Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of assembly tooling of special-shaped parts, and particularly relates to a special-shaped part hoisting device and a use method thereof. BACKGROUND

[0002] Special-shaped parts (referred to as special-shaped parts) refer to irregular, non-standardized mechanical parts. Special-shaped parts refer to mechanical elements that are significantly different from common standardized parts in shape and need to be specially designed according to the use scenario.

[0003] Special-shaped parts can be divided into the following types according to manufacturing processes:

[0004] 1. Casting special-shaped parts: formed by injecting molten metal into a mold, suitable for complex structures such as engine blocks, with the advantage of high surface finish.

[0005] 2. Forging special-shaped parts: plastic deformation through hot pressing or cold forging process, commonly used for parts that require high strength and fatigue resistance such as gears and transmission shafts.

[0006] 3. Stamping special-shaped parts: using a mold to press-form metal sheets, suitable for thin-walled parts such as electronic device housings and heat sinks.

[0007] The technical characteristics of special-shaped parts include:

[0008] 1. High geometric complexity: may contain curved surfaces, non-symmetrical hollow or multi-layer nested structures (such as turbine blade air film cooling holes).

[0009] 2. Strict tolerance requirements: for example, the hole diameter tolerance of an aviation hydraulic valve body needs to be controlled within ±0.005 millimeters to ensure sealing (refer to ISO 2768 precision level standard).

[0010] 3. Functional priority: design needs to consider weight reduction (such as aircraft titanium honeycomb structure), wear resistance (such as hard alloy coating on mine mechanical pick teeth) and other goals.

[0011] 4. Special production equipment: five-axis linkage CNC machine tools, electric spark wire cutting equipment, etc. are needed to complete complex curved surface machining.

[0012] Although special-shaped parts have design and manufacturing difficulties, their performance advantages brought by special structures make them an indispensable part of high-end equipment manufacturing.
