  • the pliers halves automatically adapt to the shape of the piece of sheet metal which they are intended to grip. Whether a piece of sheet metal is in the pliers or not is indicated by a light barrier which has a transmitter 57 in the fixed jaw part 51 and a receiver 57 'in the movable jaw part 52.
  • the movable jaw part 52 is pivotally mounted about a pin 58 and carries a guide roller 59 at its end remote from the pliers half 55, which cooperates with a guide roller 60. With 61 a spring is designated, which keeps the jaw parts 51 and 52 open.

  • the slide 20 uses the guide arm 73 to carry out the theoretical movement of the gripping jaws 51, 52 calculated by the computer, which is composed of circular arcs. In fact, there are small deviations. which lead to tensions in the sheet metal with a rigid connection. On the one hand, this is clamped and deformed in the press and, on the other hand, it is held between the pliers halves.

  • the two vertical guide columns 15 are maneuvered in such a way that the open gripping jaws 35 of the pliers 34 grip over the side edges of the sheet metal plate and hold them in place as soon as the edge of the sheet metal plate contacts the base of the pliers mouth.
  • the pliers halves 55 are closed, the sheet metal plate is held in a vertical position and is lifted upward from the reference surface by the movement of the two gripper slides 20.
  • the rotary drive 67 is actuated until the metal sheet assumes the horizontal position and is supported by the rollers 43, 45 and 47.
  • the two guide columns 15 are moved in the horizontal direction together with the sheet metal plate supported by the rollers 43, 45 and 47 against the tool ram 101 of the sheet metal press 1, namely at a height which the same is inserted between the upper and lower tools 102 and 103 the sheet metal press enables.
  • the clamping force of the pliers halves 55 is temporarily reduced in order to position the sheet metal plate precisely.
  • the pliers halves 55 then close and the metal sheet is ready for processing.
  • the sheet metal plate held by the pliers 34 describes a precisely precalculated pivoting movement, which is carried out exactly by the gripping jaws 35 by the gripping jaws describing the path calculated theoretically and controlled by the computer.
  • This theoretically determined route does not exactly correspond to the actually described route, since there are always small deviations due to the sheet quality and other influences. These deviations would create stresses in the sheet metal, which can have an adverse effect.
  • the pistons are retracted into the pressure cylinders 75 arranged in a star shape, so that the cylindrical holders 72 can move and yield somewhat.
  • a further additional addition is also possible in that the relative movement between the movable pliers bodies and the remaining rigid parts of the guide is measured electrically and the determined differences are entered into the control for correcting the subsequent movement calculated by the control.
  • the sheet metal plate is brought back into the vertical position by rotating the pliers 34 and by moving the columns 15 on the rails 17 and by lifting the gripper slides 20 of the rotating device 105 fed. There, the metal sheet is held in place by the magnets 120, whereupon the pliers 34 are opened and the columns 15 are withdrawn to the left in FIG. 3.
  • the rotating device 105 is operated by actuating the motor 118, so that the metal sheet is rotated in the vertical plane.
  • the angle of rotation can be precisely set or programmed.

  • the sheet metal plate is brought into the horizontal position by rotating the pliers 34 and moved again by the required amount under the tool stamp.
  • the other bends run exactly the same as the first bend described. If a further bend in the same direction is required, the sheet metal plate is rotated about the axis of the two pliers 34.
  • the support beam 39 is brought into the position shown in FIG. 2B by pivoting the boom 40, so that the vertical columns 15 together with the gripper slide 20 can approach very close to the tool ram 1. This position is shown in broken lines in FIG. 2.
