Measure roll control method for Coyle material using major roll device and major roll device

摘要

Problem to be solved: to accurately measure the feed dimension of the Coyle material, and to reduce the waste of the Coyle material by the feed size control of the high accuracy, and to make the yield to be able to be supplied to the metal mold by the set feed size in the constant size feed in the head out work, and to improve the yield. Problem to be solved: to provide a major roll device capable of preventing die breakage due to a set due to an insufficient feed dimension and a shortage in feed size of Coyle material.SolutionA major roll device 1 for controlling the size of the forward feed so as not to cause feed size failure;Coyle feed dimension measuring means 2 andDimension setting means 3 for setting Coyle feed dimensionsThe stop means 4 for stopping the Coyle feed when it reaches the set positive feed size andRadial pressPositiveThe major roll device 1 is characterized in that the releasing means 5 is provided with the releasing means 5 to release the stopping means 4.Diagram
