Abstract: A vertically oriented tube bending apparatus includes a vertically oriented support frame, which takes up less floor space than the previously known tubing benders. A tube bending apparatus in accordance with the invention, generally, includes a support frame having a length, a width, and a height, wherein the greatest of these is the height. The apparatus further includes a tubing advance mechanism, attached to the support frame, for advancing a tubing workpiece along a substantially vertical path. A bend die is also provided which is rotatably attached to the support frame and pivotally movable about a pivot axis. The bend die has an outer side edge with an arcuate peripheral groove formed therein to receive a portion of a tubing workpiece. The apparatus also includes a pressure die movably attached to said support frame.

Abstract: An apparatus for bending and cutting metal tubing includes a support base and a number of components attached thereto. A bend die is rotatably attached to the support base, and is pivotally movable about a pivot axis. The bend die has a tube-receiving peripheral groove, and a first blade guide slot formed therein to receive a first portion of a blade therein. The apparatus also includes a pressure die which is movably attached to the support base, including a reciprocally movable first pressure applicator, and a follower slide which is slidably attached to the first pressure applicator. The follower slide clamps against a portion of tubing, substantially opposite the bend die. The follower slide also has a second blade guide slot formed therein, to recieve a second portion of the blade. The apparatus further includes a movable bend arm assembly for contacting and bending a tubing workpiece against the bend die. A blade holder is attached to the support base for holding and supporting a blade.

Abstract: A tube bending apparatus, comprising a tube holding mechanism; a first head member for substantially preventing lateral movement of a first portion of the tube; a unit for translating the tube along its longitudinal axis so as to be substantially adjacent the first head member; a unit for rotating the tube about its longitudinal axis; a bend arm member which is pivotally connected to the first head member; a drive mechanism for rotating the bend arm member so as to contact the tube for bending thereof; and wherein the drive mechanism comprises an electric motor and associated gearing for directly coupling the motor to the bend arm member.
