A portable tubing bender configured to automatically bend a portion of tubing according to a defined set of bend specifications, including a desired number of bends and a desired angle for each bend. The portable tubing bender including a driver configured to rotate a driven shaft and a first rotational output, a reductive gear set operably coupling the driven shaft to an output shaft, a bender shoe couplable to the output shaft, the bender shoe defining an arcuate channel configured to receive tubing during bending operations, and an automatic feed mechanism configured to advance the tubing relative to the bender shoe from an initial position to a bend position.

Machine for working tubes, in particular a hairpin bender machine for simultaneously working a plurality of tubes intended, in particular, to make heat exchangers, said machine comprising a device for feeding and moving tubes to be worked, a unit for bending said tubes, a cutting member configured to cut said plurality of tubes.

A bending machine has a main spindle which supports a die. There are two counter dies each mounted on a working arm which rotate about the main spindle. The working arms are driven by link arms which are acted on by a translational drive. There is versatile three-point bending caused by three die points, two on the working arms and one on the die support shaft. The working arm drive includes a translational component which extends through the die support shaft, and which is connected to the link arms. This achieves excellent symmetry and compactness.

A device and method for bending strand-shaped workpieces are described with a holder for a strand-shaped workpiece. A bending tool comprises at least one radius part and one bending part. The workpiece can be bent by pivoting the bending part about the radius part. A workpiece drive shaft that extends at least in a longitudinal direction is provided for driving the bending tool and a positioning device for positioning the bending tool relative to the workpiece. The positioning device allows a displacement of the bending tool and the tool driveshaft in at least one transverse direction that runs transversely to the longitudinal direction. A drive wheel is rotatably arranged around an axis that is fixed relative to the workpiece and is coupled via a transmission device to drive the tool driveshaft. The transmission device has a coupling element that can move transverse to the axis of the drive wheel.

Devices and methods for bending or cutting implants are disclosed herein. In some embodiments, an instrument can convert a rotational input force (e.g., supplied by a powered driver tool) into movement of a first rod holder with respect to a second rod holder. Such movement can form a bend in a rod or other implant held by the first and second rod holders. Various mechanisms for converting this movement are disclosed, such as a worm drive mechanism and a conical gear mechanism, as are various types of rod holders, including orbiting rollers, lid-type rod holders, fixed and pivoting half-pipe rod holders, and full-pipe rod holders. In some embodiments, the instrument can also be used for cutting, for example by rotating a cutting wheel with respect to a cutting plate to cut a rod or other implant inserted through openings formed in the cutting wheel and the cutting plate.

A robotic system may include a robot base and a rod feeding subassembly coupled to the robot base that includes a feeding actuator configured to selectively move a surgical rod. The robotic system may include a brake subassembly coupled to the robot base that includes a brake actuator configured to receive the surgical rod from the rod feeding subassembly, and selectively fix a first portion of the surgical rod with respect to the brake subassembly. The robotic system may include a bending subassembly coupled to the robot base that includes a bending actuator configured to selectively rotate to engage a second portion of the surgical rod and bend the second portion of the surgical rod with respect to the first portion of the surgical rod so that the first portion and the second portion of the surgical rod define a first bend angle.
