US 2012/0234072 A1 · Apparatus having a plurality of cold rolling installations

Abstract

An apparatus is disclosed having a plurality of cold rolling installations which each have a roll stand movable along a linear path and having at least one roll which is fixed rotatably to the roll stand, a drive connected to the roll stand and having an electric motor so adapted that the roll stand is drivable in an oscillating movement along the linear path, and a feed clamping saddle for feeding a blank. The apparatus has an electric control having at least two control outputs, wherein each control output is connected to the electric motor of the drive of a roll stand and wherein the control is so adapted that in operation of the apparatus it so controls the electric motors that they drive at least two of the roll stands with an adjustable phase displacement between the oscillating movements of the roll stands.

Apparatus having

a plurality of cold rolling installations which each have
a roll stand movable along a linear path and having at least one roll which is fixed rotatably to the roll stand,
a drive connected to the roll stand and having an electric motor so adapted that the roll stand is drivable in an oscillating movement along the linear path, and
a feed clamping saddle for feeding a blank,
wherein the apparatus has an electric control having at least two control outputs,
wherein each control output is connected to the electric motor of the drive of a roll stand, and
wherein the control is so adapted that in operation of the apparatus it so controls the electric motors that they drive at least two of the roll stands with an adjustable phase displacement between the oscillating movements of the roll stands.
