Definitions

  • the invention relates to a crimping attachment for expanding cylindrical pipe ends for an automatically operable handheld device according to the preamble of claim 1.
  • the invention also relates to a set of such crimping attachments for different pipe diameters.
  • flanging tools are known.
  • manual crimping tools are known, which are formed like pliers. In this case, first the tube end is fixed with radially to each other movable jaws and then delivered a flaring axially to the pipe end to widen this to the desired extent.
  • Such crimps are designed especially for smaller pipe diameters and softer pipe materials, since manual operation requires a relatively large amount of force.
  • a crimping device which may be formed as a cap which is attachable to an electrically driven hand drill.
  • the adapter has two plate-shaped clamping jaws, between which a tube can be clamped.
  • the two plate-shaped clamping jaws are screwed together or clamped to each other via other clamping devices.
  • the two plate-shaped clamping jaws are equipped with mutually corresponding half-shell-shaped receptacles for a tube.
  • For the determination of tubes of different diameters each have several different sized half-shell-shaped receptacles are recessed in the plate-shaped jaws.
  • a threaded rod In a threaded bore opposite a receptacle, a threaded rod is rotatably mounted, at the front end of which a flanging iron or an expander device is arranged.
  • a flanging iron or an expander device By turning the threaded rod the crimping iron is delivered to the pipe end to be expanded.
  • the turning of the threaded rod for example, by means of the spindle drive of the hand drill.
  • the handling of this designed as an attachment crimping device is relatively cumbersome. First, the tube must be clamped between the jaws. Care must be taken to ensure a correct distance of the pipe end from the flaring iron, so that it can be widened to the correct extent.
  • the advance of the crimping iron attached to the threaded rod is predetermined by the steepness of the thread of the threaded bore or the threaded rod. Nevertheless, the feed is not exactly controllable, since the drive of the threaded rod on the rotary spindle of the hand drill is only relatively inaccurate. If the crimping iron is driven in each case to stop during operation, this can lead to damage of the crimping iron or even the drive of the hand drill.
  • the crimping attachment should allow an exact and reproducible expansion of a cylindrical pipe end.
  • This pipe ends of pipes of different materials such as copper, brass, steel, Plastic (eg PEX), with or without plastic coating, easy to expand.
  • the crimping attachment should be operable with electric, pneumatic or hydraulic drives.
  • Another way to operate the crimping attachment can also be done with a pair of pliers, preferably with a hydraulic pliers. A time-consuming retooling for different pipe diameters should be avoided.
  • the present invention designed flare is designed for operation with an electrically, pneumatically or hydraulically operated hand-held device.
  • the crimping attachment for expanding cylindrical tube ends has a connection interface for the hand-held device, clamping devices for a cylindrical tube and a widening device.
  • the expansion device can be delivered axially onto a pipe end fixed by the clamping device in order to widen it to the desired extent.
  • the clamping device and the expansion device are coupled together via a limited axially displaceable coupling member and sequentially activated. By the clamping device and the expansion device are coupled together, eliminates the cumbersome clamping of the tube in the clamping device before the actual expansion process can take place.
  • the clamping of the tube and the expansion process via a single limited axial displacement of the coupling element via a single limited axial displacement of the coupling element.
  • the clamping process and the expansion process are triggered sequentially by the axial displacement of the coupling element.
  • the axial displacement of the coupling element takes place with the aid of the electrically, pneumatically or hydraulically operable drive unit, preferably with a hand-held unit, with which the crimping attachment is connected via its connection interface.
  • the pipe end is thus widened by machine. This eliminates physical effort, as they are required, for example, in the operation of known crimping pliers.
  • the clamping device is disposed within a cylindrical housing.
  • the clamping device has a number annularly arranged clamping jaws with clamping areas, which are automatically radially deliverable upon insertion of a cylindrical tube on a jacket of the tube to set this.
  • the expansion device is formed as a substantially conical Aufweitdorn mounted on a substantially coaxial with the annular arrangement of the jaws extending push rod and deliverable axially to a pipe end of the fixed pipe.
  • the push rod is arranged to be axially displaceable in an axial bore of the coupling element designed as a control sleeve.
  • control sleeve On its outer surface, the control sleeve on control tracks for a radial tilting of the jaws.
  • the control sleeve is so limited axially displaceable against the restoring force of a return spring, that the inserted tube can be fixed on the radially deliverable jaws before the mandrel is axially deliverable to the pipe end.
  • the control sleeve, the guided in the bore of the control sleeve push rod with the expanding mandrel and the annularly arranged jaws have within the cylindrical housing a space-saving, substantially coaxial arrangement.
  • This arrangement makes it possible to convert the limited axial displaceability of the control sleeve on the control tracks on the outer surface of the control sleeve in a radial movement of the jaws on each other.
  • the arrangement of the control sleeve ensures that the push rod with the expanding mandrel is only then delivered to the pipe end, after the pipe has been fixed sufficiently firmly by the jaws.
  • the activation of the crimping attachment is essentially limited to the limited axial displacement of the control sleeve, which is done by the electrically, pneumatically or hydraulically operable handset.
  • the fixing of the tube and the expansion of the pipe end are carried out automatically.
  • the return spring ensures that the control sleeve is moved back to its original position at the end of the crimping process.
  • the push rod is withdrawn with the Aufweitkonus, and the jaws release the tube with the widened pipe end to the desired extent again, so that it can be pulled out of the Bördelaufsatz.
  • a variant of the inventive crimping attachment can provide that the clamping jaws are tiltably mounted within the cylindrical housing. In this case, their end sections facing away from the clamping regions interact with the control tracks on the outer surface of the control sleeve.
  • This simple design allows the transmission of clamping forces in the desired extent on the tube end inserted into the essay. These are essentially only dependent on the course and on the steepness of the control tracks on the outer surface of the control sleeve.
  • the end sections of the clamping jaws are loaded by pressure bolts whose free ends preferably form receptacles for rolling elements which are in engagement with the control tracks on the outer surface of the control sleeve, the clamping jaws can very reliably follow the course of control tracks. A function of the detrimental friction of the interacting components can be largely avoided.
  • the clamping force with which the clamping jaws define the inserted tube end can be selectively controlled via the course of the control tracks on the outer surface of the control sleeve.
  • a variant of the Bördelaufsatzes can therefore provide that the control tracks on the outer surface of the control sleeve are at least partially formed such that with increasing axial displacement of the control sleeve against the restoring force of the return spring, the clamping force of the jaws can be amplified. This is achieved, for example, by a change in the pitch of the control track, which results from a section-wise enlargement of the outside diameter of the control sleeve.
  • control tracks on the outer surface of the control sleeve can have one or more regions which are designed in such a way that, after a predetermined clamping force has been reached during a further axial displacement of the control sleeve the clamping force is constant.
  • a Such embodiment of the invention may be of interest, for example in Bördelauf mechanismsn, which should be used primarily for the expansion of the pipe ends of plastic pipes. It can also be provided that the Aufweitkonus remains over a longer period in engagement with the pipe end, so that an elastic recovery of the expansion can be counteracted.
  • control tracks can also be actuated by the axial displacement of the control sleeve, a trigger that activates a hydraulic Betuschistsmechnismus for the jaws.
  • hydraulically radially displaceable push rod can cooperate with the end portions of the jaws to tilt the jaws in their clamping position.
  • Another embodiment of the invention may also provide that the jaws are manually slightly radially apart, for example, to facilitate the insertion of a tube in the crimping or the removal of a tube with flared pipe end.
  • the cylindrical housing relative to the jaws and against the restoring force of a tension spring limited in the direction of the Anbinde4.000stelle be displaced.
  • a projecting from an inner surface of the cylindrical housing and at least partially circumferential projection which normally presses on the jaws is thereby displaced and releases the jaws.
  • At the insertion end of the housing cooperating with the clamping jaws forced operation is arranged, via which the jaws are pressed radially outwardly during axial displacement of the housing.
  • the restoring force of the tension spring for the housing is greater than the restoring force of the return spring for the control sleeve. This ensures that the housing is not moved unintentionally with the axial displacement of the control sleeve.
  • a further embodiment of the invention can provide that the clamping jaws are arranged such that their longitudinal axes with each other enclose an angle which is greater than 0 °.
  • the jaws are inclined with respect to the longitudinal axis of the crimping attachment at an angle of about 1 ° to 15 ° in the opening direction, so that the jaws are always slightly V-shaped to each other. As a result, the insertion of a pipe end is facilitated in the crimping attachment.
  • control sleeve may also be accompanied by a rotational component.
  • control tracks are formed on their outer surface as curved tracks.
  • a simple embodiment of the invention may provide that the return spring and the tension spring are helical compression springs.
  • Helical compression springs are available in all desired strengths and have been tried and tested. It will be understood, however, that with minor structural modifications, which are within the skill of those of ordinary skill in the art, other types of springs or spring elements may be employed in place of helical compression springs, such as e.g. Tension springs, conical springs, leaf springs etc.
  • a variant of the invention may provide that the clamping device of the crimping attachment comprises at least three jaws and on the outer surface of the control sleeve, a corresponding number of control tracks is formed. With at least three jaws a pipe is already reliably fixed.
  • the clamping device comprises six jaws and on the outer surface of the control sleeve, a corresponding number of control surfaces is formed.
  • control sleeve To ensure the limited axial displacement of the control sleeve may be provided within the cylindrical housing an end stop.
  • the control sleeve in turn, may have a stop for the push rod connected to the mandrel.
  • a set of flare attachments is provided.
  • the Bördelauf arrangements are each formed according to one of the presented embodiments. If the user wants to machine pipes with different outside diameters, it is sufficient if he exchanges the flare attachment on the handset.
  • the connection interfaces can be, for example, screw threads, fork connections or bayonets, which interact with corresponding interfaces on the hand-held device.
  • the change of the Bördelaufsatzes can therefore be very simple, fast and usually done without tools. In contrast to flaring devices known from the prior art, therefore, a separate flanging device is not required for each pipe diameter.
  • the hand-held device can also be a universal hand-held device, which, in addition to crimping attachments, also with other attachments for further processing steps, such as e.g. Cutting, pressing, connecting by sliding sleeve technology, etc. can be equipped. As a result, the use of the handheld device can be optimized.
