摘要： A method for the production of a piston for an internal combustion engine, having a circumferential cooling channel, whereby a blank of a lower piston part is forged, and a blank of an upper piston part is produced, the blanks are pre-machined and joined together to form a piston blank, which is finished to produce a piston. At least one depression or recess is formed into the blank of the lower piston part during the forging process. In the finished piston, the depression forms an opening for a coolant inflow and/or a coolant outflow, or the recess forms an excavation groove for a pin securing ring, respectively.

摘要： A multi-part piston for an internal combustion engine has an upper piston part having a piston crown, and a lower piston part having pin boss supports and pin bosses connected with them. The upper piston part and lower piston part each have an inner and an outer support element, which delimit an outer circumferential cooling channel. The inner support elements delimit a cavity that is open toward the pin bosses, and the cavity is provided with a separate cooling oil collector that has at least one cooling oil opening. In a method for producing a piston, the upper and lower piston parts are manufactured, the cooling oil collector is inserted into one of the upper and lower piston parts in a region of the cavity, and the upper and lower piston parts are connected together at their support elements.

摘要： A method and apparatus for simultaneously producing a first piston part and a second piston part via a forging device may include an upper die, at least one intermediate die, and a lower die. A first billet may be placed between the upper die and the intermediate die, and a second billet may be placed between the intermediate die and the lower die. The upper die and the lower die may be configured to be moved toward each other, whereby the first piston part is forged from the first billet and the second piston part is forged at the same time from the second billet. The upper die and the lower die may then be configured to be moved apart, and the piston parts may be removed.

摘要： A piston for an internal combustion engine has an upper part and a lower part. The upper part has a collar with a ring rib and the lower part has a wall and a contact part radially within the wall. When the upper part is connected with the lower part by friction welding, the face surfaces of the ring rib, the collar, the wall, and the contact part form friction-welding surfaces and form a cooling channel and a cooling cavity between them. To supply the cooling channel and the cooling cavity with cooling oil, radial bores are introduced into the ring rib, which bores connect the cooling channel with the cooling cavity. In this way, it is guaranteed that a sufficient residual amount of oil collects in the cooling channel and in the cooling cavity, which amount is constantly renewed, and leads to good cooling of the piston crown.
摘要翻译：内燃机的活塞具有上部和下部。上部具有带有环形肋的套环，下部具有壁和径向在壁内的接触部分。当上部通过摩擦焊接与下部连接时，环形肋，轴环，壁和接触部分的表面形成摩擦焊接表面，并在它们之间形成冷却通道和冷却腔。为了通过冷却油供应冷却通道和冷却腔，径向孔被引入到环形肋中，该孔将冷却通道与冷却腔连接。以这种方式，可以确保在冷却通道和冷却腔中充分剩余的油量聚集在该冷却槽中，该量不断更新，并且导致活塞冠的良好冷却。
