摘要:
A method for producing an aluminum piston for an internal combustion engine, which piston is designed as a round skirt piston. In the region of the radially outer end faces of the piston pin bosses the piston skirt has skirt recesses extending in the direction of the piston axis. In order to be able, when using the piston, to produce skirt recesses that have any shape a piston blank is produced in a forging process using a forging die, which piston blank has inner faces that are complementary to the outer shape of the piston having skirt recesses and not-recessed regions of the piston skirt, and the piston blank can then be further machined to produce the aluminum piston.
摘要(中):
一种用于制造用于内燃机的铝活塞的方法,该活塞被设计为圆裙活塞。 在活塞销的径向外端面的区域中,活塞裙部具有沿活塞轴线方向延伸的裙部凹口。 为了能够在使用活塞时制造具有任何形状的裙部凹部,在使用锻造模具的锻造工艺中产生活塞坯料,该活塞坯件具有与活塞的外部形状互补的内表面, 裙部凹部和活塞裙部的非凹陷区域,然后可以进一步加工活塞坯料以产生铝活塞。
