ROLLING DICE TO SIMULTANEOUSLY CORRECT A BENDING AND PROCESS A SCREW AND A PRODUCTION METHOD THEREOF BY INTEGRALLY COMBINING A BENDING CORRECTION DICE BODY AND A SCREW DICE BODY

摘要

PURPOSE: A rolling dice and a production method thereof are provided to save the time for setting and installing a dice and to improve the productivity by correcting a bending in a body portion of a screw and processing a spiral portion simultaneously. CONSTITUTION: A thread(101) for correcting a bending is formed in one side of a bending correction dice body(100). A recessed potion is formed in one corner of the bending correction dice body at the same size as a screw dice body(200). The bending correction dice body and the screw dice body are integrally combined by combing the screw dice body with the recessed portion through a combining device.
