Definitions

  • the present invention relates to a flat folding tool, that is to say of the type comprising a fixed blade having a horizontal surface, one edge of which constitutes the folding line, and an assembly movable in the direction of the above-mentioned horizontal surface of the fixed blade and comprising, essentially, a blank holder linked elastically to the mobile assembly and adapted to be applied against the sheet previously placed against the horizontal surface of the fixed blade to ensure its maintenance before the start of the stroke fraction of the movable assembly corresponding to the folding and a movable blade intended to be moved transversely along the edge of the horizontal surface of the fixed blade along which the folding is carried out.
  • the present invention aims to remedy this drawback.
  • the movable blade in which each blade has, on its lateral face opposite the other blade at the end of the transverse stroke of the movable blade, a release step, the movable blade is pivotally mounted about an axis parallel to the fold line and means are provided to cause the pivoting of the movable blade towards the fixed blade after it has reached its end. transverse stroke and thus allow the continued folding of the sheet at an angle less than 90 °, this folding angle being determined by the value of the translational and / or rotational travel of the movable blade.
  • This arrangement makes it possible to provide a clearance between the blades much greater than the thickness of the sheet to be folded and consequently to reduce the effort necessary for folding a sheet.
  • the movable blade is carried by a movable support or blade holder to which it is articulated and which is slidably mounted in the sheath-shaped body of the movable assembly, between two positions extremes, elastic means tending to move this support in the direction of the fixed blade, at least until the start of the pivoting stroke of the movable blade and the means for causing it to pivot consist of an inclined plane forming a ramp provided along from the free edge of the lateral face of the movable blade opposite to that opposite with the fixed blade and by a complementary tilt shoe carried by the body of the mobile assembly and against which the aforementioned ramp is held in abutment by means spring-loaded and so that the continuation of the movement of the movable assembly, after the movable blade and its support have themselves reached their end of travel, causes the pivoting of the movable blade as a result of the sliding d u aforementioned shoe on the ramp of the movable blade.
  • the elastic means acting on the movable blade holder to move it in the direction of its end position closest to the fixed blade consist of a plurality of single-acting cylinders, the piston rods of which bear against the rear face of the blade holder and whose cylinders, carried by the body of the movable assembly, are supplied with fluid under adjustable pressure by the setting of a relief valve.
  • the discharge valve is a piloted valve whose opening is controlled by means for detecting the end of travel of the movable blade holder.
  • This provision has the advantage of reducing the energy consumption during the stroke of the movable assembly corresponding to the pivoting of the movable blade, by removing the pressure in the aforementioned jacks, the action of which would otherwise tend to oppose this stroke.
  • the elastic means acting on the blank holder are constituted by a plurality of single-acting cylinders whose piston rods, which freely pass through the movable blade holder, are supported on the rear face of the blank holder and whose cylinders, carried by the body of the mobile assembly, are supplied with fluid under a pressure the maximum value of which is determined by the calibration of a relief valve, shouldered screws freely passing through the blade holder constituting the end stops in the rest position of the blank holder.
  • the flat folding tool according to the invention essentially comprises a fixed blade (2) and a movable blade (3).
  • the fixed blade (2) is located below the movable blade (3) and its upper horizontal face (2a) is intended to receive and support the sheet to be folded (4) before the start of the operation. folding.
  • This fixed blade (2) is fixed to a support (5) capable of being itself fixed to the table of a press brake or similar.
  • the movable assembly (6) of this folding tool comprising, inter alia, the movable blade (3).
  • This movable assembly can in particular be fixed, for example, by a tenon (7) or movable slide of the press brake to the table from which the support (5) of the fixed blade (2) is fixed.
  • the fixed blade (2) has below its working edge (2b), that is to say in its lateral face (2c), facing the trajectory of the movable blade (3), a step (7) allowing the release of the sheet (4) when the folding angle is less than 90 °.
  • the movable blade (3) has above its working edge (3a), that is to say in its lateral face (3b) facing the fixed blade (2), a step ( 8) allowing it to execute a bending of the sheet (4) at an angle less than 90 °.
  • the movable blade (3) is carried by a support or blade holder (9) slidably mounted in a direction perpendicular to the surface ( 2a) of the fixed blade (2) in the sheath-shaped body (6a) of the mobile assembly (6) and to which the mobile blade (3) is articulated along an axis (11) parallel to the defined fold line by the working edge (2b) of the fixed blade (2).
  • the upper edge of the lateral face (3b) of the movable blade (3) has a rib (12) of partially cylindrical cross section accommodating in a cradle (13) of complementary section formed in the support (9).
  • this mounting of the movable blade (3) in its support (9) allows it to pivot in the direction of the arrow (14) between two extreme positions, that is to say a rest position as illustrated in FIGS. 1 to 3 and a position for continuing folding as illustrated in FIG. 4.
  • the blade holder (9) was mounted in the body (6a) of the movable assembly (6) so that it can slide in a direction perpendicular to the horizontal surface (2a) of the fixed blade ( 2), that is to say in the vertical directions illustrated by the arrows (16) and (17). This sliding of the blade holder (9) is limited to two extreme positions, namely a low or extended position as illustrated in FIGS. 1 to 3 and a high or retracted position as illustrated in FIG. 4.
  • Means are provided to act on the blade holder (9) and tend to maintain it normally in its low or extended position.
  • these means are constituted by a plurality of cylinders whose free end (18) of the piston rod (19) is applied on the upper face of the blade holder (9) and whose cylinder (21) is housed in the body (6a) of the mobile assembly (6), the seal being ensured by O-rings (22) and (23).
  • the cylinders (21) of these jacks are normally subjected to the pressure of a pressurized fluid supplied by the channel (24) from a pump not shown in the drawing and through a non-return valve (25).
  • a relief valve (26) limits the pressure in the cylinder (21) to the desired value.
  • the means of limiting the stroke of the blade holder (9) to its low or extended position in which it is normally held by the piston rods (19) can be produced in any suitable manner by shouldered screws passing freely through it and anchored in the bottom of the body (6a) of the movable assembly (6).
  • the mobile assembly (6) also comprises a blank holder (33) movable vertically between two extreme positions, the lower one illustrated in FIG. 1 in which its upper face is distant from the lower face of the blade holder (9) and in which it is retained by shouldered screws (34) freely passing through the blade holder (9), and a high position in which its lower face is applied against the sheet to be folded (4) and its upper face is pressed against the underside of the blade holder (9) to which it serves as a limit stop.
  • Means are provided for acting elastically on the blank holder (33) and normally tend to keep it in the low position as illustrated in FIG. 1. According to a simple embodiment of the invention, as illustrated in the drawing and in particular visible in FIGS.
  • these means consist of piston rods (27) freely passing through the blade holder (9), the lower end of which bears against the upper face of the blank holder ( 33) and the cylinder (28) of which is supplied by a channel (29) and through a non-return valve (31) with pressurized fluid from a pump not shown in the drawing and the maximum pressure of which is limited by a valve discharge (32) whose calibration is adjustable to the desired value.
  • this folding tool is as follows: the assembly being at rest, as illustrated in FIG. 1, the sheet (4) to be folded is placed on the upper horizontal face (2a) of the fixed blade (2) of so that the fold line coincides with the edge of work (2b) of the fixed blade (2).
  • the descent in the direction of the arrow (17) of the movable assembly (6) is controlled, for example, by the action of the movable slide of a press brake on which this tool is mounted.
  • the blank holder (33) enters the first in contact with the sheet (4), the lower edge of the movable blade (3) being, as is known, offset behind the free edge, to the working face of the holder blank (33).
  • the descent of the mobile assembly (6) being continued while the blank holder (33) is stopped by the sheet (4) and the fixed blade (2), the piston rods (27) acting on it are stopped and the pressurized fluid of the jacks (28) is discharged through the discharge valve (32) whose calibration determines the tightening stroke of the sheet (4) against the fixed blade (2).
  • the pressurized fluid supplying the jacks (21) and (28) automatically return the blade holder (9) and the clamp -flan (33) in the rest position.
  • the relief valve (26) could be a pilot valve.
  • This arrangement has the advantage of making it possible to eliminate the pressure prevailing in the jacks (21) as soon as the lower face of the blade holder (9) has come into contact with the upper face of the blank holder (33). It suffices to provide means for detecting this contact. As a result, during the third fraction of the downward stroke of the movable assembly (6), the energy required for rolling the pressurized fluid contained in the cylinders (21) is saved.
