Technical Problem
[0003]现有技术中的汽车纵梁连接板为L型,通过拉延模来完成拉延型面的成型,然后通过修边冲孔得到产品件,由于其为L型零件,在拉延时拉延深度深,拉延开裂,需要多次修边,增加了模具的工装开发及冲刺费用
Benefits of technology
[0021]本发明通过将第一固定块上设置有第一压料槽,第一压料板设置在第一压料槽内,第一压料板可上下滑动的设置在第一压料槽内;并使固定板与弧形板的第二端连接,弧形板的第一端与第一压料板的第一端抵接;固定板位于第一压料槽上顶端,弧形板位于第一压料槽内。在进行第一次冲压处理时,首先将第一压料板移动至与固定板平行,将胚料放置在第一压料板上,接着使第一上模镶块朝向第一下模镶板移动而作用在胚料上,此时第一上模镶块带动第一压料板移动至与弧形板相对应,完成对胚料的第一次冲压处理,接着将胚料放入第二次冲压模具中进行第二次冲压处理。本发明不需要对胚料进行拉延处理,避免了产品开裂而报废的问题,有效的降低了加工成本。
