Narrow-flow-channel three-dimensional impeller slotting welding method and narrow-flow-channel three-dimensional impeller

Номер: CN116352224A
Принадлежит:

The invention discloses a narrow-runner three-dimensional impeller welding machining method and a narrow-runner three-dimensional impeller, and the narrow-runner three-dimensional impeller welding machining method comprises the steps that a blank is turned to form a wheel disc and a wheel cover; blades are milled on the wheel disc; a welding groove is milled in the wheel cover; and the wheel disc and the wheel cover are welded into a whole in a manual welding mode to form the impeller. Therefore, compared with an electric spark machining technology, the narrow-runner three-dimensional impeller is machined in a manual welding mode, the machining period is short, the machining cost is low, and compared with welding machining of a welding robot, welding conditions and welding parameters can be adjusted in real time according to deformation caused by welding in the welding process so as to meet the requirement of the current welding position; and therefore, the good welding effect is guaranteed ...

Process method for pressing and splicing forming of BCL barrel-shaped machine shell air outlet barrel

Номер: CN116408603A
Принадлежит:

The invention provides a process method for pressing and splicing forming of an air outlet cylinder of a BCL cylindrical shell, which comprises the following steps of: carrying out lofting modeling on an air cylinder flange side by taking a plane circle as a modeling standard and on a shell cylinder side by taking an intersecting circle on a cylinder body as a standard by referring to the design size of the air outlet cylinder by using sheet metal unfolding software; an air outlet cylinder unfolding plane pattern is obtained through the unfolding function of sheet metal unfolding software; carrying out profiling lineation treatment on an unfolded line of a plane circle comprising a low point a of the intersecting circle and a profiling vertical line of cold-state series pressure on the unfolded plane sample; performing profiling by taking an air duct flange side arc and an intersecting line lowest point arc of the plate material of the unfolded plane as a reference and referring to the ...
