Description

Technical Field

[0001] The utility model relates to the technical field of gear forging, in particular to a gear forging die for preventing flash. Background Technique

[0002] Gear forging is a process for manufacturing gears, usually referring to the use of forging methods to make gears. Forging is a processing method that makes metal materials undergo plastic deformation by applying pressure to obtain workpieces with predetermined shapes and sizes. Compared with machining, forging can make better use of materials, improve the mechanical properties of materials, and has lower costs. Gear forging is mainly used for producing a large number of gears, especially in the fields of automobiles, aerospace, and construction machinery. Since forging can produce metal structures with high strength and toughness, forged gears are usually used in occasions that need to bear heavy loads and impact loads.

[0003] During the forging process of gears, the metal blank is extruded from the gap of the die under pressure to form excess metal flash. These flashes usually appear at the opening of the die. They are not part of the design and need to be removed. The existence of flash will affect the appearance and dimensional accuracy of the gear, and may also cause problems during the assembly process of the gear. Currently, when grinding the gear flash, it is necessary to wait for the gear forging to cool down, take out the gear, put it into the grinding equipment, and grind the gear flash. The operation is rather troublesome and the flash cannot be processed simultaneously when the forging is completed, resulting in a reduction in work efficiency. Content of the Utility Model
