Title:

NOVEL METHOD FOR SYNCHRONOUS AND SPECIFIED-LENGTH CUTTING OF CONTINUOUSLY-FORMED MATERIALS BY MULTIPLE CUTTING MECHANISMS CONNECTED IN SERIES

Document Type and Number:

WIPO Patent Application WO/2017/121013

Kind Code:

A1

Abstract:

A method for synchronous and specified-length cutting of continuously-formed materials by multiple lathes connected in series in production lines of continuously-formed materials, such as steel pipes and steel sections. A synchronous and specified-length cutting machine having multiple lathes connected in series is provided with two or more lathes that are separately equipped with a cutting tool (7), i.e., a lathe (1) and a lathe (2). The lathes are installed in series on a rail parallel to a material and are driven by respective driver means (6) or (5) to move back and forth according to a set procedure; in the case that the speed of the lathes is synchronous with that of the material (3), the cutting tool (9) or (7) on the lathes cuts the material according to a specified length. The cutting machine can be adapted to high-speed production lines, allows a small minimum specified length, possesses cutting tools having a long service life, and achieves smooth cuts.
