Definitions

  • the invention relates to a folding machine with on a machine frame in the longitudinal direction arranged lower cheek, one with respect to the Lower cheek can be raised and lowered, which runs parallel to the lower cheek and one to the Upper and lower cheek parallel bending cheek, which around an axis parallel to the cheeks to the Bend one with the upper beam lowered this and the lower cheek clamped sheet is pivotable.
  • Such folding machines are manual or motor drive in use, e.g. in sheet metal processing companies, locksmiths or also on construction sites, e.g. for editing Sheet metal frame elements or the like
  • At least one of the cheeks at one or both ends with first means of connection to the immediate Is connected to another machine and that with distance from the cheeks in the back Area of the machine a second lanyard is provided, which for aligning alignment two interconnected machines is adjustable in length.
  • a convenient length of the base module cheeks is two meters. By keeping the cheeks on protrude from both sides of the machine frame, can already be done with a modular basic version Work on workpieces over two meters long. There in many workshops two or more anyway Pivot bending machines are required the proposal according to the invention the simple connection two basic modules to form a folding machine from four meters cheek length or above, so for certain applications also include long workpieces can be edited.
  • the first connecting means which the cheeks are provided only on the Bending beam are limited.
  • the stabilizing effect of the second Lanyard which is expedient a protruding in the connection direction on the machine frame swiveling pull / push rod, which by means of one of those to be connected Machine is screwable.
  • a folding rod is sufficient, which on the side wall pointing to the connection point of the machine frame is articulated. Your length corresponds approximately to the lateral overhang of the Cheeks over the machine frame.
  • the machine frame is advantageous in the way designed that it consists essentially of two Foot part connected to lower beam and bending beam exists, which have cross parts at the top rear ends are hinged, which are wear the upper cheek.
  • the machine can be used on construction sites.
  • the folding machine according to the drawn Embodiment is on a machine frame built, which a left foot part 1a and a right foot part 1b includes. Both foot parts 1a, 1b stand on castors 2, which by means of a Device 3 for height adjustment on uneven floors are adjustable. They are on the machine frame Cheeks of the folding machine mounted, namely the Lower beam 4, upper beam 5 and bending beam 6.
  • the cheek cross section is illustrated in Fig. 3.
  • a transverse part 7 of the foot part 1a is a Lower beam 8 mounted with which an L-shaped Profile rail, which the lower beam 4 forms, screwed or otherwise connected is.
  • a rocker 9 is about the pivot point 10 with respect to the Cross part 7 by actuating bracket 11 pivotable, so that when operating the bracket 11 in Direction R the upper beam 5 opposite the lower beam 4 takes off.
  • the upper beam 5 is short Upper beam 12 with the front end of the Swing arm 9 connected.
  • the bending beam 6 sits on the lower beam 4, so that it by operating its bracket 13 in the P direction one parallel to the longitudinal direction of the cheeks extending axis is pivotable upwards. A between the upper cheek and lower cheek Sheet metal strips can be adjusted accordingly in this way be folded at the top.
  • a tab 14 screwed, which protrudes beyond the assigned end of the bending beam, as can be clearly seen in FIGS. 1, 2 and 4.
  • the tab 14 is by means of two countersunk screws 15 on corresponding end of the bending beam 6 attached.
  • Fig. 4 shows one of two basic modules composite folding machine.
  • a pull / push rod 20 provided on each machine module.
  • the free ends the push rods are by means of a spindle nut 21 connected, when they rotate either Distance can be shortened or extended. On this way is a simple flush alignment of the two machine modules possible.
  • the pull / push rods 20 are each articulated to the corresponding sides of the cross members 7 articulated where corresponding brackets 22 are provided by which each runs a pivot pin 23 (see. Fig. 2).
