摘要： A pipe fusion machine including a track mounted chassis supporting a horizontal turntable for unlimited, reversible rotation relative to the chassis. A boom pivotally attached at a rear end of, and extending forwardly of, the turntable enables manipulation of elevations and distances of the free end of the boom. The free end of the boom is adapted to permit pivotal mounting thereon of a pipe fusion tool such as an indexer configured to articulate and support a pipe-end facer and a pipe-end heater for respective independent orientation into and out of alignment with the ends of pipes to be fused. A carriage supports fixed and sliding jaws adapted to grip the ends of pipes to be fused for relative reciprocal movement during a pipe fusion process. Each of the jaws may include an upper half jaw and lower left and right quarter jaws.

摘要： One fusion machine can butt or socket fuse polyolefin pipes and fittings in straight alignment or at inwardly or outwardly mitered universal angles from 0° to 45° for butt fusion and from 0° to 10° for socket fusion. The machine is manually driven, hydraulically monitored and operated in all configurations from one side of the machine.

摘要： Modular carriage for varying spacing between ends of polymer pipe during fusion. The modular carriage includes a fixed jaw; an inner movable jaw; an outer moveable jaw and a plurality of guide rods. The fixed jaw being adapted for tool free engagement with the terminal ends of the plurality of guide rods. A carriage cylinder is associated with at least two of the guide rods and mounted for reciprocal travel along the length of its associated guide rod. The movable jaws being adapted for tool free engagement with at least two carriage cylinders for reciprocal travel therewith. A combined hydraulic cylinder/guide rod includes a guide rod with an integral guide rod piston, a cylindrical tube, and a guide rod gland on each end of the cylinder tube.

摘要： A socket fusion jig includes a pipe saddle and coupling saddle spaced apart. Rotation of a handle causes the pipe saddle and coupling saddle to move laterally relative to one another so that the pipe held in the pipe saddle may be fused to the coupling held in the coupling saddle.

摘要： An electro-mechanical machine for fusing small diameter polyolefin pipe includes a carriage and controls. The carriage has fixed and travelling jaws that grip a pipeline and a pipe stick and electrically driven screws that bring the jaws into and out of close proximity for performance of fusion process tasks. The controls include an electrical closed loop circuit that controls operation of the screws to transfer the travelling jaws to a base axial distance from the fixed jaws and an electrical load cell feedback circuit that controls operation of the screws to reciprocate the travelling jaws in relation to the base axial distance in response to feedback from the load cells so as to maintain a predetermined force between the pipes.

摘要： A facer facing the ends of polyolefin pipes for butt fusion is modular in the sense that it employs three types of modules, a drive unit, two blade holders and a motor assembly, that are separable from one another and each independently light enough to be hand-lifted along walls and up to ceilings. The drive unit module is adjustable to accommodate different guide rail spacings. The blade holder modules are interchangeable to accommodate different diameters of pipe. The motor assembly module has multispeed capability to accommodate the total area of material to be faced. Each module can be exchanged or modified without use of tools to change the geometry of the assembled facer to accommodate different fusion machines and/or diameters of pipe within working spaces dictated by the diameter of the pipe and not by a fixed geometry of a facer.
