簿板形工件热处理淬火时不易操作,碎火后极易变形,须增加校直及去应力回火工序,这既延长了生产周期,又增加了电能消耗。为了提高薄板形工件的质量,提高热处理工作效率,我们对图1所示的厚度为2mm的工件进行了普通加热淬火。淬火后,工件的变形率由原来的百分之百降至百分之一,淬火后不再需要校直工 Sheet shaped workpiece heat treatment is not easy to operate quenching, crushing fire easily deformed, to be increased straightening and stress relief tempering process, which not only extends the production cycle, but also increased energy consumption. In order to improve the quality of sheet metal workpieces and improve the efficiency of heat treatment work, we performed the ordinary heating quenching on the workpiece with the thickness of 2mm as shown in Fig.1. After quenching, the deformation of the workpiece from the original one hundred percent reduced to one percent, after quenching no longer need to straighten
