The main functional modles of the system are data base, which is used for analyzing, searching, transferring and downloading the design data by customer, powder-metallurgy die’s calculating modle, which can run directly and normally on internet, and remote parametric design system for powder-metallurgy die,etc.
In the light of the technological properties of roll forging, the design of the technology, the design of die, the design and calculation of dressing dies for roll forging of the preliminary forming of connecting rod are described in an allaround way in this paper.
SCR interface technique which joins the high-level language and AutoCAD system and compiles interface and application programs. On this basis,it exploits the software system of designing,calculation and automatic drawing used in spiral bevel driven gears precision forging die.
In this paper, the piston rings with a calabash shape pressure distribution pattern are presented, as well as the design and calculation of their casting dies, A great deal of calculation has been done with the aid of computer, and the pressure patterns of such piston rings are given in the paper.
The deformation and flow of metal in the process of roll forging are much different from those of ordinary die forging, So are the design of its technology, preliminary forming dies and dressing dies. In the light of the technological properties of roll forging, the design of the technology, the design of die, the design and calculation of dressing dies for roll forging of the preliminary forming of connecting rod are described in an allaround way in this paper.
