Definitions

  • the present invention relates to a machine for the formation of sheet metal panels and, more particularly, to the realization of the folds required for the application plates using means that make the work of this function particularly advantageous.
  • Machines which automatically perform the bending of sheets, according to predetermined angles, said machines comprising a punch and a die, between which is formed the forming of the sheets by folding, this operation being carried out by progressive bending, for compensate for the recovery capacity of folded sheets which varies according to various factors, such as the nature of the material, the size, etc.
  • the precision of the folding also requires exact control of the angle obtained, and for this purpose measurement systems associated with the folding process, consisting of a laser measuring instrument, are used in complex devices integrated with the punch. folding or independent portable devices, the systems in question proving complicated and expensive.
  • the present invention relates to a machine which includes means for making the fold and a device for measuring the angle of the folded sheet, different in their design of the known systems and offering certain advantages for the practical function of the bending of the metal sheets. 'application.
  • the document JP-A-07 275 952 describes a panel with means for measuring the bending angle of the sheets.
  • the measuring head has two feelers that can be moved in the vertical direction by means of a jack. These feelers are brought into contact with the folded sheets by means of a slider.
  • the machine forming the subject of the present invention comprises a folding mechanism composed of a movable blade holder situated opposite a device for holding and immobilizing the sheets to be bent, the immobilizing device comprising a fixed lower part or counter blade and an upper plate clamp actuated vertically by means of a push cylinder, while the blade holder is provided with a probe disposed on a displacement cylinder which leads it to the plate immobilizer device.
  • the blade holder is incorporated in a translation device which ensures its displacement towards the plate immobilizer and to an articulated tilting device which makes it possible to vary its position vertically with respect to the plate immobilizer, the two movements being ensured by the two drive cylinders.
  • the panel is designed to bring the probe into a first measurement position in contact with the folded sheets by means of the displacement cylinder and then to bring the probe into a second measurement position in contact with the end zone of the folded part of the plates at the means of the tilting device of the blade holder,
  • the plate clamp of the sheet immobilizer is disposed on a carriage driven by the push cylinder, the blank holder in question consisting of a assembly formed of two end blocks and a central block which determine a continuous longitudinal shape, the central block can be replaced to modulate the longitudinal dimension of the assembly as a function of the width of the application plates.
  • the blade carrier includes a carriage capable of automatically conveying the central block of the blank holder from the mounting position to a magazine containing a plurality of blocks of different lengths, to allow the selective replacement of the block in question in the longitudinal adaptation of the blank holder, the replacement carriage being driven by a jack independent or associated with that of the probe also incorporated in the blade holder.
  • a functional group is thus obtained which makes it possible to quickly and accurately fold sheets at predetermined angles, by automatically controlling the angle of folding to determine the corrections necessary for the operation. .
  • the functional assembly can adapt to sheets of different widths, thanks to the automatic selective change in the length of the holding blank, which makes it possible to obtain a high speed in the operating operational arrangement. compared to the application plates.
  • the invention relates to a panel for automatically performing the folding of sheets (1), according to the folds required for the formation of door panels, partitions or similar applications.
  • the machine has a folding mechanism which comprises a blade holder (2) disposed in a movable configuration facing an immobilization device for the sheets (1) to be folded.
  • the immobilizing device comprises a lower part (3) or counter-blade fixed on the structural frame (4) of the machine and an upper blank holder (5) capable of being driven vertically in abutment against the lower part (3). ) above to immobilize between the one and the other part the sheets (1) of application to be able to perform the folding operations.
  • the blade holder (2) is arranged in vertical tilting articulation on carrying trolleys (6) mounted on slides which lead them to the plate immobilizer (1).
  • the carriages (6) are connected to the respective cylinders (7) which allow them to advance and retreat while the blade carrier (2) is connected to one or more cylinders (8) which ensure the vertical tilting of the blade carrier ( 2) relative to the articulation provided on the carrier trolleys (6).
  • the blade holder (2) is equipped with a feeler (9) arranged on a jack (10) which leads it to the front part where the immobilizing device of the sheets (1) is located.
  • the sheet (1) to be folded is retained by means of the immobilizing device between the blank holder (5) and the fixed part (3), as illustrated in FIG. figure 3A , so that when the sheet is found in this position, the movement of the blade holder (2) driven by the cylinders (7 and 8) causes folding of the end of the sheet (1) immobilized, as shown on the figure 3B .
  • the blade holder is driven automatically by the cylinders (7 and 8) according to the bending angle programmed in the control of the machine, the bending of the sheet being effected during a first operation according to the programmed angle , without exceeding this angle, after which the blade holder (2) returns to the starting position, as illustrated in FIG. figure 3C .
  • the cylinder (10) then drives the probe (9) and leads it to the folding zone of the plate (1), as illustrated in FIG. 3D figure ; then, by the necessary tilting of the blade holder (2), the feeler (9) is brought into contact with the end zone of the folded portion of the sheet (1), as illustrated in FIG. figure 3E .
  • the blank holder (5) is arranged on a carriage (11) articulated on the structural frame (4) of the machine, the carriage (11) in question being tilted by the jack (12), the same jack exerts a pressing against the plates (1) to immobilize them by bringing the blank holder (5) against the fixed lower part (3).
  • the blank holder (5) consists of two end blocks and a central block which determine the length of the blank holder body (5), the central block being replaceable by blocks of different lengths, which allows to adapt the length of the entire blank holder (5) according to the width of the sheets (1) application so that the operation of the machine is as accurate as possible in each case.
  • the blade holder (2) is equipped with a carriage (13) which makes it possible to automatically replace the central block of the blank holder (5) as a function of the width of the sheets (1) to be folded with the machine in each case, so that the carriage (13) moves and grasps the central block of the blank holder (5) as it passes to a magazine (not shown) containing a plurality of similar blocks of different lengths, where the trolley (13) takes the block of appropriate length, then takes it to the blank holder (5) and places it in the center of it.
  • the carriage (13) is driven by a jack (14) controlled by the control of the machine, said jack (14) being an independent jack, serving only to move the carriage (13); but it is also possible to use for this function the cylinder (10) of the probe (9), in which case the carriage (13) would be associated with said cylinder (10) relative to the corresponding control to perform this function of changing the central block of the blank holder (5).
