以3150吨热模锻压力机为主体的连杆锻造生产线,是锻造厂解放牌汽车换型改造的重点项目之一,用于生产6102发动机连杆锻件,年生产50万件。锻件形状如图1。一、加工工艺及设备3150吨锻压机连杆锻造生产线的工艺是将杆体与杆盖整体锻造,其工艺流程是:毛坯由中频感应电加热机床加热→自动辊锻机制坯→3150吨锻压机成形(预锻、终锻)→315吨切边压床切边、冲孔→热处理(余热淬火、回火炉回火)→抛丸清理→硬度检验→荧光探伤→冷校正。锻件成形各工步如图2、图3所示。
To 3150 tons of hot forging presses as the main connecting rod forging production line, forging plant Jiefangpai car one of the key projects for the transformation, for the production of 6102 engine connecting rod forgings, the production of 500,000. Forgings shape shown in Figure 1. First, the processing technology and equipment 3150 tons forging press connecting rod forging production line is the process of the rod body and lever cover forging, the process is: rough by induction heating electric machine → automatic roll forging billet → 3150 ton forging press forming (Pre-forging, final forging) → 315 tons trimming press trimming, punching → heat treatment (residual heat quenching, tempering tempering) → shot blasting → hardness testing → fluorescence detection → cold correction. Forging the various steps shown in Figure 2, Figure 3 shows.
