Abstract
The present invention discloses a surface coating layer used for cold extrusion shaped metal pipe fitting stocks, which is formed by mixing three components of gypsum, machine oil and lubricating grease according to a weight ratio 1: (3 to 10): (0.1 to 0.8), wherein a main component is hydrous calcium sulfate (CaSO4.2H2O), and a granularity requirement is not less than 300 meshes; the machine oil is easy to lubricate, and the lubricating grease is a meltable solid binding agent; the thickness of a surface coating layer is from 100 to 250 mum. The present invention is harmoniously coated on the outer surface of a pipe blank to be processed by cold extrusion molding or to be transformed by bearing force, and a processed product has the advantages of homogeneous surface quality, no sprain, no sprain of a mold, few vibration degreasing process step and low cost, and is widely suitable for processing extrusion shaped metal products.
Description
One, technical field
The present invention relates to a kind of face coat that is used for cold extrusion shaped metallic article, specifically a kind of face coat that is used for cold extrusion shaped metallic conduit accessory material base of easy to clean.
Two, background technology
At present, the coating kind that adopts in the hot pressing both at home and abroad or metallic conduit accessory moulding (stress deformation) process of colding pressing is a lot, there is certain hidden danger in the coating in past to environmental protection and health aspect, and easy to clean not, there is certain defective in the surface quality of processing rear tubular member (road), and mould is easily pulled.Such as used chlorinated rubber of past+toluene coating, a kind of pungent taste is arranged, in this environment, can certain harm be arranged for a long time to human body; And this kind coating volatilizees easily, easy to clean not, and can making not in the solid solution process, the residue of easy to clean forms the piebald defective on the pipe fitting surface; Simultaneously also can constitute certain threat to safety.Used for another example 566B glue, volatilization is exceedingly fast, and uses discharging meeting later that surrounding enviroment are caused certain harm.
Three, summary of the invention
The object of the present invention is to provide a kind of face coat that is used for cold extrusion shaped metallic product, after this face coat coating moulding, need not vibrate cleaning and degreasing, can avoid mould to pull, product surface does not have to be pulled, and has improved product quality.
The objective of the invention is to be achieved through the following technical solutions:
A kind of face coat that is used for cold extrusion shaped metallic product is characterized in that: described face coat is 1 by gypsum, machinery oil, three kinds of components of lubricating grease by weight: (3 ~ 10): (0.1 ~ 0.8) mixes.
Among the present invention, described gypsum main component is hydrous calcium sulfate (CaSO42H2O), and its granularity requirements is for being not less than 300 orders.
Described machinery oil is an oils easy to lubricate, comprises hydraulic oil, the lubricating oil of all kinds of trades mark.
Described lubricating grease is can be at the solid-state binding agent of 200 degree fusings.
The thickness of described face coat can be 100-250 μ m.
The present invention is a kind of coating for surface protection that is used for cold extrusion shaped goods of easy to clean; during use; apply this coating equably at the metal tube blank outer surface for the treatment of cold extrusion shaped or stress deformation; in cold extrusion (stress deformation) process; prevent well on metal pipe surface because pull on the pipe surface of causing in extruding or the loading process because it is evenly distributed on, and has reduced the reprocessing of later process (grinding).Because this coating oils when the solid solution operation melts easily, and does not stay foreign material on the pipe fitting surface, reduce the surface because surperficial piebald defective and the minimizing vibration degreasing process that exists dirt when heat treatment, to cause.Main component of the present invention is CaSO42H2O, oils, and fatty binding agent etc., melts easily running into 200 oils when spending, and this coating is easy to come off, and comes off thoroughly, does not leave a trace.
Compared with prior art, the present invention has following advantage: 1, the metallic article surface quality does not evenly have and defective such as pulls; 2, the present invention easily comes off, can thoroughly clean than other coating; 3, because even this coating of coating in pipe surface, effectively avoid since the intrinsic defectives such as burr in pipe surface in extruding or stress deformation process to pulling that mould brings, effectively protect mould, prevent that mould from pulling; 4, use cost is low, and all kinds of raw materials of the present invention are easier to buying and cheap.5, this coating can be avoided bringing injury to human body, and pollution on the environment, belongs to Green Product.
