| 摘要 | PURPOSE: To enhance the size accuracy of cross-sectional contour of a spiral extruded part to facilitate finishing machining by brazing a lapping raw material obtained by cutting off the spiral extruded part and an end plate raw material formed by forging,etc., with each other, thereafter machining and finishing the brazed part. CONSTITUTION: In manufacturing a scroll member, an aluminum alloy billet is extruded with high accuracy by continuous extrusion molding to form a long extruded part 1. The extruded part 1 is cut off at specified intervals in the axial direction, that is, at equal intervals slightly greater than the height specified to a lap O2 mounted in an upright position on one side of an end plate O1, at right angles to its axis to form a lapping raw material 2. On the other hand, an aluminum alloy disc material is forged to form an end plate raw material 3. A brazing filler metal-foil 4 is then placed on the joint surface of the end plate raw material 3, the lapping raw material 2 is loaded on the foil, and thus they are joined together by brazing. After that, the joined raw materials are machined to be finished so as to complete a scroll member. COPYRIGHT: (C)1991,JPO&Japio |
