Description
Technical field
The present invention relates to a kind of metal material for friction-type Positioning hinge.
Background technology
Each product is due to the difference of purposes, and the quality requirements of its processing technology and raw material is also different.In general the difference of stainless steel products, it requires that raw thickness tolerance is also different, resemble two dishwares and thermos cup etc., thickness deviation General Requirements is higher, for-3 ~ 5%, and a dishware thickness deviation General Requirements-5%, steel pipe generic request-10%, hotel refrigerator material thickness deviation requires as-8%, dealer to the requirement of thickness deviation generally between-4% ~ 6%.The difference that product sells inside and outside simultaneously also can cause client to the difference of raw thickness tolerance.The thickness deviation of general exported product client requires higher, and domestic enterprise requires relatively low (mostly considering for cost aspect) to thickness deviation, and portions of client even requires-15%.
1. DDQ(deep drawing quality) material: refer to the material for deep-draw (punching) purposes, namely everybody said soft material, this
materialmain feature be higher (≤53% of elongation per unit length), lower (≤170% of hardness), internal grain grade is between 7.0 ~ 8.0, and deep drawability is splendid.The enterprise of many production vacuum flask, pot class, the processing of its product is general all higher than (BLANKING SIZE/ goods diameter), and their processing is than reaching 3.0,1.96,2.13,1.98 respectively.SUS304DDQ material is exactly mainly the product requiring higher processing ratio for these, and processing generally all needs just can complete through the stretching of a few passage than the product more than 2.0 certainly.If raw material extension aspect does not reach, when processing shell, product very easily cracks, draws the phenomenon of wearing, and affects product qualified rate, certainly also just increases the cost of producer;
2. general material: be mainly used in the material except DDQ purposes, the feature of this material is relatively low (≤45% of elongation per unit length), and the relatively high (≤180HB of hardness), internal grain degree grade is between 8.0 ~ 9.0, compare with DDQ material, its deep drawability is relatively slightly poor, and it is mainly used in not needing to stretch drawing just getable goods, resembles the spoon of a dishware, spoon, fork, electrical appliance, steel pipe purposes etc.But it has an advantage compared with DDQ material, be exactly that BQ is relatively better, this is mainly due to cause that its hardness is slightly high.

A kind of metal material for friction-type Positioning hinge of the present invention, has excellent electric conductivity, thermal conductivity, ductility and corrosion proof advantage.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Wherein, the described metal material for friction-type Positioning hinge comprises the zinc-iron alloy of the superiors, copper-iron alloy and the undermost stainless steel in intermediate layer combine, described zinc-iron alloy comprises iron, zinc, aluminium, copper, magnesium, cadmium, plumbous, titanium, described zinc-iron alloy occupies the 44%-56% of the overall component of metal material of friction-type Positioning hinge, described copper-iron alloy occupies the 23%-25% of the overall component of metal material of friction-type Positioning hinge, described stainless steel occupies the 20%-22% of the overall component of metal material of friction-type Positioning hinge, described stainless steel comprises molybdenum, vanadium, copper, manganese, nitrogen.
Further illustrate, described zinc-iron alloy occupies 56% of the overall component of metal material of friction-type Positioning hinge, described copper-iron alloy occupies 23% of the overall component of metal material of friction-type Positioning hinge, and described stainless steel occupies 21% of the overall component of metal material of friction-type Positioning hinge.
Further illustrate, zinc-iron alloy also claims alloying zinc-plated.Alloying process is heated to 550-560 DEG C galvanized steel by alloying furnace at 5-10 second, pure zinc layer is all converted into iron-kirsite.Its weldability, be coated with performance, heat resistance, corrosion resistance and be all better than common galvanized sheet.. be applicable to alkaline low iron zinc-iron alloy technique,
coatingiron-holder 0.3 ~ 0.8%; Coating
crystallizationcareful, brightness is bright in vain; The easy passivation of alloy layer, the alloy layer after passivation, its corrosion resistance is more than three times of zinc layers passivation; Bath stability, easily safeguards, can rack plating or barrel plating (containing transfer matic); Cost compare is low, and existing equipment can be utilized to be formed by former zincate galvanizing liquid turn trough.
Further illustrate, adding rare earth on a small quantity can refinement copper-iron alloy, and the melt temperature of copper and iron is more or less the same, and all at about 1200 degree, they completely can be compatible again.There is excellent electric conductivity, thermal conductivity, ductility and corrosion resistance, combine the advantage of copper and iron.
Stainless
corrosion resistancewith containing
carbonthe increase of amount and reducing, therefore, most of stainless phosphorus content is all lower, is maximumly no more than 1.2%, the ω c(phosphorus content of some steel) even lower than 0.03%(as 00Cr12).Main alloy element in stainless steel is Cr(chromium), only have when Cr content reaches certain value, steel have corrosion resistance.Therefore, the general Cr(chromium of stainless steel) content is at least 10.5%.Also containing elements such as Ni, Ti, Mn, N, Nb, Mo, Si, Cu in stainless steel." stainless steel " one word be not only refer to a kind of stainless steel merely, but represent kind more than 100 industrial stainless steel, often kind that the develops stainless steel capital has good performance in its specific application.First successful key is to understand fully purposes, and then determines correct steel grade.The steel grade relevant with architectural construction application only has six kinds usually.They all contain the chromium of 17 ~ 22%, and good steel grade is also containing nickel.Add molybdenum and can improve atmospheric corrosiveness further, the particularly corrosion of the air of resistance to chloride.Stainless steel is often divided into by structural state:
martensite steel,
ferritic steel,
austenitic steel, austenite-ferrite (two-phase) stainless steel and precipitation-hardening stainless steel etc.In addition, can be divided into by composition: straight-chromiun stainless steel, chromium nickel stainless steel and chromic manganese nitrogen stainless steel etc.The invention provides a kind of metal material for friction-type Positioning hinge, there is excellent electric conductivity, thermal conductivity, ductility and corrosion proof advantage.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
