Description
Technical field
Roll technology field is the utility model is related to, particularly relates to a kind of hard alloy roll.
Background technology
Roll wants consumption in operation part as rolling mill main, and all having on product quality, production efficiency etc. directly influences.Hard
Alloy roller is good because having the advantages that single groove steel transportation amount height, negative common difference precise control, product surface quality, it has also become wire rod rolls
Face, especially high-speed rod-rolling mill finish rolling, pre- finish rolling, in the main roll material that rolls.
According to different requirements, roller surface form processing mainly has two kinds：One kind is to utilize wire drawing machine by roll
Surface Machining is into tooth form；Another kind is using the mode of sandblasting (or pressure sand), and roller surface is processed into mat surface.Roll makes
The serious wear during, typically using 2~April after, carried out because technological requirement can not be met repeat processing.Often process one
Secondary, roller diameter reduces 0.5~6mm, after multiple, is just scrapped because that can not meet equipment requirement.Roll contracts because of diameter
Subtract and scrap, not only increase the acquisition cost of roll, more cause the huge waste of material, the energy and resource.
Therefore, it is necessary to a kind of new hard alloy roll is designed, to solve above-mentioned technical problem.
Utility model content
For problem present in background technology, the purpose of this utility model is to provide a kind of hard alloy roll, can be with
The huge waste of roll is avoided, saves production cost and social resources.
What the technical solution of the utility model was realized in：A kind of hard alloy roll, including connect with pressure rolling material
Tactile outer layer and the internal layer being fused in the outer layer, the outer layer is different from the material of internal layer, and the internal layer is outer by being fused to
Layer core and from core one toward both sides extend and exceed outer layer both ends driving side axle portion and slave end axle portion composition, institute
State that driving side axle portion is equal with the diameter of slave end axle portion, the end of the driving side axle portion has been wholely set for passing on driving
The clutch section of moment of torsion, a pair of flat breach that the clutch section has straight first end face and engaged with drive mechanism
Face, the pair of breach face are parallel to each other, and the first end face is vertical with a pair of breach faces, the end one of the slave end axle portion
Body is provided with convex shaped part, and the convex shaped part has straight second end face, and the area of the second end face is more than the face of first end face
Product, the outer surface of the outer layer are provided with clad, and the clad is embedded with high hardness alloy powder, and the outer surface of clad
With equally distributed laser alloying point.
In the above-mentioned technical solutions, the laser alloying point is circle.
In the above-mentioned technical solutions, the laser alloying point is ellipse.
In the above-mentioned technical solutions, the internal layer is cast using plain cast iron, and outer layer uses hard alloy iron casting.
The utility model hard alloy roll, including outer layer and the internal layer that is fused in outer layer, internal layer is by being fused to outer layer
Core and from core one toward both sides extend and exceed outer layer both ends driving side axle portion and slave end axle portion composition, drive
The end in side axle portion is wholely set the clutch section for passing on driving torque, clutch section have straight first end face and
A pair of the flat breach faces engaged with drive mechanism, the end of slave end axle portion are integrally formed with convex shaped part, and convex shaped part has flat
Straight second end face, the outer surface of outer layer are provided with clad, and clad is embedded with high hardness alloy powder, and the appearance of clad
Face has equally distributed laser alloying point, by the setting of clad, avoids roll huge caused by diameter reduction is scrapped
It is big to waste, material and the energy resource consumption of sandblasting process are saved, saves production cost and social resources.
Brief description of the drawings
Fig. 1 is the utility model section schematic diagram.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
