Definitions

  • the invention relates to a punching machine with a punching tool consisting at least of a punch and a die, the punch being designed as a multiple punch with at least two punching pins.
  • punching machines are already known. They are used for simultaneously punching at least two holes spaced apart, preferably in a sheet. The punching pins are held in a base body so that they can be removed and re-grinded individually or exchanged for another. Accordingly, when working with these punching machines and their punching tools, a punching pattern is created, which is due to the number and shape of the punching pin and the mutual assignment of the punching pins to one another is true.
  • the object of the invention is to develop a punching machine of the type mentioned in such a way that, while the magazine size remains the same, the number of available punching tools is at least doubled and the transition from one punching pin to another of each multiple stamp is possible briefly and simply.
  • the punching machine is designed in accordance with the preamble of claim 1, in accordance with the characterizing part of this claim.
  • all punch pins are in an inactive inactive position, with the exception of one.
  • the punch in its working position can punch the workpiece in a known manner during the working stroke of the punch. If the punching machine works with a program, this program can be run with this punch without any restrictions.
  • due to the preferably provided individual displaceability of the punch pins it is also possible to bring two or more into their working position at the same time and thereby use this punch as a multiple punch, and even different punch patterns are possible.
  • the design of the punch according to the invention also enables an embodiment in which the punch pins not required in each case are in their extended position, but are pushed into the base body to a certain extent when they hit the workpiece and the working stroke of the punch causes no support at their inner end. without punching the workpiece.
  • the punching pins currently required for punching are held in their retracted rest position by means of a device or a suitable device. This locking in the rest position can be coupled with the changing process from one punch to another, so that when a punch is moved from the poof position to the working position, the punch previously in the working position is automatically pushed back into its rest position and subsequently also locked.
  • control element is designed in such a way that this transfer from the working position into the rest position and with respect to the subsequent punching takes place simultaneously or in succession pin from the rest to the working position.
  • the locking can also be brought about by this control element or by the punching pin itself.
  • control element or elements is or are assigned to the inner ends of the punching pins. This enables a particularly simple and reliable training of the control element (s).
  • the relevant inner punch pin ends run flush with the inner end of the or their bore for the displaceable mounting and that the control members or their assigned or assigned bores on Cover the inner end flush.
  • the punching pin (s) in the working position are consequently supported with their inner ends on the control element, which thus also takes on the function of an inner stop.
  • the punching pin (s) in the working position for the sake of simplicity, it is assumed below that only one punching pin is held in the working position at any time, without this being intended to be restrictive - first transfer the axial force occurring during the punching to the control element or controls assigned to it, which then in turn forwards it to the punch.
  • Another variant of the invention provides that the or Punch pins in their rest position with their inner end project beyond their bore inwards and they can be locked in this rest position.
  • the control member (s) in question clears or keeps the necessary space for the punching end of the punch which extends inwards.
  • the punching pin or pins in the rest position are locked in this position by means of a spring.
  • a compression spring is preferably used, which can engage an outer collar of the punching pin, for example. If this spring expediently acts continuously on the punching pin, the latter goes into its rest position at the moment in which the control member allows the inward movement, directly or indirectly.
  • the rest position can be secured by holding the punching pin in this position by means of a locking device. The force required for snapping can come from the return spring mentioned.
  • a preferred embodiment of the invention is characterized by at least one control member designed as a slide, assigned to the base body, in particular mounted thereon, with at least one recess or opening for the entry of the inner die end or ends of the die or idle dies.
  • the slider thus moves over the inner ends of the punch pins assigned to it and its shape enables it to work, for example, a punch pin holds down position, while the other can enter its opening or recess in the event of spring loading and thereby assume its rest position.
  • the slide can be designed so that it holds two or more punch pins in the working position at the same time.
  • it can also be constructed so that all the punching pins assigned to this slide are in the rest position. This is expedient and possibly also necessary if there are several slides and, for example, only a single punching pin should be in the working position.
  • the or each slide can be displaced transversely to the punching direction and in particular can be locked in the possible end or intermediate positions.
  • the direction of displacement of this slide is therefore rectilinear and, as a result, the punching pins which it can control are preferably at least approximately one behind the other. In any case, however, they must be arranged so that they can be released or held in the working position by the slide in any possible slide working position.
  • a further development of the invention is characterized by an actuator for the slide or slides, which is attached to the punch or a bell or the like surrounding it.
  • an actuator for the slide or slides which is attached to the punch or a bell or the like surrounding it.
  • the slide has a recess for the simultaneous reception of two inner punch ends.
  • the receptacle can be dimensioned such that it is able to accommodate all of the inner punch pin ends at the same time. The latter is again necessary if two slides are provided per punch.
  • a rotary slide valve with the difference that the receptacle has the shape of a circular groove or circular depression. It can also be divided into individual partial recordings, which can only accommodate one punch end at a time.
  • Another variant of the invention is characterized in that the or each slide is rotatably mounted on the base body about an axis running in the punching direction.
  • This slide is therefore a rotary slide for which the above applies analogously, with the difference that its movement is not a straight line but a circular one.
  • all of the punching pins to be controlled by it are at least approximately on a circular line.
  • the axes of the punching pins lie exactly on a circular line and, in the case of the linearly movable slide, exactly on a straight line.
  • the geometric axis of rotation of the slide designed as a rotary slide with the geometric axis of a punch of the Ma line collapses this punch can be provided with a central clamping pin, the axis of which is identical to that of the punch.
  • the rotary slide valve preferably has an annular shape and is centrally penetrated by a fixing pin of the punch or the base body. The end of the fastening pin assigned to the base body can be used as a bearing pin for the slide.
  • control member is formed by the free end of the punch or is immovably connected thereto and the base body with the punch pins is rotatably mounted on the punch and that the die, in particular, rotates synchronously with the base body on a machine frame, table or the like. is stored.
  • the control element is expediently produced as a separate part and immovably fastened to the lower end of the punch.
  • a suitable rotary drive which is also advantageously located on the punch, the base body with the punch pins can be rotated by an angle sufficient to move the punch pin in the working position into the rest position and the neighboring punch punch or another punch pin that is even further away in the circumferential direction to put in working position.
  • the die is rotated synchronously, which is advantageously equipped with its own rotary drive.
  • the two rotary drives can be connected to one another or at least controlled in such a way that exactly the correct die or the correct die opening is always assigned exactly when changing from one punching pin to another.
  • the clamping pin of the base body is also a pivot, which is why the bore must be designed so that the pin can be rotated in the receiving bore of the punch without hindrance.
  • a further embodiment of the invention provides that the base body with the punching pins is rotatably mounted on the control member held non-rotatably on the punching plunger and the die is in particular rotatably supported on the machine frame, table or the like, the geometric axis of which is in the working position Punch pin coincides with the geometric axis of the punch.
  • the punching plunger working in each case is advantageously aligned centrally to the geometrical axis of the punching plunger, which is advantageous for loading the machine and also the punching tool.
  • this construction does not require a zero point correction if you change from one punch to another and the machine works with program control. With the construction described above, it is also possible, however, to do without such a zero point correction the punching pin in the working position is offset to the side slightly from the geometric axis of the punch.
  • the control member has a clamping pin for insertion, in particular locking, into a receptacle of the punch and a parallel but laterally offset bearing pin for the base body which projects in the opposite direction.
  • a bearing pin is provided on the base body, which is held in a bearing bore of the control member.
  • the lateral distance between the two pins is selected so that when the base body is rotated through the various working angles of rotation, one of the punching pins of this punch is always exactly aligned with the geometric axis of the punch.
  • the base body has an annular or disc-shaped shape and expediently one also selects a disc shape for the control element which corresponds approximately to that of the base body in terms of its diameter.
  • the clamping pin is, however, attached to this disk of the control element off-center.
  • control member has a circular arc-shaped recess for the projecting beyond the base body inner ends of the punching pins located g lun in Oxfordstel-.
