Definitions

  • the present invention relates to a radial press, comprising a plurality of pressing bodies arranged around a pressing axis, movable radially to the pressing axis, and a drive unit for moving the pressing bodies in the direction of the pressing axis or away from it
  • the press bodies are constructed in several parts and each have a base jaw and an interchangeably fixed press jaw, the base jaws each have a radially inwardly arranged press jaw support surface and, adjacent to this in the circumferential direction, two side surfaces and the press jaws each have a counter surface on the press jaw Support surface of the associated base jaw and have a fixing projection protruding from the counter surface, which protrudes into a receptacle provided on the base jaw and interacts with a locking device arranged there.
  • the present invention relates to a radial press system, which comprises a radial press, a press jaw magazine storing interchangeable press jaws in sets and a quick-change device used for common press jaw change.
  • the fixing projections provided on the pressing jaws - for the exchangeable attachment of the pressing jaws to the base jaws - which protrude from the opposing surfaces of the pressing jaws, enter into the receptacle provided on the base jaws and interact with locking devices of the base jaws, are, for example, as radially outwardly from the pressing jaws protruding pins, tenons or bolts realized.
  • EP 2420332 A1 discloses a radial press according to the preamble of claim 1.
  • the pressing jaws are placed on the base jaws by radial movement of the respective pressing jaw relative to the relevant base jaw.
  • the press jaws can be placed individually by hand on the base jaws (from the radial inside).
  • the (simultaneous) radial movement of all base jaws and press jaws relative to one another is brought about by moving the base jaws radially inwards using the drive unit until the locking units engage.
  • the Dismantling of the press jaws for which purpose the locking devices are unlocked in a suitable manner.
  • the press jaws are pushed axially onto the base jaws for their assembly.
  • the base jaw-side receptacles for the fixing projections of the pressing jaws on the pressing jaw support surfaces of the base jaws extend in the axial direction like a groove up to the base jaw face from which the pressing jaws are assembled.
  • the press jaw set - typically comprising eight press jaws - can be handled as a whole for changing the press jaws, so that the complete press jaw set stored in a corresponding magazine is inserted into the radial press or removed from it and stored in the magazine.
  • This not only reduces the time required to convert a radial press, but also the risk of (incorrectly) equipping the radial press with press jaws of different types.
  • a quick-change tool with a handle and a press jaw holder that holds the press jaws - evenly arranged concentrically around the tool axis - is used.
  • the present invention has set itself the task of providing a radial press of the generic type which is further improved compared to the prior art, in particular with regard to flexibility, namely with regard to the possible pairings of base and pressing jaws.
  • the base jaws each extend on their pressing jaw support surface from the receptacle (for the fixing projection of the respective pressing jaw) to one of the side surfaces of the Have the base jaw extending, at this opening channel-like recess.
  • Such channel-like recesses which each extend from a side surface of the base jaw in question to its receptacle, allow that already during the assembly of the pressing jaws - taking place with a rotary movement of the pressing jaws around the pressing axis - their fixing projections at least at the end or partially in the - Defined by the respective pressing jaw support surface - protrude into the contour of the respectively assigned base jaw.
  • the relevant angle of rotation is preferably about half the division, ie in the case of a radial press having eight press bodies between about 20 ° and 25 °, for example about 22.5 °.
  • a particularly pronounced advantage of the invention is that, for mounting the press jaws, the respective distance between the press jaw support surfaces and the mating surfaces of the associated press jaws can be less than the amount by which the fixing projections on the respective mating surface protrude radially from the press jaws.
  • such press jaws can therefore also be mounted (together as a set) in a given radial press, which can at best be mounted individually in conventional radial presses of the generic type due to an insufficient distance between the base jaws when the radial press is opened to the maximum.
  • Another advantageous effect of the invention is that in comparison with the prior art, a more precise coordination of the fixing projections and the associated receptacles with one another - with regard to their dimensions - is possible, so that the prior art can be observed through corresponding play between Fixing projections and recordings caused axial offset of the press jaws to each other can be significantly reduced.
  • the recesses characteristic of the radial presses according to the invention extend, according to a first preferred development of the invention, exactly in the circumferential direction. This results in recesses of the shortest possible length, which results in only a minimal weakening of the base jaws, which also affects the less heavily loaded central area the base jaw is limited.
  • the press jaws are assembled using a strictly two-phase movement (first axial insertion, then rotation in the circumferential direction).
  • the fixing projections of the press jaws align with the free spaces between two adjacent base jaws.
  • the quick-change tool is effectively centered in such a way that its tool axis is aligned with the pressing axis.
  • the axial position of the quick-change tool with the press jaws accommodated, in which the second phase of the press jaw assembly, i.e. the rotary movement of the press jaws around the tool axis while moving the fixing projections in the recesses, is possible and can be carried out, can be achieved in particular by a stop (or several stops ) To be defined.
  • a stop or several stops
  • such a depth stop e.g. in the form of a disk
  • the disk in question can also act as protection against reaching into the pressing jaw installation space when changing the pressing jaws and thereby contributes significantly to the prevention of accidents.
  • the base jaws each have a recess extending from the opening of the recess to one of the end faces of the base jaw on that side surface at which the respective recess opens.
  • Such recesses provided on the edge in each case in the region of the transition from the pressing jaw support surface to the side surface of the base jaw in question, can in a sense serve as "feeders" for the fixing projections to the mouths of the recesses; they enable the set of press jaws to be inserted with fixing projections protruding into the contour defined by the pressing jaw support surfaces even if the (remaining) free spaces between two adjacent base jaws are too narrow to accommodate the respective fixing projections.
  • assembly or disassembly of the pressing jaws is even possible with the radial press completely or at least more or less closed, which can be advantageous for special applications with special pressing jaws.
  • the recesses explained above can also take on the function of a depth stop described above, so that a separate stop is superfluous.
  • the inner ends of the recesses adjacent to the mouths of the recesses (in cooperation with the associated centering projections) effectively limit the axial insertion movement of the press jaw set accommodated on the quick-change tool in a position in which the fixing projections are opposite the mouths of the recesses and thus the turning of the press jaw set, which forms the second phase of the insertion movement, is possible.
  • the above-explained recess extending to one of the end faces of the base jaw in question can also be provided on the opposite side surface instead of on that side surface of the base jaw at which its recess opens.
  • the recess of the adjacent base jaw opens into the recess or the recess of a base jaw forms the "feeder" for the fixing projection on the adjacent base jaw to be mounted to the recess of the relevant adjacent base jaw.
  • the radial depth of the recesses provided according to the invention can depend on the respective requirements. In the interest of the base jaws being made as stable as possible, the recesses are preferably not deeper than is necessary to achieve the advantages sought in the individual case. In this sense, the recesses are generally less deep than the receptacles for the fixing projections. This typically concludes the assembly of the press jaws with a radial movement of the base jaws and press jaws relative to one another (known from known machines, albeit less long here), be it through a radially inward movement of the base jaws in the sense of closing the radial press or a Radially outward movement of the press jaws (for example using a quick-change device according to the conception of the DE 20109212 U1 ).
  • the depth of the recesses can also correspond to the depth of the receptacles, so that the pressing jaws can also be assembled without radial movement of the base jaws and pressing jaws relative to one another (for example when the radial press is completely closed; see above). In this case, the pressing jaws are locked to the base jaws towards the end of the rotary movement.
  • an extension of the recesses in each case along a helical line can prove to be advantageous.
  • the recess it is also possible for the recess to continue beyond its opening on the side face of the base jaw in the adjacent base jaw (possibly up to its end face).
  • the edge-side recesses described further above can also be provided in order to achieve the stated advantages associated with them.
  • At least two geometrically differently designed fixing projections and / or at least two geometrically differently designed receptacles are provided.
  • Such a geometrical individualization of at least one fixing projection or at least one receptacle makes it possible to achieve that the press jaw set can only be mounted in a single, predefined position in the base jaws of the radial press.
  • This development can be used, for example, when using a press jaw set in which one of the press jaws - for marking the workpiece - has embossing types; because the corresponding marking press jaw should always be mounted on the lowest base jaw.
  • a preferred, exemplary embodiment is that the fixing projection of one of the pressing jaws has such a thickening that this fixing projection does not find space in the usual free spaces between each two base jaws of the (open) radial press, but only in the one single space expanded by a recess (see above).
  • Yet another preferred development of the present invention is characterized in that the locking device (each accommodated in the base jaws) exerts a radially outwardly directed prestressing force on the fixing projection that interacts with it. In this way, the locking device pulls the respective press jaw radially outward for secure, play-free contact with the press jaw support surface of the associated base jaw. In this way, the reproducibility of the radial press and, as a result, the manufacturing accuracy of the radial press can be increased.
  • a bore is provided on the front side of the base jaw through which the locking device can be unlocked.
  • Such bores can be used in a radial press system, which comprises a radial press, a press jaw magazine with set-wise stored, interchangeable press jaws suitable for attaching them to the base jaws of the radial press and a quick-change device with a handle and a press jaw holder that enables the common press jaw change
  • the quick-change device furthermore has an unlocking arrangement with unlocking elements which can be introduced into the bores of the base jaws at the end, wherein the pressing jaw holder and the unlocking arrangement of the quick-change device can be rotated relative to one another about a tool axis.
  • the quick-change device in Implementation of the present invention - rotate the pressing jaws relative to the base jaws for their assembly or disassembly, with the unlocking elements provided on the quick-change device simultaneously unlocking the locking devices. It is particularly advantageous if the press jaw holder of the quick-change device is non-rotatably connected to its handle.
  • unlocking elements used to unlock the locking devices can, however, also be designed in a wide variety of other suitable ways.
  • mechanically acting unlocking elements such as pins, bolts or the like come - with an appropriate design of the locking devices - for example, contactless unlocking elements into consideration, such.
  • Such unlocking elements are also expediently part of an unlocking arrangement which - about the tool axis - can be rotated relative to the press jaw holder.
  • the base jaws for their part are by no means necessarily made in one piece. Rather, they can also be constructed in several parts, in that they each comprise an intermediate jaw - placed on a base jaw base - on which the pressing jaw support surface is implemented. It should also be mentioned that the pressing jaw support surfaces and the mating surfaces are typically designed according to a circular cylinder section, but this is not mandatory; because deviating geometrical designs of the separating surfaces between the base and pressing jaws can also prove to be favorable in individual cases.
  • the press bodies are guided so that they can be moved radially to the press axis is not to be understood as limiting in the sense of a purely radial movement in a plane perpendicular to the press axis; Rather, as is customary with certain radial press designs based on the pressure plate concept, the press bodies can also experience a certain axial displacement during pressing, so that the movement of the press bodies when they approach the press axis and when it is removed from it in addition to the radial component can also have an axial component.
  • the "locking devices” can also ensure that the pressing jaws are fixed to the respectively assigned base jaw in some other way, for example by means of a clamping effect, by means of magnetic forces, or the like.
  • Radial press 2 shown in detail and having eight such base jaws, has, in a manner known as such, roughly approximately a wedge-shaped shape.
  • a guide groove 5 with a T-shaped cross-section is provided on a first end face 4 of the base jaw 1, which cooperates with a guide block designed as a sliding block that is mounted on the support disk 3.

  • the two side surfaces 7, 8 are oriented approximately at an angle of 45 ° to one another, so that the opposing side surfaces 7, 8 of two adjacent base jaws 1 run at least substantially parallel to one another.
  • the base jaw 1 has a receptacle 11 for a pin-like fixing projection 12 arranged radially on the inside, approximately in the center of the pressing jaw support surface 6, which radially on the outside - on the one intended to rest on the pressing jaw support surface 6 of the associated base jaw 1, also approximately in accordance with a circular cylinder section executed counter surface 13 of the press jaw 14 - protrudes from the press jaw 14 to be mounted on the base jaw 1.
  • the position of the press jaw 14 placed on the base jaw 1 is secured by the interaction of a locking device 15 integrated in the base jaw 1 with the pin-like fixing projection 12 of the press jaw 14 engaging in the receptacle 11 by positive locking.
