Abstract
The utility model provides a steam turbine blade forging die without a die holder. Steam turbine blades require short design period and low processing cost. The steam turbine blade forging die comprises a male die, a female die and a pressing die working cavity formed by the male die and the female die, and is characterized in that when the male die and the female die are closed, the contact end surfaces of the male die and the female die are matched through concave and convex surfaces.
Description
(1) technical field
The utility model relates to turbine blade and forges the field, is specially a kind of turbine blade forging mold that does not have die holder.
(2) background technology
Existing turbine blade is to adopt prefabricated blank to carry out open type die forging forging forming on screw rod hammer or friction press, when forging forming, because side force is bigger, so blade forging is when forging forming, mould need be installed in the die holder, the pattern seat guarantees the relative position of mould, guarantees that blade forging does not misplace.When the required die holder of making trendy turbine blade and existing die holder did not match, it not only needed redesign, makes mould, needed design, making die holder simultaneously, and required design cycle of its turbine blade is long, processing cost is high.
(3) summary of the invention
At the problems referred to above, the utility model provides a kind of turbine blade forging mold that does not have die holder, and required design cycle of its turbine blade is short, processing cost is low.
Its technical scheme is such: it comprises punch, die and described punch, the formed pressing mold working chamber of die, it is characterized in that: when described punch, die matched moulds, cooperate by male and fomale(M﹠F) between the contact end face of described punch and described die.
It is further characterized in that: totally four of described contact end faces; Described four contact end faces cooperate by male and fomale(M﹠F) respectively.
After adopting said structure of the present utility model, because four contact-making surfaces of punch, die cooperate by male and fomale(M﹠F) respectively, four have been formed so respectively at the self-locking structure that presses down direction perpendicular to punch, the side force that forging forming produced, offset by male and fomale(M﹠F) respectively, so the relative position of mould can not change, can guarantee that equally blade forging does not misplace, so when making trendy turbine blade, need not to design again die holder, only need the design die holder, so required design cycle of turbine blade is short, processing cost is low.
(4) description of drawings
Fig. 1 is the utility model stereogram structural representation.
(5) specific embodiment
See Fig. 1, it comprises punch 1, die 2 and punch 1, die 2 formed pressing mold working chambers (belong to existing mature structure, do not draw among the figure), when punch 1, die 2 matched moulds, cooperates by male and fomale(M﹠F) 3 between the contact end face of punch 1 and die 2.Punch 1 and die 2 contact totally four of end faces, four contact end faces cooperate by male and fomale(M﹠F) 3 respectively.
Claims (3)
1. turbine blade forging mold that does not have die holder, it comprises punch, die and described punch, the formed pressing mold working chamber of die, it is characterized in that: when described punch, die matched moulds, cooperate by male and fomale(M﹠F) between the contact end face of described punch and described die.
2. a kind of turbine blade forging mold that does not have die holder according to claim 1 is characterized in that: totally four of described contact end faces.
3. a kind of turbine blade forging mold that does not have die holder according to claim 2 is characterized in that: described four contact end faces cooperate by male and fomale(M﹠F) respectively.
