冷沖壓一般是以金屬板料為原材料（也有采用金屬管料和金屬材料的），利用壓力機(jī)上的模具作往復(fù)運(yùn)動，在常溫下對金屬板料內(nèi)部產(chǎn)生變形的內(nèi)力。 Based on this, in this design39。s each part。s processing craft, has determined the reasonable processing craft。s processing technological requirement conforms to the level to enter mold39。 關(guān)鍵詞： 級進(jìn)模， Usb 接口 ,加工 工藝 II Abstract Abstract:This design was aims at the
