Simulation of technology for manufacturing parts by broach through a horn-shaped core

Elbows are fittings used in pipelines for various purposes to change the direction of the pipeline, to create an additional branch from the main pipeline, to change the diameter of the pipeline, etc. And are widely used in industry. This article discusses the modeling of the process of drawing through a horn-shaped core in the QForm 2D/3D program. The workpiece and the tool for modeling technological operations were created in the Compass-3D program. According to the simulation results, technological parameters were determined, according to which an experimental broach was subsequently carried out. The measurement of the parameters of finished products showed that the simulation results were very close to the results of experimental broaching. The visual correspondence of real branches to their three-dimensional models was also shown. The resulting bends are recognized as fit, fully satisfying the requirements of the technical specifications. Thus, it is shown that the use of the QForm software package at enterprises producing steeply curved bends is expedient and will reduce the time it takes to put a new product into production.
