Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
A kind of reducing die as shown in Figure 1, 2, including necking idler wheel 1, fixed bottom plate 2, necking rise mould and Power Component,
Necking rises by mould setting on fixed bottom plate 2.
In the present embodiment: the necking mould that rises includes that necking upper mold 30, internal model rise under block 31, necking external mold 32 and necking
Mould 33.Wherein:
The necking mould that rises is connected on fixed bottom plate 2 by necking upper mold 30.
Internal model rises block 31: it has the upper surface 310 being arranged concentrically and lower end surface 311, connection upper surface 310 and lower end surface
311 outer peripheral surface 312, the area of upper surface 310 are greater than the area of lower end surface 311, and outer peripheral surface 312 smoothly transits from top to bottom,
Internal model rise block 31 outer peripheral surface on offer the groove 313 vertically extended.In the present embodiment: internal model rises the upper of block 31
End face 310, lower end surface 311 are in regular polygon, and such as octagon, then outer peripheral surface 312 is the inclined-plane that multiple left and right are connected, and such as eight
Inclined-plane, the setting that groove 313 is then spaced is on four inclined-planes, as shown in Figure 3,4.
Necking external mold 32: necking external mold 32 is arranged between necking upper mold 30, necking lower die 33, and necking external mold 32 is provided with
Multiple, multiple necking external molds 32 rise internal model in block 31 is enclosed in；Multiple necking external molds enclose outer surface and the shrinkage waiting open of 32 synthesis
