STATE OF THE ART

Manual or motor driven, hand-held pressing devices are used with attachments. Different attachments can be used. In the construction of houses or in the renovation of flats and houses, attachments are used for said pressing devices with which one can press fittings (pipes) together. A pressing device with a fitting for pressing fittings is also referred to as a fitting press machine or Fittingpresszange. Since they are used in house construction, they represent a standard tool for installers, for example. Fitting press machine and Fittingpresszange each consist, as mentioned, of a pressing device and a top, wherein the pressing device actuates the attachment. In the case of the fitting press machine, this is motor-driven and driven manually in the case of the Fittingpresszange. The principle is the same in both cases, the pressing device operated, motorized or manually, two levers of the essay, which are rotatably mounted on a base body of the essay are. The article also has elements which, controlled by the levers, press the pipes to be pressed.

For walls, in particular plasterboard walls, an elevation is often used. In this case, U-shaped metal posts between the floor and ceiling are often mounted in cross-section and wall plates, such as plasterboard, attached, which form the wall in a row.

To be able to lay all kinds of lines in the walls, it is necessary to create through holes in the uprights. This often happens inelegant and expensive with the help of a flex.

This type of production of through holes not only has the disadvantage of being expensive, but also affects the stayer in terms of their stability. With the Flex, the cuts are often set uncontrollably and thereby too long cuts are produced, which affect the stability of the stayer.

Another disadvantage is that the through holes often have sharp corners or edges at which people injure themselves or the durchzufädelnden lines can be damaged. Due to the sparking there is also a risk of fire.

From the WO 2004/078398 A1 is a pressing device for pressing of coupling elements with a fork-shaped receptacle and with a held in this recording by means of a connecting bolt interchangeable tool known, which has two mutually movable pivot arms. At each pivot arm a scissor plate is basically attached, which may be formed as a male and female, the can be moved towards each other via the pivot arms to punch slots in profiles.

In addition, the through hole has no sharp edges or corners where people can injure themselves or the cables to be laid can be damaged.

Since the attachment according to the invention is suitable for all standard pressing devices, in particular also for pressing devices of fitting press machines, it is particularly easy to use the fitting pressing machine for cutting through openings in profile components, preferably metal posts, only the attachment needs to be exchanged.

The die and the stamp are actuated by the levers in that they are moved towards each other by the levers and the pressure necessary for the cut is built up. The receiving space serves to receive the separated part of the post, which falls out of the receiving space after the divergence of die and punch or can be easily removed. The cutting edge is in the final position near the inner surface of the side wall comprising the receiving space, whereby the part of the post to be separated can be efficiently cut.

In order to ensure a stable and simple guidance of the die and the punch, it is provided in a preferred embodiment of the attachment according to the invention that the die are arranged on a first and the punch on a second each movably mounted on the attachment carrier. The carriers may be square or cylindrical and their attachment to the die or stamp is preferably carried out interchangeably. It is understood by movably mounted, that the two carriers are attached to the body of the essay so that they can still move along the actuation axis against each other. Mounted may mean that the carriers are arranged displaceably at least in sections along the actuation axis in guide elements, or that they are movably arranged by means of bearings. Furthermore, it is provided that first and second carriers are each moved by one of the two levers in order to move the carriers towards and away from one another along the actuation axis. Actuation of the die and punch by the levers via the carrier is a particularly simple possibility. This gives the carriers the task of ensuring the correct guidance. What is attached to each of the two supports is variable and can also be subsequently changed.

According to a further embodiment variant of the attachment according to the invention, it is provided that first and second carriers are each provided with a recess into which in each case a first end region of one of the two levers engages in order to move the carriers towards and away from one another along the actuation axis. This recess can be designed as a slot, in which the matching end portion of the lever is introduced. In this case, in the recess, a contact surface, which represents the contact between the lever and the carrier, bent around an orthogonal to the actuating axis standing axis, and the associated part of the lever to be straight, or vice versa, which is a good power transmission. The lever can thus guide the movement of the wearer in the direction of the other wearer or even away from it.

According to a further embodiment variant of the attachment according to the invention, it is provided that the levers of the pressing device can each be actuated in a second end region, wherein the second end region is arranged on a side of the levers opposite the first end region with respect to a rotatable mounting of each lever , Ideally, the contact surface at which the pressing device contacts the respective lever is bent or executed in the form of a curve. The shape of the bend defines the translation or the speed of rotation of the lever. This makes it possible to optimally transfer the force of the pressing device to the carrier and thus also subsequently to the die and the punch.

In order to be able to control the movement of the two carriers most optimally, it is provided in a further embodiment variant of the attachment according to the invention that first and second carriers are each guided in a guide element arranged on the attachment.
