Japan, July 14 -- HODEN SEIMITSU KAKO KENKYUSHO LTD has got intellectual property rights for 'MANUFACTURING METHOD OF INTEGRATED IMPELLER AND INTEGRATED IMPELLER.' Other related details are as follows:
Application Number: JP,2022-127745
Category (FI): B23H9/10,F04D29/28@R,B23H1/10@Z
Stage: PROBLEM TO BE SOLVED: To provide a manufacturing method of an integrated impeller which enables highly accurate processing while reducing the number of processing steps, the processing time, and costs, and to provide the integrated impeller.SOLUTION: An integrated impeller 100 includes: a first shroud 101 forming a bottom part; a second shroud 102 forming a lid part; a cylindrical hub 103 formed at a center portion of the first shroud; and blades 104 formed between the first shroud and the second shroud and configured to divide a passage 110 in which a fluid flows from an inlet 111 at the inner periphery side where the hub is formed to an outlet 112 at the outer periphery side. In a manufacturing method of the integrated impeller 100, a step for forming the passages of the impeller includes an inner periphery side passage processing step in which an inner periphery side passage processing electrode 30 having a base part 31 attached to a processing machine through a holder, a rod-like part protruding from the base part, and a bending part bending from the rod-like part is inserted from the inner periphery side inlet and rotated around a predetermined position to process the inner periphery side of the passages between the blades.SELECTED DRAWING: Figure 15 (Grant)
