Description
Technical field
The present invention relates to a kind of manufacturing methods of aircraft steering engine ontology, belong to field of machining.
Background technique
Aircraft steering engine ontology is high-strength aluminum alloy precision casting, easily outlet pipe is caused to be cut in process
Object pollution, pollutant are sticked on stainless inside pipe wall, and cleaning is very difficult, have seriously affected the normal production of steering gear body.It is former clear
Washing technique is to be rinsed after per pass manufacturing procedure using high pressure air rifle or giant, is then cleaned with cleaning solution, cleaning effect
It is very unsatisfactory, often there is cutting object blocking and causes scrap of the product.
Summary of the invention
In view of the deficiencies of the prior art, a kind of manufacturing method of aircraft steering engine ontology of the present invention, to solve aircraft rudder
The problem of object pollution, blocking are easily cut in machine ontology process.
In order to solve the above-mentioned technical problem, technical scheme is as follows:
A kind of manufacturing method of aircraft steering engine ontology, includes the following steps:
S1, paste wax is filled into the gas piping of the casting for manufacturing aircraft steering engine ontology, it is cooling；
S2, roughing, finishing then dewaxing treatment are successively carried out to the casting after casting in S1, obtain aircraft steering engine sheet
Body.
In this way, paste wax will be filled in gas piping before casting is further processed, by all gas pipeline
It all blocks, gas piping is first occupied by wax in such cutting process, cutting fluid can be effectively prevent to enter gas piping.To
After whole manufacturing procedures, easily wax can be removed using existing DEWAXING TECHNIQUE clean.
Paste wax has both certain fluidity and keeps the ability of certain shapes, facilitates gassy pipeline.
In the present invention, the roughing and finishing can be used and slightly adds in the conventional processes of aircraft steering engine ontology
The identical technique of work, fine-processing technique.
The manufacturing method of the present invention is applicable to the aircraft steering engine ontology of various models.
Further, before S1, further include the preparation step of paste wax, i.e., paste wax, phase are prepared by mechanical wax stirring machine
Between, the temperature of control paste wax is 51-55 DEG C.
Further, in S1, paste wax is injected by pneumatic wax injector in the gas piping of casting.
Further, the injection pressure of paste wax is 0.3-0.5MPa.
Further, the wax is paraffin.
Further, the casting is made of aluminium alloy.
Further, in S2, dewaxing treatment is carried out by electric heating dewaxing kettle.It can be high by existing electric heating dewaxing kettle
Effect removing wax.
Further, in S2, when dewaxing, casting is placed in electric heating dewaxing kettle, controlled at 130-150 DEG C, is steamed
Steam pressure is 0.35-0.45MPa, and dewax 12-18min.
Compared with prior art, beneficial effects of the present invention are as follows:
1) present invention innovatively proposes the process of a kind of " dredging after first blocking up reprocessing ", before processing, to gas piping
Casting can be effectively prevented the pollution of outlet pipe cutting object, ensure that product quality, improves cost rate, processing is greatly saved
Cost.
2) paste wax is prepared using mechanical wax stirring machine；Paste wax is injected in ontology outlet pipe with pneumatic wax injector, it can
So that wax is full of close in ontology ventilation pipe.
3) it dewaxes in electric heating dewaxing kettle, it can be clean by wax complete liquidation under steam pressure effect.
4) this technology is applied in steering gear body processing, can be effectively prevented and enters cutting fluid in gas piping,
Bulk gas pipeline, such as ventilation pipe are protected in entire mechanical processing process.It is not only effectively guaranteed product quality, is saved
A large amount of cleaning costs solve the technical problem in puzzlement steering gear body processing for many years, create huge economic benefit and
Social benefit.
Specific embodiment
Below with reference to embodiment, the present invention will be described in detail.It should be noted that in the absence of conflict, the present invention
In embodiment and embodiment in feature can be combined with each other.
Embodiment 1
In the present embodiment, the manufacturing method of aircraft steering engine ontology is as follows: preparing paste wax using mechanical wax stirring machine；Use Pneumatic pressure
In the gas piping for the casting that the injection of paste wax is used to manufacture aircraft steering engine ontology by wax machine, injection pressure 0.35Mpa, wax
53 DEG C of liquid temperature；Roughing and fine machining is carried out after casting again；After the completion of whole manufacturing procedures, then by steering engine in electric heating dewaxing kettle
Wax in ontology snorkel is de- clean, and dewaxing temperature is 140 DEG C, steam pressure 0.4MPa, and the dewaxing time is 15min, is flown
Row device steering gear body.
The content that above-described embodiment illustrates should be understood as that these embodiments are only used for being illustrated more clearly that the present invention, without
For limiting the scope of the invention, after the present invention has been read, those skilled in the art are to various equivalent forms of the invention
Modification each fall within the application range as defined in the appended claims.
