Vertical roller mill

Abstract

The invention provides a vertical roller mill, belonging to the technical field of machinery and solving the problems of the existing vertical roller mill that a pulling roller cylinder cannot be replaced and maintained conveniently. The vertical roller mill comprises a speed reducer platform, a speed reducer platform bracket used for supporting the speed reducer platform, a speed reducer fixed on the speed reducer platform, a main motor connected with the input end of the speed reducer, a milling roller system connected with the output end of the speed reducer through a universal coupling, a milling roller adjusting device used for adjusting the opening of the roller system, a rack used for supporting the milling roller system and the milling roller adjusting device and a rack track seat used for supporting the rack. The milling roller adjusting device comprises a first adjusting device used for reducing the opening of the roller system and a second adjusting device used for increasing the opening of the roller system, and the second adjusting device is arranged outside the rack. Since the second adjusting device used for increasing the opening of the roller system is arranged outside the rack, the installation, removal and maintenance of the pulling roller cylinder are greatly facilitated.

Description

technical field [0001] The invention belongs to the field of mechanical processing and relates to a vertical rolling mill. Background technique [0002] A rolling mill is the equipment that realizes the metal rolling process. A traditional rolling mill mainly includes a reducer platform, a reducer platform support for supporting the reducer platform, a reducer fixed on the reducer platform, a main motor connected to the input end of the reducer, and a universal coupling connected to the reducer. The roll system connected to the output end, the roll adjustment device for adjusting the opening of the roll system, and the frame used to support the roll system and the roll adjustment device, the roll opening can be adjusted through the roll adjustment device to meet different needs , In the prior art, the reduction of the opening of the roll system is operated by the screw rod, and the increase of the opening is driven by the piston rod of the oil cylinder. [0003] In the pri...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the oil cylinder is arranged in the frame, and there is only one oil cylinder on each side. Therefore, when there is a problem with the oil cylinder, it is troublesome to replace and repair. After the rack is disassembled, dust and other sundries will enter the rack, which will affect the work of the machine to a certain extent.
