INSTALLATION FOR WELDING ON INNER CYLINDRICAL SURFACES OF PARTS BY CENTRIFUGAL CASTING

摘要

foundry, namely equipment for restoring worn inner cylindrical surfaces of parts. SUBSTANCE: installation includes ingot mold driven to rotation by means of electric motor, mechanism for centering part on prism; mechanism for feeding and locking part in ingot mold; apparatus for heating part and mechanism for pulling restored part out of ingot mold. Apparatus for heating part includes magnetic starters arranged at both sides of part. Contact discs of starters are arranged normally relative to axis of ingot mold on core of magnetic winding placed with inclination relative to ends of heated part. Upper point of prism is placed no higher than lower level of restored part; length of prism is less than that of restored part. At heating it is not necessary to rotate prism together with part. EFFECT: simplified design, enhanced operational reliability of installation. 2 dwg
