Connecting rod is the key part of car engine parts, is also a typical and important complex closed die forging parts.Manufacturing fine degrees,inner and outer quality of connecting rods will directly affect the engine performance and level.Connecting rod causes high-frequency alternating stress inside in the high speed run up process of engine.It will have to bear shock pressure detonated by every stroke gas in cylinder and crankshaft torsional inertia force.When the hair motor's speed is 3000 ~ 5000 r/min, the loading frequency is very high.Because the connecting rod is working at high speed under the fatigue load,so,there is high requirement on the strength of the connecting rod.In addition,due to keep the crankshaft always operate at a high speed in an equilibrium state,so the weight of the connecting rod must also be controlled in a certain range.
Plastic forming and machining process of connecting rod are difficult,for the purpose of this forging production and machining process,which it is easy to appear the quality problem.The occurrence of these quality problems involve many factors. So for a long time,drop forging manufacturers are always continuously improving and discussing the material,forging process and mechanical processing manufacturing technology.Its purpose is to satisfy thetechnical performance and use requirements of products,and to be able to reduce costs,improve efficiency and increase economic benefits to the greatest extent at the same time.
anyang have build many closed die forging lines for connecting rod
this connecting rod line is we build for one Japan forging plant, they forge the connecting rod for Honda Auto
connecting rod dimension and weight tolerrance requirements very high
the connecting rods forge one our CNC forging hammer can 100% meet the customer requirements, Till now, the forging line has run about 5 years, the running condition very well.
if you want to learn more about the connecting rod forging machine, please contact me feel free on online or send email to info@chinesehammers.com
Test production connecting rod in anyang workshop and acceptance inspection:
