Definitions

  • the invention relates to an operating element for a press and a press with such a control element.
  • a handwheel is used as a control element. With such a hand wheel, the operator can position the plunger of the press very accurately on the workpiece, for example on a metal sheet.
  • the handwheel allows the operator to move the ram in minimal steps while adjusting the tool and positioning it very precisely. Furthermore, he can also undo or correct the plunger movement to ensure optimum setup of the particular new tool. This makes it possible for the operator to incorporate new tools in a simple manner.
  • the invention has for its object to provide an improved control element for a press, in particular, the precision and the speed of setting up new press tools to be increased.
  • the object is achieved by an operating element for a press, by means of which an upper tool of the press can be positioned on or in a workpiece to be machined, wherein the operating element has at least one actuator, by means of which a counter-torque or opposing force can be generated on an operating hand of an operator is, wherein the counter-torque or the counter force is related to a current force by means of which the upper tool acts on the workpiece.
  • control element is given the ability to provide sensory feedback to the operator's hand by mapping the said force of the upper tool to a counter-moment or to a counter-force of the operating element.
  • the setup process of the new tool has become "tangible”. This error is reduced in particular by misinterpretation, since, for example, the reading of forces from the machine panel omitted.
  • the operator can react immediately to the counter-torque or the counter-force and observe the work result.
  • the actuator comprises a stepper motor.
  • Stepper motors for generating the counter-torque or the opposing force are now available in small versions, so that they can be conveniently accommodated in a compact hand control for a press.
  • the actuator may further comprise a so-called rumble motor, by means of which at least one vibration pattern can be generated.
  • Such rumble motors are known, for example, in mobile phones, wherein instead of a ringing tone or in addition to this, the mobile phone is vibrated to indicate to the operator an incoming call or other data.
  • Different vibration patterns can here indicate different events to the user of the mobile phone.
  • the vibration pattern (s) may be tuned to the current ram force so that the vibration pattern is a measure of said upper tool force.
  • the vibration pattern is therefore related to the actual ram force.
  • the actuator may comprise a spring whose tension is related to the force of the upper tool.
  • the spring force acts as a counter-torque or counterforce on the operator's hand.
  • control element is designed as a handwheel.
  • the invention further leads to a press, comprising at least one operating element as mentioned above and a control unit connected to the control element for determining the current force with which the upper tool acts on the workpiece, and for controlling the operating element with a control command based on the determined current Force of the upper tool, so that the driven with the control command Actuator generates the counter-torque or the counterforce on the operator's hand.
  • FIG. 1 shows a press 1 according to the invention, comprising an upper tool 3, driven by a press ram, not shown in detail, and a lower tool. 5
  • a sheet workpiece 7 is introduced, which is to be pressed by means of the upper tool 3 in a desired shape.
  • a handwheel 11 As a control available.
  • This handwheel 11 may comprise, for example, a rotary knob 15 by means of which the press ram is movable in very small steps.
  • a pressing force is exerted on this sheet-metal workpiece 7.
  • This pressing force is determined by means of a control unit 9.
  • the control unit 9 forms from this determined current pressing force a control command for controlling the handwheel 11.
  • the handwheel 11 comprises an actuator 13, for example a stepper motor, by means of which a counter-torque or a counterforce can be generated on an operating hand of the press operator.
  • This counter-moment or this counterforce on the operator's hand of the press operator is related to the current press force of the upper tool. The operator thus receives an immediate sensory feedback about this currently occurring force.
  • FIG. 2 shows a schematic sectional view through a press with a control element according to the invention.
  • the press 1 comprises a plunger cylinder 15 for driving a press ram 17.
  • An upper tool 3 for forming a sheet-metal workpiece 7 is connected to the press ram 17.
  • the sheet metal workpiece 7 is mounted on a sheet metal retainer 19 which is movable relative to a lower tool 5.
  • the lower tool 5 is connected to a press table.
  • control unit 9 and the hand wheel 11 with the actuator 13 correspond to the corresponding elements in the FIG. 1 ,
