摘要：
Connecting rod crackingprocessing is a key technology for connecting rod processing, which contains many advantages, such as fewer processing procedures, which can minimize equipment investment; the material loss is low, which can achieve the effect of energy saving and material saving; and the products have higher quality and improve the carrying capacity of connecting rods. Its core technologies include three types, the first is connecting rod cracking groove processing, the second is the directional splitting connecting rod, and the last is fixed torque assembly bolts. The main processing method of connecting rod cracking groove processing is laser processing. This article mainly introduces the principle and characteristics of laser processing connecting rod cracking tank and the development status, and characteristics and prospects of laser processing connecting rod cracking tank equipment at home and abroad. The characteristics of laser processing connecting rod cracking tank are mainly high precision and high efficiency. At present, domestic and foreign laser processing connecting rod cracking tank equipment is developing in the direction of improving processing efficiency and reducing costs.
