[0002] A crankshaft is a rod-shaped mechanical component that is typically machined using rollers during mass production. A roller mill is used to initially shape the heated blank, forming the general shape of the crankshaft. Then, through multiple passes of roller forging, the various parts of the crankshaft, including the main journals, connecting rod journals, and crank arms, are gradually and precisely formed.

[0003] The crankshaft prototype moves continuously in the drum as the drum rotates. During forging, the temperature inside the drum gradually increases, and the surface temperature of the crankshaft also gradually increases. In the subsequent crankshaft forging process, the crankshaft is prone to sticking to the inner wall of the drum. After the crankshaft is formed, in order to separate the sticky crankshaft from the drum, workers need to slowly knock the crankshaft off, which consumes a lot of manpower. Utility Model Content
