CONTINUOUS PRESSING SYSTEM BY WELDING OF BAR STOCK

PURPOSE:To reduce manhour based on insertion and elimination of each stock by transferring a bar stock through a material supply device to a welding device, welding the next stock to the end of the stock into one body and supply ing it to a press apparatus to press it. CONSTITUTION:When pressing advances and the stock A reduces, the absence of the stock is detected by a stock detecting sensor 9, pressing is stopped, the next stock is supplied and transferred as far as the position of an abutting block 15 for the next stock. Then, a clamp setting part 18 on the side of the material supply device moves, the end faces of both stocks are brought face to face with each other, a welding torch 20 moves and is positioned by stoppers 23, 24 to decide a welding position, welding is carried out at a position to bring them face to face with each other, the stocks are integrated into one body, the stock A is supplied again into the press device 1 and pressed. Consequently, welding can be performed automatically without any manual work. In other words, reduction of man hour by insertion and removal of the stocks one by one can be made and moreover production of scraps from the stocks is eliminated.
