The present invention provides a kind of preparation processes of beryllium-bronze piston ring for improving the elastic service life, which mainly passes through die casting machine die cast, and the piston ring is mixed by beryllium-bronze, steel, silica, inorganic high-temp glue and manganese dioxide.The present invention has rational design, easy to process, can not only improve the structural strength of piston ring entirety, meanwhile, it also can satisfy the purpose for improving the piston ring body elastic service life.
Description
Technical field
The invention mainly relates to the technical fields of piston ring processing, and in particular to a kind of beryllium-bronze for improving the elastic service life is living
The preparation process of plug ring.
Background technique
Piston ring is the becket for being embedded in inside piston groove, and piston ring is divided into two kinds：Compress ring and machine oil ring, pressure
Contracting ring can be used to the burning mixture in sealing combustion room；Machine oil ring is then used to strike off machine oil extra on cylinder, piston ring
It is a kind of with the larger metallic elastic ring for expanding outwardly deformation, it is mounted in its corresponding annular groove of section, back and forth
With the piston ring of rotary motion, by the pressure difference of gas or liquid, at one of ring periphery and cylinder and ring and annular groove
Sealing is formed between side.
During piston ring is used for a long time, piston ring body flexibility decrease can all occur, seriously will appear complete mistake
The phenomenon of elasticity is gone, and flexibility decrease will lead to engine poor sealing, collaborate, burn oil, compression ratio (cylinder drops) influences
Engine power output.
Summary of the invention
It is above-mentioned to solve invention broadly provides a kind of preparation process of beryllium-bronze piston ring for improving the elastic service life
It is proposed in background technique, since piston ring follows the string is exported to engine power the technical issues of impacting.
The present invention solve the technical solution that uses of above-mentioned technical problem for：Main process of the invention is as follows：
Step 1：Weighing apparatus is first passed through, suitable steel and beryllium-bronze is weighed, adds it in high temperature melting furnace, pass through
High temperature action is smelted into molten condition；
Step 2：During steel-smelting and beryllium-bronze, by weighing apparatus, suitable silica and titanium dioxide are weighed
Manganese is added thereto, and carries out melting；
Step 3：After complete melting, molten liquid is circulated into the compression mod of die casting machine, molten liquid is being circulated into pressure
After in casting machine, inorganic high-temp glue is being poured into mold；
Step 4：After die casting machine die cast, piston ring ingredient after molding is transported in cooling chamber carry out it is cold
But；
Step 5：After piston ring embryo material is cooling, is being polished using sander the piston ring embryo material, polished
Processing both obtains finished product.
Steel is the general designation of the iron-carbon alloy to phosphorus content mass percent between 0.02% to 2.11%.The change of steel
Studying point can be with great changes have taken place, and the steel containing only carbon is known as carbon steel (carbon steel) or ordinary steel；In actual production, steel is past
Contain different alloying elements toward difference depending on the application, such as：Manganese, nickel, vanadium etc..Application and research history of the mankind to steel
It is quite long, but until the Bessemerizing invention of 19th century, steel produce all be a high efficiency at low cost work.
Nowadays, steel becomes one of most commonly used material in the world with its cheap price, reliable performance, is construction industry, manufacturing industry
With ingredient indispensable in people's daily life.It may be said that steel is the material base of modern society.
Beryllium-bronze, using beryllium as a kind of tin-free bronze of major alloy constituent element.Containing 1.7~2.5% berylliums and a small amount of nickel,
The elements such as chromium, titanium, after quenching ageing treatment, strength degree is up to 1250~1500MPa, close to the water of moderate strength steel
It is flat.Plasticity is fine under as-quenched, can be processed into various semi-finished product.Beryllium-bronze has very high hardness, elastic limit, tired
The labor limit and wearability also have good corrosion resistance, thermal conductivity and electric conductivity, spark are not generated when being hit, is widely used as
Important elastic element, wear part and explosion-proof instrument etc..The common trade mark has QBe2, QBe2.5, QBe1.7, QBe1.9 etc..
Silica, the technical terms of chemistry, pure silica is colourless, is solid, chemical formula SiO under room temperature2, do not dissolve in
Water.Insoluble in acid, but it is dissolved in hydrofluoric acid and hot concentrated phosphoric acid, can and melt bases and work.There are crystallization dioxies in nature
SiClx and two kinds of amorphous silica.Silica have many uses it is general, be mainly used for glass processed, waterglass, pottery, enamel,
Refractory material, aerogel blanket, ferrosilicon, molding sand, elemental silicon, cement etc., in ancient times, silica also are used to make the glaze paint of porcelain
And carcass.General stone is mainly made of silica, calcium carbonate.
Manganese dioxide (nature presence in the form of pyrolusite).Physical behavior：Black amorphous powder or black iris
Body.Dissolubility：It is insoluble in water, weak acid, weak base, nitric acid, cold sulfuric acid, concentrated hydrochloric acid is dissolved under heating state and generates chlorine.
Inorganic high-temp glue is a kind of critically important fine chemical product, and bonding force is strong, fireproof high-temperature resistant, and anti-impact force is good,
Nontoxic to volatilize without any substance, application has been deep into the every field of national economy.
During processing, using steel as base-material, it is ensured that the structural strength of piston ring body, meanwhile, pass through dioxy
The effect of SiClx, manganese dioxide is, it can be achieved that improve the purpose of piston ring body structural strength；
Further, on existing market, do not occurred being added to the constituent of piston ring using beryllium-bronze as auxiliary material
In, and beryllium-bronze not only has good thermally conductive, corrosion resistance, improves the overall efficacy of piston ring, meanwhile, beryllium-bronze is one
Kind of the very superior metal material of elastic effect, is added beryllium-bronze in piston ring ingredient, can not only optimization piston ring entirety
Structural strength, meanwhile, it is capable to enhance the integrally-built elasticity of piston ring；It further, can by the effect of inorganic high-temp glue
The elastic service life of overall improvement piston ring, meanwhile, by the effect of inorganic high-temp glue, molten can be increased in molten condition
Under state, intermolecular cohesiveness, and then increase the inner structural strength of piston ring.
Compared with prior art, beneficial effects of the present invention are：The present invention has rational design, easy to process, can not only mention
The structural strength of high piston ring entirety, meanwhile, it also can satisfy the purpose for improving the piston ring body elastic service life.
