【文章內(nèi)容簡介】 The piercing die design. First, Analyzed the function request of the plank material, did preparation for the type that chooses to the die, is also convex, in the meantime, the material of punch and cavitydie had a to hurtle a characteristic of cut the piece behind, make sure the molding tool design parameter, choose other spare partses and unload to anticipate also convex, the calculation of the cave mold size had a there is spare parts to process a craft. Keywords: The piercing die punch cavitydie 1 緒 論 目前，我國沖壓技術與工業(yè)發(fā)達國家相比還相當?shù)穆浜?，主要原因是我國在沖壓基礎理論及成形工藝、模具標準化、模具設計 工藝及設備等方面與工業(yè)發(fā)達的國家尚有相當大的差距，導致我國模具在壽命、效率、加工精度、生產(chǎn)周期等方面與工業(yè)發(fā)達國家的模具相比差距相當大。 國內(nèi)模具的 現(xiàn)狀和 發(fā)展趨勢 國內(nèi)模具的 現(xiàn)狀 我國模具近年來發(fā)展很快，據(jù)不完全統(tǒng)
