Description

Technical Field

[0001] The utility model belongs to the technical field of forging processing of rear axle gears of new energy trucks, and specifically relates to a forging press for rear axle gear blanks of new energy trucks. Background Art

[0002] The rear axle gear of a new energy truck is responsible for transmitting the power of the electric motor to the wheels, enabling the truck to move. During production, the rear axle gear needs to be forged using a forging press. The strong pressure of the forging press acts on the metal raw material, causing it to undergo plastic deformation in the mold, thereby obtaining a gear blank of the required shape and size.

[0003] Currently, after the raw materials are forged into gear blanks by a forging press, manual material removal is often required. Since the metal raw materials undergo plastic deformation in the mold, they will fit tightly with the molding cavity of the mold. Therefore, when manually removing the materials, tools are needed to remove the gear blank from the molding cavity. The operation is relatively troublesome and the temperature of the gear blank that has just been forged is high. The operator is prone to the risk of being burned when removing the materials, which greatly affects the overall production efficiency. Utility Model Content
