A press brake for bending a workpiece that includes a movable ram and a support beam. The press brake includes a backgauge that has an arm with a plurality of fingers for grasping the workpiece. The arm is mounted to an arm support that is mounted on a carriage that is mounted on a backgauge support frame. The arm is configured to swing relative to the arm support in a plane perpendicular to the carriage from a position projecting away from one side of the carriage to a position projecting away from the other side of the carriage. The carriage is configured to rotate 180 degrees so that opposite sides of the workpiece may be positioned under the ram to thereby allow for bending operations to be performed on opposite sides of the workpiece without removing the workpiece from the backgauge.

A forming method for a vehicle body member may include a tube making process of forming a steel pipe by welding a steel plate coil; a non-circular tube making process of primary preforming the steel pipe formed in the tube making process so as to have a cross section of a predetermined shape; a bending process of bending and secondarily preforming the steel pipe preformed firstly in the non-circular tube making process; and a hot stamping process of heating the secondarily preformed steel pipe, inserting the heated steel pipe into a mold to form a desired shape, and then, quenching the heated steel pipe to form a vehicle body member, thereby easily forming a vehicle body member having high rigidity.

The invention relates to a metal sheet storage device (21) with a housing (22), having a housing upper face (23), and with two support devices, each of which has a support plane (35, 45) for supporting metal sheets (17) or bending parts (19). The support planes (35, 45) of the support devices can be moved relative to the housing upper face (23) of the housing (22) of the metal sheet storage device (21). The invention further comprises a bending device with a bending press and such a metal sheet storage device (21).

The invention relates to a bending tool (1) comprising a tool body (2) having an upper (3) and an opposite lower end region (4), wherein an attachment extension (5) is configured in the upper end region (3), and a working tip (6) is configured in the lower end region (4). A tool identification marker (11) is disposed in the tool body (2), and a communication interface (9) is disposed in the attachment extension (5) on at least one side surface (8) and not projecting beyond it, which interface is connected with the tool identification marker (11) by way of a connection line (10). An electronics unit (12) is disposed in the tool body (2). A voltage supply contact (14) that is electrically insulated relative to the tool body (2) is is disposed on the attachment extension (5), which contact is connected with a voltage supply module (15) of the electronics unit (12). Furthermore, a change-over switch (16) is disposed in the connection line (10), wherein in a first switching position, the tool identification marker (11) is connected with the communication interface (9), and in a second switching position of the change-over switch (16), the electronics unit (12) is connected with the communication interface (9).

A tray bender allows a user to easily and efficiently bend a tubing tray or similar item. The tray bender includes a shaft and a tray-bending head. The shaft is an elongated, tubular structure which acts as a gripping element of the tray bender. The tray-bending head is a specifically designed structure which is used to engage the tray bender with a tubing tray or similar item. The user can apply an input force onto the end of the shaft opposite to the tray-bending head in order to provide a torque force to bend a tubing tray or similar. The tray-bending head is designed with prong-like structures with a gap space in between each prong-like structure to receive a tubing tray or similar item.

The invention relates to a bending machine (10) for bending a workpiece (12) out of a flat material, such as a sheet for example. A section (14) to be bent may be reshaped relative to a clamped section (16) of the workpiece (12) about at least one bending axis (18), wherein the bending machine (10) comprises: a machine frame (20); a first side clamping wall (22); a second side clamping wall (24) which can be moved relative to the first side clamping wall (22); and at least one bending unit (26, 28) comprising at least one bending tool (30). The first side clamping wall (22) and the second side clamping wall (24) are designed to clamp the workpiece (12) on a clamping plane (32). Furthermore, the bending unit (26, 28) is arranged on at least one of the first and second side clamping walls (22, 24) and is designed to bend the workpiece (12) section (14) to be bent relative to the clamped workpiece (12) section (16) about the at least one bending axis (18). According to the invention, the bending unit (26) has at least one linear guide (34-46), by means of which the bending tool (30) is linearly guided in order to be moved on an advancement plane (48).

A press brake includes paired fixation links, upper link arm, lower link arm and paired raised-lowered links, which form a parallel link mechanism configured to allow an operation panel to be raised and lowered. The press brake includes a spring configured to generate torque depending on a height position of the operation panel in an opposite direction to torque generated by weight of the operation panel; and a torque hinge configured to maintain a posture of the parallel link mechanism by absorbing a torque difference between the torque generated by the weight of the operation panel and the torque generated by the spring.

The invention relates to a method, use or a profile for manufacturing metallic flat materials to a cost-effective load-bearing structure of a passenger car and the usage of it. As the main forming manufacturing method the bend forming according to DIN EN ISO 8580 is used.
