Abstract
Pressing residue and shell are stripped from a metal-extruder disk having a pair of parallel and flat end faces at least one of which carries pressing residue or shell and an annular outer periphery extending between the end faces and carrying shell. First the disk and a blade are relatively displaced such that the blade sweeps across one of the faces and scrapes any press residue or shell therefrom. Then the disk is rotated about an axis perpendicular to the end faces while a plurality of angularly offset rollers are pressed radially against the shell carried on the outer periphery while the disk is rotating to radially deform the shell and separate it from the outer periphery. The shell separated from the outer periphery is then transported away from the disk.
Claims9
A method of stripping pressing residue and shell from a metal-extruder disk having
- a pair of parallel and flat end faces at least one of which carries pressing residue or shell and
- an annular outer periphery extending between the end faces and carrying shell,
- the method comprising the steps of:
- relatively displacing the disk and a blade with the blade sweeping across one of the faces and scraping any press residue or shell therefrom;
- rotating the disk about an axis perpendicular to the end faces;
- pressing a roller radially of the axis against the shell carried on the outer periphery while the disk is rotating to radially deform and compress the shell against the disk at the roller and thereby free the shell from the outer periphery adjacent the roller;
- and
- thereafter axially relatively displacing the radially deformed and compressed shell and the disk and thereby separating the shell from the disk.
An apparatus for stripping pressing residue and shell from a metal-extruder disk having
- a pair of parallel and flat end faces at least one of which carries pressing residue or shell and
- an annular outer periphery extending between the end faces and carrying shell,
- the apparatus comprising:
- a frame carrying at least one blade;
- means for displacing the disk and blade so that the blade sweeps across one of the faces and scrapes any press residue or shell therefrom;
- means for positioning the disk centered on a system axis perpendicular to the end faces;
- means for rotating the disk about the system axis;
- a roller engageable radially against the shell carried on the outer periphery;
- means for pressing the roller radially against the shell carried on the outer periphery while the disk is rotating to radially deform and compress the shell against the disk at the roller and thereby free the shell from the outer periphery adjacent the roller;
- and
- means for axially relatively displacing the freed shell and the disk to separate the shell from the disk.
