The production of Marine crankshaft forgings is a complex and delicate process that requires the help of a range of advanced production equipment and tools. This paper will introduce the production equipment and tools of Marine crankshaft forgings in detail, including heating equipment, forging equipment, heat treatment equipment, machining equipment and testing tools.
Heating equipment is one of the important equipment in the production of Marine crankshaft forgings. It can heat the raw material to the appropriate temperature to increase its plasticity and reduce deformation resistance. Commonly used heating equipment includes electric furnace, gas furnace, induction heater and so on. Among them, the electric furnace has the advantages of precise temperature control, environmental protection and so on, and is a commonly used heating equipment in the production of Marine crankshaft forgings.
Forging equipment is used for forging the heated billet equipment. According to the different forging process, the commonly used forging equipment includes hammering machine, hydraulic press, roll forging machine, etc. The hammer deforms the billet through the impact of the hammer head, which is suitable for small batch production. The hydraulic press exerts pressure on the billet to deform through the hydraulic system, which is suitable for mass production; The roll forging machine is suitable for the manufacture of long rod parts by continuous plastic deformation of the billet through the rotating roller wheel.
Heat treatment equipment is used for heat treatment of crankshaft forgings after forging. According to different heat treatment processes, commonly used heat treatment equipment includes quenching furnace, tempering furnace and so on. The quenching furnace is used to heat the crankshaft forgings to a certain temperature and cool them quickly to improve their hardness and wear resistance. Tempering furnace is used to heat the quenched crankshaft forgings to a certain temperature and hold them for a period of time to eliminate the quenching stress and stabilize the organizational structure.
Machining equipment is used for cutting crankshaft forgings after heat treatment. According to different processing needs, commonly used machining equipment includes lathes, milling machines, grinding machines and so on. The lathe is mainly used for turning, such as turning the outer circle and end face of the crankshaft; Milling machine is mainly used for milling processing, such as milling the keyway and boss of the crankshaft; The grinding machine is mainly used for grinding, such as grinding the outer circle and end face of the crankshaft.
Inspection tool is a tool used for quality inspection of crankshaft forgings. Commonly used testing tools include calipers, micrometers, hardness gauges and so on. Calipers and micrometers are used to measure the dimensional accuracy of crankshaft forgings. Hardness tester is used to measure the hardness of crankshaft forgings; Non-destructive testing equipment is used to detect internal defects of crankshaft forgings.
The production of Marine crankshaft forgings requires a series of advanced production equipment and tools, including heating equipment, forging equipment, heat treatment equipment, machining equipment and testing tools. These equipment and tools play an important role in the production process of crankshaft forgings, ensuring product quality and performance. With the development of science and technology and the continuous improvement of manufacturing process, the production equipment and tools of Marine crankshaft forgings will also be constantly updated to meet the production needs of higher precision and higher efficiency.
