Abstract
A manufacturing method for a throttle valve comprises the following steps that a copper block with the sulfur content of 0.1 is selected and heated to 1,000-2,300 DEG C, the copper block is placed into a converter to be smelted, air evaporation is carried out, and the carbon content is reduced to be lower than 0.1%. High-purity refined copper is obtained through cooling. A valve element of the throttle valve is designed through a computer, the refined copper is turned through a turning tool in a machining center, and the precise valve element is obtained. Materials needed for iron casting are prepared, the materials are poured into a die and pressurized to 100-260 Mpa, and pressure is maintained for 1-2 h. Die stripping is carried out, and a die stripping machine used during die striping is a full-automatic die stripping machine. Burrs are removed after die stripping, oxygen reduction treatment is carried out on a fracture, and the valve element is placed in a cast shell. According to the throttle valve, waste of gas which cannot be burnt can be reduced, gas sources are saved, and the purposes of environment protecting, emission reducing and air pollutant reducing are achieved.
Description
Technical field
The invention belongs to mechanical field, particularly a kind of preparation method of air throttle.
Background technology
Inside present city, automobile gets more and more, and the pollution of tail gas is also day by day serious, and how present economizes on resources, and decreasing pollution just becomes the problem that is concerned whether sustainable development.
Summary of the invention
The object of this invention is to provide a kind of preparation method of air throttle, this air throttle can reduce the waste of aphlogistic gas, saves the object that origin reaches environmental emission reduction and reduces the pollutant in air.
The technical scheme adopted is:
A preparation method for air throttle, comprises the following steps:
First choose the copper billet of sulfur content 0.1, heating 1000-2300 degree Celsius, copper billet fusing is put in the middle of converter and melts, then steam through gas, reduce phosphorus content and reach lower than 0.1%.
Then cooling obtains the higher smart copper of purity.
Use computer design air throttle spool, then use machining center to carry out lathe tool Vehicle Processing to smart copper, obtain accurate spool.
Then prepare the material that cast iron needs, material is poured into pressurize in the middle of mould 100-260Mpa, then pressurize 1-2 hour.Then the demoulding, the ingot stripper used when the demoulding is full-automatic ingot stripper.
Releasing agent is clear water.
The demoulding removes burr later, then goes out to carry out oxygen reduction process to fracture, then spool is loaded in the middle of the housing cast.
Its advantage is:
This air throttle can reduce the waste of aphlogistic gas, saves the object that origin reaches environmental emission reduction and reduces the pollutant in air.
