Design Of A Small-Sized CNC Incremental Forming Machine

CNC incremental forming technology is a new type of dieless forming technology. It is in linewith modern manufacturing requirements of fast, low-cost, flexible and other technology trends. Thetechnology is used to meet the needs of small batch, many varieties and prototype making, and torealize the sheet metal parts fast, low-cost, flexible forming. In recent years, many scholars and insti-tutions have made a lot of research. As NC incremental forming technology support platform, the re-search and development CNC incremental forming machine tool are very important. A small metalCNC incremental forming machine is designed for incremental forming research and teaching in thispaper. The main tasks of this thesis are:First，by analyzing CNC incremental forming and investigating design documentation of suchmachine tool, the overall design plan of the machine tool is proposed in this paper. The machine toolis finally determined to be composed of engraving and milling machines and raising platform parts.Second, on the basis of the overall design plan, the various components of the machine havebeen designed in detail, especially the lift parts.Third, the three-dimensional model of the machine tool is created by using3D CAD software.And interference analysis and structure validation of machine tool structure are carried out. Solid-Works software is utilized to greatly shorten the design cycle and improve design efficiency.Fourth, the static and dynamic characteristics of the incremental forming machine main structureare analyzed by using the software of ANSYS Workbench. And the design is optimized according toresults of finite-element analysis.Fifth, CNC sheet metal incremental forming machine is completely assembled and tested run.During commissioning, the machine runs smoothly and the machined parts meet requirements, whichprove the feasibility of machine design.
