Definitions

  • the present invention relates to a press tool provided with two mutually opposing, registering and relatively movable column-mounted carriers for tool parts for working an elongate workpiece, a device mounted on the first of the carriers for advancing the workpiece through the tool formed by the tool parts and means mounted on the second carrier for actuating the advancing device.
  • Press tools of the kind described above and advancing means which can be used in conjunction therewith are already known, e.g. from the Swedish Patents Nos. 152 989 and 188 533, the US Patents Nos. 1 434 192, 1 968 479 and 2 342 049, the British Patent No. 626 689 and the German Patent No. 621 052.
  • press tools include an integrated advancing means, which involves considerable advantages, such as greater exactness in advancing stroke, less material waste, better utilization of available space and greater operational reliability, such press tools do not form units which can optionally be used in practically any kind of press at all and which can be easily changed and moved to another press when required. Furthermore, these press tools have a complicated structure with a large number of parts, resulting in that tolerances of the finished workpiece cannot be kept (particularly after the tool has been used for some time) and that costs for the manufacture of the tool are high.
  • One object of the present invention is to at least partially remove the disadvantages with already known tools and to provide a press tool with integrated material advance, which can be made as a unit and without having to be dismantled can be used in practically any kind of press at all, and which comprises a small number of parts of simple embodiment, partly to cheapen the tool, and partly to ensure that an expensive workpiece, such as a gold or silver strip can be worked without unnecessary waste of material and with maintenance of predetermined tolerances.
  • the press tool illustrated in the Figures comprises a lower plate 1 and two upstanding columns 2, and an upper plate 3 with downwardly directed sleeves 4 received in holes 5 made in the plate 3.
  • the upper plate 3 is guided for registering movement relative the lower plate 1 by the columns 2 received in the sleeves'4 and holes 5.
  • the aforementioned details,1-4 form a unit including a tool for working a strip-like workpiece as well as an advancing device for the workpiece.
  • the plate 3 can be displaced away from the plate 1 without restriction and can be displaced towards the plate 1 against spring bias exerted between plates 1, 2, and excercised by compression springs 20, which are guidable between, and removable from, plates 1, 2.
  • the springs also form spacers for keeping the plate 3 a predetermined distance from the plate 1 when the tool is unloaded, as illustrated in Figure 1.
  • the bottom plate 1 carries a first tool part, such as a die 6, and the upper plate 3 carries a second tool part such as a punch 7 including a punch holder 7a for a punch element 7c thrusting into a punch guide 7b.
  • the guide 7b is mounted at a fixed distance from the die 6 and accommodates a compression spring 7d together with a ball 7e biased by the spring.
  • the lower plate 1 is provided with two guider rails 8, between them guiding a slide 9 for rectilinear reciprocatory motion in relation to the tool parts 6, 7.
  • the slide 9 is provided with a nose 11 thrusting into a slot 10 in the plate 1, and two upstanding walls 12, in which is removably mounted a shaft 13; there being a stop pin 14 removably inserted in the upper face of each wall.
  • a U-shaped rocker 15 (see Figure 2) is pivotably mounted on the shaft 13 between the walls 12. Relative its centre line the rocker 15 is eccentrically mounted on the shaft 13.and is upwardly provided with a shaft 16 extending outwards on either side of the U-shaped legs, each end of the shaft being provided with a roller 17 which is rotatable. Between both legs of the rocker 15 the shaft 16 forms an attachment for at least one tension spring 18, the other end of which is attached to a holder 19 on the plate 1.
  • the press tool illustrated in the Figures is inserted as a unit in some suitable press, only the lower plate 1 being fixed to the lower press table, and this without needing to be oriented particularly accurately.
  • the piece on which work is to be performed namely a gold or silver strip 21
  • the strip is retained in the inserted position by friction between the die 6 and the ball 7e biased by the spring 7d.
  • the press is then operated, and its upper platen presses the plate 3 downwards against the bias of the springs 20.
  • the punch element 7c punches holes in the strip, or alternatively impresses it in some way. In conjunction with this operation, bevelled undersides of two legs dependent from the plate 3 engage against the rollers 17.
  • the shaft 13 is released from the walls of the slide 9 and from the rocker 15, the details 13, 15 then being assembled again on the slide 9 but with the rocker 15 oriented differently so that the edge 15a is to the left of the shaft 13 in Figures 1 and 3. Further to this measure, the stop pins 14 are removed and inserted in holes in the slide 9 to the right of the rocker 15.
