Description
Выдавливание витков нарезки на проволоке 4 может осуществл тьс валиками 5 и валиками 6, плоскости вращени которых перпендикул рны . Валик имеет профиль, обратный профилю нарезки.The extrusion of the thread turns on the wire 4 can be carried out by rollers 5 and rollers 6, the planes of rotation of which are perpendicular. The roller has a profile opposite to the threading profile.
Благодар такой нарезке повышаетс прочность гвозд на 26-30%, упрощаетс технологи его изготовлени и сохран етс высокое сопротивление выдергиванию. Гвоздь с такой нарезкой с диаметром 3 мм имеет сопротивление выдергиванию из древесины сосны 34,5 кгс/см, а такой же гвоздь с кольцевой нарезкой - 33,39 кгс/см.Due to such cutting, the strength of the nail increases by 26-30%, the manufacturing technology is simplified, and the resistance to pulling is maintained high. A nail with such a thread with a diameter of 3 mm has a pull resistance of 34.5 kgf / cm of pine wood, and a similar nail with a circular cut — 33.39 kgf / cm.
