The punching tool 10a for punching and / or for perforating at least one molding element from a workpiece comprises at least one main body unit 12a, at least one punch cutting unit 14a, which comprises at least one blade element 16a, which can be arranged on the main body unit 12a, and at least one positioning unit 18a positioning of the blade element 16a relative to the base body unit 12a. The basic body unit 12a is hereby designed as a frame unit which limits a blade element arrangement space within which the blade element 16a can be variably arranged in a single position. In this case, the basic body unit 12a comprises at least one longitudinal frame element 30a and one transverse frame element 32a, which are connected to one another in a form-locking and / or force-locking manner. Here, the longitudinal frame member 30a and the transverse frame member 32a are releasably fixed to each other, such as by means of a screw etc. However, it is also conceivable that the longitudinal frame member 30a and the transverse frame member 32a are materially interconnected. The longitudinal frame member 30a and the transverse frame member 32a are aligned in a mutually fixed state orthogonal relative to each other. However, it is also conceivable that the longitudinal frame member 30a and the transverse frame member 32a include a deviating from 90 ° angle in a mutually fixed state. Overall, the basic body unit 12a has at least two longitudinal frame elements 30a, 34a and at least two transverse frame elements 32a, 36a which are connected to one another in a form-locking and / or non-positive manner. In a mutually fixed state of the longitudinal frame members 30a, 34a and the transverse frame members 32a, 36a, the base body unit 12a has a polygonal, in particular a cuboid, shape. It is also conceivable the basic body unit 12a comprises one of two different numbers of longitudinal frame elements 30a, 34a and / or transverse frame elements 32a, 36a. As a result, an adjustability of a frame size of the basic body unit 12a is possible. Depending on a desired frame size and a desired shape of the basic body unit 12a, correspondingly long transverse frame elements 32a, 36a could thus be connected to correspondingly long longitudinal frame elements 30a, 34a. However, it is also conceivable that the longitudinal frame members 30a, 34a and / or the transverse frame members 32a, 36a are variably adjustable in length, such as by means of a telescopic rod-like configuration, etc.

Furthermore, at least the longitudinal frame elements 30a, 34a each comprise at least one receiving element 38a, 40a for connection to at least one guide element 22a of the positioning unit 18a. Overall, the longitudinal frame members 30a, 34a each have a plurality of receiving elements 38a, 40a, which are provided for connection to at least one guide element 22a of the positioning unit 18a. The guide element 22a is formed here as a guide rod. Thus, the guide element 22a forms a transverse guide rod on which the at least one blade element 16a can be arranged. However, it is also conceivable that the guide element 22a another, one skilled in the expediency appear appropriate configuration, such as a configuration as a guide rail, etc. The receiving elements 38a, 40a of the longitudinal frame members 30a, 34a are each formed as a recess in which the guide element 22a can be arranged. However, it is also conceivable for the receiving elements 38a, 40a of the respective longitudinal frame elements 30a, 34a to have another configuration which appears expedient to a person skilled in the art, such as a design as a dovetail element, etc. The receiving elements 38a, 40a of the longitudinal frame elements 30a, 34a are considered along a total longitudinal extension of the respective longitudinal frame member 30a, 34a, evenly distributed on the respective longitudinal frame member 30a, 34a arranged. However, it is also conceivable for the receiving elements 38a, 40a of the longitudinal frame elements 30a, 34a to be distributed unevenly along the entire longitudinal extension of the respective longitudinal frame element 30a, 34a on the respective longitudinal frame element 30a, 34a. So that's it Guide element 22a positionally adjustable on the basic body unit 12a, in particular on the longitudinal frame members 30a, 34a, can be arranged.

In addition, the transverse frame elements 32a, 36a also each comprise at least one receiving element 42a, 44a for connection to at least one further guide element 46a of the positioning unit 18a. Overall, the transverse frame elements 32a, 36a each have a plurality of receiving elements 42a, 44a, which are provided for connection to at least the further guide element 46a of the positioning unit 18a. The further guide element 46a is formed here as a guide rod. Thus, the further guide element 46a forms a longitudinal guide rod on which the at least one blade element 16a can be arranged. However, it is also conceivable that the further guide element 46a another, a person skilled in the appear appropriate design, such as a configuration as a guide rail, etc. The receiving elements 42a, 44a of the transverse frame members 32a, 36a are each formed as a recess in which the other Guide element 46a can be arranged. However, it is also conceivable for the receiving elements 42a, 44a of the respective transverse frame elements 32a, 36a to have another configuration which appears expedient to a person skilled in the art, such as a design as a dovetail element etc. The receiving elements 42a, 44a of the transverse frame elements 32a, 36a are considered along a total longitudinal extension of the respective transverse frame element 32a, 36a, evenly distributed on the respective transverse frame element 32a, 36a arranged. However, it is also conceivable for the receiving elements 42a, 44a of the transverse frame elements 32a, 36a to be distributed unevenly along the overall longitudinal extent of the respective transverse frame element 32a, 36a on the respective transverse frame element 32a, 36a.

Thus, the further guide element 46a positionally adjustable on the main body unit 12a, in particular on the transverse frame elements 32a, 36a, can be arranged. In a state of the guide element 22a arranged on the longitudinal frame elements 30a, 34a and in a state of the further guide element 46a arranged on the transverse frame elements 32a, 36a, the latter run Guide element 22a and the further guide element 46a at least substantially transversely to each other. The guide element 22a and the further guide element 46a thus form strut elements for stabilizing the basic body unit 12a designed as a frame unit. Thus, advantageously, a high torsional rigidity of the basic body unit 12a can be achieved. The positioning unit 18a has a plurality of guide elements 22a and further guide elements 46a, which can be variably arranged in position on the main body unit 12a. Furthermore, the guide element 22a comprises at least one feedthrough recess 60a, through which the further guide element 46a can be passed. Overall, the guide element 22a has a multiplicity of feed-through recesses 60a which are arranged distributed uniformly along the guide element 22a along a total longitudinal extent of the guide element 22a. Thus, depending on an arrangement of the feedthrough recesses 60a, the further guide element 46a can be arranged in stages in different positions relative to the guide element 22a on the guide element 22a.

The at least one blade element 16a can be arranged on the guide element 22a or on the further guide element 46a. In this case, the at least one blade element 16a can be arranged movably on the guide element 22a or on the further guide element 46a. The at least one blade element 16a is mounted to be translationally movable in a state arranged on the guide element 22a or on the further guide element 46a, at least in one state, in particular in an unfixed state on the guide element 22a or on the further guide element 46a. In addition, the at least one blade element 16a can be arranged in an individually detachable manner on the main body unit 12a. In this case, the blade element 16a can be arranged detachably on the main body unit 12a independently of at least one further blade element 24a of the punch cutting unit 14a. Thus, the at least one blade element 16a can be arranged in a single-position variable manner on the main body unit 12a by means of the positioning unit 18a. The at least one further blade element 24a can also be arranged in a single-position variable manner on the main body unit 12a by means of the positioning unit 18a. Thus, the punch cutting unit 14a comprises the at least one further blade element 24a, which by means of the positioning unit 18a Independently of the at least one blade element 16a, it can be arranged in a single-position variable manner on the main body unit 12a ( FIGS. 3 and 4 ).

The blade bearing element 48a is in particular intended to support forces which act on the at least one blade element 16a during machining of a workpiece. Thus, the blade support member 48a is provided for stabilizing and / or stiffening the at least one blade member 16a. The blade support element 48a comprises at least one connection region 50a for arranging the at least one blade element 16a. The connection region 50a is provided to receive the guide element 22a or the further guide element 46a in a state of the at least one blade element 16a arranged on the base body unit 12a by means of the positioning unit 18a. For this purpose, the connecting portion 50a is formed as recesses. The connection area 50a has an oval configuration. Another embodiment of the connection region 50a which appears expedient to a person skilled in the art is likewise conceivable, such as an elliptical design, a polygonal design etc. However, it is also conceivable that the punch cutting unit 14a is decoupled from the blade support element 48a and the connection region 50a is formed directly in which at least one blade element 16a is inserted. Overall, however, the punch cutting unit 14a has at least two blade bearing elements 48a, 52a, between which the at least one blade element 16a is arranged. Furthermore, in addition to the blade bearing elements 48a, 52a, the punch cutting unit 14a comprises at least one hold-down element 54a (in FIG FIG. 4 shown in dashed lines), which is provided for holding down the workpiece during a machining operation or for stripping a stamped out of the workpiece molding element.

At least one hold-down element 54a, 82a is preferably arranged on each of the blade bearing elements 48a, 52a. The hold-down member 54a is formed of an elastic material such as foam, rubber and so on.

Furthermore, the positioning unit 18a comprises at least one fixing element 20a at least for securing the at least one blade element 16a in at least one position relative to the main body unit 12a. The fixing element 20a is positionally adjustable on the positioning unit 18a can be arranged. In this case, the fixing element 20a can be arranged at least on the guide element 22a. The fixing element 20a is designed as a clamping element. The fixing element 20a has an arrangement region which is formed corresponding to an outer contour of the guide element 22a. However, it is also conceivable that the fixing element 20a has another, to a person skilled in the expedient design, such as a configuration as a latching element, which cooperates with grids of the guide element 22a, etc. The fixing element 20a is by means of a clamping element 56a of the positioning unit 18a in an arbitrary position, in particular in any position with respect to a total longitudinal extension of the guide element 22a, on the guide element 22a can be arranged. The clamping element 56a is formed here as a screw. However, it is also conceivable that the clamping element 56a another, a skilled person appears appropriate design, such as a design as toggle element, etc. As a result of a transfer of the clamping element 56a in a clamping position, the fixing element 20a by means of an interaction with at least one Gegenfixierungselement 58a the positioning unit 18a clamped to the guide member 22a. The counter-fixing element 58a can be arranged movably on the fixing element 20a by means of a joint. A separate embodiment of the fixing element 20a and the Gegenfixierungselements 58a are also conceivable. In addition, it is also conceivable that the fixing element 20a is formed integrally with the blade bearing element 52a or with the at least one blade element 16a itself. Overall, the positioning unit 18a has a multiplicity of fixing elements 20a, which are provided to secure the at least one blade element 16a in at least one position relative to the main body unit 12a on the guide element 22a. In this case, the at least one blade element 16a is clamped between at least two fixing elements 20a arranged on the guide element 22a ( FIG. 4 ). In an arrangement of the at least one further blade element 24a on the guide element 22a, this is at least one more Blade element 24a fixable by means of the fixing elements 20a on the guide member 22a. The at least one further blade element 24a is arranged to be arranged on the positioning unit 18a and / or on the main body unit 12a analogously to the at least one blade element 16a between two blade bearing elements (FIG.
