Description

Technical Field

[0001] This utility model belongs to the technical field of metallurgical rolling auxiliary equipment, and relates to a side guide wheel structure that can be quickly replaced. Background Technology

[0002] In the setup of a 20-roll mill, the strip correction CPC is activated during the uncoiler pass. Since the uncoiler is far from the 20-roll mill, a side guide wheel is installed at the mill entrance to prevent the strip from deviating. During rolling, the opening of the side guide wheel is adjusted according to the strip width so that the working state of the side guide wheel matches the strip width.

[0003] Based on past production and commissioning experience and user feedback, the existing side guide wheel structure exhibits the following issues, leading to side guide component failure, such as copper sleeve jamming, severe wear of the side guide wheel, and strip edge curling: 1) The existing side guide wheel rotating components use self-lubricating copper sleeves. During rolling, the strip rubs against the side guide wheel, and the strip's movement drives the side guide wheel to rotate. Over time, the copper sleeve is prone to jamming, preventing the side guide wheel from rotating with the strip, resulting in abnormal wear of the side guide wheel. In severe cases, this can lead to strip edge curling or strip breakage. 2) Because the ZR22 Sendzimir mill has an integral frame and an oil removal roller at the inlet with a small opening, and the mill inlet is a closed entrance with limited working space, the existing side guide wheel assembly cannot be quickly disassembled and reassembled. Therefore, if the side guide wheel is damaged, manual replacement at the mill inlet is required, which is extremely inconvenient and significantly delays production. Utility Model Content

[0004] This invention solves the problem of the side guide roller assembly being difficult to replace in the prior art. Furthermore, by replacing the side guide wheel that relies on a self-lubricating copper sleeve for rotation with a standard sealed roller bearing, the risk of copper sleeve jamming and abnormal wear of the side guide wheel is reduced. In addition, the standard roller bearing makes it easier to configure roller spare parts.

[0005] The technical solution adopted in this utility model is a quick-changeable side guide wheel structure, including a lead screw and a side guide roller frame. One end of the lead screw is hinged to a coupling one, and the other end of the lead screw is connected to a coupling two. Both ends of the lead screw hinged to coupling one and coupling two are radially fixed with limit plates. A roller frame support is slidably fitted on the inner side of each end of the lead screw body section. Each roller frame support has a groove in the end face facing the limit plate. The bottom of each side guide roller frame has a sharp corner corresponding to the roller frame support, and the sharp corner extends into the groove. A roller bearing is installed in the side guide roller frame, and the outer ring of the roller bearing serves as the side guide wheel.

[0006] The quick-replaceable side guide wheel structure of this utility model is further characterized in that: Roller bearings are installed inside the side guide roller frame via pins.

[0007] The other end of the coupling is connected to a hydraulic motor drive.

[0008] The two outer ends of the coupling are connected to a manual turntable drive.

[0009] Nuts are fixedly installed inside the roller support.

[0010] The threaded sections at the corresponding positions of the nut and the lead screw are connected by threads.

[0011] The roller bearings are sealed roller bearings.

[0012] The side guide roller frame can rotate around the edge of the slot on the roller frame support.

[0013] The beneficial effects of this utility model are as follows: First, it eliminates the original self-lubricating copper sleeve and replaces the original non-standard roller with a standard sealed roller bearing, preventing emulsion and debris from entering the rolling elements, reducing the risk of side guide wheel jamming, and improving the lubrication and wear resistance of the side guide wheel. Second, it modifies the design structure of the side guide wheel frame, using a single-sided dovetail and slot to fix it to the side guide support, enabling quick replacement of the side guide wheel frame and greatly saving the replacement time of the side guide wheel assembly. The improved quick replacement structure reduces the replacement time of the side guide wheel assembly by more than 60%, which is of great significance for improving production efficiency and maintaining the good operating condition of the equipment.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figure 1 , Figure 2 , Figure 3 The structure of the quick-replaceable side guide wheel of this utility model includes a lead screw 2 and a side guide roller frame 3. One end of the lead screw 2 is hinged to a coupling 1, the outer end of which is driven by a hydraulic motor 12. The other end of the lead screw 2 is connected to a coupling 2 13, the outer end of which is driven by a manual handle 11. A roller frame support 6 is slidably fitted on each side of the main body of the lead screw 2. A nut 7 is fixedly installed in each roller frame support 6 (each roller frame support 6 and the nut 7 are fixed as one piece). The nut 7 and the threaded section of the lead screw 2 at the corresponding position are connected by threads. The hydraulic motor 12 drives the lead screw 2 to rotate through the coupling 1. When the lead screw 2 rotates, it forces the nut 7 to drive the roller frame support 6 to move axially.

[0018] Both ends of the lead screw 2 hinged coupling 1 and coupling 2 13 are radially fixed with limiting plates 8. The end face of the roller support 6 facing the limiting plate 8 has an acute-angled groove 10. The bottom of the side guide roller frame 3, corresponding to the groove 10 of the roller support 6, has a dovetail-shaped pointed corner 9 that extends into the groove 10. During normal operation, the pointed corner 9 presses firmly against the groove 10.

[0019] The operation process of this utility model for quickly replacing the side guide wheel structure is as follows: First, see Figure 6 The roller support 6 needs to be moved along with the lead screw 2 to a position that the operator can directly reach by hand from the outside of the machine. Then, see Figure 5 Rotate the side guide roller frame 3 clockwise around the dovetail side, and during the rotation, bring the side guide roller frame 3 close to the groove edge of the slot 10 of the roller frame support 6 while rotating, until the sharp corner 9 of the side guide roller frame 3 comes out of the dovetail groove of the roller frame support 6; then, the side guide roller frame 3 and the pin 4 and roller bearing 5 installed on the side guide roller frame 3 can be quickly removed, and the new roller bearing 5 is replaced, which is equivalent to replacing the side guide roller.

[0020] Finally, when installing the side guide roller frame 3, the operation sequence is reversed.
