Manufacture of scroll for scroll compressor

Abstract

Abstract PURPOSE: To manufacture scrolls of high accuracy with less man-hour for processing than before by fixedly placing a scroll-shaped strip by bending and other processes on a flat plate by means of a positioning jig, and uniting them as they are. CONSTITUTION: On a flat plate electrode 8 provided with projections 9 to be fitted to holes 5 on a flange 1C, a flange 1C and a lap 2A which is shaped into a scroll by bending a polished-steel strip of a required length and width and fitted in a jig 6 are placed. Meanwhile, another roller electrode 10 is arranged on the upper edge of the lap 2A to be rolled on in order. Since a fixed amount of current is given between the roller electrode 10 and the flat plate electrode 8, the lap 2A and the flange 1A are united with each other. In this method, a scroll-shaped strip by bending and a separately-manufactured flange are united in layers for mass-producing scrolls of high accuracy in a low cost. COPYRIGHT: (C)1981,JPO&Japio
