20200047301 · 2020-02-13 ·

A machine integrated positioning system shows an operator where to place a raw part in the press brake or other machinery. Further, the operator is informed if the dimensions associated with the raw part are, or are not, correct to produce the planned finished part. The operator is visually shown how the raw part is to be oriented. The operator is informed if the raw part is right-side-up, along with other pre-final placement information. If these and other conditions are not met, the machine integrated positioning system may prevent the press brake and other machinery from cycling.

TABLE ASSEMBLY FOR PRESS BRAKE SYSTEM

A table assembly is used to support a workpiece to facilitate bending of the workpiece. The table assembly is attached to a press brake system and include a base and a clamp. The clamp is movable relative to the base to enable placement of the workpiece onto the base, and the clamp secures the workpiece to the base to block relative movement between the workpiece and the press brake system without additional user operations. The workpiece is secured via the table assembly without a manual force (e.g., to hold the workpiece in place) while the press brake system operates to bend the workpiece. The table assembly reduces, limits, or eliminates certain user operations during metalworking. The table assembly improves user experience (e.g., reduce an amount of manual labor) and/or efficiency associated with press brake operations.

BENDING PRESS AND BENDING METHOD

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.
