METHOD OF PRECISION ADJUSTMENT OF THE DEVICE FOR RADIAL SHAPE FORMING FOR SHAFTS Russian patent published in 2018 - IPC B21J13/02 B21K1/12 B21K31/00 

FIELD: technological processes.

SUBSTANCE: invention relates to the treatment of metals by pressure and can be used for the radial shaping of splines on the workpieces of the shafts. For shaping a device in the form of a casing is used with a separator having a mounting hole and radial grooves. In the grooves, punches are placed with the possibility of removing punches from the shaft blank by means of polyurethane buffers. Device is provided with a mandrel with a wedge mechanism for the radial stroke of punches. For precision adjustment of the device, a cylindrical test sample is installed in the separator inlet hole, the outer diameter of which is equal to the initial diameter of the shaft blank. Adjust the radial position of the punches by moving them to touch the working surface of the test sample with the same force. Extrude the test sample with punches to produce a slotted-toothed crown and control the accuracy of the shape of the slotted-toothed crown and the radial position of the punches relative to the test specimen. In case of detection of a violation of kinematics, the punches move the radial position of each of them.

EFFECT: as a result, the kinematic accuracy of the position and the radial stroke of the punches during the operation of the device are increased.
