Description

Technical Field

[0001] This utility model relates to the field of guide roller technology, specifically to a four-position adjustable rolling guide roller device. Background Technology

[0002] Rolling is a finishing process in the steel industry, a process for mass production of steel materials; the rolling mill guide rolls are an important mechanism for realizing the metal rolling process, which can improve rolling efficiency and product quality, and are widely used in manufacturers of metal sheets and strips.

[0003] Chinese Patent 202220839656.2 discloses a dual-position rolling guide roller, but this rolling guide roller can only guide and adjust the rolling roller up and down. During the rolling process, if the product thickness changes (after multiple rolling, its thickness will become thinner and thinner), its width will also change accordingly. However, this dual-position rolling guide roller cannot adjust the left and right positions, and therefore cannot adjust the changes in width. Utility Model Content

[0004] Based on this, the purpose of this utility model embodiment is to provide a four-position adjustable rolling guide roller device, which can adjust the rolling guide roller in four directions (up, down, left, and right) to quickly adapt to the shape changes of steel during the rolling process, thereby improving rolling efficiency and product quality.

[0005] A four-position adjustable rolling guide roller device includes a fixed frame, several rolling guide rollers, several rotating shafts, several guide rods, several connecting parts, and several driving mechanisms.

[0006] The plurality of rolling guide rolls are located within the fixed frame, including an upper rolling guide roll, a lower rolling guide roll, a left rolling guide roll, and a right rolling guide roll. The upper rolling guide roll is arranged parallel to the lower rolling guide roll, the left rolling guide roll is arranged parallel to the right rolling guide roll, and the upper rolling guide roll is perpendicular to the left rolling guide roll.

[0007] The plurality of rotating shafts include an upper rolling guide roll rotating shaft, a lower rolling guide roll rotating shaft, a left rolling guide roll rotating shaft, and a right rolling guide roll rotating shaft. The upper rolling guide roll rotates around the upper rolling guide roll rotating shaft, the lower rolling guide roll rotates around the lower rolling guide roll rotating shaft, the left rolling guide roll rotates around the left rolling guide roll rotating shaft, and the right rolling guide roll rotates around the right rolling guide roll rotating shaft. The length of the rolling guide roll is shorter than the rotating shaft. Both ends of the lower rolling guide roll rotating shaft are connected to the fixed frame.

[0008] The plurality of connecting parts include an upper connecting part, a left connecting part, and a right connecting part. The upper rolling guide roller rotating shaft is connected to the upper connecting part through the guide rod. The left rolling guide roller rotating shaft is connected to the left connecting part through the guide rod. The right rolling guide roller rotating shaft is connected to the right connecting part through the guide rod.

[0009] The plurality of driving mechanisms include an upper driving mechanism, a left driving mechanism, and a right driving mechanism. The upper driving mechanism is used to drive the upper connecting part to move up and down, the left driving mechanism is used to drive the left connecting part to move left and right, and the right driving mechanism is used to drive the right connecting part to move left and right.

[0010] This invention designs a four-position (up, down, left, and right) adjustable rolling guide roller device. Operators can quickly adjust the various drive mechanisms to adjust the position of each rolling guide roller, which facilitates rapid adaptation to changes in the width and thickness of steel during rolling. In addition, the four-position rolling guide rollers can also limit the size of the steel, preventing irregular deformation and improving rolling accuracy.

[0011] As a preferred embodiment, the connecting part is located outside the fixed frame, the guide rod passes through the fixed frame, and both ends of the guide rod are perpendicularly connected to the connecting part and the rotating shaft of the rolling guide roller. The perpendicular arrangement of the guide rod to the connecting part and the rotating shaft facilitates the connection of the guide rod and also facilitates the movement of the connecting part and the rotating shaft.

[0012] As a preferred embodiment, the rotating shaft is located within the fixed frame. This results in a compact overall structure and greater stability when adjusting the rolling guide rollers.

[0013] As a preferred embodiment, the drive mechanism includes a screw, and the connecting portion has a threaded hole. The screw passes through the connecting portion and is threadedly connected to it, abutting against the fixed frame. Through the threaded connection, the position of the connecting portion can be precisely adjusted when the screw rotates, thereby precisely adjusting the position of the rolling guide roller.

[0014] As a preferred embodiment, the screw is perpendicular to the connecting portion and located at the center of the connecting portion. This makes the screw require less effort to rotate and ensures that the connecting portion is subjected to balanced forces.

[0015] As a preferred embodiment, the drive mechanism further includes a rotary driver for driving the screw to rotate. Adjustment via the rotary driver requires less effort and facilitates automatic adjustment of the spacing between the rolling guide rolls.

[0016] As a preferred embodiment, the system further includes a guide sleeve, which is a hollow structure that passes through and is fixed to the mounting frame, with the guide rod passing through the guide sleeve. More preferably, the guide sleeve is made of a linear bearing. The guide sleeve guides the guide rod to move in a straight line and avoids the influence of the guide rod's movement on the mounting frame.

[0017] As a preferred embodiment, a return spring is also included, which is fitted onto the outside of the guide rod, with its two ends abutting against the rotating shaft and the guide sleeve. Since the steel is rolled continuously, its width may change. To prevent jamming, return springs are added to the left and right guide rods. When the steel is too wide, it will spread apart the left and right rolling guide rollers, compressing the return springs and increasing the distance between them, allowing the steel to pass through. When the steel is too narrow, the return springs will return to their original position, ensuring that the left and right rolling guide rollers can closely adhere to the steel, further improving rolling accuracy. Similarly, when the thickness changes, the return spring at the upper guide rod will also compress and return to its original position.

[0018] As a preferred embodiment, the system also includes adjusting brackets, with both ends of the lower rolling guide roller's rotating shaft being detachably and height-adjustably connected to the fixed frame via the adjusting brackets. The height of the lower rolling guide roller from the ground can be adjusted using the adjusting brackets at both ends, ensuring that the rolling surface is at the same height as the lower rolling guide roller, thus facilitating rolling.

[0019] As a preferred embodiment, the fixed frame has several first fixing holes distributed along the height direction on its left and right sides, and the adjusting bracket has second fixing holes on both sides. The adjusting bracket is detachably connected to the fixed frame through the first and second fixing holes. The height of the adjusting bracket relative to the ground is adjusted through the first and second fixing holes, thereby adjusting the height of the lower rolling guide roller, so that the height of the lower rolling guide roller is aligned with the height of the rolling surface.

[0020] The four-position adjustable rolling guide roller device provided by this utility model is designed with an adjustable rolling surface. During rolling, the height of the rolling surface from the ground is first measured, and then the height of the lower rolling guide roller is adjusted through two sets of adjustment brackets to make the height of the lower rolling guide roller the same as the height of the rolling surface, so as to adapt to different rolling heights. In addition, through the design of the screw and screw hole, the operator only needs to rotate the screw to quickly and accurately adjust the distance between the rolling rollers, which can quickly adapt to the changes in the width and thickness of steel during rolling. Furthermore, the design of the guide sleeve reduces the impact of the guide rod on the overall frame during movement, maintaining the overall stability of the frame. In addition, the setting of the return spring not only prevents jamming or rolling failure due to untimely adjustment by the operator, but also further improves the rolling accuracy.

Therefore, they should not be construed as limitations on this utility model.

[0026] like Figures 1-2 As shown, a four-position adjustable rolling guide roller device includes a fixed frame, a rolling guide roller, a rotating shaft, a guide rod, a connecting part, a screw, a linear bearing 7, a return spring 8, an adjusting bracket 9, and a motor (not shown in the figure).

[0027] There are four rolling guide rolls located within the fixed frame 1, including an upper rolling guide roll 21, a lower rolling guide roll 22, a left rolling guide roll 23, and a right rolling guide roll 24. The upper rolling guide roll 21 and the lower rolling guide roll 22 are arranged in parallel, the left rolling guide roll 23 and the right rolling guide roll 24 are arranged in parallel, and the upper rolling guide roll 21 and the left rolling guide roll 23 are perpendicular.

[0028] There are four rotating shafts located within the fixed frame 1, including an upper rolling guide roller rotating shaft 31, a lower rolling guide roller rotating shaft 32, a left rolling guide roller rotating shaft 33, and a right rolling guide roller rotating shaft 34. The upper rolling guide roller 21 passes through the upper rolling guide roller rotating shaft 31 and can rotate around it. The lower rolling guide roller 22 passes through the lower rolling guide roller rotating shaft 32 and can rotate around it. The left rolling guide roller 23 passes through the left rolling guide roller rotating shaft 33 and can rotate around it. The right rolling guide roller 24 passes through the right rolling guide roller rotating shaft 34 and can rotate around it.

[0029] There are 6 linear bearings 7, with two on the upper, left and right sides of the fixed frame 1, and they pass through and are fixed to the fixed frame 1; there are 6 guide rods 4, each of which passes through one of the linear bearings 7, and each guide rod 4 is also fitted with a return spring 8. The two ends of the upper rolling guide roller rotating shaft 31, the left rolling guide roller rotating shaft 33 and the right rolling guide roller rotating shaft 34 are respectively connected to one of the guide rods 4; the two ends of the return spring 8 abut against the rotating shaft 3 and the linear bearing 7 respectively.

[0030] There are three connecting parts, which are plate-shaped and located outside the fixed frame 1. They include an upper connecting part 51, a left connecting part 53, and a right connecting part 54. Each connecting part has a screw hole at its center. The two ends of each guide rod 4 are connected to the rotating shaft and the connecting part, respectively. The upper connecting part 51 is arranged parallel to the upper rolling guide roller 21, the left connecting part 53 is arranged parallel to the left rolling guide roller 23, and the right connecting part 54 is arranged parallel to the right rolling guide roller 24.

[0031] There are three screws: an upper screw 61, a left screw 63, and a right screw 64. The upper screw 61 passes vertically through the center of the upper connecting part 51, is threaded into the upper connecting part 51, and abuts against the fixing frame 1, driving the upper connecting part 51 to move up and down. The left screw 63 passes vertically through the center of the left connecting part 53, is threaded into the left connecting part 53, and abuts against the fixing frame 1, driving the left connecting part 53 to move left and right. The right screw 64 passes vertically through the center of the right connecting part 54, is threaded into the right connecting part 54, drives the right connecting part 54 to move left and right, and abuts against the fixing frame 1. A motor is used to drive the screws to rotate, reducing the labor intensity of workers and facilitating automatic adjustment.

[0032] The left and right sides of the fixed frame 1 each have two rows of vertically arranged first fixing holes 11. There are two sets of adjusting brackets 9 located outside the fixed frame 1. The adjusting brackets 9 have waist-shaped holes 91 on both sides. The two ends of the lower rolling guide roller 22 are respectively fixed to one set of adjusting brackets 9. The adjusting brackets 9 and the fixed frame 1 are detachably connected to the first fixing holes 11 through the waist-shaped holes 91.

[0033] The working principle of this utility model is as follows: The height of the rolling surface from the ground is measured, and then the height of the lower rolling guide roller 22 is adjusted using two sets of adjusting brackets 9 so that the height of the lower rolling guide roller 22 is the same as the height of the rolling surface. Then, bolts are used to pass through the oblong hole 91 and the first fixing hole 11 to fix the adjusting bracket 9 to the fixing frame 1. Based on the thickness and width of the steel, the upper screw 61 is rotated, causing the upper connecting part 51 to move up and down relative to the fixing frame 1, driving the guide rod 4, the upper rolling guide roller rotating shaft 31, and the upper rolling guide roller 21 to move up and down, adjusting the distance between the upper rolling guide roller 21 and the lower rolling guide roller 22 to be slightly lower than the steel thickness; similarly, the left rolling guide roller 23 and the right rolling guide roller 24 are adjusted by rotating the left screw 63 and the right screw 64 respectively, so that their distance is slightly lower than the steel width.

[0034] During rolling, the rolling guide rolls rotate around the rotation axis, and the steel rolls relative to the rolling guide rolls, reducing friction on the steel surface and preventing irregular deformation caused by localized heat accumulation. The thickness and width of the steel will change. The distance between the upper rolling guide roll 21 and the lower rolling guide roll 22, and the distance between the left rolling guide roll 23 and the right rolling guide roll 24, are adjusted by rotating the screw driven by a motor, achieving continuous rolling. In addition, the guide rod 4 is equipped with a return spring 8. During rolling, the return spring 8 stores a certain amount of elastic potential energy, which can prevent jamming or rolling failure due to untimely screw adjustment. When the width of the steel is too wide, the steel will... The left rolling guide roller 23 and the right rolling guide roller 24 are spread apart, the return spring 8 is compressed, and the guide rod 4 is pushed open to both sides, increasing the distance between the left rolling guide roller 23 and the right rolling guide roller 24, allowing the steel to pass through. When the width of the steel is too narrow, the return spring 8 will return to its original position, pushing the left rolling guide roller rotation shaft 33 and the right rolling guide roller rotation shaft 34 closer together, reducing the distance between the left rolling guide roller 23 and the right rolling guide roller 24, ensuring that the left rolling guide roller 23 and the right rolling guide roller 24 can fit tightly against the steel, and further improving the rolling accuracy. Similarly, when the thickness changes, the return spring 8 at the upper guide rod will also be compressed and returned to its original position.

[0035] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
