Definitions

  • the present invention relates to a press-die positioning system which facilitates aligning the referencing holes on the die and the conical pins on the press bolster on top of one another, according to the preamble of claim 1.
  • Sheet metals are shaped in the dies by means of the press.
  • the dies on the line should be changed.
  • the dies are placed on the press bolster by the help of a crane, and when it is being placed, the referencing holes on the die and the conical pins on the press bolster are aligned on top of one another. This way, after the press bolsters move the dies towards the production line, the die is placed correctly on the production line.
  • a difficulty is encountered during aligning the referencing holes on the die and the conical pins on the press bolster on top of one another due to the decrease in the angle of vision.
  • the die will not be placed on the press bolster accurately and thus this will cause failure to shape the sheet metal accurately as well as damaging of the referencing holes, conical pins, the die and the press bolster.
  • the requirements of decreasing lot numbers, increasing die changing frequency and reducing set up times, increase the need for speeding up and facilitating die centering.
  • the Japanese patent document no. JPH0839153 (A ), an application in the state of the art, discloses a device which enables to decrease the errors of distance and radius by marking a workpiece via laser beam.
  • the workpiece (W) is placed on a lower metal mold (7).
  • the cross width of the workpiece (W) is roughly adjusted to the cross width of the upper metal mold (9).
  • the device includes a laser irradiation device (21) and a laser nozzle (23).
  • the angle of the laser nozzle (23) is adjusted according to the S-S line which is at the working center of the upper metal mold (9).
  • the laser irradiation device (21) is located alongside an upper bolster and a lower metal mold (7).
  • the Chinese utility model document no. CN201128278 (Y ), an application known in the state of the art, discloses a laser marking machine used in casting. Marking during arranging the sand core is performed by the laser radiating position of the laser marking machine. During use, firstly the sand core is arranged on the work bench, and then the laser marking machine is set, and the marking button is pressed. The laser marking machine emits large-power laser beams. The laser beams are radiated on the sand core.
  • the invention has the advantages of high speed, high automation degree, clear font, neatness, good standardization, and ability to reduce the labor intensity.
  • the United States patent document no. US 3696489A discloses a bench top is mounted on telescoping legs supported by a base member and can be raised and lowered relative to the base.
  • the bench top is straddled by a vertical frame formed from a pair of laterally spaced posts connected at their upper ends by a cross beam.
  • Supported by the cross beam above the bench is a trolley that is movable along the beam and from which the top section of a die can be suspended while the bottom section of the die is supported by the bench top and raised or lowered by it.
  • the objective of the present invention is to provide a press-die positioning system which enables to place the die onto the press bolster.
  • Another objective of the present invention is to provide a press-die positioning system which helps to perform pressing operation accurately.
  • the press-die positioning system (1) which facilitates aligning the referencing holes on the die and the conical pins on the press bolster on top of one another, basically comprises
  • a lower die (2) and an upper die (3) are provided with the purpose of shaping sheet metals.
  • the lower die (2) is arranged on a bolster (7).
  • It comprises two dies namely lower die (2) and upper die (3).
  • lower die (2) should be lifted from the lifting lugs (5) on the sides thereof by the ropes (6) by the help of the crane (4) and arranged on the bolster (7), and then the bolster (7) should move the lower die (2) and the upper die (3) towards the production line.
  • the referencing holes (8) on the bottom part of the lower die (2) are aligned with the conical pins (9) on the bolster (7) on top of one another to enable accurate placement.
  • the conical pins (9) and the referencing holes (8) are at least two of these conical pins (9) and the referencing holes (8) in order to arrange the lower die (2) accurately, and preferably they are not close to each other.
  • This linear light emitted by the laser (10) is aligned with the guiding lines (11) on top of one another, and when the lower die (2) descends from this position vertically, the conical pins (9) can precisely fit into the referencing holes (8).
  • the lower die (2) By means of referencing this beam emitted by the laser (10) with the guiding lines (11), the lower die (2) will easily be placed on the bolster (7) without a need for alignment each time.
