Creation of a Machine for Unscrewing (Screwing) Couplings from Oil Country Tubular Goods
For the purpose of import substitution, a machine was designed for opening couplings from oil country tubular goods. The hypothesis is the assumption that one of the options for a successful design of a machine for unscrewing (screwing) couplings is a lightweight design with small dimensions and easy changeover to different pipe sizes. Initially, the existing designs of such machines were studied, the advantages and disadvantages of existing designs were analyzed. Based on the analysis and experience of production activities, a machine was designed for unscrewing (screwing) couplings from oil country tubular goods. A 3D model of the machine was made, drawings of individual parts and assemblies were developed. According to the developed drawings, an experimental model of the machine was created. Tests of the machine, its working capacity in production conditions are carried out. The authors designed a fundamentally new machine, which is small in size, more energy efficient, flexibly reconfigured to different sizes, has a relatively low cost, is easy to maintain, and repairable. The machine is easily integrated into the automatic line.
