An automatic machine for bending and lock-seaming sheet metal parts from strips or coils of stock by a patented process is illustrated in Fig. 1, while Fig. 2 shows some of the sections which can be formed. This machine is a recent development of the Stolp Co., Inc., Geneva, N. Y. The machine is equipped with a self-feeding attachment. The stock, on being fed into the machine, is first pressed into a U-shape by a punch, after which a round mandrel enters the blank from the rear and pushes it endwise through lock-seaming dies. The mandrel is fastened to a crosshead connected to a chain. This chain runs continuously and carries the crosshead back and forth the entire length of the frame.
As the mandrel reaches the farthest back position, the if-shaped punch descends and presses the blank into a position in line with the mandrel. The mandrel enters the blank as the punch leaves it and carries the work forward as previously explained. The lock-seaming dies have no moving parts, but they are so constructed that the blank is closed and the lock-seam produced in one operation. The machine will lock-seam taper tubes within certain limits. Among the many parts which can be produced on this machine are tubes for mufflers and radiators, blowers and ventilators. |
