Equipped With:
This testing machine is available as a work-top model with compact dimensions which requires only a minimum of space. All hydraulic and electronic control and drive units are enclosed in a sturdy sheet metal housing. The necessary control elements are clearly laid out on the front panel. The test cylinder is installed at an angle, so that the test procedure can be carried out comfortably when seated. It is no longer necessary to open the test head to remove the specimen, as this is automatically released by the hydraulic specimen holder once the test has been conducted. The entire test procedure runs automatically, including crack detection. When carrying out the ERICHSEN Cupping Test the sheet metal specimen in the form of a strip is inserted in the test cylinder and centralized by locating diagonally. After pressing the "Start" push button the sheet holder force of 10 kN as well as the drawing speed - both conforming to the standards - are adjusted automatically and the test procedure is initiated. As the testing machine is equipped with the function "automatic stop at specimen failure" the cupping procedure is automatically interrupted when a crack appears so that an objective test result will always be achieved. It is possible to delay the crack detection using a potentiometer. Often this facility is necessary for testing thick sheet metal panels in order to achieve a uniquely defined crack in conformity with the standards.
