Abstract

PURPOSE: To carry out two process on the same lower die and accomplish final curling without using air cylinder, by using the lower die of preliminary curling, fixing the base with a cutter to the lower end of a rod which is fitted, in a vertically slidable manner, to an elevatable pressurizing base and machine frame, and providing an air spring between two bases.
CONSTITUTION: By lowering the pressure of an air spring 18, for instance, inside and outside panels Wb, Wa of an automobile door are overlapped and set in a lower die 2. When a cylinder 28 is extended, the power doubling means causes a preliminary curling; blade 19 to push a flange part F, thereby preliminarily curling, about 45° inside. Then, a motor 11 is rotated in the normal direction to turn a nut 6, and a push rod 8 and a pressurizing base 9 fixed thereto are lowered from the position shown by chain line. At this time, a guide rod 14 and a base 15 are also lowered, and when a final curling blade 17 abuts against the flange part F, the spring 18 is compressed, so that a gap is created between a collar 14a and a boss 9a. This is detected by a sensor, and the motor 11 is stopped, and high pressure air is sent to the spring 18 at the same time. As a result, the base 15 is pressed down hard, and the blade 17 folds the flange part F completely.
