我厂在生产132汽车大梁成型模时,用淹水淬火法解决了大型模具淬火难的问题。这种方法很简单,把模具(T8)整个淹在水中,需淬火部位距离水面2～3mm,用焊枪火焰冲开水面,加热模具至桔红色,然后移位,利用淹没的水对加热模具进行淬火。这种淬火法,可利用现有场地和设备,方法简单,省时省工,淬火深度为2～3mm,硬度可达HRC50～55,满足- I plant in the production of 132 car beam forming mold, quenching with flooding method to solve the problem of large-scale quenching difficult. This method is very simple, the entire mold (T8) submerged in water, the need to quench the site from the water 2 ~ 3mm, with torch flame washed the surface, the mold heated to orange, and then shift, the use of submerged water on the heating mold Quenching. This quenching method, the available site and equipment, the method is simple, time-saving workers, the quenching depth of 2 ~ 3mm, hardness up to HRC50 ~ 55, to meet -
