Abstract

VCT plate parts for automobile engines are wear-resistant and consist of an inner plate and an outer plate. Most of the existing fine blanking parts use a method of ejecting the product by air at high pressure in the mold, resulting in product defects due to damage and scratching as the product falls. However, this study uses an arm extraction method, moving the product using the arm that guides the product outward in the mold. We conducted a study on the extraction methods of VCT outer plate parts for automobile engines by applying fine blanking technology, and developed an arm extrusion method using 2-cavity die technology for fine blanking to produce VCT outer plate parts.
