工-SHAPED SILICONE OIL DAMPER HOUSING AND INTEGRAL SPIN FORMING METHOD THEREFOR

WIPO Patent Application WO/2018/107636

A1

A工-shaped silicone oil damper housing and an integral spin forming method therefor. A工-shaped silicone oil damper housing structure comprises a spoke (24) and an annular recess provided at the outer periphery of the spoke, the annular recess having a bottom plate (25), an inner cylinder (26) and an outer cylinder (27), the sectional structure of the inner cylinder (26) and the spoke (24) forming a工-shaped structure which can be of a symmetric type or an asymmetric type, the spoke (24) being provided inside the inner cylinder and not in the same plane as the bottom plate. The integral spin forming method for a工-shaped silicone oil damper housing comprises the following steps: a) blanking; b) forming a central hole by punching; c) forming a boss by shoveling and spinning; d) spin bending; e) spin flanging; and f) preparing a finished product by machine processing. The spoke of the工-shaped silicone oil damper housing is in a position which can be adjusted up and down, according to requirements，to fit to each component of an engine, such that the engine has a more compact structure; the fitting to the engine satisfies the requirements of flexible design.
