In a step-bending die device, the die has a horizontal surface and an inclined surface, forming a semicircular groove with a semicircular cross section along a longitudinal direction on the horizontal surface and installing a semicircular rotary blade rotatably in the semicircular groove. The punch has a horizontal surface and an inclined surface, forming a semicircular groove with a semicircular cross section in a longitudinal direction on the horizontal surface and installing a semicircular rotary blade rotatably in the semicircular groove. Vertical notches at positions changing from the horizontal surfaces to the inclined surfaces are formed in longitudinal directions in the die and the punch so that top portions of the die and the punch are formed. The punch is assembled so that the horizontal surface of the punch faces the inclined surface of the die, and the inclined surface of the punch faces the horizontal surface of the die.

A method for making a bent razor blade is disclosed. The method includes: providing an elongated strip of stainless steel that can be 0.076 mm thick; hardening the strip; providing a cutting edge along an edge of the strip and providing coating(s) on the cutting edge. The stainless steel has a carbon content less than 0.60% and preferably between 0.45% and 0.55% by weight. The strip is separated lengthwise into discrete razor blades. The bent portion of the razor blade is then formed using a swivel bending process.

A tool-changing unit for a production plant for forming sheet metal using a bending operation. The tool-changing unit includes a tool-holding device having a carrier body and a number n of tool-holding modules arranged directly next to one another and held on the carrier body. Each one of the tool-holding modules includes a first coupler and a first actuating device cooperating therewith as a component of a coupling device, wherein the first coupler can be brought into coupling engagement and out of coupling engagement with an individual clamping jaw of a clamping jaw set. Moreover, a production plant has the tool-changing unit and the clamping jaw a method changes tools.

A method of forming a vehicle panel includes deforming a sheet metal workpiece between stamping tools to form a first and second edges that converge at a corner of the workpiece's main surface. The first edge is defined by a junction of the main surface and a first flange. The second edge is defined the main surface and a second flange. Forming the first and second edges includes deforming the workpiece so that the second flange has a first region bent to a first angle relative to the main surface and an unwinding region bent to an angle that unwinds from the first region as the second flange approaches the corner. The method includes deforming the workpiece between a second set of stamping tools that deform the first flange and the unwinding region of the second flange until the first and second flanges are bent greater than 90?.

A forming operation on a workpiece clamps the workpiece between a first clamping jaw with a first shaping edge, and an adjustable second clamping jaw with a second shaping edge so that a portion projects between the shaping edges and afterwards a bending edge of an adjustable bending bar is guided at a distance past the shaping edges, whereby the portion of the workpiece is angled away in relation to the part of the workpiece that is clamped between the clamping jaws. The bending edge is guided on angling along a straight path of movement of the bending edge, and after the bending edge has passed the shaping edges, the shaping edges are adjusted along an adjustment path which approaches the path of movement of the bending edge.
