- the pressing tool holder 10 has a primary tool adjustment 20, which includes the X-direction adjustment 22 and the Y-direction adjustment 24.
- a rotational movement In order to be able to operate the X direction adjustment 22, a rotational movement must be carried out around the X actuation axis XB.
- a rotation around the Y actuation must be carried out.
- supply axis YB can be brought about.
- the X actuation axis XB and the Y actuation axis YB are oriented parallel to one another.
- the X direction adjustment 22 is based on two inclined planes spaced apart from one another in the Y direction.
- FIG. 3 shows a section through a pressing tool holder 10, the pressing tool holder 10 having a Y-direction adjustment 24, the Y-actuation 28 having to be actuated in order to actuate this Y-direction adjustment 24.
- An X-direction adjustment 22 is also provided in the pressing tool holder 10.
- the device shown also has a secondary adjustment 40 in the form of an L-actuation 44.
- FIG. 1 A perspective overall shot of a press machine tool 1 is shown in FIG.
- the pressing machine tool 1 which is designed as a multi-stage press, there are numerous pressing tool holders 10, which are arranged next to one another, in particular next to one another in the X direction or Y direction. Opposite each other are a pressing tool 100 in the form of a die and a pressing tool 100 in the form of a stamp.
- the pressing machine tool 1 has a robot system 300.
- the actuation unit 310 of the robot system 300 is stored in a magazine of the robot system 300 or the pressing machine tool 1. This magazine can be reached by an arm of the robot system 300 in order to be able to accommodate the actuation unit and thereby be able to operate the primary tool adjustment and/or the secondary tool adjustment.
- FIG. 5 shows a detailed view of a press machine tool 1, in particular the working space or the press space of the press machine tool is shown there.
- it has pressing tool holders 10 arranged next to one another, each of which has a pressing tool 100 in the form of a die and/or a stamp.
- FIG. 5 can belong to the embodiment of the pressing machine tool 1 shown in FIG. 4 and/or to the embodiment shown in FIG. 6.
- a gripping unit 320 is arranged on the arm of the robot system 300. By means of this gripping unit, the pressing tool 100 can be removed from the pressing tool holder 10 and/or inserted into it.
- the pressing tool holder 10 each has a primary tool adjustment, which in turn has an X actuation 26 for the X direction adjustment and a Y actuation 28 for the Y direction adjustment 24.
- some of the pressing tool holders 10, in particular all pressing tool holders and/or all pressing tool holders, which are arranged stationary in comparison to the foundation of the pressing machine tools have an L-actuation for a longitudinal direction adjustment 42, which can be part of the secondary adjustment 40 or can form the same.
- FIG. 6 also shows a detailed view of a pressing machine tool 1, wherein the robot system 300 has a gripping unit 320 and wherein the gripping unit 320 can be guided into a provision area in order to be able to pick up pressing tools 100 from a provision unit or place them in one or the provision unit to be able to.
- the or some of the provision unit(s) can be an exchangeable provision unit, in particular a provision unit located on a carriage and/or a cart.
- the pressing machine tool 1 has at least two parking spaces for one supply unit each. This makes it possible, in particular, to be able to introduce a completely new set of pressing tools into the pressing machine tool 1.
