ABSTRACT:
A pipe bending machine has a moving mold mechanism, which includes two mold seats positioned one above other, and pressing wheels on each mold seat to work with corresponding bending wheels of fixed molds of the machine; the mold seats are moved by means of a rotating power source whose motion is transmitted by means of a roller, which has spiral grooves; each mold seat has a sliding element secured thereto, and a guide post slidable on the sliding element and passing into a corresponding spiral grooves; guiding mechanisms are interposed between the mold seats and the fixed molds for allowing the mold seats to move up and down along a sloping path; when the rotating power source rotates the roller, both the mold seats will move forwards and backwards in crossing directions respectively as well as upwards and downwards in a sloping path respectively.
