This invention discloses a GH4169 alloy extra-large turbine disk skin structure and its design method, belonging to the field of metal material forming. The skin structure, with its forging surface radially along the center hole of the rough-machined turbine disk delivery part, includes a skin center section, a second transition section, and a first transition section connected sequentially from the inside to the outside. Both the first and second transition sections are conical surfaces, with rounded corners at their intersection. The angle between the generatrix of the first transition section and the vertical direction is θ1, and the angle between the generatrix of the second transition section and the vertical direction is θ2, where θ1 > θ2. The two-stage transition section design of the forging surface of the skin structure effectively disperses stress concentration in the central area of ​​the die during forging, significantly reducing local stress at the contact point between the die punch and the blank. The stress value can be controlled below 320 MPa, avoiding punch deformation or damage; reducing fatigue damage to the die under high stress, extending die service life, and reducing production costs.

The invention discloses a multi-path inlet and outlet booster pump, which belongs to the field of supercharging devices, and comprises a first cavity, a second cavity, a first oil inlet passage, a first oil outlet passage and at least two oil guide passages positioned between an end cover and a reversing valve body, one end of an oil guide passage is connected with the second cavity, and the other end is connected with hydraulic oil outside the booster pump; one end of the other oil guide passage is connected with the first cavity, and the other end is connected with hydraulic oil outside the booster pump; when the pressurizing piston reverses, external hydraulic oil smoothly enters and exits the pressurizing cavity under the common buffering effect of the at least two oil guiding channels. The at least two oil guide channels located between the end cover and the reversing valve body are arranged to provide oil storage, oil inlet and outlet oil path buffering generated during reversing of the pressurizing piston is provided for hydraulic oil in the first cavity and the second cavity, and sudden pressure change at the moment of oil inlet and oil outlet is avoided; and oil storage and pressure balance on the oil inlet side and the oil outlet side are achieved.
