Abstract
The utility model relates to a wear-resistant thread rolling wheel which comprises a wear-resistant thread rolling wheel body (1) and a center hole (2), wherein a key slot (3) is formed in the edge of the center hole (2); the cross section of the wear-resistant thread rolling wheel body (1) is circular ring-shaped; threads (4) are formed on the outer surface of the wear-resistant thread rolling wheel body (1); the threads (4) are straight threads and are arranged in the direction perpendicular to the axial direction of the center hole (2); each thread (4) is divided into a thread top (5) and a thread root (6); a coating (7) is arranged on the outer side of the thread (4); and the coating (7) is made from titanium. According to the wear-resistant thread rolling wheel, the titanium coatings are arranged on the outer sides of the threads, so that the wear resistance is improved, the service life of the wear-resistant thread rolling wheel is prolonged, and meanwhile the production cost is lowered.
Description
(1) technical field
The utility model relates to a kind of cylindrical die roll, relates in particular to a kind of wear-resisting cylindrical die roll.
(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 the processing 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 cylindrical die roll damages easily, and service life is short, has increased production cost.
(3) summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of wearability good wear-resisting cylindrical die roll.
The purpose of the utility model is achieved in that
A kind of wear-resisting cylindrical die roll comprises wear-resisting cylindrical die roll body and centre bore, and said centre bore edge is provided with keyway; The cross section of said wear-resisting cylindrical die roll body is annular, and the outer surface of said wear-resisting cylindrical die roll body is provided with the tooth line, and said tooth line is a straight burr; Said tooth line is arranged along the axial direction perpendicular to centre bore; Said tooth line is divided into crest and root of the tooth, and the outside of said tooth line is provided with coating, and the material of said coating is a titanium.
The wear-resisting cylindrical die roll of the utility model, the material of said wear-resisting cylindrical die roll body adopts medium carbon steel.
Compared with prior art, the beneficial effect of the utility model is:
The wear-resisting 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 cylindrical die roll, has also reduced production cost simultaneously.
