5、Characteristics and Sheet Metal Forming1 The article overview Stamping is a kind of plastic forming process in which a part is produced by means of the plastic forming the material under the action of a die. Stamping is usually carried out under cold state, so it is also called stamping. Heat stamping is used only when the blank thickness is greater than 8100mm. The blank material for stamping is usually in the form of sheet or strip, and therefore it is also called sheet metal forming. Some n。

6、沖壓成形與板材沖壓 1 概述通過(guò)模具使板材產(chǎn)生塑性變形而獲得成品零件的一次成形工藝方法叫做沖壓。由于沖壓通常在冷態(tài)下進(jìn)行，因此也稱(chēng)為冷沖壓。只有當(dāng)板材厚度超過(guò) 8100mm 時(shí)，才采用熱沖壓。沖壓加工的原材料一般為板材或帶材，故也稱(chēng)板材沖壓。某些非金屬板材（如膠木板、云母片、石棉、皮革等）亦可采用沖壓成形工藝進(jìn)行加工。沖壓廣泛應(yīng)用于金屬制品各行業(yè)中，尤其在汽車(chē)、儀表、軍工、家用電器等工業(yè)中占有極其重要的地位。沖壓成形需研究工藝設(shè)備和模具三類(lèi)基本問(wèn)題。板材沖壓具有下列特點(diǎn)： （1）高的材料利用率。（2）可加工薄。
