Method for Pocket Die Design on the Basis of Numerical Investigations of Aluminium Extrusion Process
A typical extrusion of low and medium strength aluminium alloys solid shapes is performed with flat pocket dies. The pocket allows realising the extrusion as “billet-to-billet” process, and also facilitates filling-up die channel deadlocks and thin-walled elements of profile [1]. In addition it serves as an instrument for shape geometry control. The scientific literature contains a variety of r...
متن کاملEffect of Die Profile on Mechanical Properties of Product in Extrusion of Rods
In any metal forming process, both the strain rate and deformation rate depend on the die profile. The die profile also, is responsible for the non-uniformity of the deformation along the cross-section. These affect the quality and mechanical properties of the product. Therefore, if a die is designed, in which the affecting variables can be controlled spontaneously it is hoped to obtain a produ...
متن کاملSimulating Die Swell in the Context of Profile Extrusion
Plastics extrusion is a manufacturing process suitable for continuous profiles such as floor skirtings, window frames, and pipes. In industrial applications, extrusion is a large-scale process, financially attractive only for mass products. This is due to the time consuming and costly regulation of the extrusion process and especially, the design of an extrusion die which relies on running-in e...
متن کاملGeometry Modeling for Cotton Leaf Based on NURBS
Digitalization of agriculture bring controllable industrial production and computer-aided design ideas into agriculture, NURBS curves and surfaces is described freedom of widely popular technology, CAD systems are widely used. Method can be easily applied to generate curves, surfaces with NURBS. In this paper, we have developed model of cotton organs using NURBS surface, present a introduction ...
متن کاملOptimization Design of I-Type Plastic Extrusion Die Based on Flow Balance
With the I-type plastic extrusion die for example, the advantages and disadvantages between the traditional design method and optimization design method were compared. The design was studied via finite element numeric analysis combined with optimization, whose objective was the equal average flow velocity of each sub-field of profile cross section at extrusion die. And the optimization design w...
