The method comprises impressing a mechanical stress field in the notch root in a section of the slot, wherein the impressed mechanical stress field brings about a plastic deformation of the notch root. The impressed mechanical stress field is then progressively moved in the slot longitudinal direction of the slot. After this, the impressed mechanical stress field is removed again, wherein residual compression stresses remain in the notch root of the slot in the region of the slot in which the mechanical stress field was impressed.

  • Patent number: 7493788
    Abstract: A deep rolling roller head includes two housings for the deep rolling of the outer radii or fillets of split-pin crankshaft journals by means of two deep rolling rollers which are pressed into one of the two fillets under a rolling force while the crankshaft rotates around its axis of rotation. The two housings follow at the same time the different movements of the journals and support each other with their insides across from each other on a bearing plate. The insides of the housings bear on either side of the axis of rotation of the crankshaft and at a distance from it on an extension segment extending in the direction of the rolling force to below a contact point between the deep rolling rollers and the fillets to be deep-rolled. The bearing plate connected permanently to the inside and the extensions of one of the two housings.

    Abstract: The invention relates to a burnishing roller head (10) for burnishing radii (28) or recesses which respectively laterally define the bearing seats of main and lifting journals (3, 4) of crankshafts (1) for motors of motor vehicles. Two disk-shaped and cylindrical burnishing rollers (11, 12) with the same diameter and approximately the same width are arranged parallel and at a mutual distance from each other in the housing (9) of the burnishing roller head (10) and are mounted in such a way that they can rotate about a common horizontal rotational axis (18) in the housing (9) of the burnishing roller head (10). Said burnishing rollers (11, 12) respectively comprise, on the outer peripheral edges (22) thereof opposing each other, a rotating rounded projection (21) which enlarges the diameter of the respective burnishing roller (11, 12) by a pre-determined measure (24), the axial width of the burnishing roller (11, 12) extending simultaneously over a section of the projection close to the edge.

  • Patent number: 7387008
    Abstract: There is provided a new and improved apparatus and method for rolling workpieces such as crankshafts. The apparatus has first and second rolling heads mounted at spaced positions along a common rolling arm to receive a crankshaft bearing therebetween which can then be shifted relative to one another along the common rolling arm to close the heads or rolling tools for clamping onto the workpiece. The in-line clamping action and force provided by the tools on the rolling arm are created by actuation of a tall, thin cylinder assembly including a number of aligned individual cylinders sized to keep the width of the cylinder assembly to a minimum so that all of the rolling arms can likewise be of a thin construction pivotally mounted on one side of the crankshaft and axially spaced according to the crankshaft bearing spacing for rolling all of the bearings in a single rolling operation.

  • Patent number: 7316142
    Abstract: The present metal spin forming head includes two sets of rollers, with each set having a series of individual metal working rollers therein. The rollers of each set are circumferentially spaced evenly about the head, with each of the rollers of the second set being evenly positioned between corresponding rollers of the first set. The second roller set may be in a non-coplanar relationship with the first roller set. The first roller set comprises rollers having relatively broad widths, for forming the general contours of the workpiece. The second roller set comprises rollers having relatively narrow rims for forming circumferential grooves in the workpiece, resulting in corresponding beads within the workpiece for securing an article therein. The rollers are controlled independently of one another by a programmable logic control capable of driving the rollers cyclically as the workpiece (or spin forming head) rotates to form non-cylindrical shapes.

The reforming assembly generally includes a roller block having a pair of reform rollers and two pairs of outside reprofile rollers. A biasing means is operably interconnected to the reform rollers, such that the reform rollers extend to contact the inner surface of the bottom portion of the container when contacted by the bottom portion of the container. The outside reprofile rollers engage with an outer surface of the bottom portion of the container. The container reforming assembly is rotated, while maintaining the container body in a static non-rotating position, to create an internal can profile on the inner surface by the pair of reform rollers, and an external can profile on the outer surface by the outside reprofile rollers.
