Abstract
A die head for cutting threads in a pipe. The die head includes a drive portion, a die retention portion, a cap, and a plurality of windows. The drive portion has a plurality of recesses configured to receive torque from a pipe threading machine. The die retention portion includes a plurality of die posts. Each die post is configured to receive a die having teeth for cutting the threads in the pipe. The cap is coupled to the die retention portion. Each window is defined between each pair of adjacent die posts and the cap. An end of each die adjacent the cap is visible through a corresponding window of the plurality of windows such that all of the teeth of the die are visible through the corresponding window.
Claims15
A die head for cutting threads in a pipe, the die head comprising:
- a drive portion having a plurality of recesses configured to receive torque from a pipe threading machine;
- a die retention portion including a plurality of die posts, each die post configured to receive a die having teeth for cutting the threads in the pipe;
- a cap coupled to the die retention portion, the cap including a plurality of mating posts, each of the plurality of mating posts being configured to mate with one of the die posts and having a protrusion configured to fit within a notch of each die;
- and
- a plurality of windows, each window defined between each pair of adjacent die posts and the cap;
- wherein an end of each die adjacent the cap is visible through a corresponding window of the plurality of windows such that all of the teeth of the die are visible through the corresponding window.
A die head comprising:
- a drive portion having a plurality of recesses configured to receive torque from a pipe threading machine;
- a die retention portion including a plurality of die posts, each die post configured to receive a die, each die post having a top surface opposite from the drive portion, the top surfaces defining a first plane;
- a cap coupled to the die retention portion, the cap including a plurality of mating posts and a plurality of ledges arranged between the plurality of mating posts, each mating post configured to mate with the top surface of a corresponding die post, the plurality of ledges defining a second plane that is spaced from and parallel with the first plane;
- and
- a plurality of windows, each window defined between a pair of adjacent die posts and a corresponding ledge of the plurality of ledges.
A die head for cutting threads in a pipe, the die head comprising:
- a drive portion having a plurality of recesses configured to receive torque from a pipe threading machine;
- a die retention portion including a plurality of die posts, each die post configured to receive a die having teeth for cutting the threads in the pipe;
- a cap coupled to the die retention portion;
- and
- a plurality of windows, each window defined between each pair of adjacent die posts and the cap;
- wherein an end of each die adjacent the cap is visible through a corresponding window of the plurality of windows such that all of the teeth of the die are visible through the corresponding window,
- wherein each die post includes a first half, a second half, and a slot between the first half and the second half, the slot being configured to receive the die,
- wherein the cap includes a plurality of mating posts, each of the plurality of mating posts being configured to mate with one of the die posts, and
- wherein each of the plurality of mating posts includes a first half with a first surface configured to mate against the first half of the die post, a second half with a second surface configured to mate against the second half of the die post, and a third surface in between the first half and the second half, the third surface configured to mate against a top surface of the die post.
