Device for Processing of Materials by Cutting and Cutting Unit with Oscillating Cutting Knife and Variable Cutting Angle of Inclination
A device for cutting material on a supporting surface has at least one cutting unit, which can be motor-driven in a controlled manner above and across the supporting surface in a direction of an X- and Y-axis of a Cartesian coordinate system that is parallel to the material supporting surface. The at least one cutting unit comprises an oscillation drive and a cutting knife. The oscillation drive sets the cutting knife into linear oscillations having an oscillation axis that is perpendicular to an advancing direction of the cutting knife. For changing an angle of inclination of the oscillation axis with respect to the material supporting surface, the oscillation drive with the cutting knife is pivotable around a pivot axis that is parallel to the material supporting surface. The oscillation drive comprises an electric motor having a rotary drive shaft that is parallel to the material supporting surface. The rotary axis of the rotary drive shaft is aligned with the pivot axis.
Device for processing of materials by cutting and cutting unit with oscillating cutting knife and variable cutting angle of inclination
A device for the cutting of material on a plane material supporting surface, the device having at least one cutting unit which can be motor-driven in a controlled manner above the material supporting surface in the direction of the X- and Y-axis of a Cartesian coordinate system that is parallel to the material supporting surface, and having an oscillation drive and a cutting knife, wherein the oscillation drive sets the cutting knife into linear oscillations along an oscillation axis that is perpendicular to the advancing direction of the cutting knife. The cutting knife is pivotable around a pivot axis that is parallel to the material supporting surface and is aligned with the rotary axis of a rotary drive shaft of an electric motor of the oscillation drive.
HANDHELD PUNCH TOOL
A handheld punch tool including a housing, a motor, and a transmission configured to be driven by a motor shaft. The transmission has a crankshaft and a reciprocating shaft mounted to the crankshaft. The handheld punch tool further includes a bit holder configured to be driven by the crankshaft and to retain a tool bit to form a pilot hole in a workpiece to be cut in response to rotation of the crankshaft and the bit holder. Moreover, the handheld punch tool includes a die holder, a die, and a punch. The die and the die holder define a feed slot therebetween for receiving the workpiece to be cut. The punch is configured to be driven by the reciprocating shaft to reciprocate within the die holder such that at least a portion of each of the die holder, the die, and the punch is insertable into the pilot hole.
