The oblique cutting die design for the large and high voltage generator rotor iron core sheet was set out, taking the consideration of the company equipment condition. Making use of a slide route of small tonnage high speed punch, the cutting die with oblique cutting and hack bottom discharge was designed, therefore, the cutting strength was declined to 8 t from 17. 6 t, that is, lowered by 53. 7%. The design mode of oblique cutting and the back bottom discharge made it easy to discharge waste. Using such technological plan, equipment investment can be lowered, the development of the new products can be speeded up and a new kind of technological plan with the novel ideas can be provided. It has been found that the technological plan is doable with the advantages of high precision, low cost and great efficiency. It can provide a reference for the designers to design the similar product dies.
