Definitions

  • the invention is related to an apparatus as for example known from EP-A-0 088 152 for manufacturing work pieces using pressure, such as bending, punching etc, said apparatus comprising principally a fixing surface and a carrier with respect to the table, for a thereon affixed pressure device such as a hydraulic cylinder.
  • An apparatus of the type described in the preamble is usually used for a single pressure stroke, for example the punching of work pieces, where the direction of the stroke is not suitable for pipe bending.
  • the invention aims at providing a similar apparatus which is universal but nevertheless constructionally simple.
  • the invention provides an apparatus wherein the carrier is adapted to an axis parallel to the table, crossing the pressure axis of the pressure device.
  • the pressure device can be brought under any desired angle regarding the table. Especially in the first position wherein the pressure line falls vertically on the table, and in the second position wherein it runs parallel thereto.
  • a support table is indicated with the number 1, which can be mounted on any frame in any way desired.
  • the surface of the table 1 serves as a fixing surface 2, for the work piece to be machined.
  • a fixing surface 2 for the work piece to be machined.
  • a pivoting support 3 in the shape of a U shaped yoke straddles the table 1, so that the vertical cheeks or arms 4, of the yoke 3, are situated on either side of the table 1.
  • each arm posesses two through holes, 5, 6, through which a pivot pin 7 extends into the side of the table 1, and a locking pin 8 respectively.
  • the two pivot pins 7 on both sides of the table form a hinge or pivot line A-A which runs parallel to the fixing surface 2 of the table 1.
  • the line A-A runs at a determined distance below the fixing surface 2, which distance is equal to the distance D between the front edge of the pivot arm 4, and the pivot line A-A.
  • each arm is also S or Z shape constructed, such that the body 9 of the yoke 3 springs out above the fixing table 1 with regard to the axis A-A.
  • This body plate 9 carries a pressure unit 10, in the form of a hydraulic cylinder which is operated via a pressure source 11, and a two way valve 12.
  • the cylinder ram 13 moves up and down on a line B-B in figure 1.
  • the pressure line B-B crosses the pressure line A-A, whereby the distance between these two lines is at least equal to distance D.
  • a punch unit is created very simply with the arrangement shown in fig. 1.
  • the punch tool can be simply and easily fastened to the fixing table 2 using dowels 15 and the pre-drilled holes 16 in the table.
  • Fig. 2 shows the apparatus in fig. 1 in an other position whereby the yoke 3 is pivoted counter clockwise following the arrow P2. This pivoting can be achieved by removing the locking pin 8 from the hole 6, lowering the yoke thereafter, and replacing locking pin 6 in the arm 4 in a second hole 17, in the side of the table 1.
  • the ram 13 can push against the side of the workpiece W along a line B-B, whereby a bending action takes place.
  • the invention is not limited to the embodiment described above.
  • the yoke 3 another form, for example, as a projecting yoke with single arm, or an arm shaped other than the indicated S or Z shapes.
