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.

Robotic rod benders are disclosed including a motor housing and a mechanical housing coupled with the motor housing. The motor housing may include first and second rod feeding/rotating motors, a brake motor, a bending motor, first and second rod feeding/rotating transmission inputs, a brake transmission input, and a bending transmission input. The mechanical housing may include a rod feeding/rotating subassembly, a brake subassembly, a bending subassembly, first and second rod feeding/rotating transmission outputs, a brake transmission output, and a bending transmission output. Separate motor and mechanical housings are also disclosed.

An apparatus for molding a hairpin inserted into a stator core includes a clamping unit including a connection bracket mounted on a front end of a robot arm and at least one clamper mounted on the connection bracket and configured to be reciprocally driven in opposite directions in a straight line, and a mold unit detachably coupled with the at least one clamper and configured to press mold a head portion of the hairpin by a molding jig configured to be driven by the at least one clamper.

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 dual size conduit bender preferably includes a base member, an upper pole support member, a foot support member and a conduit support member. Opposing ends of the upper pole support member extend from a top of the base member. A pole boss extends upward from a top of the base member. The foot support member extends upward from one end of the base member. The conduit support member extends from an opposing end of the base member. First and second curved grooves are formed in a bottom of the base member. A pair of clearance slots are formed in an end of the foot support member. A pair of insertion slots are formed in a top of the conduit support member. A pole bore is formed through a top of the upper pole support member into the pole boss to receive a bending pole.

A device for making efficient Y-pipes has a first piece configured to hold a Y-pipe that has a holder portion and a jaws portion, the jaws portion being moveable between a first configuration and a second configuration, a second piece configured to be inserted into the vertex of a Y-pipe that has a wedge portion and a punch portion, the wedge portion being configured to be inserted into the vertex of a Y-pipe and the punch portion having a tip and fitting at least partially within the wedge portion and being moveable with relation to the wedge portion between a retracted position and an extended position, and a control system configured to control the movement of the jaws portion and the punch portion such that a Y-pipe held between the first piece and second piece has its vertex angle decreased.

A tool, such as a conduit bender, that includes a gear assembly for providing a mechanical advantage when bending a workpiece conduit. The gear assembly comprises a pinion gear rotatably coupled to a handle, the handle including a pin that can be selectively engaged with the pinion gear. The conduit bender also includes a shoe with teeth that protrude radially inward from a curved outer portion. When the conduit bender is in use, the teeth of the pinion gear engage with the teeth of the shoe.

A mine bolt bending system includes a frame comprising a plurality of bolt receiving portions each configured to receive and hold a mine roof bolt, a bolt contact member secured to the frame, with the bolt contact member rotatable relative to the frame between a first position and second position, and an actuator secured to the frame, with the actuator configured to move the bolt contact member between the first and second positions. The bolt contact member is configured to bend a mine bolt when rotating from the first position to the second position.
