Definitions

  • the present invention relates to a method and an arrangement for producing rings from a tube made of a metallic material, wherein the rings are provided on the inner circumference with an axially continuous inner profile and on the outer circumference with a radial outer profile.
  • Such a method is known, for example from the DE 102 19 441 Cl ,
  • the method described in this document is used for the production of internally and / or externally profiled rings, in particular of rolling bearing rings and gear rings, in a complete ready-to-sand state of tube or solid material.
  • a radial outer profile should be produced by radial-axial profile tube rollers.
  • a pipe section is machined from the outside with a rolling tool.
  • the resulting flow of material is influenced by a counter-pressure tool which acts in the axial direction on the machined pipe section.
  • the flow of material in the axial and radial directions is controllable, so that the evasive material can be included in the formation of the profile.
  • a radial inner profile can be formed at the same time.
  • sliding sleeves is proposed to produce the necessary internal toothing (axial profiling) by cutting in a separate operation, after the foundedachir has been completely rolled ready for grinding.
  • the axial inner profile of the rings can be produced significantly cheaper, namely by kneading. Since the metallic material used to produce the rings must be able to flow within limits anyway because of the rolling process used for producing the radial outer profile, the kneading method for producing the axial inner profile is generally applicable.
  • kneading is to be understood broadly herein and is intended to include all similar and alternative methods in which material is intermittently pressed into the profile of the profile mandrel by radial and / or axial pressure.
  • the rings according to the invention may in particular be sliding sleeves or coupling bodies, as used in transmissions.
  • the material flow may optionally be controllable from both axial sides close to the rolling tool.
  • the rolling step c) is preferably carried out on the inside profiled pipe section, wherein finished rings are subsequently separated.
  • the handling is advantageous because a large number of items only arises when the rings are completed.
  • the tube is moved in the kneading step b) relative to the kneading tool in the axial direction.
  • the axial inner profile can be formed in a continuous operation on the pipe section.
  • the kneading tool moves relative to the tube.
  • the mandrel outer profile of the first profile mandrel is shorter than the length of the pipe section, wherein the first profile mandrel is floating and wherein the pipe section is moved in the kneading step b) in the axial direction relative to the first profile mandrel.
  • the length of the tube section, on which the axial inner profile is formed in one piece can be made comparatively long, for example 50 to 70 cm.
  • the utilizable portion of an outlet tube can thus be significantly increased since the length of the profiled tube section becomes greater in relation to the length of the clamping of the tube, which is usually necessary.
  • the first profile mandrel is supported in the kneading step b) in the axial direction and thus remains substantially stationary with respect to the kneading tool.
  • a support can take place in the axial direction, preferably in the direction of movement of the pipe section relative to the first profile mandrel.
  • a second profile mandrel is arranged in the pipe section or ring.
  • the rolling step can be carried out without a material flow affecting the integrity of the already produced inner profile.
  • an axial counterforce is generated on the pipe section or the ring, against the flow direction of the material produced by the rolling tools, so as to increase the material flow in the axial and / or or radial direction to control.
  • the mandrel outer profile of the first profile mandrel is about as long or at least as long as the pipe section, wherein the first profile mandrel in the kneading step b) is moved in the axial direction together with the tube or moves relative to the kneading tool.
  • the axial inner profile is made by external kneading tools by a material flow is generated in the radial outer profile of the profile mandrel inside.
  • no relative speed between the profile mandrel and the pipe section is present, so that the manufacturing accuracy can be very high.
  • a counterpressure tool is preferably provided, which has a contact section, by means of which an axial counterforce on the pipe section or the ring against the flow direction caused by the rolling tools of the material can be generated, so as to the flow of material in the axial and / or radial To control direction.
  • the counter-pressure tool is preferably formed integrally with the second profile mandrel.
  • a separating device is furthermore preferably provided for separating individual rings from the pipe section.
  • This may be a separate device, for example, a turning tool or milling tool, grinding tool, saw, etc. for radial parting of the individual tubes.
  • the separating device can be arranged in front of the rolling device in order to supply the rolling device in this way individual, profiled only on the inner circumference rings.
  • the separating device may also be arranged on or after the rolling device in order to separate one ring from the pipe section, which is finished profiled both on the inner circumference and on the outer circumference.
