Specific implementation mode
The invention will be 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
The mould that rises setting is 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 to by necking upper mold 30 on fixed bottom plate 2.
Internal model rises block 31：It has the upper surface 310 being arranged concentrically and lower face 311, connection upper surface 310 and lower face
311 peripheral surface 312, the area of upper surface 310 are more than the area of lower face 311, and peripheral surface 312 smoothly transits from top to bottom,
Internal model rise block 31 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 face 311 are in regular polygon, and such as octagon, then peripheral surface 312 is the inclined-plane that multiple left and right are connected, 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
The shape of product 4 is consistent, is provided on the inner surface of necking external mold 32 and 313 matched protrusion 320 of groove, protrusion 320
It fits with groove 313, the setting object of certain groove 313 and protrusion 320 can also exchange.When internal model rises by block 31 from the top down
When sliding, internal model rises by the promotion necking of block 31 external mold 32 to outside movement, so that tensioner shrinkage waiting open product 4, makes shrinkage waiting open product 4 exist
It will not arbitrarily be swung during necking.
The peripheral surface of necking lower die 33 gradually extends inwardly from top to bottom, can play the role of guiding module.
