Circular steel transcription machine and circular steel transcription manner

摘要

PURPOSE:To arbitrarily set the position and the depth of a gravure image to be transferred to a circular steel by providing a hydraulic motor for pressing the circular steel on an original late by driving a pressure saddle downward, measuring means for measuring the transfer depth of the steel by the saddle, and numerical controller for controlling the drive of the saddle and the movement of a table. CONSTITUTION:A predetermined instruction value is input to an NC device to control and drive a servo value or a proportional control valve and a hydraulic motor 3 to reduce a pressure saddle 7 by a predetermined pressure force to press a circular steel 31 to an original plate. A table 60 is reciprocated desired times in this state to transfer an image from the original plate to the steel 31. In this case, since a supporting shaft 32 is rolled on the lower end face 35a of a guide plate 35, an overload is no applied to the shaft 32. When the pressure force of the steel 31 and the reciprocating distance of the table 60 are suitably controlled in response to the downward moving distance of the saddle 7 measured by a scale A, the recess of desired depth can be accurately formed on the steel 31.
