Incremental Sheet Metal Forming

For the manufacture of panel parts, incremental sheet metal forming is significant in reality. This study put forward a method of incremental sheet metal forming: High-handed water jet with constant pressure and speed that caused by high pressure system acts on sheet metal and makes it out of shape, following transmutation superposition the requisite parts can be made. Based on this theory, a system of incremental sheet metal forming by using water jet is designed. At the same time, a forming experiment device is developed which is used to test the influence of water jet pressure, sheet metal thick, target distance to forming result. Finally, the optimized technological parameters of forming will be obtained. Within the work range, the higher pressure of water jet is, the more obvious forming result will be, and a great target distance will make forming result worse, besides sheet metal thick can make a difference of it. If sheet metal thick is invariable, there is interaction among pressure, target distance and feed velocity, so they influence forming result together.

The Relationship

A new method of sheet metal forming, water jet incremental sheet metal forming (WJISMF) is presented. We give the schematic illustration of WJISMF system, which includes high pressure system, NC machine, control system, water recycle system, and some attachments, and then the virtual prototype of the system is designed. To predict the whole deformation process, some simulations are carried out. Firstly, fluid structure interaction simulation for WJISMF is performed. The water jet is modeled and simulated with a computational fluid dynamics (CFD) approach, while for the material flow in the workpiece a finite element analysis (FEA) is used. Secondly, the relationship between the workpiece material deformation and nozzle diameter, and the relationship between deformation and water pressure are presented. Thirdly, the fluid structure interaction simulation model is simplified to the structure simulation model, by adopting shell 181 element and using a pressure acting on the workpiece directly instead of the CFD model. Finally, a simulation for forming a cone box is done using the simplified model. The simulation provides a powerful rationale for the practical application of WJISMF.

Five Axis

Water jet incremental sheet metal forming is the leading research topic in sheet metal forming industry, recently. In this work, a five-axis machine for water jet incremental sheet metal forming is designed and built, which is made up of four parts, namely linear motion unit, nozzle tilt and rotation unit, fixture and seal chamber. The nozzle tilt and rotation unit has two rotation degrees of freedom and the linear motion unit has three translational degrees of freedom. Then, two types of nozzles including L type nozzle and upright nozzle are designed and built. Finally, two different kinds of fixture are designed and built for common sheet metal forming and bellows expansion joints forming, respectively.

Water jet incremental sheet metal forming (WJISMF) is a new technology of sheet metal forming , a five-axis forming machine tool was designed ,with regard to research in this area is still in its infancy. Plenty of experiments was designed to study how to choose the reasonable molding process parameters. In addition, a spiral track instead of a contour track to solve the problem of surface depression was presented, and an example of processing was given to verify the advantages of the spiral track. Details of the use of UGCAM to generate spiral trajectory are descriped, the method is of universal significance. In addition, a vertical wall cylinder is formed through multi-step forming.
