The Model 142 series of Universal Sheet Metal Testing Machines are equipped with an electrohydraulic drive, fully automatic test sequence and switch off at specimen failure, max. drawing forces 200 kN or 400 kN – Capable of performing ERICHSEN Cupping Test, ERICHSEN Deep Drawing Cup Test, FLC-Test, Bulge-Test, High Speed Test including an extensive range available on request. Testing in acc. ISO 8490, EN 14-58, EN 14-67, EN ISO 20482, JIS Z-2247, DIN EN 1669, ISO 11 531, JIS Z 2249, GB/T 15825
Application: This Testing Machine can be used not only to perform effortlessly, quickly and accurately all important and known deep drawing tests for ferrous and non-ferrous metals, but it is also designed for a large number of additional technological investigations like the ERICHSEN Cupping Test and the ERICHSEN Deep Drawing Cup Test on sheet and strip.
Relevant attributes are: Square Cup Test (40 x 40 mm), Bore Expanding Test (KWI Test), Deep Drawing Test with Blankholder Quick Release (for Earing Test), Deep Drawing Test with Preselected Punch Stroke, Deep Drawing Test at High Temperatures up to 550 °C, Bulge Test, ERICHSEN Cupping Test for Lacquer and Paint in accordance with DIN ISO 1520, Stamping Lacquer Test and Deep Drawing Cup Test on Coil Coatings.
Special Requirements on request.
The Testing Machine is driven electro-hydraulically. The test sequence can be controlled automatically or manually, as desired. A programme logic control is used to control the functions of the machine. Drawing force and blankholder force as well as the drawing punch stroke are displayed digitally. The triple-acting hydraulic system in conjunction with the general design results in the following cost saving simplifications:
- Blanking press in the test head
- Hydraulic cup ejector
- Fully-automatic test sequence
The Sheet Metal Testing Machine, Model 142, was developed not only for testing as a means for continuous production control, using standardised and other established methods, but also for research into all aspects of testing of sheet metal for deep drawing by studying all that is relevant to sheet metal forming.
