Title:
MACHINING PROCESS FOR LARGE-DIAMETER THIN-WALLED PART
Document Type and Number:
WIPO Patent Application WO/2020/253818
Kind Code:
A1
Abstract:
A machining process for a large-diameter thin-walled part. The machining process comprises the steps of: S1. selecting a raw material having an appropriate size; S2, machining an inner hole (5); S3. performing shaping; S4. performing aging heat treatment; S5. semi-finishing the inner hole (5) and part of the shape; S6. semi-finishing part of the shape; S7. performing natural aging treatment; S8. finishing the inner hole (5) and a second end (8); S9. finishing a second outer circle (2) and a process step (6); S10. finishing a first outer circle (1); S11. machining and forming a flange (3); and S12. machining and forming multiple protrusions (4). According to the machining process, a stable process route is designed to control deformation, reduce the number of times of positioning and clamping, shorten the machining time, improve machining efficiency and ensure product quality; the one-time machining of all features is implemented by means of the positioning of the inner hole (5), ensuring that product deformation is within a controllable range; reasonable process parameters are used to achieve accurate production guidance work, get rid of the limitation of special person and special machine, and well implement automated production.
