Description
Technical field
The invention belongs to solid propellant rocket heat insulation layer manufacturing technology field is and in particular to a kind of insulating structure is uniform
The control method of property.
Background technology
During heat insulation layer overall vacuum paster, heat insulation layer raw cook is wrapped in outside rubber pneumatic bag to insert housing corresponding
Position, realizes the stickup of heat insulation layer raw cook and housing, the gas replenishment process of rubber pneumatic bag is rubber in rubber pneumatic bag gas replenishment process
Air bag is heaved to utricule design shape by flat form, and heat insulation layer raw cook is applied with the process of stress.In this course, rubber
Heaving of each position of glue air bag is not uniformity, and the speed of heaving of the valve position of rubber pneumatic bag is more than remaining position,
Therefore there is the possibility being placed in the displacement of rubber pneumatic bag upper thermal barrier layer raw cook, thus wrinkle and flange occur.Rubber pneumatic bag fills
Man Hou, before applying stress, the state of heat insulation layer raw cook is its design point, system for avoiding heat insulation layer raw cook to paste
Property fold defect, reserve process allowance, heat insulation layer raw cook external diameter now is less than housing inner diameter, the external diameter of rubber pneumatic bag simultaneously
Minimum diameter less than heat insulation layer raw cook.Rubber pneumatic bag applies in stress path, and rubber pneumatic bag continues to expand, and drives adiabatic simultaneously
The ring of layer raw cook extends, and the thickness of heat insulation layer raw cook also synchronously reduces, and due to the effect of gravity, each position of heat insulation layer raw cook is thick
The decreasing value of degree is inconsistent, and upper numerical is more than bottom, and bottom is substantially zeroed, and top is maximum, defines local reduction
Phenomenon.If uniformly thinning, heat insulation layer raw cook thickness can be taken to reserve the means of surplus, but local reduction is then invalid.Exhausted
In thermosphere production process, problem generally existing in uneven thickness, causes adiabatic layer weight to exceed design objective requirement after reprocessing
Quality problems.
Content of the invention
The present invention provides a kind of control method of insulating structure uniformity, and to reach, insulating structure is complete, thickness is equal
Even, so that it is guaranteed that the purpose of product quality.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of control of insulating structure uniformity
Method processed, concretely comprises the following steps：
1）Preparation process：According to electromotor insulating structure feature, design and the corresponding rubber pneumatic bag of manufacture；Calculate, survey
Examination vacuum is that rubber pneumatic bag heaves required air inlet total amount V completely in the state of -0.096MPa1And rubber pneumatic bag is substantially swollen
Swollen required air inlet total amount V2；Described heave completely refer to rubber pneumatic bag inflation after, be in and heave but not inflated shape
State；After basic expansion refers to rubber pneumatic bag inflation, it is in and touches heat insulation layer raw cook but to heat insulation layer raw cook pressure
State；
2）Evacuation step：Motor body with heat insulation layer raw cook and rubber pneumatic bag is pushed vacuum chamber, evacuation, vacuum
Spend for -0.096MPa；
3）Fill row's step：Continue pressurize in vacuum chamber, inflate into rubber pneumatic bag, institute's inflatable body volume is V1/ 2, then
Stop inflation, start aerofluxuss, institute's exhaust volume is V1/ 4, continue to be inflated to V1/ 2, aerofluxuss again, institute's exhaust volume is V1/ 4,
Continuous charge afterwards, until rubber pneumatic bag is heaved completely；
4）Aeration step：Continue pressurize in vacuum chamber, slowly inflate into rubber pneumatic bag, until gas is total in rubber pneumatic bag
Amount reaches V2, stop inflation；
5）Spin step：Motor body is driven at the uniform velocity to rotate a circle using servo vacuum motor；
The structural homogeneity of the heat insulation layer being processed by above-mentioned steps is improved.
Described 2）In evacuation step, the relative position relation of heat insulation layer raw cook, rubber pneumatic bag and motor body is thermal insulation
Layer raw cook is located in engine shell body, and rubber pneumatic bag is located in heat insulation layer raw cook.
Described 2）Before evacuation step, smear adhesive inside motor body.
Described 2）Before evacuation step, inside motor body, smear adhesive, and daub is also applied on heat insulation layer raw cook
Stick.
Described 3）Fill in row's step, the speed controlling of aerofluxuss and inflation is in 50 ~ 60L/min.
Described 4）In aeration step, aeration speed controls in 10 ~ 15L/min.
Described 5）In spin step, rotary speed controls in 10 ~ 15 turns/min.
The inflation of rubber pneumatic bag and the conversion of exhaust process, the speed of controller inflation and aerofluxuss is it can be ensured that rubber gas
The each position of capsule heave uniformity, it is to avoid being placed in rubber pneumatic bag top raw cook is shifted over.In rubber pneumatic bag unaerated
To basic expansion, because the gap between motor body and heat insulation layer raw cook is excessive, carry out rotation adjustment and certainly will drive absolutely
The movement of thermosphere raw cook and rubber pneumatic bag and upset, lead to heat insulation layer raw cook fold and distortion, and have been inflated in rubber pneumatic bag
After full expansion, heat insulation layer raw cook is had occurred and that with motor body and contacts, and the purpose carrying out rotating adjustment cannot be realized.Cause
This, after rubber pneumatic bag expands substantially, carry out rotation adjustment, can solve the thickness effect to heat insulation layer raw cook for the gravity, to reach
To insulating structure is complete, purpose in uniform thickness.The present invention has been successfully applied to several type products, the type face matter of heat insulation layer
Amount significantly improves, and solves heat insulation layer quality problems in uneven thickness, and product has passed through rocket engine ground test examination.
