The invention discloses an integral
spinning forming method of a
silicone oil
damper housing of a
crankshaft. The method comprises the following steps: a, blanking; b,
punching a center hole; c, performing
shovel spinning to increase the thickness, wherein a first
shovel spinning wheel and a second
shovel spinning wheel on a numerically controlled spinning
machine are synchronously operated to perform shovel spinning on a circular board so as to form an inner
barrel on the circular board; d, performing stretching and spinning to obtain an outer
barrel, namely,
flanging the circular board through a
flanging wheel on the numerically controlled spinning
machine, and performing spinning through a spinning flattening wheel, so as to form the outer
barrel on the circular board, wherein the outer barrel is concentric with the inner barrel; e, performing spinning to obtain teeth; and f,
machining. The integral spinning forming method of the
silicone oil
damper housing of the
crankshaft is high in adaptability; the
silicone oil
damper housing, manufactured by the method, of the
crankshaft, is high in sealing performance, easy in
quality control, and long in service life; meanwhile, a good spinning die design scheme and a good forming scheme are provided for other shovel spinning parts, stretching and spinning
flanging parts and double-
barrel shaped parts with different sizes. Therefore, the method has a great guiding significance.
