Description

A kind of heat stamping and shaping method of electrogalvanized steel plate or steel band
Technical field
The present invention relates to metal material field, autobody sheet's forming field is primarily adapted for use in, is a kind of heat punching The forming method of laminated steel and steel band, is mainly used in the structures such as manufacture automobile B-column, door anti-collision joist, bumper Part part.
Background technology
Automobile " lightweight " can directly reduce discharge, reduce oil consumption, be the target of current auto manufacturing's development. The application of high-strength steel and superhigh intensity turns into one of mainstream development trend of automobile manufacturing field, but due to superhigh intensity Steel plate easily occurs the problems such as shape defect, machine-shaping load are high, springback capacity is big when carrying out cold working, and influence is super The use of high-strength steel sheet, therefore heat stamping and shaping is a kind of important way for realizing super-high strength steel product.
The existing main technological process used of heat stamping and shaping technology for：Select special drop stamping material → blanking → plus Heat insulation (steel plate complete austenitizing) → be quickly moved to quenching cooling while mould → completion shaping, finally Obtain superhigh intensity stamping parts (being organized as martensite, intensity 1500MPa or so even more highs).Existing heat punching Transfer moulding method mainly has two kinds, i.e., direct drop stamping and indirect drop stamping.
In direct hot stamping method, steel plate is heated to the temperature higher than austenitizing temperature, and is incubated a timing Between steel plate is reached complete austenitizing.Afterwards, the steel plate of heating is transferred to mould and wherein with one One-step forming technological forming is finished component and by means of the cooling of mould, (cooling velocity of mould is more than steel plate simultaneously Critical cooling rate) realize and harden.
In indirect hot stamping method, first with multi-stage molding technique, element is molded to being almost fully finished (one As be it is preforming 90%).Almost molded element is put into heating furnace again and is heated to complete austenitizing and protects Warm a period of time.The element of heating is transferred in the mould of element final size afterwards, needed exist for especially It is to be noted that the thermal expansion of the element of advance comprising need to be considered.After specifically cooling mould terminates, advance comprising Element in a mold to be cooled down more than the cooling rate of critical cooling rate so as to reaching hardening.
Direct hot stamping method is easier to realize, but only allows production relatively simple part in shape.Indirect thermal Sheet Metal Forming Technology is more complicated, but can produce the part of more complicated shape simultaneously.
In addition, traditional can cause stamping steel plate skin decarburization in heating process without coating heat-punch member and aoxidize Skin.To avoid the oxidation and decarburization of drop stamping surface of steel plate, drop stamping steel plate is set to possess heat-resisting quantity and corrosion resistance, The coating technology for being suitable for drop stamping steel is developed at present.Current drop stamping coating is main by aluminium silicon cladding (Al-10Si) coating, hot pure zinc plating (GI) coating, alloying zinc-iron (GA) coating and plating zinc-nickel (Zn-10Ni) Coating etc..
And in direct hot stamping operation, the Zn-based plating layer drop stamping steel of cathodic corrosion protection can be provided, due to LME effect can cause to produce micro-crack (10um to 100um) in steel matrix, or even may extend to whole plate The macroscopic cracking in thick direction, therefore hinder the application and development of zinc-base drop stamping clad steel sheet.Rushed using indirect thermal During pressure technique is hardened after subsequent shaping, the quantity of matrix cracking can be reduced, but equally can not Crack prevention, The production cost of part is improved simultaneously.Just because of this, so far, drop stamping of the Asia without Zn-based plating layer is used Steel application, and have a preference for and use aluminium/silicon cladding.
