Hydraulic system for automatic oil press

摘要

PURPOSE: A hydraulic system for an automatic oil press is provided to control the insertion amount of operational oil flowing into a hydraulic cylinder, and the oil pressure. CONSTITUTION: A hydraulic system for an automatic oil press comprises the following: a hydraulic pump(100) operating an ascending/descending process of a main cylinder; a socket unit transferring powder to a motor using a pulley(111); a power transmission shaft(110) with an eccentric unit formed on the central circumference surface for being coupled with a second bearing; a rotation hole for inserting the power transmission shaft; a housing(120) including first bearings formed on the upper and lower sides of the inner circumference of the system; a hydraulic cylinder(131) for inserting a piston with one end protruded to the inner circumference of an insertion hole; first and second discharge holes(135,136); and an influx path including a second step hole.
