In an installing method for installing divided upper tools to upper tool holders disposed to be spaced at an appropriate interval in a left-right direction in a lower portion of an upper table of a press brake, by using a tool changer, a round bar-shaped finger provided in the tool changer is engaged in a circular engagement hole provided at a central portion in the lateral direction of each divided upper tool. The divided upper tool is temporarily positioned in a gap between an upper tool holder to which the divided upper tool is to be installed, and an adjacent upper tool holder. The temporarily positioned divided upper tool is moved in the left-right direction to be installed to the upper tool holder to which the divided upper tool is to be installed.

A sheet material bending system includes a tool changing apparatus that changes tools between a press brake and a tool stocker. The tool stocker is arranged behind the press brake. To change tools from the front and rear of the tool stocker, the front and rear of the tool stocker are opened. The tool changing apparatus has a pivot that is movable in front-rear, left-right, and up-down directions and is rotatable around an axis extending in the up-down direction. A front end of the pivot is provided with tool holding units to hold tools.

The invention relates to a tool magazine (1) for a manipulator (4) comprising a plurality of tool holding fixtures (2) which are distributed in a preparation area (7), especially in a substantially vertical preparation plane (11). The tool magazine (1), on one side (9) of the preparation area (7), comprises a first access opening (10) facing the manipulator (4) and, on the other side (15) of the preparation area (7), a second access opening (16) facing an operator (13) and the first access opening (10) is associated with a first protective device (17) and the second access opening (16) is associated with a second protective device (18).

The invention relates to a spot welding cap changer (1) with a cap puller (2) and two cap magazines (3, 3A), the cap puller (2) having a gripper (20) with spring-loaded, pivotable jaws (21, 22), which in response to a turning and axial pulling-off movement detaches a spot welding cap (K) of a pincer spot welding head introduced into it from a shaft of the pincer welding head in such a way that it is clamped to prevent it twisting, and the cap magazines (3, 3A) holding spot welding caps respectively in a round cap carrier (31) such that they are circularly arranged in a directed and oriented manner and are respectively transported individually one after the other into an access position against a stop (32) by an advancing force (P).

A container treatment system (1, 13) that has at least two working areas (AP). Each of the working areas (AP) respectively comprises at least one exchangeable working tool (2) and/or one adaptable format part. Furthermore, the container treatment system (1, 13) comprises at least one automatic exchange machine (10) which is movable, in particular drivable, to the at least two working areas (AP), which automatic exchange machine (10) can be connected selectively to any of the respective working areas (AP), in particular using centering means (22, 32), and which automatic exchange machine (10) comprises tools for exchanging the working tools (2) and/or for adapting the format parts of the respective working area (AP). The invention further relates to an automatic exchange machine (10) for exchanging working tools (2) and/or for adapting the format parts of at least two different working areas (AP) of a container treatment system (1, 13).

A machine tool can perform a turning process using a fixed tool and a milling process using a rotating tool. The machine tool includes: a tool spindle having an air supply portion, for rotating the rotating tool; a lower tool rest for mounting a plurality of fixed tools thereon; a tool holder having a tapered surface restraining a tool, and attached to the lower tool rest, for detachably holding the tool; an automatic tool changer; and a special tool mounted on the tool spindle, into which the air is introduced from the air supply portion. When the tool is automatically changed by the automatic tool changer, the special tool mounted on the tool spindle is coupled to the tool holder, and the air from the air supply portion is supplied to the tapered surface through the special tool.

An electro-hydraulic joint supplying system for electrical machining and supporting automatic tool changing includes an electro-hydraulic joint supplying device and a clamping device. The electro-hydraulic joint supplying device includes an insulator, an electro-hydraulic joint supplying base, an electro-hydraulic joint supplying pipe terminal, and an electro-hydraulic joint supplying pipe. The base is fixedly connected with a spindle shell through the insulator. A working fluid pipe connector and a wiring post are arranged on the base; a terminal connector is in a snap-fit with a top end of the electro-hydraulic joint supplying pipe terminal. The pipe terminal communicates with a flushing fluid container in an electrical machining electrode shank through an electro-hydraulic joint supplying pipe. The clamping device includes a first clamping mechanism, a second clamping mechanism, and a cooperation mechanism fixedly connected with the first clamping mechanism or the second clamping mechanism to circumferentially limit the flushing fluid container.
