鋁合金實(shí)心凸起結(jié)構(gòu)板鍛造成形工藝鋁合金實(shí)心凸起結(jié)構(gòu)板鍛造成形工藝Solid boss forming process of plate forging aluminium alloy 以鋁合金筒形件底部實(shí)心凸起成形為例，提出采用拉深-鐓擠板鍛造工藝成形中心實(shí)心凸起結(jié)構(gòu)，結(jié)合有限元模擬技術(shù)及工藝實(shí)驗(yàn)方法，比較傳統(tǒng)反擠壓工藝與板鍛造工藝成形實(shí)心凸起結(jié)構(gòu)的異同。結(jié)果表明：當(dāng)成形同一凸起高度時(shí)，板鍛造成形載荷比反擠壓成形載荷減小一倍左右。板鍛造成形過程中，底部分流面位置先內(nèi)移后趨于穩(wěn)定；而在反擠壓成形過程中，底部分流面位置先趨于穩(wěn)定后外移。凸模與板料上表面的單面潤滑可有效防止底部縮孔缺陷。 A new solid boss plate forging process named compression-drawing method was proposed to form the aluminum alloy sheet. The finite element method with DEFORM-2D and experiments were used to investigate the solid boss forming process. As a result, the forming load of back-extrusion is about two times higher than that of plate forging when the same height boss is acquired. During the solid boss forming, the location of separation flow surface first moves inner side and then remains stable as for plate forging, while it first remains stable and then moves outer side as for back extrusion. Besides, single lubrication between punch and upper side of workpiece can prevent the dimple defect. 全文下載：https://pan.baidu.com/s/1eSPII1k? 作為值得信賴的合作伙伴和高品質(zhì)金屬合金的半成品供應(yīng)商，通項(xiàng)公司擁有完善的服務(wù)體系和專業(yè)的團(tuán)隊(duì)。在同客戶交易的過程中，我們力求根據(jù)不同的應(yīng)用需求將我們的產(chǎn)品做到精益求精。針對當(dāng)前和未來的市場需求，通項(xiàng)公司致力于為客戶提供最佳的金屬材料解決方案。 TXCO has been a reliable partner and supplier of sophisticated and high-quality semi-finished products maed of alloys.
