Abstract

PURPOSE:To obtain a portable press working machine of simple structure that can work metals with strong pressing force by constituting the machine of a base stand on which a die incorporated in a die set is placed and a cross beam that supports the output cylinder of a hydraulic device in the upper part of the die. CONSTITUTION:A necessary die 3 is set to a press working machine 1 and an output cylinder 22 is so moved together with a saddle that an output shaft 26 comes to the center of the die 3 and fixed with a bolt 95. specified pressure and amount of advance are given to the output shaft 26 of the cylinder 22 by treading the driving tool of a pressure oil feeding device 21. The punch holder 31 of a die set 30 is pushed in by the output shaft 26, and a sash member S inserted between a set of punch 32 and die 33 is cut to desired shape and size. After cutting, the output shaft is pulled up by operating a releasing tool 25 made up of a pedal. Similar operation is repeated using other punch 32 and die 33 to complete the cutting work.
