Research On The NC System Of The Machine For Notching Fracture Splitting Notch In The Connecting Rod By Laser

Connecting rod is the key part of vehicle engines. It works under high frequency tired load condition. Connecting rod is to hard too smithing and Processing it. So the world gave high attention to its technology and manufacture method. The fracture splitting technology of connecting rod is producing crack designedly to rough big hole of the holistic smithing connecting rod. So it can form initial notch, and achieve the intention of separating the connecting rod noumenon and the cover of connecting rod. It changes the conventional processing method of connecting rod at all. It is a grand renovation to the conventional processing method of connecting rod, Achieving new breakthrough in manufacturing connecting rod. It is very important to realize high precision and efficiency, low cost and automatization in producing connecting rod, possessing good development potential.Fracture splitting manufacture technology needs three pivotal working procedures: manufacturing fracture splitting notch, fracture splitting, fixing bolts. Fracture splitting notch in the connecting rod is the key pivotal working procedure of the fracture splitting manufacture technology, so its figure, size and the way of manufacturing influence the power of fracture splitting and the distortion of the big hole.The laser processing has merits that are narrow splitting notch, fast velocity, no abrasion, easy splitting and high repeated precision. Manufacturing the fracture splitting notch by laser can reduce the pollution to environment without the cooling equipment of emulsification liquid. Meanwhile, the precisions of...
