Description

Automatic roller ring dismounting tool and method for rolling mill roller ring

Technical Field

The invention relates to an automatic roll dismounting tool and a roll dismounting method for a roll collar of a rolling mill.

Background

The collar assembly is mounted on the mill spindle for extruding the wire/rod to the desired profile dimensions. The precision of the roll collar is related to the product quality, so the roll collar needs to be replaced in time due to the abrasion of the roll collar after rolling for a certain time (the replacement frequency of the roll collar is related to the excessive steel quantity). The roller ring assembly is mainly divided into a protective cap, a taper sleeve and a roller ring body. The taper sleeve is positioned between the main shaft of the rolling mill and the roller collar, the roller collar is tensioned and fixed by matching with the conical surface of the main shaft of the rolling mill, and the outer end of the taper sleeve is provided with a nut which is in threaded connection with the main shaft. The protective cap is installed outside the taper sleeve and is fixedly connected with the inner thread of the main shaft through a screw rod.

At present, the roller ring is disassembled manually by a special roller disassembling tool. The roller removing tool uses hydraulic pressure to pull out the taper sleeve through pressure. After the roller ring protective cap is detached, manually placing a roller detaching tool on the roller ring and the taper sleeve and fixing the roller detaching tool, and starting the roller detaching tool to pressurize to pull out the taper sleeve. The roll collar needs frequent replacement and maintenance, and the prior manual disassembly of the roll collar has the conditions of repeated labor, high labor intensity, long replacement time, low efficiency, high temperature of working environment, easy occurrence of danger and the like.

Description of the drawings:

FIG. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

in order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

The invention provides an automatic roll dismounting tool for a roll collar of a rolling mill, which is simple and reliable in structure, can be combined with a mechanical arm to realize roll dismounting process automation by utilizing the existing roll dismounting tool to add a cylinder body and clamping mechanisms. Mainly comprises a cylinder body 1, a clamping mechanism 2, a supporting rod component 3, a hydraulic roller dismounting tool 4 and a sliding rail sliding block 5.

The hydraulic roller dismounting tool is mainly characterized in that the hydraulic roller dismounting tool 4 and the cylinder body 1 are fixed by screws; the clamping mechanism is fixed at the lower end of the cylinder body 1 and used for clamping the roller ring, and consists of a hydraulic cylinder, a clamping plate and a sliding rail sliding block; the supporting rod component 3 is connected with the cylinder 1 through a sliding rail and a sliding block; the supporting rod assembly 3 can be connected with a mechanical arm; the upper end of the cylinder body 1 is hollow, and a hydraulic pipeline installation space is reserved.

The clamping mechanism 2 comprises a supporting table 2-4, the supporting table 2-4 and the barrel 1 are of an integral structure, a hydraulic cylinder 2-1 is mounted on the upper portion of the supporting table 2-4, a hydraulic rod of the hydraulic cylinder 2-1 is connected with one end of a fixing block 2-5, a clamping plate 2-3 is arranged at the other end of the fixing block 2-5, the clamping plate 2-3 is mounted at the bottom of the supporting table 2-4 through a sliding block 2-2, and the clamping plate 2-3 is used for clamping and fixing a roller ring.

When the clamping mechanism needs to lock the taper sleeve 6, the clamping plate moves according to the sliding block, the hydraulic rod moves, and the roll collar 6 is loosened and clamped.

The working principle is as follows:

roller instrument 4 and barrel 1 fixed connection are torn open to hydraulic pressure, and the arm will tear the roller instrument open automatically and arrange the roller ring awl in and sheathe in, and the arm will tear the roller instrument open automatically and rotate certain angle, makes roller instrument 4 and the card limit card of taper sleeve card together torn open to hydraulic pressure. The center of the hydraulic roller detaching tool props against a main shaft of the rolling mill, and a hydraulic system pressurizes to pull out the taper sleeve.
