摘要： In an inertia-press-fit method in which a kinetic energy is applied to at least one of two members in a direction which causes the two members to approach each other, and the two members are press-fitted with each other, an end surface 80 of the first member 10 and a bottom surface 82 of the second member 12 are caused, for stabilizing a relative position of the two members at a time when the press-fitting ends, to butt each other to define the relative position of the two members 10, 12 at the time when the press-fitting ends and, immediately after the butting, at least one of the two members 10, 12 is caused to plastically deform and thereby absorb a remaining kinetic energy of the one of the two members. Thus, the relative position of the two members 10, 12 when the press-fitting ends is stabilized. In the case where respective plastic-deformation capabilities of the two members 10, 12 are great, a maximal value occurs to a graph whose axis of abscissa represents kinetic energy and whose axis of ordinate represents amount of deviation of relative position of the two members. If the respective plastic-deformation capabilities of the two members 10, 12 are so chosen as to decrease the maximal value, then the amount of deviation of the relative position is decreased even though the accuracy of control of the applied amount of kinetic energy may be low.

摘要： An inertial press fitting method for press fitting two members to each other by imparting a kinetic energy to at least one of the two members in a mutually approaching direction, wherein the relative positions of the two members (10, 12) at the end of press fitting are specified by bringing the tip end face (80) of the first member (10) into contact with the bottom face (82) of the second member (12) for the purpose of stabilizing the relative positions of the two members at the end of press fitting and a kinetic energy remaining in at least one of the members (10, 12) immediately after the contact is absorbed by the plastic deformation of at least one of the members (10, 12) to thereby stabilize the relative positions of the members at the end of press fitting. In addition, increased plastic ductilities of the members (10, 12) will show a maximum value on a graph drawn on coordinates with kinetic energy on the horizontal axis and relative position deviation between the members on the vertical axis. By selecting the plastic ductilities of the members so as to minimize a maximum value, a relative position deviation can be reduced even if a control accuracy of the imported kinetic energy is low.

摘要： PURPOSE:To obtain inexpensively a titled forming device that can form plural grooves on inner peripheral face of a cylindrical body with high accuracy by inserting a male die into a peripheral face of middle part in axial direction of the cylindrical body (material) and thrusting against it, and rotating the material at interval determined on the basis of plastic deformation of the material. CONSTITUTION:Plural grooves are formed on the inner peripheral face of a solid cylindrical material (valve body) by the following method. After engaging a notch 72 in an index groove 60, pressure is applied to an index ring 56 to thrust a male die 66 against the inner peripheral face of the material 58, and a groove is cut on the inner peripheral face of the material 58. After releasing the engagement of the notch 72 and groove 60, a ring 56 is turned to engage the notch 72 with other groove 60. By repeating these operation, for instance, eight grooves can be cut successively along circumferential direction of inner peripheral face of the material 58. In the figure, 1 indicates the cylindrical material, and 2 indicates grooves on the inner peripheral face.
