Abstract

The invention discloses a tube blank feeding system of a multiroll large-caliber cold pilgering mill, belonging to the field of seamless steel tube manufacture in the metallurgy industry. The tube blank feeding system comprises a lathe bed. The lathe bed comprises two lead screw front support seats and two bases, the two bases are also respectively connected with lead screw back support seats, the lead screw front support seat and the lead screw back support seat which are arranged at the same side are respectively internally provided with a lead screw, the back end of each lead screw is respectively connected with a direct current motor through a reducer, and each direct current motor is respectively provided with an encoder; each lead screw is respectively connected with at least three first lead screw nuts, and a tube blank bracket is fixed between the first lead screw nuts of each pair of lead screws; and a tube blank chuck is arranged at the back end of the lathe bed and comprises a chuck body, second lead screw nuts are respectively fixed at the left end and the right end of the chuck body and are respectively connected to the corresponding lead screws, a plug is arranged in the chuck body, a plug loading and unloading mechanism is arranged at the front end below the tube blank chuck, and an articulated core rod bracket is arranged below the middle part of the lathe bed. The invention has the advantages of compact structure, uniform feeding and favorable control effect.

Description

technical field [0001] The invention relates to a billet feeding system, which belongs to the technical field of seamless steel pipe manufacturing in the metallurgical industry, in particular to a billet feeding system on a multi-roller large-diameter cold-rolled pipe mill. Background technique [0002] The cold rolling mill is the main mechanical equipment commonly used to produce precision seamless pipes at home and abroad, and the feeding mechanism is one of the most important components in the cold rolling mill. During the rolling process, it intermittently feeds the tube blank to the rolling area, and it is required to complete the feeding of the tube blank only when the roll is out of contact with the tube blank sleeved outside the mandrel during work. The feeding amount of the billet can be adjusted appropriately according to the needs, and it is also required that when the billet is about to be rolled, the chuck of the billet can be quickly returned to the original p...
