Connecting rod forging production line

Production Process

Mass production, because the first process is non-upsetting process, quality requirements of the material is general, but the end face can not have too much deformation, so the cutting is widely the use of bar shear bed. Connecting rod forging is a precision forgings, required for heating requirements is higher, heating with medium frequency induction heating furnace, the material temperature control and temperature uniformity requirements are higher, after heating generally use roll forging machine making blank, few use of cross wedge rolling process, Forging have Pre-forging and final forging, forging machine can be used for hot closed die forging press, electric screw press and CNC forging hammer, forging trimming, punching, hot precision finishing, after forging temperature control.

Process analysis

Making blank can be use roll forging machine or cross wedge rolling machine. Roller forging machine making blank is the mainstream process, the metal flow line process and the heart organization of cross wedge rolling machine is not good compared with roll forging machine, the main forging equipment CNC hammer and hot forging press precision is high,Because of CNC hammer don’t have fixed dead center. Forging accuracy is not sensitive to temperature changes, usually that the forging precision is higher, all of hot precision forging, electric screw presses, finishing machines and hydraulic press can be used for finishing, Cost-effective of electric screw press is higher.
