In the pillar 1d that cylinder 1b outer walls extend laterally, and cylinder 1b flushes with pillar 1d bottom surface.Cylinder 1b and pillar 1d bottom surface
Matched with the upper surface of preformed workpiece, preformed workpiece carries the blank of handle flange.Conical lower portion 1c is used for preform work
The intermediate cavity of part.
The inner chamber of base lower cavity die 2 is divided into die cavity top 2a and die cavity bottom 2b, die cavity top 2a sections and intermediolateral column
Bottom surface is matched, and the workpiece of handle flange blank is carried for preform.Die cavity top 2a height is more than conical lower portion 1c height
Degree, die cavity bottom 2b is cylindrical hole, and cylinder 1b, conical lower portion 1c, cylindrical hole are coaxially disposed, cylinder 1b, cylindrical hole, conical bottom
Portion 1c, pillar 1d cross-sectional area successively decrease successively.Backing plate 4 is located at the intracavity bottom of base lower cavity die 2, and ejector beam 3 is from bottom to top
It is against through lower cavity die 2 on backing plate 4, base upper male mould 1 moves towards base lower cavity die 2, until under the bottom surface and base of intermediolateral column
The inner chamber top surface of cavity plate 2, which flushes, realizes matched moulds, and after component shaping, base upper male mould 1 moves upwards, and ejector beam 3 promotes backing plate 4 simultaneously
Drive workpiece to move upwards, realize the demoulding.
As shown in Fig. 5-Fig. 7, finisher is mainly by finish-forging upper male mould 5, finish-forging lower punch 6, die holder 7, left half module 8 and the right side
Half module 9, finisher is integrally symmetrical.Finish-forging lower punch 6 is in shaft-like, stretches into left half module 8 and right half through die holder 7 from bottom to top
In the cavity that mould 9 surrounds.After left half module 8 closes up with the right move toward one another of half module 9, while finish-forging upper male mould 5 moves downward, finish-forging
Lower punch 6 moves upwards, final forming belt handle flanged ball valve valve body forging.
Left flange a is shaped by finish-forging upper male mould 5, left half module 8 and right half module 9, and right flange b, handle flange d are by left half module 8
Shaped with right half module 9, intermediate cavity c is shaped by finish-forging lower punch 6, and after component shaping, finish-forging upper male mould 5, finish-forging lower punch 6 are same
When return to initial position after, left half module 8 and right half module 9 return to initial position.

Second step：Blanking, by blanking dividers lattice.
3rd step：Heating, will be put into heating furnace by bar good under specification, is come out of the stove after being heated to initial forging temperature.
4th step：Base, the bar come out of the stove is put into the base lower cavity die 2 of base mould, base upper male mould 1 is towards under base
Cavity plate 2 is moved, until the bottom surface of intermediolateral column flushes with the inner chamber top surface of base lower cavity die 2 and realizes matched moulds, bar is pressed into base
After expecting shape, base upper male mould 1 moves upwards, returns to initial position, and ejector beam 3 moves upwards, promotes backing plate 4 and band is started building
Part is moved upwards, and workpiece is ejected into lower cavity die, takes out workpiece, completes a working cycles.
5th step：Sub-material, also known as have a waistline, the workpiece of base will be made, be put into axis horizontal in two halves circle clamp, work
Part rotate, complete sub-material, i.e., had a waistline in workpiece loins position, make the material of workpiece left-right parts evenly distributed, be easy to finish-forging into
Material can be full of whole die cavity during shape.It is the process often having in forging forming to have a waistline, and be will not be repeated here, in conventional belt handle method
Also there is the step in the forging and forming technology of blue ball valve body forging.
6th step：Finish-forging shapes, and the workpiece that sub-material is completed is put on the finish-forging lower punch 6 of finisher, stamp forging hydraulic press
Left and right die cylinder to intermediary movements, drive left half module 8 to close up with the right move toward one another of half module 9, left half module after closing up, right half
Mould is locked.Afterwards, while stamp forging hydraulic press master cylinder drive finish-forging upper male mould 5 moves downward, oil cylinder under stamp forging hydraulic press
Drive finish-forging lower punch 6 to move upwards, final forming belt handle flanged ball valve valve body forging, left flange a by finish-forging upper male mould 5,
Left half module 8 and right half module 9 are shaped, and right flange b, handle flange d are shaped by left half module 8 and right half module 9, and intermediate cavity c is by finish-forging
Lower punch 6 shapes, and after component shaping, first returns to initial position simultaneously by finish-forging upper male mould 5, finish-forging lower punch 6, then by left half
Mould 8 and right half module 9 return to initial position, finally take out workpiece, complete a working cycles.
