Definitions

  • ABSTRACT A self-lubricating perforator arrangement wherein a horizontal guide plate for the perforating needles comprises parallel upper and lower partial guide plates which define a capillary gap between them.
  • a unit situated above the partial plates contains an oil reservoir which communicates with the capillary gap to enable a regulated lubrication of the needles as they pass through the partial plates during operation.
  • Also contained in the unit is a channel directly above the needles and the plates to receive the chads.
  • the present invention relates to an arrangement for effecting the automatic lubrication of the perforating pins which, below the die, are guided in a special plate, in tape or card perforators, with the aid of a thinly liquid oil.
  • the latter is effected by means of an oil-saturated strip of felt arranged below the die-plate and along the perforating needles.
  • Lubrication achievable by this arrangement does not represent a satisfactory solution, because in this case the sliding surfaces and the cutting points are not provided with a sufficient oil film having a noticable effect upon wear.
  • attempts have already been made for extending the tool life by using materials particularly resistent to wear, or a favorable combination of materials and/or by using cutting edges of optimum design. This, as a rule, however, leads to unjustified high expenses. 7
  • the guide plate consists of an upper and a lower partial plate, with the surfaces facing one another, having been subjected to surface grinding, that the two partial plates are firmly clamped to one another, and that the upper one of these partial plates is provided with a borehole which is in a sealed communication with an oil tank or reservoir arranged thereabove.
  • the capillary effect appearing between the two partial plates of the guide plate serves to convey the oil in the exact proper dosage to the guide holes of the perforating needles.
  • FIGS. 1 to 3 of the accompanying drawings in which:
  • FIG. 1 shows a sectional representation of a perforating device designed in accordance with the present invention, on an enlarged scale
  • FIG. 2 shows the detail A of FIG. 1 on an enlarged scale
  • FIG. 3 shows the detail B of FIG. 1 on an enlarged scale.
  • FIG. 1 shows a tape perforator which is designed in accordance with the invention.
  • a channel 3a which serve to collect the chads 6 as produced by the perforator.
  • the usual inclination of the chad channel simultaneously serves as a separating wall with respect to the oil reservoir 3b which, together with the chad channel 3a, forms one unit 3.
  • the unit 3 is made of a transparent material.
  • the oil reservoir 3b which, for production-technical reasons, is open at the top, is covered by a plate 4 which, in turn, is provided with a filling hole 4a.
  • the oil reservoir 3b is provided at its bottom side, with an oil outlet 30.
  • the die-plate l is provided with a passage hole, through which the screw of the oil outlet 3c is permitted to project.
  • an oil retainer ring 7 is provided on the supporting surface between the unit 3 and the die-plate 1
  • a guide plate 8 composed of an upper and a lower partial plate 8a and 8b respectively.
  • This type of lubrication causes a minimum oil consumption only amounting to a few cubic centimeters for several thousand working hours. In this way it has become possible to combine the oil reservoir 3b with the chad channel 3a, and one single filling is sufficient 'for lubricating both the perforating needles 10 and the die-plate 1 during their entire service life, when made of conventional material.
  • An arrangement for effecting the automatic lubrication of the perforating needles arranged adjacent to the die-plate of tape or card perforators comprising a guide plate consisting of an upper and a lower partial plate, with the surfaces thereof firmly facing one another and defining a capillary gap, the upper one of said partial plates being provided with an aperture which is in communication with an oil reservoir arranged thereabove.
