DEVICE FOR ELECTROTHERMAL TREATMENT OF SHEET BAR Russian patent published in 2001 - IPC

Abstract RU 2170771 C2

FIELD: plastic metal working with heat treatment, particularly, blanking from titanium alloys. SUBSTANCE: device has two upper and two lower hold-down member interconnected in pairs by metal plates, and power source for heating. Blank is placed between plates made of material whose electric conduction is similar to that of treated blank. Plate outer surface is coated with heat-insulating material. EFFECT: consumption in plastic deformation of sheet parts. 2 dwg
