US Patent:

20230064501, Mar 2, 2023

Filed:

Aug 24, 2022

Appl. No.:

17/894229

Inventors:

- Hanover NH, US
Steven Moody - Charlestown NH, US

International Classification:

B23K 26/361
B23K 10/00
B24C 1/04

Abstract:

A computer-implemented method is provided for shaping an edge of a part to be cut from a workpiece using a material processing system comprising a processing head configured to deliver a processing stream. The method includes calculating a start point and an end point of a shaping path proximate to the edge of the part based on a desired edge profile and determining a set of operating parameters to controllably impinge the processing stream about the edge of the part to execute the shaping path from the start point to the end point. The method further includes positioning the processing head normal to a surface of the part and controllably impinging the processing stream at the edge of the part, by the processing head, to shape the desired edge profile.

International Classification:

H05H 1/34
B23K 10/02

Abstract:

A consumable cartridge for a plasma arc torch includes a cartridge frame having a first end and a second end opposite the first end, the first and second ends defining a longitudinal axis, the second end including a plurality of discrete retaining features. The consumable cartridge includes an electrically conductive contact element secured to the cartridge frame by the plurality of discrete retaining features and translatable up to a predetermined distance within the cartridge frame along the longitudinal axis at the second end, the contact element having a core, a proximal surface, and a distal surface. The proximal surface is shaped to contact a torch plunger of the plasma arc torch upon installation into the plasma arc torch and the distal surface is shaped to contact an electrode of the plasma arc torch during an operation of the plasma arc torch.

International Classification:

B23K 10/00
H05H 1/38

Abstract:

A swirl ring for a plasma arc torch includes a body configured to at least partially surround and slidingly engage an electrode of the plasma arc torch. The body includes a first end and a second end opposite the first end, the first and second ends defining a longitudinal axis, and at least one protuberance extending from the second end in a direction of the longitudinal axis. The at least one protuberance is configured to engage a switch of the plasma arc torch for sensing a presence of a swirl ring in the plasma arc torch.

International Classification:

H05H 1/34
B23K 10/00

Abstract:

A torch tip assembly of a plasma arc torch is provided for delivering a diffused stream of plasma arc in a gouging operation. The assembly comprises a nozzle including a nozzle body defining a central longitudinal axis extending between a proximal end and a distal end. A nozzle exit orifice of the nozzle body defines at least a bore for conducting the plasma arc therethrough. The assembly also comprises a counter bore feature, disposed relative to the distal end the nozzle body, fluidly connected to the bore and located distally relative to the bore. At least one of the bore or the counter bore feature has a non-circular cross-sectional shape in a plane perpendicular to the longitudinal axis. The non-circular cross-sectional shape is configured to enable a second non-circular cross-sectional shape in the plasma arc that diffuses the plasma arc.

B23K 9/013
B23K 10/00

US Classification:

2191215

Abstract:

A torch tip for a plasma arc torch includes a body having a first end, configured to attach to the torch, and a second end, where an end wall is disposed. A plasma exit orifice is formed in the end wall. At least two castellations are formed in the end wall. Each castellation has a castellation width defined by the distance between the sidewalls of that castellation. At least one slot is disposed between two castellations. Each slot has a slot width defined by a distance between the sidewalls of its adjacent castellations. The slot width can be at least twice the castellation width. Each slot also has a slot floor and an exterior shape. The slot floor can have slope that tapers toward the first end of the body in an outward radial direction and the exterior shape of the slot can have a generally V-shaped or U-shaped contour.
