Abstract: |
The blanking method which get polyurethane instead of die,cutting mould instead of punch is researched in this article. Based on understanding the blanking process of polyurethane rubber,the design and calculation method of polyurethane rubber die and cutting mould are mastered. The good result of forming experiment and low cost prove that polyurethane pad blanking is deserved to promote. |
Key words: thin wall;polyurethane rubber;cutting mould |
