Claims (5)

1. Способ формирования наружной резьбы на концевом участке трубной заготовки, преимущественно на ниппельном конце переводника для насосно-компрессорных труб, включающий размещение концевого участка трубной заготовки в матрице с внутренней резьбой, профиль которой соответствует профилю изготовляемой на заготовке резьбы, и раздачу изнутри указанного концевого участка с заполнением металлом заготовки резьбовых канавок матрицы, отличающийся тем, что предварительно изготавливают трубную заготовку с наружным диаметром концевого участка, равным внутреннему диаметру резьбовой матрицы, и внутренним диаметром, определяемым из выражения
Figure 00000001
, а раздачу концевого участка осуществляют за один проход коническим пуансоном с калибрующим пояском, диаметр которого равен внутреннему диаметру готовой детали,1. The method of forming the external thread at the end section of the tubular billet, mainly at the nipple end of the sub for tubing, comprising placing the end section of the tubular billet in a matrix with an internal thread, the profile of which corresponds to the profile produced on the workpiece thread, and distribution from the inside of the specified end section with metal filling of the workpiece of the threaded grooves of the matrix, characterized in that the prefabricated pipe workpiece with an outer diameter of the end section equal to the inner diameter of the threaded matrix, and the inner diameter determined from the expression
Figure 00000001
and the distribution of the end section is carried out in one pass with a conical punch with a calibrating girdle, the diameter of which is equal to the inner diameter of the finished part, где Dзв - внутренний диаметр заготовки;where D stars - the inner diameter of the workpiece; Dn - диаметр пуансона;D n is the diameter of the punch; Dрн - наружный диаметр изготовляемой резьбы;D pH - the outer diameter of the manufactured thread; Dрв - внутренний диаметр изготовляемой резьбы.D PB - the inner diameter of the manufactured thread. 2. Способ формирования наружной резьбы по п.1, отличающийся тем, что конический пуансон выполнен с углом конусности 2-3°.2. The method of forming the external thread according to claim 1, characterized in that the conical punch is made with a taper angle of 2-3 °. 3. Способ формирования наружной резьбы по п.1, отличающийся тем, что на резьбовые канавки матрицы и поверхность пуансона наносят смазку.3. The method of forming an external thread according to claim 1, characterized in that a lubricant is applied to the threaded grooves of the matrix and the surface of the punch. 4. Способ формирования наружной резьбы по п.1, отличающийся тем, что заготовку перед пластическим деформированием нагревают до температуры, ниже температуры начала окалинообразования, и ведут деформирование в режиме полугорячей штамповки.4. The method of forming the external thread according to claim 1, characterized in that the preform is heated before plastic deformation to a temperature below the temperature of the onset of scale formation, and the deformation is carried out in the mode of half-hot stamping. 5. Способ формирования наружной резьбы по п.1, отличающийся тем, что формирование резьбы осуществляют с использованием подпорного кольца, внутренний диаметр которого больше диаметра калибрующего пояска пуансона на величину зазора, обеспечивающего вытекание избытка металла после заполнения профиля резьбовой матрицы.5. The method of forming the external thread according to claim 1, characterized in that the forming of the thread is carried out using a retaining ring, the inner diameter of which is larger than the diameter of the calibrating punch belt by the amount of the gap that allows excess metal to flow out after filling the profile of the threaded matrix.
