Definitions

  • the invention relates to a spinning machine according to the preamble of claim 1.
  • Pressing machines and associated roll holders are known and have long been used for the cold forming of rotationally symmetrical workpieces.
  • the roll holder is used in particular to quickly convert the spinning machine from one spinning roller to another spinning roller.
  • several roll holders are usually arranged in a magazine and can optionally be connected to the support arrangement, the selection and connection and separation of the roll holder as well as the pressing process itself taking place automatically under the control of a control program.
  • a common method for the generation of control data for the control program is the so-called playback method, in which the spinning machine is first manually operated by an operator and at the same time the respective operating steps and the spinning roller positions thus generated are recorded electronically and recorded as data. On the basis of this recorded data, the same workflow is then repeated as often as desired exactly and with increased working speed under the control of the control program, the spinning roller gradually moving to the stored positions.
  • EP 0 125 720 B1 discloses a spinning machine provided with a corresponding force limiting device.
  • the roll holder is rigid, but a spring unit is arranged between the upper support of the support arrangement and the drive device for the upper support.
  • the force exerted by the pressure roller on the roller holder and on the upper support on its drive device is detected by means of a sensor on the basis of the degree of compression of the spring unit, the force detected essentially corresponding to the force exerted by the pressure roller on the workpiece.
  • the measured force values are fed to a control unit and, under the control of the control program, the slide carrying the roll holder is withdrawn by means of its drive unit in accordance with the measured values when a predeterminable degree of compression of the spring unit is exceeded. or when the pressure drops below a predefinable degree of compression.
  • the force that can be exerted on the workpiece by the spinning roller can be limited in a simple manner to harmless values by setting a corresponding pressure of the pressure medium. Furthermore, by using the piston-cylinder arrangement, the force acting on the piston can be kept practically constant over the entire stroke, ie a largely linear characteristic is achieved. Since the moving masses are very small, a very high speed of reaction is ensured, which allows a high working speed. In addition, no control loop is required here, which excludes swinging or rocking and what makes sensors and other additional control and regulating devices superfluous.
  • the invention is also suitable for retrofitting existing spinning machines, because only an exchange of the roll holder is required.
  • a pressure medium source for example for compressed air or hydraulic fluid, is generally present anyway, so that, apart from a pressure control unit that may still be required, this does not involve any great additional outlay.
  • the exemplary embodiment of a roll holder 1 shown here essentially consists of a fixed holder part 2, which can be connected to a support arrangement (not shown here) of a spinning machine, and a holder part 3 that is displaceable relative to the latter.
  • the fixed holder part 2 At its end facing the support arrangement, ie in the 1 right, the fixed holder part 2 is formed with a cylinder 20, which by means of a cylinder base 21 for the support arrangement is closed.
  • the cylinder base 21 is releasably connected here with the interposition of a sealing ring 26 'to the remaining part of the fixed holder part 2 and has a central pressure medium connection 22, which has the shape of a stepped bore, for supplying and removing a pressure medium.
  • Above and below this cylinder 20 there are connecting flanges 23 with bores 23 ', by means of which a releasable connection of the roll holder 1 to the support arrangement can take place.
  • the fixed holder part 2 In its averted from the support arrangement, i.e. in the left part of the drawing, the fixed holder part 2 carries a guide body 24 which extends in the longitudinal direction of the roll holder 1.
  • the thrust piece 34 On its inner, i.e. in the right end of FIG. 1, the thrust piece 34 is connected to the end face 31 of a piston 30, which is displaceably guided in the cylinder 20 with a seal by an intermediate sealing ring 26.
  • the thrust piece 34 On its outer, i.e. in the left end of the drawing, the thrust piece 34 carries a pressure roller bearing body 32, on which a pressure roller 10 is rotatably mounted about an axis of rotation 10 '.
  • the connection between the thrust piece 34 and the pressure roller bearing body 32 takes place here by means of a screw 33 running in the direction of the axis of rotation 10 ′, whereby a simple exchange of the pressure roller bearing body 32 with the pressure roller 10 is made possible.
  • the piston 30 When the interior of the cylinder 20 is loaded with the pressure medium through the pressure medium connection 22, the piston 30 is preloaded in the direction of extension with a force which is dependent on the pressure of the pressure medium.
  • the stroke of the piston 30 and thus also the thrust piece 34 and the pressure roller 10 is limited by a stop 25 which is arranged above the thrust piece 34 and forms part of the fixed holder part 2.
  • a stop cam 35 On the top of the thrust piece 34, a stop cam 35 is attached, which in the basic position of the roller holder 1 shown in FIG. 1 bears against the stop 25.
  • the stop 25 is designed to be adjustable, with a stop support 25 ′ being provided here for this purpose, which runs parallel to the thrust piece 34 and on which the stop 25 can be displaced after loosening a screw and fixed again by tightening the screw.
  • the roll holder 1 is now shown in an operating position in which it is connected to a support arrangement 4, which is only hinted at here, and in which the pressure roller 10 rests on a workpiece 11, which in turn together with a shaping tool , rotationally symmetrical chuck 12 rotates about a spinning machine spindle axis, not shown here.
  • the spindle axis usually runs at an angle between approximately 20 and 90 ° to the axis of rotation 10 ′ of the spinning roller 10, which in turn is set in rotation by the rotating chuck 12 and workpiece 11.
  • the support arrangement 4 has an integrated pressure medium line 42, so that when the roll holder 1 is mounted on the support arrangement 4, a connection to a supply device for supplying and discharging the pressure medium is automatically established.
  • the support arrangement 4 which generally comprises a sub-support and a top support arranged transversely thereto, is moved by means of adjusting devices which can be controlled by the control unit in such a way that the pressure roller 10 performs the desired movement along the workpiece 11 and Feed 12 executes.
