Abstract
Cutting or welding torch component comprising a ridge (8) forming a thread for connecting the component to other parts of the cutting or welding torch, the thread having a pressure flank (81, 91), a clearance flank (82, 92), a root flat (84, 94) and a crest flat (83, 93), wherein—the angle included by the pressure flank (81, 91) and clearance flank (82, 92) is 60° or less, —the angle α included by the pressure flank (81, 91) and a plane perpendicular to the longitudinal axis (10, 20, 30) of the thread is 40° to 50°, —the angle β included by the clearance flank (82, 92) and a plane perpendicular to the longitudinal axis (10, 20, 30) of the thread is 0° to 20°, and—the height (VZ) of the ridge (8) is 0.4 times the pitch of the thread or less.
Claims9
A cutting or welding torch component, the cutting or welding torch component comprising:
- a ridge forming a thread for connecting the cutting or welding torch component to other parts of a cutting or welding torch, the thread having a pressure flank, a clearance flank, a root flat, and a crest flat, wherein:
- the thread is a single start thread,
- an angle included by the pressure flank and the clearance flank is 60° or less,
