US 4,119,015 A · Billet milling equipment

Abstract

Billet milling equipment including first frames which are laid on a traveling path of a billet, a pair of upper and lower clamping frames which are movable so as to follow a deformation of the billet and which are installed on the first frames, and milling cutter units which normally follow a surface of the billet to be cut in correspondence with the deformation of the billet and which are installed on the clamping frames in a manner to be capable of advancing or retreating relative to the surface to-be-cut. On the basis of a signal from a flaw detector, a milling cutter of the milling cutter unit which is following the deformation of the billet is rotated in pressed contact with the surface to-be-cut of the billet, whereby a flaw is removed by the cutting.

Dependent claims

Billet milling equipment for cutting and removing a flaw by rotating a milling cutter in pressed contact with a surface to-be-cut of a billet, which comprises:

first frames forming a traveling path through which said billet passes,
a pair of upper and lower clamping frames which are moveable so as to follow up a deformation of said billet and which are installed on said first frames,
a first and second milling cutter unit, which normally follow up the surface to-be-cut of said billet in correspondence with the deformation of said billet, installed on said upper and lower clamping frames, respectively, means for automatically advancing and retreating said first and second milling cutter unit relative to said surface to-be-cut wherein driving means for bestowing feed of said billet are installed on one of said clamping frames, and driven means pairing with and operably connected to said driving means is disposed on the other of said clamping frames and wherein said clamping frames are installed on said first frames by cylinder members.
