Definitions

  • the invention relates to a method in the preamble of the first claim specified type and on a device for performing the method.
  • the folding of sheet metal is generally known and is usually done on presses carried out.
  • a bending rail is arranged in the upper tool (Formbacke) used, the sheet metal area to be bent near the bending line bends.
  • Sheet metal parts are bent with such a device, on which the mold jaw cannot bend evenly on the bending line, this will be bent Sheet metal part not evenly deformed or even deformed. Then they form Waves or bumps that can no longer be completely eliminated.
  • the same Disadvantages occur when due to the existing shape of the bevelled Sheet metal part with translationally movable mold jaws, these bending edges cannot run over far enough.
  • the object of the present invention is to remedy this and a method and to propose a device for carrying out the method which the aforementioned disadvantages are avoided.
  • FIGs 1 denotes a tool frame in a press, 2 a movable press lower tool and with 3 an associated, also movable Press punch.
  • a rotating body 4 is in a housing 5 in Cut visible.
  • the rotating body carries a shaped jaw 4.1. This serves Pick up and fold the sheet metal area to be bent.
  • a lever 6 is arranged on the rotating body 4 and cooperates with a slide 7.
  • the slide 7 is in slide guides 8 on the tool frame 1 guided.
  • the carriage 7 is actuated by a slave cylinder-piston arrangement 9 which is also attached to the tool frame 1.
  • the slave cylinder-piston unit 9 is actuated via a master cylinder-piston unit 10, which is attached to the tool frame 1. Are connected the two cylinder piston units via a hose connection 11.
  • a plunger 15 is provided in such a way that when the tool is closed the plunger 15 the piston rod 10.1 of the master cylinder-piston unit 10 straight touched without moving them.
  • FIG. 1 Also shown in FIG. 1 is a postforming stamp 12, which is also on the tool frame 1 is attached and cooperates with the rotating body 4 when it has reached its end position ( Figure 2).
  • the sheet to be further formed at the same time is also shown in FIG. 1 and designated with 13, the beveled already in a previous operation formed (deep-drawn) area is provided with the reference number 14.
  • the end position of the press is shown in FIG. Here was the chamfer Sheet metal region 14 by pivoting the rotary body 4 with the mold jaw 4.1 bent in the housing 5.
  • the upper tool moves 3 downwards until the sheet 13 between the upper tool 3 and the lower tool 2 is clamped. In this position the Ram 15 the piston rod 10.1 of the master cylinder-piston unit 10.
  • the end position is reached when the lower tool 2 on the tool frame 1 rests. In this position, the postform stamp 12 also bumps against the Rotating body 4 and locked it in the end position.
  • FIG 3 is a perspective view of the principle of the rotating body 4 in its Housing 5 shown. It can also be seen here that the rotating body 4 in its starting position is held by two springs 16 which laterally from the Protrude housing 5 and are attached to the housing 5 at a suitable location
  • the postform punch 12 penetrates the housing 5 and acts in the end position together with the stop surface 4.2 on the rotating body.
  • Figure 4 differs from the illustration in Figure 3 in that the left Half of the housing has broken away. This is one of the two side guide surfaces of the rotating body 4 visible.
  • the rotating body 4 points in this example first lateral guide surfaces 17, which are designed like a segment of a circle. It is in the housing via two correspondingly designed counter-guide surfaces 18 5 led.
  • the design of the two guide surfaces depends of course on the folding angle and the pivoting range of the rotating body 4 in its housing 5 from.
  • the housing 5 is omitted, so that the rotating body 4 with its guide surfaces 17 and 19 arranged on both sides is visible.
  • the design of the lever 6 depends on the lifting height of the slave cylinder-piston unit 9 and the folding angle.
  • Figure 7 shows a detail of the carriage 7 in the starting position. Here is visible how the carriage 7 is guided in the carriage guide 8 without play.
  • the Slide guide 8 guide surfaces 22 to 24.
  • Figure 8 shows the carriage in the end position, i.e. with the maximum extended Piston rod of the slave cylinder-piston unit 9.
