A planar workpiece machining device has an upper tool and a lower tool that are movable toward each other in a reciprocation direction and in the opposite direction to machine a workpiece arranged therebetween. The upper tool has a clamping shaft, an upper main body, and a tool body arranged opposite the clamping shaft on the main body and having an upper bending edge. The lower tool has a lower main body, on which a counter tool body having a lower bending edge and a counter holder are provided. The lower bending edge is oriented facing the counter holder. The upper bending edge is stationary to the upper main body, and the lower bending edge is stationary to the lower main body. The upper bending edge is associated with an undercut on the tool body and the lower bending edge is associated with an undercut on the counter tool body.

Machining planar workpieces

A machine tool for machining planar workpieces includes an upper tool, a lower tool, a machine frame, and a controller. The upper tool is movable with a stroke movement along a stroke axis by a stroke drive device in a direction towards a workpiece and in the opposite direction and positionable with an upper traversing movement along an upper positioning axis by a motor drive assembly. The lower tool is aligned with the upper tool and is positionable with a lower traversing movement along a lower positioning axis by a motor drive assembly. The upper and lower tools are movable in a frame interior of the machine frame. The motor drive assemblies can be controlled by the controller. The upper and lower traversing movements can be controllable independently of each other. The upper tool can be controlled with the upper traversing movement and the stroke movement in a superposed manner.

Processing planar workpieces

A tool includes an upper tool having a clamping shaft and an upper main body that lie on a common positioning axis, a processing tool opposite the clamping shaft that has at least one processing edge that extends at least partially along a holding-down surface of the main upper body, a lower tool having a lower main body with a rest surface for the workpiece and a lower positioning axis oriented perpendicular to the rest surface, a counter tool body on the lower main body, the counter tool body having a counter roller with at least one counter edge opposite the at least one processing edge of the processing tool, and a processing device adjacent to the at least one counter edge that has at least one curved counter surface oriented in the longitudinal direction of the processing edge of the processing tool.

Tools, machines, and methods for processing planar workpieces

Tools for machining planar workpieces are provided that include an upper tool, an upper main body, and at least one tool body on the upper main body having a cutting edge. The tools further include a lower tool having a lower main body with a rest surface for the workpiece and a positioning axis oriented perpendicular to the rest surface, at least one counter tool body on the lower main body that has a counter cutting edge that is a closed contour. The cutting edge of the at least one tool body has a cutting contour that corresponds to the closed contour of the at least one counter tool body, and at least one group of at least two counter tool bodies on the lower tool can be associated with the closed contour of the least one tool body.

Tools, machines, and methods for machining planar workpieces

A method for multiple-stroke slotting of planar workpieces includes positioning a workpiece relative to a slotting tool having a punch and a die, moving the punch and the die relative to one another, moving the slotting tool and the workpiece relative to one another, slotting a workpiece by a slot length during a sectioning slot stroke and at least one subsequent slotting stroke in a sectioning phase, and performing strokes in form of slotting strokes and at least one trimming stroke during the relative movement of the punch and the die in a working phase. The subsequent slotting stroke is performed prior to the trimming stroke, and the slot length exceeds a maximum attainable slot length during the trimming stroke. The workpiece and the slotting tool are moved relative to one another by at least one feed movement between the strokes.

Multiple stroke slotting of planar workpieces

A machine for machining, such as cutting and/or forming, planar workpieces has an upper tool and a lower tool that are movable toward each other to machine a workpiece arranged therebetween. The upper tool includes at least one cutting tool having at least one cutting edge and a clamping shaft. The lower tool includes a main body having a support surface for the workpiece. The support surface has an opening associated with an inner counter cutting edge. The lower tool has a positioning axis and at least one outer counter cutting edge provided outside of the opening and associated with the support surface. The outer counter cutting edge is aligned with an outer face of the support surface. A distance of the outer counter cutting edge from the position axis and a distance of the inner counter cutting edge from the position axis deviate from each other.

A tool for machining a planar workpiece, comprising an upper tool having a clamping shaft and an upper main body that lie on a common positioning axis, a tool body arranged opposite to the clamping shaft on the upper main body, the tool body comprising a bending edge, and a lower tool having a lower main body that receives a rotational body that is rotatable around an axis of rotation running in a direction of the bending edge of the tool body, wherein the upper tool and the lower tool are movable towards and away from each other in a stroke direction for machining the workpiece arranged therebetween, and wherein the upper main body defines a projection surface that is perpendicular to the positioning axis and the bending edge of the tool body is adjacent tangentially to the projection surface or is outside the projection surface.

A tool includes first and second tool parts that move toward one another, at least one processing device provided on the first tool part, and at least two counter devices provided on the second tool part. The processing device and the counter devices are rotatable relative to one another about at least one positioning axis, and the counter devices are aligned relative to one another along a direction of relative rotational movement of the processing device and the counter devices. The processing device and a first counter device are allocated to one another by at least a first defined processing parameter, and the processing device and a second counter device are allocated to one another by at least a second defined processing parameter. The first processing parameter is different than the second processing parameter.
