Definitions

  • the invention relates to a device according to the preamble of the first claim (see, for example DE-C-940525 ).
  • a bending jaw (shaping jaw) arranged in the upper tool is used, which bends the sheet metal area to be bent near the bending line.
  • Object of the present invention is to remedy this situation and to propose a method and an apparatus for performing the method by which the aforementioned disadvantages are avoided.
  • the mold jaw is pivotally guided in a housing.
  • a fold can be made evenly at the bend line.
  • already hereby converted sheet metal areas can be folded, which would otherwise be deformed in a translational movement of the mold jaw. This makes it possible to produce sheets, e.g. in automobile body construction, reshape, in which previously occurred at the bending bumps or waves that could not be removed or only very labor intensive.
  • FIG. 1 the arrangement according to the invention is shown schematically in its initial position, i. before the beginning of the bending process with the tool still open.
  • 1 denotes a tool frame in a press, with 2 a movable press lower tool and with 3 an associated, also movable press upper tool.
  • a rotary body 4 in a housing 5 is visible in section.
  • the rotation body carries a mold jaw 4.1. This serves to accommodate the bent sheet metal area andgravkanten.
  • a lever 6 On the rotary body 4, a lever 6 is arranged, which cooperates with a carriage 7.
  • the carriage 7 is guided in slide guides 8 on the tool frame 1.
  • the carriage 7 is actuated by a slave cylinder piston arrangement 9, which is likewise fastened to the tool frame 1.
  • the two cylinder-piston units are connected via a hose connection 11.
  • a plunger 15 is provided on the press upper tool 3 in such a way that when the tool is closed, the plunger 15, the piston rod 10.1 of the donor cylinder piston unit 10 just touched, without them to move.
  • a Nachformstempel 12 which is also attached to the tool frame 1 and cooperates with the rotary body 4 when it has reached its end position ( Figure 2).
  • the sheet metal which is to be further shaped at the same time is also shown in FIG. 1 and denoted by 13, wherein the region (deep-drawn) which has already been folded in a previous operation is designated by the reference numeral 14.
  • the upper tool 3 moves downwards and that until the sheet 13 is clamped between the upper tool 3 and the lower tool 2. In this position, the plunger 15 contacts the piston rod 10.1 of the master cylinder piston unit 10th
  • the end position is reached when the lower tool 2 rests on the tool frame 1. In this position, the Nachformstempel 12 abuts against the rotary body 4 and locks it in the final position.
  • this is achieved by choosing a suitable transmission ratio between on the one hand between master and slave piston cylinder unit and on the other by the working paths of the carriage 7 and the press upper and lower tool (3 or 2).
  • FIG. 3 shows a perspective basic view of the rotary body 4 in its housing 5. Furthermore, it is visible here that the rotary body 4 is held in its initial position by two springs 16 which protrude laterally from the housing 5 and are fastened at a suitable location on the housing 5
  • the Nachformstempel 12 penetrates the housing 5 and cooperates in the end position with the stop surface 4.2 on the rotary body.
  • FIG. 4 differs from the illustration in FIG. 3 in that the left-hand half of the housing is broken away. Thus, one of the two lateral guide surfaces of the rotary body 4 is visible.
  • the rotary body 4 has in this example first lateral guide surfaces 17, which are formed like a circle segment. It is guided via two correspondingly configured counter guide surfaces 18 in the housing 5.
  • the design of the two guide surfaces depends on the bending angle and the pivoting range of the rotary body 4 in its housing 5.
  • the design of the lever 6 depends on the lifting height of the slave cylinder piston unit 9 and the bending angle.
  • the contour of the tread for the roller 21 on the lever 6 is further designed so that after completion of the bending process, the carriage 7 can move on without further movement of the rotating body 4. This comes in a further downward movement of the press lower tool 2 of the Nachformstkov 12 with the contact surface 4.2 of the rotating body in contact.
  • FIG. 7 shows a detail of the carriage 7 in the starting position. Here it is visible how the carriage 7 is guided in the slide guide 8 without play.
  • the carriage guide 8 guide surfaces 22 to 24.
  • Figure 8 shows the carriage in the final position, i. at maximum retracted piston rod of the slave cylinder piston unit 9th
