The utility model content

The purpose of this utility model is, the roller that provides a kind of multi-functional stabilizer to use; Cutting edge on this roller applies postwelding by the high hardness alloy welding rod and forms after grinding, adopts not only scuff resistance height of cutting edge that the utility model makes, and has good stability, and advantage such as at the bottom of the cost of manufacture can overcome the deficiencies in the prior art.

The technical solution of the utility model; The roller that a kind of multi-functional stabilizer is used, comprise columniform roller 1, be provided with axis hole 2 at the center of roller 1, the lower end of roller 1 is a cone 3, on the surface of roller 1, be provided with left-hand screw groove 4 and annular groove 5, left-hand screw groove 4 becomes to press the projection 6 of the inclination of helix distribution with annular groove 5 with the surface segmentation of roller 1, is fixed with high hardness alloy material layer 7 on the surface of projection 6.

The thickness that is fixed on the high hardness alloy material layer 7 on the every projection 6 is that the front side is greater than rear side.

On cone 3, also be provided with high hardness alloy material layer 7.

The circumscribed circle tangent line of projection 6 front side high hardness alloy material layers 7 and the angle α of projection 6 front sides and rear side line are 3～15 degree

The quantity of left-hand screw groove 4 and annular groove 5 is 3～16 roads.

Compared with the prior art, the utility model connects the high hardness alloy material by the mode that adopts welding in roller surface, high hardness alloy material to welding carries out grinding again, make it become the cutting edge of stabilizer roller surface, and the high hardness alloy material directly applies postwelding by welding rod and forms, the cutting edge that adopts this method to make not only can guarantee the bonding strength of high hardness alloy material and roller, and the connected mode of high hardness alloy material and roller is also very simple; Not only mouth is sharp for the cutting edge of Xing Chenging simultaneously, and has very strong abrasion resistance and hardness, can improve the application life and the result of use of stabilizer; But play cushioning effect at the cone pair roller of roller end portions and the bump of rock, can further improve the application life of cutting edge.When the mode of adopt applying weldering connects during the high hardness alloy material, applying the high hardness alloy material thickness that is welded on the roller there are differences, this welding method can be when the grinding cutting edge, reduce the processing capacity of grinding, produce the time spent thereby can further save, reduce production costs, improve the market competitiveness of enterprise; Therefore having the utlity model has excellent popularization is worth and practical value.
