Abstract
A technology for coating a composite lubricating film on the surface of blank to be cold forged includes degreasing the blank, immersion corrosion, activating by Ti salt, phosphorizing-saponifying to form a phosphorized film, drying, and vibration-typ coating of solid lubricatn (graphite or graphite plus MoS2).
Description
Technical field
Thereby the present invention relates to a kind of method that kollag forms composite lubricated film that applies of after cold forging is with the saponification of blank surface phosphatization, vibrating again.
Background technology
In order to reduce the cold forging flow resistance of metal stock in deformation process, guarantee that blank can be full of die cavity, reduce die wear, before carrying out cold-forging techniques such as cold pendulum is rolled over, cold rolling extends to cold-heading, need carry out the phosphatization saponification to blank and handle, make blank surface generate one deck phosphating coat.Phosphating coat is a loose structure, and porosity reaches 20%, and coefficient of friction is very little, has well to hold oiliness, thereby is forming cushion on the contact-making surface between blank and the mould, can reduce the frictional resistance and the die wear of blank deformation effectively.But along with the quickening with rhythm of production of improving constantly of Cold Forging energy, the antifriction efficiency of phosphating coat is difficult to satisfy instructions for use, so, in process of production, still need again the cold forging mould surface coating lubricating oil or apply kollag to be lubricated.This has not only increased operational sequence, has reduced production efficiency, is more seriously to cause blind hole and gap obstruction, die cavity to pile up easily, causes waste product to produce.
Summary of the invention
The present invention is directed to the cold forging mould surface coating lubricating oil or apply kollag and be lubricated the problem that operation increases, production efficiency reduces and be easy to generate waste product that causes, the object of the present invention is to provide a kind of semifinished product composite lubricating film coating method for cold forging, this method has improved production efficiency, has reduced the wearing and tearing of mould.
To achieve these goals, technical scheme of the present invention is: semifinished product composite lubricating film coating method for cold forging is characterized in that the cold forging blank, after adjusting through degreasing etch preliminary treatment, titanium salt activation, carry out phosphatization-saponification and handle formation thickness 8～12 μ m, the heavy 16-23g/m of film
2Phosphating coat, drying gets surperficial blank with one deck phosphating coat; The blank that then surface is had one deck phosphating coat is put into the coating that the oscillatory type coating machine carries out kollag, adds graphite or graphite+MoS in the oscillatory type coating machine
2Kollag, its addition be in the oscillatory type coating machine surface have one deck phosphating coat blank quality 10%～50%, coating machine is by inclined plane spiral rotation form vibration 10-30min, rotating speed 60～480r/min, kollag is attached on the phosphating coat outside equably, part is infiltrated among the hole of phosphating coat of loose structure, forms to have double-deck cold forging with semifinished product composite lubricating film (promptly getting product).
The described blank that the surface is had one deck phosphating coat is put into the coating that the oscillatory type coating machine carries out kollag, for once putting into 60～500 of the blanks that the surface has one deck phosphating coat, every heavy 100～1000g.
Described kollag is graphite and MoS
2The time, graphite: MoS
2Mass ratio=1: 1～5.
Cold forging with the operation principle that the anti-attrition that rubs falls in semifinished product composite lubricating film is: in forming process, the surface area of cold forging blank constantly increases, and phosphating coat is torn out, the blank metal that exposes directly contacts with die surface, the coefficient of friction of this part increases suddenly, flow difficulties, wearing and tearing aggravation.And vibration is coated in the kollag on the phosphating coat, in blank deformation, a part can continue to be attached on the blank phosphating coat and tear the exposed region surface, another part then is scattered on the profile of blank deformation equably, between blank and mould, form the second road cushion, thereby remedy the tear zone of phosphating coat effectively, coefficient of friction reduction, the abrasion of exposed region are reduced.The present invention both can make production efficiency not be lowered, and can not cause at the die cavity place again to pile up to cause waste product.
Cold forging of the present invention can delay the wearing and tearing (promptly reduced the wearing and tearing of mould) of cold-forging die under efficient fully loaded transportation condition effectively with semifinished product composite lubricating film, and in the service life of having improved cold-forging die, Cold Forging efficient improves 50%-200%.The cold forging semifinished product composite lubricating film that this method obtains can adapt to peculiar violent shock loading of cold-forging technique and very high bearing stress, and the characteristics of the long displacement of the large deformation of blank, has also satisfied the high requirement of Cold Forging production efficiency.
