Abstract
A kind of aircraft abnormal shape sheet metal part hydroforming process method of the present invention, belongs to Aircraft Sheet Metal Parts manufacturing technology field.The technical scheme is that：Rubber pocket hydroforming die is placed on hydraulic press workbench；Part blank is placed on rubber pocket hydroforming die, is positioned on rubber pocket hydroforming die part blank with mushroom pin；Hydraulic press is started, applies the pressure of 8-10MPa to the part blank on rubber pocket hydroforming die, part blank is carried out by rubber pocket hydroforming die preforming；Hydraulic press is started again, part semi-finished product are applied with the pressure of 20MPa, part semi-finished product and rubber pocket hydroforming die type face is made to be bonded completely, forms finished part.It is an advantage of the invention that solving the problems such as domestic air mail circle abnormal shape sheet metal part manufacturing cycle length, unstable product quality, severe working environment, the rapidly and efficiently molding of special-shaped sheet metal part is realized.
Description
Technical field
A kind of aircraft abnormal shape sheet metal part hydroforming process method of the present invention belongs to Aircraft Sheet Metal Parts manufacturing technology neck
Domain.
Background technology
In airplane parts, special-shaped sheet metal part is largely used.The special-shaped sheet metal part size having is larger, installation site
It is more special, in order to reinforce the self-strength of such part, some reinforcing ribs are specially made on part.It is commonly called as " corrugated plating ".
Such part is wide in variety, and specification is also more.Hereafter referred to collectively as special-shaped sheet metal part.Such abnormal shape sheet metal part generally use is
The process of explosive forming.The mold of explosive forming adds iron powder using epoxy plastics, is made by handwork using model.Mold
It is using and is being easily damaged in handling process, needing frequent repairing die.Affect the manufacturing cycle of part.After explosive forming
Part is influenced by manufacturing process, and local pad pasting effect is poor, and type face is of poor quality.Need a large amount of schools type by hand.The product system of causing
Make period length, unstable product quality, the problems such as dangerous high, working environment is severe.It is difficult to meet research and production needs.Cheng Liao
Bottleneck problem in airplane parts manufacturing process.In order to solve this problem, it is badly in need of a kind of new moulding technique.
Invention content
The purpose of the present invention is to solve in special-shaped sheet metal part manufacturing process, die face is fragile, molding effect
Difference, period are long, the severe disadvantage of low production efficiency, working environment.It realizes with a kind of through hydraulic press to part hydro-forming
Process completes the manufacture of special-shaped sheet metal part.The groundwork of the present invention is produced by rubber pocket hydroforming process
Qualified special-shaped sheet metal part, solve through the invention the domestic air mail circle ripple plate parts explosive forming manufacturing cycle it is long,
Unstable product quality, the problems such as dangerous high, working environment is severe, realize the rapidly and efficiently molding of special-shaped sheet metal part.
And work out special-shaped sheet metal part rubber pocket hydroforming process flow, specification technological parameter and Fixture Design main points, and
Form unified standard.The present invention can also be widely used in the manufacture of civilian special-shaped sheet metal part.
Technical scheme of the present invention：Aircraft abnormal shape sheet metal part hydroforming process method, this method implementation steps are as follows：
(1) rubber pocket hydroforming die is placed on hydraulic press workbench；
(2) part blank is placed on rubber pocket hydroforming die, makes the location hole on part blank and rubber cyst fluid
Position of positioning hole on molding die is consistent, is positioned on rubber pocket hydroforming die part blank with mushroom pin；It rises
Hydrodynamic press applies the part blank on rubber pocket hydroforming die the pressure of 8-10MPa, passes through rubber pocket hydro-forming
Mold is preforming to part blank progress, closes hydraulic press, whether there is or not the quality problems of cracking in the type face of inspection part semi-finished product, such as
There is cracking in the type face of fruit part semi-finished product, re-execute step (2) or the corresponding type face to rubber pocket hydroforming die
Repairing type is carried out, until there is no the quality problems of cracking for part semi-finished product, then executes subsequent step；If the type of part semi-finished product
Face then continues to execute subsequent step without cracking；
(3) hydraulic press is started again, and part semi-finished product are applied with the pressure of 20MPa, makes part semi-finished product and rubber cyst fluid
Molding die type face is bonded completely, forms finished part.
Advantages of the present invention：With application of the digitlization in aircraft assembly, the general interchangeability of all kinds of parts is aobvious more
To be important, sheet metal part has accounted for about 2/3 in the composition of aircraft, and can each part have good general interchangeability aobvious
It is even more important.Special-shaped sheet metal part molding difficulty is big, in the past frequently be special popular technique, such as explosive forming technique.Using
The molding part consistency of this method is poor, needs a large amount of manual repairing type, the part manufacturing cycle is long, efficiency is low, interchangeability is poor.It is logical
It crosses the present invention and solves domestic air mail circle abnormal shape sheet metal part manufacturing cycle length, unstable product quality, dangerous high, building ring
The problems such as border is severe realizes the rapidly and efficiently molding of special-shaped sheet metal part.And special-shaped sheet metal part rubber cyst fluid is worked out
Molded technological process, specification technological parameter and Fixture Design main points, and form unified standard.It is of the invention acceptable extensive
In manufacture applied to civilian special-shaped sheet metal part.
Specific implementation mode
The present invention is described in more detail below.
Aircraft abnormal shape sheet metal part hydroforming process method, this method implementation steps are as follows：
(1) rubber pocket hydroforming die is placed on hydraulic press workbench；
(2) part blank is placed on rubber pocket hydroforming die, makes the location hole on part blank and rubber cyst fluid
Position of positioning hole on molding die is consistent, is positioned on rubber pocket hydroforming die part blank with mushroom pin；
(3) hydraulic press is started, applies the pressure of 8-10MPa to the part blank on rubber pocket hydroforming die, passes through
Rubber pocket hydroforming die carries out part blank preforming；
(4) hydraulic press is closed, checks the type face of part semi-finished product whether there is or not the quality problems of cracking, if part semi-finished product
There is cracking in type face, re-execute step (2) or carry out repairing type to the corresponding type face of rubber pocket hydroforming die, until zero
There is no the quality problems of cracking for part semi-finished product, then execute subsequent step；If the type face of part semi-finished product is continued without cracking
Execute subsequent step；
(5) hydraulic press is started again, and part semi-finished product are applied with the pressure of 20MPa, makes part semi-finished product and rubber cyst fluid
Molding die type face is bonded completely, forms finished part；
(6) hydraulic press is closed, is tested to part, inspection is handed over.
