Abstract
PURPOSE: To obtain the highly accurate, lightweight and compact forming machine by which the parallelism of both rolls with each other is always secured by horizontally layably providing an arm which fits into the free end of the main roll and supports this and making the elevating operation of a pinch roll oscillating motion.
CONSTITUTION: The pressure contact degree of the pinch roll 10 mounted with an elastic material to a main roll 1 is adjusted to meet the thickness, hardness, etc. of the work by rotating the handle 22 at the end of a shaft 20 and elevating support rods 14a, 14b. At this time, the advacning and retreating of the foregoing both support rods are synchronized to maintain the parallelism of the rolls 1, 10. Next, the bearing part 6 of the arm 5 of an air cylinder 9 is fitted into the small-diameter part 4 of the roll 1 and is held thereby. Next, the shaft 16 which is offcenter from support rods 15a, 15b is turned by a rotary actuator 21 to let the roll 10 make pressure contact to the roll 1. The formed product having been inserted and bent between both rolls is drawn out by lowering the roll 10 and horizontally laying the arm 5. Here, collars are mounted to the roll 1, whereby the formed products of various curvatures may be obtained.
