Description

Quick-change conveying roller way for steel rolling

Technical Field

The utility model relates to a roll gang is used in quick change formula steel rolling.

Background

In the prior art, the solid flat roll for steel rolling conveying mainly has the problems of inconvenient and quick maintenance and replacement; and simultaneously has the problem of high use cost.

Disclosure of Invention

An object of the utility model is to provide a quick-change formula rollgang for steel rolling can conveniently change the roll table plain-barreled roll fast, is favorable to reducing use cost.

Realize the utility model aims at a quick-change rollgang for steel rolling, including the plain-barreled roll that has the roller, the even interval is fixed and is being set up a plurality of star type support frame on the roller of plain-barreled roll, equally divide in the support frame outside portion and is respectively setting up along the U-shaped recess of plain-barreled roll radial arrangement, the roll surface of plain-barreled roll comprises two half-cylinder roll surface shells, corresponds respectively on the radial internal perisporium of roll surface shell and is setting up a plurality of draw-in groove, support frame outside end card go into the draw-in groove in, set up respectively at the axial both ends of roll surface shell and control fixed lid, follow its both ends of fixing bolt that pass in the U-shaped recess pass about respectively fixed lid and fix through the nut and be in the.

The utility model has two semi-cylindrical roll surface shells which are firmly arranged on the supporting frame above the roll shaft through the action of the fixing cover, the nut and the fixing bolt; the upper surface of the roll shaft is rotationally connected with the fixed shell, the nut and the bolt through keys. After the roller surface shell replacement device is applied, the replacement of the roller surface shell of the online roller way can be completed in a short time; the solid roller body is not required to be made of more materials during manufacturing and use, so that the efficiency of replacement and maintenance operation can be improved; but also can reduce the use cost of the roller way.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.
