Abstract
The invention discloses a kind of Agricultural Machinery Equipment traveling wheel lost foam casting process, specifically includes the following steps: S1, white mould raw material to be put into the inside of foaming machine first, then running equipment makes foaming machine work, since surface and internal moisture are excessive after the first one-step forming of Bai Mo foaming completion, so white mould is dried, the white mould of evaporative pattern is placed on to the top of baker, baker dries the moisture inside the white mould of evaporative pattern, and the present invention relates to Agricultural Machinery Equipment traveling wheel production fields.The Agricultural Machinery Equipment traveling wheel lost foam casting process, by the way that the white mould handled well is carried out split according to the required size for carrying out casting mold article, use lost foam casting traveling wheel instead, without using sand core, reduce casting cost, the labor intensity of worker is significantly alleviated, conducive to the use of people, this solves the problems, such as that current existing Agricultural Machinery Equipment traveling wheel lost foam casting process is high using sand core production traveling wheel labor intensity of workers.
Description
Technical field
The present invention relates to Agricultural Machinery Equipment traveling wheel production field, specially a kind of Agricultural Machinery Equipment traveling wheel lost foam casting work
Skill.
Background technique
Lost foam casting is the cavityless casting that foam mould uses bindless dry sand combination vacuum pumping technology, and the country is main
The call wanted has " dry sand cavityless casting ", " vacuum full mold casting ", abbreviation EPC casting；Lost foam casting is at present in the world most
One of advanced casting technique, primary " revolution " being known as in casting history, is referred to as 21 century Green foundry both at home and abroad, disappears
Die cast (also known as cavityless casting) be foam mould use bindless dry sand combination vacuum pumping technology cavityless casting, be by
Bubbles model bonding similar with casting dimension shape is combined into model cluster, after brushing fireproof coating and drying, is embedded in drystone English
Vibration molding in sand, is poured under negative pressure, and model is made to gasify, and liquid metals occupies modal position, forms casting after solidification is cooling
Novel casting method, compared with conventional casting technologies, lost foam casting has following features: casting quality is good, at low cost；Material
Unlimited, size is all suitable；Dimensional accuracy is high, any surface finish, reduces cleaning, and saving machine adds；Internal flaw greatly reduces, and tissue causes
It is close；Extensive, mass production can be achieved, the raw environmental protection of automatic assembly line can substantially improve operating environment, reduce labour by force
Degree reduces energy consumption.
Traveling wheel original production process is clay sand molding process, needs two plum blossom form sand cores, complex process is at high cost
Large labor intensity.It is not suitable for sand core in order to reduce cost, reduces labor intensity of workers, lost foam process is used in rear experiment instead.But
There is carbon slag and hard spot by surface when processing in the product of trial-production.There are internal flaws by production line detection for product, and grade is not
It meets the requirements of the customers.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of Agricultural Machinery Equipment traveling wheel lost foam casting process, solve
The problem of Agricultural Machinery Equipment traveling wheel lost foam casting process.
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs: a kind of Agricultural Machinery Equipment traveling wheel disappearance
Die cast technique, specifically includes the following steps:
S1, the inside that white mould raw material is put into foaming machine first, then running equipment makes foaming machine work, Bai Mofa
It finishes into after first one-step forming since surface and internal moisture are excessive, so white mould is dried, the white mould of evaporative pattern is placed on
The top of baker, baker dry the moisture inside the white mould of evaporative pattern；
Do not have moisture inside white mould after S2, drying, but surface is but not flat and smooth enough, it in this way can be to after evaporative pattern
Continuous use impacts, and is processed by shot blasting by surface of the sanding and polishing device to the white mould of evaporative pattern, and fills up bumps not
The surface of the white mould of evaporative pattern is become smooth by flat region；
S3, the size that the white mould handled well is carried out to casting mold article as required carry out split, in strict accordance with technological design
Required size and shape carries out bonding assembly, is bonded between the white mould of muti-piece evaporative pattern by glue special；
S4, etc. glue between the white mould of evaporative pattern of completion to be bonded parch after the surface of the white mould of evaporative pattern is brushed
Special coating, and guarantee that paint thickness is consistent everywhere on surface, surface is uniform, and it is white to evaporative pattern after brushing to dry, make
The coating on its surface quickly solidifies, wait it is to be solidified after the white mould of evaporative pattern is subjected to vanning transport；
S5, it is placed in position after it will package the white mould of evaporative pattern that transport comes and take out, then required for melting
The white mould of evaporative pattern is then placed on the appropriate location in casting mold by the material of casting, then by the melting material liquid of thawing
The surface of the inside i.e. the white mould of evaporative pattern of pouring into casting mold carries out casting, by it from pouring after waiting object to be cast cooling
It is taken out in injection molding tool, then clears up the white mould residue of evaporative pattern and magazine on surface, then it is carried out by sanding and polishing machine
Sanding and polishing, until object surface is smooth；
S6, object that polishing terminates is taken out, then it is detected by instrument, it is ensured that without A Jing and massless or
Person's other problems, then clean it, it is ensured that object clean degree is beaten after the drying by dryer later
Packet, can transport later to the region of needs carry out using.
Preferably, the material of the foaming white mould of evaporative pattern must be added production in strict accordance with standard in the S1, can not
It is arbitrarily added material or reduces material, and the temperature dried can not be excessively high, also unavailable open fire carries out direct baking,
It needs to control certain temperature and vacates a distance.
Preferably, in the S2 final process white mould must length, width and height be in same horizontal line, and can not mistake
The material for measuring white mould surface of skimming, otherwise can excess waste.
Preferably, specified glue and work step must be used when bonding in the S3 and it is necessary to wanted casting
Article size is completely the same.
Preferably, it keeps thickness uniform when the S4 dialogue mould is brushed, will not influence the subsequent use of Bai Mo in this way.
Preferably, the S5 to pour the size that immutable object surface is needed to pay attention to when the object being poured in is polished and
Otherwise length, width and height can be such that object is not available, cause irremediable loss.
Preferably, when the S6 detects object, the peak of detection object is not needed, it is only necessary to reach standard value
Up and down:
(3) beneficial effect
The present invention provides a kind of Agricultural Machinery Equipment traveling wheel lost foam casting process.Having compared with prior art following has
Beneficial effect:
