Background technology
High-strength tenacity, light weight are one of important development trend of Aero-Space class part; Particularly key stressed member not only requires part to have good shape and size precision, also requires its interior microscopic tissue good; Grain size is evenly tiny, and streamline is along part geometry contoured profile etc.For the Aero-Space class part of thin-wall complicated muscle class, adopt traditional machining process stock utilization low, long processing time, production efficiency is low, and is not easy to satisfy the mechanical property requirements of part; Adopt the technology of hot investment casting to be prone to cause the part internal structural flaw, percent defective is high, and mechanical property is satisfied etc.; Adopt common die forging, the thin-wall complicated muscle filling difficulty that is shaped, be easy to generate be not fully filled, forming defects such as folding, can't meet the demands.Especially for the part of asymmetric complex-curved muscle class, connect and intersection more is prone to produce folding at its curved surface, defective such as be not fully filled.Therefore, must adopt effective measures and rational forging and molding mould, qualified asymmetric complex-curved muscle part could be shaped.
Summary of the invention
The objective of the invention is in order to solve the part of existing forming technology for asymmetric complex-curved muscle class; In the problem that curved surface connects and intersection is prone to the generation folding and is not fully filled of part, and then a kind of mould that utilizes the active damping piece to control asymmetric complex-curved muscle forging forming is provided.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: the mould that utilizes the active damping piece to control asymmetric complex-curved muscle forging forming comprises heat insulation backing plate, silicate aluminum board, asbestos board, heating die sleeve, punch heating plate, punch, a plurality of heating porcelain tube and resistance wire, combined die, die backing plate, heating backing plate and following heating plate; Said heating die sleeve, heating backing plate, following heating plate and heat insulation backing plate are fixedly mounted on the hydraulic press lower table from top to bottom successively; Said combined die and die backing plate from top to bottom are fixedly mounted in the heating die sleeve successively; Combined die is provided with the overlap storehouse; Said punch heating plate is fixedly mounted on the hydraulic press upper table; Punch is fixedly mounted on the punch heating plate; The profile of said punch is corresponding with the profile of combined die and form die cavity, and asymmetric complex-curved muscle forging is placed in the die cavity, and the surface of said heating die sleeve is enclosed with silicate aluminum board and asbestos board from inside to outside; Be provided with a plurality of heating porcelain tubes and resistance wire in said heating die sleeve, punch heating plate and the following heating backing plate, each heating porcelain tube and resistance wire all are connected with external power source; Have two release discharge gates on the said punch, each release discharge gate offer the position all be positioned at asymmetric complex-curved muscle forging the dowel of picking up the ears accordingly directly over; Said mould also comprises the active damping piece; Have bad arc shoulder hole on the said punch; Bad arc shoulder hole offer the position be positioned at asymmetric complex-curved muscle forging the circular arc muscle directly over; The cross-sectional area of the upper end hole of said bad arc shoulder hole is less than the cross-sectional area of following stomidium, and said active damping piece is slidingly mounted in the following stomidium of bad arc shoulder hole, and the height of said bad arc shoulder hole is less than the degree of depth of the following stomidium of bad arc shoulder hole; Have the hole of passing through of the little drift of hydraulic press on the said punch heating plate, the little drift of said hydraulic press to pass through the hole corresponding with bad arc shoulder hole.
The present invention compared with prior art has following beneficial effect: the present invention increases the release discharge gate and increases the active damping piece through suitable position on punch, with control each several part metal flow resistance.The present invention is based on law of minimum resistance and change the resistance of each gusset joint metal flow of adjustment, the resistance size of metal flow is reached unanimity, thereby when filling, can not produce folding and defective such as be not fully filled because of each several part thin-walled muscle metal flow speed is different; And, equipment tonnage is reduced greatly through increasing the mobile filling that release discharge gate and active damping piece moving up and down in the following stomidium of bad arc shoulder hole promote metal, and cut down the consumption of energy, have the better economic environmental benefit.
