Kind Code:
A
Abstract:
A method of using a material processing shears (10), the shears (10) comprising:
first and second jaws (20,30) pivotally connected to each other for relative pivotal movement about a jaw axis (100) between open and closed positions, the first jaw (20) having a first cutting blade (200) with a first cutting edge (200a); and
a fluid driven actuator (50) operatively extending between the jaws (20,30) for selective powered movement of the jaws (20,30) between their open and closed positions, the method comprising:
positioning the shears (10) such that a work piece (190) is disposed between the first and second jaws (20,30); and
cutting the work piece (190) primarily with the first cutting blade (200) such that the cutting of the work piece (190) is predominantly localized at an intersection between the work piece (190) and the first cutting blade (200), while the second jaw (30) predominantly supports the work piece (190) without cutting into it,
wherein the work piece (190) comprises a conductor pipe having inner and outer metal pipes with grouting disposed between the inner and outer metal pipes.
