Description
Technical field
The utility model is related to drop stamping plate heating art, more particularly to a kind of drop stamping plate heating mechanism.
Background technology
Drop stamping is a kind of manufacturing process for obtaining and possessing excellent performance stamping parts, and process is high strength steel plate
(22MnB) is heated to austenitizing temperature and keeping the temperature makes austenite homogenize, and then moves quickly into diel, in mold
Upper completion punching course and pressurize quenching, finally obtain high-strength steel pressing of the tissue morphology based on martensite.Drop stamping work
The advantages of skill, is in punching course that resistance of deformation is small, and gained product intensity is high, and it is small to spring back opposite cold-stamped part.
Influence of the variation of plate temperature to drip molding quality is notable in its forming process.Since the cooling rate of plate exists
It is non-uniform in entire punching course, heat when high temperature between plate and mold is transmitted very fast.Just start in punching course
When, punch-nose angle and die entrance touch plate at first, make at this time due to there is the huge temperature difference between plate and mold
Heat transfer is violent and falls to cause to decline acutely with this some materials temperature, and this some materials is made to start to turn to ferrite and pearlite
Become, so that cannot get martensitic phase when final quenching.With continuing for punching course, contacted with die entrance that
Some materials continue the sidewall sections that the flowing into mold forms stamping parts；At the same time, the material of flange section is gradually in
The heart is flowed and is contacted with die entrance, this is but also this some materials temperature declines, and then starts to turn to ferrite and pearlite
Become and makes finally to quench obtained martensite content reduction.The non-uniform cooling of the above it is final so that the fillet of drip molding and
Diffusion transformation occurs for side wall and the heat-punch member horse that keeps ferrite and pearlite content more, and final pressurize is made to quench
Family name's body content is few and nonuniform organization.
Can influence of the pressurize quenching process of drop stamping to drip molding tissue and performance be also particularly important, obtain martensite
Content is uniform, and the uniform component of performance depends on the cooling rate of plate various pieces in pressurize quenching process.Only work as plate
Cooling rate be more than critical cooling rate (for most drop stamping boron steels, this critical value is about 27 DEG C/s) when austenite
Martensite can be changed into.However in pressurize hardening phase, blank and mold contact are often non-uniform, this is because in Re Chong
The material at punch-nose angle and the material at punch-nose angle touch mold at first when pressure, this two-part material cooling rate adds
It is fast thus generate differential hardening, and during post forming, the effect of drip molding sidewall sections material tension stress and be thinned
When causing finally to mold, the side wall of drip molding cannot be completely bonded with mold shape face and there are gaps.Blank and mold contact are tight
Close local heat by convection current, radiation, pass fall diffusion thus cooling rate it is very fast, and blank and mold have gap place heat
Amount can only be propagated in the form of heat radiation and by air dielectric, therefore cooling rate is slower.The inhomogeneities of cooling rate is fallen
The uneven of tissue has been caused, so that stamping parts overall mechanical properties is uneven, it is slow in sidewall sections cooling rate, it is obtained
The martensite content obtained is low, and intensity hardness is insufficient.Therefore, there is an urgent need to one kind carrying out phase to drop stamping plate different location
Answer the heating mechanism of the heating of temperature.
