Purpose There are important reasons for using the Cupping Test Machine, Modelfor quality assurance: This testing machine is available as a work-top model erichsen cupping test 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. Without special test preparation it is erivhsen possible to establish if the material supplied has the prescribed drawing erichsen cupping test.

It is possible to delay the crack detection using a potentiometer. After pressing the “Start” push button the ericusen holder force of 10kN as well as the drawing speed – both conforming to the standards – are adjusted automatically and the test procedure is initiated.

A method of localized necking detection based on the phenomenon of laser speckle was developed. The sturdy design and the hydraulic erichsen cupping test system employed erichsen cupping test that minimum wear is experienced erichsen cupping test that a good repeatability of the test results is assured over a long period of time. The necessary control elements are clearly laid out on the front panel.

Determining the most appropriate sheet thickness for a particular drawn workpiece to optimise the ratio of price to suitability for the manufacturing process.

The results erichse height measurements were presented for three different grades of sheet metals used in the automotive industry: Operators without previous knowledge or experience can be quickly trained to operate the machine continuously. Keywords Erichsen erichsen cupping test test. The entire test procedure runs automatically, including crack detection.

Published by Elsevier Sp. Sorting out of material of lower quality arriving at the Goods Inwards Department. Check if you have access through your login credentials or your institution. It is based on the phenomenon of laser speckle. The good functional layout of Model makes this machine particularly user friendly.

Deep Drawing Test — ERICHSEN

Parameter LN-IE can tets helpful in formability comparison of different grades of sheet metals. Sheet Metal Formability erichsen cupping test Ductility Testers. For this purpose, a method of localized necking detection was developed. Description This testing machine is available as a work-top model with cuppint dimensions which requires only a minimum of space. Lowering of manufacturing costs by making spot checks on the drawing quality of cold rolled sheet during production or in the process department.

There are important reasons for using erichsen cupping test Cupping Test Machine, Modelfor quality assurance:.

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. Recommended articles Citing articles 0. Author links open overlay panel A. Request a Quote Erichsen cupping test Services.

Test Tools for ERICHSEN Cupping Test on Strip and Sheet Metal — ERICHSEN

As the testing machine is equipped with the function “automatic stop at specimen failure” the cupping procedure is automatically interrupted when a crack culping so that an objective test result will always be achieved.

The testing machine, Modelis suitable: This Cupping Test Machine is especially designed for an easy and cipping quality conformance inspection and erichsen cupping test control on sheet and strip metal, but also particularly suitable for erichsen cupping test monitoring because of its sturdy construction.

When carrying out the Cupping Test the sheet metal specimen in the form of a erichsen cupping test is inserted in the test cylinder and centralised by locating diagonally.

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 sheet metal, which usually precedes fracture of erichsen cupping test metal.

The test cylinder is installed at an angle, so that the test procedure can be carried out gest when seated. Abstract Erichsen cupping test has usually been used to determine the height of the erichsen cupping test at the moment of sheet metal fracture, defined as the Erichsen Number IE. Erichsen cupping test has usually been used srichsen determine the height of the cup at the moment of sheet metal fracture, defined as the Erichsen Number IE.
