Abstract
A machine used in tube fabrication, wherein the machine imparts a locating feature near an end of a tube when the tube is located between a clamp die and a bend die of the machine by using a crimp die to form detents and bulges in the tube. The locating feature enables the tube to be located in a larger tube.
Claims12
A machine to put a locating feature in a tube, comprising:
- a bend die having a first recess;
- a clamp die having a second recess, wherein the first and second recesses are adjacent to each other to form a cavity which enables the tube to pass through the cavity in a Z direction and be held in place, wherein X, Y and the Z directions are perpendicular to each other;
- and
- a crimp die movable in the X direction, the crimp die having a first crimp die edge angled relative to the X direction and which puts a first detent in the tube as the crimp die moves in a positive direction along the X direction to create a bulge in the tube extending beyond an outer circumference of the tube;
- wherein each of the bend die and the clamp die have a slot through which the crimp die moves in the positive and a negative X direction opposite the positive X direction.

- wherein the crimp die has second through fourth crimp die edges, wherein the second through fourth crimp dies edges are angled relative to the X direction, wherein the second crimp die edge puts a second detent in the tube as the crimp die moves in the positive X direction, and the third and fourth crimp die edges put third and fourth detents in the tube as the crimp die moves in a negative X direction along the X direction;
- and
- wherein each of the bend die and the clamp die have a slot through which the crimp die moves in the positive and a negative X direction opposite the X direction.
