Crankshaft 3908031 Fits for Cummins Engines 4BT3.9 Diesel Engine
Mainwe-Engine was founded in 2010, is a worldwide refutable engine overhaul gasket manufacturer in China, our main products include engine overhaul gasket sets, cylinder head gaskets, and manifold gaskets or range of Cummins diesel engine vehicles. At the same time, we also supply Genuine and OEM spare parts for Cummins engines like cylinder, Crankshaft, camshaft, shaft bushing, connecting rod, cylinder body, cylinder cap, water pump, oil pump, cylinder sleeve, piston, piston ring… All of them have exported to the United States, Russia, South America, Middle East, Southeast Asia and covering over 20 countries and regions.
Forging technology
The automatic production lines with hot die forging press and electro-hydraulic hammer as the main engine are the development direction of crankshaft forging production. These production lines will generally adopt advanced technologies such as precision cutting and blanking, roll forging (wedge cross rolling), medium frequency induction heating, finishing hydraulic press precision pressing, etc. at the same time, they will be equipped with auxiliary machines such as manipulator, conveyor belt and die change device brought back to the turntable to form flexible manufacturing system (FMS). Through FMS, the workpiece and die can be replaced automatically, and the parameters can be adjusted automatically, which can be measured continuously in the working process. Display and record the forging thickness and maximum pressure data, and compare with the fixed value, select the best deformation to obtain high-quality products. The central control room monitors the whole system to realize unmanned operation. This method can improve the internal fatigue strength of crankshaft by more than 20%.
