Abstract
The invention discloses a fabrication method of a tail section of a minicar exhaust pipe, and relates to the technical field of car accessory casting. The fabrication method is characterized in that the fabrication method comprises the steps of designing the shape, selecting sand, manufacturing a model and the exhaust pipe, baking, polishing and washing the exhaust pipe, perform fine grinding, and inspecting the product. The method has the advantages of reasonable design, convenient cast and simple operation.
Description
Technical field:
The present invention relates to auto parts machinery casting technology field, be specifically related to a kind of preparation method of minicar blast pipe rear.
Background technology:
Blast pipe is installed between engine exhaust and silencer, makes whole gas extraction system be Flexible spacecraft, thus plays vibration and noise reducing, the convenient effect of installing and extending the exhausting silencer system life-span.Blast pipe is mainly used in Light-duty Vehicle, minicar and passenger vehicle, motorcycle, and exhaust pipe structure covers wire sets outside double-ply bellows, and the structure of two ends straight section overcoat snap ring, for making soundproof effect better, bellows interior can join telescopic joint or net.The main material of blast pipe is stainless steel, and cutting ferrule and adapter material can be stainless steel or aluminum-plated steel.
Blast pipe is a part for engine exhaust system, gas extraction system mainly comprises exhaust manifold, blast pipe and muffler, be generally the three school catalyst converters controlling engine pollutant emission to be also arranged in gas extraction system, blast pipe generally comprises front exhaust pipe and final vacuum pipe.
And general all very simple of the making of the blast pipe of minicar, generally the head section of blast pipe, stage casing, rear are all one, but many minicars is not like this, due to the reason such as vehicle, volume of minicar, blast pipe is often than being easier to damage, the quality of a quality assurance car of blast pipe.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the preparation method that existing technological deficiency provides a kind of minicar blast pipe rear that a kind of method is reasonable, casting is convenient, simple to operate.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A preparation method for minicar blast pipe rear, is characterized in that: comprise the following steps,
Step one, design shape: make different pattern, the model of mouth of different rear and running channel as required;
Step 2, selection sand: select high temperature resistant sand, add C9 Petropols in high temperature resistant sand, then mix bi-material concussion in earthquake equipment;
Step 3, analogue formation: make shaping by the model paraffin designed, be then placed on ventilation, shady and cool local airing 1-2 days;
Step 4, making blast pipe:
I model that will make, rotational model and be coated on model by quartz sand, makes quartz sand be attached to model surface;
The model made in I is put into running channel by II, makes it shaping at the mixture pouring into molten iron and molten steel in running channel;
Step 5, baking blast pipe: the blast pipe after shaping is put into baking box and toasts, the temperature of baking is at 399-421 DEG C, and baking 47-62 minute, makes melted paraffin wax become liquid;
Step 6, polishing blast pipe: the cover plate after baking is put into grinding apparatus, in grinding apparatus, adds the sand chosen in step 3, polished by sand, polishing 14-20 minute;
Step 7, flushing blast pipe: the blast pipe after polishing is taken out, then uses distilled water flushing blast pipe 2-4 minute;
Step 8, meticulous polishing: put into after polishing machine carries out the polishing grinding become more meticulous after the blast pipe after flushing is left standstill 2 minutes and obtain finished product;
Step 9, inspection product: the blast pipe of Chen Pin is tested, qualified packing of product warehouse-in.
Beneficial effect of the present invention is: the intensity of product, toughness height all very, is made by the liquid of different metals, performance very good.The inventive method is reasonable, casting is convenient, simple to operate.
Detailed description of the invention:
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below.
A preparation method for minicar blast pipe rear, is characterized in that: comprise the following steps,
Step one, design shape: make different pattern, the model of mouth of different rear and running channel as required;
Step 2, selection sand: select high temperature resistant sand, add C9 Petropols in high temperature resistant sand, then mix bi-material concussion in earthquake equipment;
Step 3, analogue formation: make shaping by the model paraffin designed, be then placed on ventilation, shady and cool local airing 1-2 days;
Step 4, making blast pipe:
I model that will make, rotational model and be coated on model by quartz sand, makes quartz sand be attached to model surface;
The model made in I is put into running channel by II, makes it shaping at the mixture pouring into molten iron and molten steel in running channel;
Step 5, baking blast pipe: the blast pipe after shaping is put into baking box and toasts, the temperature of baking is at 399-421 DEG C, and baking 47-62 minute, makes melted paraffin wax become liquid;
Step 6, polishing blast pipe: the cover plate after baking is put into grinding apparatus, in grinding apparatus, adds the sand chosen in step 3, polished by sand, polishing 14-20 minute;
Step 7, flushing blast pipe: the blast pipe after polishing is taken out, then uses distilled water flushing blast pipe 2-4 minute;
Step 8, meticulous polishing: put into after polishing machine carries out the polishing grinding become more meticulous after the blast pipe after flushing is left standstill 2 minutes and obtain finished product;
Step 9, inspection product: the blast pipe of Chen Pin is tested, qualified packing of product warehouse-in.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
