Definitions

  • the invention relates to a press or punching machine with a frame that includes a press table and a drive unit supported by columns, as well as with one from the drive unit to a reciprocating motion drivable plunger, and with an adjusting device to adjust the ram reversal position during the operation of the press or punching machine, a sensor being assigned to the adjusting device is to accommodate one of the plunger positions Measured variable for adjusting the ram reversal position depending on the measured variable.
  • EP 0 367 035 B1 proposes the immersion depth of the plunger can no longer be regulated directly, but indirectly via the one that occurs in the tool Print. For this purpose it is proposed to use the sensor as Train the pressure transducer, either on the upper tool or is arranged on the lower tool. The one when moving together from upper tool and lower tool to the Pressure transducers acting here are a measure for the immersion depth.
  • the object of the present invention is to provide a press or to further develop a stamping press of the generic type in such a way that in a structurally simple way reliable measured variable for adjusting the tappet reversal position can be provided.
  • This task is done with a press or punching machine of the type mentioned at the outset in accordance with the invention, that the press or punching machine has at least two Has sensor, each on a column of the Frame are arranged.
  • the solution according to the invention is particularly noteworthy by their constructive simplicity. It has namely shown that a reliable parameter for Adjustment of the tappet reversal position through the insert be ensured by at least two sensors can, each arranged on a column of the frame are. Separate sensors for each use upcoming tools can thus be omitted. You can also through the sensors arranged on the columns Asymmetries when acquiring the measured variables reliably can be prevented, especially in cases where the tools asymmetrical with a compressive force be charged. This is the case, for example Case when modular composite tools are used come into which several stations are integrated, in which the workpiece is processed one after the other, for example cut, bent, drawn and embossed becomes. Here, eccentric deformation forces occur so that those in the tool Forces depending on the position and thus to regulate the The tappet reversal position can only be used to a limited extent.
  • the sensor has a control signal provide that of the one working in the respective pillar Press force corresponds.
  • the one in the respective pillar acting press force is therefore a measure of regulation represents the tappet reversal position in the usual way by means of piezo sensors, strain gauges or other force transducer determined become.
  • the pressing forces occurring in the individual columns can in an electronic signal processing unit combined to a total pressing force which in turn are a measure of the regulation of the Plunger reverse position.
  • the press or punching machine comprises an electronic comparison unit with the Help the measured variable provided by the sensors can be compared with a setpoint that preferably via a programming input of the comparison unit can be specified. Does that give way by means of Sensor determines the actual value from the specifiable setpoint beyond a predetermined tolerance, so the ram reversal position is corrected accordingly.
  • the adjustment device with the help of which the plunger position, especially the bottom dead center position of the ram, while the ongoing operation of the press or punching machine can be readjusted.
  • the measuring sensor is on at least two diagonally opposite one another Columns of the frame are arranged.
  • the diagonal arrangement the sensor on the frame of the press or Punching machines may be similar to those that occur on the frame Asymmetries of the pressing force, so that the electronic signal processing from the sensors provided electrical signals simplified becomes.
  • a particularly reliable measurement variable for adjustment the tappet reversal position can be obtained that the frame of the press or punching machine four Includes columns on each of which at least one sensor is arranged. All pillars of the frame are thus with regard to the pressing force occurring monitors, the measuring signals occurring in the Signal processing unit for a manipulated variable for the Adjustment of the tappet reversal position can be processed.
  • the control of the tappet reversal position can be done in In the form of a programmable logic controller (PLC), or also by means of a personal computer or by combining these two controls.
  • PLC programmable logic controller
  • the press or punch press is operated here preferably via a control panel with a display device and enter keys.
  • the input and Data output via a personal computer.
  • the measuring sensor each on one of the tool installation spaces of the press or punching machine facing side of the columns are. It has been shown that such internal arrangement of the sensors a mechanical Protection of the sensor ensured, so that additional Housing for the sensor can be omitted.
  • the senor not only are coupled to the adjusting device, but additionally with an overload protection of the press or Punching machines, with the help of which the press or punching machine in the event of a malfunction due to an overload can be turned off.
  • Such an embodiment is characterized by a particularly constructive simple design based on the sensor both a signal for the emergency stop of the press or punching machine provide when a fault occurs, as also a measured variable for adjusting the tappet reversal position during operation of the press or Punching machines.
  • FIG. 10 In the drawing is a schematic Fast punch machine shown, the total with the Reference number 10 is occupied. It includes a frame-like Frame 12 with a press table 14 and overall four essentially in the corner points of a rectangle arranged columns 16 which a drive unit 18th contribute to driving one in the vertical direction and forth movable plunger 20.
  • the drive unit comprises 18 an eccentric shaft 22 which 24 is rotatably held on the frame 12 and by means of a the drawing, not shown, known per se Drive motor can be driven to rotate.
  • two connecting rods 26, 27 are rotatable held.
  • the connecting rods 26, 27 are at their free ends via a to adjust the reverse position of the Tappet provided adjusting device 29 on the tappet 20 held on each in the area of the columns 16 a guide column 31 is fixed. Every pillar is at the end above and below one through the columns 16 and the plunger 20 and the press table 14 limited tool space 33 a backlash preloaded roller bearing 35 associated with a guide bush, so that the plunger 20 by means of the guide columns 31 and the roller bearing 35 in the vertical direction is exactly guided.
  • oil cooling circuit 37 provided with one in the Drawing, not shown, oil tank in the Press table 14 is integrated.
  • the plunger 20 is on the connecting rods 26 and 27 by means of the Eccentric shaft 22 can be driven to move back and forth.
  • the drive unit 18 includes one above the eccentric shaft 22 arranged and with this over a Connecting rod 39 coupled balancing mass 41, which is vertical aligned guide rods 43 is guided.
  • the signal processing unit 51 includes an electronic display device 53 and a keypad 54 for entering control data and serves to control the automatic punching machine 10 including the adjusting device 29, and in addition also to control a known, in the Drawing, not shown, feed apparatus, with the workpieces to be machined in the tool installation space 23 can be supplied.
  • the sensors 49 register the in the respective Pillar 16 occurring press and stand over the signal processing unit 51 not only with the adjustment device 29 in electrical connection, but additionally also with a known and therefore overload protection not shown in the drawing, if an overload occurs in at least one the columns 16 switches off the automatic punching machine 10.
