Description
Technical field
The present invention relates to a kind of forging method, is the multi-ram forging for being related to a kind of main flange valve body forging of band specifically
Manufacturing process.
Background technology
At present, valve body forging uses two kinds of forming modes, i.e., common die forging and the multi-ram forging of horizontal parting more.Common mould
During forging, overlap on die joint be present, while lateral aperture and upright opening can not be forged, forge weight is big, and waste of material is more.It is horizontal
Although the multi-ram forging of mould-dividing mode can forge lateral aperture and upright opening, main flange can not be forged, causes forging to machine
Pts wt is big afterwards, and installation is more difficult.
The content of the invention
For above-mentioned deficiency of the prior art, the present invention provide it is a kind of it is rational in infrastructure, safety coefficient is high, easy to operate
Multi-ram forging manufacturing process with main flange valve body forging.
The technical solution used in the present invention is：
A kind of multi-ram forging shaping dies of the main flange valve body forging of band,
Including lower mould, lower mould top is provided with left mould and right mould；
The left mould is connected by left side waling stripe with left side horizontal cylinder；
The right mould is connected by right side waling stripe with right side horizontal cylinder；
Mould is provided with above the left mould and right mould；
The upper mould is connected with upper mould upper padding plate；Upper mould upper padding plate is connected with dynamic beam；
Through hole is provided with the middle part of the upper mould；
Centre bore is provided with the middle part of the upper mould upper padding plate；
Vertical cylinder is provided with above the upper mould upper padding plate；
The vertical cylinder bottom is connected with upper punch；
The upper die and lower die form closed cavity with left mould and right mould and upper punch.
A kind of multi-ram forging manufacturing process of the main flange valve body forging of band, comprises the following steps：
Left mould, right mould matched moulds and carry out pressurize in the presence of horizontal cylinder respectively；
In the die cavity that blank is put into lower mould and left mould, right mould are formed；
Upper mould is run downwards under dynamic beam action；And blank is suppressed；
After upper mould contacts with left mould, right mould, upper punch starts to run downwards；And blank is suppressed；
Upper punch runs to out of service behind setting position；
Upper punch is run up in the presence of foundation, foundation backhaul；
The backhaul in the presence of horizontal cylinder respectively of left mould, right mould；Left mould is moved to the left, and right mould moves right；
Forging can be taken out from drag chamber.
The beneficial effect of the present invention compared with the prior art：
The multi-ram forging manufacturing process with main flange valve body forging of the invention, can a forging go out main flange and upright opening,
Forge weight is reduced, forging efficiency is improved, improves forging precision, reduce production cost.
