电磁振动给料机是用于连续生产线中的输送物料的重要器械设备,板簧是电振机中主要承载构件;由于对这类设备的可靠性和寿命要求较高,同时板簧的振动频率高(3000次/分),受力复杂(拉伸和弯曲),故板簧的设计应力较低(<13kgf/mm~2),片数多,重量大,并且在超振幅过载情况下,板簧寿命低,因此需进一步提高板簧的强韧性和疲劳寿命。形变热处理是利用形变强化和相变强化相结合的综合强化工艺,它可以赋予材料或零件用单一强化方法所不能达到的综合性能,从而有效地发挥金属的强韧性潜力。故对电振机板簧进行了高温形变
Electromagnetic Vibrating Feeder is an important equipment for conveying materials in the continuous production line. The leaf spring is the main bearing component in the electro-vibration machine. Due to the high reliability and longevity requirements of such devices, the vibration frequency High (3000 beats / min), the force is complex (tensile and bending), so the design of the leaf spring stress is low (<13kgf / mm ~ 2), the number of films, weight, and overload conditions, Leaf spring life is low, so the need to further improve the leaf spring toughness and fatigue life. Deformation heat treatment is the use of a combination of deformation strengthening and phase transformation strengthening comprehensive strengthening process, which can give the material or parts with a single strengthening method can not achieve the overall performance, so as to effectively exert the metal’s toughness potential. So the electrical vibration machine spring high temperature deformation
