Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the utility model further.
Raw material for the necking down of back casing neck secondary are that the discoid of magnadure material adds labor and materials, and these discoid labor and materials that add are the semi-finished product that there is taper boss structure at middle part.
As illustrated by figures 1 a-1 c, rear case of vacuum booster neck secondary stem reducing mould (hereinafter referred to as " this mould "), it comprises: cope match-plate pattern II200, lower bolster II201, press plates II202, mould pin II203, mould pin II204, die backing plate II205, die II206, die mold insert II207, upper holding pad II208, punch II209, lower support flitch II210, the dead block II211 of pier, up and down position-limit mechanism II212, mould bases outer guiding post II213, mould bases outer guiding post II214, mould bases outer guiding post II215, spring II216, stop screw II217.
The bottom of described cope match-plate pattern II200 is provided with lower bolster II201, described lower bolster II201 bottom is provided with press plates II202, described press plates II is provided with four mould pin II203 circumferentially and mould pin II204 arranged placed in the middle, described cope match-plate pattern II bottom is provided with die II206 by die backing plate II205, described lower bolster II top is provided with punch II209, described die II is provided with die mold insert II207, die mold insert II207 is detachably installed by screw, described punch II209 top is provided with lower support flitch II210, the bottom of described cope match-plate pattern II is provided with the upper holding pad II208 coordinated with lower support flitch II, described cope match-plate pattern II, lower bolster II is provided with the mould bases outer guiding post II213 being incorporated into the degree of depth for limiting cope match-plate pattern II, mould bases outer guiding post II214, mould bases outer guiding post II215, spring II216 and stop screw II217 is provided with between described upper holding pad II208 and cope match-plate pattern II, the bottom of described spring II is resisted against holding pad II208, this spring II through die backing plate II205, described punch II209 has a taper boss II for back casing neck secondary undergauge, the top of described taper boss II is planar structure II, and larger than all footpaths of back casing neck 1.38-1.4 times of the Zhou Jing of this taper boss II, at the bottom of the neck of later casing neck, neck top diameter is respectively 60mm, 50mm is example, at the bottom of the cone of design taper boss II, then 83mm can be set to during vertex of a cone diameter, 70mm, because back casing neck is step-like structure, diameter at the bottom of the neck of back casing neck is greater than neck top diameter, Given this, the diameter of this taper boss II then from the cone end to the diameter of the vertex of a cone the like design, the crossover position of taper boss II and lower support flitch II210 and the crossover position between the sidewall of taper boss II and planar structure II are provided with arc-shaped transition structure, this arc-shaped transition structure can be avoided raw material generation brittle failure or break, described die mold insert II207 has an inner fovea part II coordinated with taper boss II.Then define a forming gap II mated with product shown in Fig. 4 after closing at die II, punch II, define by this mould the semi-finished product that there is taper boss structure at a middle part.
