发明名称 Conduit bending tool - for bending standard plastic conduit at ambient temps without internal springs
摘要 <p>Tool has a fixed mandrel with channels slightly narrower, pref. by x 0.87 to 0.93, than standard conduit diameters and of suitable radii of curvature. A support on a pivoted lever can engage a mandrel channel to a limited depth and be pulled around to bend conduit clamped near the beginning of the channel. Lateral compression of the conduit in the undersize channel prevents kinking of the inside of the bend as the conduit is wrapped around the mandrel without needing to insert, position and remove conventional internal bending springs.</p>
