Abstract
The present invention discloses a kind of bending machining process of turbo blade, includes the following steps：A, stainless steel plate material, the outer profile blank of prefabricated turbo blade are selected, and ensures the requirement of its overall length；B, the lower die structure for the bending die made is fixedly mounted on lathe, another corresponding flexible mould is upper die structure；C, by turbo blade blank clamping on bending die；D, extruding brake forming process is carried out to blank its other end is manually bent on the basis of blank one end, realize the forming to blank, crooked radian and angle to desired size by bending die；E, it after process finishing, is disassembled from the fixture on bending die, obtains finished product.Using bend processing method of the present invention, solve the problems, such as that bending head is pulled, it can be achieved that one set of die is simultaneously to more than one piece blade Continuous maching, production efficiency is high, and surface quality is good, and processing stablizes, is reliable, is suitable for producing in enormous quantities.
Description
Technical field
The present invention relates to the manufacturing technology fields of turbo blade, in particular to a kind of bending of turbo blade
Processing technology.
Background technology
With the continuous development of science, the various aspects of aerospace field are used for for part as turbo blade,
Such as aerospace flight vehicle parts, missile parts and components and ship parts etc..Turbo blade is a kind of special part, it
Quantity it is more, it is complex-shaped, it is desirable that high, difficulty of processing is big, and is the multiple part of failure, thus its manufacture processing always with
Being the key link of each manufacturing and processing enterprise.The existing common process of turbo blade bending machining is to utilize to have guide post typo die
Tool is bent, and is processed using the mold, in the case where processing quantity is big, leaf head easy tos produce larger scratch
And pull, especially an angle of 90 degrees out often walks principal-employment, and the part of processing is caused not meet technological requirement, anti-due to needing to carry out
Multiple repairing mold molding part, worse and worse, product qualification rate is increasingly for the part quality produced eventually by mold
It is low, qualified product can not be delivered at all to user.Meanwhile using the shortcomings that this processing method be mould production cost compared with
Height, and mold service life is short, the unqualified ratio of product size is very high.It can be seen that using existing processing technology
The requirement that turbo blade part product produces processing in enormous quantities cannot be met.
Invention content
The technical problem to be solved by the present invention is to be directed to background technology, a kind of the curved of turbo blade is proposed
Bent processing technology, by existing guide post die expand port mechanical process technique be changed to by mold to turbo blade into
Row squeezes bending and molding method, to solve to easy to produce larger scratch for leaf head in conventional method and pull situation,
And there is the problem of principal-employment in its an angle of 90 degrees, and the turbine blade surface processed using bending and molding method is high-quality, efficient, table
Face consistency is good, and processing stablizes, is reliable.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of bending machining work of turbo blade
Process, it includes the following steps：
A, prefabricated blank：Stainless steel plate material is selected, turbo blade is precast in advance in machine tool or numerical control machining center
Outer profile blank, and ensure its overall length requirement；
B, installation mold：The lower die structure for the bending die made is fixedly mounted on lathe, another pair is answered
Flexible mould be upper die structure；
C, blank clamping：By prefabricated turbo blade blank clamping on bending die；
D, it shapes：Blank is carried out by bending die to squeeze brake forming process, using blank one end as base
Its other end is manually bent in standard, realizes the forming to blank, crooked radian and angle to desired size；
E, part is dismantled：After process finishing, part is disassembled from the fixture on bending die, is obtained into
Product.
Further, the bending machining process of a kind of turbo blade, wherein extruding bending operation institute
The power needed is air pressure or hydraulic pressure, and required pressure and rate travel can continuously adjust.
It is compared with prior art, beneficial using a kind of bending machining process of turbo blade of the present invention
Effect is：The processing technology of bending forming is used by bending die, process is simple, the positioning of mold
Adjustable, product size is preferable, and presentation quality is also higher, and there is no bending heads to pull situation, and one set of die easy to implement
Simultaneously to more than one piece pin key Continuous maching, prouctiveness, the low easy making of mould production cost and repair are improved, is demonstrate,proved through production practices
It is bright reliable easy.This bending method turbine blades are efficient, and surface quality is good, and consistency is good, and processing stablizes, is reliable.
Production cost has greatly been saved, the Mold Making cost period is reduced, has been suitable for producing in enormous quantities.This process has been applied
In production, product effect is fine.

Clearly and completely describe：
As shown in Figures 1 to 4, the bending machining process of a kind of turbo blade of the invention, it includes the following steps：
A, prefabricated blank：Stainless steel plate material is selected, turbo blade is precast in advance in machine tool or numerical control machining center
Outer profile blank, and ensure its overall length requirement；
B, installation mold：The lower die structure for the bending die made is fixedly mounted on lathe, another pair is answered
Flexible mould be upper die structure；
C, blank clamping：By prefabricated turbo blade blank clamping on bending die；
D, it shapes：Blank is carried out by bending die to squeeze brake forming process, using blank one end as base
Its other end is manually bent in standard, realizes the forming to blank, crooked radian and angle to desired size；
E, part is dismantled：After process finishing, part is disassembled from the fixture on bending die, is obtained into
