How to avoid oxidation problems of forging parts

Due to the forging parts is produced by forging process, so the forging can be divided into hot forging and cold forging, hot forging is above the metal recrystallization temperature forging, raise the temperature can improve the plasticity of metal, improve the immanent quality of workpiece, make its not easy cracking, high temperature also reduces the metal deformation resistance, and reduced the tonnage of forging machinery required, however, there are a lot of hot forging process, The workpiece precision is poor, the surface is not smooth, the forging parts are easy to oxidize.

Cold forging pressure is below the metal recrystallization temperature of forging, cold forging pressure refers to the normal temperature of the forging, and higher than the normal temperature, but not over the recrystallization temperature forging pressure, used to warm forging pressure, so warm forging precision is higher, more smooth surface, resistance to deformation ability is not strong, the temperature of the cold forging forming of forging pieces of shape and size precision is high, because the surface is smooth, Many cold forging and cold stamping parts can be used directly as parts or items without cutting. However, large forgings may break during forging and pressing, so large tonnage forging presses are required for processing.
In order to complete the forging a heating forging task, initial forging temperature and the final forging temperature of hot forging, the temperature range between should be as large as possible, however, if the initial forging temperature is too high, too much metal grain growth will not form overheating phenomenon, it will lower the quality of forging, the understanding to the heavy duty truck axle head forging manufacturing plant, Comprises a housing and an intelligent operation arranged on one side of the housing.
Heavy duty truck axle head forging pieces of manufacturing equipment, can be used for high precision forging various shaft forging parts, machining allowance is small, energy efficient, use hot forging workpiece is big and thick, materials with high intensity, low plasticity, when the metal is enough plasticity and the deformation is not big, or the total deformation of the forging process and use, is advantageous to the plastic deformation of metal, usually do not use hot forging, Cold forging is used instead.
