The invention discloses a closed forming method for a thin-walled cylindrical part, belongs to the technical field of metal plastic precision forming, and adopts a composite precision forming technology based on a double-action extrusion technology and a controllable shunting technology to realize non-flash closed precision forming of thin-walled cylindrical parts such as forged steel piston skirts. According to the closed forming method for the thin-walled cylindrical part, no flash is generated, the raw material utilization rate is high, the product size precision is high, the machining allowance is small, meanwhile, in the forging process, openings of the thin-walled cylindrical parts such as forged steel piston skirts face upwards, and automatic production is conveniently achieved. The invention discloses a closed forming system for the thin-walled cylindrical part. The closed forming system can be used for carrying out the closed forming method for the thin-walled cylindrical part.
Description
technical field [0001] The invention belongs to the technical field of metal plastic precision forming, and in particular relates to a closed forming method and a forming system of a thin-walled cylindrical part. Background technique [0002] With the continuous improvement of energy saving and emission reduction requirements, the strengthening index and emission standard of the engine are constantly improving, and the piston is the core component that affects the performance of the engine. The aluminum alloy pistons of diesel engines and gas engines have been gradually replaced by forged steel pistons. Compared with traditional aluminum alloy pistons, forged steel pistons have the following three advantages: [0003] 1. The strength of steel is much higher than that of aluminum. Under the condition of meeting the same use requirements, the height of the forged steel piston can be reduced, and the wall thickness can be reduced, which can reduce the weight of the engine, save...
