column 14. The support column 14 is sleeved in the support cylinder 15 on the surface of the storage bin 3. The slider 16 on the outer wall of the support column 14 slides in the groove 17 on the inner wall of the support cylinder 15 to ensure the stable lifting and lowering of the support column 14. The spring 18 at the bottom of the 4th section is in a compressed or stretched state, providing basic elastic support for the guide plate 5 and initially buffering the impact force of the falling bar. To further enhance the stability and buffering effect of the guide plate 5, the equipment is equipped with an auxiliary support system of air pump 21. The air pump 21 is connected to two sets of proportional valves 20 through an air injection pipe 19 (T-connector). The proportional valves 20 are then connected to the inner wall of the support cylinder 15 through pipes. The gas generated by the air pump 21 during operation is delivered to the proportional valves 20 through the air injection pipe 19. The proportional valves 20 can precisely control the amount of gas entering the support cylinder 15, thereby adjusting the air pressure inside the support cylinder 15. The air pressure and the elastic force of the spring 18 work together to provide the support column 14 with a force suitable for the weight of the bar. The supporting force provides more stable buffering when the bar impacts the guide plate 5, preventing the guide plate 5 from being damaged due to excessive force. In addition, the outer wall of the collar 22 at the air inlet end of the air pump 21 is equipped with a filter frame 26. The filter frame 26 is fixed by the cooperation of the positioning block 24 and the straight groove 23 and the screw 25. The filter screen inside the filter frame 26 can filter the air entering the air pump 21, effectively blocking impurities and preventing impurities from entering the air pump 21, the proportional valve 20 or the support cylinder 15 and causing blockage, thus ensuring the stable operation of the air circuit system. After being buffered and guided by the guide plate 5, the bar smoothly enters the chain bed 2. Finally, the chain bed 2 transports the grouped bar to the next process in batches, completing the entire steel sorting and conveying process.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
