shaped die
1.Paper aims at the theory problem of exact celerity machining design which is realized urgently in special shaped products, solves mathematics model of similar forming plastic stream, recurring to modern conformal mapping fruit, builds die mathematics model and optimized function equation of arc square product in precision extruding/drawing, establishes theory model for precision celerity shaped die of CAD/CAM integrative constitution.
6.Through the analysis on the side holes piercing technology for the U-shaped part, the structure of the piercing and word-pressing compound die for the U-shaped part was introduced. The main points for designing the punch for piercing the side holes in the U-shaped part were put forward.
7.Design of Glass Bead Profile in Extruding Die for the Plastic Special-Shaped Products
8.This article describes the design of extrusion die and selection of extrusion technology for P4A1483 4 type special shaped waveguide pipes of aluminium alloy and proposes that a special shaped waveguide pipe with a complex profile shall be manufactured by hot extrusion process with a combined die.
