Definitions

  • the present invention relates to a device for folding a blank.
  • FR-A-2,750,625 folding a metal or partially metallic blank using a device which comprises two blanks holding the blank, and a folding tool of this blank around an angle, for example defined by one of the clamps blanks.
  • This folding tool has a generally C-shaped cross section. At each of the two ends of the C, this folding tool has a free edge. For folding, a non-immobilized portion of the blank passes between the free edges of the folding tool. One of the free edges then performs folding by exerting a thrust on the non-immobilized blank portion, which tilts around the edge of the corresponding blank holder.
  • the size of the C determines the folding capacity of the device and the ease of release of the blank after folding.
  • the size of the arms of C determines the maximum dimension that the blank portion tilted during folding can have in a direction perpendicular to the immobilized blank portion. This maximum dimension can only be increased by increasing the size of the folding tool and therefore of the device equipped with this tool.
  • the size of the folding device and the weight of the moving parts of this device become very important.
  • the force applied to the arms of the C due to the folding resistance of the blank, tends to open the C. This effort is all the more likely to deform the structure that the arms of C are long.
  • each free edge of folding must be successively brought into contact with the blank.
  • the invention intends to remedy more particularly by proposing a folding device having a large folding capacity, with a limited space requirement and allowing short cycle times and low energy consumption, when the performing a succession of inverted folds on a blank.
  • the invention relates to a device for folding a blank comprising a support, means for immobilizing by clamping a portion of the blank, a mobile tool for folding the blank comprising two folding arms supported by a structure. and means for operating the folding tool.
  • This device is characterized in that the arms are movable relative to the structure and relative to each other, the operating means comprising on the one hand operating means of the structure to move at least in a direction substantially parallel to the immobilized blank portion and secondly, two actuators adapted to move each of the arms, independently of the other arm, in a direction substantially perpendicular to the immobilized blank portion.
  • the arms of the folding tool are movable relative to each other, it is possible to increase the folding capacity of the device and to facilitate the release of the blank after folding, while maintaining a limited size of the device.
  • the cycle times and energy can be optimized in the case of the realization of a succession of reversed folds on the blank, since it is possible to anticipate the relative position of the two folding edges as a function of the folds. achieve.
  • the folding device 1 shown in FIG. 1 comprises two blank holders 3 facing one another and a folding tool 5 mounted on a support or frame 7.
  • a blank 2 intended to be folded in a direction perpendicular to its main plane represented by the axis X-X 'in Figure 1, is immobilized between the blanks 3.
  • the blank 2 is completely metallic.
  • it may be a sandwich structure composite blank comprising two metal sheets and a polymer thickness between these two sheets.
  • the folding tool 5 comprises a structure 51 and two folding arms 53 and 53 'supported by this structure.
  • Each of the arms 53 and 53 ' is slidably mounted relative to the structure 51 and relative to the other arm.
  • the sliding is carried out using rectilinear guide means which, in the example, comprise respectively two ball guides 55 mounted between the structure 51 and the arm 53 and two ball guides 55 'mounted between the structure 51 and the arm 53 ', in the extension of each other.
  • the arms 53 and 53 ' are of elongated shape and comprise, at their ends remote from the structure 51, free edges 531 and 531' of thrust of the portion of the blank 2 which exceeds blanks 3.
  • the structure 51 also elongated, is generally triangular section.
  • the structure 51 is slidably mounted on the support 7. The sliding of the structure 51 is carried out using guiding means rectilinear comprising two ball guides 9 mounted between the structure 51 and a rail 71 of the support 7, in the extension of one another.
  • An actuator 8 is articulated to the support 7 and the structure 51 so as to maneuver the latter in the direction VV 'of sliding of the structure 51 relative to the support 7.
  • the actuator 8 is hinged relative to the support 7 by means of a shaft 81 of axis ZZ 'perpendicular to the plane of Figure 1, and with respect to the structure 51 by means of a shaft 83 of axis parallel to the axis ZZ'. Due to the triangular shape of the structure 51, its sliding relative to the support 7 in the inclined direction VV 'induces an overall displacement of the structure 51 and arms 53 and 53' in the direction of the axis XX 'and a direction YY 'perpendicular to the directions of the axes XX' and Z-Z '.
  • Two actuators 6 and 6 ' mounted on the support 7, respectively maneuver the arms 53 and 53' independently of one another in the direction Y-Y '.
  • Each arm 53 or 53 ' is thus able to slide in the direction YY' relative to the structure 51 and to the other arm, as represented by the arrows F and F 'in FIG. 1.
  • the rods 61 and 61' actuators 6 and 6 ' are able to slide respectively relative to the arms 53 and 53' in the direction of the axis X-X ', via ball guides 4 and 4'.
  • the zone Z of interaction between each actuator 6 or 6 'and the corresponding arm 53 or 53' is variable along this arm as a function of the position of this arm in the direction of the axis X-X '.
  • the sliding assembly of the rods 61 and 61 'on the arms 53 and 53' makes it possible to operate the arms in the Y-Y 'direction, while taking into account the overall displacement in the direction of the axis XX' of the structure 51 and arms 53 and 53 'resulting from the sliding of the structure 51 relative to the support 7 in the direction V-V '.
  • each of the actuators 6 and 6 ' can be connected by a hinge to the arm 53 or 53' corresponding.
  • the rods 61 and 61 'of the actuators 6 and 6' may for example be pivotally mounted on the arms 53 and 53 ', the actuator bodies 6 and 6' being pivotable relative to the support 7.
  • the actuators 6, 6 'and 8 are hydraulic cylinders.
  • the mobility of the structure 51 and the arms 53 and 53 ' obtained by means of the ball guides 4, 4', 9, 55 and 55 'and the actuators 6, 6' and 8, allows an optimization of the movements of the folding tool 5 to the blank 2.
  • the device 1 makes it possible to apply a folding force P as close as possible to the folding zone.
  • the device offers a large folding capacity and increases the ease of release of the blank 2 once it folded.
  • the relative mobility of the arms 53 and 53 ' makes it possible to move the two arms by anticipation as a function of the folds to be made.
  • the positive folding arm can be moved to the next folding zone while the negative folding arm is in the process of perform a folding. It is thus possible to reduce the cycle time.
  • Each arm 53 is lighter than the entire tool 5, it can reduce the energy consumed during the folding of a blank.
