A spinning tool for producing a spinning pulley

Abstract

The utility model relates to the production field of pulley, specifically relates to a spinning frock for spinning pulley production, including frock disc, be used for supporting integral device, the lower part fixed connection of frock disc has fixed cylinder, the upper part of frock disc is set up as conical shape, frock subassembly is used for supporting spinning pulley, the frock subassembly includes installation groove, the installation groove is set up in the inner wall of frock disc upper part, the inner wall of installation groove is inserted with auxiliary ring. Through the same angle of the inclined surface of auxiliary ring upper part, with pulley inside conical surface accurate adhesion, form support, and the anti -skid groove of auxiliary ring surface further increase friction, avoid spinning process pulley because high -speed rotation or stress produce slip, ensure the forming accuracy of key parts such as wheel groove, contour, simultaneously, the plug -in of auxiliary ring is inserted with the insertion hole of installation groove through the positioning pin and realizes pre -positioning, and then is locked through fastening bolt, prevents the deviation of auxiliary ring itself.
