Abstract
The penetration bending method is adapted to bend a rod-like member by allowing the rod-like member to penetrate through a guide cylinder and a die in a condition where the central axis line of the guide cylinder which restrains the rod-like member so as to travel straight is offset relatively from the center of a bearing portion of the die which restrainedly bears a portion of the rod-like member penetrating through the guide cylinder. This method permits easily bending the rod-like member with high precision, without changing the shape of its cross section and with high roundness. The penetration bending machine comprises a guide cylinder, a die, a driving device for changing relative position of the guide cylinder and the die, an input device for inputting data on mechanical natures of the rod-like member and bending conditions therefor, a first memory for storing the data inputted from the input device, a second memory for storing data for displacing the guide cylinder and/or the die, and a drive control device for controlling the driving device referring to the data stored in the first and second memories.
