Definitions

  • the invention relates to a method for producing a tubular member, in particular a built camshaft, by means of hydroforming, wherein a support tube and an end piece are fed, wherein inserted into an opening of the tail an associated end of the support tube and subsequently expanded by the application of a pressurized fluid and is connected to the end piece in a press fit, and wherein the opening before the pressurization with the fluid having a first portion having an inner cross section which is greater than the outer cross section of the associated end of the support tube.
  • the invention also relates to a set of components for the production of a tubular component, which has a carrier tube, an end piece with an opening for the carrier tube and for the arrangement on the carrier tube provided functional elements, such as cams.
  • camshaft Under a built camshaft is understood a camshaft, which is not manufactured in one piece in a Ur- or forming process, but assembled by the combination of several prefabricated parts. Modern built camshafts in addition to cams have additional functional elements, such as tail, sprocket, pulleys, encoder wheels, pump drives, bearings, plain bearings or the like, which must be mounted on a support tube with a suitable joining technology, with very high angular accuracies must be observed.
  • additional functional elements such as tail, sprocket, pulleys, encoder wheels, pump drives, bearings, plain bearings or the like, which must be mounted on a support tube with a suitable joining technology, with very high angular accuracies must be observed.
  • cams and optionally provided further functional elements are first pushed onto their hubs with a game on the support tube and positioned, in which case the support tube is subjected to a high internal pressure, whereby the support tube expanded with an elastic and a plastic portion and to the Inner surface of the hubs is created.
  • the cams and optionally provided further functional elements are widened to a certain extent, but this expansion preferably takes place only elastically.
  • both the support tube and the elements arranged thereon resiliently spring back, wherein the materials of the joining partners are selected so that the cams and other functional elements are held with an elastic residual stress in a press fit on the support tube.
  • the hydroforming is usually carried out in a mold, which limits the radial expansion by the pressurization. If according to a preferred embodiment of the hydroforming process, the carrier tube is acted upon over its entire length with a pressurized fluid, a sufficient seal is to ensure. Furthermore, the reliable transmission of high torques should be made possible in the hydroforming with the least possible use of materials and with a lightweight design.
  • a pressure source is usually connected to one end of the support tube while the end of the support tube opposite the pressure source must be closed pressure-tight, to which end pieces can be used, which are mounted like a cap.
  • Another variant is the possibility of pressure medium filling through an axial bore in the tail. The tube is sealed pressure-tight on the opposite side. A reliable seal is necessary to avoid the uncontrolled discharge of pressure fluid and thus an impairment of the joining process.
  • a method for producing a built camshaft with the features described above is known from DE 36 16 901 A known.
  • the production of the tubular component in the form of a built camshaft takes place in a closed mold, wherein a source of the pressurized fluid is connected to one side of the support tube and on the other side an end piece is pressed onto the local end of the support tube during the hydroforming process.
  • various measures are proposed.
  • the arrangement of a sealing ring in a radial groove or at the bottom of the opening of the tail is expensive, which due to the very high acting pressures during hydroforming typically 2000 to 5000 bar leaks in the polymeric sealing material can not be excluded.
  • the opening in the form of a blind bore at its bottom with a frusto-conical bevel against which the support tube is pressed.
  • a linear contact is achieved around the circumference, which can not ensure a reliable seal with dimensional deviations, ovality and local damage.
  • the production of such conical surfaces at the bottom of the opening is expensive.
  • the invention has for its object to provide a method for producing a tubular component, in which by means of hydroforming an end piece can be attached in a simple manner with a high reliability and reproducibility. Furthermore, a set of components is to be specified, which is suitable for carrying out the manufacturing process.
  • the object is achieved in that, starting from the front edge of the opening to the first portion, a second portion having a second inner cross section, which is smaller than the outer cross section of the associated end of the support tube, under training a circumferential edge connects in steps, wherein the support tube is first inserted with its corresponding end in the first section and wherein in a further insertion movement, the edge is cut into the material of the support tube.
  • the usually approximately rectangular step defines a comparatively sharp cutting edge, which engages when inserting the associated end of the support tube in the region of the end face of the support tube and there cuts into the material. In this cutting both a material deformation and a certain Materialabscherung can be done.
  • the end piece is prefixed after insertion of the support tube by the cutting of the edge to a certain extent, so that the support tube with the attached end piece can be handled easily before finally the joining takes place by means of internal high pressure.
  • the comparatively sharp edge cuts along the edge End face of the support tube, wherein the introduction of force initially has a considerable axial portion, whereby reinforced material deformation or shearing and less bending of the support tube takes place.
  • the height of the step is selected such that the second internal cross-section provided from the step is greater than the internal cross-section of the associated end of the tube. This difference in diameter results in the joining play for the pre-assembly.
  • the dimensions are preferably also chosen so that despite the formation of the stage, the support tube to a bottom of the opening or at least to just before the bottom of the opening in the region of the second section under deformation and / or shearing of a portion of the tube material can be inserted.
  • the second section which is preferably between 1 mm and 8 mm, preferably about 4 mm, a sealing material contact is achieved, so that local unevenness, imperfections or the like even at a pressure of several 1000 bar not lead to a noticeable reduction of the seal.
  • An extension of the second portion may be useful to compensate for uneven shortening of the tube as a result of forming operations.
  • the fact that the support tube can preferably be inserted with its end to the bottom of the opening also results in terms of dimensional accuracy of a particular high accuracy and reproducibility, since the bottom of the opening as it serves as a stop for the associated end of the support tube.
  • the present invention generally relates to a method for manufacturing a tubular member, wherein the cross-sectional shape of the support tube is not initially determined.
  • the cross-sectional shape of the support tube is not initially determined.
  • square, rectangular, elliptical or other cross-sectional shapes are conceivable, wherein a peripheral edge is always provided at the transition of the first section to the second section within the opening of the end piece, wherein the inner contour of the opening is adapted to the outer contour of the support tube.
  • a circular cross-section is usually provided, so that the sections of the opening are preferably circular-cylindrical or substantially circular-cylindrical.
  • the details of the dimensions with respect to the inner and outer cross sections relate to a circular configuration according to the inner and outer diameter.
  • the quality of the seal on the one hand and the force required for insertion of the support tube in the associated end piece on the other hand depend on the determination of the dimensions, the second inner cross section, the length of this section and the outer cross section of the tube.
  • the first inner cross-section relative to the second inner cross-section in the radial direction has an excess between 0.1 mm and 1 mm, particularly preferably between 0.2 mm and 0.4 mm, which measure the height of the corresponds to a substantially right-angled step between the first section and the second section.
  • the game between the first inner cross section and the outer cross section of the associated end of the support tube is preferably small and usually just chosen so that a jam-free pushing can take place.
  • the first inner cross section with respect to the outer cross section of the associated end of the tube in the radial direction an excess of less than 0.2 mm, more preferably between 0.05 mm and 0.1 mm.
  • the opening has a longitudinally extending total length, which is at least 60%, preferably at least 80% of the inner diameter of the first section. Based on the finished component, the length along the longitudinal direction of the support tube is to be determined.
  • the outer joining partner has a greater elastic recovery than the inner support tube. Accordingly, a sufficient expansion of the outer joint partner must be carried out beforehand, for which it may have a not too large wall thickness. So is provided according to a preferred embodiment, that the end piece in the region of the first portion of the opening has a wall thickness between 2 mm and 4 mm and so can be expanded elastically in the hydroforming to a sufficient extent.
  • the opening of the end piece can be pretreated before insertion of the associated end of the support tube with a particle beam, such as a corundum, a shot blasting, sandblasting or the like. This increases the coefficient of friction between the joining parameters. In order to avoid damage to the invention as sharp as possible edge at the transition from the first portion to the second portion of the opening, this can be covered during the pretreatment by the particle beam.
  • a particle beam such as a corundum, a shot blasting, sandblasting or the like.
  • connection strength can be further increased. Training is understood to be the generation of an additional relative movement between the joining partners, for example a twisting or shifting in alternating directions.
  • the contouring may, for example, have the form of a spiral, a pocket, an inner knurling, a butted inner contour or the like. Contours in which the formations run transversely to the direction of the torque transmission are particularly advantageous.
  • the pipe material is molded into the corresponding contouring, whereby in addition to the adhesion and a positive connection is formed.
  • the formation of a contouring requires a correspondingly high wall thickness of the tail, which counteracts to some extent elastic extensibility.
  • the hydroforming takes place within the scope of the invention expediently within a mold.
  • functional elements such as cams, sensor wheels, bearing rings or the like are threaded onto the carrier tube in the desired sequence, wherein the end piece is also attached at one end of the carrier tube as described above.
  • the support tube and the functional elements threaded thereon are then inserted into a tool mold and thereby aligned with respect to their axial position and rotational angle alignment.
  • the carrier tube is at a given Pressure as far as required for shaping and fastening required.
  • the pressure source may, according to a preferred embodiment, be moved axially to keep the tube tight and to compensate for shortening of the tube due to the bulge.
  • hydroforming can also be used to form functional surfaces such as bearing points from the support tube itself. This results in the advantage that due to the plastic deformation up to the tool shape, certain dimensional deviations of the carrier tube originally used are compensated. For the dimensional accuracy, in essence, only the provision of the support tube after elimination of the internal high pressure is decisive.
  • bearings on sections of the support tube they may, for example, also be subjected to finish machining and / or coating before hydroforming.
  • the carrier tube or the end piece are not completely cleaned, if despite the good seal in the region of the tail at least at the beginning of hydroforming certain amounts of pressure fluid in the joint gap or in the lower mold emulsion residues of previous forming operations, there is a risk that in the joint gap, a liquid film is formed which, as a kind of counter cushion and spacer, counteracts the forces exerted by the internal high pressure. It can then not be ruled out that the interference fit between the joining partners is impaired and / or that certain production fluctuations occur. In order to avoid such an impairment, is provided according to a preferred embodiment of the invention that at the beginning of hydroforming liquid can be removed from the joint gap between the carrier tube and tail.
  • the end piece in the region of the first portion of the opening may have at least one radial discharge channel, for example in the form of a bore and / or at least one groove extending in the longitudinal direction.
  • the expanding support tube is damaged at the edge of the opening, there may be provided between the first portion and the edge of the opening, a radius and / or a conical widening. A cutting into the widening support tube can be avoided.
  • the formation of a radius or a conical extension at the edge of the opening also contributes to the fact that the tail can be even more easily placed or preassembled on the associated end of the support tube.
  • the invention also relates to a set of components for producing a tubular component by means of hydroforming, wherein the component set has at least the carrier tube and end piece described above.
  • Fig. 1 shows the general structure of a formed by hydroforming camshaft having a support tube 1, at one end of the support tube 1, an end piece 2 and a plurality of functional elements in the form of cam 3 and a thrust bearing 4.
