    The blank 1 for the collector ring 2 of the collector is made of a material suitable for the collector, for example copper. The blank t has the shape of a liner, at the end of the shank 3 of which the flange 4 is molded. On the inner wall 5 of the shank 3, they are equally spaced each other and parallel to the longitudinal axis of the liner are segmented partial grooves 6, which separate each other. from the other, collector segments 7 to the lintel, 8 on the narrow surface of the liner. Segmented partial grooves 6 are continued in the flange 4 in quality. . . splines 9. The tongs 9 divide the flange 4 into the connecting scallops 10, corresponding to the individual collector segments 7. The connecting combs 10 are connected to each other along the outer edge of the flange 4 by a jumper 11. The blank 1 is made, for example, by stamping by pressing. It has a larger diameter than the collector ring 2, and is equipped with segment partial grooves 6 and serving as partial scallops with slots 9 of greater width than the finished collector ring 2 has.

    In order to convert billet 1 by means of cold working with pressure into a collector ring 2, the shank 3 and flange 4 of billet 1 are reduced in diameter. The billet 1 is put on a stamp that has teeth that are included in the segment partial grooves 6. Pushers acting radially on each collector segment 7 together with a connecting comb 10, press on the collector segments 7 between the teeth of the forming stamp. The jumpers 8 and 11 are bent outwards and the segment partial grooves 6 and the splines 9 are narrowed to a predetermined size of the collector ring 2. The reduction is carried out in a single or multi-step stroke using a differentiated single or multi-step stamp. The subsequent execution of the dovetail-shaped fasteners at the inner end of the collector segments 7 is carried out with a calibration device when the working stroke is continued or when the forming stamp is retracted from the workpiece 1. The forming stamp is also used to eject the collector ring 2.
    Cold working of the workpiece 1 into the collector ring by reduction is carried out in a multi-stage pressure treatment tool in one working stroke.

    The pressure tool is shown in FIG. 10 in the end of travel position. In its original POSITIONING, intended for the insertion of the workpiece 1, the middle and upper deforming plates 55 and 24, having a clamping device 56 thickness of the chains and a pusher 59, the pressure plate 15 and the upper stamp 37, are separated from the lower holding plate 12 and the clamping device machined parts - on the direction of stamp stamp 45 and the forming ring. 51 and hold in their uppermost position. In this case, the upper stamp 37 is so drawn back into the central hole 67, that the upper part 39 of the mold and the calibration mark A2 are moved out of the hole 58 in the area of the pushers 59. The lower stamp 21 is advanced in the direction The A5 is so stamped that the front side of the lower part 22 of the formative stamp adjacent to its end face lies in the same plane as the sections 53 and 54 of the front side 46 and, therefore, with the base part of the workpiece.
    The blank 1 is put on the lower part 22 of the forming stamp in such a way that its flange 4 is located in sections 53 and 54 of the front side of the base device of the part being machined. In this case, the projections 50 in the sections 53 and 54 of the safety parts 49 enter the pomerania 9 in the cut 4 of the workpiece 1. Thanks to this, the workpiece 1 is fixed in its position in the tool for pressure treatment. In addition, the ends 50 of the safety parts 49 help to make the spitz 9 when forming the workpiece 1 into the collector 2 of the required shape.
    On the first work strap / rim for reducing the workpiece 1, the middle and upper retaining plates 55 and 24 are moved axially to the billet 1 until average. the holding plate 55 does not lie on the lower holding plate 12. Then, the pusher-based clamping device 56 spans CBottM with the opening section 58 of the blank 1, while the base of the slots 57 and the edge of the pushers 59 are on
    the surfaces of the end sides 53 and 54 and the end side of the flange 4 of the workpiece 1. To counter the force of the spring device 68, the upper holding plate 24 with the bell-shaped pressure plate 15 is moved axially to the middle holding plate 55. At the same time, the conical section 66 of the pressing l5 presses on the bevelled outer face side of the 32 pushers 59 and simultaneously moves the pushers 59 in the radial direction to the collector-. 7 segments of the workpiece 1, and the segments 7 are pressed between the teeth 23 of the lower part 22 of the forming stamp, the connecting segments 7 of the strip 8 are bent outwards, and the segment partial grooves 6 are tapered according to the shape of the teeth 23, at the same time the shoulder 61 of the pushers 59 presses on the edge of the flange 4 of the workpiece 1 and on the subsequent attachment of the scallops 10. In this case, the webs 11 between the splines 9 are also bent outwards and the bulbs 9 are narrowed.
    If the collector segments 7 are adjacent to the side surfaces of the teeth
    At the same portion of the forming stamp 22, the movement of the upper holding plate 24 is stopped by means of the natcim plate 15. The lower stamp 21, having the lower part 22 of the forming stamp, is pulled back into the guide stamp 45, while the upper stamp 37 moves on the workpiece 1 until as long as the upper part 39 of the forming stamp is not seated in the workpiece 1. Then the pressure plate 15 due to the upper holding plate
    24 axially moves further to the middle retaining plate 55. The conical section 66 of the pressure plate 15 again presses on the beveled front side 32 of the pushers 59. The pushers 59 together with the bale 61 press the collector segments 7 and phagan
    4 so that the segments 7 are pressed between the teeth 40 of the upper part of the forming head of the body and the recursors 1 and 8 and 11 are bent, giving it to the outside. If the pressure plate 15 with its face side rests on the middle holding plate 55 (FIG. 10), then the working stroke is finished, and the workpiece 1 is reduced to the desired dimensions of the diameter of the shank, segment partial grooves 6 and pinnacles 9 (FIG. 8).
    Then, while the pressure treatment tool is kept closed, first of all the upper stamp 37 is retracted backward. In this case, the upper part. 39, the shape of the lean stamp is moved from the workpiece 1, and then the calibration ring 42 passes through the workpiece 1. The calibration one. the ring 42 again forms the inner ends 43 of the collector segments 7 into the fastening means 44, which, in the form of a dovetail, continue in the direction of the perimeter into segmented partial grooves 6. The billet is then converted into a collector ring 2 by cold working.
    If the upper stamp 37 moves back further to its original position, the pressure tool opens. Here, the upper holding plate 24 is pressed from the middle holding plate 55 by the force of the loading device 68, the spring device 31 pressing the pushers 59 outwards. Then, both holding plates 24 and 55, having a pressure plate 15 and a pusher-based base 56, pushers 59 and a spring device 31, are jointly moved to their original position from the lower holding plate 12. At the same time, the lower stamp 21 with the lower part 22 of the forming stamp moves back to guide cylinder 45 to its original position. In this case, the lower part 22 of the forming stamp presses against the front side of the connecting scallops 10 of the collector ring 2 and separates it from the ends 50 of the safety part 49 so that the collector ring 2 can be removed from the tool for pressure treatment.
    In the second example of execution of the tool, 45 Cross-section of the tooth of the control teeth for processing by pressure 82 of the first section of the mold
    (FIG. 10) the fastening means 44 are formed during the return stroke of the upper stamp 37 and the lower stamp 21 acts upon rotation to its original position upon completion of the pressure treatment process at the same time as an ejector for the collector ring.

    If the splines 9 and the segmented partial grooves 6 are to be reduced only to a small size, it is sufficient to execute the form-forming stamp inseparable and one-step. However, if, for example, large forces of plastic deformation appear in the blanks for large collector rings, the reduction can be carried out in more than two stages. In this case, the lower part 22 of the formative stamp according to FIG. 2, 3,4,5,6 and 10 can be made two-stage or multi-stage, and the upper part 39 of the forming stamp is used for the last reducing stage, it is connected to the calibration ring 42
