PURPOSE: An expandable pipe forming bending machine is provided to enable a long steel sheet to be bent into a round shape without any limitation of the length of a pipe to be manufactured. CONSTITUTION: An expandable pipe forming bending machine includes bodies (100), upper connecting bodies (200), an actuator, bending knives (400), bending dies (500), transfer rollers (600), and pushing units (700). The body is composed of a bed (110), a column (120), and a crown (130). The upper connecting bodies connect the crowns of the bodies which are separately arranged in a row. The crowns and the upper connecting bodies are assembled to be detached. The crowns, the bending knives, and the bending dies are arranged to be eccentric to a side out of the centers of the bodies. |
