Technical field
The present invention relates to the technical field of the attached parts manufacture method of inflator pump, particularly relate to a kind of inflator pump cam manufacture method.
Background technology
As everyone knows, inflator pump is one of inflatable tool; Mainly the running by motor carrys out work.While bleeding, the valve of linker is washed open by the air pressure of atmosphere, and gas enters inflator, and when inflating in tire, valve is closed by the air pressure in inflator again, and gas has just entered in tire; And inflator pump cam is also one of parts indispensable on inflator pump; From China's powder metallurgy production and production system, although be only second to Japan, but from product development ability, technical performance, product quality and manufacture level and competitiveness in the international market thereof, make the country prosperous with world's powder metallurgy---the U.S., Japan, Europe ratio, gap is larger, and main manifestations is:
1. convergentization of product, forms unreasonable.Lack premium quality product.The products such as the high strength of using in automobile engine, damper, gearbox, high density, high-precision powdered metal parts, high accuracy microminiature oiliness bearing, high-quality friction material can't satisfy the demands.
2. properties of product are lower, and reliability is poor.At present, the powder metallurgy iron-base structure parts that China produces, in general, because material powder and auxiliary material source is many, the problems such as quality management, production and technology, product quality is stable not enough, a little less than product development ability, properties of product and reliability and competition radianting capacity wait to strengthen.
Products innovation and self-development ability a little less than, can not meet fast-developing auto manufacturing, electronic technology, office equipment and new ambit and just at developing communication, cutting element, recreation and body-building, biotechnology, family, office automation, material, carry and the supporting demand of other high-technology industries.At present, the powdered metal parts using on the car that a vapour, Second Automobile Works, Shang Qi company produce is mostly with auto parts and components import.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of inflator pump cam manufacture method reducing costs.
Inflator pump cam manufacture method of the present invention, comprises the following steps:
1), produce powder, choose the Ni that weight ratio is 1%-2%, the additive that weight ratio is 0.5%-3%, some plasticizer, surplus is Fe, wherein additive comprises one or more in C, Cu, Si, Mn, P, S or Zn;
2), compressing, by above-mentioned powder, under 400-600MPa pressure, by mould, be that base shape is pressed into required shape;
3), sintering, put copper sheathing and carry out in high temperature meshbeltfurnace or vacuum drying oven, choosing temperature is 1120-1130 degree Celsius, be 45-60 minute access time.

Compared with prior art beneficial effect of the present invention is: by above-mentioned setting, can cut down finished cost.
The specific embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
Inflator pump cam manufacture method of the present invention, comprises the following steps:
1), produce powder, choose the Ni that weight ratio is 1%-2%, the additive that weight ratio is 0.5%-3%, some plasticizer, surplus is Fe, wherein additive comprises one or more in C, Cu, Si, Mn, P, S or Zn;
2), compressing, by above-mentioned powder, under 400-600MPa pressure, by mould, be that base shape is pressed into required shape;
3), sintering, put copper sheathing and carry out in high temperature meshbeltfurnace or vacuum drying oven, choosing temperature is 1120-1130 degree Celsius, be 45-60 minute access time; By above-mentioned setting, can cut down finished cost.
Inflator pump cam manufacture method of the present invention, plasticizer comprises one or more in machine oil, rubber or paraffin.
Inflator pump cam manufacture method of the present invention, plasticizer is the Cu of weight ratio 1.5%.
Inflator pump cam manufacture method of the present invention, the weight ratio of Ni is 1.5%.
The advantage of inflator pump cam manufacture method of the present invention:
1, most refractory metals and compound thereof, pseudo-alloy, porous material can only be manufactured with powder metallurgy process.2, this cam can be pressed into the pressed compact of final size with powder metallurgy process, and does not need or seldom need machining subsequently, therefore can greatly save metal, reduces product cost.The loss of metal only has 1-5%, and while producing with general founding and machine-tooled method, the loss of metal may reach 80%.3, due to powder metallurgical technique molten material not in manufacture of materials process, also be not just afraid of and sneak into the impurity being brought by crucible and deoxidier etc., and sintering generally carries out in vacuum and reducing atmosphere, be not afraid of oxidation, can not give any pollution of material, therefore the material of high-purity likely yet.4, powder metallurgy is produced correctness and the uniformity that cam can guarantee material composition proportioning.5, be suitable for producing same shape and the many high products of product, particularly processing charges of quantity, with powder metallurgic method manufacture, can greatly reduce production costs.The basic working procedure of powder metallurgical technique is: 1, the preparation of material powder.Existing milling method can be divided into two classes substantially: Mechanical Method and physical-chemical process.And Mechanical Method can be divided into: mechanical disintegration and atomization; Physical-chemical process is divided into again: couple corrosion method, reducing process, chemical combination method, reduction-chemical combination method, vapour deposition process, liquid phase deposition and electrolysis.What be wherein most widely used is reducing process, atomization and electrolysis.2, the briquet that powder compacting is required form.The object of moulding is the pressed compact that makes definite shape and size, and makes it have certain density and intensity.The method of moulding is divided into extrusion forming and pressureless compacting substantially.In extrusion forming, applying maximum is compression molding.3, the sintering of briquet.Sintering is the key operation in powder metallurgical technique.Pressed compact after moulding makes it obtain desired final physical mechanical performance by sintering.Sintering is divided into again unary system sintering and heterogeneous sintering.For the solid-phase sintering of unary system and polynary system, sintering temperature is lower than the fusing point of metal used and alloy; For the liquid-phase sintering of polynary system, sintering temperature is generally low than the fusing point of infusibility composition wherein, and higher than the fusing point of low-melting constituent.Except ordinary sinter, also have the special sintering process such as loose sintering, infiltration method, pressure sintering.4, the postorder of product is processed.Processing after sintering, can, according to the difference of product requirement, take various ways.As finishing, immersion oil, machined.In addition, some new technologies, as rolling, forging are also applied to the processing after powdered metallurgical material sintering, obtain comparatively ideal effect in recent years.The Future Development direction of powdered metallurgical material and goods: 1, representational ferrous alloy, by the precise product to large volume, high-quality structure parts development.2, manufacture have even microstructure, processing difficulties and complete fully dense high performance alloys.3, with enhancing densification process, manufacture and generally contain the specific alloy that mixes phase composition.4, manufacture heterogeneous material, amorphous state, crystallite or metastable alloy.5, processing unique with composite elements non-gross morphology or composition.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
