Laser assembly solder plate is used widely on vehicle body, but laser assembly solder plate material exists violent change on thickness.The sheet material that different material is thick is on the one hand when welding, and position while welding exists thermal stress, and bonding strength is not good, and welded seam area transmission force property is unstable; Require higher to Design of Dies during punch forming simultaneously; On the other hand when collision accident occurs, violent change position can produce stress concentration phenomenon, thus causes part breaking, causes driver and crew's injury in car larger.
Along with the development of heat stamping and shaping technology, heat stamping and shaping part is also applied at vehicle body, to playing great role alleviating pts wt and improve in bus body strength simultaneously.Part material integral quenching in the process of temperature decrease in heat stamping and shaping process, greatly improve shaping after part strength, but segmentation strengthening can not be carried out to the parts of zones of different.As shown in Figure 1, hot forming tool comprises die 1 and punch 2, is provided with part 3 to be processed between die 1 and punch 2.After plate is heated to more than critical-temperature 30 DEG C to 50 DEG C, insulation a period of time, makes its austenitizing, be put on mould, by the interaction of die 1 and punch 2, through pressurize, cool the draw forming of part 3.Hot forming tool adds complicated pressure-retaining system, cooling control system compared with traditional moulds, but total form or overall die 1, overall punch 2, consistent with traditional moulds structure.Because the plate of processing parts is uniformity, so the material property of the part each several part of thermoforming production is basically identical, part strength entirety is higher.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of mould structure of selective hardening, allows part in intensity distribution, reach the effect of laser assembly solder plate part, i.e. zones of different part strength reasonable distribution as required, but sheet thickness is constant; Specifically thermoforming punching press basis on, the part that strength demand is little on same part is incubated it, allows its temperature slowly decline; The part that strength demand is high is allowed to condition at selective hardening under quenching environment, improves intensity; Different temperatures environment, is arranged by the difference of the different piece of die in punching course or punch and realizes.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of mould structure of selective hardening, comprise punch and die, described die is located at above punch, described punch or die are provided with heating control system and cooling control system, punch or die are separated by described heating control system and cooling control system in the vertical direction, described cooling control system comprises the cooler being located at outside and the second runner be located in punch or die, described cooler is connected by the second tube connector with the second runner, described heating control system comprises the heater being located at outside and the first flow be located in punch or die, described heater is connected by the first tube connector with first flow.
Wherein, described first flow cross sectional shape divides identical with corresponding Components.
Wherein, described second runner cross sectional shape divides identical with corresponding Components.
The beneficial effect of technique scheme of the present utility model is as follows:
Such scheme, for monoblock type consistency of thickness and the Element Design of rigidity reasonable layout provides implementation method; The part produced has good rigidity, intensity, ensure that vehicle body crash requirements, available protecting occupant safety; Weight alleviates greatly, achieves body lightening requirement, reaches the object reducing energy resource consumption; Avoid the various drawbacks that laser assembly solder plate in prior art produces because of abrupt changes in thickness; Avoid the part that in prior art, thermoforming is produced, integral rigidity is consistent, does not have the defect in energy-absorbing buffering district.

Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The various drawback problem that the utility model produces because of abrupt changes in thickness for laser assembly solder plate in prior art and the part that thermoforming is produced, integral rigidity is consistent, does not have the problem in energy-absorbing buffering district, provides a kind of mould structure of selective hardening.
As shown in Figure 2, the mould structure of a kind of selective hardening that the utility model embodiment provides, comprise punch 2 and die 1, described die 1 is located at above punch 2, described die 1 is provided with heating control system 11 and cooling control system 12, and die 1 is separated by described heating control system 11 and cooling control system 12 in the vertical direction., punch 2 is consistent with existing mold, is monolithic construction.Die 1 is divided into two parts, after plate is heated to more than critical-temperature 30 DEG C to 50 DEG C, insulation a period of time, makes its austenitizing, is put on mould, apply pressure to mould.Being provided with the part part corresponding to the die 1 of heating control system 11, being incubated by heating control system 11, controlling its temperature reducing rate; Being provided with the part part corresponding to the die 1 of cooling control system 12, due to mould own temperature, adding the effect of cooling control system 12, forming quenching environment.
