Rolling wheel design design features three axial feed roller pitch selection due to the relationship between the angle of the wheel to move the affected wheel manufacturing pitch P1 and the pitch P of the workpiece can be calculated as follows: helical axial feed rollers: K = P.Sinα.Sin (α / 2 + r) / Sin (90 ° -α / 2) Sin (90 ° -r) two rolling wheels screwed to the same ring rolling wheels are rolling and screwed to the contrary wire wheel manufacturers, installed in the shaft of mutual equality. Tooth pattern shifted by a half pitch. When working with the two rollers, constant rotation on the intermediate support on the rolling machine rolling wheel machining, diamond straight thread, steel sleeve production technology advantages of this connection method is as follows: easy to detect: When construction does not require a specific detection equipment, just to see Ruth teeth steel outer case to determine the quality of the joint. Applicability: Applicable to all seismic and non-reinforced connecting earthquake reinforced concrete structural engineering, and bending steel, fixed steel, steel cage, long steel, etc., and can not turn the occasion apply.
