Cold-heading processing is the forging method for being shaped to metal bar material jumping-up (being often gathering stock) using mould at normal temperatures. Cold-heading is another form of upsetting.More metal mold becomes theoretical, applies certain pressure to metal stock at normal temperatures, It is allowed to be deformed in die cavity.By the shape and size shaping of regulation.Cold heading technique is widely used in middle finding and various The standard component of type.
Cold heading technique is mainly characterized by without machining, and stock utilization is high, utilization rate is up to 80～90%, and metal material Stream line will not be cut off, therefore product intensity is higher than machining or casting part strength, give birth in certain batch Under the conditions of product, cold-heading processing cost is more much lower than other processing costs, it is adaptable to generally need cutting members and securing member etc. The Product processing of symmetrical shape.The dimensional accuracy of product, weight accuracy and mechanical property etc. are attained by higher requirement.
Lubricant should have the special feature that：Good carrying wear resistence, Squeezing ground (not plucking, pull, effectively extend punch die Service life), low temperature flow diffusivity, lubricity, cooling, film strength is big, oil film thickness keeps stable, free from extraneous odour, no Stimulate skin, improve fineness, protect part to be processed surface not corrosion and oxidation, reduce power consumption, low temperature flow is good, Good anti-foaming property, resistance to emulsion, thermal oxide are qualitative good, reduce the generation of sediment and paint film, profiled member easy cleaning.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of with good carrying wear resistence, Squeezing ground, low temperature flow Diffusivity, lubricity, cooling, film strength is big, oil film thickness keeps stable, free from extraneous odour, does not stimulate skin, can improve bright and clean Degree, protect part to be processed surface not corrosion and oxidation, and reduction power consumption, low temperature flow are good, good anti-foaming property, anti-breast The property changed, thermal oxide are qualitative good, reduce the generation of sediment and paint film, the vanadium alloy cold heading technique lubricant group of profiled member easy cleaning Compound.
The present invention employs the following technical solutions solution above-mentioned technical problem：
A kind of vanadium alloy cold heading technique lubricant compositions, using oil based on 400 base oils of HVI, coordinate various multiple Close additive, its each mass percent into being grouped into：
