Method for manufacturing figure-T shaped metal part and figure-T shaped metal part
Provided are a method for manufacturing a Figure-T shaped metal part using a metal plate or a metal rod split by a method for splitting longitudinally an end part of the metal plate or the 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 Figure-T shaped metal part manufactured by such method. The method for splitting 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.
METHOD FOR SPLITTING END PART OF METAL PLATE OR METAL ROD
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.

AUTOMATED SYSTEMS AND METHODS FOR POST-TENSION TENDON MANUFACTURE AND COILING
Automated systems and processes for manufacturing post-tension tendons may comprise a catapuller 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 the seater station may be configured to move among two or more tubs. A manipulator may be employed to move and hang coiled tendons
