Definitions
- Device for manufacturing panels with three-dimensional curvature from sheet material for example for thermoforming webs from thermoplastic material, and one-piece web thus produced
- the present invention relates to the manufacture of three-dimensionally curved panels from sheet material. It may, for example, but not exclusively, be the manufacture by thermoforming of webs with three-dimensional curvature from a thermoplastic sheet material.
- the invention also relates to a one-piece sail thus manufactured.
- sails for sailing boats which must have a three-dimensional curvature to be effective (to "take the wind"), are manufactured by stitching together several panels of fabric cut in such a way that their assembly allows obtain a sail with three-dimensional curvature.
- Document EP-056 657-A also discloses a one-piece sail with three-dimensional curvature consisting of a single piece of flexible thermoplastic sheet material, optionally reinforced with fibers of thermoplastic polymers.
- the veil manufacturing process as described consists in holding on its edges a continuous sheet of thermoplastic material possibly reinforced with thermoplastic polymer fibers, in heating the sheet, in apply pressure to the heated sheet to selectively stretch and cool it. It is specified without further details that the drawing of the sheet material by application of pressure is carried out on a mold or a curved shape, therefore on a convex mold surface.
- 01/00487-A sails made of laminated materials produced on a convex mold surface, either by successive deposition of a first flexible sheet, of continuous threads and of a second flexible sheet and by stratification of the assembly on the surface of mold, either by successive deposition of two layers each formed from several panels of sheet reinforced with threads, with offset of the edges of the panels of the two layers, and by stratification of the assembly on the mold surface.
- the mold surface whose shape corresponds to the shape of the sail to be produced is defined by several rows of profiled elements mounted on parallel flexible slats each supported along its length by several adjustable columns in height supported by crosspieces of a support frame.
- the present invention relates generally to a device for manufacturing panels with three-dimensional curvature from sheet material and more particularly, but not exclusively, to a device for manufacturing sails with three-dimensional curvature, for example one-piece sails intended for light craft. and in particular of the general public type, this device making it possible to manufacture panels with three-dimensional curvature and more particularly sails at a reduced cost price, without high labor costs.
- the invention further relates to a device for manufacturing panels with three-dimensional curvature which is simple in structure and flexible in use, making it possible to move quickly and without complicated and long transformation works to the manufacture of panels of different shapes and sizes.
- the invention also relates to a one-piece sail thus manufactured.
- the device object of the present invention intended for the manufacture of panels with three-dimensional curvature from sheet material, comprises a forming imprint defined by a membrane comprising an elastically stretchable skin and a network of means for selective deformation of the imprint acting on said membrane to impart a modular three-dimensional curvature to the forming imprint.
- the membrane may further comprise a skeleton associated with the skin, formed by a network of elastic slats in flexion which are movable in longitudinal translation with respect to each other and with respect to the skin with which this skeleton is associated. without affecting the surface of the skin defining the forming imprint.
- the slats are slidably mounted in flexible sheaths, preferably elastically stretchable, integral with the skin of the membrane, preferably embedded by overmolding in the skin. These sheaths thus participate in the deformation of the skin without upsetting it.
- the means of deformation of the membrane can be designed so that the curvature imparted to the latter is convex and / or concave, therefore in relief and / or in hollow relative to the sheet material placed at the - above the membrane.
- the membrane is traversed by a network of suction openings connected to vacuum means below the membrane.
- the depression thus produced between the membrane and the sheet material allows this material to tackle on the membrane and faithfully adopt the curvature of the latter.
- the membrane deformation means are designed to give the membrane a concave curvature
- the sheet material is a thermoplastic material
- the provision of the suction openings passing through the membrane makes it possible to deform the sheet material by subjecting it to a variable stretching as a function of the depth of the imprint.
- the degree of stretching of the sheet increases from the edges towards the center of the sheet, and the panel cut from the sheet material thus formed has a variable thickness in accordance with the stress zones. , namely a thickness and therefore greater resistance at the edges and at the angles than in the central part. This is particularly advantageous in the case of a sail which may preferably be a one-piece sail.
- the membrane may advantageously, on the face constituting the forming imprint, either have a rough surface state, for example grainy, or be covered with a layer of a material permeable to gases, for example a porous material or the like, improving the air circulation between the suction openings, in order to avoid any trapping of air between the membrane and the sheet.
- FIG. 1 is a schematic top view of a mode production of a device according to the invention in its application to the manufacture of a sail shaped by thermoforming
- Figure 2 is a schematic section of the device of Figure 1 during the thermoforming phase
- Figure 3 is a corresponding schematic section of the device during the cutting phase
- Figure 4 is a partial view of the membrane of the device of Figures 1 to 3
- Figure 5 is a partial section of the membrane showing the sheathed slats embedded in the skin of the membrane
- Figure 6 is a simplified schematic view showing a mode of action of the diaphragm deformation cylinders.
- the manufacture of a one-piece sail 1 with three-dimensional curvature as illustrated in dashes in FIG. 1 is carried out by vacuum thermoforming and cutting, from a mold 2 with variable geometry, of a material sheet thermoplastic
- the mold 2 comprises a forming imprint 5 defined by a membrane 6 made of an elastically stretchable and heat-resistant material, placed on the mold 2, means 7 for the selective deformation of the imprint 5, and a frame 8 for holding on its periphery the sheet material 3 placed above the membrane 6. Above the mold 2 are arranged means 9 for heating the sheet material 3.
- the membrane 6 comprises a skeleton formed by a grid of elastic slats 10 in bending, for example made of carbon fibers, and a skin 11 made of an elastically stretchable material, for example a silicone-based elastomer.
- the slats 10 are surrounded by flexible sheaths 12 (FIG. 5) in which they can slide longitudinally and which are embedded by overmolding in the skin 11.
- the skin 11 is traversed right through a network of suction openings 13 connected below the membrane 6 by flexible pipes 14 to vacuum means 15 comprising in the example illustrated according to FIGS. 2 and 3 , a valve 15a, a reservoir-accumulator 15b and a vacuum pump 15c.
- the skin 11 of the membrane 6 is covered, according to FIG. 5, with a thin layer 16 of a material permeable to gases, for example a porous material such as a foam.
- heating means 9 may include a panel heating, for example with infrared radiation, covering here the entire surface of the imprint 5, or any other suitable device.
- the heating means 9 are for example horizontally movable, which allows, after thermoforming and cooling of the sheet material 3 on the imprint 5, their removal for the establishment for example of a device 17 for cutting the contour of the veil 1 in the thermoformed and cooled sheet material 3 '.
- the cutting device 17 may for example comprise a head 18 with a cutting blade, a heating blade, a water jet or preferably a laser, selectively displaceable over the entire surface of the mold 2 and optionally in height so as to remain at a constant height of the imprint 5 by a command which can be linked to the control of the jacks 7, so as not to damage the membrane 6.
- thermoformed sheet material 3 instead of cutting the thermoformed sheet material 3 directly on the imprint 5, it is also possible to trace the thermoformed sheet material 3 on the imprint 5 and cutting at another station by optical marking of the tracing line.
- the cylinders 7 for the selective deformation of the membrane can preferably act on the slats 10 which here have a circular section instead of a rectangular section according to Figures 4 and 5. More specifically, each cylinder 7 acts on a cross 17 which is crossed by two slats 10 at the point of intersection of these slats.
- the sheaths not shown here of the slats 10 can either cross the spider 17 with the slats, or be interrupted at the location of the spider 17.
- the spider is embedded in the skin not shown here of the membrane, just like the part remaining of the skeleton formed by the grid of slats 10.
- the cross-pieces 17 allow the slats 10 to follow the vertical movements of the jacks 7, when the latter are shortened and lengthened, while leaving them the possibility of sliding in the direction of their length relative to the skin.
- the jacks 7 can advantageously be connected in an articulated manner, by example by a ball-type connection 19 or a flexible connection, to the cross-pieces 17 and possibly also to their anchoring support.
- sail reinforcements can be glued and placed in the mold to be glued to the sail during the thermoforming of the latter, which allows take advantage of the vacuum and the heat of the thermoforming phase to tackle these parts and to facilitate the polymerization of the glue, while reducing the labor cost.
- the embodiment illustrated and described relates to thermoforming, on a concave mold imprint (hollow), of a one-piece sail, the invention is not limited to this embodiment and on the contrary encompasses not only thermoforming on a convex mold imprint (in relief), but also all combinations of these two variants (curvature inverted sails).
- thermoforming of the sheet material can be done not only by vacuum, as in the example illustrated, but also by pressure or by a combination of the two.
- the sheet material 3 instead of being in one piece, could also include several panels assembled either in advance or during shaping.
- thermoplastic sheet material may consist of a film or of a complex of several films, for example PET, preferably bi-oriented ("MYLAR"), PVC, polycarbonate, which can be armed with fibers. They may in particular be continuous fibers (filaments) with high breaking strength which are not thermoplastic, for example carbon or ara ide fibers.
- thermoforming by stretching the film or thermoplastic complex despite the presence of these fibers
- a sheet material which is devoid of fibers in the region of its periphery, therefore at the clamping frame 8 This avoids blockage of the fibers by the frame 8 and allows the fibers to slide relative to the sheet material during thermoforming, the glue possibly provided for bonding the sheet or sheets and the fibers being softened by the heat applied for thermoforming.
- the present invention also relates to a one-piece web formed of a thermoplastic material in the form of at least one continuous sheet reinforced with continuous fibers (filaments) of non-thermoplastic material such as carbon fibers or aramid , this sheet having a permanent three-dimensional curvature obtained by thermoforming.
- the invention applies generally to the manufacture of panels with three-dimensional curvature with low shape development (of reduced depth) from sheet materials which may or may not be thermoplastic.
- sheet materials which may or may not be thermoplastic.
- it may, among other things, be body parts, for example made of thermosetting materials.
- the slats constituting the skeleton of the membrane are in the form of a grid, therefore of a bi-directional network, these slats may, in the context of the present invention , be in the form of different networks, for example a mono-directional network or also any other multi-directional network.
- the membrane may be sufficient to constitute the membrane only by an elastically stretchable skin, therefore without the network of slats forming a skeleton, and in this case to act the jacks or other means. deformation of the forming imprint directly on the skin rather than on the slats or on the braces or other rigid guides traversed by the slats and embedded in the skin of the membrane provided with a skeleton. In all cases, it is advantageous to connect the jacks to the membrane by an articulated connection, for example of the ball joint type.
- the frame 8 which serves to hold the sheet material during thermoforming can be replaced by frames of reduced size, not shown, adapted to the size and the shape of the panels.
- the mold 2 can advantageously be equipped with means for cooling the sheet material 3 after thermoforming, such as a fan or other means known per se, for example a network. water circulation in the mold (in the membrane).
