Definitions

  • the invention relates to horizontal extrusion presses with axially displaceable pick-up holder and runner in the press frame between the lower, weight-absorbing and upper, holding-down guides.
  • the guides - as usual today - as x-guides, i.e. with guide surfaces aligned with the main axis of the press, thermal expansion in the guides can be compensated for.
  • the arrangement of at least three sensors is known (DE-OS 23 04 326), which are arranged on the front side of the transducer distributed around its axis and the position of the end face relative to one perpendicular to the axis Show the reference level to the press.
  • angular deviations can be determined, but not transverse deviations between the transducer and the pressing tools, as can be caused, for example, by temperature differences on the receptacle holder.
  • the requirement of also being able to detect and correct transverse deviations between the transducer and the pressing tools was the aim of the solution according to DE-OS 28 50 576 and DE-OS 30 20 156, according to which a coherent beam of electromagnetic oscillations between a transmitter and one receiver offset parallel to the press axis and by a second and possibly third receiver with a central one Beam passage opening extends, two of the receivers being connected at a distance to the transducer or transducer holder and the transmitter and, if appropriate, the further receiver to the components of the overall system which are to be brought into alignment and to be held.
  • This solution has not proven itself under operating conditions, since it has proven to be susceptible to faults and a hindrance and therefore does not justify the high construction costs.
  • the object to be achieved by the invention is accordingly to detect and, depending on this, correct angular and transverse deviations from the aligned position of the transducer relative to the pressing tools with the rough conditions (high mechanical and thermal loads and heavy contamination) of the extrusion operation have grown.
  • the object of the invention is achieved using sensors known per se in that According to the invention, the measuring sensors on the upper, holding-down guide shoes to the sensor holder and to the spar between the guide shoes and the sensor holder or spar carrying them measure and display the distance of the guide shoes to the sensor holder or spar parallel to the pressure elements or the pressure elements themselves are designed as sensors .
  • the invention can be implemented with known, tried and tested elements, the sensors being able to be accommodated in a protected location without taking up any special space, which is therefore otherwise available.
  • the sensors can, for example, be designed as inductive displacement sensors and be arranged parallel to spring assemblies, which press the guide shoes off the arms of the pick-up holder and the arms of the running arm for contacting the upper guides.
  • spring assemblies which press the guide shoes off the arms of the pick-up holder and the arms of the running arm for contacting the upper guides.
  • Another possibility is the design of the pressure elements acting on the guide shoes as piston-cylinder units, in which case the pistons form the travel sensors or are connected directly to them.
  • the measuring sensors As changes in operating conditions, e.g. that does not suddenly set the temperature of the components, it is often sufficient to assign the measuring sensors to the measuring station on the press control station, which indicate any deviations occurring, so that the operating personnel can recognize the extent of the deviations and, if necessary, make the corrections.
  • the actuators of the guide shoes with a motor drive, for the control of which signals are connected to a control computer evaluating the measured values of the measuring sensors.
  • the lying extrusion press shown as an embodiment consists of a foundation frame 1 on which a cylinder spar 2 and a counter spar 3 rest, which are connected to one another by prestressed anchors 4.
  • the anchors 4 are made of tension members, consisting of a plurality of sheet metal plates 5, which rest with hammer heads 6 on the outside of the cylinder spar 2 and on the counter beam 3, and are formed of sheet metal plates 5, on the inside of the cylinder beam 2 and on the counter beam 3, that is to say rectangular pressure pieces 7 located between them .
  • Wedge strips 8 and slideways 9, which form lower and upper guides 10 and 11, which form planes aligned with the press axis 12, are placed on the pressure pieces 7.
  • piston and cylinder units 15 are provided for displacing the transducer holder 13 above and below and are connected to the transducer holder 13 by piston rods 16, while the spar 14 of a plunger arranged in the cylinder 17 in the pressing direction and by return pistons arranged in cylinders 18 arranged on both sides of the cylinder 17, which are connected by their piston rods 19 to the barrel member 14.
  • the pick-up holder 13 carries a pick-up 20 and the running beam 14 a press die 21.
  • a die is supported on the counter beam 3 via a die holder 22.
  • the embodiment is a direct extrusion press. It goes without saying that the invention also relates to indirect extrusion presses in which the die is supported by a die stamp. The invention also relates to direct or indirect hollow extrusion presses in which a mandrel forming the extrusion cavity is arranged in the press die 21 or in the take-up closure piece which takes the place of a press die and is displaceable in a bore of the press die 21 or the closure piece.
  • the pick-up holder 13 is provided with arms 23 and the walking bar 14 with arms 24, which carry lower guide shoes 25 and upper guide shoes 26 with which they rest on or rest on the lower guides 10 or the upper guides 11.
  • the lower guide shoes 25 are connected to the arms 23 of the transducer holder 13 and the arms 24 of the runner 14 by actuators.
  • threaded spindles 27 are provided as actuators, which are rotatable in threaded bores 28 located perpendicular to the guides 10 in the end pieces 23a to the lower arms 23 and 24a to the lower arms 24.
  • the threaded spindles 27 are provided with end pins 27a with which they are rotatably seated in bores 29 of the guide shoes 25.
  • Anchor bolts 30 are screwed into the guide shoes 25 and penetrate the hollow threaded spindles 27, nuts 31 at the ends of the anchor bolts 30 securing the cohesion of the guide shoes 25 with the threaded spindles 27. With 32 rotation locks are designated, which an unwanted rotation of the threaded spindles 27 after Prevent setting.
  • the upper guide shoes 26, which have the task of holding down the pick-up holder 13 or the spar 14 and thus securing their position, are resiliently connected to the arms 23 of the pick-up holder 13 or the arms 24 of the spool 14.
  • plate spring assemblies 33 are arranged between the guide shoes 26 and the threaded spindles 34.
  • these threaded spindles 34 are also rotatable in threaded bores 35 in the end pieces 23a of the upper arms 23 and 24a of the upper arms 24.
  • the threaded spindles 34 are set in such a way that the plate spring assemblies 33 have a sufficient contact pressure of the guide shoes 26 on the upper guides 11 maintained.
  • Nuts 37 placed on the anchor bolts 36 to the guide shoes 26 leave sufficient play so that the guide shoes 26 can always keep contact with the guides 11.
  • Tilting, asymmetrical thermal expansion and the like disturbances lead to a change in the distance between the end pieces 23a and 24a of the upper arms 23 and 24 of the pick-up holder 13 and the runner 14 to the upper guides 11 and under the force of the plate spring assemblies 33, the guide shoes settle 26 correspondingly from the end pieces 23a of the upper arms 23 or the end pieces 24a of the upper arms 24.
  • the end pieces 23a and 24a of the upper arms 23 and 24 are therefore provided with sensors 38.
  • These sensors 38 are inserted in bores 39 which are arranged axially parallel to the threaded bores 35 for receiving the threaded spindles 34. Nuts 38a fix the sensors 38 in the holes 39.
  • In the sensors 38 are axially movable probes 40, which follow the guide shoes 26 under spring pressure and inductively detect their changes in position. Lines 41 connect the sensors 38 to their associated indicators on the press control station.
  • sensors 42 with feelers 43 can be provided, which via pressure bolts 44 the distance of the Measure and display end pieces 23a and 24a and thus the position of the transducer holder 13 and the running bar 14 relative to the lower guides 10.
  • the end pieces 23a and 24a are for receiving the measuring sensors 42 with stylus pins 43 and pressure bolts 44 provided with stepped bores 45, in the sections of smaller diameter, the pressure bolts 44 are guided, while the sections of larger diameter are closed by deck 46, which carry the sensors 42 and support compression springs 47, which hold the pressure bolts 44 in contact with the lower guides 10 .
  • the sensors 42 with their display of the initial position of the pickup holder 13 and the running bar 14 to the lower guides 10 and the changes in these initial positions, for example due to wear on the guide shoes 25, provide additional information for assessing the measurement results on the sensors 38, which is why the sensors 42 also have measured value indicators are assigned to the press on the control station and are supplied to the control computer as inputs when controlling the actuators.
  • FIGS. 5 and 6 show the end pieces 23a of the arms 23 of the receptacle holder 13.
  • the running bar 14, which already has a guide in the cylinder 17 via the plunger connected to it, is therefore provided with only one guide shoe in each end piece 24a of the arms 24, which can be arranged in the middle of the end pieces 24a.
  • a variant of the illustrated embodiment is shown in dotted lines for one of the actuators in FIG.
  • the worm wheel 48 of a worm gear 49 is connected to it in a rotationally fixed but axially movable manner. The adjustment thus takes place via the motor 50 and the worm 51 in the worm gear 49 fastened to the end piece 23a.
  • the motors 50 can be controlled manually from the control station or by control signals from a control computer evaluating the measured values of the sensors.
