Automated systems and processes for manufacturing post-tension tendons are provided. In one embodiment the system may comprise a conveyor configured to introduce a pre-determined length of a tendon into a tub; a cutter configured to cut the tendon when it meets the pre-determined length; and (c) a control unit configured for a user to input the pre-determined length and a pre-determined bundle diameter. The control until is typically operably connected to the cutter and to the tub. Advantageously, the tub is configured to coil the tendon to form a tendon bundle and tie the tendon bundle in the predefined bundle diameter. A movable seater station may be employed to fasten an anchor to one end of the strand and said seater station may be configured to move among two or more tubs. A manipulator may be employed to move and hang coiled tendons.

A method for manufacturing metal parts with split ends joined. An end of a metal plate or solid metal rod is split. The length of the incision is adjusted and a smooth split face is formed. A metal plate is secured by pinching both sides with a clamping device, or a solid metal rod is pinched on opposite portions on the periphery with a clamping device. The plate/rod is split longitudinally by slitting or cleaving the plate/rod by pressing a slitting or cleaving punch against the face of one end of the plate/rod. The splitting is advanced by repeating the operation of pressing the punch against the cleft of the splitting. In each splitting operation, the position of the clamping device is moved in advance of the next pressing by a stroke corresponding to the distance from one end of the plate/rod, to the distal end of a split-desired portion.

Provided are a method for splitting longitudinally an end part of a metal plate or a metal rod having a rectangular, polygonal, or elliptical shape, in which the length of incision in the split portion can be freely adjusted and smooth split face can be formed; a metal part manufactured by such method; and a method for bonding such metal part. The present invention is characterized by the process comprising the steps of securing a metal plate by pinching both sides thereof with a clamping device, or securing a metal rod by pinching at least two opposite-facing portions on the periphery thereof with a clamping device; splitting longitudinally by slitting or cleaving the metal plate, or the metal rod, by pressing a slitting punch or a cleaving punch against the face of one end of the metal plate, or the metal rod; and advancing the splitting further by repeating the same operation of pressing the same punch stated above against the cleft of the splitting; and is characterized further in that, in each time of the press-splitting operation, the position of the clamping device on at least one side is moved in advance of the next pressing by a stroke corresponding to the distance from one end of the metal plate, or the metal rod, to the distal end of a split-desired portion.

A notching device includes a base, a stand, a lever assembly, and a notching assembly. The base and stand are coupled together. The lever assembly is coupled to the stand and the notching assembly. The notching assembly includes a die set. The die set has a two-tier upper shoe and a lower shoe. The two-tier show has a first tier and a second tier separated by a gap and the lower shoe includes a notch. The two-tier upper shoe fits within the lower shoe.

A portable machine includes a controller to receive target parameters associated with a workpiece to be worked. A front assembly includes a first baseplate which is stationary during operation, a first actuator to controllably move the workpiece bidirectionally along a longitudinal axis thereof, a second actuator to controllably rotate a second baseplate relative to the first baseplate, and at least one tooling unit. A rear assembly includes a third baseplate with a rolling base, a fourth baseplate rotatably coupled to the third baseplate, and a rear workpiece clamp. Sensors generate signals representing a distance between the first and third baseplates, an orientation of the first baseplate relative to the second baseplate, and an orientation of the third baseplate relative to the fourth baseplate. The controller generates control signals to the tooling unit and the first and second actuators based on at least the target parameters and the sensor signals.
