    1537156 Forging crankshafts INSTYTUT OBROBKI PLASTYCZNEJ 4 March 1976 [15 March 1975] 08602/76 Heading B3H A method of making a crank throw which includes a pair of opposed arms and a pin interconnecting the ends of the arms, comprises forming a blank having a pair of end blocks and a neck interconnecting the end blocks, the neck having end portions diverging towards the end blocks, and displacing the neck laterally of its axis while simultaneously pressing together the end blocks whereby material from the neck forms the pin and material from the blocks forms the arms. The blank is made from a starting piece 14 in the form of a cylinder with an annular groove in its middle and it is placed in a shaping device having shaped segments 11 which locate in the groove. A easing 12 is lowered over the segments to force them radially inwardly and the casing is secured by pivoted hooks 13 engaging a rim portion of a ring 10. When the hooks are engaged, sleeves 15, 16 are removed and the blank is formed in a pressing operation, Fig. 18 (not shown). The blank is then placed in forging dies 6, mounted in holders 22, and it is secured in the dies by wedge shaped inserts 23. Blocks 28 are placed on the inserts 23 and a press ram 27 is actuated through a part of its stroke. The blocks 28 are removed before completion of the ram's stroke and as the ram descends, a punch 8 bears on the neck of the blank to offset the pin laterally, while wedge shafts 26 drive the die holders 22 towards each other to shape the crank arms.

    no billet; in fig. 4 - Chechen B-Bfig. on 3; on fig. 5 shows a finished product, in FIG. 6 shows a section B-B in FIG. five; FIG. 7 shows an apparatus for carrying out the method at the initial moment of operation in FIG. 8 is a partial sectional view of the device. Fig.9 device at the final moment of operation.
    The method is carried out as follows.
    The original billet 1 is subjected to deformation, the shape on it of the draft cheek 2 and the connecting rod neck 3.
    The upsetting forces Pj are applied to the end surfaces of the workpiece, and the force P ensures the formation of the crank neck in the direction perpendicular to the direction of application of the upsetting forces. During the formation of the cheeks, flat sections 4 are formed on their forming surface, forming a wedge profile with an angle at the apex and a greater angle of self-braking, which contributes to the directional flow of the workpiece material with favorable fiber arrangement when forming the crank neck, due to the creation of backwater forces along these flat areas. With further application of effort, R. and the material of the workpiece fills the cavities of the matrices, as a result of which the final shaping of the product occurs (Fig. 5 and b).
    A device for carrying out the method comprises a base, in supports 5 of which the sliders with matrixes 7 are mounted.
    The sliders 6 have wedge surfaces interacting with wedge: stops 8. A punch 10 is mounted on the upper movable plate 9. The dies are made with wedge working support sections 11 forming a wedge profile with an apex angle greater than the self-braking angle. The sliders b are hingedly connected to the supports of the 5 bases by the levers 12. Therefore, their interaction with the wedge bearings 1 and 8 creates the possibility of their oncoming movement.
    The device works as follows.
    When raising the top plate 9, the sliders b with the dies 7 are divorced. The blank is placed in the device, placing it on the surfaces of 11 matrices. When lowering the top plate of the punch. 10 affects the middle part of the workpiece, and the matrix - on its end surface. The workpiece material under the action of deforming forces fills the working cavities of the dies, as a result of which the product is formed.
    The proposed method and device make it possible to obtain high-quality single-crank elbows, due to the creation of a favorable fibrous structure in the product, with high productivity and reduced loading of the device elements.

    Claims (2)
    [1]
    Invention Formula
    0 1- A method of manufacturing cranks by shaping a draft of cheeks and a crank neck on a workpiece by applying to the bridge between the cheeks a deforming force in a direction perpendicular to the direction of slump force, characterized in that, in order to improve the quality of products when they are made in the form of single crank knees, when shaping the cheeks, flat areas forming a wedge profile with an angle at the apex greater than the self-braking angle are formed on their forming surface, and the crank neck shaping is impl communicate with the application
    5 backwater forces on the indicated flat areas.
    [2]
    2. A device for carrying out the method according to claim 1, comprising a base with matrices mounted therein,
    0 fixed in sliders with wedge surfaces, as well as a movable top plate with a punch, equipped with wedge lugs, which differs from the fact that the dies are made with wedge working support sections that form a wedge profile with an angle at the apex and a greater lag angle, and the sliders are hinged to the base by means of levers.
