Embodiment Construction

[0080] The technical solutions of the present invention will be further described below with reference to the accompanying drawings.

[0081] A sealing ring forming die device for an engine, comprising an initial forming die and a final forming die,

[0082] Among them, the initial forming mold, such as figure 1 shown, including:

[0083] A pressure plate 1 (such as figure 2 , 3 ), which is a disc with a round hole in it, which is fixed with the first upper die by six bolts.

[0084] A first upper die 2 (such as Figure 4 , 5 , 6), is a ring, the lower end of the ring has four spring grooves for installing the spring, and there is a circle of flash near the lower end, and there are 4 holes with a diameter of 16mm on the flash.

[0085] A first lower die 3 (such as Figure 7 , 8 , 9), the shape is similar to the first upper die, it is a ring, the upper end of the ring is provided with four spring grooves for installing springs, and there is a circle of flash near the u...

Abstract

The invention relates to a forming die device for a sealing ring used in an engine. The device comprises a primary forming die and a final forming die, wherein the primary forming die specifically comprises a pressure plate, a first upper die, a first lower die, a supporting spring, an oil baffle pan, a base, an internal mold column, a sealing end cover, an oil guide pipe adapter, and the like; and the final forming die specifically comprises a pressure plate, a second upper die, an upper locking lantern ring, a lower locking lantern ring, a second lower die, an oil baffle pan, an intermediate model, a base, an internal mold column, a sealing end cover, and the like. The forming method for the sealing ring used in the engine comprises the following two steps of primary forming and final forming.

Description

technical field [0001] The invention relates to a molding method and a mold device for a sealing ring used in an engine, in particular to a molding method and a mold device for an omega ring used in an aero-engine, which are suitable for the production process of a ring seal ring with complex section. Background technique [0002] The complex tiny Ω ring is mainly used in the sealing of aero-engines. This part has remarkable characteristics such as high material strength, complex cross-sectional shape, small feature size and large relative size, which are difficult to achieve by traditional processing methods. At present, there is no domestic production capacity, and it mainly relies on imports from abroad. The price of each piece is tens of thousands of dollars, which is quite expensive. Therefore, it is imperative to study a set of manufacturing processes suitable for such parts. [0003] The basic dimensions of the parts are figure 1 Shown: One of the typical parts is ...
