Abstract: An application for a device that bends a workpiece includes a rotary hydraulic actuator. The rotary hydraulic actuator is fluidly coupled to a controlled source of hydraulic fluid pressure and has an rotating flange that turns responsive to the hydraulic fluid pressure. A bending member is coupled to the rotating flange of the rotary hydraulic actuator and rotates responsive to the rotational motion of the rotating flange. A bending mandrel is mounted on a face of the bending member at a center of rotation of the bending member and a force mandrel mounted on the face of the bending member. An actuator controls the hydraulic fluid pressure and clips are provided for attaching the device for bending to a boom of, for example, a skid-steer loader.

Abstract: A hydraulically rebar bender for skid-steer loader includes a structural case with quick-attach flanges for attachment to skid-steer loaders. The case has an adjustable work tray mounted on the face for supporting the rebar when bending. One end of a hydraulic cylinder is connected to the case and a distal end is connected to a rack gear. The rack gear mates with a pinion gear that is mounted on an axle. The pinion gear is connected to a bending disc that rotates with the pinion gear. A force shaft is mounted on the bending disk. The force shaft travels in a circular cutout of the case and accepts various size mandrels. The axle protrudes out of the case and has a bend mandrel mounted thereon. Hydraulic power is supplied by the skid-steer loaders hydraulic system via hydraulic supply hoses.

Abstract: An exemplary method for making a metallic cover includes the following steps: providing a raw metallic block (20); rolling a pressing machine (30) on the metallic block to form a preformed body (40); and machining the preformed body 40 in a high precision machining process to yield a metallic cover (60). The thickness of a predetermined portion of the metallic cover is different from that of other portions of the metallic cover.

Abstract: An improved tubing bender of the type having a mounting base, a mandrel mounted upon the mounting base and having a tube recess, and a tube retainer mounted upon the mounting base. It is improved by the tube retainer being mounted upon the mounting base by a snap-lock journal.

Abstract: An automated crimping machine for crimping a fitting or end connector onto an end of a cable is made up of segmental die portions which together form a die surface in the desired configuration including cylinder-operated pivot blocks to advance the segmental die portions between an open position and closed crimping position, a plunger assembly axially spaced from the die portions to support the fitting in loosely assembled relation on the cable and to automatically advance in an axial direction into the cavity formed by the die surfaces to cause the fitting to be crimped onto the cable end, following which the segmental die portions are expanded away from the fitting and the crimped fitting removed to permit insertion of the next fitting and cable which is advanced through a guide block into properly aligned relation with the plunger.

Abstract: A bending tool for bending rods or like items, and including two handles and three bending posts. Two of the posts move with the handle, and the third post is a center post which is selectively rotatable to positions for determining the bend in the item. A pin interconnects the handle and the center post to hold the latter in its selected position during the bending process.

Abstract: There is disclosed a tool for bending wire, electrical cable, tube and rod. The tool comprises a base plate. On the first surface of the base plate there is a socket for receiving the drive stud from a ratchet wrench or there is a recess in the base plate for receiving the drive stud from a ratchet wrench. On the second surface there are two spaced-apart guides. The wire for electrical cable or tube or rod can be placed between the two spaced-apart guides. The tool can be moved and rotated so as to bend the wire, electrical cable, tube or rod to the desired configuration. A guide may have a roughened surface or knurled surface to assist in positioning the wire or rod being worked with the tool.

Abstract: A cam action surgical rod bender includes a locking assembly which locks a bending knob in place. The rod bender includes a knee lever configuration for keeping the bending knob still, wherein a pin is moved downwardly along a channelled cam surface to provide stability when locking the bending knob in place against the round support plate at the hinge portion of the rod bender.

Abstract: An orientable bending assembly of a type capable of being temporarily retracted below the upper edge of a work platform (15) of a bending-shaping machine for sections is disclosed. The bending assembly is provided with clockwise and anticlockwise rotation of a bending pin (18) and contrast roll (12). A bending, e.g., disk (11) cooperates with and is supported by an orientable slide block (14) pivoted on an orientation pivot (16) lying in the neighborhood of a plane comprising the axis of the contrast roll (12), this plane being substantially parallel to the axis of the section or sections being bent and shaped.

Abstract: A bending machine for bending wire, tubing, or other elongate material, comprising a support structure and a bending head which is mounted on the support structure and which is capable of bending such material in a given plane which is fixed relative to the bending head. A feed unit is mounted on the support structure and is arranged to feed such material along a feed axis of the machine to the bending head. The bending head is rotatable about the said feed axis of the machine thereby to enable the machine to bend the material into more than one plane. Furthermore, substantially the whole of the bending head is positioned to one side of the said feed axis of the machine.

Abstract: A slit fin heat exchanger is formed by wrapping slit fin tubing into a flat coil having two spaced rows of tubing. The flat coil is located on mandrels which are rotatable about spaced parallel axes with the mandrels and axes initially being in the same plane. The mandrels are rotated about their axes in opposite directions which shifts the plane in which the coil is located. The shifting of the plane of the coil moves a portion of a first row of the coil into contact with a planar portion of a platen and the second row of the coil into a nesting relationship with the portion of the first row which is in contact with the planar portion of the platen. Continued rotation of the mandrels causes folding of the portions of the coil which extends the area of nesting. The folding takes place through up to 120.degree. and the ends of the first row of the coil contacts a portion of the platen causing the formation of a knob at the end of each coil.

Abstract: For straightening of bent pipes a device with a base in two parts provided for spanning the bent pipe on one longitudinal side of the bend of the pipe. One base is connected to one end of a tie bar, which is pivotally fastened at the other end to a piston rod in a working cylinder. The working cylinder is pivotally fastened to a corner of a triangular straightener, another corner being pivotally fastened to one part of the other base, and the side opposite this corner bearing a thrust block or roller, which presses against the other longitudinal side of the bend of the pipe.

Abstract: An improved L-shaped seal for a turbine regenerator and a method of making same. The seal has a curved leg which contacts a mating surface. The curve urges the seals leg into contact about the periphery of the seal even when there is no gas pressure in the regenerator.
