The movement in the vertical direction of the pawls (18) is produced by means of individual motors (46), equipped with a shaft (48) which protrudes from their lower face and engages to the upper end of said nut screw (36).

A blocking device of tool-holders on lathes, especially for the rapid and precise blocking of tool-holders on CNC (Computer Numerical Control), single spindle or multi-spindle lathes as well as on transfer machines, milling centres of any kind and, in general, on machine tools which perform machining by chip removal, is paired with a tool-holder, motorized or non-motorized, connected to the existing support on said lathes and comprises an anchoring pawl provided with a female truncated-cone shaped recess. Said pawl is moved vertically with respect to the longitudinal axis of said tool-holder by mechanical or hydraulic means driven to engage said female, truncated-cone shaped recess with an inclined, male truncated-cone appendage made on said tool-holder.

The invention relates to a bending tool storage device (1) for storing bending tools (2), comprising at least one storage unit (3), which comprises an outer tool storage (4) which is ring-shaped or partial-ring-shaped and has a plurality of guide rails (14) for holding and guiding bending tools (2), characterized in that the storage unit (3) comprises at least one inner tool storage (5, 6) which is arranged inside the outer tool storage (4) and has a plurality of guide rails (15, 16) for holding and guiding bending tools (2), and in that the outer tool storage (4) and the inner tool storage (5, 6) are rotatable relative to one another, wherein, in different positions of relative rotation between outer tool storage (4) and inner tool storage (5), at least one guide rail (14) of the outer tool storage (4) is in each case in aligned orientation with another guide rail (15, 16) of the inner tool storage (5, 6).

A chuck device capable of efficiently changing a welding tip and nozzle. The chuck device includes a rotatable chuck base, an engagement part fixed to the chuck base so as to rotate integrally with the chuck base and can engage an engagement surface of the welding tip, the engagement part allowing the welding tip to rotate with the chuck base when the chuck base is rotated while engaged with the engagement surface, and a plurality of fingers provided to the chuck base to be openable and closable and can hold the welding tip and the nozzle, the plurality of fingers being capable of moving in directions approaching and separating from the engagement part.

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.

The present invention relates to a machine tool including a ram spindle and a tool holder, and provides a machine tool comprising: a tool holder including at least two inserts; and a ram spindle capable of fixing the tool holder in a clamped state or rotating the tool holder in order to change the position of the insert, such that the position of the insert can be quickly changed, thereby enabling an improvement in productivity and precision and a reduction in product costs.

A machine tool for processing plate-like workpieces, in particular metal sheets, has a machine frame with a lower frame arm, an upper frame arm and a frame compartment or throat defined between the upper and lower arms. A first tool magazine, close to the station, has storage places for processing tools is arranged at least partially within the frame compartment. The processing tools, such as punch/die sets, can be interchanged at a processing station of the machine tool. By means of a tool transfer device, processing tools can be transferred between the first tool and a second tool magazine, remote from the station. The second tool magazine has a magazine platform that protrudes laterally in a horizontal direction with respect to the machine frame and is accessible from above, on which magazine platform storage places for processing tools interchangeable at the processing station are provided, and above which a tool holder of the tool transfer device is mounted on the relevant longitudinal side of the machine frame.

System for handling dies with a rectangular and/or arched transverse cross-section that comprises a support for placing in a removable manner dies having a rectangular transverse cross-section, the support being designed to be coupled in a sliding manner to a fixed structure, in which at least said support has fastening means for holding at least one die with a rectangular transverse cross-section vertically in the air; and a handler provided with hooking means designed to be coupled to the support to place and/or remove the support with respect to the fixed structure, the handler having coupling means to be coupled to a transelevator or similar. This system is designed to facilitate the operations of placing and removing the dies during their storage.
