The process processed it is an object of the invention to provide a kind of metal plate forming without surplus and corresponding mould structure designing scheme, it is characterised in that：Product open up without surplus using software (preferably UG or DYNAFORM) and is expected, according still further to the structure size feature of product, carries out 2 shapings, first just shaping, then fasten shaping.The technical solution can solve the problems, such as that the easy cut wound of laser, the processing efficiency of thin-walled hollow support plate are low well, and the process-cycle was reduced to 3 days by 8 days, and efficiency improves 60%, and qualification rate brings up to 100% by 80%.And the processing method is simple, exquisite, has good promotional value.
Description
Technical field
The invention belongs to aero-engine field, especially provides one kind suitable for aero-turbine rear housing product
Thin molded hollow support plate part without surplus processing technology.
Background technology
In aero-turbine rear housing structure, certain hollow support plate product plays support, rectified action, and material is thin plate
(thickness 0.8mm) nickel base superalloy GH536, semi-closed structure, section to be near parabola shaped, two ends be it is spacial special-shaped, its
Structure is as shown in Figure 1.Common processing technology is first to bend, then is fastened, and finally passes through three-dimensional laser again and carries out both ends
Cutting, in laser cutting, product protection is difficult, easy cut wound product, and dimension laser cutting is less efficient.
For product structure feature, the present invention is opened up by using no surplus to expect, realizes no surplus processing, saves three-dimensional laser
Cutting, avoids cut wound, processing efficiency can also greatly improve.
The content of the invention
The process processed it is an object of the invention to provide a kind of metal plate forming without surplus and corresponding mould structure
Designing scheme.The technical solution can solve the problems, such as that the easy cut wound of laser, the processing efficiency of thin-walled hollow support plate are low well, processing
Cycle was reduced to 3 days by 8 days, and efficiency improves 60%, and qualification rate brings up to 100% by 80%.
Technical solution of the present invention is as follows：
A kind of thin molded hollow support plate part without surplus processing technology, it is characterised in that：Using software (preferably UG or
DYNAFORM) product open up without surplus and expected, according still further to the structure size feature of product, carry out 2 shapings, first just shaping,
Shaping is fastened again.
As preferable technical solution：
Product produces offset in forming process in order to prevent, causes product size overproof, carries out no surplus exhibition material
When, increase outwardly directed positioning tab at one respectively in the lateral symmetry middle part of exhibition material figure.The positioning tab
14~16mm of width, 16~20mm of length, head can be rectangle or circle, the circular hole for having a Ф 6mm on each lug.
The just shaping is removed product outside lateral symmetry middle R part type face, and product is pressed in remainder type face
Design drawing finally requires type face to shape, and lateral symmetry middle R part type face is pressed and product design drawing R part type face
Opposite direction shaping, belongs to a kind of unlimited general plane state by product at this time.
Mould is by lower template, cope plate, guide post, guide sleeve, screw, lower die, upper mold, positioning pin and pin used by just shaping
Nail composition, wherein：Cope plate is connected by screw, pin and upper mold, and lower template is connected by screw, pin and lower die, is used
When, upper mold is placed in lower die, lower template is equipped with guide post, and cope plate is equipped with corresponding guide sleeve, is carried out using guide post, guide sleeve
It is accurate to be oriented to；Positioning pin is additionally provided with lower die, the position that its position schemes upper two positioning tabs with exhibition material is corresponding.
The fastening shaping is by carrying out partial plastic forming to the lateral symmetry middle R part of product, reaching product fastening
The purpose of closing, product type face at this time belong to the final claimed condition of design drawing.
No surplus processing technology of the present invention, particularly suitable for the sky in aero-turbine rear housing product
The other products of heart branch plate structure and similar structures.
No surplus processing technology of the present invention is applied in actual production, and is generalized to other type products
In production and processing.Since the application of sheet metal forming technology is extremely extensive, this no surplus processing method is again simple, exquisite, therefore
With good promotional value.

Embodiment
Embodiment 1
A kind of thin molded hollow support plate part is without surplus processing technology, concrete technology step：
(1) carried out accurately opening up material calculating without surplus according to product design figure (see Fig. 1), and in the lateral symmetry centre of product
Position both sides increase an outwardly directed positioning tab respectively (see Fig. 2).Positioning tab width 14mm, length 16mm, head
For rectangle, there is the circular hole of a Ф 6mm on each lug.
(2) technological design is formed according to product design figure, is divided into just shaping and fastens two forming processes.
(3) product shaping procedure technology figure is drawn.
(4) shaping dies (see Fig. 3,4) is designed according to artwork.Mould is equipped with and two positioning tab positions of exhibition material figure
Corresponding positioning pin (in lower die), to ensure that product does not produce offset in forming process；To reduce rebound to product ruler
Very little influence, need to carry out springback compensation processing, to reach being precisely controlled for product size to molding surface size above and below mould；Upper and lower mould
Accurately it is oriented to using guide pillars and bushes.
(5), just shaping, product is removed outside lateral symmetry middle R part type face, remainder type face is set by product
Meter drawing finally requires type face to shape, and lateral symmetry middle R part type face is pressed and product design drawing R part type face phase
