Description

Technical Field

[0001] The utility model relates to the field of rolling mill maintenance technology equipment, in particular to a high-speed production rolling mill roll ring replacement and cleaning device. Background Art

[0002] The existing high-speed production mill roll ring will be worn on the surface after long-term use in a high-intensity and high-temperature working environment. If the wear is severe, deformation and cracks will occur. Therefore, if the staff finds that the mill roll ring is worn during maintenance, it will be replaced. The main work flow of replacing the roll ring is as follows: first, prepare a new cone sleeve and roll ring. The worker uses sandpaper and industrial wiping cloth combined with industrial alcohol to wipe the outer wall of the cone sleeve to remove foreign matter on the outer wall of the cone sleeve, and then installs the cone sleeve into the roll ring for standby. Secondly, use tools to remove the worn roll ring and cone sleeve from the roll shaft and clean the roll shaft. The worker uses sandpaper and / or industrial wiping cloth combined with industrial alcohol to clean foreign matter on the surface of the cone sleeve and the roll shaft. Finally, use tools to install the roll ring with the cone sleeve on the roll shaft. However, the existing cleaning of the cone sleeve and the outer wall of the roll shaft requires workers to wipe manually, which increases the labor intensity of workers, and the time for workers to manually wipe away foreign matter is long, which increases the time for replacing the roll ring.

[0024] The driving mechanism 2 includes a driving motor 201 and a threaded shaft 202. The threaded shaft 202 is fixedly connected to the end of the output shaft of the driving motor 201 so that when the driving motor 201 is started, its rotating output shaft can drive the threaded shaft 202 to rotate synchronously. A housing 1 for protecting the driving motor 201 is provided on the outer periphery of the driving motor 201. The shape of the housing 1 is cylindrical, and the whole device can stand upright on the ground stably through the lower flat end face of the cylindrical housing 1 when not in use.

Among them, one end of the short side of an L-shaped side plate 104 is welded and fixedly connected to the middle side of a U-shaped plate 103 to form a frame body.

[0026] The two frames are respectively mounted on the left and right sides of the output shaft of the drive motor 201. The U-shaped plates 103 in the two frames are arranged across the drive motor 201. The ends of the U-shaped plates 103 and the L-shaped side plates 104 are welded and fixed to the lower flat end surface of the outer shell 1.

The four connecting rods 305 are evenly spaced along the circumference of the sliding sleeve 302. One end of the connecting rod 305 is hingedly connected to the sliding sleeve 302, and the other end of the connecting rod 305 is hingedly connected to a cleaning rod 307. A torsion spring 306 is provided at the hinge point between the cleaning rod 307 and the connecting rod 305. One end of the torsion spring 306 abuts against the inner side wall of the cleaning rod 307, and the other end abuts against the inner side wall of the corresponding connecting rod 305. Abutment holes distributed along the corresponding length direction are provided on the inner side walls of the corresponding cleaning rod 307 and the connecting rod 305. One end of the torsion spring 306 passes through the abutment hole on the cleaning rod 307 and then abuts against the cleaning rod 307, and the other end of the torsion spring 306 passes through the abutment hole on the connecting rod 305 and then abuts against the connecting rod 305. The setting of the torsion spring 306 can make the cleaning rods 307 tilt toward the direction of the threaded shaft 202, and the four inclined cleaning rods 307 can form an adjustable caliber, and can fit on the outer wall of the cleaning workpiece when the cleaning rods 307 are hooped around the outer wall of the corresponding cleaning workpiece.

[0029] A fixing sleeve 303 is installed at the end of the threaded shaft 202. Four hinge notches 3031 are opened on the side wall of the fixing sleeve 303 near its lower side along its circumference. A support rod 304 is hingedly connected in each hinge notch 3031. One end of the support rod 304 is hingedly connected to the fixing sleeve 303, and the other end of the support rod 304 is hingedly connected to the corresponding connecting rod 305. The support rod 304 can pull the supporting connecting rod 305 to always be in a state as shown in FIG. Figure 1-4 The state distributed around the threaded axis 202 is shown.

[0030] The inner wall of the cleaning rod 307 is adhered with cleaning sandpaper by Velcro, and the frosted surfaces of the cleaning sandpaper are arranged opposite to each other in the direction of the threaded shaft 202, and the frosted surfaces of the cleaning sandpaper are dipped in industrial alcohol. The Velcro includes a Velcro sub-surface 308 and a Velcro mother surface, the Velcro sub-surface 308 is fixed on the inner wall of the cleaning rod 307, and the Velcro mother surface is adhered to the smooth surface of the cleaning sandpaper.

[0031] The specific implementation of the utility model is as follows: when it is necessary to clean the outer wall of the workpiece cone sleeve, the threaded sleeve 301 is manually held and rotated clockwise, the threaded sleeve 301 moves toward the direction close to the fixed sleeve 303, and pushes the sliding sleeve 302 to move accordingly, the connecting rod 305 moves toward the direction close to the fixed sleeve 303, and the cleaning rod 307 moves toward the direction away from the threaded shaft 202 accordingly, then the multiple cleaning rods 307 enclose the opening to expand and open to the diameter of the opening. Figure 2 In the state shown, the plurality of cleaning rods 307 can be quickly hooped and fitted onto the outer side wall of the corresponding cleaning workpiece. Figure 4 In the state shown, the driving motor 201 is started, and the plurality of cleaning rods 307 are driven by the driving motor 201 to rotate to achieve rapid cleaning of the outer wall of the cone sleeve.

[0032] In contrast, when the outer wall of the workpiece roll shaft needs to be cleaned, the worker rotates the threaded sleeve 301 counterclockwise, and the threaded sleeve 301 moves in a direction away from the fixed sleeve 303, and moves with the sliding sleeve 302, the connecting rod 305 moves in a direction away from the fixed sleeve 303, and the cleaning rod 307 moves in a direction close to the threaded shaft 202, so that the multiple cleaning rods 307 enclose the opening and gradually narrow it to Figure 3 In the state shown, multiple cleaning rods 307 are quickly hooped and attached to the outer side wall of the corresponding roller shaft, and the drive motor 201 is started. The multiple cleaning rods 307 are driven by the drive motor 201 to rotate to achieve rapid cleaning of the outer side wall of the corresponding roller shaft.
