Abstract: Purpose of this paper is that authors report a new die structure and an adjustment method in comparison with the traditional shim adjustment. The authors developed a multipoint supported die and suggest supporting cell relocation as adjustment method. The authors evaluate distribution of imposed load on supporting cells and their deformation at the slide-stroke-end. They also evaluate product accuracy with a 3D scanner. To make load distribution and height of the cells uniform in a time, we must find some goal function for adjustment to satisfy the above two goals, or develop the dedicated structure and procedure to adjust them in a time. The suggested multipoint support system and supporting cell relocation is one of the methods to adjust them in a time. Numerical simulation should be applied to reduce time of trial blows in future. Suggested die structure is hopeful to carry out more accurate large deep drawings. More and more accurate deep drawings are required today and the suggested die structure will contribute to it.
