Abstract: PURPOSE: To produce multiple and diversified kinds of part inexpensively and easily by providing mechanisms that can adjust the position of a die from the outside of a slider in a rotary forging machine.  
     CONSTITUTION: Prior to performing of production of parts, a handle 42 projecting to the outer part of a slider 19 is rotated to rotate a geared nut 34 by way of a worm 40, a worm gear 39 and the 1st gear 38. The nut 34 rotates on the outside circumference on the 1st ram 32, and a slider 19 moves upward and downward with respect to the 1st ram 32. By the upward and downward movements of this slider 19, the position of a die 27 of the time when the 1st ram 32 reaches the top end of the 1st cylinder barrel 31 is selected in accordance with the shape of desired parts. Thence, the blank material held in the die 27 with respect to a punch 11 making precession is brought to the prescribed position corresponding to the shape of the parts by the operation of the 1st cylinder system of a two-step stroke cylinder 30, and in that position, it is locally pressed by the punch 11, whereby it is gradually deformed and the parts of a desired shape are produced.

IPC: F16L13/14
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To heighten the buckling strength of a steel pipe without enlarging the diameter by fastening and fixing one or more sleeves made of shape memory alloys, which were positioned in the longitudinal direction of the steel pipe, through heating the sleeve or through constracting the inner diameter of the sleeve. SOLUTION: A sleeve 5, which is made of one-way shape memory alloys, is installed in a steel pipe 1 in manufacture. As for the shape memory alloy, Fe-Mn-Si shape memory alloy is optimum, from the view-point of the price and easiness of application. The sleeve 5 is enlarged in its diameter in advance, it is positioned, and then it is contracted in its diameter through heating or cooling. The shape memory alloy whose effect can stably be obtained up to a temperature of 300 deg.C, or a predictable maximum of the environment of its use, will suffice for the purpose. On the other hand, in order to heighten the buckling strength, a steel pipe having the outer diameter of 73mm is used as a drill pipe. In order to heighten the joint strength, inner/outer upset working is applied to the end of this steel pipe at first, and then the steel pipe undergoes quench-and-temper treatment. With this, one can obtain a steel pipe which has a node that is effective in shorten the column length and which has high buckling strength for a long column.
