Definitions

  • the invention relates to a cutting and forming machine with a in a moving machine part / e.g. the upper part of the tool, the adjusting device for delivering the cutting and shaping tool and with a measuring device for measuring the cutting and forming result, the measuring signals of which are used to adjust an actuator which actuates the adjusting device.
  • a cutting and forming machine of this type has long been manufactured, used and sold by the applicant in his own company. These are usually progressive dies in which strip material is cut and shaped in several steps. Progressive composite tools of this type have an essentially moving and a non-moving machine part. Adjusting devices for adjusting the cutting and forming inserts are located in the moving upper part of the tool. After the strip material has left the forming and cutting area, it is fed to a measuring device for measuring the cutting and forming result. The resulting measurement signals are used to set an actuator of the adjustment device. This adjustment process was previously carried out manually and based on the experience of the operator. To do this, the entire system must be stopped so that the Operator who can operate the adjusting device moved with the upper part of the tool.
  • the invention is therefore based on the object of providing a cutting and shaping machine of the type described in the introduction, in which the adjustment process can be carried out automatically and with the greatest possible precision while the machine is running.
  • the actuator consists of a fixed to a non-moving machine part servomotor
  • the output shaft is coupled to the adjusting device via a gear arranged on the moving machine part
  • the drive-side part on the output shaft of the servomotor rotatably, but in Direction of movement of the moving machine part is arranged displaceably.
  • the gear is designed as a worm gear.
  • the drive-side part of the worm gear can advantageously be designed as a worm which, coaxially with its axis of rotation, has a polygon opening into which a corresponding polygonal output shaft of the servomotor engages.
  • the worm is arranged on the output shaft of the servomotor so that it cannot rotate and move longitudinally, so that it can move together with the gear and the moving machine part.
  • the output-side part of the transmission is designed as a worm wheel, which is arranged in a torsion-proof manner on an actuating shaft and is connected via it to the adjusting device.
  • the transmission is designed as a rack and pinion gear.
  • the servomotor is designed as a stepper motor.
  • the control signals emanating from the control device can be converted into a precise rotary movement for actuating the adjusting device.
  • the adjusting device has a wedge slide that is longitudinally adjustable and non-rotatable on the movable machine part, the wedge surface of which acts on a plunger that can be moved along with the moving machine part and that communicates motion with the cutting or forming tool that is guided in the non-moving machine part .
  • the wedge gate valve is connected to the control shaft of the gearbox via a screw connection.
  • the wedge slide acts directly on the cutting or forming tool, which is also in the moving machine part is arranged.
  • a further preferred embodiment provides that the gear mechanism formed on the moving machine part is designed as a universal joint, the part on the output side of which is fixed to an adjusting shaft of the adjusting device and whose part on the drive side is firmly connected to a telescopic rod.
  • This telescopic rod is non-rotatable and longitudinally displaceable in an output shaft of the servomotor designed as a telescopic rod, which is connected to the servomotor via a further universal joint.
  • FIG. 1 shows a longitudinal section of a partial area of a cutting and forming machine according to the invention with a forming tool arranged in the non-moving machine part
  • FIG. 2 shows a longitudinal section of a partial area of a cutting and forming machine according to the invention with a cutting tool arranged in the moving machine part

  • Fig. 1 is a schematic representation of a cutting and forming machine is shown, which is essentially formed from a movable machine part with a press bar 1 and a non-moving machine part with a cutting plate 14.
  • an adjusting device 11 is provided for feeding the forming tool 13.
  • the forming tool 13 processes a strip material 17, which after leaving the cutting or forming machine is passed through a measuring device 2 for measuring the forming result.
  • the measurement signals are fed into a control device 3 and converted into control signals with which a stepper motor 4 is controlled.
  • This stepping motor 4 is fixedly arranged on the non-moving machine part 14 and has a vertically standing hexagonal output shaft 5.
  • the worm 7 is displaceably arranged on the hexagonal output shaft 5 of the servomotor 4 with a polygon opening introduced coaxially to its axis of rotation.
  • the worm 7 is in engagement with a worm wheel 8, which is connected to an actuating shaft 9.
  • the adjusting shaft 9 is connected to a spindle 15 which is fixed in the longitudinal axis and which is screwed into a wedge slide 10 which is longitudinally adjustable and non-rotatable on the movable machine part 1.
  • the wedge surface of the wedge slide 10 acts in a motion-transmitting manner on the upper side of a plunger 12 which is moved along with the moving machine part 1.
  • the lower end of the plunger 12 is supported by a ball joint 18 in a rocker system which is rotatably supported as a semicircular element in a corresponding semicircular recess.
  • Another ball joint 19 connects the rocker system 20 to the forming tool 13. In this way, upward bends can be carried out.
  • control device 3 determines that the measurement signals coming from the measuring device 2 do not correspond to a predetermined setpoint, then it controls the fixed stepper motor 4, from which a mechanical actuating pulse is transmitted via the hexagonal output shaft 5 to the worm gear 6 which is moved along with the movable machine part becomes.
  • the worm wheel 8 then operates via the adjusting shaft 9, the spindle 15, whereby a longitudinal displacement of the wedge slide 10 is effected. This results in a longitudinal displacement of the ram 12 relative to the moving machine part 1, which is transmitted to the cutting tool 13 via the rocker system 20.
  • FIG. 2 shows a longitudinal section of a partial area of a cutting and forming machine according to the invention with a forming tool 13 arranged in the moving machine part.
  • This forming tool 13 acts on the strip material 17 from top to bottom and consequently produces a downward deformation on the workpiece.

  • all further steps proceed analogously to the description according to FIG. 1.
  • an actuator and an actuating shaft 9 which is connected to a spindle 15 fixed in the longitudinal axis, a longitudinally adjustable and non-rotatable wedge slide 10 on the movable machine part 1 by turning the Spindle, which is in screw connection with the wedge slide, delivered.
  • the wedge surface of the wedge slide 10 acts directly on the forming die 13, which is moved along with the moving machine part.
  • an adjustment process of a cutting and shaping tool of a cutting and shaping machine can be carried out automatically and with great precision while the machine is running.
  • a measuring device is preferably provided behind each cutting or forming station of the cutting and forming machine. In this way, insufficient cutting and forming results can be continuously corrected due to material inequality within a roll of the strip material.

Abstract

Une machine travaillant les métaux par formage et par coupage comprend un dispositif d'ajustage (11) situé dans une partie mobile de la machine, par exemple la partie supérieure de l'outil, qui sert à faire avancer l'outil (13) de formage et de coupe, et un dispositif de mesure (2) du résultat du formage et du coupage dont les signaux de mesure servent à ajuster un organe de régulation (9) qui actionne le dispositif d'ajustage. L'organe de régulation comprend un servomoteur monté fixe sur une partie immobile de la machine dont l'arbre de sortie (5) est couplé, par un engrenage (6) agencé sur la partie mobile de la machine, au dispositif d'ajustage. La partie (7) du dispositif d'ajustage du côté entraînement est montée de manière qu'elle ne puisse pas tourner sur l'arbre de sortie du servomoteur, mais de manière qu'elle puisse se déplacer dans le sens de déplacement de la partie mobile de la machine.
