摘　　要：高强钢制件生产是制约冲压的技术难题。为减少高强钢制件在实际生产中的冲压回弹量,文章介绍了9种高强钢制件回弹控制方法。使用增加拉延模工艺补充部位的2级台阶,拉延件直接到位与回弹工艺补偿值相结合的方法,使制件回弹量处于产品要求的公差范围之内,有效控制了高强钢制件的回弹。在实际工作中,9种回弹控制方法相结合,能有效控制高强钢制件回弹,降低制件报废率,提高产品质量。High strength steel part production is a difficult technical problem, which restricts stamping processing development. In order to reduce the spring back of high strength steel parts in the actual production of stamping parts, this paper introduces nine kinds of resilience controlling methods for high strength steel parts. Adding a 2-stage step on drawing die, drawing parts directly into place combined with spring back process compensation value, resilience amount is within tolerance range which is specified in specification, this method controls resilience of high strength steel parts effectively. In real application, adopting nine kinds of controlling methods can restrict resilience amount, reduce scrape rate and improve the product quality.
