Definitions

  • the object of the invention is achieved by a manufacturing device for forming workpieces made of sheet metal with two parallel aligned pressing beams, which are adjustable by means of a drive device in a direction perpendicular to the longitudinal extent of the pressing beam direction relative to each other.
  • the press beams can be equipped with a variable number of bending tools, wherein the bending tools are arranged one behind the other in the longitudinal extension of the press beams.
  • the production device furthermore has a control device connected to the drive device for influencing the operating behavior of the production device and a positioning means for determining the position of the bending tools relative to the longitudinal extension of the pressing beam.
  • the positioning means includes a rangefinder based on the use of acoustic or electromagnetic waves. This has the advantage of a particularly flexible feasibility of the setup process and also that the bending tools themselves need not have separate and specially designed facilities for their accurate positioning.
  • the design of the manufacturing device, according to which the positioning means comprises a laser rangefinder, allows a high accuracy in the position detection.
  • the manufacturing device 1 has two opposing press beams 15, 16 which extend over a length 17, generally of the intended machine size or working length for bending the sheet metal parts 3 is fixed.
  • the positioning means 45 or its laser rangefinder 48 can be operated via the control device 59 or the operating terminal 60. Like the operating terminal 60, the positioning means 45 is also conductively connected to the control device 59 for this purpose.
  • the control device 59 is equipped with an evaluation unit 63 preferably formed by a software. A value of a distance 64 of the end face 52, 55 of the bending tool 36, 37 is measured by the laser rangefinder 48 as an actual value and can be performed in the evaluation unit 63, a comparison with a preselected desired value of the distance 64.
  • the evaluation unit 63 is further adapted to a deviation of the actual value of the target value of the distance 64 with Help a signaling device 65 display.
  • the display by the signal device 65 may be formed by an optical or an acoustic but also by a combination of optical or acoustic display.
  • Fig. 4 is a further and possibly independent embodiment of the manufacturing device 1 is shown, again for the same parts the same reference numerals or component names as in the previous Fig. 1 to 3 be used. In order to avoid unnecessary repetition, the detailed description in the previous ones will be used Fig. 1 to 3 referred or referred.
  • the markings on the end faces 52, 55 of the bending tools 36, 37 are automatically recognized by an evaluation software provided in the control device 59.
  • the markings may be formed, for example, by barcodes.
  • the Fig. 5 shows a further embodiment of the manufacturing device 1 with an alternative embodiment of the positioning means 45.
  • the housing 54 of the positioning means 45 an adapter 68 which is designed such that it is attached to the tool receiving device 35 of the press beam 15 and the press beam 16 can be.
  • the positioning means 45 formed in this way can therefore only be positioned or fixed to the production device 1 on the pressing beam 15, 16 as needed, that is, only for the duration of the actual setting-up process.
  • the adjustable holding device 53 of the laser rangefinder 48 this can turn between a position in which the beam direction 51 is aligned with the end face 52 of the bending tool 36, and a position in which the beam direction 51 is aligned with the end face 55 of the bending tool 37, reciprocated.
  • the distance measurement or the measurement of the distances 64 is carried out with the positioning means 45 using electromagnetic radiation, that is in this case using the laser rangefinder 48.
  • electromagnetic radiation that is in this case using the laser rangefinder 48.
  • the distance measurement can be carried out according to the principle of transit time measurement of the electromagnetic or acoustic waves.
  • a tolerance range of +/- 1 mm can be set for a first tool station and a tolerance range of +/- 0.5 mm for another tool station, etc.
  • the operator it is also possible for the operator to set tolerance ranges for permissible deviations entered at the operator terminal 60 and these are taken into account by the evaluation unit 63.
