  • the article also has elements which, controlled by the levers, press the pipes to be pressed.
  • 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.
  • 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.
  • 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.
  • a preferably hydraulically actuated device connectable, for example, as a pair of jaw pair trained baking pair for punching holes in sheet metal parts known, wherein on a jaw a punch and on the other jaw a punch opening is formed.
  • a preferably hydraulically actuated device connectable, for example, as a pair of jaw pair trained baking pair for punching holes in sheet metal parts known, wherein on a jaw a punch and on the other jaw a punch opening is formed.
  • an embodiment is provided with swivel jaws, wherein the relative movement of the swivel jaws, however, is not a linear movement, but a rotational movement about an axis of rotation.
  • an embodiment with sliding jaws is provided, which are not rotatably mounted.
  • the aim of the present invention is therefore to avoid this disadvantage and to provide an attachment for pressing devices, with which passage openings in workpieces, preferably in profile components or metal standings can be made easily and quickly and precisely. Furthermore, the stability of the uprights should not be impaired and there should be no sharp corners or edges, so that persons can not be injured and the fürzufädelnden lines can not be damaged.
  • an attachment for a manually or motor driven, durable in the hand pressing device wherein the attachment comprises a base body and two rotatably mounted thereon, which of the Pressing device can be actuated, achieved in that the attachment comprises a die and a punch, which are arranged along an actuating axis against each other movable, and the levers are provided to drive the die and the punch, wherein the punch is a cutting edge and the die an abutment for cutting through openings in profile components, preferably metal uprights.
  • the passage opening can be generated quickly and easily with the aid of the attachment according to the invention, whereby the stability of the metal posts is not impaired.
  • the through hole has no sharp edges or corners where people can injure themselves or the cables to be laid can be damaged.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 ,
  • 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.
  • first and second carriers are each guided in a guide element arranged on the attachment.
  • This guide element can be designed to be elongate along the actuating axis and have a recess corresponding to the recess of the respective lever.
  • the first and second supports are each elongated, preferably cylindrical, wherein the longitudinal axes of the first and second support are each identical to the actuation axis.
  • the respective lever guides the first and second elongated support along the actuation axis.
  • the die is arranged in an end region of the first and the punch facing the die in an end region of the second support facing the die.
  • the die or the punch is arranged centrally on the respective carrier.
  • the punch has a side wall enclosing the actuating axis with at least one edge facing the die, wherein the edge facing at least one of the die is designed as a cutting edge.
  • the shape of the edge may have corners or be round, the shape defines the shape of the through holes to be cut in the profile components.
  • the shape of the through holes can be made different. Because the edge is designed as a cutting edge, an easily manufactured and stable cutting edge is available.
  • the die has a receiving space for receiving at least one cut-out part of the profile components, preferably metal posts.
  • This receiving space is open on the side facing the stamp and serves to receive both the cut-out part of the profile components, as well as a part of the punch at the end of the cut. Therefore, according to a further embodiment variant of the attachment according to the invention, provision is made for the side wall of the stamp to project into the receiving space at least in sections in an end position in which the cutting edge has cut through the passage opening. Die and punch are thus cup-shaped and pushed into one another.
  • the die has a side wall enclosing the actuating axis, which limits the receiving space normally to the actuating axis, wherein the side wall has an end face facing the punch, which forms the abutment of the die.
  • the face of the sidewall is that part of the sidewall of the die which is closest to the die and faces. This end face of the side wall is applied to the profile components at the point to be cut and provides the abutment for the punch during the cut.
  • an inner surface of the side wall of the die is aligned parallel to the actuating axis.
  • the cutting edge of the stamp has a closed circumference about the actuation axis.
  • the cut-out part of the profile component can be completely removed. If the cutting edge of the punch is not closed around the actuating axis, the point where the cut was made must first be bent to the side in order to release the through hole.
  • all points of the cutting edge have the same distance to the inner surface of the side wall of the die, whereby the sheath has the same course as the side wall of the die and the distance can be preferably kept so low that the Profile components are kept stable during the cut.
  • the side wall of the die is rotationally symmetrical with respect to the actuating axis, which represents a particularly simple and cost-effective variant.
  • the side wall of the punch is formed in relation to the actuating axis is substantially rotationally symmetrical.
  • the matrix is detachably arranged on the first and the punch is detachably arranged on the second support.
  • the stamp on the first and the die on the second carrier are each arranged screwed.
  • the advantage is that different matrices and stamps can be used (for example with different diameters).
  • the thread also serves to be able to quickly and easily unscrew a die or a stamp on the support or to be able to remove, so that different matrices, for example, for different hole sizes can be easily changed.
  • the cutting edge of the punch is rotationally symmetrical with respect to the actuation axis is trained. This is a particularly easy to manufacture variant and the cut also creates no sharp edge.
  • the side wall of the punch has an outer surface which is tapered running to the actuating axis, wherein the distance of the outer surface decreases to the actuating axis with increasing distance to the die. It is understood by conical that an outer circumference of the rotationally symmetrical side wall, which is closer to the die, is greater than a farther removed. The circumference decreases with increasing distance to the matrix. If the front part of the punch, which comprises the cutting edge, penetrates into the receiving space of the die after cutting, then, as the punch is withdrawn, it does not become so easily wedged in the cut workpiece due to the conical outer shape of its side wall.
  • one of the two supports has a guide extension which, upon actuation of the attachment between an actuation position, in which die and punches intersect the profile components, and reaches the end position in a guide opening of the other support provided for this purpose is.
  • This guide extension is arranged centrally on the actuating axis, running elongated and thus displaceable with its longitudinal axis along the actuating axis.
  • the guide extension protrudes into the spaced space between the die and punch in an initial position in which the levers have not yet been actuated by the pressing device and can be introduced into a predrilled hole in the profile component.
  • the guide extension Before the punch contacts the profile component, the guide extension can already be pressed into the guide opening upon actuation be introduced. Thus, the stamp is given a guide and thus a lateral support at the time of the cut. It is conceivable to arrange the guide extension detachable.
  • a spring connecting these is attached to the two rotatably mounted levers, which exerts a pressure on the two levers in the end position, to be able to return the two rotatably mounted lever from the end position to a starting position in which the die and the stamp are spaced from each other.
  • the nature of the spring is not critical, it can therefore be performed as a simple, slightly curved metal rod, which is inexpensive to manufacture the spring.
  • a stop ring enclosing it at least partially is arranged, which is present in the actuation position on the side facing the punch of the side wall of the die to the punch from the receiving space of the die to be able to push out or to push the stamp away from the die.
  • the stop ring is arranged in a direction corresponding to the actuating axis displaceable on the outer surface of the side wall of the punch.
  • At least one Abdrückfeder is arranged on the punch, which connects the stop ring and the punch together and exerts a pressure in the direction corresponding to the actuating axis on punch and stop ring to move the stop ring in the direction of the die ,
  • the outer surface of the side wall of the punch has a stop edge and the stop ring has a stop lip associated with the stop edge in order to limit the movement of the stop ring in the direction of the die.
  • the die has a region which rises at the bottom of the receiving space and rises in the direction of the punch, which partially bridges the receiving space in the direction corresponding to the actuating axis and which in the end position is in contact with the side wall of the punch partially overlapped with respect to the actuation axis in order to bend the part of the profile component cut off by the cutting edge, preferably metal posts.
  • This area can be designed as a rotationally symmetrical wall about the actuation axis or as a central elevation. The cut part can be more easily removed from the receiving space as a result of its bending after the cut.
