Definitions

  • the present invention relates generally to bending machines, that is to say machines capable of allowing the folding and / or rolling of any metal sheets.
  • Such folding machines have been known for a long time. They generally comprise a lower bed base, which is fixed, an upper bed base, which is mounted movable between a folded closed position, for which, with the lower bed base, it cooperates in maintaining a sheet of metal to be worked, and a deployed opening position, for which it leaves free access to said lower bed base, and a rotary apron, which is adjacent to the lower bed base, along a rectilinear working line, and which is pivotally mounted around said working line.
  • the rotary apron In the standby position, the rotary apron extends in line with the lower bed base; in service, it makes, by tilting, a dihedral, straight or arbitrary, with this box spring.
  • the rotary apron is tilted from its standby position to a service position for which it forces the sheet to work to take the desired configuration by deformation.
  • the locking means used are of the cam type, the upper base being provided with hooks which gradually come to engage in fixed handles by jointly developing a clamping effect, when the upper bed base is in the closed position.
  • the clamping force provided by the toggle locking means advantageously only depends on the configuration of the latter after they have crossed their maximum resistance line.
  • this clamping force does not depend on the force deployed by the operator, to the extent of course that this force was sufficient to cross the line of maximum resistance.
  • the present invention relates to a folder free of this drawback and also having other advantages.
  • This folder is the kind with a som mier lower, which is fixed, an upper bed, which is mounted movable between a folded closed position, for which with the lower bed, it cooperates in maintaining a sheet of metal to be worked, and a deployed open position, for which it leaves free access to said lower bed, a rotary apron, which is adjacent to the lower bed, along a straight working line, and which is pivotally mounted around said working line, and disengageable locking means of the type knee brace capable of coupling the upper base to the lower base for the closed position of said upper base, said toggle locking means comprising, for each end of said upper base, a connecting rod, which is articulated to the upper base, and a connecting rod, which is articulated to said connecting rod and to the lower base, and is characterized in that said connecting rod is constituted by a removable flange, and in that said removable flange comprises, on the one hand, a first hole called upper hole, by which it is rotatably engaged on a cylindrical bar carried by the upper base, and
  • the lower base 10 of the folder according to the invention which is fixed, is constituted by a section of U-shaped beam, the middle part 11 of which is horizontal and forms a work table, and whose lateral wings 12 are directed downwards, FIGS. 2A and 3 to 7.
  • the middle part 11 of this beam has longitudinally, from place to place, at a distance from its lateral wings 12, passages or housings 13.
  • two lateral cheeks 14A, 14B are attached vertically, for example by welding.
  • the lower base 10 is associated with an upper base 16 which, in general, is mounted movable between a folded closed position, represented in FIGS. 1 and 3, for which, with the lower base 10, it cooperates in the maintenance of 'a sheet of metal 17 to work, as described in more detail below, and a deployed open position, shown in FIG. 4, for which it leaves free access to the lower base 10.
  • the upper base 16 is formed by an angle iron, one wing 18 of which has its beveled edge 19, for cooperation with the lower base 10, and the other wing 20 of which is secured at its ends, for example by welding, to two links 21A, 21B each articulated respectively by studs 22A, 22B to the side cheeks 14A, 14B.
  • a rotary apron 24 which, in general, is adjacent to the lower bed 10, along a rectilinear working line, and which is pivotally mounted around this working line.
  • this rotary apron is constituted by an angle whose wing 25 extends in the extension of the lower bed 10 for the standby position of this rotary apron shown in solid line in fig. 3, and the other wing 26 of which, for this standby position, is in contact with the corresponding wing 12 of said lower bed base 10.
  • the lower base 10 and the rotary apron 24 thus have two rectilinear edges in contact with one another, and it is these edges which define the rectilinear working line mentioned above.

  • pins 28A, 28B are pivotally engaged in passages provided for this purpose in a complementary manner in the side cheeks 14A, 14B.
  • a handle 32 is attached, for example by welding, to the wing 26 of the rotary apron 24.
  • Releasable locking means of the toggle type are provided between the upper base 16 and the lower base 10 to couple the lower base 10 the upper base 16 in the closed position thereof.
  • these toggle locking means comprise, for each of the ends of the upper base 16, beyond the corresponding side cheek 14A, 14B, a removable flange 33A, 33B, which is articulated to the upper base 16, according to a first articulation axis A1, FIGS. 2A, 2B and 3, and a link 34A, 34B, which is articulated to said flange 33A, 33B, along a second articulation axis A2, parallel to the previous one, and to the lower bed base 10, and more precisely to the corresponding side cheek 14A, 14B, along a third axis of articulation A3, parallel to the previous two.

'from one another, and produced by welding, and spacers being established from place to place between this cylindrical bar 38 and the upper base 16, in a manner known per se for a long time.
  • three spacers 44 are thus provided, and each consists of a single screw, which is screwed into a threaded bore of the bar 38, and which bears on the wing 20 of the upper base 16, fig. 3.
  • the side cheek 14B protrudes from two protruding studs 46, 47, for defining the opening and closing positions of the upper bed base 16, and, for allow the operation thereof, an operating rod 48 is attached, for example by welding, on the rod 34B.

  • the upper base 16 is then tilted to the closed position, according to the arrow F in FIG. 4.
  • pins are apart from the center line of the rule 50, for adaptation thereof to rods or mandrels 49 of different diameters, by simple turning.
  • the flanges 33A, 33B are removed, and, depending on the diameter of the rod or mandrel 49 used, a choice is made between the distances d 'articulation D'1, D "1 suitable for offsetting the effects of this difference.

  • the internal wall 77 of the upper base 16 itself comprises a passage 84, but this has a diameter less than that of the head 80 of a screw 79, so that this head 80 is thus able to bear on this internal wall 77.
  • the lower base 10 itself comprises a passage 85, and it is the same for the wedge 50 usually implemented for a hemmer work.
  • the nut 81 participating in the constitution of a tie rod 78 is carried by a lever 87 articulated to the lower base 10, in the internal volume thereof, along an axis of articulation A4 parallel to the previously mentioned axes of articulation A1, A2, A3.
