Electro-hydraulic high-speed universal sheet metal testing machine (600/1000 kN) – Model 146 – ERICHSEN

The Model 146-60 is capable of performing a variety of tests on both ferrous and non-ferrous metals. These tests include the ERICHSEN Cupping Test, Deep Drawing Cup Test, Square Cup Test, Bore Expanding Test (ISO 16630), Forming Limit Curves (FLC) determination, LDH Test, and Bulge Test (ISO 16808), among others. This versatility makes it suitable for a wide range of technological investigations in material testing laboratories.

This machine is distinguished by its exceptional drawing speed of up to 3000 mm/min, supported by an innovative separate oil circuit with high volumetric displacement for consistent drawing speeds. Additionally, its electro-hydraulic drive, the option for PC control or manual operation, triple-acting hydraulic system, blanking press in the test head, hydraulic cup ejector, and fully-automatic test sequence are key features that promote efficiency and safety in testing operations.

Yes, the Model 146-60 is adaptable to special requirements, ensuring its capacity to meet diverse testing needs. Its design allows for quick changes of drawing and blanking tools, adding to its versatility and making it an ideal choice for professional laboratories with varying testing requirements.

The machine features an electro-hydraulic drive, and a variety of tests can be conducted including Erichsen cupping and deep draw tests among others. It has a maximum drawing force of 600 kN and a blanking force of 800 kN. The machine offers a drawing speed of up to 3000 mm/min, can accommodate blank diameters up to 220 mm, and requires a power input of 55 kW. The dimensions are approximately 2400 x 1540 x 1500 mm (WxDxH), and it has a net weight of about 3100 kg.

The Model 146-60 requires a power input of 55 kW and operates on a 400 V / 3⏀, 50/60 Hz mains supply. Other voltages can be accommodated upon request, making it adaptable to various international standards and facilities' power supplies.

Safety and efficiency are enhanced through features such as the triple-acting hydraulic system, blanking press in the test head, hydraulic cup ejector, and the option for a fully-automatic test sequence. These features not only improve the reliability of test outcomes but also streamline operations, reduce manual intervention, and mitigate safety risks, providing a safer and more efficient testing environment.

The separate oil circuit with high volumetric displacement is a key innovation that ensures a consistent drawing speed of up to 3000 mm/min across a 150 mm displacement. This system sets the Model 146-60 apart from models relying on nitrogen accumulators, providing steadier and more reliable performance for precise testing outcomes.
