Definitions

  • the present invention relates to a method according to the preamble of claim 1, a device for its implementation, and its use, see for example the GB-A-1 324 090 ,
  • an axial profiling of a thin-walled, cylindrical hollow part can be done for example by means of cold rolling.
  • procedures are off US 5,355,706 in which profile rollers are radially brought as tools on a circular path on the workpiece in striking engagement and produce by axial feed of the workpiece relative to the profile rollers, the desired profiling using a toothed mandrel tool inside and outside.
  • arcuate longitudinal contours are generated, which depending on the size of the web diameter have a larger or smaller radius, but are always present.
  • a disadvantage of this cold forming process by means of profile rollers is that the teeth on a cylindrical workpiece with shoulder can not be executed close to this shoulder zoom.
  • the object of the present invention was to find a method and an apparatus which a accurate profiling of thin-walled, cylindrical hollow bodies with a defined profile geometry, even close to a shoulder area zoom.
  • a cold-forming profiling of cylindrical, thin-walled hollow parts is carried out, with substantially parallel to the longitudinal axis of the hollow part extending profiles, wherein radially to the longitudinal axis of the hollow part on the hollow part from the outside at least one profiling tool is suddenly hammered acting, wherein the profiling tool is brought in each case in an essentially vertical direction oscillating on the surface of the hollow part to act. Furthermore, the profiling tool is displaced axially relative to the hollow part at a constant radial infeed depth until the desired profile length has been reached.
  • the profile can be completely generated in its entire length, wherein the entire forming work is divided into a plurality of individual steps.
  • the forming forces of each individual step can be kept relatively small. This leads to a high accuracy of the profile produced, both as an inner or outer profile, as well as an excellent Profilausformung.
  • the method can be relatively small profile radii are generated, which significantly increases the load-bearing flank share compared to identical profile dimensions.
  • the profiling tool can be positioned close to a possible shoulder of the hollow part thanks to substantially vertical oscillating movement with respect to the surface of the hollow part, thus profiling up to close to this shoulder. This means that the profiling tool performs virtually no movement in the axial direction and thus also does not require any free movement space in the axial direction in the machining area of the hollow part.
  • the profiling tool is delivered radially to the longitudinal axis of the hollow part up to a predefined feed depth for axial displacement. Because the resp. the profiling tools are arranged radially before the actual machining operation in a remote position from the hollow part, the hollow part can be arranged with sufficient free space in the processing device resp. be connected with a workpiece holder.
  • a change of direction of the axial displacement between profiling tool and hollow part is performed at least once, in particular after reaching the desired profile length back to the original relative starting position between profiling tool and hollow part. This allows very high demands on the accuracy and surface quality of the profiling can be met. It is even conceivable a multiple axially parallel back and forth move the hollow part with respect to the profiling tool to achieve the desired surface quality.
  • the profiling tool For example, respectively after completion of the axial relative displacement resp. Move the profiling tool radially out of the profile of the hollow part.
  • the finished molded hollow part can be easily removed from the processing device and insert a new blank.
  • a defined profiling such as a toothing with a defined pitch, can be generated.
  • the oscillating stroke movement of the profiling tools is chosen to be greater than the maximum radial insertion depth of the profiling tools into the hollow part.
  • the hollow part for example, intermittently, synchronized with the oscillating stroke movement rotates about its axis, for example, in each case by the pitch of the profiling to be generated.
  • the profiling tool may be operated at over 1000 beats per minute, for example at over 1500 beats per minute. This allows very high production rates to be achieved, which is of great advantage, especially for mass production in the automotive industry.
  • the hollow part is placed on a profiled mandrel for machining, which is displaceable relative to the profiling tool along the longitudinal axis.
  • This will be the outdoor as well as the Inner profile of the hollow body made according to the specifications of the shape quickly and very accurate.
  • the profiling of the mandrel ranges from its free end to a radially outwardly projecting shoulder and it is placed a hollow part, which is pot-shaped and also a shoulder resp. has an edge.
  • Such hollow parts are used for example in gearbox application, as for the transmission of rotation and torque in automatic transmissions.
  • the profiles must be executed as exact internal and external teeth to close to the outwardly projecting edge of the hollow part resp. be made.
  • the profiling tool for the first process section in the region of the shoulder of the mandrel resp. brought radially to the action in the region of the edge of the hollow part and in the second process section the mandrel is axially displaced away from the profiling tool.
  • either the profiling tool or the hollow part can be moved in the machine to produce the axial relative movement between the hollow part and profiling tool. This movement is carried out, for example, in such a length until the profiling tool no longer comes to act on the hollow part. This movement is referred to as a pulling movement, since the profiling tool moves practically after the piercing process to the base of the profile pulling relative to the hollow part and thus the entire length of the profiling is generated.
  • the profiling tool is first in the region of the free end of the hollow part resp. the mandrel radially delivered and then the mandrel resp. the hollow part axially with respect to the profiling tool to the shoulder resp. moved to the edge, for example, until the profiling tool close to the shoulder of the mandrel resp. the edge of the hollow part is in action.
  • the relative movement between Profiltechnikstechnikmaschine and hollow part in the machine can be accomplished by axial displacement of the hollow part. This movement is referred to as an abutting movement, since the profiling tool primarily shapes and completes the profile against the edge of the hollow part.
  • the tool can be delivered outside the free end to the predefined feed depth and only then brought to the hollow part to act.
  • at least two profiling tools arranged radially opposite one another are used which, for example, are driven synchronized with one another with respect to their radial infeed and their oscillatory movement. This ensures optimal force distribution and introduction.
  • the profiling tool is delivered radially in relation to the workpiece continuously or in discrete, adjustable steps until the final profile depth of the hollow part is reached.
  • the device for carrying out the claimed method at least one operatively connected to an eccentric tool holder for a profiling tool, a relative to the tool holder along its longitudinal axis slidably formed mandrel resp.

  • the calibration zone first engages in the surface of the hollow body, since this zone is closest to the surface of the hollow body in the machining direction of the stamp. After the penetration of the calibration zone, the remainder of the working surface of the stamp can penetrate into the surface, in particular when the hollow body is pulled, and a first pre-deformation of the hollow body can take place.
  • the calibration zone In the second stage of the procedure, when the punch is moved axially with respect to the hollow body with constant radial infeed, the calibration zone then only needs to carry out the final deformation of the profile.
  • the length of the stamp resp. the length of the working profile longer than the length of the profile to be generated in the hollow body.
