Definitions

  • the invention relates to a method for producing a pressing tool.
  • the invention also relates to a pressing tool which can be produced by such a method.
  • Such pressing tools are usually used to connect pipe sections by pressing the pipe sections against one another by means of the pressing tool.
  • the pressing tools have at least two pressing jaws which can be moved relative to one another and between which the pipe sections to be connected can be brought. By moving the pressing jaws towards one another, a deformation force is exerted on the pipe sections to be connected and the pipe sections are pressed against one another as a result.
  • the pressing jaws are usually surface-hardened in various areas. Nitrocarburizing, for example, has previously been used as a hardening process. Due to the only small depth of hardening that can be achieved using this process, losses in service life have previously had to be accepted.
  • Press tools with surface-hardened areas are from the US 2003/046973 A1 , the EP 1 447 179 A2 and the DE 10 2006 050 799 A1 known.
  • the invention is based on the object of proposing possibilities by means of which premature signs of wear on the pressing tool, in particular its pressing jaws, are counteracted and the service life is thus extended.
  • This high dimensional accuracy of the hardening is achieved because only a small area of a surface layer is heated by the action of the laser beam and the necessary very rapid cooling takes place through the dissipation of heat into the pressing tool or the pressing jaw. It is therefore neither necessary to heat the press tool or the press jaw nor to cool it with a quenching medium in order to form the hardness layer.
  • the formation of the hard layer is therefore relatively easy to implement in terms of process technology and is therefore relatively inexpensive.
  • the blank used to produce the press jaw can be forged or made of cast, in particular investment casting.
  • the pressing jaw has or consists of a metallic alloy, in particular has or consists of steel, in particular has or consists of highly tempered steel.
  • materials with a crystalline structure are used. Such materials can be hardened or at least promote hardening close to the surface.
  • the at least one selected area can be used form the hardness layer close to the surface, whereas the rest of the press jaw still retains its ductile structure. In this way, it is avoided that in the event of an overload there is a brittle fracture and the associated bursting of the press jaw. Due to the ductile structure of the press jaw in the non-hardened areas, sufficient deformation of the material is ensured in the event of overload, so that a ductile fracture occurs at best.
  • the hard layer has a thickness of approximately 0.2 mm to approximately 1.5 mm, in particular 0.5 mm to 1.2 mm. This ensures a sufficient thickness of the hardening layer in order to achieve sufficient wear resistance and thus to achieve a long service life.
  • the thickness of the hardness layer also forms the hardening depth over which the hardness layer extends from the surface of the press jaw.
  • the thickness of the hardness layer should be essentially constant, in particular should be constant throughout.
  • the thickness of the hard layer is varied or can be varied between approximately 0.2 mm to approximately 1.5 mm, in particular 0.5 mm to 1.2 mm.
  • the press jaw has a die and at least one end face, which for
  • the at least one selected area being in the transition from the die to the end face.
  • the at least one area is affected by the hardening treatment, which area is subject to a particularly high load when the pipe sections are pressed.
  • the transition of the die to the end face affected here scrubs along the outer circumference of the pipe section to be pressed in the course of the closing movement of the pressing jaws and is therefore subject to high mechanical stress.
  • the formation of the hard layer in the transition prevents premature wear at the transition.
  • the at least one selected area lies adjacent to at least one edge or at a distance from at least one adjacent edge in the transition of the die to the end face.
  • the edge itself remains unhardened or at least largely unhardened, so that the edge still has a certain ability to absorb pressure.
  • the edge can also have a ductile structure, whereas the hardness layer is then formed in the subsequent transition.
  • the edge can be a marginal edge, for example a longitudinal edge.
  • the edge is to be understood as the area of a linear extension in which two surfaces or sides of the pressing jaw that are at an angle to one another adjoin or lie on one another.
  • the edge is thus formed by the area of the line of intersection of two surfaces or sides of the pressing jaws that are at an angle to one another.
  • the edge forms one common edge of the two mutually angled surfaces or sides of the press jaw.
  • the edge is preferably designed to be rounded or beveled.
  • the transition from the die to the end face only the section or sections with the smallest distance from the central axis of the die is or are laser-irradiated. This saves processing time, since the entire transition from the die to the end face is not laser-irradiated. Since only the section or sections with the smallest distance to the central axis of the die are laser-irradiated, the hardness layer formed in the transition is interrupted at least once or several times. This also effectively counteracts possible crack formation, for example coming over the hardened section or sections.
  • the areas in the transition of the die to the end face are nevertheless covered by the hardness layer, which are particularly mechanically stressed during pressing.
  • the central axis is to be understood as the axis coinciding with the longitudinal axis of the pipe sections to be pressed or the axis which is spaced apart in parallel and which lies in the center of the die formed by the pressing jaws.
  • the press jaw has at least one contact side with at least one contact surface against which a running or sliding element, such as a drive roller, can be brought into operative contact, the at least one selected area lying on the contact surface.
  • a running or sliding element such as a drive roller
  • An actuating device acts on this area, namely the contact side or contact surface, in order to press the pressing jaw against the pipe sections to be pressed while exerting a pressing force.
  • the contact side or the contact surface is acted upon, for example, by a drive roller of the actuating device.
  • the contact side or the contact surface is therefore subject to high mechanical stress.
  • the formation of the hardening layer prevents premature wear.
  • the selected area can extend on the contact surface into or over an inlet curve for the running or sliding element.
  • the run-in rounding is also encompassed by the hardness layer brought about by means of the laser beam.
  • the selected area extends on the contact surface and ends in front of or at an inlet curve for the running or sliding element. This saves machining time, since the run-in rounding itself is excluded from hardening.
  • the at least one selected area lies adjacent to at least one edge on the contact surface or the at least one selected area lies at a distance from at least one adjacent edge on the contact surface.
  • the edge itself remains unhardened or at least largely unhardened, so that the edge still has a certain ability to absorb pressure.
  • the edge can also have a ductile structure, whereas the hardness layer is then formed in the adjoining area of the contact surface.
  • the edge can be a marginal edge, for example a longitudinal edge.
  • the configuration according to claim 4 saves processing time, since not the entire contact area is laser irradiated.
  • the hardened layer formed is interrupted at least once or several times. This also effectively counteracts any possible crack formation, for example coming over the hardened strip or the hardened strips.
  • the contact surface can be set in a targeted manner with regard to the expansion of the hardness layer.
  • the strip or the strips are to be designed with increasing, in particular essentially linearly increasing, width, so that the resulting hardness layer in their Width increases. This increase in the width of the hardened layer counteracts tilting of the running or sliding element engaging it in a particularly effective manner and thus a high positional stability for the running or sliding element is achieved in a simple manner.
  • the configuration according to claim 5 also prevents the hard layer from breaking out at the edge.
  • the edge can be an edge of the type described above.
  • the configuration according to claim 6 and also the configuration according to claim 7 are each aimed at the advantages of the configurations of claims 4 and / or 5, the configuration according to claim 6 and the configuration according to claim 7 each being a particularly expedient configuration of the hardness layer.
  • the laser-treated strips are at a greater distance from one another at one end than at their other end.
  • a tilting of the running or sliding element engaging it is particularly counteracted in this area and thus a higher positional stability for the running or sliding element is achieved.
  • the strips should run away from one another with their longitudinal extension in the direction of the running or sliding movement of the running or sliding element carried out during the pressing process.
  • the positional stability for the running or sliding element generated by means of the strips increases as the load on the contact surface by the running or sliding element increases.
  • the strips can run on a "V" in the direction of the running or sliding movement of the running or sliding element carried out during the pressing process.
  • the widths of the strips can be essentially identical to one another.
  • the strips can also be axially symmetrical to one another with respect to the longitudinal center axis of the press jaw.
  • the strips become wider in the direction of the running or sliding movement of the running or sliding element carried out during the pressing process, preferably uniformly and / or equally larger in width to one another.
  • the surface pressure on the contact surface which increases during the pressing process as the path of the running or sliding element increases, is taken into account in order to achieve effective wear protection through the hardness layer.
  • the press jaw has a die and adjoining end faces, which each serve to form a closing joint, and has at least one contact side with a contact surface against which a running or sliding element, such as a drive roller , can be brought into operative contact, and several selected areas are laser-irradiated, of which selected areas lie in the transition from the die to one of the end faces, in the transition from the die to the other of the end faces and / or on the contact surface.
