<p>There is provided a new and useful slip lock forming apparatus comprising a support structure having a transverse open area on one side thereof for inserting the end of a workpiece; a forming die mounted transversely on the support structure to lie adjacent one surface of a workpiece when the workpiece is inserted through the opening, the working surface of the die oriented generally in the direction of insertion of the workpiece, the die adapted to cooperate with a forming bar to bend a terminal section of the workpiece in a reverse direction and to bend a part of the terminal section in a forward direction relative to the direction of insertion of the workpiece, whereby a terminal S or Z configuration is imparted to the end of the worpiece; a clamping mechanism mounted on the support structure in the opening and comprising a pair of clamping members at least one of which is movable between an open and a closed position for holding the workpiece in position relative to the die; a press mechanism oriented transversely of the opening and comprising a pair of pressing surfaces at least one of which is movable relative to the other between a first position in which the surfaces are substantially in contact and a second position in which the surfaces are spaced from each other, the pressing surfaces lying on opposite sides of a workpiece when the workpiece is inserted into the apparatus; and a forming bar mounted on the structure and movable between a retracted position and an extended position for forming a workpiece around the die.</p> |
