CONTROLLER FOR WORK RIVET PRESS-FITTING MACHINE

摘要

04269-51 RDF:jy A controller for a work rivet press-fitting machine has a main hydraulic cylinder for press forming connected with a hydraulic power source and having a piston shaft. The hydraulic cylinder is adapted to extend and retract to press-fit the heads of work rivets in rivet holes formed in a product sheet. The controller includes a linear encoder for detecting the axial position of the piston shaft; an electric/hydraulic servo valve in a hydraulic circuit between the hydraulic power source and the hydraulic cylinder; a machining data setting means for setting machining data for the work rivet; and a control unit receiving the output of the linear encoder and the machining data to perform operations and controlling the hydraulic cylinder by controlling the electric/hydraulic servo valve based on the results of these operations.
