Description

Technical Field

[0001] This utility model belongs to the field of guide roller correction technology, specifically an automatic guide roller correction device. Background Technology

[0002] A guide is a device installed before and after the roll pass during the rolling process of profile steel to help the rolled piece enter and exit the roll pass accurately and stably in a predetermined direction and state.

[0003] During the rolling process of structural steel, it is necessary to ensure that the position of the structural steel does not shift. If the position of the structural steel shifts, it may cause uneven rolling pressure in different parts, resulting in a decrease in product quality. At the same time, the position of the structural steel is prone to abnormal friction between its surface and the guide device, causing defects such as surface scratches and wear. The existing guide is not convenient for correcting the structural steel passing through its middle, which can easily lead to a series of adverse effects after the structural steel shifts.

[0004] Therefore, this utility model provides an automatic correction guide roller device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An automatic correction guide roller device of this utility model includes a guide body; a plurality of first guide rollers are rotatably connected to the inner bottom of the guide body; a pair of fixed seats are fixedly connected to the bottom of the guide body; a bidirectional lead screw is rotatably connected to the middle of the pair of fixed seats; a motor is fixedly connected to the side wall of one of the fixed seats; the output end of the motor is fixedly connected to the end of the bidirectional lead screw; a pair of connecting frames are symmetrically threaded to the middle of the bidirectional lead screw; a correction plate is fixedly connected to the top side wall of the connecting frame; a plurality of second guide rollers are rotatably connected to the side wall of the correction plate; and an offset detection component is installed in the middle of the guide body. Through the above structure, when the conveyed steel section deviates in the middle of the guide, the position of the steel section is automatically corrected, reducing a series of adverse effects caused by the steel section deviating.

[0007] Preferably, the offset detection component includes a pair of rotating shafts; the pair of rotating shafts are symmetrically arranged and rotatably connected to the middle of the guide body via torsion springs; a baffle is installed in the middle of the rotating shafts; a turntable is fixedly connected to the bottom of the baffle; a pull rope is fixedly connected to the middle of the turntable; a processing box is fixedly connected to the bottom of the guide body; a pair of sliding rods are slidably connected to the middle of the processing box; one end of the sliding rod is fixedly connected to the end of the pull rope; a spring is fixedly connected to the other end of the sliding rod; the other end of the spring is fixedly connected to the side wall of the processing box; through the above structure, the width parameter of the steel section can be automatically identified, so that a pair of correction plates can be accurately moved to the corresponding position to limit the steel section, making it difficult for gaps to appear between the multiple second guide rollers and the steel section for the steel section to offset, thereby reducing the occurrence of steel section offset.

[0008] Preferably, a support frame is fixedly connected to the top of the rotating shaft; a through groove is provided in the middle of the support frame; a limiting plate is fixedly connected to the top of the baffle; with the above structure, the baffle can be easily replaced when the surface of the baffle is worn to a large extent, thus improving the ease of use of the device.

[0009] Preferably, a third guide roller is rotatably connected to the bottom of the limiting plate; the third guide roller is located at the end of the limiting plate away from the rotating shaft; through the above structure, the sliding friction between the baffle and the steel section can be converted into rolling friction between the third guide roller and the steel section, reducing the replacement frequency of the baffle and reducing the impact on the surface quality of the steel section product.

[0010] Preferably, an elastic membrane sleeve is fixedly connected between the pair of connecting frames; an elastic membrane sleeve is also fixedly connected to the other side of the connecting frame; and the other end of the elastic membrane sleeve is fixedly connected to the side wall of the fixed seat. With the above structure, the occurrence of external impurities falling on the surface of the bidirectional lead screw and causing the pair of connecting frames to move and block is reduced, thereby reducing the occurrence of motor overload damage caused by the connecting frames being difficult to move.

[0011] Preferably, a partition is fixed between a pair of the fixed seats; the partition extends through a pair of connecting frames; the partition is located above the bidirectional lead screw and inside a plurality of elastic membrane sleeves; with the above structure, when the elastic membrane sleeve droops in the middle due to contraction, it will not easily come into contact with the bidirectional lead screw, reducing the occurrence of the elastic membrane sleeve being worn by the rotating bidirectional lead screw or being rolled to the connecting frame as the bidirectional lead screw rotates, thus hindering the movement of the connecting frame.

[0012] Preferably, the plurality of second guide rollers and the plurality of first guide rollers are staggered; the bottom ends of the plurality of second guide rollers are lower than the top ends of the first guide rollers; with the above structure, when the profile steel is thin, the plurality of second guide rollers can still contact the two sides of the profile steel and reduce the wear on the two sides of the profile steel.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The automatic correction guide roller device of this utility model, through the arrangement of guide body, first guide roller, fixed seat, bidirectional screw, motor, connecting frame, correction plate and second guide roller, automatically corrects the position of the steel section when the conveyed steel section deviates in the middle of the guide, thereby reducing a series of adverse effects caused by the steel section deviating.

[0015] 2. The automatic correction guide roller device of this utility model, through the setting of a rotating shaft, baffle, turntable, pull rope, processing box, slide rod and spring, can automatically identify the width parameters of the steel section, so that a pair of correction plates can move accurately to the corresponding position to limit the steel section, making it difficult for gaps to appear between the multiple second guide rollers and the steel section for the steel section to deviate, thereby reducing the occurrence of steel section deviation.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 3As shown, an automatic guide roller device for correcting deviation in this utility model includes a guide body 1; a plurality of first guide rollers 12 are rotatably connected to the bottom inner side of the guide body 1; a pair of fixed seats 13 are fixedly connected to the bottom of the guide body 1; a bidirectional lead screw 14 is rotatably connected to the middle of the pair of fixed seats 13; a motor 15 is fixedly connected to the side wall of one fixed seat 13; the output end of the motor 15 is fixedly connected to the end of the bidirectional lead screw 14; a pair of connecting frames 16 are symmetrically threaded to the middle of the bidirectional lead screw 14; a correction plate 17 is fixedly connected to the top side wall of the connecting frame 16; a plurality of second guide rollers 18 are rotatably connected to the side wall of the correction plate 17; an offset detection component is installed in the middle of the guide body 1; during operation, the steel section will fall onto the plurality of first guide rollers 12 and be drawn from the pair of correction rollers 18. As the steel profile passes between the offset plates 17, it may deviate to one side of the guide body 1. The offset detection component detects the amount of offset of the steel profile inside the guide body 1. Based on the detection result, the motor 15 is started to drive the bidirectional lead screw 14 to rotate. The rotation of the bidirectional lead screw 14 simultaneously drives a pair of connecting frames 16 to move closer or further apart, so that the steel profile is pushed by a correction plate 17 until the steel profile is in the middle of the guide body 1. Multiple first guide rollers 12 and second guide rollers 18 will passively rotate as the contacted steel profile moves, reducing the wear on the surface of the steel profile. Through the above structure, when the conveyed steel profile deviates in the middle of the guide, the position of the steel profile is automatically corrected, reducing a series of adverse effects caused by the steel profile deviating.

[0024] like Figures 1 to 4As shown, the offset detection component includes a pair of rotating shafts 2; the pair of rotating shafts 2 are symmetrically arranged and rotatably connected to the middle of the guide body 1 via torsion springs; a baffle 21 is installed in the middle of the rotating shaft 2; a turntable 22 is fixedly connected to the bottom of the baffle 21; a pull rope 23 is fixedly connected to the middle of the turntable 22; a processing box 24 is fixedly connected to the bottom of the guide body 1; a pair of sliding rods 25 are slidably connected to the middle of the processing box 24; one end of the sliding rod 25 is fixedly connected to the end of the pull rope 23; a spring 26 is fixedly connected to the other end of the sliding rod 25; the other end of the spring 26 is fixedly connected to the side wall of the processing box 24; during operation, when the end of the profile steel enters the guide and moves, the profile steel will push the pair of baffles 21, thereby causing the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 will drive the turntable 22 to rotate, and the rotation of the turntable 22 will cause the pull rope 23 to be wound in the middle of the turntable 22 and drive the sliding rod 25 to slide. When the slide bar 25 slides, the displacement sensor inside the processing box 24 identifies the displacement distance of the slide bar 25. When the profile steel deviates from the guide center, the rotation angle of the pair of rotating shafts 2 will be different, resulting in different displacement distances of the pair of slide bars 25. The processor inside the processing box 24 calculates the width parameter of the profile steel based on the displacement distance of the pair of slide bars 25, thus enabling the pair of straightening plates 17 to move and adjust according to the width parameter of the profile steel, and stably restrict the profile steel at the guide center. Through the above structure, the width parameter of the profile steel can be automatically identified, so that the pair of straightening plates 17 can move accurately to the corresponding position to limit the profile steel, making it difficult for gaps to appear between the multiple second guide rollers 18 and the profile steel for the profile steel to deviate, thereby reducing the occurrence of profile steel deviation.

[0025] like Figure 4 As shown, a support frame 3 is fixedly connected to the top of the rotating shaft 2; a through groove 31 is opened in the middle of the support frame 3; a limiting plate 32 is fixedly connected to the top of the baffle 21; during operation, as the steel section moves between the pair of baffles 21, the pair of baffles 21 will be damaged by friction from the steel section. When the surface damage of the baffle 21 is too large, it will affect the calculation result of the width of the steel section. At this time, the damaged baffle 21 can be removed and a new baffle 21 can be inserted into the through groove 31, so that the limiting plate 32 falls above the support frame 3 to complete the replacement. Through the above structure, the baffle 21 can be easily replaced when the surface wear of the baffle 21 is large, improving the ease of use of the device.

[0026] like Figure 4As shown, a third guide roller 4 is rotatably connected to the bottom of the limiting plate 32; the third guide roller 4 is located at the end of the limiting plate 32 away from the rotating shaft 2; during operation, as the steel section pushes open a pair of baffles 21, the pair of third guide rollers 4 will contact the side wall of the steel section and rotate with the movement of the steel section, thereby reducing the wear on the surface of the steel section and the edge of the baffles 21, so that the baffles 21 will only be worn when they come into contact with the end of the steel section. Through the above structure, the sliding friction between the baffles 21 and the steel section can be converted into rolling friction between the third guide roller 4 and the steel section, reducing the replacement frequency of the baffles 21 and reducing the impact on the surface quality of the steel section product.

[0027] like Figure 3 As shown, an elastic membrane sleeve 5 is fixed between a pair of connecting frames 16; an elastic membrane sleeve 5 is also fixed to the other side of the connecting frame 16; and the other end of this elastic membrane sleeve 5 is fixed to the side wall of the fixed seat 13. During operation, as the pair of connecting frames 16 moves, multiple elastic membrane sleeves 5 will correspondingly contract or extend, and continuously block external impurities, making it difficult for external impurities to pass through the elastic membrane sleeve 5 and fall onto the surface of the bidirectional lead screw 14. Through the above structure, the occurrence of external impurities falling onto the surface of the bidirectional lead screw 14 and causing the pair of connecting frames 16 to move and block the movement can be reduced, thereby reducing the occurrence of motor 15 overload damage caused by the difficulty in moving the connecting frame 16.

[0028] like Figure 3 As shown, a partition 6 is fixed between a pair of fixed seats 13; the partition 6 is disposed through a pair of connecting frames 16; the partition 6 is located above the bidirectional lead screw 14 and inside multiple elastic membrane sleeves 5; during operation, as the elastic membrane sleeves 5 contract, the middle part of the elastic membrane sleeves 5 will become loose and droop. By setting the partition 6, when the middle part of the elastic membrane sleeves 5 droops due to contraction, it will not easily come into contact with the bidirectional lead screw 14, reducing the occurrence of the elastic membrane sleeves 5 being worn by the rotating bidirectional lead screw 14 or being rolled to the connecting frame 16 as the bidirectional lead screw 14 rotates, thus hindering the movement of the connecting frame 16.

[0029] like Figure 1 As shown, the multiple second guide rollers 18 and the multiple first guide rollers 12 are staggered; the bottom of the multiple second guide rollers 18 is lower than the top of the first guide rollers 12; with the above structure, when the steel section is thin, the multiple second guide rollers 18 can still contact the two sides of the steel section and reduce the wear on the two sides of the steel section.

[0030] During operation, the steel profile falls onto multiple first guide rollers 12 and passes between a pair of straightening plates 17. At this time, the steel profile may deviate to one side of the guide body 1. The offset detection component detects the amount of offset of the steel profile inside the guide body 1, and then, based on the detection result, starts the motor 15 to drive the bidirectional lead screw 14 to rotate. The rotation of the bidirectional lead screw 14 simultaneously causes a pair of connecting frames 16 to move closer or further apart, so that the steel profile is pushed by a straightening plate 17 until it is in the middle position of the guide body 1. The multiple first guide rollers 12 and second guide rollers 18 will passively rotate as the contacting steel profile moves, reducing the deviation. The wear on the surface of the steel profile causes the end of the steel profile to push a pair of baffles 21 as it enters the guide and moves, thus causing the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 drives the turntable 22 to rotate, which causes the pull rope 23 to wind up in the middle of the turntable 22 and drive the slide rod 25 to slide. When the slide rod 25 slides, the displacement sensor inside the processing box 24 will identify the displacement distance of the slide rod 25. When the steel profile deviates from the center of the guide, the rotation angle of the pair of rotating shafts 2 will be different, resulting in different displacement distances of the pair of slide rods 25. The processor inside the processing box 24 detects the displacement of the pair of slide rods 25. The distance is calculated to easily obtain the width parameters of the steel section, allowing a pair of straightening plates 17 to move and adjust according to the width parameters of the steel section, stabilizing the steel section at the center of the guide. As the steel section moves between the pair of baffles 21, the baffles 21 will be damaged by friction from the steel section. When the surface damage of the baffles 21 is too large, it will affect the calculation result of the steel section width. At this time, the damaged baffles 21 can be removed and a new baffle 21 can be inserted into the through groove 31, so that the limiting plate 32 falls above the bearing frame 3 to complete the replacement. As the steel section pushes open the pair of baffles 21, a pair of third guide rollers 4 will... The side wall of the steel profile contacts and rotates as the steel profile moves, thereby reducing the wear on the surface of the steel profile and the edge of the baffle 21. This ensures that the baffle 21 is only worn when it comes into contact with the end of the steel profile. As a pair of connecting frames 16 move, multiple elastic diaphragms 5 will contract or extend accordingly, continuously blocking external impurities. This makes it difficult for external impurities to pass through the elastic diaphragms 5 and fall onto the surface of the bidirectional lead screw 14. As the elastic diaphragms 5 contract, the middle part of the elastic diaphragms 5 will become loose and droop. With the partition 6, the middle part of the elastic diaphragms 5 will not easily contact the bidirectional lead screw 14 when it droops due to contraction.
