Definitions

  • the invention relates to a device with the features according to the preamble of Claim 1.
  • Perforated sheets are widely used in numerous industries, namely as Sieves and filters in the food industry, in Mining and in gravel pits, as protective covers Phono devices, construction and machine tools, as partitions and decorations, as components in household appliances, in office furniture, in aircraft and in Industrial building.
  • non-ferrous metals, or material combinations in sheet thicknesses between 0.3 and 30 mm are basically two types of presses used, namely perforating wide presses to sheet with continuous or periodically interrupted hole patterns from tape or sheet material in series manufacture, and strip presses, to single sheets, larger ones Sheet formats and thicknesses with individual hole patterns to manufacture.
  • the punches of the perforating wide press are in rows arranged transversely to the feed direction. You are in one Stamp holder led. A ram pushes the press them through a stamp guide plate and presses them through the sheet into corresponding holes in the Die. A scraper prevents the sheet from Withdrawing the stamp will stick to it. He is rigid or becomes out of phase with the pestle operated.
  • a perforating device in a press for strip-shaped thin sheet with a feed device for gradual conveying of a sheet known through the perforation stage is held during a rest phase by means of a Perforated tool from die and stamp.
  • a Perforated tool from die and stamp are one or more spools provided, each one or more rows of stamps in the feed direction of the sheet can cover, which can be moved transversely to the feed direction of the sheet and so depending Establish or interrupt the flow of force to one or more stamps according to position.
  • the control slides are offset from one another in the feed direction of the sheet metal and overlap arranged independently of each other.
  • the invention has for its object with simple Medium to manufacture common hole patterns in series, the an increasing and / or decreasing in the feed direction can have a hole-free area, e.g. Circles, triangles, Trapezoids etc.
  • a Control spool from one side transverse to the feed direction gradually pushed into the power flow be so that after each feed one or more Stamp can also be activated. It arises like this triangular or trapezoidal lace pattern. Is the Control spool shorter than the associated row of punches and if it is gradually moved back and forth, let create serpentine hole patterns.
  • stamps can still be separately be activated even if they are only a small one Be at a distance from each other since the control spool in any small steps can be adjusted.
  • An electrical or expediently serves this purpose hydraulic stepper motor, via pinion, toothed belt and a rack that attaches to the spool is driving this.
  • the stepper motor on the plunger mounted directly so that he can move the plunger participates and no relative movement between the plunger and the stepper motor has to be considered.
  • the telescopic with a drive spindle works together.
  • More lace patterns e.g. B. circles, ellipses, parabolas etc.
  • each spool can one or more rows of stamps of the same or different lengths can be assigned. You can the front parts of the spool are designed in this way be that only one stamp when moving a row of stamps is activated.
  • a wide perforating press usually contains the following Assemblies, namely a perforating device 1, a Feed device 2, a separating and notching device 3, a pair of cutting scissors 4 and corresponding, Drive devices, not shown.
  • the Modules are mounted in a press body 5.
  • the feed device 2 comprises two pairs of feed rollers 6, each in front and behind the perforating device 1 are stored in the press body 5 and between which a sheet 39 gradually in time with the Press strokes promoted by the perforating wide press becomes.
  • the feed direction 7 and the stroke direction 16 are marked with arrows.
  • a press table 8 belongs to the perforating device 1, on which a die 9 by means of clamping devices 10 is attached.
  • a perforated plate 11 forms the upper one Part of the die 9, over which the sheet 39 is guided.
  • the perforated plate 11 and the die 9 have holes 12 and Bores 13 in the punch 15 during the perforation process intervene by removing 39 Punch out the corresponding sheet metal.
  • the stamps 15 are in a stamp holding plate 18 held longitudinally displaceable.
  • the stamp guide plate 17 guides the stamp 15 in Longitudinal direction and at the same time ensures that the Sheet 39 does not get stuck during the upward stroke. she can be rigid or as shown by a separate one Scraper drive 19 out of phase for ram movement be moved.
  • the stamp holding plate 18 is on a plunger 14 attached. This is not brought closer by one shown eccentric drive and leads a stroke movement in time. Above the stamp 15 a free space 22 is provided in the plunger 14, in which the Stamp 15 can withdraw, provided they are not from a control device can be activated.
  • control device consists of Control spools 20 which are transverse to Feed direction 7 can be moved into the free space 22 and the space between stamps to be activated 15 and fill in the plunger 14. So that the flow of power between the plunger 14 and the plungers 15 made so that they penetrate through the sheet 39 can.
  • the control slide 20 are in one on the tappet 14 attached slide guide 21 out.
  • Stepper / servo motor 38 drives them over a Sliding sleeve 37, a drive spindle 36, pinion 35, 33, 31, 27, toothed belts 34 and 30 and one Hollow shaft 32, shaft 28 and rack 26 on.
  • the Stepper / servo motor 38 and the sliding sleeve 37 are on Press body 5 mounted while the rest Drive parts are attached to the plunger 14 and with join in the lifting movement.
  • the relative movement between the ram 14 and the press body 5 is the same the sliding sleeve 37, which telescopically with the Drive spindle 36 works together.
  • the control slide 20 can be adjusted by one drive; expediently, however, they are used by several Drives driven independently of each other.
  • Fig. 4 shows in addition to Control slides 20 control strips 23, 24 on Rest stages 25 lie one above the other.
  • the control strips 23, 24 can be moved against each other while doing so take different rest positions, in which they in Stroke direction 16 a different total thickness 40 to have.
  • different gaps can be realized between the stamps 15 and Control slides 20 or the control strips 23, 24 different gaps.
  • more complex hole patterns can be made, e.g. B. can with the largest Total thickness 40 from the spool 20 the shortest Stamp 15 can be controlled during the longer Stamp 15 regardless of the position of the Control spool 20 are always activated.
  • Will the Control strips 23, 24 in a position with a shifted lower overall strength 40 remain shorter stamp 15 regardless of the position of the Control spool 20 inactive while the longer stamp 15 are activated by the control slide 20.
  • the control slide 20 of FIG. 5 are in Feed direction 7 offset from each other and overlap by a certain amount.
  • the stamp 15 are also arranged in staggered rows. So can a spool 20, the stamp 15 on one Activate sheet metal side while the other control spool 20 the stamp 15 on the other side of the sheet activated.
  • the number of each can Control spool 20 assigned stamp 15 equal to or be unequal and divided symmetrically or asymmetrically his.
  • a control slide 20 can also have several rows Stamp 15 can be assigned. By having a front edge 41 designed accordingly, for. B. bevels in Adjustment direction of the control slide 20 one or more Stamp 15 of a row before the stamp 15 of one another row can be activated.
