1 gru 2022 · The backward flow forming process is numerically modelled with the finite element method (FEM) based on FORGE® NxT 3.2 software, which is used in this work. In order to obtain all elasticity, thermal, physical, and plasticity properties of the AISI 5140 steel material, JmatPro Software is used.
Objectives. By the end of today you should be able to... ...describe different forming processes, when they might be used, and compare their production rates, costs and environmental impacts. ...calculate forming forces, predict part defects (tearing, wrinkling, dimensional inaccuracy), and propose. solutions.
1 lis 2003 · This paper begins by classifying and describing process details of spinning and its allied process, shear forming and flow forming and follows by outlining developments in machine tools. In addition, research carried out in the area of these manufacturing processes is reviewed.
As its name describes, this advanced metalworking process forces the material to “flow” into the desired shape. In addition, flow forming starts with a machined, forged, or deep-drawn tube or cup-shaped “preform” that is much thicker than the thin circular disk found in spin forming operations.
23 sty 2023 · This paper proposes a novel flow forming process named two-stage flow forming (TSFF) to manufacture the thin-walled tubular parts with deep longitudinal outer ribs. The TSFF process includes two forming stages of preforming and final forming.
Spinning is a very effective method of forming complex shape axisymmetrical products [1]. Flow forming means shaping a product of sheet metal, tube or drawpiece in one are more passes of the forming roll or rolls. The magnitude of wall thinning depends on the properties of the input material and the number of passes.
1. Introduction. The flow forming process is becoming more used in forming industry. After its initial introduction in 50s-60s and its use as an alternative of deep drawing, this process felt into obscurely for long time regarding its industrial application.
