Abstract
The utility model relates to a sloping grain chip containing cylindrical die roll which comprises a cylindrical die roll body (1) and a center hole (2). A key groove (4) is disposed on the edge of the center hole (2). The cross section of the cylindrical die roll body (1) is in a circular ring shape. Tooth grains (4) are arranged on the outer surface of the cylindrical die roll body (1). The tooth grains (4) are sloping grains and are arranged along the direction perpendicular to the axial direction of the center hole (2). The tooth grains comprise tooth tops (5) and tooth roots (6). The bottom portion of each tooth root (6) is provided with a chip containing groove (7) so that unnecessary chips generated in the machining process can be collected, and quality of bolts is guaranteed.
Description
(1) technical field
The utility model relates to a kind of twill and holds the bits 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.In the process of bolt, on cylindrical die roll, can produce unnecessary scrap, influenced the processing effect of bolt to a certain extent, the bolt poor quality who is produced.
(3) summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of twill that can collect unnecessary scrap to hold the bits cylindrical die roll.
The purpose of the utility model is achieved in that
A kind of twill holds the bits cylindrical die roll, comprises cylindrical die roll body and centre bore, and said centre bore edge is provided with keyway; The cross section of said cylindrical die roll body is annular; The outer surface of said cylindrical die roll body is provided with the tooth line, and said tooth line is a twill, and 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 bottom of said root of the tooth is provided with chip pocket.
The utility model twill holds the bits cylindrical die roll, and the material of said cylindrical die roll body adopts medium carbon steel.
Compared with prior art, the beneficial effect of the utility model is:
The bottom that the utility model twill holds the root of the tooth of bits cylindrical die roll 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.
