Abstract
The invention relates to a crest arc abrasion-resisting inclined pattern cylindrical inclined pattern cylindrical die roll which comprises a cylindrical die roll body (1). Tooth patterns (4) are formed in the outer surface of the cylindrical die roll body (1), the tooth patterns are inclined patterns, the teeth patterns (4) are arranged in the direction perpendicular to the axial direction of a central hole (2), the teeth patterns are divided into a crest (5) and a stump (6), the crest (5) is in an upward-protruding arc shape, a coating layer (7) is arranged at the outer side of the tooth patterns (4), and the coating layer (7) is made of titanium materials. According to the crest arc abrasion-resisting inclined pattern cylindrical die roll, due to the fact that the titanium layer is arranged on the outer sides of the tooth patterns (4), abrasion-resisting performance is improved, the service life of the crest arc abrasion-resisting inclined pattern cylindrical die roll is prolonged, and production cost is reduced at the same time; in addition, due to the fact that the arc-shaped design is adopted, friction stress is low in the production process, and the service life of the cylindrical die roll is prolonged.
Description
(1) technical field
The present invention relates to a kind of cylindrical die roll, relate in particular to the wear-resisting twill cylindrical die roll of a kind of crest circular arc.
(2) background technology
Cylindrical die roll is on screw-rolling machine, to utilize the method for metal plastic deformation to roll out a kind of instrument of screw thread, is applicable to process high-strength bolt.The wearability of cylindrical die roll is bad at present, and in the process of bolt, the long-term friction of bolt and the wear-resisting twill cylindrical die roll of crest circular arc, easily damages, and service life is short, has increased production cost; The crest of cylindrical die roll is flat-top in addition, rubs in process of production stressed larger, and easily impaired, then cylindrical die roll just can not have been used, and has shortened service life.
(3) summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of wearability the good and wear-resisting twill cylindrical die roll of stressed less crest circular arc that rubs.
The object of the present invention is achieved like this:
The wear-resisting twill cylindrical die roll of a kind of crest circular arc, comprise cylindrical die roll body and centre bore, described centre bore edge is provided with keyway, and the cross section of described cylindrical die roll body is annular, and the outer surface of described cylindrical die roll body is provided with tooth line, described tooth line is twill, described tooth line is along the axial direction layout perpendicular to centre bore, and described tooth line is divided into crest and root of the tooth, and described crest is the circular arc raising up, the outside of described tooth line is provided with coating, and the material of described coating is titanium.
The wear-resisting twill cylindrical die roll of crest circular arc of the present invention, the material of described cylindrical die roll body adopts medium carbon steel.
Compared with prior art, the invention has the beneficial effects as follows:
The wear-resisting twill cylindrical die roll of crest circular arc of the present invention scribbles titanium layer in tooth line outside, has increased wearability, can extend the service life of the wear-resisting twill cylindrical die roll of crest circular arc, has also reduced production cost simultaneously; Crest adopts circular arc design in addition, rubs in process of production stressed less, has extended the service life of cylindrical die roll.

(5) specific embodiment
Referring to Fig. 1～Fig. 3, the wear-resisting twill cylindrical die roll of crest circular arc of the present invention, comprise cylindrical die roll body 1 and centre bore 2, described centre bore 2 edges are provided with keyway 3, the material of described cylindrical die roll body 1 adopts medium carbon steel, the cross section of described cylindrical die roll body 1 is annular, the outer surface of described cylindrical die roll body 1 is provided with tooth line 4, described tooth line 4 is twill, described tooth line 4 is arranged along the axial direction perpendicular to centre bore 2, described tooth line 4 is divided into crest 5 and root of the tooth 6, the circular arc of described crest 5 for raising up, the outside of described tooth line 4 is provided with coating 7, the material of described coating 7 is titanium.
The wear-resisting twill cylindrical die roll of crest circular arc of the present invention scribbles titanium layer in the outside of tooth line 4, has increased wearability, can extend the service life of the wear-resisting twill cylindrical die roll of crest circular arc, has also reduced production cost simultaneously; Crest 5 adopts circular arc design in addition, rubs in process of production stressed less, has extended the service life of cylindrical die roll.
Claims (2)
1. the wear-resisting twill cylindrical die roll of crest circular arc, comprise cylindrical die roll body (1) and centre bore (2), described centre bore (2) edge is provided with keyway (3), the cross section of described cylindrical die roll body (1) is annular, the outer surface of described cylindrical die roll body (1) is provided with tooth line (4), described tooth line (4) is twill, described tooth line (4) is arranged along the axial direction perpendicular to centre bore (2), described tooth line (4) is divided into crest (5) and root of the tooth (6), it is characterized in that: the circular arc of described crest (5) for raising up, the outside of described tooth line (4) is provided with coating (7), the material of described coating (7) is titanium.
