Description

Technical Field

[0001] This utility model relates to the field of flat steel processing technology, specifically to a variable-pitch flat steel rolling guide assembly. Background Technology

[0002] Currently, a rolling mill is a piece of equipment used to process steel. It feeds heated steel into the rolling mill for rolling, and this requires the use of guide devices to guide and move the steel to ensure that the steel is accurately fed into the rolling mill for processing. The accuracy of the guide device will directly affect the quality of the processed steel.

[0003] A search revealed a utility model patent with Chinese patent publication number CN223128925U, which discloses a flat steel rolling inlet guide assembly, including a base plate. The upper surface of the base plate is fixedly connected to a support plate, and the upper surface of the support plate is rotatably connected to one end of a connecting shaft. The outer side of the connecting shaft is fixedly connected to a side plate. A rectangular groove is formed on the upper surface of the base plate, and the inside of the rectangular groove is rotatably connected to one end of a threaded rod. A moving block is provided on the outer side of the threaded rod, and the side of the moving block is hinged to one end of a hinge plate. The side of the moving block is fixedly connected to one end of a connecting plate. The bottom surface of the side plate is fixedly connected to a slider, and the side surface of the side plate is fixedly connected to a mounting plate.

[0004] The above-mentioned device adjusts the spacing of the guide rollers by adjusting the rotation of the movable end of the side plate. During operation, the stress on the movable end is transmitted to the hinge plate. Since the stress generated by the steel during the conveying process is relatively large, the hinge plate will inevitably deform, which will affect the processing accuracy and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a variable-pitch flat steel rolling guide assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a variable-pitch flat steel rolling guide assembly, comprising a housing, a guide roller assembly installed inside the housing, the guide roller assembly including a bidirectional lead screw two fixedly connected inside the housing, the bidirectional lead screw two being horizontally arranged and located at a corner position near the outside of the top of the housing, a movable seat being threadedly connected to the threaded ends of the bidirectional lead screw two, a vertically arranged reinforcing sleeve being hinged to the bottom of the movable seat, two horizontally arranged slide rails two being fixedly connected inside the housing, and the two slide rails two being located on both sides of the bidirectional lead screw two, the two movable seats being slidably sleeved outside the two slide rails two, a reinforcing structure being installed at the bottom of the movable seat, a variable-pitch structure being installed at the bottom of the housing, the reinforcing structure including two extension plates and two pins, the variable-pitch structure including a bidirectional lead screw one, two mounting seats, two slide rails one and two guide roller bodies.

[0007] The top and bottom ends of the mounting base for the guide roller body can be fixed simultaneously, ensuring sufficient stability of the guide roller body during operation and facilitating machining accuracy. By rotating the double-acting screw, the two mounting bases connected to it by the knob can be moved towards each other along the two slide rails, so that the guide roller body fixed on the outside is in contact with the round steel billet. Then, the positions of the two moving bases are adjusted in the same way so that the reinforcing sleeves at the bottom of the two bases can be fitted onto the outside of the mounting base. At this time, the top of the mounting base can also be supported, making the guide roller body installed on it more stable during operation.

[0008] As a further preferred embodiment of this technical solution, the two extension plates are respectively fixedly connected to the outer wall of one side of the two movable seats, the two pins are respectively slidably inserted into the inside of the two extension plates, and the inside of the two reinforcing sleeves is provided with insertion holes that are compatible with the pins.

[0009] As a further preferred embodiment of this technical solution, the bidirectional lead screw is rotatably connected inside the housing, and the bidirectional lead screw is located at a corner position near the outside of the bottom of the housing. The two mounting seats are respectively threaded to the threads at both ends of the bidirectional lead screw. The two slide rails are fixedly connected inside the housing, and the two slide rails are respectively located on both sides of the bidirectional lead screw. The two mounting seats are slidably connected to the outside of the two slide rails. The two guide roller bodies are rotatably connected to the outer wall of the side of the two mounting seats that are close to each other.

[0010] As a further preferred embodiment of this technical solution, a feed hopper is fixedly installed on the outer wall of the housing away from the guide roller assembly, and a cleaning assembly is installed between the feed hopper and the guide roller assembly.

[0011] As a further preferred embodiment of this technical solution, the cleaning assembly includes a mounting bracket fixedly connected to the inner wall of the bottom of the housing. A horizontally arranged cleaning ring is rotatably connected inside the mounting bracket. A motor is fixedly installed on the top of the outer wall of one side of the mounting bracket. A gear is coaxially fixed to the output end of the motor. A toothed ring is coaxially fixed to the outer wall of the circumference of the cleaning ring. The gear meshes with the toothed ring. Two parallel wire brushes are rotatably connected inside the cleaning ring.

[0012] As a further preferred embodiment of this technical solution, a first bevel gear is coaxially fixed at the same end of each of the two wire brushes. Two vertically arranged mounting plates are fixedly connected to the outer circumference of the cleaning ring, and a second gear is rotatably connected inside each of the two mounting plates. A second bevel gear is coaxially fixed to each of the two second gears, and the two second bevel gears face opposite directions and mesh with the two first bevel gears respectively. A vertically arranged toothed ring is fixedly connected to the inner wall of the bottom of the housing, and both of the two second gears mesh with the toothed ring.

[0013] During operation, the motor drives gear one to rotate, which in turn drives gear ring one to rotate. Gear ring one then drives cleaning ring to rotate, causing two wire brushes fixed inside the cleaning ring to revolve around the steel billet. The wire brushes clean the steel billet. As the cleaning ring rotates, gear two meshes with gear ring two and rotates on its own axis. Gear two drives the second bevel gear connected to it to rotate, and the second bevel gear, through which it meshes with the first bevel gear, drives the wire brushes to rotate. Therefore, the wire brushes rotate on their own axis while revolving around the steel billet, sweeping the impurities removed from the steel billet to a fixed direction, thus preventing the impurities from moving with the steel billet and being rolled, which helps to ensure the cleaning effect.

[0014] As a further preferred embodiment of this technical solution, two horizontally arranged connecting blocks are fixedly connected to the lower part of the outer walls at both ends of the housing, and each of the four connecting blocks has a connecting hole inside.

[0015] This utility model provides a variable-pitch flat steel rolling guide assembly, which has the following beneficial effects:

[0016] (1) By setting the guide roller assembly, the top and bottom ends of the mounting seat for mounting the guide roller body can be fixed at the same time, thereby ensuring that the guide roller body is stable enough during operation, which is conducive to ensuring processing accuracy. By turning the knob to drive the double-acting screw to rotate, the double-acting screw can drive the two mounting seats connected to it to move towards each other along the two slide rails, so that the guide roller body fixed on the outside is in contact with the round steel billet. Then, adjust the position of the two moving seats in the same way so that the reinforcing sleeves at the bottom of the two can be fitted onto the outside of the mounting seat. At this time, the top of the mounting seat can also be supported, making the guide roller body installed on it more stable during operation.

[0017] (2) By setting up a cleaning component, when the present invention is working, the motor is started to drive the first gear to rotate. The first gear drives the first gear ring to rotate through meshing. The first gear ring drives the cleaning ring to rotate. The two wire brushes fixed inside the cleaning ring will revolve around the steel billet. The wire brushes can clean the steel billet. When the cleaning ring rotates, the second gear will mesh with the second gear ring and rotate on its own axis. The second gear drives the second bevel gear connected to it to rotate. The second bevel gear drives the wire brush to rotate through the first bevel gear meshing with it. Therefore, the wire brush rotates on its own axis while revolving. The impurities cleaned from the steel billet will be swept to a fixed direction, thereby preventing the impurities from moving with the steel billet and being rolled. This is conducive to ensuring the cleaning effect. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 4 As shown, in this embodiment, a variable-pitch flat steel rolling guide assembly includes a housing 1. A guide roller assembly 4 is installed inside the housing 1. The guide roller assembly 4 includes a bidirectional lead screw 405 fixedly connected inside the housing 1. The bidirectional lead screw 405 is horizontally arranged and located at a corner position near the outside of the top of the housing 1. A movable seat 407 is threaded to both ends of the bidirectional lead screw 405. A vertically arranged reinforcing sleeve 408 is hinged to the bottom of the movable seat 407. Two horizontally arranged slide rails 406 are fixedly connected inside the housing 1, and the two slide rails 406 are located on both sides of the bidirectional lead screw 405. The two movable seats 407 are slidably sleeved outside the two slide rails 406. A reinforcing structure is installed at the bottom of the movable seat 407. A variable-pitch structure is installed at the bottom of the housing 1. The reinforcing structure includes two extension plates 409 and two pins 410. The variable-pitch structure includes a bidirectional lead screw 401, two mounting seats 402, two slide rails 403, and two guide roller bodies 404.

[0025] Two extension plates 409 are fixedly connected to the outer wall of one side of two movable seats 407 respectively, and two pins 410 are slidably inserted into the inside of the two extension plates 409 respectively. The two reinforcing sleeves 408 are each provided with a hole that matches the pin 410.

[0026] The first bidirectional lead screw 401 is rotatably connected inside the housing 1, and the first bidirectional lead screw 401 is located at a corner of the bottom of the housing 1 near the outside. The two mounting seats 402 are threadedly connected to the threads at both ends of the first bidirectional lead screw 401. The two slide rails 403 are fixedly connected inside the housing 1, and the two slide rails 403 are located on both sides of the first bidirectional lead screw 401. The two mounting seats 402 are slidably connected to the outside of the two slide rails 403. The two guide roller bodies 404 are rotatably connected to the outer wall of the side of the two mounting seats 402 that are close to each other. The thread helix angle of the external threads of the first bidirectional lead screw 401 and the second bidirectional lead screw 405 is less than the equivalent friction angle.

[0027] As the usage time increases, the surface of the guide roller body 404 becomes worn. First, remove the restriction on the top of the mounting base 402 and pull the pin 410 out of the extension plate 409. At this time, the reinforcing sleeve 408 will no longer be restricted. Then, push the movable end of the reinforcing sleeve 408 upward so that it is no longer fitted on the top of the mounting base 402. Then, reinsert the pin 410 to block the reinforcing sleeve 408. Drive the double-acting screw 401 to rotate by the knob. The double-acting screw 401 can drive the two mounting bases 402 connected to it to move towards each other along the two slide rails 403, so that the guide roller body 404 fixed on the outside is in contact with the round steel billet. Then, adjust the position of the two moving bases 407 in the same way so that the reinforcing sleeves 408 at the bottom of the two can be fitted on the outside of the mounting base 402. At this time, the top of the mounting base 402 can also be supported, making the guide roller body 404 installed on it more stable during operation.

[0028] like Figure 2 and Figure 3 As shown, a feed hopper 2 is fixedly installed on the outer wall of the housing 1 away from the guide roller assembly 4, and a cleaning assembly 5 is installed between the feed hopper 2 and the guide roller assembly 4.

[0029] The cleaning component 5 includes a mounting bracket 501 fixedly connected to the inner wall of the bottom of the housing 1. A horizontally arranged cleaning ring 502 is rotatably connected inside the mounting bracket 501. A motor 506 is fixedly installed on the top of the outer wall of one side of the mounting bracket 501. A gear 505 is coaxially fixed to the output end of the motor 506. A toothed ring 504 is coaxially fixed to the outer circumference of the cleaning ring 502. The gear 505 meshes with the toothed ring 504. Two parallel wire brushes 503 are rotatably connected inside the cleaning ring 502.

[0030] Two wire brushes 503 are each coaxially fixed with a first bevel gear 507 at the same end. Two vertically arranged mounting plates are fixedly connected to the outer circumference of the cleaning ring 502, and gears 508 are rotatably connected inside the two mounting plates. Each of the two gears 508 is coaxially fixed with a second bevel gear, and the two second bevel gears face opposite directions and mesh with the two first bevel gears 507 respectively. A vertically arranged toothed ring 509 is fixedly connected to the inner wall of the bottom of the housing 1, and both gears 508 mesh with the toothed ring 509.

[0031] The starting motor 506 drives gear 505 to rotate, which in turn drives gear ring 504 to rotate. Gear ring 504 drives cleaning ring 502 to rotate, and two wire brushes 503 fixed inside cleaning ring 502 will revolve around the steel billet. The wire brushes 503 can clean the steel billet. When cleaning ring 502 rotates, gear 508 will mesh with gear ring 509 and rotate on its own axis. Gear 508 drives the second bevel gear connected to it to rotate. The second bevel gear drives the wire brushes 503 to rotate through the first bevel gear 507 it meshes with. Therefore, the wire brushes 503 rotate on their own axis while revolving around the steel billet. The impurities cleaned from the steel billet will be swept to a fixed direction, thereby preventing the impurities from moving with the steel billet and being rolled, which helps to ensure the cleaning effect.

[0032] like Figure 1 and Figure 2 As shown, two horizontally arranged connecting blocks 3 are fixedly connected to the lower part of the outer wall at both ends of the housing 1, and each of the four connecting blocks 3 has a connecting hole. The connecting parts can be connected and fixed to the external equipment by passing through the connecting holes of the connecting blocks 3.

[0033] This utility model provides a variable-spacing flat steel rolling guide assembly, the specific working principle of which is as follows:

[0034] During operation, as the device is used over time, the surface of the guide roller body 404 becomes worn. First, remove the restriction on the top of the mounting base 402 and pull the pin 410 out of the extension plate 409. At this point, the reinforcing sleeve 408 will no longer be restricted. Then, push the movable end of the reinforcing sleeve 408 upwards so that it is no longer fitted onto the top of the mounting base 402. Next, reinsert the pin 410 to block the reinforcing sleeve 408. Drive the double-acting screw 401 to rotate via the knob. The double-acting screw 401 will then drive the two mounting bases 402, which are threaded to it, to move towards each other along the two slide rails 403, thus fixing them externally. The guide roller body 404 is in contact with the circular steel billet. The positions of the two moving seats 407 are adjusted in the same way so that the reinforcing sleeves 408 at the bottom of the two can be fitted onto the outside of the mounting seat 402. At this time, the top of the mounting seat 402 can also be supported, making the guide roller body 404 installed on it more stable during operation, and preventing the structure from failing to operate normally due to the difference in precision between the two lead screws. The pin 410 is pulled out so that the reinforcing sleeve 408 is flipped downwards and fitted onto the top of the mounting seat 402. Finally, the pin 410 is pushed to enter the reinforcing sleeve 408 to reinforce it.

[0035] During operation, the starting motor 506 drives gear 505 to rotate. Gear 505, through meshing, drives gear ring 504 to rotate. Gear ring 504 drives cleaning ring 502 to rotate. Two wire brushes 503 fixed inside cleaning ring 502 will revolve around the steel billet, thus cleaning the steel billet. When cleaning ring 502 rotates, gear 508 meshes with gear ring 509 and rotates on its own axis. Gear 508 drives the second bevel gear connected to it to rotate. The second bevel gear, through meshing with the first bevel gear 507, drives the wire brushes 503 to rotate. Therefore, the wire brushes 503 rotate on their own axis while revolving around the steel billet. The impurities cleaned from the steel billet will be swept to a fixed direction, thus preventing the impurities from moving with the steel billet and being rolled, which helps to ensure the cleaning effect.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
