The invention relates to a method for producing a blind hole (10) in a metallic workpiece having at least one curved surface. One part of the material is pushed starting from approximately the horizontally extending curved tangent and from there approximately perpendicular in the direction of the material of the workpiece by means of reciprocating movement. Said method consists of the following steps: a) providing the workpiece with a matrix-type receiving element (16) for the material which is to be displaced; b) pushing the workpiece material by means of a stamp in the axial direction of the receiving element (16), said material stamped by the stamp is initially sheared in an adiabatic state and flows partially into the receiving element (16); c) removing (16) the material projecting from the receiving element. | ||||||

PURPOSE: To make the occurrence of failure during working difficult and make possible long-time cold working by forming the inside and outside circumferences of a nib to a regular hexagon. CONSTITUTION: Six small pieces 1 of nibs are combined by bringing the top bottom 8 on the inner side and allowing legs 6, 7 to contact, respectively, whereby a nib 2 of a regular hexagon on both inside and outside circumferences is formed. A bushing 3 of which the inside circumference is a regular hexagon resembling to the outside circumference of the nib 2 and the outside circumference is circular is fitted to the outer side of the nib 2. The nib 2 is cold press-fitted or shrinkage-fitted to the inner side of the bushing 3. A punch case 4 is further press-fitted or shrinkage-fitted to the outer side of the bushing 3. The above-mentioned finishing punch for bolts is combined with the small pieces 1 of nibs and is of a regular hexagon on both inside and outside circumferences of the nib. Therefore, the nib 2 is difficult to fail during cold working and permits long-time cold working without exchanging the nib 2. COPYRIGHT: (C)1981,JPO&Japio | ||||||
