Definitions

  • the present invention relates to a profile rolling machine with two at least approximately parallel roller spindles, as in the preamble of the independent claim 1 is defined.
  • Profile rolling machines are used to form the outer surface rotationally symmetrical workpieces and are e.g. for rolling of threads, screw profiles, gears, knurls and Cords and used for smooth rolling.
  • Known profile rolling machines of the type of interest here include two at least approximately parallel rolling spindles with one each Rolling head for processing an arranged between the rolling heads Workpiece and set to thread rolling either the so-called piercing process, the continuous process or the combined procedure.
  • the grinded on the rolling heads Profile the same pitch angle as that Workpiece.
  • the workpiece remains during the rolling process axially calm; it is therefore also possible to to roll a bunch. This procedure is very precise and therefore for the production of precision threads of all kinds well suited.
  • the rolling heads In the continuous process, the rolling heads have the circumference slope-free grooves, the cross-sectional shape of which is to be rolled Profile corresponds.
  • the rolling spindles with the rolling heads are swung into the flank angle of the workpiece, so that during the rolling process the workpiece one full turn axially.
  • the combined procedure is a connection between and continuous process.
  • the rolling heads have one Pitch angle that is smaller than that of the Workpiece.
  • the resulting angular deviation becomes compensated by swiveling the roller spindles. This will ensures that the workpiece receives an axial feed, which is however smaller than in the normal continuous process.
  • the force frame comprises two yoke plates and four die Yoke plates connecting, each arranged in a tie rod Tie rod.
  • the two yoke plates are on a machine bed firmly attached.
  • One of the two rolling spindles is carried directly from the first yoke plate, while the the other is mounted on a sled which is one of the four Tie rod tubes is guided.
  • Using one on the second Yoke plate attached hydraulic cylinder can the on Slidable roller spindle pushed towards the other become.
  • This profile rolling machine has the disadvantage that the Rolling forces occurring during the machining of a workpiece the two yoke plates of the power frame by one can push a small distance apart and also the machine bed exposed to rolling forces via the yoke plates is.
  • the machine bed can therefore not, among other things, as precise measurement basis for determining the positions of the Roll heads for any compensatory position adjustments one of the rolling heads by means of the hydraulic cylinder be used.
  • the essence of the invention is that in a profile rolling machine with two at least roughly parallel Rolling spindles, each with a rolling head for machining a Have workpiece, and means for poking one of the Rolling spindles towards the other, a force frame on a machine bed can be moved in the direction of the roll spindle is arranged that on this essentially none Impact and rolling forces are transmitted.
  • the power frame comprises two yoke plates and at least two the yoke plates connecting tie rods, each arranged in a tie rod tube.
  • the means for pushing one of the rolling spindles in The direction of the others are partly on one of the yoke plates attached or supported.
  • the force frame is preferably fixed at exactly one point connected to the machine bed. That is the way Force frame anchored on the machine bed, but still Movable in the direction of the roll spindle.
  • roller spindle or both roller spindles are advantageous carried by a sled on the machine bed is supported and guided. Because of the stability of the machine bed becomes the Carriage guided comparatively precisely. This allows unnecessary manufacturing inaccuracies can be avoided.
  • a preferred embodiment variant of the invention Profile rolling machine has one arranged on the machine bed Length measuring device with which the position of the or the sled is measurable with respect to the machine bed is, and advantageously a controller that the means to push one of the rolling spindles towards the other in function of the measurement results of the length measuring device controls so that any elongation of the Force frame is compensated.
  • the effects of rolling forces on the positions of the rolling heads can on this Way completely neutralized and manufacturing inaccuracies be avoided.
  • the force frame is preferably prestressed in such a way that the tie rods under tension and the tie rods under pressure stand. Relieve the load when machining a workpiece occurring rolling forces the tie rod tubes and stress the Tie rod.
  • the prestressing force should be greater than that maximum rolling forces so that the yoke plates at no time lift off the tie rods. Thanks to this bias can the linear expansion caused by the rolling forces of the power frame can be significantly reduced. Also done the release of the rolling heads from the workpiece when moving back the roller spindle or spindles faster than with not pre-tensioned power frame.
  • An inventive profile rolling machine includes one a frame 7 assembled, torsionally rigid, cast Machine bed 3, on the four prestressed guide rails 31-34 are screwed for two slides 4, 40.
  • the two Sledges 4, 40 are supported by three feet 41-43 or 441-443 on the guide rails 31-34, are along this slidable and carry over roller spindle bearings 13 or 14 a roller spindle 1 or 10.
  • the roller spindles 1, 10 each have one for machining a workpiece Roll head 11 or 12 with a suitable profile. To the The workpiece is used to hold the workpiece, not shown Machine bed 3 arranged workpiece holder.
  • the machine bed 3 also carries a power frame 2 with two yoke plates 21, 22 and two yoke plates 21, 22 connecting, each arranged in a tie rod 25, 26 Tie rods 23, 24.
  • the force frame 2 is prestressed inwards, the tie rods 23, 24 under tension and the tie rods 25, 26 are under pressure, and over the tie rod 24 and the tie rod tube 26 only by means of screws 27 one place firmly connected to the machine bed 3.
  • the force frame 2 is opposite the machine bed 3 in the tie rod longitudinal direction, that of the carriage displacement direction and thus corresponds to the direction of the roller spindle, in principle movable except for this one point.
  • the two Ends of the tie rod tube 26 are also each on one Machine bed 3 attached storage 6 and 60 guided and have a compared to the middle part of the tie rod 26 smaller diameters.
  • the force frame 2 is arranged on the machine bed 3, that the two tie rods 25, 26 leave space for loading the workpiece machining area with workpieces both from the front and from above or the attachment of horizontal and vertical loading devices.
  • a hydraulic cylinder is on the yoke plate 22 5 attached with a cylinder piston 50.
  • the cylinder piston 50 is fixedly connected to the slide 4 and pushes it away from the yoke plate 22 or pulls it him towards this, depending on whether the hydraulic cylinder 5 Hydraulic oil is supplied or removed.
  • the sledge 4 is fixed to the yoke plate 21 via a spacer 44 connected.
  • the hydraulic cylinder 5 is in a drive block 8 arranged hydraulic unit operated, the one regulated high pressure / low pressure internal gear pump 81, Pressure relief valves, fans, a thermostat, has a bypass cooler and a bypass pump 82.
  • the drive block 8 is also a continuously variable Drive for the two roller spindles 1, 10 arranged, with belts 83, 84 and shafts 85-88 for power transmission to serve. Articulated shafts are not shown in FIG. 1 between the roller spindle 1 and the shaft 86 and the roller spindle 10 and the shaft 88. These enable a lateral Move as well as for the continuous process Swiveling the roller spindles 1, 10.
  • the control of the profile rolling machine is in a control cabinet 9 arranged and includes with integrated air conditioner a control with amplifier for the infinitely variable Drive and the hydraulic unit as well as a programmable logic controller Control system for a safety compliant
  • the course of the rolling process ensures and has enough Capacity for a possible integration of the profile rolling machine in an automatic manufacturing process.
  • the profile roll machine is not operated via a shown control panel.
  • the rolling spindles 1 and 10 instead of a single, infinitely variable drive driven in a different way via belts can be e.g. with two electronically controlled AC servo motors.
