A multi-stage incremental sheet forming system includes a forming tool, and at least one control unit in communication with the forming tool. The at least one control unit is configured to determine a convex hull of a target structure to be formed by the forming tool. The at least one control unit is further configured to operate the forming tool according to a first tool path in relation to an initial structure to form an intermediate structure having a shape based on the convex hull of the target structure. The at least one control unit is further configured to operate the forming tool according to a second tool path in relation to the intermediate structure to form one or more inward features into the intermediate structure to form the target structure.

A high-precision heavy-load numerically-controlled flanging machine comprises a machine frame, an edge pressing assembly, a flanging beam and a flanging beam transmission mechanism that comprises an inclined slide rail, an inertia block and two crank-connecting rod mechanisms; the flanging beam is provided with a driving inclined plane; the inclined slide rail is mounted on the machine frame; the inertia block is provided with two non-parallel inclined planes, wherein one inclined plane of the inertia block is slidably mounted on the inclined slide rail to form a sliding pair I, and the other inclined plane of the inertia block is in sliding fit with the driving inclined plane of the flanging beam to form a sliding pair II; cranks of the two crank-connecting rod mechanisms are hinged on the machine frame.

A method and a correspondingly configured bending machine are described, wherein a setting of the bending machine is first calculated on the basis of a mathematical model and subsequently corrected on the basis of stored data sets on previous bending operations and their correction values.

A press brake for bending workpieces includes: a fixed table beam with a lower tool holder, a displaceable press beam with an upper tool holder, wherein the press beam is formed so as to be displaceable relative to the table beam, and a graphic display for displaying information. In the displaceable press beam, a recess is formed, in which the graphic display is accommodated, wherein the graphic display has a display height and a display width.

A system includes a plurality of forming roller sets comprising an inner forming roller and an outer forming roller, each inner forming roller rotatable about an inner forming roller axis, each outer forming roller rotatable about an outer forming roller axis, each forming roller set being adjustable between an engagement configuration and a disengagement configuration, each forming roller set forming a profile on the ring component based on a forming roller set profile of the forming roller set, the system also including an actuating unit which controls the engagement and a disengagement of the forming roller sets with the ring component.

Systems and methods for bending a material to a target resultant bending parameter using a bend forming tool are disclosed. The systems and methods receive values for parameters of properties of the material and of a bending process to be performed by the bend forming tool, creating or retrieving a calibration curve relating input bending parameter and resultant bending parameter based on the values from a database of calibration curves, determining a first springback compensated input bending parameter based on the target resultant bending parameter using the calibration curve, inputting the first springback compensated input bending parameter to the bend forming tool, and in a first step of bending the material, bending the material to the first springback compensated input bending parameter by applying the bending process using the bend forming tool.

In a first step, a pulling operation is performed with respect to four tools by retaining, in an immovable state, a leftmost tool from among the four tools lined up on a tool mounting unit by means of a left ATC and by moving, toward the left ATC, a rightmost tool from among the four tools by means of a right ATC. In a second step, a movement of the right ATC is stopped when a torque of a motor for moving the right ATC in a left-right direction reaches a preset set value. The first step includes a choosing step of choosing, for the respective left and right ATCs, whether to perform the pulling operation in a state of being abutted against respective side surfaces of the tools or to perform the pulling operation in a state of being engaged with respective engagement holes of the tools.

A bending machine, in particular a swivel bending machine, is provided that defines a safety-relevant work area in which an operator of the bending machine is present during its operation, loading, unloading or the like, having a safety module comprising a safety barrier which provides a variable-size shield for the safety-relevant work area such that a shut-off state and an access state can be generated, wherein in the shut-off state access to the safety-relevant work area is at least partially restricted and wherein in the access state access to the safety-relevant work area is at least partially granted. A method is provided for processing a workpiece by means of a bending machine.

A method of aligning a flat or profiled metal sheet with preformed notches on the two sides of the metal sheet when the sheet enters into a bender or folding machine directly from a roll forming machine linked or joined to the folder. The metal sheet has to be effectively aligned on the folder before folding to avoid potential damages to the metal sheet of not being properly squared or angled on bending while reducing the times to produce the folded products. Moreover, this method according to the invention allows the metal sheet to feed directly into the folder from the rollformer without having to pass through an intermediary transfer table or aligning device/machine before entering the folder for folding or manual alignment in the folder.

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.
