鍛打(da)件(jian)是(shi)(shi)指通(tong)過鍛造(zao)工(gong)(gong)(gong)(gong)藝(yi)(yi)(yi)(yi)加工(gong)(gong)(gong)(gong)而成的(de)(de)(de)金(jin)屬零部件(jian)，其(qi)報(bao)價(jia)(jia)(jia)(jia)一(yi)般(ban)考(kao)(kao)慮(lv)以下幾個方面：1.材料(liao)成本(ben)：鍛打(da)件(jian)的(de)(de)(de)材料(liao)成本(ben)是(shi)(shi)報(bao)價(jia)(jia)(jia)(jia)的(de)(de)(de)主要因素之一(yi)，一(yi)般(ban)根據(ju)所(suo)使用的(de)(de)(de)金(jin)屬材料(liao)的(de)(de)(de)種類(lei)、規格(ge)(ge)和(he)市場價(jia)(jia)(jia)(jia)格(ge)(ge)來(lai)計算。2.工(gong)(gong)(gong)(gong)藝(yi)(yi)(yi)(yi)成本(ben)：鍛打(da)件(jian)的(de)(de)(de)加工(gong)(gong)(gong)(gong)過程需要考(kao)(kao)慮(lv)設備的(de)(de)(de)使用費用、能耗以及人工(gong)(gong)(gong)(gong)成本(ben)等因素。一(yi)般(ban)來(lai)說(shuo)，較復雜(za)的(de)(de)(de)鍛造(zao)工(gong)(gong)(gong)(gong)藝(yi)(yi)(yi)(yi)會(hui)導致(zhi)較高(gao)的(de)(de)(de)工(gong)(gong)(gong)(gong)藝(yi)(yi)(yi)(yi)成本(ben)。3.加工(gong)(gong)(gong)(gong)難(nan)度：鍛打(da)件(jian)的(de)(de)(de)加工(gong)(gong)(gong)(gong)難(nan)度也(ye)會(hui)對(dui)報(bao)價(jia)(jia)(jia)(jia)產生(sheng)影(ying)響(xiang)。如需進(jin)行(xing)(xing)多(duo)道工(gong)(gong)(gong)(gong)序、特殊工(gong)(gong)(gong)(gong)藝(yi)(yi)(yi)(yi)或較高(gao)精度要求的(de)(de)(de)鍛打(da)件(jian)，其(qi)報(bao)價(jia)(jia)(jia)(jia)會(hui)相(xiang)對(dui)較高(gao)。4.訂單數(shu)量(liang)：訂單數(shu)量(liang)也(ye)是(shi)(shi)影(ying)響(xiang)報(bao)價(jia)(jia)(jia)(jia)的(de)(de)(de)重要因素。通(tong)常來(lai)說(shuo)，大批量(liang)訂單會(hui)得到更低的(de)(de)(de)單價(jia)(jia)(jia)(jia)，因為可以實現批量(liang)生(sheng)產和(he)優惠采購。5.市場競(jing)爭(zheng)：市場競(jing)爭(zheng)也(ye)會(hui)對(dui)鍛打(da)件(jian)的(de)(de)(de)報(bao)價(jia)(jia)(jia)(jia)產生(sheng)影(ying)響(xiang)。如果市場上存在較多(duo)的(de)(de)(de)供(gong)應商，價(jia)(jia)(jia)(jia)格(ge)(ge)競(jing)爭(zheng)會(hui)導致(zhi)報(bao)價(jia)(jia)(jia)(jia)相(xiang)對(dui)較低。綜(zong)(zong)上所(suo)述(shu)，青島方形鍛造(zao)件(jian)，鍛打(da)件(jian)的(de)(de)(de)報(bao)價(jia)(jia)(jia)(jia)是(shi)(shi)綜(zong)(zong)合考(kao)(kao)慮(lv)材料(liao)成本(ben)、工(gong)(gong)(gong)(gong)藝(yi)(yi)(yi)(yi)成本(ben)、加工(gong)(gong)(gong)(gong)難(nan)度、訂單數(shu)量(liang)和(he)市場競(jing)爭(zheng)等因素進(jin)行(xing)(xing)綜(zong)(zong)合評(ping)估的(de)(de)(de)結果。

異型鍛造(zao)(zao)件(jian)(jian)的(de)材(cai)(cai)質(zhi)選(xuan)(xuan)(xuan)(xuan)擇(ze)(ze)需(xu)要(yao)(yao)(yao)考慮(lv)(lv)(lv)其使用(yong)(yong)的(de)工況和性(xing)(xing)(xing)(xing)能(neng)(neng)要(yao)(yao)(yao)求(qiu)。通常情況下，選(xuan)(xuan)(xuan)(xuan)擇(ze)(ze)材(cai)(cai)質(zhi)需(xu)要(yao)(yao)(yao)考慮(lv)(lv)(lv)其耐(nai)磨(mo)性(xing)(xing)(xing)(xing)、性(xing)(xing)(xing)(xing)、可(ke)(ke)加(jia)工性(xing)(xing)(xing)(xing)、抗腐(fu)蝕性(xing)(xing)(xing)(xing)等(deng)因素(su)。對于使用(yong)(yong)條(tiao)件(jian)(jian)比較(jiao)(jiao)(jiao)惡劣的(de)場合(he)，如(ru)(ru)高溫、高壓(ya)、腐(fu)蝕性(xing)(xing)(xing)(xing)環境等(deng)，需(xu)要(yao)(yao)(yao)選(xuan)(xuan)(xuan)(xuan)擇(ze)(ze)耐(nai)磨(mo)性(xing)(xing)(xing)(xing)和性(xing)(xing)(xing)(xing)較(jiao)(jiao)(jiao)好(hao)的(de)材(cai)(cai)質(zhi)，如(ru)(ru)40Cr、35CrMo、20CrMnTi等(deng)合(he)金鋼(gang)(gang)。這些合(he)金鋼(gang)(gang)具有(you)較(jiao)(jiao)(jiao)高的(de)耐(nai)磨(mo)性(xing)(xing)(xing)(xing)和性(xing)(xing)(xing)(xing)能(neng)(neng)，可(ke)(ke)以(yi)滿足(zu)異型鍛造(zao)(zao)件(jian)(jian)的(de)使用(yong)(yong)要(yao)(yao)(yao)求(qiu)。對于腐(fu)蝕性(xing)(xing)(xing)(xing)環境，青(qing)島方形鍛造(zao)(zao)件(jian)(jian)廠家，可(ke)(ke)以(yi)選(xuan)(xuan)(xuan)(xuan)擇(ze)(ze)不銹(xiu)(xiu)(xiu)鋼(gang)(gang)材(cai)(cai)質(zhi)，如(ru)(ru)304、316、317L等(deng)不銹(xiu)(xiu)(xiu)鋼(gang)(gang)。這些不銹(xiu)(xiu)(xiu)鋼(gang)(gang)具有(you)良好(hao)的(de)耐(nai)腐(fu)蝕性(xing)(xing)(xing)(xing)能(neng)(neng)，可(ke)(ke)以(yi)防止(zhi)異型鍛造(zao)(zao)件(jian)(jian)在使用(yong)(yong)過程中受到腐(fu)蝕。在選(xuan)(xuan)(xuan)(xuan)擇(ze)(ze)可(ke)(ke)加(jia)工性(xing)(xing)(xing)(xing)材(cai)(cai)質(zhi)時，需(xu)要(yao)(yao)(yao)考慮(lv)(lv)(lv)其是(shi)否易于加(jia)工和制(zhi)造(zao)(zao)。例如(ru)(ru)，可(ke)(ke)以(yi)選(xuan)(xuan)(xuan)(xuan)擇(ze)(ze)20CrMnTi、1Cr13等(deng)易于加(jia)工的(de)材(cai)(cai)質(zhi)。這些材(cai)(cai)質(zhi)具有(you)較(jiao)(jiao)(jiao)低(di)的(de)切削加(jia)工難度，可(ke)(ke)以(yi)提高異型鍛造(zao)(zao)件(jian)(jian)的(de)制(zhi)造(zao)(zao)效率。另外，還需(xu)要(yao)(yao)(yao)考慮(lv)(lv)(lv)異型鍛造(zao)(zao)件(jian)(jian)的(de)使用(yong)(yong)工況和性(xing)(xing)(xing)(xing)能(neng)(neng)要(yao)(yao)(yao)求(qiu)，選(xuan)(xuan)(xuan)(xuan)擇(ze)(ze)適當的(de)材(cai)(cai)質(zhi)。例如(ru)(ru)，如(ru)(ru)果(guo)需(xu)要(yao)(yao)(yao)承受高壓(ya)載荷，可(ke)(ke)以(yi)選(xuan)(xuan)(xuan)(xuan)擇(ze)(ze)45#鋼(gang)(gang)或者(zhe)20CrMnTi鋼(gang)(gang)等(deng)材(cai)(cai)質(zhi)；如(ru)(ru)果(guo)需(xu)要(yao)(yao)(yao)承受沖擊載荷，可(ke)(ke)以(yi)選(xuan)(xuan)(xuan)(xuan)擇(ze)(ze)20CrMnTi、1Cr13等(deng)材(cai)(cai)質(zhi)。

自(zi)由鍛(duan)(duan)造(zao)(zao)件(jian)的(de)質量(liang)檢測(ce)(ce)主要依賴(lai)于目視檢查和測(ce)(ce)量(liang)工(gong)具(ju)。首先(xian)，青島方形鍛(duan)(duan)造(zao)(zao)件(jian)廠(chang)商，對于自(zi)由鍛(duan)(duan)造(zao)(zao)件(jian)的(de)外觀質量(liang)進行檢查，包括表面(mian)粗糙度、尺(chi)寸精度、形狀偏差(cha)等(deng)。其次，可以(yi)(yi)使(shi)用測(ce)(ce)量(liang)工(gong)具(ju)測(ce)(ce)量(liang)鍛(duan)(duan)件(jian)的(de)內部(bu)缺陷，青島方形鍛(duan)(duan)造(zao)(zao)件(jian)材質，如孔(kong)隙度、裂紋、分層等(deng)。此外，還可以(yi)(yi)使(shi)用金相(xiang)顯(xian)(xian)微(wei)(wei)鏡、光學顯(xian)(xian)微(wei)(wei)鏡等(deng)設備檢測(ce)(ce)鍛(duan)(duan)件(jian)的(de)顯(xian)(xian)微(wei)(wei)組織結構，以(yi)(yi)確保(bao)其內部(bu)質量(liang)。最后，可以(yi)(yi)對鍛(duan)(duan)件(jian)進行機(ji)械(xie)性能測(ce)(ce)試，如拉伸(shen)、壓(ya)縮、彎曲等(deng)，以(yi)(yi)確保(bao)其力學性能滿(man)足使(shi)用要求。
