It was originally established as Milford Fabricating, a company that made automobile body prototypes. The hot stamping process involves heating steel blanks in ovens and then, stamping the hot blanks in a stamping press. The stamped parts are held under tonnage until partially cooled. The temperature the blanks are heated to, the amount of time they are heated, the time it takes to get the blanks into the stamping die, and the time the parts are held under tonnage, are all key process parameters. Water circulates through the dies to cool the stampings. MFHS Line 1 includes a gas fired tunnel oven followed by a stamping press made by the Indian company ISGEC. Robots remove blanks from a pallet and deposit them on a table. The walking beam raises the blanks off the table and moves them forward. The hydraulically actuated walking beam advances the parts thorugh the oven. At the press end of the oven, the walking beam lowers the parts onto a table. The table moves the blanks under the press. An unloader picks the parts off the table and holds them while the table retracts back under the oven. The unloader lowers the blanks into the lower die halves, retracts, and the blanks are stamped. MFHS Line 2 includes an electric oven, a 500 ton Verson hydraulic press, two date stamper frames, a pallet rack, and three robots. In operation, one robot uses suction cups to remove blanks from a palletized stack. Each blank is moved to the date stamper and a date stamped into it. The blank is then placed on a table that centers it. The second robot picks the blank from the crowder table and places it into the oven. After the blank is heated the right amount, it is removed and placed in the press in the lower die. The press closes on the still orange blank and forms it. The press remains closed while cooling water flows through the die. After the press opens the third robot uses magnets to remove the part and drop it on a conveyor. http://www.martinrea.com/Public/Detroit 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Martinrea」の詳細全文を読む スポンサード リンク
