Abstract: PROBLEM TO BE SOLVED: To obtain the mass-production of forged connecting rod excellent in dimensional precision and unit wt. precision by pressing a forged blank having a bore initiator without any burr with two inserts in dies. SOLUTION: The forging blank 33 for connecting rod, having at least one of the bore initiator (a part for guiding the bore correcting) in a large end part and a small end part without any burr on the side surfaces, is forged. Then, this forged blank 33 is bodily corrected by pressing with two inserts 57, 58 in the die 55 to form the corrected forged blank for connecting rod. In such a way, the forged connecting rod shaped with the large end part, body part and small end part, is provided. Mandrels 59, 60 slidable into the inner part of holes 61, 63 formed along the axial lines of bores in the inserts 57, 58, are inserted into the bores of the blank 33 and successively, corrected. By this method, the forged blank having high precision can be mass-produced.

Abstract: PROBLEM TO BE SOLVED: To drive a power ultrasonic actuator most suitably with high reliability by correcting the frequency according to the phase change direction. SOLUTION: This device is equipped with an oscillator 3 for feeding a signal having the adjustable frequency, means 4, 5 for measuring the phase between the voltage and the current strength of the signal, and a computer 6 for determining the direction of the phase change in a cycle of preset length and calculating the correction of the frequency of the signal according to the phase change direction to apply it to the oscillator. It is applied to the driving of a power ultrasonic actuator used in various industrial equipment, particularly the one used for generating ultrasonic waves in a continuous casting ingot mold.

Abstract: PROBLEM TO BE SOLVED: To reduce the weight of a crank shaft without impairing mechanical durability by deforming an intermediate preform, forging along the axial direction of a base pipe and adjusting the lengths of crank pin parts and supporting bearing parts. SOLUTION: The intermediate preform is manufactured from the base pipe of a steel having long straight linear state and a fixed diameter with a hydroform method. This intermediate preform has a fixed length part of different diameters alternately forming the preforms for the crank pin parts 3 mutually matched and the preform for the supporting bearing parts 2 so as to become the same axis with the base pipe. The preforms are formed by inserting the base pipe into a mold having desired diameters and lengths of the supporting bearing parts 2 and crank pin parts 3. At least one of the fixed length part parallel to the supporting bearing part is displaced to the side direction. The deformed intermediate preform is forged along the base pipe direction and matched to the lengths of the crank pin parts 3 and the supporting bearing part 2.

Abstract: PROBLEM TO BE SOLVED: To optimally lubricate the whole metal to be cooled by pouring liquid lubricant to the lower part from a position where the cast material starts solidification, and making the liquid lubricant rise along the wall of a tubular metallic member by a vibration of a mold. SOLUTION: In the mold for continuous casting, the liquid lubricant is poured between the inside surface 3 of the cooled tubular metallic member 2 and the solidified outer shell 14 of the casting 16. This liquid lubricant is poured only to the position apart from the upper side end edge part 8 of the cooled tubular metallic member 2 by >=20cm. The pouring is executed through introducing pipes 18, 19 formed in the wall of the tubular metallic member 2. The introducing pipes 18, 19 are opened at the positions of holes 20, 21 formed on the inside surface 3 of the tubular metallic member 2. The holes 20, 21 are formed so that the liquid lubricant distributes in the whole periphery of the solidified outer shell 14 of the casting 16. A part of the lubricant rises along the wall of the cooled tubular metallic member 2 by the vibration of the mold 1. By this method, sufficient quantity of the liquid lubricant can rise to the position of solidification starting.
