摘要

A pivot link for interconnecting a locking bar and a pivoting arm of a sheet bending brake includes an arm portion and a locking bar portion. The arm portion defines a first threaded bore, and the locking bar portion defines a second threaded bore. A threaded stud extends between and interconnects the arm portion and the locking bar portion, and is disposed in threaded engagement with both the arm portion and the locking bar portion. The threaded stud includes a first thread portion in threaded engagement with the first threaded bore, and a second thread portion in threaded engagement with the second threaded bore. The first threaded bore and the first thread portion include one of a left hand thread or a right hand thread, and the second threaded bore and the second thread portion include the other of the left hand thread or the right hand thread.

主权项

1. A sheet bending brake comprising:
a frame member having a lower leg extending outward to present a lower clamping surface, and an upper leg extending outward in spaced relationship relative to the lower leg; a pivoting arm pivotably attached to and extending outward from the frame member to present an upper clamping surface for engaging the lower clamping surface; a locking bar rotatably connected to the upper arm of the frame member for rotation about a longitudinal axis of the locking bar; and a pivot link interconnecting the locking bar and the pivoting arm, and operable to move the pivoting arm between an open position and a clamping position in response to rotation of the locking bar about the longitudinal axis of the locking bar, the pivot link including:
an arm portion rotatably attached to the pivoting arm for rotation about a first link axis;a locking bar portion rotatably attached to the locking bar for rotation about a second link axis; anda threaded stud extending between and interconnecting the arm portion and the locking bar portion, and disposed in threaded engagement with both the arm portion and the locking bar portion.
