Abstract

Apparatus for the continuous, chipless separation of individual, identical pieces from a solid round workpiece, includes at least two cutting rollers, cooperating with one another, for separating and rolling the workpiece. Each of the cutting rollers is defined by a separating portion and has a coil, with the height of the coil of one cutting roller being equal or slightly greater than the radius of the workpiece in the separating portion, and with the coil of the other cutting roller so configured as to eliminate a collision in the separating portion with the coil of the one cutting roller.

Claims22

Dependent claims

Apparatus for the continuous, chipless separation of individual, identical disk-shaped blanks or bolts from a round bar-shaped workpiece, comprising:

an inlet gutter receiving a round bar-shaped workpiece which is defined by a radius;
a separating and rolling device;
a feed device for advancing the workpiece from the inlet gutter to the separating and rolling device and imparting a rotation upon the workpiece;
said separating and rolling device having at least two cutting rollers for processing the workpiece, each of the cutting rollers having a coil and including a separating portion, wherein the coil of at least one of the cutting rollers has in the separating portion a height which is equal or slightly greater than the radius of the workpiece, wherein the coil of the other one of the cutting rollers is so configured as to avoid in the separating portion a collision with the coil of the one of the cutting rollers;
a guiding gib for application with the at least two cutting rollers.

2 more elements

A separating and rolling device for use in an apparatus for the continuous, chipless separation of individual, identical pieces from a solid round workpiece, comprising at least two cutting rollers cooperating with one another for separating and rolling a solid round workpiece defined by a radius, each of the cutting rollers defined by a separating portion and having a coil, wherein the coil of one of the cutting rollers has in the separating portion a height which at a minimum is equal to the radius of the workpiece, wherein the coil of another one of the cutting rollers is so configured as to eliminate a collision in the separating portion with the coil of the first one of the cutting rollers.
