Problems solved by technology
At present, the tooth depth of the thread rolling wheel is the same, that is, the depth from the top of the tooth to the root of the tooth is the same, so that the strength of the rolled screw is not high, and it is easy to break; in addition, the wear resistance of the thread rolling wheel is not good. During the processing of bolts, the long-term friction between the bolts and the wear-resistant thread rolling wheel is easy to be damaged, the service life is short, and the production cost is increased; It affects the processing effect of the bolts, and the quality of the produced bolts is not good

The invention relates to an abrasion-resistant straight-grain cylindrical die roll with guide angles and a scrap accommodating function. The abrasion-resistant straight-grain cylindrical die roll comprises a cylindrical die roll body (1). At least two threads (4) are arranged on the outer surface of the cylindrical die roll body (1), each thread (4) is perpendicular to the axial direction of a center hole (2) and is divided into a crest (5) and a root (6), a scrap accommodating groove (8) is formed in the bottom of each root (6), the guide angles alpha are formed among straight lines where the multiple crests (5) are located and straight lines where the multiple roots (6) are located, and coatings (7) are arranged on the outer sides of the threads (4) and are made of titanium. The abrasion-resistant straight-grain cylindrical die roll with the guide angles and the scrap accommodating function has the advantages that the abrasion-resistant straight-grain cylindrical die roll has the certain guide angles, so that a screw rolled by the abrasion-resistant straight-grain cylindrical die roll is high in strength and good in quality and is not easy to break; the abrasion-resistant straight-grain cylindrical die roll is good in abrasion resistance, the service life of the abrasion-resistant straight-grain cylindrical die roll is prolonged, and the production cost is lowered; redundant scraps generated in a machining procedure can be collected by the scrap accommodating grooves, so that the quality of a bolt can be guaranteed.
Description
(1) Technical field [0001] The invention relates to a thread rolling wheel, in particular to a wear-resistant chip-holding ruled thread rolling wheel with a guide angle. (2) Background technology [0002] The thread rolling wheel is a tool that uses metal plastic deformation to roll out threads on a thread rolling machine, and is suitable for processing high-strength bolts. At present, the tooth depth of the thread rolling wheel is the same, that is, the depth from the top of the tooth to the root of the tooth is the same, so that the strength of the rolled screw is not high, and it is easy to break; in addition, the wear resistance of the thread rolling wheel is not good. During the processing of bolts, the long-term friction between the bolts and the wear-resistant thread rolling wheel is easy to be damaged, the service life is short, and the production cost is increased; It affects the processing effect of the bolts, and the quality of the produced bolts is not good.
