Description
Technical field
The invention belongs to flat-die forging technical field, particularly relate to a kind of combination loose tool and manufacturing process thereof of a contour forming, for the making of the finish forge blocking base of nozzle body class part various in Aeroengine Products.
Background technology
Modern Engine nozzle body class part is the strength member of engine, and such part of designing requirement in early stage is cast form; But the intensity due to foundry goods can not meet the overall performance requirement of high thrust-weight ratio engine, therefore change in design produces such part for adopting precision plastic forming technology, to reach the object promoting its performance indications; The nozzle body class part using the manufacture of precision plastic forming technology instead remains the requirement of former casting project organization substantially.Because nozzle body class design of part is complicated, adopt conventional Forging Technology base forming process many, number of molds is many, and stock utilization is low.
Abroad, its manufacturing technology belongs to high sophisticated technology field, and forming technique privacy degrees is high.At home, though the net-size forging of current structure of the same type is succeeded in developing, because its complex structure, dimensional accuracy are high, manufacture difficulty is very large, causes the qualification rate of net-size forging very low, only has about 25%; Adopt common forging and molding mode base, because many key technical problems are not resolved, cause final qualification rate also only to have about 36%.Complicated design of part, accurate dimensional requirement, II grade of net-size forging standard, determines the difficulty of such machine parts'precise plastic forming technology.
Summary of the invention
For prior art Problems existing, the invention provides a kind of combination loose tool and manufacturing process thereof of a contour forming; This manufacturing process can realize completing the base shaping simultaneously of three kinds of structures in a combination loose tool, improves operating efficiency and product percent of pass.
To achieve these goals, the present invention adopts following technical scheme, a kind of combination loose tool of a contour forming, comprises the overcoat with endoporus, interior lower gasket ring, interior upper pad one ring and interior upper pad two ring; The loose tool that described overcoat, interior lower gasket ring and interior upper pad one ring composition first time is shaped, in described in the loose tool that first time is shaped, lower gasket ring is arranged on the bottom of overcoat endoporus, interior upper pad one ring is arranged on the top of overcoat endoporus, and described interior upper pad one ring is corresponding with the profile of first time shaping material base with the die cavity that interior lower gasket ring forms jointly; The loose tool that described overcoat, interior lower gasket ring and interior upper pad two ring composition second time is shaped, in described in the loose tool that second time is shaped, lower gasket ring is arranged on the bottom of overcoat endoporus, interior upper pad two ring is arranged on the top of overcoat endoporus, and described interior upper pad two ring is corresponding with the profile of the die cavity that interior lower gasket ring forms jointly and blocking blank.
The outside dimension of described interior upper pad one ring, interior upper pad two ring is identical, and corresponding with the hole size of overcoat.
For the ease of being taken out by the blocking blank after shaping, described interior upper pad two ring is made up of two semi-rings.
The manufacturing process of the combination loose tool of the contour forming described in employing, comprises the steps:
Step one: pulling
By the pulling of the two ends of raw material bar to required size and structure;
Step 2: first time is shaped
Interior lower gasket ring is put into the bottom of overcoat endoporus, then the bar that two ends pull out is put into the die cavity of upper pad one ring, more together put into the top of overcoat endoporus together with interior upper pad one ring, carry out first time forging and molding, form the material base that is shaped for the first time;
Step 3: melt down heating
First time shaping material base is taken out from first time shaping loose tool, then carries out melting down heating;
Step 4: second time is shaped
First time shaping material base after heating is put into the die cavity of gasket ring under jacket internal, the upper rear interior upper pad two ring set being entered first time shaping material base puts the top of overcoat endoporus into, carries out second time forging and molding, forms blocking blank.
Beneficial effect of the present invention:
The present invention revolutionizes a traditional fiery mold forming technique, changes the shaping mode of multi-mould multiple working procedure; Achieve and complete three kinds of structures base forming technology simultaneously in one set of die, easily ensure structure and the dimensional requirement of the part of final precision forging.
The manufacturing process of combination loose tool of the present invention is adopted to substantially increase raw-material utilization rate, save the consumption of from one piece, improve the qualification rate of final fine forge piece product, reduce cost, add income, drastically increase aero-engine structural member fine forging technology level; And save a large amount of subsequent mechanical labor contents, reach the final forming requirements of fine forge piece, improve the service life of finish forge mould.
