A metal bend pipe having a bend portion bent in a semi-circular arc shape is provided, in which an identification part that enables one of the two end portions of the bend portion to be identified as the bending-start side or the bending-end side is provided, and the identification part is integrally formed as a protruding and/or recessed three-dimensional region. Thus, it is possible to easily and reliably identify which of the two end portions of the bend portion is the bending-start side or the bending-end side.

A method of bending a conduit is disclosed. An engagement member is displaced via contact with the conduit and engages a switch. A signal is sent to a microprocessor indicative of a characteristic of the conduit to be bent, in response to engagement of the switch. The microprocessor provides a motor control signal to the motor to control a rotation of the shoe, wherein rotation of the shoe bends the conduit.

Tube bending systems configured to bend a tube. The tube bending systems include a tube bending device and a lubrication system. The tube bending device includes a bending device frame and a bending die assembly. The tube bending device is configured to bend the tube. The bending die assembly is mounted to the bending device frame and includes a bending die against which the tube is selectively bent. The lubrication system is configured to selectively direct a lubrication fluid to the tube proximate the bending die assembly.

A bender includes a rotatable bending shoe having at least one channel therein configured to receive a workpiece, a seat proximate to the bending shoe which is configured to receive the workpiece thereon, and a sensor provided on the seat which is configured to sense the presence of the workpiece. In some embodiments, the sensor is configured to sense an end of the workpiece.

A conduit bender having a unitary frame is mounted to a wheeled base which provides for transportation of the bender. A braking assembly provides for simplified locking of the wheels to secure the bender in a location. The bender is mounted to the base through a pivoting assembly which allows for bending of conduit in either a horizontal or vertical plane. A circuit is provided for controlling the bending operation. An auto-sensing portion of the circuit receives information regarding the characteristics of the conduit to be bent upon placement of the conduit in the bender. A feedback portion of the circuit is used to provide a precise bending operation.

A method for manufacturing a complex-curvature tubular product starting from a metal tube extending along a rectilinear longitudinal axis is provided. The method includes carrying out, by a first bending device, a plurality of first bending operations, each first bending operation being carried out on a respective first straight portion of the metal tube, and in a bending plane passing through the longitudinal axis, so that the metal tube leaving the first bending device has a respective plurality of first curved portions, separated by second straight portions, and carrying out on the metal tube leaving the first bending device, by a second bending device, a plurality of second bending operations, each second bending operation being carried out on one of the second straight portions so that the metal tube leaving the second bending device has, between each pair of consecutive first curved portions, a respective second curved portion, and the tubular product thus obtained has first and second curved portions immediately adjacent to each other.

A tube bending system having a frame, one or more static dies, one or more sliding dies and one or more motors for bending tubes, such as metal tubes, in the form of hoops to create a framework for a greenhouse. The system may include separately leveled frames including a central frame supporting the middle of an arch die, and a pair of lateral frames supporting the lateral sides of the die. An apex clamp on the central frame holds the middle of a straight tube blank against the arch die, while a pair of bending carriages on the lateral frames are displaced to bend the tube blank around the arch die. The apex clamp may move both vertically and longitudinally to cycle between holding the tube blank against the arch die, ejecting the bent tube from the die, and retracting to enable placement of another straight tube.

The disclosed technology relates to a rod bending machine for use with a robotic surgical system in an operating room. The system which is capable to bend rods for surgeries directly in the operating room. The rigidity of the rods is such that the robotic arm alone would have to be huge to provide sufficient forces and torques. This invention introduces bending module integrated into robotic system which allows free bending of rods within limits required for surgeries.
