The disclosure relates to a tool storage device for a machine tool having a tool storage unit which can be mounted and displaced on a guide rail of the machine tool and is further designed to receive non-mounted tools for the machine tool.

A radial press has a plurality of press bodies arranged around a press axis which can be moved radially in relation to the press axis, and a drive unit for shifting the press bodies in the direction of or away from the press axis. The press bodies each have a main jaw and a pressing jaw, which is fixed interchangeably on the main jaw. The main jaws each comprise a radially inwardly arranged pressing-jaw-supporting surface and, adjacent to the latter in the circumferential direction, two side surfaces. The pressing jaws butt against the pressing-jaw-supporting surface of the associated main jaw and have a fixing protrusion, which projects from the abutment surface, enters into a mount provided on the main jaw and interacts with a locking device. Each main jaw has a recess on its supporting surface which extends from the mount and opens out on one of the side surfaces.

An automatic tool changer includes first and second tool change units that is driven respectively by a pair of servo motors and move along an arrangement direction of a plurality of tools installed on a tool installation unit, a torque detection unit that detects a torque of each of the pair of servo motors, and a control device that controls operations of the first and second tool change units. The control device fixes the first tool change unit at a reference position, and moves the second tool change unit toward the first tool change unit. The control device determines, based on a torque change of each servo motor, that a plurality of upper tools are brought together at the first tool change unit as a result of a movement of the second tool change unit.

The invention relates to a bending press (1) and/or a loading device (2) for loading a bending press (1) with bending tools (5, 6), comprising: at least one tool holder (3, 4; 13, 14) with a rail (7) having an inner profile (8) for receiving and displacing a bending tool (5, 6), at least one internal wall (9) of the rail (7) forming a guide structure (10) extending in the longitudinal direction of the rail (7); and at least one transfer device (15) drivable by a drive (21) for displacing a bending tool (5, 6) within the tool holder (3, 4; 13, 14) and/or between the tool holder (13, 14) of the loading device (2) and a tool holder (3, 4) of a bending press (1), wherein at least one portion of the transfer device (15) is guided by the guide structure (10) formed in the rail (7).

A tool transfer device for displacing one or multiple tools, in particular bending tools, in a guide rail, includes: at least one longitudinal push and pull transfer device for displacing the tool(s), a channel for a supply line being formed in or on the push and pull transfer device, a receptacle including at least one, preferably spirally extending, guide for retracting the push and pull transfer device, and at least one supply line, a first section of the supply line extending in the push and pull transfer device channel. The guide includes a longitudinal opening extending along the guide extension, and a second supply line section extends outside the push and pull transfer device and the receptacle guide, and the supply line, between the first and second sections, exits the channel at an exit point arranged in the guide of the receptacle near the push and pull transfer device.

The invention relates to a bending press (11) for bending metal sheets, comprising a top beam (21) and a lower beam (26), and two drawers (31, 31A). Said drawers (31, 31A) are arranged at both sides of the lower beam (26) and are designed to accommodate bending tools and/or parts.

A tool storage device is disposed on a side of a press brake. In the tool storage device, a lower tool holder is lifted up from lower tool holder support members, is moved forward or backward, and both end sides in a left-and-right direction of the lower tool holder are lowered after being passed through recessed portions formed on the lower tool holder support members (step (a)). The lowered lower tool holder is conveyed forward, and is positioned to a same height as a height of a lower tool mounting portion in a lower table (step (b)). The lower tool held in the lower tool holder is transferred to the lower tool mounting portion by a tool replacement device, and is mounted on the lower table (step (c)). The lower tool mounted on the lower table is returned into the tool storage device (step (d)).

The invention relates to a device for changing bending tools (15, 16) in a bending machine (2) for bending metal sheets, in particular in a press brake, comprising at least one tool magazine (6) for storing the bending tools (15, 16), which, when positioned in a working area of the bending machine (2), cause the metal sheets to bend. The at least one tool magazine (6) is arranged on a frame (3) which is configured to be positioned in a free-standing manner without a mechanical connection to the bending machine (2) in an operating position of the device (1), wherein the at least one tool magazine (6) can be moved from a first position out of the frame (3) into a second position, in which at least a part of the tool magazine (6) that can be moved out lies in a contact-free manner within the bending machine (2).

A rotatable buffer turret apparatus on which plural pairs of punches and dies to be set on a turret of a turret punch press are set, includes an upper buffer turret on which punch attachment holes in which the punches can be set are arranged circularly, and a lower buffer turret on which die attachment holes that is associated with the punch attachment holes and in which the dies can be set are arranged circularly. The upper and lower buffer turrets are rotatably attached to a single rotary shaft. A diameter of the lower buffer turret is made larger than a diameter of the upper buffer turret. The die attachment holes are formed in a circular die attachment area having a diameter larger than the diameter of the upper buffer turret. According to the apparatus, a tool exchange manually operated by an operator can be done easily and efficiently.

On a back side of a table, moving bodies are provided being movable in a left-right direction. A bending system includes moving actuators to cause the moving bodies to move in the left-right direction relative to the table and position detectors to detect positions of the moving bodies in the left-right direction. The moving bodies are provided with hole detectors to detect the engagement holes tools fitted to a tool holder. The bending system includes a hole position acquisition unit to acquire positions of the engagement holes of the tools in the left-right direction, based on positions of the moving bodies in the left-right direction at the time of the engagement holes of the tools being detected.
