Double-station universal type hydraulic automatic roller detaching equipment

Abstract

The invention provides double-station universal type hydraulic automatic roller detaching equipment which comprises a roller translation device, bearing seat supporting devices, two roller lifting devices, bearing seat push-pull devices and buffering devices, wherein the roller translation device comprises a roller translation hydraulic cylinder and a translation trolley arranged at the front end of the roller translation hydraulic cylinder; the translation trolley is slidably mounted on a trolley bracket; the roller translation hydraulic cylinder is mounted on a rack; the bearing seat supporting devices are used for fixing and supporting bearing seat assemblies to be detached and comprise foundation supports and clamping adjustment mechanisms arranged on the foundation supports, and the foundation supports are mounted on the translation trolley; the two roller lifting devices are arranged side by side, the roller lifting devices comprise lifting hydraulic cylinders and roller supporting seats mounted at the front end of the lifting hydraulic cylinders, the top ends of the roller supporting seats are provided with V-shaped grooves, and the lifting hydraulic cylinders are mounted on the translation trolley; the bearing seat push-pull devices are used for pushing the trolley bracket to move and comprise push-pull hydraulic cylinders mounted on the rack; the buffering devices are arranged corresponding to the translation trolley. By means of the double-station universal type hydraulic automatic roller detaching equipment, efficient, reliable and safe detaching and mounting of roller bearing seats can be achieved.

Description

technical field [0001] The invention belongs to the field of dismantling and installing equipment for hot-rolled flat-roll rolling mills, and in particular relates to a double-station general-purpose hydraulic automatic roll dismantling equipment. Background technique [0002] Roll wear is unavoidable in the hot-rolled narrow-strip rolling process. Roll wear will lead to changes in roll surface quality, geometric dimensions and roll shape, etc. These changes will seriously affect the product quality of hot-rolled narrow strip steel. In order to ensure product quality, the roll must be replaced in time. In addition, the operating condition of the main bearing in the roll bearing housing is also an important factor affecting the quality of rolled products and the production efficiency of the steel plant, and must be ready for replacement at any time. This requires that the chocks must be disassembled from both ends of the roll regularly and quickly so as to regrind the rolls...

AI Technical Summary

Problems solved by technology

However, one type of rolling mill must correspond to one type of roll removal device. In this way, not only the initial investment is large, but also the equipment occupies a large area

In addition, for the narrow-strip rough rolling mill, the roll change frequency is relatively small, mainly because the work roll change frequency of the finishing mill is high.

In this way, it is not worthwhile to configure a special roll removal device for the roughing mill, but its bearing housing and roll weight are the largest in the whole unit, the assembly difficulty is also the greatest, and the roll removal device is most urgently needed. This is an unavoidable problem for most steel mills to consider whether to install the roll removal device.
