    专利说明:

    The invention relates to the field of welding and can be used when welding the claw to the body of the ontainer.
    The purpose of the invention is to ensure the tightness of the welded joint by creating optimal conditions for compression of the body and the flange.
    The figo shows the punch before welding, cross section; on fig2 - the same, in the process of welding; In the same 5th embodiment of j in FIG. 4, the diagram of the ratio of the magnitudes of the displacement of the elements of the expandable element J in FIG. 5 is the fastening scheme of the expandable element; on phnob - punch
    The punch contains a holder 1 of the container body 2, a ring 3 for forming the flat workpiece of the lid 4, a punch 5 for forming the workpiece of the collar, pressing the lid 4 into the body 2 of the container and welding them
    The holder is provided with an inductor 6, which creates a high-frequency magnetic field when welding the body 2 with the lid 4 The punch consists of two nodes that move relative to each other in the axial direction. The forming punch unit is made in the form of a hollow body 7 and the lid 1 8, which
    fastened to pin 9 by screw Yuo Between
    The upper surface 11 of the Kirsch 8 and the lower end of 12 of the housing 7 is formed by a gap to accommodate the expandable node 13 of the punch in it
    The punch is mounted on the rod 14 and the rod moves along with it in the axial direction from the position above the ring to the welding position inside the container body.

    it by means of springs 15. The uncoupling unit 13 is rigidly fixed on the axle 16 mounted on the rod 14,
    The expanding unit 13 is made in the form of a disk having a cup-shaped axial section. The outer dimensions of the disk are equal to the outer dimensions of the body of the forming unit in the non-operating state of the punch and somewhat larger than these sizes in the working state. The thickness of the disk, but at least in its working part. the cross section of the disk is similar to the shape of the cross section of the body and the cover of the forming unit
    In order to prevent the formation of wrinkles on the product, a supporting disk 17 can be installed over the expandable assembly, the contours of which correspond to the cross section of the forming unit crush and the external dimensions are smaller than the external dimensions of the expandable assembly.
    In the embodiment according to FIG. 3, the punch is provided with two supporting discs - a lower 17 with a protrusion 18 and an upper 19, a protrusion 18 abuts the end of the expandable disc disc. The disc 19 is fixed on the tubular shaft 20 moving relative to the stem 14o.
    The punch may be either round, oval, rectangular, or polygonal, preferably with rounded corners or some other; the shape corresponding to the shape of the elements to be welded
    According to FIG. 6, the device is made without a body 1:; its assembly. The cover blank is placed on the forming ring 3 and when the punch 5 is moved downwards, the board is bent up, along which the lid and container body are welded.
    During the welding process, the actuator stem acts on the disk of the expandable part, which partially or completely condenses, thereby increasing the outer surface of the disk, pressing the welded elements. Depending on the required degree of increase in the disk contour, its material can be more or less elastic or deformable. It can be made of rubber, rubberized fabric, elastic plastic or similar material. If necessary, a relatively small increase in contour is possible. lzovanie relatively hard or harder reinforced rubber or metal, such as brass, spring steel and t.Po
    According to the figoZ version, the expansion of the disk of the node 13 is carried out by displacing the tubular shaft 20 °. When the projection 18 of the upper disk 19 is made with a diameter smaller than the diameter of the expandable node 13 in an idle state, the disc-shaped friction surface 11 of the shaft 11 and the end 12 decrease. housing 7 about
    The amount of decompression of the disk of the node 13 is determined by the ability of the disk to move in the vertical direction.
    FigoZ shows an example of a non-circular container. In this case, the disk of node 13 has a different in two directions horizontal magnification (dL and dK) when moving vertically to the distance IL If the unclamping disk in this case is fixed in the center or near to it, the disk should receive a greater increase in the direction of dK than in the direction of dLo. In some cases this can be used to obtain a greater contact pressure in certain places. To eliminate this phenomenon, the disk should be made of the same shape. As the body of the container and secured at the edges. The result is the same expansion in all directions.
    The outer edge of the expandable disc can be straight, rounded dotted, or any other shape. Change the surface of the lower disc 17,

    an interaction with its expanding disc, and giving the lower end 12 of the housing 7 a corresponding shape, you can direct the edges of the expanding disc so that they fit to the side of the rim 4 very close to its plane or another specified location. For example, when making a round container with a diameter of 100 A -110 mm expandable disc may be made of urethane rubber having a hardness of 60-100 ° Shore, preferably 90-100 ° Shore, and the outer portion may be 2-5 mm thick or preferably 3 mm thick.
    In the proposed device, the unclamping element is forced. Moves both in the direction of decompression and in reverse direction. It can be managed more quickly and reliably. The exact direction of pressing the unclamping element is possible. A certain width of the compression zone can be used. thickness of the expandable disc, as well as the shape of other elements, it is possible to vary the pressure force, localize the pressure surface and change the locations application davlesh
