The application discloses a thin-wall pipe forming die and method, and relates to the technical field of aero-engines. The die comprises an upper die, a lower die and a support. The support and the lower die can move relative to each other to meet different disassembly and assembly requirements. The forming method adopts the process of whole-plate blanking, edge rolling butt welding, segmented and step-by-step stamping, pressure maintaining and shaping and end cutting. The application solves the problems of conventional split splicing welding process, such as many welds, large deformation, poor structural strength and low processing efficiency. The application adopts the mode of segmented stamping forming after whole-plate edge rolling welding, cancels multi-segment split welding, guarantees the integrity of the integrated structure of the gas film plate thin-wall pipe, improves the overall strength, pressure resistance and fatigue resistance of the component, simultaneously simplifies the processing procedure, reduces the production cost, and improves the processing efficiency and the product yield.

This invention discloses an integrated device for automatic ink supply and viscosity control, comprising a housing with a first conical toothed disc inside. The first conical toothed disc is connected to a second conical toothed disc above it via a magnetic coupler. The second conical toothed disc is connected to a drive motor via a first rotating shaft. The bottom of the first conical toothed disc is connected to several stirring shafts via a stirring mechanism. A bevel gear meshes between the first and second conical toothed discs. A second rotating shaft is located at the outer end of the bevel gear, and a second gear is located at the outer end of the second rotating shaft. A locking mechanism is provided between the second rotating shaft and the second gear. An annular toothed disc is sleeved on the first rotating shaft above the second conical toothed disc. The second gear meshes with the annular toothed disc via a transmission gear. An inlet pipe is provided on the housing, and a gate valve is provided on the inlet pipe. The annular toothed disc drives the gate valve to open and close via a transmission mechanism. This solution can achieve automatic ink dilution.
