Pipe threader
A pipe threader includes a housing, an electric motor, a battery, a die holder, and a die locking mechanism. The die locking mechanism receives torque from the electric motor and rotates as a result. A cutting die is received in the die holder and the locking mechanism rotationally locks the cutting die in the die holder. The locking mechanism includes a first lock ring and a second lock ring. The pipe threader includes a drive assembly including an electric motor, a multi-stage planetary transmission that receives torque from the motor, and a worm drive that receives torque from the transmission. The pipe threader includes an inertial measurement unit and an electronic processer. The processor receives data from the inertial measurement unit, generates a relative position of the pipe threader by applying a Kalman filter, determining whether the relative position exceeds a threshold, and decreases the motor speed in response.
1 . A pipe threader configured to rotate a die head with cutting dies, the pipe threader comprising:
a housing;
an electric motor supported in the housing;
a battery coupled to the housing to power the electric motor;
a die holder that receives torque from the electric motor causing the die holder to rotate, the die holder defining a rotational axis; and
a die locking mechanism configured to rotationally lock the die head received within the die holder, the die locking mechanism including
a first lock ring on a first side of the die holder, and
a second lock ring coupled to the first lock ring on a second side of the die holder opposite the first side,
wherein the first lock ring and the second lock ring are each configured to rotate about the rotational axis with respect to the die holder to engage an outer surface of the die head to selectively mount the die head in the die holder, and
wherein the first lock ring defines a first octagonal pattern opening, the second lock ring defines a second octagonal pattern opening, the die head defines an internal octagonal surface portion, each of the first lock ring and the second lock ring is rotatable between an alignment position and a misalignment position, in respective misaligned positions, the first and second pattern openings are misaligned with the internal octagonal surface.
2 . The pipe threader of claim 1 further comprising a detent system, the detent system including a plurality of detents radially disposed about the die holder and a plurality of spring plungers, each spring plunger biasing one of the detents toward and engaging the second lock ring.
3 . The pipe threader of claim 1 , wherein the housing includes a connection loop configured to receive a clamp.
4 . The pipe threader of claim 3 , wherein a handle extends from the housing and the connection loop is integrated with the handle.
5 . The pipe threader of claim 3 , wherein the connection loop is located on a bottom of the pipe threader.
6 . The pipe threader of claim 1 , wherein the housing includes an air intake vent, an air exhaust vent, and a plurality of mesh coverings disposed over the air intake vent and the air exhaust vent.
7 . The pipe threader of claim 1 , wherein at least one light emitting diode is supported in the housing adjacent the die holder.
8 . The pipe threader of claim 1 , further comprising a multi-stage planetary transmission configured to receive torque from the motor, and a worm drive configured to receive torque from the transmission and provide torque to the die holder.
