〠Abstract 】 The main characteristics and application characteristics of the roll forging numerical simulation software are introduced. It is pointed out that the computer numerical simulation of the roll forging process must become an important early stage of the new product development of roll forging. The rapid development of China's auto industry has driven the prosperity of the forging industry, and the rising prices of raw materials and the increasingly fierce competition have forced manufacturers to continuously reduce costs. In order to shorten the new product design cycle and reduce costs, companies must actively research and adopt new technologies and processes. Forging simulation software, as a powerful tool for enterprises, can analyze and improve the forging process, minimize the consumption of raw materials, avoid defects, improve the metal structure of forgings, and greatly shorten the development cycle of new products. The thermal processing of metallic materials is a very complex high temperature, dynamic and transient process with poor process openness. When the blank is deformed in the mold between the rotating upper and lower rolls, there must be a front slip and a back shift (see figure). Therefore, the design of the roll forging die requires a lot of complicated calculations, mainly relying on the experience of the designer. VeraCAD software (see Figure 2) was developed jointly by ERATZ Engineering GmbH of Germany and DGN GmbH and SMS Eumuco GmbH for the design of roll forging machines. In 2001, he won the Gold Award for Best Forging Invention of International Forging Technology Association. Main features 2. Software and hardware requirements 3.

At present, roll forging is a relatively advanced plastic forming process widely used at home and abroad. It can be used as a blanking process before die forging, or it can be directly rolled into forgings, which has high production efficiency, material saving, and dimensional stability of forgings. Good metal flow line and high mold life. It is now widely used in modern automotive, tractor, power, aerospace and commodity manufacturing industries.

When installing VeraCAD software, you need Microsoft WI NDOWS95, WI NDOWS NT or higher operating system, 486 or higher processor, and 8 M or more (64 M recommended) memory.
Vera CAD can be combined with popular CAD systems like ProE/UG/CATI A/. VeraCAD first imports the 3D CAD forging geometry using standard interfaces, preparing the forging die or forging graphic data (with or without flash, symmetrical or curved), with Euklid, IGES, VDAFS, STL 4 Data types for data interfaces. VearCAD has almost no restrictions on the complexity of the forgings. After the design is completed, the mesh roll forging die pattern or the solid roll forging die pattern is derived. After importing the forging geometry, the graph shown in Figure 3 can be displayed in the CAD window. VeraCAD performs accurate volume calculations based on the 3D CAD geometry provided by the user, taking into account the raw material dimensions and taking into account the hot and cold state of the forging, to obtain a mass distribution map, and at the same time, the screening function can be used to increase the flash material or the unfilled area. material.
