Definitions

  • the invention relates to a folding machine according to the preamble of claim 1.
  • the invention has for its object to provide a folding machine that allows a simple and safe way to join two sheets at right angles, from which a channel of rectangular cross section can then be made.
  • a folding machine has, as shown in FIG. 1, a machine frame 1 which is U-like in cross section, the yoke part 2 of which forms the foot of the machine frame.
  • the one, somewhat shorter leg 3 of the machine frame 1 extends vertically upwards and is widened in the region of its upper end to form a bearing surface 4.
  • the bearing surface 4 is inclined towards the other, somewhat longer leg 5, namely at an angle of approximately 20 ° with respect to the horizontal.
  • the leg 5 is angled at its upper end against the other leg 3 and also widened to form a support surface 6.
  • This, like the support surface 4, is of a flat design and extends perpendicular to the plane defined by the support surface 4. It therefore forms an angle of approximately 20 ° with the vertical.
  • an upwardly open U-rail 7 is attached to it slightly below the bearing surface 4 and, as shown in FIG. 2, projects beyond the two end faces of the leg 3.
  • a corresponding U-rail 8 is attached to the underside of the angled end portion of the leg 5 so that it also does not protrude into the plane defined by the support surface 6.
  • the U-rail 8 also projects beyond the two end faces of the leg 5.
  • the two U-rails 7 and 8 serve for the longitudinally adjustable accommodation of two clamping devices 9 and 10, by means of which the front and rear edges of the metal sheets can be gripped and clamped.
  • the clamping devices 9 which detect the front edge, that is to say the edge at which the folding process begins, have, as shown in FIGS.
  • a double-armed pivot lever 12 is pivotally mounted about an axis 13 lying transversely to the longitudinal direction of the U-rail and parallel to its yoke part.
  • two cheeks extend from the pivot lever 12 into a lateral recess in the base body 11, as shown in FIGS. 8 and 9.
  • the pivot lever 12 has a long arm 12 ', which at its free end rotates in a slot about an axis parallel to the axis 13 an eccentric 14 which rests on the top of the base body 11 and can be rotated by means of a hand lever 15.
  • the short arm 12 ⁇ of the pivot lever 12 points to the center of the machine and carries in a thread a clamping screw 16, between which and the roughened top of the base body 11, a sheet metal plate can be clamped. Thanks to the clamping screw 16, the clamping device 9 can be adapted to different panel thicknesses.
  • the base body 11 is provided with an upwardly open transverse groove 20, which is penetrated by a shaft 17 rotatably mounted in the U-rail, of which a displacement element 18 in the radial direction like the beard of a key protrudes.
  • the shaft 17 and the displacement element 18 can be pivoted by means of a lever 19.
  • the displacement element 18 rests on the one flank of the transverse groove 20 and therefore holds the clamping device 9 in the U-rail at one end of its displacement path. If the lever 19 is pivoted through 180 °, then the displacement element 18 comes into contact with the other flank of the transverse groove 20 and displaces the clamping device into its other end position.
  • the entire displacement path is chosen somewhat larger than the depth of the clamping mouth, which is formed by the short arm 12 'and the section of the base body 11 opposite it, so that the clamping device 9 by a pivoting movement of the lever 19 by 180 ° in a viewing direction according to FIG. 8 can be retracted counterclockwise to the extent that the edge of a metal sheet that has been overlapped is released.
  • the two clamping devices 10 which grip the rear edge of the metal sheets, must be displaceable over a greater distance in the U-rail because of the different lengths of the metal sheets. They are therefore not provided with the displacement device formed by the shaft 17 and the displacement element 18, but with a tensioning device which parallel the base body in the U-rail between the two Thighs tight. Otherwise, they are designed like the clamping devices 9.
  • a stop rail 21 is provided which runs parallel to the U-rails 7 and 8 and is carried by two pivot arms 22 which are pivotably mounted on the leg 5 with a horizontal pivot axis 23 parallel to the U-rails 7 and 8.
  • the stop rail 21 is open at the top, so that the sheet metal plate 39 resting on the support surface 6 can engage in it.
  • the stop rail 21 is pivoted downwards.
  • the end of the swivel arms 22 projecting beyond the outside of the leg 5 is swiveled upward.
  • a running rail 24 is fixed, which extends in the longitudinal direction of the channel delimited by the yoke part 2 and the legs 3 and 5 beyond the end faces of the machine frame 1, specifically in a dimension that is greater than the projection of the U-rails 7 and 8.
  • the upper part of the running rail 24 forms a double-T profile.
  • the running rail 24 carries a carriage designated as a whole as 25, which in turn carries a folding device 26. As shown in FIG. 3, wheels 27 of the carriage 25 engage between the transverse parts of the running rail 24, as a result of which the carriage is positively secured against displacement transverse to the longitudinal extension of the running rail 24.
  • a pinion 28 is arranged, which meshes with a toothed rack 29 provided on the underside of the upper transverse part of the running rail 24.
  • the pinion 28 is also driven by one in the carriage 25 arranged electric gear motor, which can be operated either in one or the other direction of rotation.
  • the pinion can be driven, for example, by a chain.
  • the cross-sectionally U-shaped carriage 25 carries, on a platform 30, from which the legs carrying the wheels 27 extend downward on both sides of the running rail 24, an elongated carrying device 31, which extends in the direction of travel of the carriage 25, for several, in pairs of folding rollers 32 arranged one behind the other in the direction of travel.
  • the carrying device 31 consists of a rod-shaped lower part 33 and a likewise rod-shaped upper part 34, which are connected to one another by a narrow web 35 which is inclined in accordance with the inclined position of the contact surface.
  • This web 35 runs in a wedge shape in its rear half, because here the edge zones of the two sheets to be connected have to be brought together.
  • the lower part 33 and the upper part 34 protrude beyond the web 35 in the dimensions required for receiving the folding roller pairs 32.
  • the web 35 is arranged between the second and third pair of folding rollers.
  • each pair of folding rollers 32 are, as shown in particular in FIG. 3, rotatably mounted on a bearing pin protruding from the upper part 34. Appropriate storage could also be provided for the lower folding rollers. In the exemplary embodiment, however, as is also shown in FIG. 3, they are each rotatably mounted in a U-type holder 36 which is connected to the lower part 33 in an adjustable manner. At least the folding rollers of the first pair of folding rollers 32 are slightly inclined, as shown in FIG. 7, around the metal sheet 38 transversely to the direction of travel of the carriage 25 against one on the machine frame 1 provided stop 37 to be pressed, so that it is ensured that the metal sheet 38 abuts the stop 37 during the folding process. Of course, it is also possible to tilt the axes of subsequent pairs of folding rollers 32 accordingly. As a rule, however, this will not be necessary.
  • metal sheets 38 and 39 which are at right angles to one another, are to be connected to one another along their one edge zone by folding, these two metal sheets 38 and 39 are placed on the support surfaces 4 and 6, as shown in FIG. 1.
  • the lower edge of the sheet metal plate 39 lies against the base of the stop rail 21.
  • the edge of the metal plate 38 facing the metal plate 39 has a line running parallel and at a distance from the edge lying in the stop rail 21.
  • the first of the pairs of folding rollers 32 carried by the carriage 25 initially deforms only the edge of the metal sheet 38 in the sense of a double offset, as shown in FIG. 10 above.
  • the second pair of folding rollers 32 forms a U-profile which is open at the bottom from this double cranked edge zone.
  • the third pair of folding rollers bends the edge zone of the metal sheet 39 inwards and the fourth pair of folding rollers presses the bent sheet metal strip upward, so that, as shown in FIG. 10, the long leg of the U-profile of the metal sheet 38 is taken up by the fold of the metal sheet 39. Now this fold is bent inwards by the fifth pair of folding rollers and, as shown in FIG. 10, is pressed into the depression by the sixth pair of folding rollers, which was initially formed by doubling the sheet metal plate 38.
  • the clamping devices 9 and 10 can be released. If, for example, a channel is to be formed from the two metal sheets 38 and 39, these metal sheets only need to be rotated about the longitudinal axis of the channel, which is much easier than the transport of the metal sheets. Furthermore, the metal sheets 38 and 39 need not be held in place during the folding operations. The operator therefore only needs to switch the drive motor of the carriage on and off for the folding processes.
