Особливості профілювання одно- та трьохзахідних гвинтоподібних труб

Особливості профілювання одно- та трьохзахідних гвинтоподібних труб

Abstract

The simulation of several options roller spinning one- and three-start helical groove on the tube using a software package Deform 3D was conducted. As profiling elements for obtaining grooves were used rollers and the mandrel. The effect of various parameters (diameter roller Dp, screw pitch of the tube k, groove depth h, frequency of rotation of the mandrel n) on the stress-strain state of the tube was investigated. Proposed technology and design spinning-head to obtain three-start helical groove on the tube. Проведено моделювання декількох варіантів обкочування роликом одно- та трьохзахідних канавок на трубі з використанням програмного пакета Deform 3D. В якості профілюючих елементів для отримання канавок використовували ролики та оправку. Досліджено вплив різних параметрів (діаметра ролика Dp, кроку гвинта k, глибини канавки h, частоти обертів оправки n) на напружено-деформований стан труби. Запропоновано технологію та конструкцію обкатної головки для отримання трьохзахідної гвинтової канавки на трубі.
