Tube bending machines configured to bend a tube at a target bend location. The tube bending machines include a frame, a bending die assembly, and an alignment stem. The bending die assembly is supported on the frame and configured to bend the tube. The bending die assembly includes a bending die, a wheel frame, and a clamp. The wheel frame is coaxially mounted to the bending die. The clamp is configured to secure the tube to the wheel frame. The bending die, the wheel frame, and the clamp cooperate to define an actual bend location where the tube will be bent by the bending die assembly. The alignment system is operatively supported on the frame and configured to align the target bend location with the actual bend location.

This cooling device includes a first cooling mechanism and a second cooling mechanism. The first cooling mechanism includes a first nozzle disposed to be aligned with a heating coil on a downstream side and whose injection direction of a refrigerant is a first injection direction, a second nozzle disposed to be aligned with the first nozzle on a downstream side and whose injection direction of the refrigerant is a second injection direction intersecting the first injection direction, a first valve selectively switching a supply destination of the refrigerant between one and the other of the first nozzle and the second nozzle, and a first control unit controlling the first valve. The second cooling mechanism includes a third nozzle disposed on a side opposite to the first nozzle and the second nozzle with the extension line sandwiched therebetween and whose injection direction of the refrigerant is a third injection direction forming an angle of 20 degrees or more and 70 degrees or less with respect to a bent inner circumferential surface of a bent portion.

A compact, lightweight, portable tubing bender configured to enable one-handed operation. The tubing bender includes a portable housing including a handle portion, a bender shoe operably coupled to the portable housing, the bender shoe defining an arcuate channel configured to restrain a length of tubing along a prescribed arc during bending operations, a guide gear fixedly coupled to the bender shoe, and a guide frame pivotably coupled to the bender shoe, the guide frame including a motor, a driven gear and a guide member, the motor configured to drive the driven gear along the guide gear to pivot the guide frame relative to the bender shoe, so as to move the guide member during bending operations to guide the length of tubing along the arcuate channel of the bender shoe.

A roll bending apparatus includes: a roll pair formed by a pair of rolls disposed facing each other, the roll pair being configured to sandwich an elongated material between the rolls to perform forming on the elongated material; a slide mechanism configured to slide the roll pair in a first normal direction that is a direction normal to a conveying direction of the elongated material on a plane including the conveying direction; and a tilt mechanism configured to rotate the roll pair about a tilt axis that extends in a second normal direction that is a direction orthogonal to the conveying direction and the first normal direction. The slide mechanism further slides the roll pair to change a position of the roll pair relative to the tilt axis.

The present disclosure is directed to remedying a non-conforming feature of an aluminum alloy part. A method may include identifying a yield strength as a function of temperature for a designation of the aluminum alloy part, determining a stress to be applied to the feature to re-form the non-conforming feature to within a dimensional tolerance, correlating the stress to the identified yield strength to determine a process temperature of the part upon applying the stress to the feature, determining a time duration for applying the stress to the feature at the determined process temperature, and applying the stress to the feature of the part, the feature being restrained to oppose the stress, while heating the feature to the determined process temperature, and maintaining the application of the stress and the heat to the feature for the time duration in order to reform the restrained feature to within the dimensional tolerance.
