Abstract

A kind of upset prefabricating blank crossed bent blades forging and use, described one end crossing the upset part that bent blades forging uses is two column structures (1), described column structure (1) be plane structure up and down, the both sides of column structure (1) are arc structure, and the thickness of column structure (1) presses blade tenon demand 15%-20% deformation amount controlling; The arc structure of described column structure (1) is by 45 ° of inclined-planes and bending column structure I I (2), the plane structure of column structure (1) is by switching fillet and bending column structure I I (2), the upset part crossing the use of bent blades forging described in the utility model fundamentally solves the generation of deflection issues, effective solution because of upset part head, bar portion is asynchronous with contacting dies and the deflection produced, also make forging deformation process more rationally controlled simultaneously, and reduce raw materials consumption about 20%, there is comparatively huge economic value and social value.

Description

A kind of upset part crossed bent blades forging and use

Technical field

The utility model relates to structural design and the applied technical field of upset part, specifically provides a kind of upset part crossed bent blades forging and use.

Background technique

It is straight circular cylinder type structure that tradition crosses the upsetting die that bent blades forging uses, when carrying out bent blades blocking can because of the head of upset part, bar portion is asynchronous with contacting dies and deflect, cause finish-forging part local to lack and expect and be not fully filled.General solution is for increasing upset part bar portion diameter, after upset part is deflected, unnecessary material also can be full of mold cavity, and this technological method not only blade amount of deformation can not get effective control, reduce die life, also can cause raw-material larger waste simultaneously.

People urgently wish to obtain the excellent upset part crossing the use of bent blades forging of a kind of technique effect.

Model utility content

Order of the present utility model is to provide a kind of upset part crossed bent blades forging and use.

Described one end crossing the upset part that bent blades forging uses is two column structures 1, described column structure 1 be plane structure up and down, the both sides of column structure 1 are arc structure, and the thickness of column structure 1 presses blade tenon forging demand 15%-20% deformation amount controlling; The arc structure of described column structure 1 is by 45 ° of inclined-planes and bending column structure I I2, the plane structure of column structure 1 is by switching fillet and bending column structure I I2, described bending column structure I I2's is plane structure up and down, the both sides of column structure 1 are arc structure, the tortuosity of described bending column structure I I2 is identical with bending blade degree, and the thickness of bending column structure I I2 presses blade blade demand 35%-45% deformation amount controlling.The other end of bending column structure I I2 is connected with location column structure III 3, described location column structure III 3 be plane structure up and down, both sides are arc structure, and the thickness of locating column structure III 3 meets forging positioning boss 35%-45% amount of deformation.

The A thickness size of column structure 1 presses blade tenon demand 15%-20% deformation amount controlling, and director's C degree of column structure 1 subtracts 1.0mm design according to forging head sizes, and F place is blade press-bending locating face (without withdrawing pattern).

D, E place circular arc of bending column structure I I2 crosses crook profile design according to blade, meet blade blade 35%-45% amount of deformation, B place meets forging positioning boss 35%-45% amount of deformation, and the overall length G size crossing the upset part that bent blades forging uses will be longer than head formation work step part overall length.

Tradition, by increasing the method for upset part bar portion diameter, can not avoid upset part blocking to deflect.The upset part structure of present patent application, according to blade forging profile design, meets the requirement of blade forging molding different piece amount of deformation., produce at blocking, identical warp architecture is more fitted Preform Die surface meanwhile, and upset part will, because contact priority with forging die, cause deflection to be scrapped.

The upset part crossing the use of bent blades forging described in the utility model fundamentally solves the generation of deflection issues, effective solution because of upset part head, bar portion is asynchronous with contacting dies and the deflection produced, also make forging deformation process more rationally controlled simultaneously, and reduce raw materials consumption about 20%, there is comparatively huge economic value and social value.
