Electro-hydraulic cupping and deep-drawing testing machine (120 kN) – Model 134 - ERICHSEN

Introducing the Erichsen Sheet Metal Testing Machine, Model 134, a state-of-the-art solution designed for high-precision evaluation of metal formability. Engineered with an electro-hydraulic drive system, this advanced machinery offers a maximum drawing force of 120 kN, coupled with a uniquely adjustable blank holder pressure of up to 45 kN. Integration of a high-capacity blanking head, capable of exerting a force up to 200 kN, ensures comprehensive testing capabilities across a wide range of metal sheets.

Key Applications and Advantages

Specially developed for both quality assurance and research, the Model 134 excels in delivering swift, accurate assessments of deep drawing tests for ferrous and non-ferrous metals. It’s ideally suited for evaluating cold rolled sheet quality directly on the production floor or within the process department, allowing for the immediate identification of materials that do not meet quality standards. Furthermore, its versatile design enables the execution of the Olsen Test, thereby broadening its applicability in international markets.

Technical and Design Innovations

The robust steel plate housing incorporates a versatile test head featuring three working pistons for blanking, sheet holding, drawing, and ejecting processes. User-friendly adjustments for drawing and sheet holding force, an automatic test sequence, and a resistive touch panel for smooth operation are key highlights. Additionally, its innovative bayonet lock system simplifies access to and exchange of drawing dies and other components, ensuring a seamless testing workflow.
