Description

Technical Field

[0001] This invention relates to the field of six-roll mill technology, and in particular to a limiting device for preventing the lateral movement of the turning roll. Background Technology

[0002] Six-roll mills are generally used for cold rolling of strip steel. The most widely used six-roll mill model is the HC six-roll mill or its improved version. The characteristics of this model are: the work roll has positive and negative bending functions, the intermediate roll has positive bending and roll shifting functions; the intermediate roll bending device can shift along the axial direction of the roll.

[0003] The single-stand six-roll cold rolling mill is suitable for rolling various metal materials such as carbon steel, silicon steel, and stainless steel. It is currently the mainstream rolling mill model that is widely used. The six-roll single-stand reversible rolling mill has steering rollers at both the exit and the inlet, located between the inlet / outlet coiler and the stand, and installed behind the strip rolls. Its main function is to clamp and deflect the strip.

[0004] In daily production, after the force is decomposed due to the turning action of the guide roller, there is a horizontal component force towards the rolling mill. This force pushes the guide roller to move laterally. After the guide roller moves laterally, its horizontal deviation will cause the wrap angle to be inconsistent, resulting in adverse effects such as measurement error of the strip roll, strip shape difference, and strip breakage.

[0005] Therefore, the present invention provides a limiting device for preventing lateral displacement of the steering roller. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problem that after the force decomposition of the steering action of the steering roller in the prior art, there is a horizontal component force toward the rolling mill, which causes the steering roller to shift laterally.

[0007] To solve the above-mentioned technical problems, the present invention provides a limiting device for preventing the lateral movement of the steering roller, including a six-roll mill frame. Multiple bearing seats are fixedly connected within the six-roll mill frame. A steering roller body is rotatably connected between adjacent bearing seats. The adjacent steering roller bodies are used for conveying and steering the strip steel. Fastening bolts are provided on the sidewalls of the bearing seats to secure them within the six-roll mill frame. Each bearing seat has a limiting E-frame installed on its sidewall. The side of the limiting E-frame away from the bearing seat is installed within the six-roll mill frame. A limiting mechanism is provided on one side of the limiting E-frame to prevent the steering roller from lateral movement during operation. It should be noted that before installation, the six-roll mill must first undergo precision testing to ensure that the positions of all rolls are within the standard range relative to the shape roll (the shape roll position is used as a reference during testing). Simultaneously, it must be ensured that the steering roller, shape roll, tension roll, pressure roll, and all other rolls within the mill are horizontally and vertically aligned.

[0008] In one embodiment of the present invention, the limiting mechanism includes a limiting round rod installed on the side wall of the limiting E-type frame. A limiting frame is fixedly connected to the six-roller single frame at the corresponding position of the limiting round rod. The end of the limiting round rod away from the limiting E-type frame passes through the limiting frame. Two circular heads are fixedly connected to the outer wall of the limiting round rod. Two arc grooves are opened in the limiting frame. The ends of the circular heads away from the limiting round rod are disposed in the arc grooves.

[0009] In one embodiment of the present invention, an elastic frame is fixedly connected to the inner wall of the limiting frame. The side of the elastic frame away from the inner wall of the limiting frame is connected to the end of the limiting round rod. The end of the round head near the arc groove is arc-shaped. During operation, if the lateral force on the strip is too large when it turns, that is, the bearing seat and the limiting E-type frame deviate from their initial positions, the limiting E-type frame will squeeze the limiting round rod on the other side. The round head on the outer wall of the limiting round rod will disengage from the arc groove and squeeze the elastic frame. After one strip clamping is completed, the main body of the steering roller and the bearing seat are no longer under force, that is, the elastic frame is no longer under the squeezing force. When the elastic frame returns to its initial state, the elastic frame will drive the limiting round rod to return to its initial position. That is, the round head on the outer wall of the limiting round rod will be stuck in the arc groove again. Since all the rolls have been precision tested in the initial state and all the roll positions are within the standard range of the plate roll position, when the round head is stuck in the arc groove again, the bearing seat and the main body of the steering roller will return to their initial positions, ensuring the forming quality of the strip.

[0010] In one embodiment of the present invention, two limiting grooves are provided in the limiting frame, and two columnar rods are fixedly connected to the outer wall of the limiting round rod. The columnar rods are slidably connected in the limiting grooves, and the shape of the columnar rods matches the shape of the limiting grooves. During operation, when the limiting round rod moves due to excessive force, the limiting round rod will drive the columnar rods to move in the limiting grooves. Under the mutual limiting of the columnar rods and the limiting grooves, it is convenient for the subsequent round head to be locked in the arc groove again, thereby facilitating the turning and clamping of the strip by the main body of the turning roller.

[0011] In one embodiment of the present invention, the circular head is made of elastic rubber, and the outer wall of the arc groove is provided with rounded corners; during operation, since the circular head is made of elastic rubber, it can be easily locked in the arc groove and removed from the arc groove.

[0012] In one embodiment of the present invention, a mounting frame is fixedly connected to the outer wall of the limiting E-type frame, and a plurality of electric push rods are mounted on the upper surface of the mounting frame. Each electric push rod has a support frame fixedly connected to its telescopic end, and a guide roller is rotatably connected inside each support frame.

[0013] In one embodiment of the present invention, each of the support frames is provided with a rotating rod adapted to the guide roller, and the outer wall of the guide roller is fitted with a rubber sleeve; during operation, the rubber sleeve can remove burrs from the side wall of the strip under the guidance of the guide roller, and can also protect the strip.

[0014] In one embodiment of the present invention, a plurality of sliding frames are fixedly connected inside the mounting frame, and the plurality of sliding frames and electric push rods are arranged in a one-to-one correspondence. The telescopic end of the electric push rod is fixedly connected to a slide rod, and the bottom of the slide rod is slidably connected inside the sliding frame. During operation, when the telescopic end of the electric push rod drives the support frame and the guide roller to move, the telescopic end of the electric push rod will simultaneously drive the slide rod to move inside the sliding frame, thereby facilitating the movement of the guide roller to the strip side and facilitating its guidance of the strip.

[0015] In one embodiment of the present invention, the bottom of the slide rod and the sliding frame are adapted to each other, and a ball bearing is rotatably connected at the contact position between the bottom of the slide rod and the sliding frame. During operation, when the strip steel is clamped and turned by the guide roller, the strip steel will simultaneously exert a certain pressure on the guide roller. Under the interaction of the slide rod and the sliding frame, it can be ensured that the guide roller always guides and limits the strip steel, that is, the problem of the guide roller being misaligned with the strip steel is avoided.

[0016] In one embodiment of the present invention, two limiting round rods are provided and are arranged symmetrically with respect to the limiting E-type frame. The limiting E-type frame is connected to the bearing seat base plate by welding and bolts.

[0017] The technical solution of the present invention has the following advantages compared with the prior art:

[0018] The present invention discloses a limiting device for preventing lateral movement of a steering roller. When the steering roller body and its connected bearing housing are subjected to the steering force of the strip and a lateral force in another horizontal direction, a limiting E-frame and a limiting mechanism are installed on one side of the steering roller body and the bearing housing. This limiting E-frame and limiting mechanism serve to limit and fix the steering roller body, preventing it from continuing to move after being subjected to lateral force. This design ensures that the position of the steering roller body remains unchanged for a long time, reducing the cost of mill precision testing. It also avoids the problems caused by the horizontal deviation of the steering roller body after lateral movement, which can lead to inconsistent wrap angles, resulting in errors in strip roll measurement, strip shape differences, and strip breakage.

[0019] The present invention discloses a limiting device for preventing lateral displacement of the steering roller. When the elastic frame is no longer subjected to compressive force, it will drive the limiting round rod to return to its initial position after the elastic frame returns to its initial state. That is, the round head on the outer wall of the limiting round rod will be stuck in the arc groove again. Since all the rolls have been precision tested in the initial state and all the roll positions are within the standard range of the plate roll position, the bearing seat and the main body of the steering roller will return to their initial positions when the round head is stuck in the arc groove again, thus ensuring the forming quality of the strip steel.

[0020] The present invention discloses a limiting device for preventing lateral displacement of the steering roller. By controlling electric push rods at different positions, the telescopic ends of the electric push rods drive the support frame and guide rollers to move closer to the side wall of the strip, so that the guide rollers at different positions come into contact with the outer wall of the strip. That is, during the turning process, under the limiting of the guide rollers, the squeezing force of the strip on the steering roller can be reduced, which is beneficial to the clamping and turning of the strip.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0032] Reference Figures 1 to 8 As shown in the figure, the limiting device for preventing lateral movement of the steering roller according to an embodiment of the present invention includes a six-roller single frame 1. A plurality of bearing seats 2 are fixedly connected inside the six-roller single frame 1. A steering roller body 3 is rotatably connected between adjacent bearing seats 2. The adjacent steering roller bodies 3 are used for conveying and steering the strip steel. Fastening bolts 201 are provided on the side wall of the bearing seat 2 to reinforce the bearing seat 2 in the six-roller single frame 1. Each bearing seat 2 is equipped with a limiting E-type frame 4 on its side wall. The side of the limiting E-type frame 4 away from the bearing seat 2 is installed in the six-roller single frame 1. A limiting mechanism is provided on one side of the limiting E-type frame 4 to prevent the steering roller from lateral movement during operation.

[0033] During operation, the guide roller body 3 is installed at the outlet and inlet of the six-roll single stand 1, that is, between the inlet / outlet coiler and the stand, and is installed behind the strip roll of the six-roll single stand 1. This installation method is existing technology and will not be described in detail in this embodiment. Then, the strip is fed along the upper and lower guide roller bodies 3, transporting the strip to the pressure rolls of the six-roll mill. The pressure rolls at different positions cold-roll the strip to make the strip surface smooth, flat, and to form the required dimensions. This cold-rolling method is existing technology and will not be described in detail in this embodiment. When the strip is fed and turned along the guide roller body 3, the guide roller body 3 and... When the bearing housing 2 connected to it is subjected to the turning force of the strip and the lateral component force in another horizontal direction, a limiting E-type frame 4 and a limiting mechanism are set on one side of the turning roll body 3 and the bearing housing 2. The limiting E-type frame 4 and the limiting mechanism play a limiting and fixing role, which can prevent the turning roll body 3 from continuing to move after being subjected to lateral force. Through this design, the position of the turning roll body 3 can be guaranteed not to change for a long time, which can reduce the cost of mill accuracy inspection, and also avoid the problem that the horizontal deviation of the turning roll body 3 after lateral movement will cause inconsistent wrap angle, resulting in plate roll measurement error, strip shape difference, strip breakage and other adverse effects.

[0034] It should be noted that before installation, the six-roll mill must first undergo precision testing to ensure that the positions of all rolls are within the standard range when the plate roll position is used as a reference during the plate roll test. At the same time, it must be ensured that the horizontal and vertical alignment of the guide roll, plate roll, tension roll, pressure roll, and all other rolls in the mill is guaranteed.

[0035] The limiting mechanism includes a limiting round rod 5 installed on the side wall of the limiting E-type frame 4. A limiting frame 6 is fixedly connected to the six-roller single frame 1 at the corresponding position of the limiting round rod 5. The end of the limiting round rod 5 away from the limiting E-type frame 4 passes through the limiting frame 6. Two circular heads 501 are fixedly connected to the outer wall of the limiting round rod 5. Two arc grooves 7 are opened in the limiting frame 6. The ends of the circular heads 501 away from the limiting round rod 5 are set in the arc grooves 7.

[0036] In the initial state, the circular head 501 is in the arc groove 7. During operation, after the steering roller body 3 and the bearing seat 2 connected to it are subjected to the steering force of the strip and another horizontal component force, part of the horizontal component force will be blocked by the limiting E-type frame 4. Moreover, under the limiting compression of the limiting circular rod 5, the limiting E-type frame 4 can be ensured to be in the initial position, improving the limiting of the bearing seat 2 by the limiting E-type frame 4, which facilitates the steering and clamping of the strip.

[0037] An elastic frame 8 is fixed to the inner wall of the limiting frame 6. The side of the elastic frame 8 away from the inner wall of the limiting frame 6 is connected to the end of the limiting round rod 5. The end of the round head 501 near the arc groove 7 is arc-shaped. During operation, if the lateral force on the strip is too large when it turns, that is, the bearing seat 2 and the limiting E-type frame 4 deviate from their initial positions, the limiting E-type frame 4 will squeeze the limiting round rod 5 on the other side. The round head 501 on the outer wall of the limiting round rod 5 will disengage from the arc groove 7 and squeeze the elastic frame 8. After one strip clamping is completed, the main steering roller... Body 3 and bearing seat 2 are no longer under force, that is, elastic frame 8 is no longer under compressive force. When elastic frame 8 returns to its initial state, elastic frame 8 will drive the limiting round rod 5 to return to its initial position. That is, the round head 501 on the outer wall of the limiting round rod 5 will be stuck in the arc groove 7 again. Since all the rolls have been precision tested in the initial state and all the roll positions are within the standard range, when the round head 501 is stuck in the arc groove 7 again, bearing seat 2 and the main body 3 of the guide roller will return to their initial positions, ensuring the forming quality of the strip steel.

[0038] Two limiting grooves 9 are provided in the limiting frame 6. Two column rods 10 are fixed to the outer wall of the limiting round rod 5. The column rods 10 are slidably connected in the limiting grooves 9. The shape of the column rods 10 matches the shape of the limiting grooves 9. During operation, when the limiting round rod 5 moves due to excessive force, the limiting round rod 5 will drive the column rods 10 to move in the limiting grooves 9. Under the mutual limiting of the column rods 10 and the limiting grooves 9, it is convenient for the subsequent round head 501 to be locked in the arc groove 7 again, thereby facilitating the turning and clamping of the strip by the turning roller body 3.

[0039] The circular head 501 is made of elastic rubber, and the outer wall of the arc groove 7 is provided with rounded corners. During operation, since the circular head 501 is made of elastic rubber, it can be easily inserted into the arc groove 7 and removed from the arc groove 7.

[0040] The outer wall of the limiting E-type frame 4 is fixedly connected to a mounting frame 11. Multiple electric push rods 12 are mounted on the upper surface of the mounting frame 11. Each electric push rod 12 has a support frame 13 fixedly connected to its telescopic end. Each support frame 13 has a guide roller 14 rotatably connected inside it. During operation, when the strip is being clamped and turned, by controlling the electric push rods 12 at different positions, the telescopic ends of the electric push rods 12 drive the support frame 13 and the guide roller 14 to move closer to the side wall of the strip, so that the guide rollers 14 at different positions contact the outer wall of the strip. That is, during the turning process, under the limitation of the guide rollers 14, the squeezing force of the strip on the turning roller body 3 during turning can be reduced, which is beneficial to the clamping and turning of the strip.

[0041] Each of the support frames 13 is provided with a rotating rod adapted to the guide roller 14. The outer wall of the guide roller 14 is fitted with a rubber sleeve. During operation, the rubber sleeve can remove burrs from the side wall of the strip under the guidance of the guide roller 14, and also protect the strip.

[0042] Multiple sliding frames 15 are fixedly connected inside the mounting frame 11. The multiple sliding frames 15 and electric push rods 12 are arranged in a one-to-one correspondence. The telescopic end of the electric push rod 12 is fixedly connected to a slide rod 16. The bottom of the slide rod 16 is slidably connected inside the sliding frame 15. During operation, when the telescopic end of the electric push rod 12 drives the support frame 13 and the guide roller 14 to move, the telescopic end of the electric push rod 12 will simultaneously drive the slide rod 16 to move inside the sliding frame 15, thereby facilitating the movement of the guide roller 14 to the strip side and facilitating its guidance of the strip.

[0043] The bottom of the slide rod 16 is adapted to the shape of the sliding frame 15, and a ball bearing is rotatably connected at the contact position between the bottom of the slide rod 16 and the sliding frame 15. During operation, when the strip steel clamps and turns the guide roller 14, the strip steel will simultaneously exert a certain pressure on the guide roller 14. Under the interaction of the slide rod 16 and the sliding frame 15, it can be ensured that the guide roller 14 always guides and limits the strip steel, that is, it avoids the problem of the guide roller 14 deviating from the strip steel.

[0044] Two limiting round rods 5 are provided and are symmetrically arranged relative to the limiting E-type frame 4. The limiting E-type frame 4 is connected to the base plate of the bearing seat 2 by welding and bolts. This design allows the limiting E-type frame 4 to play a supporting role and limit the bearing seat 2.

[0045] During operation, the guide roller body 3 is installed at the outlet and inlet of the six-roll single stand 1, that is, between the inlet / outlet coiler and the stand, and is installed behind the strip roll of the six-roll single stand 1. This installation method is existing technology and will not be described in detail in this embodiment. Then, the strip is fed along the upper and lower guide roller bodies 3, transporting the strip to the pressure rolls of the six-roll mill. The pressure rolls at different positions cold-roll the strip to make the strip surface smooth, flat, and to form the required dimensions. This cold-rolling method is existing technology and will not be described in detail in this embodiment. When the strip is fed and turned along the guide roller body 3, the guide roller body 3 and... When the bearing housing 2 connected to it is subjected to the turning force of the strip and the lateral component force in another horizontal direction, a limiting E-type frame 4 and a limiting mechanism are set on one side of the turning roll body 3 and the bearing housing 2. The limiting E-type frame 4 and the limiting mechanism play a limiting and fixing role, which can prevent the turning roll body 3 from continuing to move after being subjected to lateral force. Through this design, the position of the turning roll body 3 can be guaranteed not to change for a long time, which can reduce the cost of mill accuracy inspection, and also avoid the problem that the horizontal deviation of the turning roll body 3 after lateral movement will cause inconsistent wrap angle, resulting in plate roll measurement error, strip shape difference, strip breakage and other adverse effects.

[0046] It should be noted that before installation, the six-roll mill must first undergo precision testing to ensure that the positions of all rolls are within the standard range when the plate roll position is tested, with the plate roll position as the reference. At the same time, it must be ensured that the horizontal and vertical alignment of the guide roll, plate roll, tension roll, pressure roll, and all rolls in the mill is guaranteed.

[0047] In the initial state, the circular head 501 is located within the arc groove 7. During operation, after the guide roller body 3 and the bearing seat 2 connected to it are subjected to the turning force of the strip and another horizontal component force, part of the horizontal component force is blocked by the limiting E-frame 4. Moreover, under the limiting compression of the limiting round rod 5, the limiting E-frame 4 is ensured to be in the initial position, improving the limiting E-frame 4's limiting of the bearing seat 2, facilitating the turning and clamping of the strip. If the lateral force on the strip is too large during turning, that is, the bearing seat 2 and the limiting E-frame 4 deviate from their initial positions, the limiting E-frame 4 will compress the limiting round rod 5 on the other side, and the circular head on the outer wall of the limiting round rod 5 will be compressed. 501 will disengage from the arc groove 7 and squeeze the elastic frame 8. After one strip feeding is completed, the guide roller body 3 and bearing seat 2 are no longer under force, that is, the elastic frame 8 is no longer under the squeezing force. When the elastic frame 8 returns to its initial state, the elastic frame 8 will drive the limiting round rod 5 to return to its initial position. That is, the round head 501 on the outer wall of the limiting round rod 5 will be stuck in the arc groove 7 again. Since all the rolls have been precision tested in the initial state, and all the roll positions are within the standard of the plate roll position, when the round head 501 is stuck in the arc groove 7 again, the bearing seat 2 and the guide roller body 3 will return to their initial positions, ensuring the forming quality of the strip.

[0048] When the limiting rod 5 moves under excessive force, it will drive the column rod 10 to move within the limiting column groove 9. Under the mutual limiting of the column rod 10 and the limiting column groove 9, the subsequent circular head 501 can be easily locked into the arc groove 7 again, thus facilitating the turning and clamping of the strip by the main body 3 of the turning roller. During the clamping and turning process of the strip, by controlling the electric push rod 12 at different positions, the telescopic end of the electric push rod 12 drives the support frame 13 and the guide roller 14 to move closer to the side wall of the strip, so that the guide roller 14 at different positions contacts the outer wall of the strip. That is, during the turning process, under the limiting of the guide roller 14, the squeezing force of the strip on the main body 3 of the turning roller can be reduced, which is beneficial to the clamping and turning of the strip.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
