Definitions

  • the present invention relates to a device for handling a part during successive operations of working of said part with a press, in particular a press brake, provided with an adjustable position stop.
  • the aim of the present invention is to propose a device making it possible to partially or even completely eliminate human manipulation of the part during successive operations of working of this part with the press, while avoiding entrusting these tasks to a separate device, that is to say to a robot.
  • the invention relates to a device for handling a part during successive operations of working of said part with a press, in particular a press brake, provided with an adjustable position stop, as defined in claim 1.
  • the device of the present invention can advantageously be used on any press, the implementation of which requires a combination of horizontal and vertical displacements of the part to be treated.
  • the press brake partially shown in Figures 1 to 9 comprises a fixed lower deck 1 and a movable upper deck 3.
  • a pair of lower tools 2, 2 ', interchangeable by rotation, are mounted on the lower apron.
  • the interchangeable arrangement, known per se, of the lower tools 2, 2 'and respectively upper 4, 4' makes it possible to have either a lower punch 2 cooperating with an upper die 4 (in solid lines in FIG. 1), or a lower die cooperating with an upper punch (dashed in Figure 1).
  • a work rest 5, integral with the lower apron 1, is intended to receive the piece to be folded 7 before it is taken over by the automatic handling device.
  • the press further includes a rear stop 8 adjustable in height and horizontally, so that the stop finger 9 can move vertically along the R axis and horizontally along the X axis.
  • a clamp 10 is mounted at the end of the finger or stop carriage 9.
  • This clamp comprises a V-shaped rear part 12, arranged to cooperate with a seat 13 of corresponding shape, produced at the end of the stop finger 9 , over the entire width of the stop finger, from one side to the other of the stop finger. Maintaining the clamp 10 against its seat 13 is ensured by means of a flexible tie rod 14, integral with a pneumatic cylinder 15, mounted inside the stop finger 9.
  • the clamp is arranged so as to allow the gripping of the part 7 when it has been deposited on the workpiece rest 5 (FIG. 1).
  • the clamp has a slot 11 intended to come and surround the edge of the part 7 until said edge abuts against the bottom of the slot 11, the other end of the part 7 abuts against the element of stop 6 mounted on the workpiece rest 5 ( Figure 2).
  • a blocking device (which will be described below in relation to FIGS. 11 and 12) is put into action inside the clamp so as to block the part in the clamp.
  • the part 7, which is thus gripped by the clamp can be moved therewith by simple horizontal and vertical displacement of the stop finger 9 (FIG. 3).
  • the press may include several clamps 10.
  • the beam of the rear stop 8 may comprise several carriages or stop fingers 9, at the end of each of which is mounted a clamp 10.
  • several clamps 10 can also be mounted at the end of the same stop finger 9.
  • the flexible tie rod 14 can be made in the form of a cable, a chain, a band, or any other suitable means.
  • the pneumatic cylinder 15 can be replaced by a reel, in particular when several clamps are provided.
  • the deposition of the part 7 on the workpiece rest 5 can be carried out either manually, or by horizontal transport by conveyor, or using a vacuum gripping device 20, such as that shown in FIGS. 1 and 10, and which allows the automatic entry of a part in a stock and its movement to bring it to the work rest 5.
  • a vacuum gripping device 20 such as that shown in FIGS. 1 and 10
  • any other method for bringing a work piece to the work rest 5 can be provided .
  • FIGS. 1 to 9 comprising two pairs of tools interchangeable by rotation, is described here only by way of example.
  • the device according to the invention can be used with any other type of tool that is usually used on presses.
  • the clamp 10 and its mounting at the end of the stop finger 9 are shown in more detail in FIGS. 11 to 13.
  • the device for locking the workpiece 7 in the slot 11 of the clamp can be produced using 'a single-acting cylinder 16, combined with a spring 17 for unlocking the part.
  • the bottom 18 of the slot can be made elastic by means of a spring 19.
  • control of the entire device can be carried out using any suitable control device known per se, such as for example an electronic control device.
