Description

Signal flare body deep-draw drawing is with phosphorization agent and preparation method

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.
