Oil-well piston hydraulic screw machine

Oil-well piston hydraulic screw machine is fixed indoor, which disassembles and assembles the oil-well pump piston valve screw thread. Because the surface of piston is very glossiness, in oder not to traumatized in disassembly and assembly, you can use hydraulic oil dylinder which drives kava to clamp. Its surface is smooth, low hardness. The clamping force are controlled by overflow valve. The function of oil cylinderis as the back tongst. The master tongs use the master tongs of the screw machine. The speed is fast, and the pulling torque is high.

Main technical parameters

1) Overall dimensions 1800×900×1000

2) Application  Φ38mm、Φ44mm、Φ56mm、Φ70mm、Φ83mm

3) Master tongs torque: 200（kg.m）

4) Back tongs clamping force: 20（T）

5) Total power 20(KW）

Works

Main clamp works: fixed jaw tooth block with its roll in the hyperbolic plane involute staggered roll. Due to the curvature of the involute staggered hyperboloid is progressively smaller, when jaw rollers rolling uphill, turn utterly jaw constantly pushing the center, so as to achieve the purpose of clamping the workpiece.

Back clamp cylinder works using push-pull, use torque principle, to the main clamp force torque required to complete action on the shackle.
