Investigation and improvement of round bars waste-free cutting process

Abstract

Purpose: development of a new round bars waste-free cutting process and designing of respective equipment. The work develops a rational scheme for round bars waste-free cutting process, investigates a stress-deformed state of metal in cutting according to this scheme and offers a unified dynamic model of the process with the use of chears. The results of the investigation include the development of a round bars waste-free cutting process with eccentric torsion, offers torsional shearing devices of several designs and provides recommendations on qualitative shearing of metals possessing different mechanical properties. The proposed shears have undergone the production tests and are adopted for use at Rustavi Metallurgical Plant. Field of application: machine-building and metallurgical plants, design agenciesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
