RU2011151412A - METHOD FOR PROCESSING A PROFILE SHAFT WITH A SEGMENT PROFILE SHOT - Google Patents

Abstract

1. A method of processing a profile shaft with a segmented profile cutter, comprising chiselling parts under rolling conditions with a shaped cutter, in which the cutter performs a reciprocating movement of the cutting, and the part is a relative feed movement, characterized in that a special segmented cutter is used to process the profile shaft, designed through the application of the graphical method of forming, the edge line of the cutting part of which is designed to process one face of the processed profile shaft at the same time, when they are run-in for each revolution of the segmented profile cutter near its own center of rotation, one face of the profile shaft is restored, that is, the restoration is performed segmentally, while they are set at a predetermined center distance equal to half the sum of the diameters described near the profile shaft and inscribed in a segmented profile cutter of circles so that the elements of the profile shaft correspond to the elements of the segmented cutter for lack trimming and overlapping profiles, while the ratio of the angular rotational speeds of the segmented profile cutter ω and the profile shaft ω is expressed by the formula: where n is the number of sides of the profile shaft 1; ω is the angular velocity of the segmented profile cutter 2; ω is the angular velocity of the profile shaft 1.2. The method according to claim 1, characterized in that in order to restore several faces of the profile shaft during the mutual running-in of the segment profile cutter and the profile shaft, it is necessary to make a multiple of the number of faces of the profile shaft of the segment speed

Claims (2)

1. A method of processing a profile shaft with a segmented profile cutter, comprising chiselling parts under rolling conditions with a shaped cutter, in which the cutter performs a reciprocating movement of the cutting, and the part is a relative feed movement, characterized in that a special segmented cutter is used to process the profile shaft, designed through the application of the graphical method of shaping, the edge line of the cutting part of which is designed to process one face of the processed profile shaft at the same time, when they are run-in for each revolution of the segmented profile cutter near its own center of rotation, one face of the profile shaft is restored, that is, the restoration is performed segmentally, while they are set at a predetermined center distance equal to half the sum of the diameters described near the profile shaft and inscribed in a segmented profile cutter of circles so that the elements of the profile shaft correspond to the elements of the segmented cutter for lack of cropping and overlay profiles, wherein the ratio of the rotational angular velocities ω segmental profiled cutter and _cutter shaft profile ω _prof.vala expressed by the formula: $$\frac{{\omega }_{d\mathrm{about}lb\mathrm{I\; am}\mathrm{to}\mathrm{but}}}{{\omega }_{PR\mathrm{about}f.\mathrm{at}\mathrm{but}l\mathrm{but}}}=\frac{\mathrm{one}}{n},$$

where n is the number of sides of the profile shaft 1; ω _dolbyak - the angular velocity of the segmented profile dolbyak 2; ω _{prof. shaft} - the angular velocity of the profile shaft 1. 2. The method according to claim 1, characterized in that for restoring several faces of the profile shaft, during the mutual running-in of the segment profile cutter and the profile shaft, it is necessary to make a multiple of the number of faces of the profile shaft of the revolutions of the segment profile cutter.
