    Circular-cylindrical bodies (2) are formed from rectangular sheet-metal blanks by rounding and longitudinal seam welding. In a first spreading operation, these bodies are expanded into an oval cone over their entire length and then relieved of stress again. In a second spreading operation, the bodies (2) are then expanded in such a way that they receive their polygonal, in particular rectangle-like cross-sectional shape over their entire length. The bodies are thereby put under stress at their end edge zones in such a way that these edge zones do not become wavy and can therefore be connected easily to a can lid or base. …<IMAGE>…

    The invention relates to a technique for the manufacture of cans used in an articulated canning pum.
    The purpose of the invention is to increase reliability during the subsequent fitting of the bottom and the cover and increasing the convenience of the can in circulation.
    FIG. 1 shows the device, a general view; in fig. 2 - the main cross conveyor; in fig. 3 - expansion mandrel of the main transverse conveyor; in fig. 4 - additional cross conveyor; in fig. 5 - the workpiece at the time of transfer from the mandrel of the main conveyor to the mandrel of the additional conveyor; in fig. 6 - 10 - billet in the implementation of the deformation.
    Billets 1, processed in the device, have a cylindrical shape with a circular cross section, a longitudinal weld 2 and an annular ring 3, located near one of the ends (Fig. 6).
    The device comprises a frame 4 with a console 5 supporting the engine 6 and a gearbox 7 for driving a longitudinal conveyor 8. The conveyor 8 is made in the form of a main transport belt 9 and two lateral transport belts 10 also moving from the gear 7, the side belts 10 approach in the direction of movement of the workpiece one.
    On the bed4 fixed racks 11 and 12.
    On the rack 11 is installed the main cross conveyor, in the form of a turntable 13, mounted with the ability
    step rotation from a drive (not shown) around an axis 14 parallel to the axis of movement of the conveyor 8. On the turntable 13, eight expanding mandrels 15 are uniformly placed, the axes of which are parallel to the axis of rotation of the table
    Each mandrel 15 is made in the form of a housing 16 fixed on the table, carrying sector 17, mounted with the possibility of radial movement from the wedge 18 and held by the spring 19. The wedge 18 moves along the axis of the mandrel from the pusher 20 connected to the power cylinder 21, On rack 11, Guides 22 for workpiece 1 are also mounted on housing 16.
    An additional cross conveyor is mounted on the rack 12 in the form of a rotary table 23 mounted with the possibility of stepwise rotation from a drive (not shown) around an axis 24 parallel to the axis 14 of rotation of the table 13. Eight expansion rods 25 are circumstantially fixed around the table 23 .
    The table 23 is positioned so that one of the mandrels 25 is coaxial with one mandrel 15 on the table 13.
    Each mandrel 25 is made in the form of a body 26 fixed on a table and carrying four sectors 27 connected by springs 28 and radially moving from 29. moving from pushers 30 connected with a power cylinder 31.
    The wedge 29 and the wedge 18 of the mandrel 15 are working in the same direction.
    Attached to body 26 are longitudinal ribs 32 in contact with sectors 27. The sectors have an approximately square cross-section and are made up of sections 33 and 34 in length. The main sections 33, located closer to the rotary table 23, form a truncated pyramid of the sector. The 33 sector sectors are consumed much further than the 34 sectors.
    On the table 23, on the side opposite to the placement of the mandrels, brackets 35 are installed (two on the mandrel), carrying rotary locks 36, which are mounted with an annular spring 37. The wedge 29 is fitted with rear flanges 38, which engage mandrel 25 in the position of the distribution of the workpiece.
    Between the rotary tables 13 and 23, a transmitting conveyor is installed in the form of two bodies 39 mounted on opposite sides of the mandrels 15 and 25 in their mutually coaxial position. Enclosures are mounted with the possibility of reciprocating movement
    guiding longitudinal rods 10 and provided with transverse rods 41, on which grippers 42 with vacuum suction cups 43 are mounted, connected to a vacuum pump (not shown).
    A tool 44 is mounted on a stand 44 mounted on the bed 4 for making longitudinal recesses on the blanks 1.
    The device is equipped with an additional transmitting conveyor (not shown), made similar to the main transmitting conveyor and located at the removal position of the workpiece 1 from the mandrel 25 for transferring it to the additional longitudinal conveyor 46.
    A device for the manufacture of can bodies works as follows.
    The blank 1 from the welding machine 47 is fed to a longitudinal conveyor 8, where, moving on the belt 9, it is simultaneously crimped on both sides by converging belts 10 and acquires an oval-cylindrical shape (Fig. 7). The longitudinal weld seam 2 is located between the strips 10 in the area of the greatest curvature of the workpiece. To prevent rotation of the workpiece, the tape 9 is magnetized or moved along a magnetic guide.
    From the knitter 8, the blank 1 falls on the expanding mandrel 15, which is at that moment at the receiving position, and when the wedge 18 is exposed to the sectors 17, the blank 1 acquires an oval-conical shape (Fig. 8).
    When the table 13 is rotated into a position in which the mandrel 15c is placed coaxially with one of the mandrels 25 on the table 23, the transfer conveyor comes into play, using the grippers 42 transferring the blank from the mandrel 15 to the expanding mandrel 25 coaxially with it.
    On the mandrel 25, the blank 1 takes the form of a truncated pyramid 48 with an edge portion in the form of a prism 49 adjacent to the smaller base of the pyramid (Fig. 9). Due to the presence of the latches 36, the mandrel 25 is locked in the expanded state, holding the workpiece 1,
    When the table 23 is rotated to the working position of the tool 45, it makes longitudinal grooves 50 on the wide sides of the workpiece 1 (Fig. 10).
    Upon further rotation of the table 23 on the aieflv: OLuyto position, the latches 36 release the flange 38 of the wedge 29, the sector 27 is reduced and the workpiece 1 is removed by an additional transmission conveyor and transmitted to the additional longitudinal convector 46.
