STD-DN 33 DRAW STRIP TESTER

説明

The STD-DN 33 Draw Strip/Draw Bead Tester comprises a long stroke electro mechanical ball screw actuator mounted horizontally on a steel bed plate in line with a tooling fixture. The actuator has an integral LVDT for displacement measurement and is controlled by means of a standard a.c. vector drive with encoder feedback.

The tooling fixture comprises two articulated arms, each carrying one half of a draw tool. The arms are connected to a fixed point on the machine bed-plate by means of a force transducer, in such a way as to measure the combined drawing force on the arms. The clamping force on the draw tool is by means of a hydraulic cylinder with force transducer feedback and controlled by means of a proportional control valve.

The standard specimen is a long strip of material of up to 25 mm width, which is connected to the actuator by means of standard mechanical grips.
