Abstract

PURPOSE:To enable diversified motions due to a double eccentric sleeves by locating the spere formed at the nose of rocking shaft levers which slide on its midpoint, installing sliders sliding in the longitudinal direction on both ends of the levers and inserting eccentric shafts in those sliders. CONSTITUTION:In the rocking die forging machine guided with the backside and spherical sheet 5 of an upper die 1 and projected the rocking shaft 6 on the rock, plural eccentric shafts 36, etc., are installedon a fixed platen 3 enclosed with the rocking shaft. At the nose of the rocking shaft the spere and the levers 31, 32 slided at the midpoint are located and sliders 34 which are slided longitudinal and held are installed on both ends of the levers. The abovementioned eccentric shafts are fitted so as to rotate freely onto the sliders. Circular motion, rectilinear motion, epicycloidmotion, spiral motion, synthesis of sinusoidal motion and other motions are performed by the various combination that each of the phases and number of revolution of the eccentric shafts 35, etc., are brought into synchronism equally or the shaft of one side is stopped and so on. Thus the driving system is simplified and the diversified motions are gained by the double eccentric sleeve.

As shown in Publication No. 50207, the upper mold is attached to the outer surface of a mold holder whose back surface is formed of a part of a spherical surface, and this mold holder is attached to a spherical seat fixed to the machine frame side. , whose back surface is swing-guided, and a shaft located at the center of the back surface and protruding from the opposite side of the upper mold is supported by an eccentric shaft hole in the inner sleeve of the double eccentric sleeve. Moreover, this inner sleeve is supported by the inner surface of the eccentric bearing of the outer sleeve in this double eccentric sleeve. Then, this outer sleeve is rotated at a reduced speed by a motor, and this inner sleeve is rotated through a speed change mechanism.

Therefore, in such an oscillating forging machine, the relative rotational direction and rotational speed of the inner and outer sleeves are determined by selecting the speed change mechanism, and as a result, the lower mold can be partially pressed against the upper mold in sequence. The molding load can be reduced. In other words, although a large forming force can be obtained with a constant forming load, in an oscillating forging machine equipped with such a double eccentric sleeve, the type of motion of the upper die is the same as that of the double eccentric sleeve. It is configured by the combination of the rotational speed and relative rotational direction of the base and sleeve, as shown in Figure 4 (1).
Only four types of oscillating motion are possible: ) circular motion, (2) linear motion, (3) ebicycloid motion, and (4) spiral motion.

16, the oscillator 8 is displaced by a reciprocating motion of 10° 12 during plunging, and therefore the oscillating shaft 6 of 11 is oscillated, so that the movement is smaller than the movement of the oscillating shaft of a conventional double eccentric sleeve. Diversification can be achieved.

However, in the proposed oscillating forging machine, since motion is imparted to the oscillating shaft through oil, the drive is delayed and cannot be increased in speed, and also requires hydraulic piping and valves. This may also cause problems such as oil leakage. Another problem is that the forging machine becomes expensive due to the hydraulic system equipment.
