Are 22 to 25 the Same Model of Thread Rolling Wheel?

[PaisleyAnn]

22 to 25 are the same model of thread rolling wheel, and you just need to adjust the stripping gear. 1. Differences in Thread Rolling Wheels: The main distinctions among construction thread rolling wheels are the pitch, the thread angle, and whether they are numbered wheels or single-piece wheels. Numbered wheels have numbers 1, 2, 3 or one dot, two dots, three dots engraved on the three wheels respectively. For 16-22 rebar couplers, the national standard requires thread rolling wheels with a 2.5 pitch, while for rebar couplers above 25, a 3.0 pitch thread rolling wheel is needed. 2. Precautions: The thread rolling machine has poor precision, significant vibration, or operates abnormally; the thread rolling dies are misaligned, causing axial displacement of the rolled part, subjecting the threads to both shear and compressive stresses; the dimensions of the rolled thread blanks are uneven, and the surface is not cleaned properly, containing grinding dust, oxide scale, and dirt.
