Description
Technical field
The utility model relates to the technical field of mould structure, is specially a kind of bilateral flange type mould for forging.
Background technology
Bilateral flange type forging, due to the reasons in structure of the stage casing indent of outer ring surface, after upper die and lower die straight forming, namely cannot the demoulding, prior art adopts normal direction forging or has forged the unnecessary surplus of aft-loaded airfoil shaping.Normal direction forging is higher to mould, forging required precision, and technics comparing is complicated, and cost of manufacture is large, and production efficiency is low; And it is shaping to forge aft-loaded airfoil surplus, stock utilization is lower, and after processing, material internal streamline is cut off, and causes bilateral flange type forging local strength to reduce, can not adapt to high strength demand.
Summary of the invention
For the problems referred to above, the utility model provides a kind of bilateral flange type mould for forging, it makes the bilateral flange forge piece of the stage casing indent of outer ring surface can one-shot forming, and mould structure is simple, technique is simple, make that the efficiency of machine-shaping is high, cost is low, and the intensity of product after machine-shaping is high.
A kind of bilateral flange type mould for forging, its technical scheme is such: it comprises patrix, counterdie, it is characterized in that: it also comprises intermediate die, described intermediate die is specially circulus, described intermediate die is formed by the intermediate module split of at least two sections of arc-shapeds, the shape of the inner ring surface of described intermediate die is the inner ring surface of the stage casing female parts of forging to be formed, the shape of the upper surface of described intermediate die is the upper surface of the stage casing female parts of forging to be formed, the lower surface of described intermediate die comprises inner side die joint, location, outside end face, the shape of described inner side die joint is the lower surface of the stage casing female parts of forging to be formed, the outer ring surface of described intermediate die is specially the assembling annuli arrangement inwardly shunk from top to bottom, the region that described counterdie corresponds to the stage casing female parts of forging to be formed is provided with the location anchor ring inwardly shunk from top to bottom, it is described that inwardly the least significant end of location anchor ring of contraction and the link position place of the cavity portion of below are provided with positioning step from top to bottom, the assembling annuli arrangement of described intermediate die is fitted the location anchor ring of described counterdie, location, the outside end face of the lower surface of described intermediate die is close to described positioning step and is installed.
It is further characterized in that:
The least significant end of the described location anchor ring inwardly shunk from top to bottom is lower than the top initiating terminal of the link position of the cavity portion of described below, described positioning step is from the layout that is inclined upwardly outside to inside, location, the outside end face of the lower surface of corresponding described intermediate die is the layout that is certainly inclined upwardly outside to inside, this structure guarantees the accurate positioning of intermediate die, can not be moved;
Described intermediate die is formed by the intermediate module split of two sections of arc-shapeds, can separate fast after two sections of intermediate modules guarantee the demoulding, takes out shaped article, guarantees production efficiency.
After adopting technique scheme, before forging, the intermediate die that split is formed is placed in counterdie, because counterdie is designed with positioning step, after combination, intermediate die may be stuck in the specified location of positioning step, during forging, material is placed in mold cavity, by the pressure of patrix, material is pressed in die cavity, after completing, intermediate die and forging as a whole, assembling annuli arrangement due to described intermediate die is fitted the location anchor ring of described counterdie, intermediate die and lower intermode is made to have certain draft angle, therefore can the demoulding smoothly, after the demoulding, intermediate die is formed by the intermediate module split of at least two sections of arc-shapeds, can freely separate, and then bilateral flange forge piece global formation, it makes the bilateral flange forge piece of the stage casing indent of outer ring surface can one-shot forming, and mould structure is simple, technique is simple, make the efficiency of machine-shaping high, cost is low, and the intensity of product after machine-shaping is high.

Detailed description of the invention
A kind of bilateral flange type mould for forging, see Fig. 1 ~ Fig. 5: it comprises patrix 1, counterdie 2, intermediate die 3, intermediate die 3 is specially circulus, intermediate die 3 is formed by intermediate module 4 split of at least two sections of arc-shapeds, the shape of the inner ring surface 5 of intermediate die 3 is the inner ring surface of the stage casing female parts of forging to be formed, the shape of the upper surface 6 of intermediate die 3 is the upper surface of the stage casing female parts of forging to be formed, the lower surface of intermediate die 3 comprises inner side die joint 7, location, outside end face 8, the shape of inner side die joint 7 is the lower surface of the stage casing female parts of forging to be formed, the outer ring surface of intermediate die 3 is specially the assembling annuli arrangement 9 inwardly shunk from top to bottom, the region that counterdie 2 corresponds to the stage casing female parts of forging to be formed is provided with the location anchor ring 10 inwardly shunk from top to bottom, the least significant end of location anchor ring 10 of inwardly shrinking from top to bottom and link position 11 place of the cavity portion of below are provided with positioning step 12, the assembling annuli arrangement 9 of intermediate die 3 is fitted the location anchor ring 10 of counterdie, location, the outside end face 8 of the lower surface of intermediate die 3 is close to positioning step 12 and is installed.
The least significant end of the location anchor ring 10 inwardly shunk from top to bottom is lower than the top initiating terminal of the link position 11 of the cavity portion of below, positioning step 12 is from the layout that is inclined upwardly outside to inside, location, the outside end face 8 of the lower surface of corresponding intermediate die 3 is the layout that is certainly inclined upwardly outside to inside, this structure guarantees the accurate positioning of intermediate die 3, can not be moved;
