Portable manually controlled pipe-bending apparatus provided with reversible bending members |
摘要 |
Portable manually-controlled hydraulic pipe-bending apparatus comprises a coupling head and reversible bending members to reverse the bending direction of a pipe relative to the apparatus. The coupling head has thereon two parallel pins for supporting the fixed bending member, and a piston stem that moves toward and away from the pins to support the movable member. The two arcuate bending members are provided with recesses to receive either the pins or the piston stem, thereby adapting them to reversible mounting for bending a tube in either of two opposite directions.
