Qualitest’s Sheet Metal Testing Machine, Model 102, with electro-hydraulic drive, max. drawing force of 60kN and automatic switch off at specimen failure.
This Sheet Metal Testing Machine is intended for testing materials in the medium thickness range (0.1 to approx. 3.5mm). It provides rapid a reliable quality monitoring for sheet metal producers and users.
Model 102 is suitable for:
DIN EN ISO 20482 |
JIS Z-2247 |
JIS Z-7729 |
ASTM 643-84 |
NF A 03-602 |
NF A 03-652 |
UNE 7080 |
GOST 10 510 |
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.
In accordance with Siebel and Pomp (KWI), depending of the testing method the following sheet metal thicknesses can be tested:
The above mentioned maximum sheet thicknesses are based on material with a tensile strength of 400 N/mm².
There are important reasons for using the Sheet Metal Testing Machine, Model 102, for quality assurance:
Quantitative measurement of sheet quality by means of the Cupping Test provides a basis of communication between sheet metal producers and users. The form of the crack and the surface roughness (= grain size) also provide information on the quality of the sheet metal and is suitability for drawing, giving valuable information especially to the sheet metal producer.
The good functional layout of Model 102 makes this machine particularly user friendly. All relevant test tools can be set up in the test cylinder quickly and without difficulty. The sturdy design and the hydraulic system employed ensure that minimum wear is experienced so that accurate test results are assured over a long period of time.
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.
When carrying out the 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 e.g. 10kN in accordance with DIN EN ISO 20482 is adjusted using a special regulating valve, and the actual cupping process is initiated by selecting the from the test specification required 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 cupping value is displayed with an accuracy of 0.1mm on the digital counter.
When carrying out the Bore Expanding Test (KWI) the initial bore (in accordance with the dimensions of the tools, i.e. normally 7.5mm or 12mm) is applied to the sheet metal specimen by drilling and reaming. Afterwards this initial bore is expanded until a crack appears.
The various accessories make this sheet metal testing machine particularly versatile. For further detailed specifications please see our Price List below.
Data logger for recording the measurements such as drawing and blank holder force and stroke by time; the connection is made by a USB connection to an external PC (included in the Data logger software scope of supply). The included software runs under WIN 2000/XP. The system consisting of measuring transducer for drawing force and analogue output for the stroke as well as the corresponding interfaces, A/D converter module.
The Cupping Test (in accordance with DIN EN ISO 20482, and corresponding to national and international standards) is a test providing simple and quick means of assessing the multi-axis ductility of sheet and strip using a procedure that relates closely to practical processes. The depth range reached at failure is, however, only an initial guide to the evaluation of the forming properties of the sheet metal.
The software enables the continuous acquisition of measured values with simultaneous display of the force/displacement diagram throughout the forming process. The data record is terminated by reaching the maximum pulling force.
This data is presented immediately on the VDU on completion of the test alongside the graph of the force against displacement.
Either a printout can then be obtained and the data saved or the data can be easily transferred to other evaluation programmes (e.g. Microsoft Excel). The scope of supply includes PC, VDU and printer.
