Description

Метчики ДЛЯ выполнени  резьбы путем пластического деформировани  металла, выполненные без режущих кромок, в виде винта с заборным конусом, известны.Taps For threading by plastic deformation of metal, made without cutting edges, in the form of a screw with a suction cone, are known.

Особенность предложенного метчика, заключаетс  в том, что на поверхности его удлиненного заборного конуса выполнены плоские лыски со скругленными по нарезке кра ми.The peculiarity of the proposed tap is that flat faces with rounded edges are made on the surface of its elongated intake cone.

Эта особенность метчика облегчает процесс пластического деформировани  металла нарезками метчика при его ввинчивании в отверстие.This feature of the tap facilitates the process of plastic deformation of the metal by cutting the tap when it is screwed into the hole.

На фиг. 1 схематически изображен обш,ий вид метчика и на фиг. 2- разрез по АА на фиг. 1.FIG. 1 is a schematic representation of the general view of the tap and in FIG. 2 is a section along AA in FIG. one.

Предложенный метчик состоит из заборной а, резьбовой б и хвостовой в частей. Заборна  часть затачиваетс  под углом 10-20° на квадрат. Под таким же углом стачиваетс  на конус резьба на заборной части. Сопр жение плоских поверхностей квадрата и резьбы скр тл етс . Резьбова  и хвостова  части метчика аналогичны таким же обычного типа метчиков. Описанный выше метчик может найти применение при нарезании резьб малого диаметра, при необходимости получени  упрочненных износостойких резьб средних диаметров и в р де других случаев.The proposed tap consists of intake a, threaded b and tail in parts. The intake part is sharpened at an angle of 10-20 ° per square. At the same angle, the thread on the intake part is grinded on the cone. Conjugation of the flat surfaces of the square and the thread is concealed. The threaded and tail portions of the taps are similar to those of the usual type of taps. The tap described above can be used when cutting small-diameter threads, if necessary, to obtain reinforced wear-resistant threads of medium diameters and in a number of other cases.

Метчик дл  выполнени  резьбы путем пластического деформировани  металла, выполненный без режущих кромок, в виде винта с заборным конусом, отличающийс  тем, что, с целью облегчени  процесса пластического деформировани  металла по нарезке метчика при его ввинчивании в отверстие, на поверхности удлиненного заборного конуса метчика выполнены плоские лыски со скругленными по нарезке кра ми.A tap for threading by plastic deformation of a metal, made without cutting edges, in the form of a screw with an intake cone, characterized in that, in order to facilitate the process of plastic deformation of the metal by cutting the tap when it is screwed into the hole, flat surfaces are made on the surface of the elongated intake cone of the tap flats with rounded edges.
