Abstract:
A pipe bender where the number of actuators can be reduced, operation is easily made even by hand, and even an unskilled user can produce a precisely bent pipe. A pipe bender where a pipe (P) is held by a clamp (15) and a bending die (12) with the pipe (P) received between the groove of the bending die (12) and the groove of a pressure (14) and in that state, the pressure (14) is rotated along the peripheral surface of the bending die (12) to bend the pipe (P). The bending die (12) is placed so as to be recedable from a bending point of the pipe (P). The bending die (12) is moved to the bending point in conjunction with bending operation by the pressure (14), and made to recede from the bending position in conjunction with return operation of the pressure (14).
