PURPOSE:To elevate workability and to make a device compact, by switching a lever of one set device so that bend-working is performed easily in both forward and reverse directions. CONSTITUTION:A wire rod is inserted through between clamping rollers 32, 32', and a rock arm 38 is fixed to the upper part of the roller 32' by a stopper pin 39. When a handle 13' is turned, rotary torque given to a rotating shaft 12 turns an arm 25, and the other roller is turned around the roller 32'. Accordingly, the wire rod is bend-worked, the lock arm 38 is opened, and the wire rod 5 is moved ahead. Subsequently, the switching handle is switched and turned in the opposite direction, a switching arm 44 is inclined in reverse, a driving shaft 22 is lowered, and an arm 18 and the rotary shaft 12 are disconnected. On the other hand, the rotating shaft 12 rises and locks both arms 18, 25 in one body. Therefore, when the handle 13 is turned in the opposite direction to the handle 13', turning torque is transmitted to the high rank arm 25 from a deflecting shaft 23, the roller 32' is turned to the left around 32, and the wire rod 5 is bend-worked in the opposite direction. |
