The present invention provides a non-chlorine type lubricant in which a sulfur type extreme pressure additive, an organic zinc compound, a calcium type additive, and an ester compound are blended with a base oil for the lubricant, and having a kinetic viscosity from 5 to 50 mm<2>/s at 40 DEG C.

Description

The metallic substance press working with lubricator with the working method of using it
Technical field
The present invention relates to be used for the non-chlorine type lubricant of metallic substance press working.Particularly, it relates to and is suitable for being used as parts such as purolator box, the lubricant of the press working of the metallic substance of handling in the after-applied coating of press working.In addition, it relates to the metallic substance pressure processing method that uses this lubricant.
Background technology
When the press working of metallic substance, lubricant generally puts between cutter and the metallic substance.This is to increase the Mould Machining life-span deterioration that causes in the processing by the generation of breaking of causing of lack of lubrication or interlock or by friction.In the shearing as a class press working, metallic substance is made its punching press by using mould and stamping machine.Therefore, in shearing technology such as smart stamping-out (FB processing), between cutter and metallic substance, produce than other compacting or the bigger stress of machining.Therefore, the lubricant that is used to shear is required high bite-resistant performance or lubricity.
Used the lubricant that adds the high chlorine type additive of oilness.Yet, when using chlorine type lubricant, can take place during the chlorine type additive component in the lubricant is being processed or decompose in time after the processing to cause the problem that metallic substance or cutter get rusty.In addition, for chlorine type lubricant, during calcining, may cause the generation of objectionable impurities or burn into infringement etc. and the generation problem to calcining furnace by causing.
Consider above-mentionedly, JP-A No.2002-155293 and 8-20790 disclose the lubricant as non-chlorine type lubricant.Yet, consider the bite-resistant that is used for the metallic substance press working or the oilness of lubricant, this lubricant is used for machining, still there are the problems referred to above.
By making the metallic substance of with lubricator making because the cause of lubricant requires follow-up degreasing and cleaning.For example, depend on parts as the box that is used for the motor vehicle purolator and further apply plating or application step.In this case, unless in cleaning with the complete degreasing of lubricant or cleaning (hereafter is cleaning), the oil residues composition repels coating material and causes plating spot or coating spot.Therefore, consider sanitary characteristics, the lubricant kinetic viscosity is preferably low as far as possible.Sanitary characteristics means the lubricant composition and is easy to wash from metal material surface.Under the lower situation of lubricant kinetic viscosity, lubricant can easily clean, and it can for example only successfully clean with basic ion water cleaning.Yet when considering oilness, the preferred emollient kinetic viscosity is high as far as possible.Under lubricant kinetic viscosity condition with higher, because depositing to the amount of metal material surface, lubricant increases, favourable seizure resistance or oilness can be provided.So, exist non-chlorine type, environmental friendliness, oilness is good and subsequent step is had the demand of the lubricant that is used for the metallic substance press working of low disadvantageous effect as cleaning or coating.
Summary of the invention
Lubricant according to the present invention has non-chlorine type to be formed, (a) sulphur type extreme pressure agent wherein, (b) organic zinc compound, (c) calcium type additive and (d) ester type compound and lubricant base oil blend.It can provide, and processing does not have disadvantageous effect and environmentally friendly in a life-span to cutter, and the lubricant of excellent lubrication and seizure resistance is provided.Especially, even under the low relatively situation of lubricant kinetic viscosity, can provide satisfied oilness and seizure resistance.In addition, will be controlled at 5-50mm 40 ℃ kinetic viscosity 2/ s (cSt).Under the situation that will be controlled at 40 ℃ kinetic viscosity in the above-mentioned scope, because lubricant has suitable flowability, this lubricant can easily clean after processing, and also is fine with basic ion water cleaning, also guarantees good lubricated and seizure resistance simultaneously in shearing.Therefore, can effectively suppress disadvantageous effect to subsequent step such as plating step or application step.
(a) sulphur content can be 0.5-10 weight %, total amount based on lubricant, (b) zinc content can be 0.05-1.0 weight %, total amount based on lubricant, (c) calcium contents can be 0.1-2.0 weight %, based on the total amount of lubricant, and (d) ester content can be 0.1-2.0 weight %, based on the total amount of lubricant.
In addition, the present invention can provide the pressure processing method of metallic substance, and it is included in and carries out processing steps when applying lubricant between metallic substance and the cutter.As this metallic substance, use Rustproof Steel Plate (preferred electrolytic zinc coated steel sheet).Apply shearing when between cutter and metallic substance, applying lubricant.After the shearing, with the basic ion water clean metal material that is heated to 60 ℃-80 ℃.Then, metallic substance being applied coating handles.At metallic substance is under the situation of Rustproof Steel Plate, does not require to guarantee high rust-preventing characteristic in lubricant, thereby also avoids the increase of cost and lubricant viscosity to improve.Basic ion water is being heated under 60 ℃-80 ℃ the situation, the sanitary characteristics of lubricant is improved.Under the situation of available bases ionized water cleaning, can reduce the sanitising agent cost and make the cleaning facility.
