Description

Technical Field

[0001] This utility model relates to the field of rolling mill production technology, and in particular to a rolling mill base guide device. Background Technology

[0002] A rolling mill is a piece of equipment that realizes the metal rolling process. It generally refers to the equipment that completes the entire process of rolling material production. Most common rolling mills currently use a transmission line on the base of the rolling mill to transport steel to the rolls for rolling.

[0003] However, during the rolling of metal sheets in a rolling mill, the transport process of the metal sheet by the base conveyor line may cause the sheet to tilt to a certain extent, so that the sheet does not enter the rolling mill at a vertical angle. This results in uneven initial stress on the sheet (one corner of the sheet will be rolled first), which leads to some deformation at the edges and corners of the sheet after rolling, reducing rolling efficiency. Currently, the common way to deal with this situation is to manually align the sheet with a ruler in front of the rolling mill. This method is not only labor-intensive, but also the accuracy of manual alignment is not enough, and the sheet tilting may still occur.

[0004] Therefore, it is necessary to provide a new mill base guide device to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a mill base guide device that is easy to operate, saves manpower, and improves rolling efficiency and quality.

[0006] To solve the above-mentioned technical problems, the present invention provides a mill base guide device comprising: a mill base and a support frame fixedly installed on the mill base, characterized in that sliding plates are slidably installed on the inner walls of both sides of the support frame, guide plates are slidably installed on both sliding plates, and multiple balls are embedded on the outer wall of the side of the two guide plates that are close to each other.

[0007] Preferably, a receiving cylinder is fixedly installed on one side of the outer wall of any sliding plate, a threaded rod is placed inside the receiving cylinder, one end of the threaded rod extends to the outside of the receiving cylinder and is fixedly connected to the guide plate, a rotating sleeve is sleeved on the outer wall of the receiving cylinder, a threaded cylinder is fixedly installed on the rotating sleeve, and one end of the threaded rod passes through the threaded cylinder and is threadedly connected to it.

[0008] Preferably, two transverse sliding plates are slidably installed on the inner walls of both sides of the support frame, and the sliding plates are connected to the two transverse sliding plates through a hinge plate.

[0009] Preferably, lifting plates are slidably installed on both outer walls of the support frame, and the lifting plates are connected to the two transverse sliding plates through hinge plates.

[0010] Preferably, a rotating shaft is rotatably installed on both outer walls of the support frame, and an eccentric wheel is fixedly sleeved on each of the two rotating shafts. The two eccentric wheels are slidably connected to the two lifting plates respectively.

[0011] Preferably, a rotating rod is rotatably mounted on the top of the support frame, and synchronous pulleys are fitted on both ends of the rotating rod and on the two rotating shafts, with transmission belts fitted on the corresponding two synchronous pulleys.

The output shaft of the drive motor extends into the mounting bracket, and the output shaft of the drive motor is connected to the rotating rod through a bevel gear set.

[0013] Compared with related technologies, the mill base guide device provided by this utility model has the following advantages:

[0014] This utility model provides a rolling mill base guide device, which uses two guide plates that move away from each other and then move closer together. When a metal sheet passes through, the guide plates come into contact with the outer walls of both sides of the metal sheet, thereby aligning the metal sheet and preventing it from entering the rolling mill at an angle. This improves the rolling quality, prevents deformation during rolling, and eliminates the need for manual intervention, reducing labor costs and improving the accuracy of the metal sheet alignment.

The two eccentric wheels 10 are slidably connected to the two lifting plates 8 respectively. Figure 7 As shown, a groove 101 is provided on the curved wall of the eccentric wheel 10, and an embedded slider 102 is fixedly installed on the top of the lifting plate 8. The two embedded sliders 102 are slidably connected to the inner walls of the two grooves 101 respectively. In order to prevent the eccentric wheel 11 from separating from the lifting plate 8, the embedded slider 102 and the groove 101 adopt a T-shaped embedded design.

[0030] A rotating rod 12 is rotatably mounted on the top of the support frame 3. Protrusions are fixedly installed on both sides of the top of the support frame 3. The rotating rod 12 passes through the two protrusions and is rotatably connected to them. Synchronous pulleys 13 are sleeved on both ends of the rotating rod 12 and on the two rotating shafts 10. A transmission belt is sleeved on the corresponding two synchronous pulleys 13.

[0031] A mounting bracket 14 is fixedly installed on the top of the support frame 3. The mounting bracket 14 is in the shape of the letter "n". The opening of the mounting bracket 14 is installed downward. A drive motor 15 is fixedly installed on the top of the mounting bracket 14. The output shaft of the drive motor 15 extends into the mounting bracket 14. The output shaft of the drive motor 15 is connected to the rotating rod 12 through a bevel gear set 16. The bevel gear set 16 includes two bevel gears. The two bevel gears are fixedly installed on the outer wall of the rotating rod 12 and the bottom end of the output shaft of the drive motor 15, respectively. The two bevel gears mesh with each other.

[0032] The working principle of the mill base guide device provided by this utility model is as follows:

[0033] When rolling metal sheets through a rolling mill and transporting the sheets into the rolling mill using a rolling mill base 1, the metal sheets are laid flat on the rolling mill base 1 and then transported into the rolling mill through the rolling mill base 1.

[0034] When the metal sheet approaches the range of the support frame 3, the operator can start the drive motor 15. After the output shaft of the drive motor 15 starts rotating, it will drive the rotating rod 12 to rotate under the transmission effect of the bevel gear group 16, which in turn drives the two synchronous pulleys 13 located on the rotating rod 12 to rotate. Under the transmission effect of the two transmission belts, it will further drive the two rotating shafts 10 to rotate, thereby causing the two eccentric wheels 11 to rotate. During the rotation of the two eccentric wheels 11, when the eccentric wheel 11 rotates half a circle away from the center and contacts the lifting plate 8, it will drive the lifting plate 8 to move downward. When the eccentric wheel 11 rotates half a circle closer to the center and contacts the lifting plate 8, it will cause the lifting plate 8 to move upward under the pulling effect of the slide groove 101 on the embedded slider 102. Thus, with the drive motor 15 starting and driving the two eccentric wheels 11 to rotate continuously, the two lifting plates 8 will continuously perform lifting and lowering movements.

[0035] During the lifting and lowering movement of the lifting plate 8, when the lifting plate 8 moves downward, it will cause the top ends of the two hinge plates 9 to move downward, thereby causing the bottom ends of the two hinge plates 9 to move away from each other. This, in turn, causes the two transverse plates 6 to move away from each other. The two transverse plates 6 moving away from each other will then cause one end of the two hinge plates 7 to move away from each other, thereby causing the other end of the two hinge plates 7 to move closer to one side of the inner wall of the support frame 3. Finally, the sliding plate 4 and the guide plate 5 will move closer to one side of the inner wall of the support frame 3 (the guide plates 5 on both sides move away from each other). Conversely, during the upward movement of the lifting plate 8... During the process, the sliding plate 4 will move away from the inner wall of the support frame 3 (the two guide plates 5 will move closer to each other). In summary, during the continuous up-and-down movement of the lifting plate 8, the two guide plates 5 will move back and forth, either moving closer to each other or further away from each other. Thus, when the metal plate passes the support frame 3, the two guide plates 5 will first move away from each other, and when the metal plate is between the two guide plates 5, the two guide plates 5 will move closer to each other again, thereby aligning the metal plate. The setting of multiple ball bearings 21 will also align the metal plate without affecting its normal movement.

[0036] Furthermore, when dealing with plates of different widths, the operator can rotate the rotating sleeve 18. The rotation of the rotating sleeve 18 will drive the threaded cylinder 20 to rotate, thereby moving the threaded rod 171 out, thus adjusting the distance between the guide plate 5 and the sliding plate 4, so as to cope with the alignment of metal plates of different specifications.
