Abstract
The utility model relate to an abrasion-resistant tooth arc circular scraps-containing inclined grain thread rolling wheel which comprises a thread rolling wheel body (1). Tooth grains (4) are arranged on the outer surface of the thread rolling wheel body (1) and are arranged in the axial direction perpendicular to a center hole (2). The tooth grains (4) are divided into tooth tops (5) and tooth roots (6), the tooth tops (5) are circular arcs protruding upwards, and a scraps-containing groove (8) is arranged at the bottoms of the tooth roots (6), a coating (7) is arranged on the outside of the tooth grains (4), and the coating (7) is made of titanium. The abrasion-resistant tooth arc circular scraps-containing inclined grain thread rolling wheel is good in abrasion resistance, prolongs service life, simultaneously reduces production cost, is small in friction force and ensures bolt quality. Surplus waste scraps produced in the machining process can be collected by a waste scraps tank.
Description
(1) technical field
The utility model relates to a kind of cylindrical die roll, relates in particular to a kind of wear-resisting crest circular arc and holds bits 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, bolt and wear-resisting crest circular arc hold the long-term friction of bits twill cylindrical die roll, easily damage, 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 use, and has shortened service life; In the process of bolt, can produce unnecessary scrap at cylindrical die roll, affected to a certain extent the processing effect of bolt, the bolt poor quality who produces.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of wearability is good, the stressed less and wear-resisting crest circular arc that can collect unnecessary scrap of friction holds bits twill cylindrical die roll.
The purpose of this utility model is achieved in that
A kind of wear-resisting crest circular arc holds bits 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, the outer surface of described cylindrical die roll body is provided with the tooth line, 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, described crest is the circular arc that raises up, the bottom of described root of the tooth is provided with chip pocket, and the outside of described tooth line is provided with coating, and the material of described coating is titanium.
The wear-resisting crest circular arc of the utility model holds bits twill cylindrical die roll, and 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 crest circular arc of the utility model holds bits twill cylindrical die roll and scribbles titanium layer in the tooth line outside, has increased wearability, can prolong the service life that wear-resisting crest circular arc holds bits twill cylindrical die roll, has also reduced production cost simultaneously; Crest adopts the circular arc design in addition, rubs in process of production stressed less, has prolonged the service life of cylindrical die roll; The bottom of root of the tooth is provided with the scrap groove, can be collected in the unnecessary scrap that produces in the process of processing, has guaranteed the quality of bolt.

(5) specific embodiment
Referring to Fig. 1～Fig. 3, the wear-resisting crest circular arc of the utility model holds bits twill cylindrical die roll, 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, and described tooth line 4 is along the axial direction layout perpendicular to centre bore 2, and 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 bottom of described root of the tooth 6 is provided with chip pocket 8, and the outside of described tooth line 4 is provided with coating 7, and the material of described coating 7 is titanium.
The wear-resisting crest circular arc of the utility model holds bits twill cylindrical die roll and scribbles titanium layer in the outside of tooth line 4, has increased wearability, can prolong the service life that wear-resisting crest circular arc holds bits twill cylindrical die roll, has also reduced production cost simultaneously; Crest 5 adopts the circular arc design in addition, rubs in process of production stressed less, has prolonged the service life of cylindrical die roll; Be provided with chip pocket 8 in the bottom of root of the tooth 6, can be collected in the unnecessary scrap that produces in the bolt process, guaranteed the quality of bolt.
Claims (2)
1. a wear-resisting crest circular arc holds bits twill cylindrical die roll, 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 bottom of described root of the tooth (6) is provided with chip pocket (8), the outside of described tooth line (4) is provided with coating (7), and the material of described coating (7) is titanium.
