DEVELOPMENT OF A MATHEMATICAL MODEL FOR DETERMINING THE SURFACE AREA SETTINGS ROLLERS AND WORK PIECE WITH ROTARY SURFACE PLASTIC DEFORMATION ROLLER WITH STRAIGHT AND CONVEX IMAGES
The article describes the features of rotary processing surface plastic deformation outer diameter thin-walled tubes of long rollers with a concave forming. It shows the calculated surface processing circuit plastic deformation of the roller with a concave forming. The correlation values of self-serve machining tool on the angle of installation of the deforming roller relative to the work piece axis, defined by the law of change the half-width of contact between the roller surfaces and long thin-walled tube. Is a plot of allowing the installation to determine the angle of the deforming rollers relative to the work piece axis, depending on the required value of self-serve. Also presents a scheme for determining the equivalent circle and half-length of contact that can be used to determine the law of variation of the halfwidth of the contact between the surfaces of the deforming roller driven around the rotary tool and the outer diameter thin-walled tubes.
