In recent years, in order to meet the needs of security and energy-saving and emission-reduction (loss of weight), high-strength vehicle steel receive widespread attention.Due to the raising of intensity rank, traditional cold stamping forming technique cannot overcome the dimensional accuracy of the resilience after high strength steel shaping and guarantee auto parts.Hot forming can utilize high strength steel to carry out production complex component, is shaped and quenches to carry out simultaneously, realizes high strength by phase transformation strengthening.Part tensile strength after high-strength steel is hot press-formed can reach 1500MPa and more than, while energy-conservation loss of weight, meet security requirement.Hot forming techniques has become the forward position practical technique of automobile manufacturing field.
Hot press-formed blank needs to be heated to austenitizing and is incubated a period of time, leans on radiation and Convective Heating in usual stove, walking beam furnace or batch-type furnace at the bottom of roller now.Owing to be there is considerable influence by the thickness of heating steel sheet and coating and radiation coefficient to heating, cause the heater length in suitability for industrialized production very long (except batch-type furnace, but it controls comparatively complicated, and policy control comparatively bothers).Reality also has method such as Fast Heating such as employing electromagnetic induction heating and infrared heating etc.Independent employing electromagnetic induction heating needs suitable coil, and the bad and electromagnetic induction heating of Flexible Equipment efficiency of heating surface after higher than Curie-point temperature obviously declines.Certain university have employed electromagnetic induction heating and electric furnace composite heating method, but there is the shortcomings such as Flexible Equipment is bad equally.Infrared heating is generally applied and food industry, but be also employed to heat with steel plate, adopt separately infrared heating steel plate generally to apply and local heat, and lower than austenitizing temperature, even if steel plate is whole be subject to infrared heating, still there is plate temperature homogeneity this shortcoming poor.
Summary of the invention
The technical problems to be solved in the utility model is to provide three-dimensional nonstorage calorifier and the heating means of the hot press-formed blank that a kind of structure is comparatively simple, floor space is little and the efficiency of heating surface is high, not only increase blank temperature uniformity, also improve the efficiency that more than curie point heats.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of three-dimensional nonstorage calorifier of hot press-formed blank, comprise the first heating clamber and the second heating clamber, this first heating clamber and the second heating clamber are equiped with the first heatproof conveying mechanism and the second heatproof conveying mechanism respectively, described first heating clamber is provided with multiple infrared heating fluorescent tube for heating blank along the first heatproof conveying mechanism, and described second heating clamber is provided with the electric furnace for heating blank.
Preferably, the outside of described infrared heating fluorescent tube is equiped with reflector.
Preferably, described multiple infrared heating fluorescent tube parallel arranged is arranged.
Preferably, the feed direction of described first heatproof conveying mechanism and the second heatproof conveying mechanism is contrary.
Preferably, described first heating clamber is positioned at directly over the second heating clamber, or described first heating clamber is positioned at immediately below the second heating clamber.
The beneficial effects of the utility model are: the utility model provides a kind of three-dimensional nonstorage calorifier and heating means of hot press-formed blank, adopt infrared heating that blank is heated to 800 degree from room temperature and also only need about 10s, there is no the restriction of curie point compared to electromagnetic induction heating, and blank self-temperature its firing rate higher and efficiency all can improve.The utility model in actual applications, first adopts infrared ray to be heated rapidly to about 800 degree or higher, then adopts electric furnace radiation heating to carry out follow-up intensification and insulation, make plate homogeneous temperature.Infrared heating and heating by electric cooker combine, and three-dimensional stacking, has the following advantages: not only effectively improve the efficiency of heating surface, saves the energy, enhances productivity, reduce costs; Further improve the uniformity of plate Temperature Distribution, make product quality better; A large amount of minimizing can firing equipment floor space especially, and reduce costs, practicality is strengthened greatly.
Accompanying drawing explanation
