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. Furthermore, it relates to a WälzShifferung for such a device.
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.
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.
machining body is a rolling element. Therefore, in the following, the term “rolling element” is often used interchangeably with the more general term “machining element” (and the term “rolling element support” has been used instead of “machining element support”). According to another application, the machining body can also be or contain a cutting blade. Then z. B. pipes are cut off with the device.
the device according to the second aspect is characterized in that the handle has two bearing shells which can be moved apart like a pair of tongs and which can receive the rolling body holder in a rotatable manner between them.
the device according to the second aspect may optionally additionally have the features of the device according to the first aspect. Furthermore, the explanations and definitions given above for the first device also apply analogously to the second device.
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).
the devices discussed above may optionally include a locking mechanism by which the rotation of the rolling element holder relative to the handle can be locked in one direction.
a locking mechanism by which the rotation of the rolling element holder relative to the handle can be locked in one direction.
the rolling element holder can be used in particular in connection with a device of the type described above.
the explanations given in connection with these devices and definitions therefore apply mutatis mutandis to the WälzShifricehalterung according to the third aspect of the invention.
a quasi-random "program" of the radial adjustment of the machining body can be realized in a simple and robust manner.
the progression of the adjustment program can be controlled in a simple manner by the rotation of the eccentric shaft.
the carrier may in particular be a one-armed or two-armed lever, at one end of which the processing body is mounted. Another point of the lever, for example with a two-armed lever the opposite end, can then make the scanning of the eccentric shaft. With the help of the lever, it is possible to generate very large pressure forces on the processing bodies.
the WälzShifferung contains two or more processing body, which different contours of Scan the eccentric shaft.
Each of the processing body is thus adjusted radially according to its own program, the programs of the plurality of processing body are preferably coordinated. For example, in the case of three machining bodies, first the first to a maximum value can be adjusted radially inward, then the second, and finally the third. In this way, it is achieved that only one of the machining bodies executes an active machining (eg, a compression) at a given time, so that overall the force required for the compression remains limited.
an active machining eg, a compression
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 eccentric shaft is preferably mounted so that it can rotate only in one direction of rotation. This can be realized for example via a ratchet mechanism.
the direction of rotation of the radial adjustment program can then be specified by the direction of rotation, wherein after a complete revolution (360 °) automatically the starting position of the processing body is reached again.
the eccentric shaft is in turn rotated relative to the WälzSystemung upon rotation of the WälzSystemhalterung in a handle.
the WälzSystemung and the handle causes two things, namely, on the one hand, the rotation of the entire WälzSystemhalterung relative to the handle and on the other hand, the rotation of the eccentric shaft within the WälzSystemhalterung.
the eccentric shaft rotates stepwise, namely with a respective rotational thrust at certain angular positions of the rolling element relative to the handle.
elements may be provided which touch the handle in said angular positions and thereby provide a rotational thrust of the eccentric shaft.
a rotational thrust can be triggered by a specific (small) angle of rotation after every full 360 ° revolution of the rolling body holder in the handle.
a gear can be provided on the eccentric shaft, in which engages a movable pawl of WälzSystemung.
a ratchet mechanism can be realized, which allows the rotation of the eccentric shaft only in one direction.
an active (stepwise) rotation of the eccentric shaft can be generated by the pawl is pressed in the reverse direction and thereby entrains the eccentric shaft. After completion of such a rotation thrust, the pawl can then go back to the starting position without taking the eccentric shaft.
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 the rolling body holder even in such cases, the latter is preferably composed of at least two components, which can be separated for insertion of the round body into the pressing space 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 for a positive engagement on the workpiece.
the Handle have key surfaces which engage an external hexagonal shape of the workpiece in order to fix this rotatably 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 processing consists in particular in that rolling elements press in the form of pressure rollers 204 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 rolling elements 204 are just one example of the general case of "machining bodies" with which a workpiece can be machined under pressure.
Another example of a processing body is a (For example, disc-shaped) cutting knife with which a pipe or the like can be cut off.
the following explanations thus also apply analogously to other machining bodies 204.
machining bodies eg rolling bodies and cutting blades
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 state 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 done 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 of the shaft 111, which engages in the assembled state of handle 100 and WälzSystemung 200 in 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 pressure rollers 204 can be seen.
the pressure rollers 204 are each rotatably mounted on a carrier / lever 203, wherein the lever 203 in turn about pivot pin 205 are pivotable.
the pressure rollers 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 pressure rollers 204 can thus be radially adjusted according to its own program. In particular, it is possible that initially only a first pressure roller 204 is moved radially inward until it has reached an end position. Subsequently, a second pressure roller is moved radially inwardly until it has reached its final position. Finally, finally, the last pressure roller is moved radially inward until it reaches its final position. Upon further rotation of the eccentric 209 all scanned contours can then jump back to their original value, whereby the pressure rollers 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 locking disk 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 can also be opened to be placed on a pipe from the side. 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 external 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).
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).
the key plates 102, 102 'and the guide discs 110, 110' and optionally also the side plate 101 and the support bearing 104 are interchangeable or easily convertible to process different pipe and workpiece diameters can.
a set of these elements can be used in each case for a range of pipe diameters (for example, 20-40 mm, 50-110 mm).
