Technical field
The present invention relates to a kind of phosphorization agent, especially a kind ofly improve drawing speed, prevent that the body surface from pulling and the signal flare body deep-draw drawing that reduces the drawing mould damage rate with phosphorization agent and preparation method.
Background technology
Iron and steel parts is handled in the phosphoric acid salt of setting (comprising that zinc phosphate, manganous phosphate, tertiary iron phosphate, calcium phosphate etc. are main body) solution; Its surface is reacted, and the treating processes of the water-fast crystal type phosphate conversion of deposition one deck film is referred to as the bonderizing of iron and steel.Phosphatize phosphate coat is made up of a series of crystal that vary in size, and on the crystalline point of contact, will form the vesicular structure of fine cracks, and this porous crystalline structure is improved the performance such as solidity to corrosion, adsorptivity, anti-attrition property of surface of steel workpiece.The purposes of steel iron phosphatising and extensive, one of them is exactly as the cold worked lubrication of iron and steel.Because the cold working of iron and steel parts comprises cold pier shaping, cold-extrusion shaping, multiple towards stretch forming and drawing forming etc.; Therefore; Need to differences such as different cold machine-shaping technology, cold machine-shaping workpiece material shapes, use different phosphorization agents and corresponding phosphating process.
But, be applied to the phosphorization agent that the signal flare body subtracts before wall deep-draw and the drawing processing at present and have following technical barrier always:
(1) seriously pull on the body surface, influences the surface quality of workpiece;
(2) the body blank is prone to crackle and scraps after repeatedly subtracting wall deep-draw drawing;
(3) the drawing mould damage rate is high, causes the mould condemnation factor high, has increased production cost of products;
(4) running speed of drawing equipment is lower, can not realize quick drawing, so labour productivity is low.
Summary of the invention
The present invention be improve drawing speed in order to solve the above-mentioned technical problem of existing in prior technology, to provide a kind of, prevent the body surface pull and reduce draw molding tool damage rate signal flare body deep-draw drawing with phosphorization agent and preparation method.

Water surplus.
The raw material and the mass ratio of said supplement are following:
The phosphoric acid 39 ~ 42% of concentration 85%
Nitric acid 9 ~ 12%
Zinc oxide 15 ~ 18%
Nickelous nitrate 0.3 ~ 0. 8%
Iron nitrate 0.05 ~ 0.2 %
Water surplus.
A kind of above-mentioned signal flare body deep-draw drawing is with the preparation method of phosphorization agent; It is characterized in that said build groove agent and all preparations as follows of supplement: the water that in stainless steel cauldron, adds calculated amount 1/3 earlier; Start agitator then; Rotating speed 40 ~ 60 commentaries on classics/min; Phosphoric acid with calculated amount; Nitric acid adds wherein; Continuously stirring 10 ~ 20min; Zinc oxide with calculated amount adds wherein slowly again; Being continuously stirring to zinc oxide fully dissolves; The nickelous nitrate that adds calculated amount again; Iron nitrate; Be stirred to abundant dissolving, the water with surplus adds wherein at last, is stirred to homogeneous transparent.
The present invention can be applicable to the phosphatization operation before the signal flare body subtracts wall deep-draw and drawing processing; On blank, can form the phosphatize phosphate coat of thickness greater than 12 μ m; Even when the deep-draw drawing between workpiece surface and the mould under the effect of the high friction of moment high temperature; Phosphorization membrane still can keep its continuous whole property; Has higher lubrication and wear resistance property; Can reduce the body surface and pull and crackle, obtain level and smooth drawing finished surface uniformly, improve product percent of pass; Can reduce and draw molding tool damage rate, prolong the work-ing life of mould, can improve drawing speed (can reach more than 3 meter per seconds) simultaneously, production efficiency is improved, reduce production cost of products.
Embodiment
The embodiment of the invention is the phosphorization agent before a kind of signal flare body subtracts wall deep-draw and drawing processing, comprises and builds groove agent and supplement, it is characterized in that:
