Patrix is provided with above described left mould and right mould;
Described patrix is connected with patrix upper padding plate; Patrix upper padding plate is connected with dynamic beam;
Through hole is provided with in the middle part of described patrix;
Centre bore is provided with in the middle part of described patrix upper padding plate;
Vertical cylinder is provided with above described patrix upper padding plate;
Described vertical cylinder bottom is connected with upper punch;
Described upper die and lower die and left mould and right mould and upper punch form enclosed cavity.
With a multi-ram forging manufacturing process for main flange valve body forging, comprise the steps:
Zuo Mo, right mould be matched moulds carry out pressurize under the effect of horizontal cylinder respectively;
The die cavity that blank puts into counterdie and left mould, right mould is formed;
Patrix runs downwards under a beam action; And blank is suppressed;
After patrix contacts with left mould, right mould, upper punch starts downward operation; And blank is suppressed;
Upper punch is out of service after running to desired location;
Upper punch upwards runs under a beam action, foundation backhaul;
The backhaul under the effect of horizontal cylinder respectively of Zuo Mo, right mould; Left mould is moved to the left, and right mould moves right;
Forging can be taken out from counterdie die cavity.
The beneficial effect of hinge structure of the present invention:
The multi-ram forging manufacturing process of the main flange valve body forging of band of the present invention, a forging can go out main flange and upright opening, reduces forge weight, improves forging efficiency, improves forging precision, reduce production cost.

Detailed description of the invention
Referring to drawings and Examples, the present invention will be described in detail:
Accompanying drawing 1-8 is known, a kind of multi-ram forging shaping dies with main flange valve body forging,
Comprise counterdie 1, counterdie 1 top is provided with left mould 4 and right mould 5;
Described left mould 4 is connected with left side horizontal cylinder 2 by left side waling stripe 3;
Described right mould 5 is connected with right side horizontal cylinder 2 by right side waling stripe 3;
Patrix 8 is provided with above described left mould 4 and right mould 5;
Described patrix 8 is connected with patrix upper padding plate 6; Patrix upper padding plate 6 is connected with dynamic beam;
