我厂锻造的左盖锻件形状如图1,材料20钢,数量大且质量要求高,在160吨摩擦压力机上使用浮动式凹模进行温锻成型。经使用证明,浮动式凹模可以使工件变形均匀,压1～2次成型,平均生产速度达到100件/小时,温锻质量稳定,一次合格率达99％以上,表面光洁,为一级精度锻件。模具结构如图2所示。采用模口导向,保证了上下模的同轴度。凹模是可动的,靠四个均布弹簧浮起,在不 Forgings left forging I shape forgings in Figure 1, material 20 steel, a large number and high quality requirements, in the 160-ton friction press floating die for warm forging molding. The use of proven, floating die can make the workpiece deformation uniform, pressure 1 or 2 times molding, the average production speed of 100 / hour, warm forging quality and stability, a pass rate of 99% or more, smooth surface, a precision Forgings. Mold structure shown in Figure 2. Using die-oriented, to ensure the coaxiality of the upper and lower mold. The die is movable, floated by four evenly distributed springs, no
