    1444256 Sealing containers by welding; extruding SKF INDUSTRIAL TRADING & DEVELOPMENT CO BV 22 June 1973 [26 June 1972] 29747/73 Headings B3R and B3P [Also in Division B5] In a method of sealing material in a container at a pressure less than 10<SP>-1</SP> torr, the container 4a, Fig. 1, or a portion thereof is filled with the material 6 supplied through the open top of the container, the top layer of the material which may be the same or a different substance from that of the remainder of the material being fusible. The container is located, with the material therein, in a chamber 1, the pressure within the chamber is reduced to less than 10<SP>-1</SP> torr and, the top layer of the is fused to the wall of the container after which it solidifies to form a seal welded to the wall and cooperating therewith to enclose totally the remainder of the material. The material may be in powder, granular or tablet form, in which latter case the top tablet, is partly or wholly fused to the wall. In other examples the top layer may have the same composition as the wall, which may be of metal or plastics, e.g. P.V.C. In Fig. 1, electron beam welding is used to fuse the material, the welding device including the vacuum chamber 1. The containers are transported on interconnected conveyer belts 3a-3c and a vibrating device 5 compacts the powder material. Means for maintaining the material in the container 4b during welding may be as shown, electromagnetic coils 10, if the material is magnetizable. In Fig. 5, rotating friction welding discs 36a, 36b are alternatively used to weld both ends of the container 39 simultaneously. The sealed containers produced are said to be particularly suitable for extrusion into bars or tubes of round or other section.

    专利说明:

    The invention relates to the processing of metals by pressure, and in particular to containers for isostatic pressing of products from powders and granules.
    A container for isostatic pressing of products from powders and granules is known, containing a sealed thin-walled shell with machined material located inside it. The container is equipped with tubular shafts connected by connecting means to a vacuum unit. After creating a vacuum in the container, it is sealed by 15 sealing and subsequent partial cutting of the tubular trunks £ l].
    However, the container thus obtained has protrusions (parts of the cut tubular trunks), which 20 may be damaged during transportation, which: will lead to depressurization of the container.
    The purpose of the invention is to improve the quality of the container.
    The goal is achieved by the fact that. in the container for isostatic pressing of articles made of powder and granular materials, containing a sealed thin-walled shell with the processed material located inside it, a lid is fixed by fusion in the upper part of the shell on its inner walls.
    The lid is made in the form of a tablet, compressed from the processed material and fused around the periphery,
    The lid is made of container material.
    Due to this, a special connection of the vacuum pump to the container is not required, there is no need for a special device for cutting tubular trunks, which leads to high physical and operational qualities of the container.
    The hgi drawing schematically depicts a proposed container.
    - The container consists of a thin-walled hermetic shell 1, inside of which a granular or powdery material to be processed is placed 2. In the upper part of the shell 1, a 'flat lid 3 is fixed on its inner edges by melting its edges around the periphery. Flat, the lid 3 can be made in the form of tablets, compressed from the processed material or from the material of the container.
    The manufacture (sealing ^) of the container is carried out as follows. at once.
    The processed material 2 is placed in a thin-walled hermetic casing 1, compacted, for example, by vibration, and then the container is evacuated by means of a (vacuum chamber, after which it is sealed. For this, the lid 3 is fixed on the upper part of the casing and carry out the flashing of the edges of the lid along its periphery using an electron beam installation. using an electron beam installation.
    The melted top layer of the processed material acts as a flat sealing cover. This ensures reliable ger.
    containerization of the container with almost complete exclusion of depressurization. during its transportation.
