The testing machine, Erichsen cupping test ericsen, is suitable: Determining the most appropriate sheet thickness for a particular drawn workpiece to optimise the ratio of price to suitability for the manufacturing process. For more information, visit the cookies page.
Erichsen Cupping Test
A method of localized necking detection based on the phenomenon of laser speckle was developed. This Cupping Test Machine is especially designed for an easy and quick quality conformance inspection and quality control on sheet and strip metal, ericnsen also particularly suitable erichsen cupping test production monitoring because of its sturdy construction.
Testt 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.
Author links open overlay panel A. After pressing the “Start” push button the sheet holder force of 10kN as well as the drawing speed – both conforming to the standards – are adjusted automatically and the test erichsen cupping test is initiated.
Cookies erichsen cupping test used by this site.
Often this facility is necessary for testing thicken sheet metal panels in order erichsen cupping test achieve a uniquely defined crack in conformity with the standards. Published by Elsevier Sp.
Test Tools for ERICHSEN Cupping Test on Strip and Sheet Metal — ERICHSEN
All hydraulic and electronic control and drive units are enclosed in a sturdy sheet metal housing. Recommended articles Citing articles 0.
Without special test preparation it is immediately possible to establish if the material supplied has the prescribed drawing quality. Erichsen cupping test cupping test has usually been used to determine the height of the cup at the moment of sheet metal fracture, defined as the Erichsen Number Text.
Operators without previous knowledge or experience can be quickly erichsen cupping test to operate the machine continuously. There are important reasons for using the Cupping Test Machine, Modelfor quality assurance:. The test cylinder is installed at an angle, so that the test procedure can be carried out comfortably when seated.
Parameter LN-IE can be helpful in formability comparison of different grades of sheet metals. Abstract Erichsen cupping test has usually been used to determine the height of the cup at the moment of sheet metal fracture, defined as the Erichsen Number IE. The paper presents a proposal of using Erichsen cupping test to determine the additional parameter — the height of the cup LN-IE at the moment of localized necking in trst metal, which usually precedes fracture of erichsen cupping test metal.
The entire test procedure runs automatically, erichsen cupping test crack detection. Erichsen cupping test necessary control elements are clearly laid out on the front panel.
Sorting out of material of lower quality arriving at the Goods Inwards Department. 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 erichsen cupping test over a long period etst time. It is possible to delay the crack detection using a potentiometer. Sheet Metal Formability – Ductility Testers. The good functional layout of Model makes this machine particularly user friendly.
