    A tool, and method, for making the outer member of a constant velocity universal joint of the cross-groove type, the outer member being of hollow form having in its interior two sets of helical grooves of opposite hand. The tool comprises first and second parts (15, 21) mounted for axial movement relative to one another, the parts having portions (23, 17) which can be brought into and out of mutual intercalation by such axial movement, the portions (17) carrying projections (18) which form the grooves of one hand and the portions (23) carrying projections (24) which form the grooves of the other hand. When the tool is used to produce a joint outer member by being placed in a hollow blank which is forced through a die to form the material of the blank around the projections, the tool is withdrawn from the formed blank by helically withdrawing the portion (23), with its projections (24) moving along the grooves formed thereby, followed by helically withdrawing the portion (17) with its projections (18) moving along the grooves which they have formed.

    专利说明:

    The invention relates to the processing of metals by pressure, in particular, to the design of devices for the production of hollow parts with internal relief.
    The purpose of the invention is the expansion of technological capabilities.
    The device shown is a general view; figure 2 - upper deforming tool; FIG. 3 shows an embodiment of the upper deforming tool; figure 4 - billet, processed in the device section; in FIG. 5, view A in FIG. 4; 6 shows the resulting part, the cut; figure 7 - view B in Fig.6.
    A device for producing hollow parts with an internal relief comprises a lower working tool I and an upper driving deforming tool consisting of an element 2 with a working relief on the side surface in the form of alternating protrusions 3 and depressions 4 at an angle to its axis. In element 2 there is a shank in the form of a rod having an end thickening, which is an additional forming element 6, having a relief in the form of alternating protrusions 7 and depressions 8, whose longitudinal axes are located

    at angles different from the orientation angles of the axes of the protrusions and depressions of the upper deforming tool. At the same time, between the latter and the additional formative tool are elastic means 9,., For example, in the form of springs.
    The device is equipped with a stripper in the form of radially arranged elements 10. In the lower part of the device, a window 11 is made to remove the finished product. Position 12 marked the workpiece.
    The device works as follows.
    The blank 12 is installed in the lower working tool and is deformed by the upper working tool. Removing the top
    The working tool from the cavity of the finished product is produced as follows. First, an element 2 is removed from the product cavity, which moves along a helical line with the release of the projections 3 from the grooves 13-15 of the product. After removing the element 2, the elastic means 9 are compressed, the additional shaping element 6 remains in the product. Then the forming element 6 is removed by moving along a helix in the direction opposite to the movement of element 2.
