O.M.T. automotive dies

foto A OMT-STAMPI OKO.M.T. Stampi, headquarters at Rosà (VI), presents a combined follow -transfer die that produces 2 components simultaneously for the automotive industry (n.1 piece right + n. 1 piece left). Starting from coils with 510 width, the die executes the first 10 steps with the follow die: 3 steps for blanking, 1 step for the cavity forming, 1 step for the hole blanking, 5 steps for the piece bending. The last step, executed by transfer, performs the final closing of the piece. The piece conveyance occurs at the die side with the use of apposite pneumatic cylinders. The drawn parts are positioned on conveyor belts that transport the pieces directly to the assembly line. The die sizes are 3500x1500xh750 mm. The component production is performed on 1200-Ton transfer press. The die design was fulfilled by 3D CAD supported by apposite application for the sheet metal blanking. Bending punches and dies are made of Toolox 33 with related coatings, punches and blanking dies are made of hardened 1.2379. All structures are manufactured with 1.0503. The follow die and the transfer die are installed on a single upper and lower junction plate for the die fixing on the press with the aid of fast clamps. All the parts composing the die were manufactured with state-of-the-art machining centres and EDM plants supported by CAM 3D programming. The specimens produced by die were tested and measured with 3D measuring machine. The die delivered to the customer was already tested and ready for the mass production.
