Definitions

  • the present invention relates to a container manufactured of an alloy of superplasticity, and more particularly to a method of manufacturing a container by blowing a tube of a superplastic alloy.
  • the superplastic alloy spreads extraordinarily largely by a low working stress, it is subjected to such molding working as rolling. drawing, sheet working, press forging and extrusion. Further, the development of a manufacturing technique based on the blow molding is attempted recently. Unlike glass or plastics, however, the superplastic alloy is narrow in the temperature region in which it exhibits the superplastic flow, and does not always respond to a sudden working stress. It is therefore limited in moldability. ln consequence, even when the superplastic alloy is extraordinarily expanded compulsorily by merely raising the blow pressure, it cannot be uniformly molded. Particularly the molding of elaborate parts becomes imperfect, and a non-uniform thickness of the molded article or cracks in the surface arise. In this manner, the manufacture with the superplastic alloy has been technically unsolved.
  • the present invention intends to produce a novel container by utilizing the property of the superplastic alloy. Since the conventional techniques have worked the superplastic alloy under a condition exceeding the limit of thee moldability thereof, they have been incapable of manufacturing a product enduring practical use.
  • the invention has therefore accomplished the intention by the blow formation of the container in such way that a material is preheated so as to manifest the superplastic phenomenon, that it is somewhat inflated by a low initial pressure of at least 8 atm., and that it is thereafter given a molding pressure in the range of 7 atm.
  • the material is formed into a bottomed cylinder, the surfaces are smoothed and the dimensional precisions are arranged.
  • the external appearance of the product by the blow molding is made beautiful, and the outward dimensions of the finished article are made accurate.
  • the superplastic alloy Used the superplastic alloy are Zn Al (78 22), Al Cu (67 33), Al Si (88.3 11.7), Mg A1 (67.7 32.3), Mg Cu (69.3 30.7), Mg Ni (76.5 23.5), and so forth. These alloys are preheated at 200 300C at least 2 minutes, and while kept at a molding temperature below 600C, they are molded by the blow formation at a blow ratio of at the greatest 3 under the two stages of molding pressures.
  • a container of desired size and shape can be readily manufactured by placing the bottomed cylinder in a metal mold and subjecting it to the blow formation under the conditions as mentioned above.
  • the principal object of this invention is to provide a method which can manufacture a container of a superplastic alloy material.
  • Another object of this invention is to provide a method which can manufacture a container by the technique of blowforming a superplastic alloy material.
  • Still another object of this invention is to provide a container which is made of a superplastic alloy material.
  • FIG. 1 is a perspective view of a slab ofa superplastic alloy material.
  • FIG. 2 is a sectional view of a bottomed cylinder which is obtained by the impact molding. the compression molding or the vacuum molding of the slab;
  • FIG. 3 is a sectional view illustrating the state under which the cylinder is ironing-worked
  • FIG. 4 is a sectional view illustrating the state under which the inside surface of the cylinder at its opening is machined
  • FIG. 5 is a sectional view illustrating the state under which the inside surface of an inner part of the cylinder as is distant from the opening part is machined;
  • FIG. 6 is a sectional view illustrating the state under which the cylinder is inserted into a metal mold assembly in the open state
  • FIG. 7 is a sectional view illustrating the state under which the metal mold assembly in FIG. 6 is closed and under which the cylinder is blown out;
  • FIG. 8 is a front view of a finished product (container).
  • FIG. 9 is a perspective view of a tube ofa superplastic material.
  • FIG. 10 is a sectional view of the tube in FIG. 9 as is made a bottomed cylinder.
  • the present invention has the case of starting from the slab of a superplastic alloy and the case of starting from the tube thereof. In either case, it includes the various steps of preparation of the bottomed cylinder, mechanical preprocessing, preheating, blow formation, cooling, taking out the molded article, and finishing.
  • a slab l as shown in FIG. 1 is made in such way that a rolled material of superplastic alloy (Zn 78 Al 22 percent) having a suitable thickness as required for manufacturing a final product, for example, a container 10 shown in FIG. 8 is punched into a predetermined size and shape.
  • the slab is made by slicing an extruded bar of predetermined sectional shape at a fixed thickness.
  • a bottomed cylinder 2 as shown in FIG. 2 is made by subjecting the slab 1 to the impact molding, the compression molding or the vacuum molding. In the middle of the bottom 12 of the cylinder 2, a lug 15 is formed. Up to this step, the molding must be executed within the region of the superplastic property of the alloy. The temperature, the heating period of time, etc. need be sufficiently considered.
  • polishing signifies that with a file and/or buff, and it serves to increase the luster and smoothness of the outside surface of the cylinder.
  • the ironing working draws or squeezes the cylinder 2 with a die 3 as illustrated in FIG. 3.
  • the material of the cylinder surface 2 is stretched, to enhance the smoothness of the surface, to remove cavities created in the outside surface and to render the structure of the material finer. so as to obtain a container whose outside surface is beautiful.
  • the machining signifies to cut and work the inside surface 2,, of the cylinder in conformity with the shape of the final container as illustrated in FIG. 5.
  • the thickness distribution is made uniform.
  • a screw portion 11 to be formed on the outer periphery of the neck portion of the final container 10 as shown in FIG. 8 the inside surface 2,- of the corresponding part of the cylinder is cut and worked thin as illustrated in FIG. 4.
  • the neck portion is inflated well at the stage of work of blowing-out.
  • the fifth step is the blow step.
  • the preheated cylinder 2 is shifted to the blow step, which is generally performed in the order of the following substeps (I (5)- l.
  • the right and left split molds of the metal mold assembly are closed.
  • the bottom mold of the metal mold assembly is pushed up and set, to construct the blow mold assembl 5.
  • the preheated cylinder is inserted and arranged in the blow mold assembly.
  • the cylinder is heated. It is held at 260C i C by heaters inside the metal mold assembly.
  • a nozzle is inserted into the heated cylinder, and air or a gas is caused to blow thereinto.
  • the cylinder is blown out until it becomes the shape of the final container.
  • FIG. 6 illustrates the state under which the metal mold assembly is open.
  • the metal mold assembly consists of the right and left split molds 4, 4 and the bottom mold 6.
  • Each of the split molds 4, 4 contains the heater 7 therein.
  • a cavity 8 for molding the final product 10 is formed inside each split mold, while a neck portion 9 for molding the port portion of the final product is formed at the upper edge.
  • the cylinder is inflated by causing the fluid to blow thereinto from the blast port 14 of the nozzle portion 13. Since the cylinder has its central position held with the lug 15 of the bottom portion inserted into the depression 16 of the bottom mold 6, it is inflated at equal rates in the radial direction, and any partial thickness is prevented. As a modification, it is also allowed to provide the lug in the middle of the bottom mold 6 and to form the depression at the bottom of the cylinder.
  • the conditions of the blow molding at the sub-step (5) are as follows.
  • the blow time is 45 to 60 seconds.
  • the initial pressure is 10 atm. (2 to 3 seconds), and the molding pressure is 17 atm. (43 to 57 seconds).
  • an inert gas such as nitrogen and argon. heated to C C is used in order to prevent the molding compact from being oxidized and lowering in temperature.
  • the molding pressure is not once given at the molding, but an appropriate ratio for the elongation of the material is promoted by the initial pressure so that the cylinder can be molded into the precise shape of the final container.
  • a weak part dependent upon the thickness distribution is suddenly inflated to give rise to a thickness change and a shape change. This drawback is eliminated by the initial pressure.
  • the maximum blow ratio at this time was 2.7 in experiments.
  • the blown-out container of the final shape is taken out from the metal mold assembly manually or automatically.
  • the molded container is subjected to the various finishing sub-steps of l slicing and cutting the port portion. (2) washing the inside and outside of the container, (3) plating the outer surface of the container or coating it with paint. and (4) coating the inner surface of the container. (Modified Method) Description will now be made of the second case, namely. the method which starts from making a bottomed cylinder by providing a bottom for an extrusionmolded tube.
  • a bottom portion 22 is formed by blocking one end of the tube 20, so that a cylindrical body 21 as shown in FIG. 10 is prepared. In the middle of the bottom 22, a lug 23 is provided.
  • a method (A) in which the bottom portion is formed by heating and welding a separate component of the same alloy as that of the cylinder or a method (B) in which the bottom portion is formed by nipping one end of the cylinder by means of a metal mold or any other mechanism.
  • the third and succeeding steps are the same as in the first case. However, since the thickness change of the cylinder is achieved at the extrusion molding, the ironing working and the machining as seen at the third step of the first case are omitted.
  • the present invention can readily mold a metallic container in such way that, after finishing the inside and outside surfaces of a cylinder of a superplastic alloy material, the stepped blow molding from the initial pressure to the molding pressure is carried out.
  • the molding of the container of the superplastic alloy material is attended with difficulties.
  • a beautiful final container can be smoothly molded without losing the smoothness of the surfaces and without causing partiality in thickness and cracks, in such way that the blow pressure is bestowed stepwise while maintaining the temperature of the process in which the internal structure of the material changes.
