FIELD: process engineering.SUBSTANCE: invention relates to metal forming, particularly, to pipe bending. Clamp appliance serves to feed and clamp the workpiece by stationary clamping part and moving clamp. Note here that said moving clamp has the case with two bearing walls arranged on sides with clamp drive fitted at outer surface of one of said walls. Note here that top edges of bearing walls act as cams for opposed spindles extending sideways from hydraulic cylinder hinged to moving clamp. Note also that top edges of bearing walls have two appropriate recess for extending spindles to be locked thereat to retain moving clamp at closed position.EFFECT: expanded performances.5 cl, 8 dwg |
