Materials Testing Systems 49 The servo actuator, which is integrated in the upper crosshead, has a long piston stroke which makes testing space accessible for easy and effi cient testing of different samples lengths. The long piston stroke meets the extreme requirements of international standards without changing the crosshead position. On piston rod end a anti-rotation system prevents the natural tendency of the actuator to rotate. All Series TTM models are equipped with a high resolution (0.82 μm) digital displacement transducer for accurate and reliable closed loop position of actuator, piston stroke control and measurement. The precision load cell is located between base platen and lower grip, providing high accuracy test after test. The load cell additionally features excellent repeatability, compact design, low temperature drift and accessible mounting. The manifold is attached direct on actuator providing close-coupled servo valve and accumulators for improved performance and reduced pressure fl uctuations. The servo valve features high force level permanent magnet linear force motor directly driving the spool. A LVDT is attached to the spool to provide spool position feedback. An internal loop is closed around the spool position. The valve provides additionally low hysteresis and low threshold, Series TTM 600-3000 kn in 4-Column-Construction low current consumption at and near hydraulic null, standardized spool position monitoring signal with residual ripple, electric null adjust and with loss of supply voltage or broken cable or emergency stop, the spool returns to its spring centred position without passing a load move position.

64 Materials Testing Systems ERICHSEN Cupping Testing Machines Series ECM 60 kn for Sheet Metal For quality monitoring for sheet metal 0.1 up to 3.5 mm thickness. The machine features an electro-hydraulic drive, max. drawing force of 60 kn and an automatic switch off at specimen failure. Standards and Tests The ERICHSEN Cupping Test on all ferrous and non-ferrous metals in accordance with ISO 8490, EN 14-58, EN 14-67, EN ISO 20482, BS 38 55, NF A 03-602, NF A 03-652, ASTM 643-84, JIS Z-7729, UNI 3037, UNE 7080, GOST 10 510, ICONTEC 21, SIS 11 26 35, SABS 0132-197, GB 4156-84. In addition, the Olsen Test as used in the USA can be performed on the testing machine when appropriate tools are set up. The Deep Drawing Cup Test for the determination of the ear forming tendency and maximum drawing ratio according to DIN EN 1669, DIN 50 155, UNI 6124-67, MSZ 5731-68, GB/T 15825, ISO 11531. The Bore Expanding Test in accordance with Siebel and Pomp (KWI), ISO 16630. Test, the round blank manufactured by the electro-hydraulic blanking press, is placed into an infi nitely variable centring device located in the test cylinder. After pre-selection of the sheet holder pressure the blank is drawn by a drawing punch (normally 33 mm dia.) to a cylindrical hollow part, the so-called cup. The inner diameter of the drawing die used, corresponds to the sheet thickness to be tested. After return of the drawing piston to the starting position, the cup can be removed from the test head without any diffi culty. When carrying out the Bore Expanding Test (KWI) the initial bore (in accordance with the dimensions of the tools, i. e. normally 7.5 mm or 12 mm) is applied to the sheet metal specimen by drilling and reaming. Afterwards this initial bore is expanded until a crack appears. Features The machine consists of a sturdy sheet metal housing into which the test aggregate (test cylinder with work piston, sheet holder piston) and the test tools as well as the hydraulic system are integrated. The operator s controls are arranged conveniently on a control panel. As an option, an electro-hydraulic blanking press for the manufacture of blanks for the Deep Drawing Cup Test can be fi tted into the machine housing. When carrying out the ERICHSEN Cupping Test, the sheet metal specimen in the form of strip is inserted into the test cylinder and centralised by locating diagonally. The sheet holder force of 10 kn (in accordance with the standard) is adjusted using a special regulating valve, and the actual cupping process is initiated by selecting the standardised drawing speed on the speed regulator. Since the testing machine is equipped with the function automatic stop at specimen failure the forward speed is automatically stopped when the crack occurs, so that in any case an objective test result is achieved. The ERICHSEN cupping value is displayed with an accuracy of 0.1 mm on the digital counter.
