Method of making mounting method for a metal seat ring which is welded in the assembled carrier hoop in order to form the annular cooling tube of the piston of an internal combustion engine, the fin metal sheet ring and is assembled to the carrier hoop

摘要

Mounting consists of a metal sheet ring, substantially the cross-section is "U"-like, free end of the "U" branch, the inner edge on the annular seat portion formed on the inner surface of the carrier hoop The bound is placed in alignment with the coupling and the support is placed on the body of the carrier hoop and is sealed by an annular weld bead of each extending along the annular seat of the above, a metal seat ring, both cyclic the inner surface is comprised of a molded ring-shaped cooling tube (3) and the inner diametral surface of the carrier hoop extending between the seat and by (7). By generating a circular disc by cutting it by acquiring a flat metal sheet having a desired thickness, and stamping said disc, generates a circumferential wall having an edge bent branch fins, the method configured in the previous step and stamping the circular edge on the opposite side of the edge bending is removed by cutting the circular bottom by stamping a member that is, obtain a ring that is configured in the previous step, already present in the branch fins in the first to form a folded edge of the fin branch of the second by the. Consists of a single piece of sheet metal, and its cross-section having a branched fin corresponding to the pre-built design different sheet metal ring to be obtained, is a "C-" outline.
