Description
Technical field
The present invention relates to plate Technology of Plastic Processing field, in particular it relates to a kind of flange constraint spinforming apparatus and
Process.
Background technology
Spinning is the continuous plastic forming method of plate single-point, and plate is crushed on core in forming process, with friction
Power effect follows machine tool chief axis to rotate at a high speed, and spinning roller moves in the presence of control system along desired trajectory, passes through accurate position
Control is moved, plate gradually pastes mold forming under spinning roller effect, obtains the revolving body member of integral seamless.Obtained by spinning process
Integrated member has outstanding advantages of formed precision is high, residual stress is small, production cost is low, flexible high relative to welding shaping,
Therefore it is widely used in the manufacture of the formed products such as pressure vessel, pressure vessels for the chemical industry, storepipe, artificial satellite.
With the design requirement of lightweight and the integration of delivery equipment, large scale structure product uses spinning global formation system
Make, be constantly applied in spinning product with stylish high-strength material.Therefore, current rotary press modelling direction maximization, thin-walled
The direction of change is developed.Spinning belongs to big strain, nonlinear deformation problem, and forming process is complicated, to maximization high-strength material rotation
Journey is pressed through, the problem of Instability wrinkling and cracking easily occurs in material, especially big radius-thickness ratio thin-wall member processing.In big radius-thickness ratio
In thin-wall member spinning process, with the feeding of spinning roller, the gradual increase and entirety due to flange hoop pressure stress are relatively low
The rigidity of structure, flange material can start waviness phenomena occur.This ripple is to the shaping later stage, because thin structure of plate slab is firm
Degree deficiency, to a certain extent, plate circumference compression stress is more than critical value, will for hoop pressure stress accumulation caused by plastic deformation
There is flange wrinkle defect, cause follow-up rotary press modelling not continue.In order to prevent occurring flange wrinkle in rotary press modelling
Defect, it is molded usually using multi-pass, but multi-pass shaping brings processing route complex designing, processing is cumbersome, and with
Moulding section material caused by passage increase is drawn the problem of thin serious.In addition to multi-pass moulding process, constrained using flange
Device is also a kind of corrugated effective means of control flange, and particularly with thin-wall member, it is firm can significantly to strengthen flange plot structure
Degree, increase the anti-corrugation ability of material, expand rotary press modelling window, reduce shaping passage.
Found by the retrieval to prior art, in terms of flange constrains spinforming apparatus, patent document
CN104525671A discloses a kind of device and forming method for being molded to the end socket with baffle plate.Core is suitable for reading straight
Footpath 100mm, lower port diameter 20.6mm, height 41mm, slab thickness 1mm, using the general spin forming process of a time with baffle plate, institute
Formed head part radius-thickness ratio 100, bend high ratio 0.4, wall thickness maximum reduction is 10.02% after shaping.The shaped device provides
A kind of single-side flange restriction molding method using ring baffle mode, increase flange plot structure is served to a certain extent
Rigidity, the effect for increasing the anti-corrugation ability of material.But plate only has one side flange constraint to be present when working, in spinning roller active region
Very big gap between side slab and spinning roller still be present, still exist in this side in forming process occur it is corrugated can
Energy.
Also there are some pertinent literatures in the application aspect of Double-face flange constraint technique.Document：Ahmed K I,Gadala M

1.5mm, a time shaping being constrained using Double-face flange, the spinning roller with restraint device applies bilateral constraint to plate flange, and
Fed along core generatrix direction, under the pressure effect of Double-face flange constraint, continuous modification occurs for slab.The shortcomings that this method
It is that restraint device and spinning roller are fixed together, restraining force or constraint gap can not be adjusted, material is thinned seriously, and is only applicable
In the straight edge line molding component of single pass, multi-pass shaping and the regulation in constraint gap can not be realized, it is impossible to suitable for bent female
In line piece rotary press modelling.
