Forming device for thin-wall special-shaped seal rings of engines

Abstract

The invention relates to a forming device for thin-wall special-shaped seal rings of engines. The forming device is characterized by comprising an upper movable die (14), a lower fixed die (15), a front movable die (19) and a rear movable die (17); the lower fixed die (15) is fixed into a die closing forming region and is of a disc-shaped structure, a lower fixed die cavity with an upward opening is arranged at the outer edge of the lower fixed die (15), the upper movable die (14) is of a disc-shaped structure, an upper movable die cavity with a downward opening is arranged at the outer edge of the upper movable die (14), the upper movable die (14) is positioned right above the lower fixed die (15), and the front movable die (19) and the rear movable die (17) are respectively positioned on a front section and a rear section of the die closing forming region. The forming device for the thin-wall special-shaped seal rings of the engines has the advantages that the seal rings with thin-wall and special-shaped characteristics can be effectively produced by the forming device, and the forming device is high in yield and low in production cost.

Description

technical field [0001] The invention relates to a thin-wall special-shaped sealing ring forming device for an engine, which belongs to the field of stamping manufacturing. Background technique [0002] The engine thin-wall special-shaped sealing ring, also known as the engine sealing ring, is a static sealing structure with a new type of sealing form and better sealing effect installed inside the aero-engine. The airway of the engine is sealed at the end face, and its cross section is generally "W", "M" or more complicated wave shape, which has better elasticity than the simple C / U ring, and has been widely recognized at home and abroad in recent years and research, but this type of component has the characteristics of thin wall (generally 0.2mm to 0.3mm), large deformation and high precision. Production costs are high. Therefore, it is particularly important to seek a thin-wall special-shaped sealing ring forming device capable of effectively producing thin-wall special-s...
