Abstract
The invention relates to a deep drawing process of an austenitic stainless steel plate, which comprises the following steps of: (1) carrying out surface protection on the external surface of a blank or a semi-finished product of the burr-free austenitic stainless steel plate before deep processing: firstly, cleaning the blank or the semi-finished product by using wash gasoline, washing with a diluent, drying, and painting by using clear laquer to 8-10 mum in thickness; (2) coating a lubricant on the surface of the blank or the semi-finished product of the burr-free austenitic stainless steel plate in contact with the corresponding position of a female die during deep processing; and (3) determining the deep processing times according to the drawing coefficient of the blank or the semi-finished product of the burr-free austenitic stainless steel plate, and deep drawing to mold the part; adding a thermal processing technology between the deep drawing procedures until an alpha phase is remained in an austenitic structure to form a single-phase structure, and carrying out painting protection on the external surface of the blank or the semi-finished product of the burr-free austenitic stainless steel plate prior to each time of deep processing. The process of the invention effectively reduces scratches on the surface of the part and abrasion on a die, is simple and convenient to operate and has low cost and good deep drawing effect.
Description
Technical field
The present invention relates to a kind of austenite stainless steel plate deep-drawing technique.
Technical background
The yield point height of austenitic stainless steel, the hardness height, the work hardening phenomenon that material is caused by the plasticity drastic deformation in drawing process is very serious, and because part and die surface all are rough matsurfaces, in drawing process, be prone to the sticky lump phenomenon, make material adhesion at the die working surface, cause piece surface to produce and draw trace, die entrance place and the die cavity inner-wall material place of flowing through at mould also can supervene plucking, seriously undermined die life, and influence the surface quality of product, this phenomenon is ubiquitous problem in the austenite stainless steel plate deep-drawing technique.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can effectively reduce the austenite stainless steel plate deep-drawing technique that piece surface draws trace and reduces die wear under the prerequisite of mould not being improved and changing.
It is as follows that the present invention addresses the above problem the technical scheme that is adopted:
Austenite stainless steel plate deep-drawing technique of the present invention may further comprise the steps:
(1) before the pull and stretch carrot-free austenite stainless steel plate blank or half-finished outer surface are carried out surface protection: at first described blank or semi-finished product are cleaned up with washing gasoline, clean with diluent again, after the drying, with the varnish spraying, coating thickness is 8 ~ 10 μ m;
(2) lubricant is spread upon on the described austenite stainless steel plate blank or surface of semi-finished that is contacted with the die corresponding site during pull and stretch;
(3) determine its number of drawing according to austenite stainless steel plate blank or half-finished drawing coefficient, pull and stretch makes forming parts; Between drawing sequence, increase Technology for Heating Processing, be retained in mutually in the austenite structure and form homogeneous structure until α, before each pull and stretch all to the protection of spraying paint of austenite stainless steel plate blank or semi-finished product outer surface.
Described diluent is alkyd diluent or acrylic diluents, and described varnish is alkyd varnish or acrylic lacquer, and described varnish is alkyd varnish when diluent is the alkyd diluent, and described varnish is acrylic lacquer when diluent is acrylic diluents.
Described lubricant is the mixture of machine oil and molybdenum bisuphide.
Described Technology for Heating Processing is carried out stabilization processes for carrying out earlier after the solution treatment again, is about to woolen cloth and is heated to 1000 ~ 1150 ℃, sharply cooling in air then.
Described Technology for Heating Processing is carried out stabilization processes for carrying out earlier after the The high temperature anneal again, is about to product and is heated to 850 ℃ ~ 900 ℃, sharply cooling in air then.
The obtained beneficial effect of the present invention is: before the technology pull and stretch of the present invention to the spray paint protection and effectively reduced the cut of piece surface as lubricant and to the wearing and tearing of mould of austenite stainless steel plate blank or surface of semi-finished with the mixture of machine oil and molybdenum bisuphide.Process annealing heat treatment mode routinely can not satisfy the quality standard of austenite stainless steel plate pull and stretch product in the past, and part scratches serious, and mould side wall also has the plucking phenomenon, greatly reduces the service life of mould.Between technology drawing sequence of the present invention woolen cloth is heat-treated operation, can eliminate the intercrystalline corrosion phenomenon, obtain single-phase austenite laminar tissue, reach softener material and recover the purpose of its plasticity, thereby reduce the scuffing of piece surface and the plucking phenomenon of mould side wall.Solution treatment can be eliminated the material stress uneven phenomenon, and makes material softening, avoids the injury to mould side wall effectively; Stabilization processes can improve the corrosion resistance of material, repeats quenching times and is no more than twice, and the semi-finished product section behind the drawing and forming does not have burr, the seamed edge abate.Technological operation of the present invention is easy, cost is low and pull and stretch is effective.
