Avantajlar & Özellikler
A typical test method, for example, is the cupping test to Erichsen (ISO 20482), in which a die is pressed into a clamped test piece until a crack appears. There is no in-flow of the sheet metal. The drawing formability of the sheet metal is determined from the die penetration depth.
Another frequently used test method is the earing test to DIN EN 1669. In this test circular blanks are punched or inserted and drawn into cups (metal flow-in). The deep drawing characteristics of the metal are determined via the percentage ear height ratio.
Other metal forming test methods include square cup tests, hole expansion tests, bulge tests or the determination of forming limit curves.
Overview
The sheet metal testing machines are available in five versions:
