ARAGON-GONZALEZ, G.; CANALES-PALMA, A.; LEON-GALICIA, A.  e  MORALES-GOMEZ, J. R.. Design of a torque generating mechanism. J. appl. res. technol [online]. 2007, vol.5, n.3, pp.65-71. ISSN 2448-6736.

The design and assembly of a mechanism to bend schedule 80 stainless steel pipe up to 1½ in nominal diameter is presented. The use of a relatively small hydraulic actuator, coupled with a toothed wheel to produce the bending torque, is a novel approach to the process. The bending method uses two arms and a radius block in order to accomplish the bending. The hydraulic power consumption in the machine is very small (750 W, 3.4 MPa, 11.4 in/min). The strongest restriction upon the design is that it could be manufactured in small shops, with a cost low enough to be profitable even for a small production volume.
