Cavity plate 2 moves, until the bottom surface of intermediolateral column flushes realization molding with the inner cavity top surface of base lower cavity die 2, bar is pressed into base
After expecting shape, base upper male mould 1 is moved upwards, and returns to initial position, and ejector beam 3 moves upwards, and pushes backing plate 4 and band is started building
Part moves upwards, and workpiece is ejected lower cavity die, workpiece is taken out, completes a working cycles.
5th step：Sub-material will make the workpiece of base, be put into axis horizontal in two halves circle clamp, workpiece rotation makes work
The material of part left-right parts is evenly distributed, can be full of entire type chamber convenient for material when finish-forging forming.Sub-material is also known as had a waistline, and is pinched
Waist is the process often having in forging forming, and details are not described herein, in the forging and molding of conventional belt handle flanged ball valve valve body forging
Also there is the step in technique.
6th step：Finish-forging forming, 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 move toward one another the left half module closed up, after closing up, right half with right half module 9
Mould is locked.Later, while stamp forging hydraulic press master cylinder drives finish-forging upper male mould 5 to move downward, oil cylinder under stamp forging hydraulic press
Drive finish-forging lower punch 6 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 shape, 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.
