Erichsen Cupping Test
This Cupping Test Machine is especially designed for an easy and quick quality conformance inspection and quality control on sheet and strip metal, but also particularly suitable for production monitoring because of its sturdy construction. There are important reasons for using the Cupping Test Machine, Modelfor quality assurance:. The good functional layout of Model makes this machine particularly user friendly.
Operators without previous knowledge or experience can be quickly trained to operate the machine continuously. The sturdy design and the hydraulic oil system employed ensure that minimum wear is experienced so that a good repeatability of the test results is assured over a long period of time.
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 Cupping Test the sheet metal specimen in the form of a strip is inserted in the test cylinder and centralised by locating diagonally.
After pressing the “Start” push button the sheet holder force of 10kN as well as the drawing speed – etichsen 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 ericsen delay the crack detection using a potentiometer. Often this facility is necessary for testing thicken sheet metal panels in order to achieve a uniquely defined crack in conformity with the standards. Request a Quote Request Services.
