Abstract
The utility model relates to a wear-resistant sloping grain thread rolling wheel, comprising a thread rolling wheel body (1) and a center hole (2). A key groove (3) is arranged at the edge of the center hole (2); the cross section of the thread rolling wheel body (1) is circular; tooth grains (4) are arranged on the outer surface of the thread rolling wheel body (1); the tooth grains (4) are sloping grains, and are arranged along an axial direction vertical with the center hole (2); each tooth grain (4) is divided into a tooth top (5) and a tooth root (6); a coating (7) is arranged at the outer side of the tooth grains (4); and the coating (7) is made of titanium. According to the wear-resistant sloping grain thread rolling wheel provided by the utility model, the titanium layer is coated at the outer side of the tooth grains, so that the wear resistance is improved; the service life of the wear-resistant sloping grain thread rolling wheel can be prolonged; and the production cost can be reduced simultaneously.
Description
(1) technical field
The utility model relates to a kind of cylindrical die roll, relates in particular to a kind of wear-resisting twill cylindrical die roll.
(2) background technology
Cylindrical die roll is to utilize the method for metal plastic deformation to roll out a kind of instrument of screw thread at screw-rolling machine, 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 wear-resisting twill cylindrical die roll damages easily, and service life is short, has increased production cost.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of wearability good wear-resisting twill cylindrical die roll.
The purpose of this utility model is achieved in that
A kind of wear-resisting twill cylindrical die roll, comprise cylindrical die roll body and centre bore, described centre bore edge is provided with keyway, the cross section of described cylindrical die roll body is annular, and the outer surface of described cylindrical die roll body is provided with the tooth line, and described tooth line is twill, described tooth line is arranged along the axial direction perpendicular to centre bore, described tooth line is divided into crest and root of the tooth, and 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 the utility model, the material of described cylindrical die roll body adopts medium carbon steel.
Compared with prior art, the beneficial effects of the utility model are:
The wear-resisting twill cylindrical die roll of the utility model scribbles titanium layer in the tooth line outside, has increased wearability, can prolong the service life of wear-resisting twill cylindrical die roll, has also reduced production cost simultaneously.
