    MACHINE FOR THE PRODUCTION OF CIRCULAR PRODUCTS THROUGH LAYER-BY-LAYER ADDITION. The invention relates to a machine for the production of layer by layer of objects, comprising: a circular rotating container arranged at the bottom (B), its interior equipped with vertically motorized cylindrical crowns independently (7) and a stationary part that covers the top of the container. The machine also includes at least one production unit comprising a first station (1) for the distribution of the product layer, a second station (2) for balancing the thickness of the layer, a third station (3) for controlling and regulate the temperature of the next layer, a fourth station (4) to solidify the useful surfaces of the product layer, a fifth station (5) to control and regulate the temperature of the layer, which has just been deposited, and a sixth station (6 ) for the treatment and impregnation of the layer.

    专利说明:

    [0001] The difficulty found in today's layer-by-layer powder sintering machines is their low capacity, due to the alternating linear sweeping of the work area, which is a disadvantage because the back and forth movements take a considerable time, which is harmful for circular pieces with a large diameter, and also because the cooling of the pieces produced in containers is very time-consuming.
    [0002] The temperature of the deposited layers is practically not controlled or regulated continuously, which requires a certain amount of time to cool down before it is possible to apply new layers, as well as to maintain them after removing the finished parts from the container.
    [0003] The principle of construction by stacking layer by layer is natural and has been used since the beginning of time for the construction of buildings, even before the Egyptian pyramids.
    [0004] It is now possible to build products with very complex helical shapes with increasingly thinner layers, which were never possible before to manufacture with the tools of the time, due to the accumulated technical progress made simultaneously in all fields: - the precision of mechanical construction , - polymerization of resin, laser sintering powder, cutting of thin sheets, and the addition of material, - the performance of computer hardware added to that of software packages, - the possibilities of sending files over the Internet, - the machines that manufacture successive layers directly using the received files, - as well as the CARPYZ computer tool itself, which allows the rapid creation of a line of new products with very complex helical shapes and makes it possible for them to be generated and manufactured by sending files anywhere in the world, taking them from virtual to concrete almost instantly.
    [0005] Many patents show the amounts paid for layer-based manufacturing machines: FR 2166526 (1973), USA 5,637,175 (1997), EP 1358994 (2003), WO2004 / 108398 (2004), etc.
    [0006] The principle of a rotating circular plate making it possible to distribute the work successively to stations placed around the plate is also very old (called transfer machines).
    [0007] This new possibility of design and construction of machines that build layer by layer is remarkable in that they have a circular container located at the bottom (B) that rotates continuously or step by step on a fixed base (D) and the interior of which is provided with vertically motorized cylindrical crowns independently (7) receiving the successive layers, and, in the upper part of the machine a fixed part that covers the container and comprises contained in an angular portion of the circumference surface of the lower container (Fig. 1), at least one manufacturing unit, which in turn is divided into several successive sections and along the cross section AA ', the first (1) distributes the product layer from a housing, the second (2) balances the thickness of the product layer or compresses it and sends the excess product that is distributed to the housing, the third (3) makes it possible to control and regulate the temperature of the next layer with a stationary plate, which is preferably microporous, the fourth (4) is the one in which the useful surfaces of the product layer to be maintained are scanned either by laser to melt them or by spraying an additive for agglomerating. them or other means to modify the consistency of the product, the fifth (5) makes it possible to control and regulate the temperature of the layer that has just been deposited, preferably using a hollow cylinder with a controlled and regulated temperature in which the periphery rotates with the layer, a sixth (6) makes it possible to treat and impregnate the layer before presentation to the next manufacturing unit by adding a complementary product by spraying or by the presence of a gas.
    [0008] It is also noteworthy that the independent circular crowns (7) sink individually and vertically and divide the surface of the container into circular sectors, which are treated independently by six stations of the upper part of the machine, which in turn is adapted for treat each of the crowns individually.
    [0009] When necessary, the successive positions of the stations (1 to 6) are moved in relation to each other.
    [0010] The lower container (B) rotates in a programmed manner on a stationary base (D) and that are temporarily joined together by manipulation, and the lower container is provided with lifting rings (9) and tilting rings (8) for this purpose.
    [0011] On the floor, motorized devices make it possible to fix the base on a specific and stable point during manufacture.
    [0012] It should be noted that, during the manufacturing periods, the machine is kept in an atmosphere and enclosure at a controlled temperature and the lower container is provided with a device that makes it possible to maintain a slight overpressure of the gas using a filtrate. compatible made from the controlled atmosphere of the enclosure.
    [0013] The schematic drawings and the elements indicated are provided without being limiting.
    [0014] The drawing (Fig. 1) shows, through an angular sector, an independent production unit that, in turn, is divided into several sectors (1 to 6). The remainder of the 180 ° half - circle of the drawing shows a top view of the circular crowns of the lower container (7).
    [0015] It is shown that the first zone distributes each layer of product over the entire circular portion (1) or in active circular crowns chosen from the lower container (7); the second balances the thickness of the product layer, or compresses it, and the excess product is recovered (2); the third makes it possible to control and regulate the temperature upstream (3); the fourth is when lasers write on the fusion product or by other methods that are used to add material, or to modify the consistency of the product (4); the fifth makes it possible to control and regulate the temperature downstream (5); and sixth is used to add an additional product by spraying or by impregnation or by the presence of a gas or vapor (6).
    [0016] The circular arrow shows the direction of rotation of the lower container, which is reversible (container R).
    [0017] Along the cross section AA ', the Figure (Fig.2) shows, as a non-limiting example, the product distribution device, and the drawing (Fig. 3) shows a device that balances the product layer , the drawing (Fig. 4) shows a device that makes it possible to regulate the temperature, and the drawing (Fig. 5) shows a spraying device for impregnating the product.
    [0018] Drawing (Fig. 6) shows manufacturing details in a diagram and in a non-exhaustive way of the lower container (B) of its lower chamber, a circular container (C) and the base (D), which are traditional elements used in construction of machines that do not claim any novelty in themselves, but are part of a whole: (8) tilting ring, (9) lifting ring (10) crown lifting screw (11), protective bellows for the screws, ( 12) screw motor (13), devices for motorized lifting and movement of the base, (14) rack gear motor for turning the central bearing container (15) to center the container on the base (16), electric energy transfer rings (17), bearings to rotate the container on the base, (18) dust protection skirts (19), the autonomy batteries of the movement of the base, (20) of the device to lock the base precisely in the position in the working position.
