The lower end of support plate 4 further away from support plate 4 upper end closer to pipe fitting, and the upper end of medial surface is parallel to the outside wall surface of pipe fitting, with
The clamping pipe fitting consolidated during necking.Interior 521 quantity of form unit is identical with 41 " quantity of sandwich unit, form unit in every piece
521 one sandwich units 41 " of contact.Pull rod 5 " passes perpendicularly through support plate 4, and four pull rods 5 " are evenly arranged in outside internal model 52.Band
Dynamic component includes link disk 61 " and drive connector 62 ", and pull rod 5 ", linkage disk 61 " and drive connector 62 " are sequentially connected.Link disk
61 " arrange with 4 parallel interval of support plate, and 5 " both ends of pull rod are separately connected external mold 51 and linkage disk 61 ", drive the two of connector 62 "
End is separately connected the center of linkage disk 61 " and the drive system with sizing system.
The course of work of necking sizing die are as follows: drive system, which is connected and driven, drives connector 62 " along the pipe fitting axis
Movement of the line direction far from support plate 4, i.e. moving downward in attached drawing drive connector 62 " to drive linkage disk 61 " and four pull rods
5 " move downward, and the whole translation downwards under the uniform force of four pull rods 5 " of external mold 51, in the process, 51 through-hole of external mold inclines
The lateral surface of internal 521 taper of form unit in inclined-plane applies pressure, pushes interior form unit 521 mobile towards pipe fitting axis, multiple interior
Form unit 521 successively pushes the muti-piece sandwich unit 41 " being in contact with it, the internal diameter for the sandwich 4 " that muti-piece sandwich unit 41 " is formed
It gradually becomes smaller, the partial shrinkage pipe fitting of 41 " clamping face lower end of sandwich unit protrusion achievees the purpose that necking.
Entirety rise diameter sizing die entirety rise diameter sizing component include second rise core and second flaring module.Second rises core
In support plate 4, pipe fitting to be processed is sheathed on second and rises outside core, and second core that rises includes that muti-piece second rises core unit, more
Block second rises by core unit using the axis of the pipe fitting as center axis coaxially successively moving jointing, the second lateral surface for rising by core unit
For smooth surface, it is parallel to pipe fitting inner wall face, the second core unit medial surface that rises towards support plate 4 moves closer to the pipe fitting axis
Line.Second flaring module passes perpendicularly through the center of support plate 4, and second flaring module one end is tapered end, and muti-piece second rises core list
Member is disposed around the outside of tapered end, and the lateral surface of tapered end is the conical surface, and tapered end lateral surface fitting second is risen the inside of core unit
The lateral surface in face, the second flaring module tapered end moves closer to the pipe fitting axis towards 4 direction of support plate.Second flaring module
One end opposite with tapered end connects the drive system of sizing system.
Entirety rises the course of work of diameter sizing die are as follows: when drive system drives the second flaring module to move down, second
The tapered end of flaring module pushes second to rise core, keeps multiple second core units that rise mobile, and second rises core spreading, and second rises core unit
Lateral wall is bonded pipe fitting inner wall face, pushes pipe fitting globally expanding.
Be it is necessary to described herein finally: above embodiments are served only for making technical solution of the present invention further detailed
Ground explanation, should not be understood as limiting the scope of the invention, those skilled in the art's above content according to the present invention
The some nonessential modifications and adaptations made all belong to the scope of protection of the present invention.
