Definitions

  • the present invention relates to an expansion head for expansion tools for hollow workpieces, in particular for the ends of pipes made of plastics and coated with plastics metals.

  • the expansion tools are basically of a pressing device with a mandrel which is axially displaceable in or on the housing of the pressing device and at its one axial end portion has a conical surface, wherein the opening angle of the corresponding cone is usually about 9 °, and an expansion head, the preferably via a receiving device for the expansion head on the pressing device can be fixed, constructed. At an opening angle of the cone of the expanding mandrel of 9 ° is called a so-called. Standard recording.
  • a drive device which can be driven manually or by machine, the mandrel is moved in the axial direction in the direction of the expansion head.
  • the expansion jaws of the expansion head define a central conical seat into which engages the conical surface of the mandrel displaceable in the axial direction by the pressing device.
  • the mandrel Upon actuation of the pressing device, the mandrel is pressed into the expansion head, wherein there is a contact between the conical surface of the mandrel and the receptacle formed by the expanding jaws.
  • the expansion jaws Upon further axial movement of the mandrel in the direction of the expansion head, the expansion jaws are pressed radially outward and there is a radial stroke of the expansion jaws, so that the expanding jaws the ends of a hollow workpiece, in particular a plastic pipe or a metal-plastic composite pipe in the the expansion head is inserted, widen.
  • the expansion jaws go over from the closed state to the expansion state. Upon a radial backward movement of the mandrel from the expansion head, the segments become by return means (for example, an annular spring or an elastic O-ring) moved back to its original position.
  • return means for example, an annular spring or an elastic O-ring
  • a regular expansion of a pipe end is therefore necessary to after insertion of a connecting piece by pressing with a guided over the pipe end sliding or compression sleeve (axial sliding a sliding sleeve on the pipe end with inserted therein connector in a sliding sleeve connection or radial compression of a compression sleeve via a pipe end with inserted therein connector) to achieve a tight connection.
  • the object of the present invention is to provide an expansion head for hollow tool widening tools which overcomes the disadvantages of the prior art.
  • the expansion head according to the invention should be suitable for expanding larger-sized tubes (in particular with an outer diameter of at least 40 mm), wherein the expansion head according to the invention with the usual Aufweitwerkmaschineen (which have a standard recording) should be compatible.
  • the adapter element has on its inner side a further conical surface whose opening angle is smaller than the opening angle of the conical surface formed by the conical segment surfaces on the inside of the expansion jaws.
  • the expansion head further comprises at least one restoring element, which is accommodated in the head housing and is located on one side with the adapter element in engagement, wherein the restoring element exerts a force acting in the axial direction on the adapter element at least in the expansion state.
  • the provision of an internal return element causes an independent return operation of the adapter element after completion of the expansion process.
  • the use of a plate spring has proved to be particularly advantageous as a restoring element because it can be easily integrated into the head housing.
  • an expansion head for hollow tool widening tools particularly for the ends of plastic and plastic coated metal pipes, which includes a head housing having a radially inwardly directed guide flange; a set of sector-shaped spreader jaws individually guided by an inner flange sector overlapping with the guide flange and a radial groove radially movably on the guide flange, the set of spreader jaws being movable between a closed state and an expansion state, and the spreader jaws their inside are limited by conical segment surfaces, which complement each other in the closed state of the expansion head to a conical surface; and an accommodated in the head housing, conical and axially movable adapter element, wherein the cone angle of the adapter element corresponds to the opening angle ⁇ of the conical segment surfaces and the adapter element is bounded on its inner side by a further conical surface, wherein the opening angle ⁇ of the conical surface on the inside of the adapter element smaller than the opening angle ⁇ through the conical

  • the adapter element is fixed in the head housing by an attachment means in the axial direction.
  • manufacturing tolerances and thus the game of sector-shaped expansion jaws can be optimized and / or adjusted.
  • the use of a pressed-in in the cap attachment plates, a threaded disc, a shim or a locking ring has proven to be particularly useful as the fastener.
  • the bias of the spreader jaws in the cap can be set very precisely and thereby optimized.
  • the expansion head further comprises at least one return means by which the expansion jaws from the expansion state in the closed state are traceable.
  • a return means prevents tilting or hooking of the individual expansion jaws during the return process.
  • the return means is preferably designed as an annular sleeve or annular spring, more preferably, the return means is arranged in an annular groove formed on the outside of the expansion jaws.
  • the expansion jaws may also be helpful if the expansion jaws have a taper on their side facing away from the head housing. As a result, a smooth transition between the flared and unexpanded portions of the hollow workpiece after the flaring operation can be achieved.
  • the expansion jaws may also be useful if at least one of the expansion jaws has on its outer side a sliding shoe, which cooperates with a corresponding sliding groove in the head housing. As a result, the expansion jaws are guided during the expansion process safely in the expansion head according to the invention, whereby the risk of tilting of the expansion jaws is reduced.

  • Each of the sector-shaped expansion jaws 3 is individually guided by an inner flange sector 10, which overlaps with the guide flange 6, and a radial groove 11 in the head housing 2 radially movable on the guide flange 3.
  • the mecanicflanschsektoren 10 have on their outsides Nutsektoren included in the entire circumference of the expansion head 1 to a circumferential annular groove on the outside of mecanicflanschsektoren 10, in which an annular return means 12 for the return of the expanding jaws 4 from the open to the closed state of the expansion head 1 is.
