MEASURING APPARATUS FOR DRAWBEAD OPENING FORCE

摘要

The present invention relates to a draw bead opening force measuring device, the fixed mold and the beads are formed can bead cancer The die part and provided with a moving mold formed, and the load cell is installed on the rear surface of the moving mold, and pressing means to provide a pressing force, and the load cell is composed of an elastic member interposed between the pressing means, the fixed mold and moving and holding the pressing portion to provide a clamp pressure in the measurement target sample injected between the mold, the take-out section to the sample in the mold upper portion, and the load cell force output of the measurement data for calculating the opening force from the opening portion Drawbead characterized in that it comprises. Drawbead opening force measuring device according to the invention has the advantage of being able to ensure a precise data for the draw bead force by measuring the force with Drawbead opening Drawbead withdrawal force. ;
