Description

Technical Field

[0001] The utility model relates to the technical field of mechanical forging, in particular to a hot forging device for a vehicle output shaft. Background Art

[0002] The forging process performed above the metal recrystallization temperature is called hot forging. Hot forging is also called hot die forging. During forging, the deformed metal flows violently and the forging is in contact with the die for a long time. The metal after hot forging has better performance. The metal after hot forging often needs further processing, such as punching and other operations, which requires the use of a stamping device. However, the existing stamping device does not clean the burrs of the hot forged metal in time after punching. When the forging cools, the deformation resistance increases, making deburring very troublesome, resulting in poor deburring efficiency in subsequent work. For this reason, we propose a hot forging equipment for automotive output shafts. Utility Model Content
