Abstract

A roll for rolling metal corrugated plates belongs to the technical field of rolls, and is used for rolling metal corrugated plates for metal composite strips, including roll sleeves, core rolls, and positioning ring sleeves. Outside, the outer surface of the roller sleeve is processed with tooth-shaped protrusions, which can quickly roll out single-sided corrugated metal plates, and use the meshing tooth-shaped protrusions of the double rolls to quickly roll out double-sided corrugated metal plates. During the process, the bonding strength and composite rate of the base plate and the double plate junction are greatly improved; one end of the core roll has a stepped shoulder, and the roll sleeve and the positioning ring sleeve and the core roll are fitted with a small interference amount, and the positioning ring sleeve and The shaft shoulder of the core roller locks and positions the roller sleeve axially and radially, which not only prevents the axial sliding of the roller sleeve and the core roller, but also can quickly replace the roller sleeve with different tooth-shaped convex cross-sectional shapes, and the structure is stable. The service life is long, the utilization rate of the core roll is improved, and the cost of replacing the roll is reduced.

Background technology

At present, the composite metal plate being made up of unlike material has been widely used in every profession and trade, metallic composite technology can be brought into play group element material advantage separately, existing rolling composite billet slab Preparation equipment, employing be flat roll mill rolled slab, substrate and compound plate are with plane closed assembly base, Rolling Production goes out complex plate strip, and after this slab base, the complex plate strip shutting out easily ftractures, recombination rate is low, can not meet existing national product needs; For this reason, design a kind of new blank preparation equipment, for developing a kind of new blank preparation method, strengthen intermetallic adhesion, the composite quality, the combined efficiency that improve dissimilar metal strip become current problem demanding prompt solution.

Summary of the invention

The object of the invention is to provide a kind of roll of rolled metal corrugated plating, for rolled metal complex plate strip base metal corrugated plate used.

For achieving the above object, the invention provides a kind of roll of rolled metal corrugated plating, comprise roller shell, core roller, location ring set, its architectural feature is the outside that roller shell is assemblied in core roller, roller shell outer surface is processed with detent projection, one end of core roller has the step shaft shoulder, and roller shell and location ring set and core roller are by slight interference amount interference fit.

Wherein, described detent projection be parallel to roll mandrel to and continuous distributed on roller shell surface; Or described detent projection perpendicular to roll mandrel to and continuous distributed on roller shell surface; Described detent projection section configuration is respectively ellipse, circular arc, sinusoidal, triangle, rectangle or trapezoidal, and described detent projection height is 1% ~ 90% of rolled composite plate compound plate thickness.

Wherein, described location ring set is fixed on core roller roller shell axial locking is located by set screw, roller shell one end inner surface is processed little draw-in groove and is coordinated radially locking positioning of roller shell with location ring set, the shaft shoulder of the roller shell other end and core roller by alignment pin be connected by roller shell axially, locking positioning radially; After described location ring set and core roll shaft shoulder coordinates with roller shell radially highly lower than roller shell bottom land height; Described roller shell material is high strength cemented carbide steel, and described core roller material is general steel alloy.

Advantage of the present invention and good effect

1 utilizes the present invention to have the roll of detent projection roll surface can roll out rapidly metal substrate and the compound plate of single-face corrugated, utilize the engagement detent projection of two rollers to roll out rapidly Double side ripple metallic plate, in strip recombination process, bond strength between substrate and compound plate faying face improves, and has greatly improved the recombination rate of composite plate;

2 utilize the composite (back-up) roll of roller shell and core roller, the slight interference amount of roller shell and core roller coordinates and mechanical type is located ring set and core roll shaft is takeed on the common use coordinating, both prevented sliding axially of roller shell and core roller, can change fast again the roller shell that detent projection is different section shape, structural stability is good, long service life, has improved the utilization rate of core roller, has reduced the cost of changing roll.
