Definitions

  • the invention relates to a device for processing of round bodies, in particular for pressing round bodies such as pipes or of support sleeves, with which pipes and / or fittings are to be connected.
  • a device for rotational operations which can be used in particular for the pressing of round bodies.
  • the device includes a handle and a WälzSystemung which is rotatably mounted in the handle in one direction.
  • About radially inwardly adjustable rolling elements can be pressed with such a device grooves in a pipe joint.
  • a rolling element holder is rotatably mounted in a handle and the rotation is done for example via a coupled power tool.
  • a hand tool for chopping nuts and the like which includes a hand-rotatable cylindrical rubbing drum with outwardly facing rub tips.
  • the rubbing drum is rotatably mounted in a first half-shell, which is arranged at the first end of a handle.
  • the other end of the handle is pivotally connected to one end of a bracket, the other end has a cylindrically curved pressure surface, with which regrind can be pressed onto the rubbing drum.
  • a device for pressing metal sleeves on hoses in which radially displaceably mounted jaw body by radial inward movement, the desired compression cause.
  • the radial inward movement of the jaw body is generated by a rotation of annular plates which surround the jaw members in an annular manner and have at their inner contour in the circumferential direction inclined pressure surfaces with which they press the jaw body radially inwardly.
  • the device is characterized in that the handle has two bearing shells, which can be moved apart like a pair of pliers and which can receive the rolling element holder in a rotatable manner between them.
  • the pincer-like receiving the WälzSystemung between the bearings can be achieved that the WälzSystemung "closed pliers" is firmly and captively connected to the holder. At the same time can be achieved in this way a particularly simple connection of WälzSystemhalterung and handle.
  • the position of the rolling element holder can be fixed on a round body to be pressed, in particular its radial (rotationally fixed) and axial position on a support sleeve (compression sleeve).
  • a holding means for a rotationally fixed connection of the round body with the handle (or other stationary element) can be provided.
  • the device may optionally include a locking mechanism by which the rotation of the rolling element holder can be locked relative to the handle in one direction.
  • a locking mechanism by which the rotation of the rolling element holder can be locked relative to the handle in one direction.
  • the handle may have a drive shaft to which a manual or mechanical rotary drive can be attached, wherein a rotation of the drive shaft rotation of the roller body relative to the handle to the handle Working axis causes.
  • the drive shaft may be formed, for example, as a pin of round or polygonal cross-section, which fits into the drill chuck of a drill or a cordless screwdriver, so that the drive shaft can be machined.
  • a (polygonal) shaft optionally also a wrench can be applied, for example, a ratchet wrench to turn the drive shaft manually.
  • the rotation of the drive shaft can be implemented, for example via gears in a rotation of WälzSystem Highway relative to the handle.
  • the described pressing device has the advantage that it enables the simple use of mechanical rotary drives for the machining (eg the pressing) of round bodies.
  • the rolling element can also be or contain a cutting blade. Then z. B. pipes are cut off with the device.
  • each processing body In embodiments of the invention in which two or more processing bodies are present, they are preferably arranged axially spaced with respect to the working axis. When rotating around a round body, each processing body thus acts on a different circumferential line.
  • the round body For machining a round body, this is to be introduced into the press room of the rolling element holder. If the rolling element holder surrounds the pressing space in an annular manner, the round body can only be introduced from the side into the pressing space. This is unfavorable or even impossible with long pipes.
  • the round body (tubes) into the pressing space of WälzSystemhalterung even in such cases, the latter is preferably constructed of at least two components which can be separated for insertion of the round body in the press room and then closed in a ring around the round body.
  • the WälzSystemung consist of two partial circles, which together form a ring and which are hingedly connected together at one end, so that they can be transferred to an open position and a closed position.
  • the handle on storage means for a positive engagement on the workpiece may have key surfaces which engage an external hexagonal shape of the workpiece in order to fix it rotationally fixed relative to the handle.
  • the device consists essentially of two components, namely a handle 100 and a separable trained WälzSystemung 200th
  • the WälzSystemung 200 serves to record a machined round body (not shown) in a press room P, wherein the WälzSystemung then by rotation about a working axis A, which leads through the pressing space P, can edit the round body from all sides.
  • the machining consists in particular in that rolling elements 204 press in the form of pressure rollers on the round body and so for example encircle circumferential grooves in this.
  • three rolling elements 204 are provided, which are arranged offset in the direction of the working axis A and which can each rotate about an axis parallel to the working axis A.
  • the aforementioned pressure rollers are just one example of the general case of "rolling elements” with which a workpiece can be machined under pressure.
  • Another example of a rolling element 204 is a cutting blade (eg disc-shaped), with which a pipe or the like can be cut off.
  • the following explanations thus also apply analogously to other rolling elements 204.
  • said rolling element holder 200 is mounted in the handle 100.
  • the inclusion of WälzSystemung 200 in the handle 100 is gradually in the FIGS. 1 . 2 and 3 illustrated.
  • the handle 100 in an open Condition in which a clamping lever 108 is issued from a handle 113. Since the cocking lever 108 and the handle 113 are rotatably connected via a bearing pin 114, components of the handle 100 fastened in this way at the opposite ends can be moved apart like tongs.
  • These components comprise, in particular, a first bearing shell in the form of a key disk 102 and a mirror-inverted second bearing shell in the form of a guide disk 110.
  • the guide disk 110 and / or the key disk 102 can optionally be shaped and dimensioned in such a way that they form-fittingly engage corresponding key surfaces of the round body (pipe, compression sleeve, etc.) to be machined, and thus prevent it against rotation (together with the rolling body support 200). can fix. Additionally or alternatively, an axial fixation on the round body can be carried out in this way.
  • the handle 100 has a drive shaft 111 which protrudes laterally from a support bearing plate 104.
  • the drive shaft 111 has at its end a polygonal cross section, to which, for example, a polygonal wrench or ratchet wrench for a manual rotation of the drive shaft can be attached.
  • a polygonal wrench or ratchet wrench for a manual rotation of the drive shaft can be attached.
  • the chuck of a machine such as a drill or a cordless screwdriver can be set in order to turn the shaft 111 by machine relative to the handle 100 can.
  • a (small) gear 116 is mounted in the axially inner region on the shaft 111, which in the assembled state of Handle 100 and WälzSystemung 200 engages the gear 207, 208 of the WälzSystemung.
  • a rotation of the drive shaft 111 thus leads to a rotation of the WälzSystemung 200 about the working axis A.
  • standard tools cordless screwdriver, drill
  • the pressing can also be performed manually, in which a corresponding tool key is attached to the drive shaft 111 and moved by hand.
  • a locking mechanism between the handle 100 and the WälzSystemung 200, which allows rotation of the tool body holder 200 only in one direction of rotation.
  • This could be achieved, for example, by a pawl (not shown) mounted on the handle 100 meshing with the teeth of the toothed wheel 207, 208 and thus allowing rotation of the roller body support 200 in one direction only.
  • a rotation of the WälzSystemung could be generated by a round body by an oscillating reciprocation of the handle (see. DE 103 42 172 A1 ).
  • FIGS. 4 and 5 separate views of WälzSystemung 200 are shown, wherein for better visibility of the inner parts, the side plate 202, the clamping lever 206, and a pawl 216 are shown detached. From the figures, in particular the mechanism for a radial readjustment of the rolling elements 204 can be seen.
  • the rolling elements 204 are each mounted rotatably on a support / lever 203, wherein the lever 203 in turn about pivot pin 205 are pivotable.
  • the rolling elements 204 opposite end of the lever 203 abuts an eccentric shaft 209, wherein each of the three existing lever 203 scans another contour of the eccentric shaft 209.
  • each of the rolling elements 204 can thus be radially adjusted according to its own program. In particular, it is possible that initially only a first rolling element 204 is moved radially inwardly until it has reached an end position. Subsequently, a second rolling element is moved radially inwardly until he has reached its final position. Finally, finally, the last rolling element is moved radially inward until it reaches its final position. With further rotation of the eccentric 209 all scanned contours can then jump back to their initial value, whereby the rolling elements 204 back to their radially outer starting position and thus release the machined pipe for removal.
  • the various scanned contours of the eccentric shaft 209 are best viewed in the exploded view of FIG. 6 recognizable.
  • a latching disc 210 is provided at each end of the eccentric shaft.
  • the pawls ensure on the one hand that the eccentric shaft 209 can only rotate in one direction of rotation.
  • an active rotational thrust of the eccentric shaft 209 can be generated by the pawl 216 engaging in the locking disk 210 entraining the eccentric shaft 209.
  • the radial adjustment of the pressure rollers can be easily adapted to different types of pipes to be compressed by a tube-specific eccentric shaft 209 is inserted into the WälzSystemhalterung 200.
  • the WälzSystemung 200 is shown closed annular. In this state, it can only be slipped over from the front side over a pipe (not shown). If this is not possible, the WälzSystemung 200 are also opened to be placed on the side of a pipe. After placing the rolling element holder can then be closed around the pipe. For unfolding, the toothed wheel on the side of the rolling body holder is formed, for example, in two parts from a C-shaped segment 207 and a shorter folding segment 208, which can be unfolded if necessary. In FIG.
  • a pivotable bracket 213 can be seen, which connects the pressure shell 201 and the flap segment 208 of the gear with the rest of the WälzSystemhalterung in the closed state. By disengaging this clip, the said parts can then move about an axis X ( FIG. 5 ), whereby the ring of WälzSystemhalterung opens.
  • FIG. 8 shows a one-sided support sleeve S (press sleeve) before attaching an associated plastic pipe R on the provided with annular gaps support sleeve.
  • the state after the insertion of the plastic pipe R and after the compression of the support sleeve S and plastic pipe R with the device according to the invention is in FIG. 9 shown.
  • Clearly visible are three compression grooves V, which were generated by the pressure rollers 204.
  • any other workpieces / fittings can be processed or pressed with the device, in particular double nipple to which a tube can be connected on both sides (mirror-symmetrical).
  • the radial (circumferential) and the axial position of the handle on the workpiece fixed.
  • a positive engagement can take place on a non-circular outer contour of the workpiece (in particular on wrench surfaces) or on radially protruding collar of the workpiece.
  • FIG. 10 thus shows on the left a page prepared for pressing and on the right a still free side of a two-sided support sleeve S '.
  • the figures further show a handle 100 of the type described above in which substantially only the key plate 102 'is different from the previous embodiments.
  • the key disk 102 'is in fact provided with key surfaces with which it can engage the outer hexagon AS of the compression sleeve H in order to support the sleeve in a rotationally fixed manner relative to the handle 100. In this way, co-rotation of the compression sleeve H during the pressing process is excluded.
  • the guide plate 110 'of the handle 100 is mounted in a receptacle N of the workpiece to be pressed with lateral stops to fix this in the axial direction.
  • FIG. 12 A separate perspective view of the compression sleeve H with the external hexagon AS is in FIG. 12 shown.
  • FIG. 13 shows a side view (right partially in section) and FIG. 14 a perspective of the two-sided support sleeve S 'of Figures 10 and 11 , Symmetrical to the central receptacle N has the support sleeve S 'two extensions with circumferential sealing teeth on the outer surface, which dig when pressed into a tube. Furthermore, optionally, an anti-rotation device can be provided, which prevents rotation between the support sleeve S 'and a plugged-on tube (during compression and also later in continuous use with flowing media in the load change of hot / cold liquids and pressure surges in the pipe system).
  • the anti-rotation device may for example consist of a knurling (not shown), which is preferably mounted in the region marked "X" near the receptacle N on the outer surface of the support sleeve S 'and / or on the sealing teeth (eg realized by approx. 1 mm deep and about 1 mm wide grooves).
