自(zi)由鍛件(jian)圖怎么制訂與繪制？

鍛(duan)(duan)件(jian)圖(tu)是(shi)編制鍛(duan)(duan)造工藝(yi)、設計工具(ju)、指導生產和驗收鍛(duan)(duan)件(jian)的主(zhu)要依(yi)據，也是(shi)與(yu)后續機(ji)械加(jia)工工藝(yi)有關的技(ji)術資料。它是(shi)在零件(jian)圖(tu)的基礎上考慮(lv)了加(jia)工余(yu)量、鍛(duan)(duan)件(jian)公(gong)差、鍛(duan)(duan)造余(yu)塊、檢(jian)驗試樣及工藝(yi)夾(jia)頭等(deng)因(yin)素繪制而成(cheng)。

加工余量

一般鍛(duan)件(jian)的尺(chi)寸(cun)精度和(he)表面(mian)粗(cu)糙度達(da)不到零(ling)件(jian)圖的要求，鍛(duan)件(jian)表面(mian)應留有供機械(xie)加(jia)(jia)工用的金屬層，這層金屬稱為機械(xie)加(jia)(jia)工余量(liang)(liang)（以下簡稱余量(liang)(liang)）。余量(liang)(liang)大小的確定(ding)與(yu)零(ling)件(jian)的形狀尺(chi)寸(cun)、加(jia)(jia)工精度、表面(mian)要求、鍛(duan)造加(jia)(jia)熱質量(liang)(liang)、設備工具精度和(he)操作(zuo)技術水平等有關。對于非加(jia)(jia)工面(mian)則(ze)無須加(jia)(jia)放余試。零(ling)件(jian)公稱尺(chi)寸(cun)加(jia)(jia)上余量(liang)(liang)。即為鍛(duan)件(jian)公稱尺(chi)寸(cun)。

鍛件的預成形坯：

預(yu)成(cheng)(cheng)形(xing)(xing)(xing)坯(pi)的(de)設計是(shi)根據鍛件的(de)重量、密(mi)度(du)、形(xing)(xing)(xing)狀和尺寸要(yao)求(qiu)，設計預(yu)成(cheng)(cheng)形(xing)(xing)(xing)坯(pi)的(de)密(mi)度(du)、形(xing)(xing)(xing)狀和尺寸的(de)。基(ji)本(ben)的(de)原則就是(shi)在鍛造(zao)時(shi)有利于預(yu)成(cheng)(cheng)形(xing)(xing)(xing)坯(pi)的(de)致密(mi)和充(chong)滿(man)模(mo)(mo)膛(tang)，同時(shi)在充(chong)滿(man)模(mo)(mo)膛(tang)前(qian)應(ying)盡可(ke)(ke)能使預(yu)成(cheng)(cheng)形(xing)(xing)(xing)坯(pi)有較大的(de)橫向塑性流(liu)動。但在充(chong)滿(man)模(mo)(mo)具型(xing)(xing)腔(qiang)前(qian)的(de)塑性變形(xing)(xing)(xing)量不能大于預(yu)成(cheng)(cheng)形(xing)(xing)(xing)坯(pi)塑性允許(xu)的(de)極限值。另外(wai)還必須考慮預(yu)成(cheng)(cheng)形(xing)(xing)(xing)坯(pi)在充(chong)滿(man)模(mo)(mo)具型(xing)(xing)腔(qiang)時(shi)，各部(bu)位的(de)應(ying)力狀態應(ying)盡可(ke)(ke)能處于三向壓應(ying)力狀態下，避免或減小拉應(ying)力狀態。

密(mi)(mi)度(du)是預(yu)成(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)坯(pi)(pi)(pi)的(de)(de)(de)基本(ben)參(can)數。根據預(yu)成(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)坯(pi)(pi)(pi)密(mi)(mi)度(du)及(ji)鍛(duan)件質量，求得預(yu)成(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)坯(pi)(pi)(pi)的(de)(de)(de)體積，然后(hou)根據預(yu)成(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)坯(pi)(pi)(pi)的(de)(de)(de)高徑比，分別確定預(yu)成(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)坯(pi)(pi)(pi)的(de)(de)(de)高度(du)及(ji)徑向尺(chi)寸。以此作為(wei)壓制模尺(chi)寸設計的(de)(de)(de)依據。粉末鍛(duan)件的(de)(de)(de)密(mi)(mi)度(du)主(zhu)要(yao)(yao)是由鍛(duan)造變形(xing)(xing)(xing)(xing)決定的(de)(de)(de)，一般與預(yu)成(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)坯(pi)(pi)(pi)密(mi)(mi)度(du)關系(xi)不(bu)大。預(yu)成(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)坯(pi)(pi)(pi)密(mi)(mi)度(du)選擇主(zhu)要(yao)(yao)考(kao)慮(lv)預(yu)成(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)坯(pi)(pi)(pi)要(yao)(yao)有足夠強度(du)，保(bao)證(zheng)在生產工(gong)序之(zhi)間的(de)(de)(de)傳輸過程不(bu)損(sun)壞，形(xing)(xing)(xing)(xing)狀完整(zheng)。為(wei)此一般冷壓制后(hou)的(de)(de)(de)預(yu)成(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)坯(pi)(pi)(pi)密(mi)(mi)度(du)為(wei)理論(lun)密(mi)(mi)度(du)的(de)(de)(de)80%左(zuo)右。

以下內(nei)容由(you)本公司為您提供(gong)，甘肅合金鋼(gang)鍛(duan)件，今天我們來分享合金鋼(gang)鍛(duan)件的(de)內(nei)容，希望(wang)對大家有所(suo)幫(bang)助：

金屬鍛造溫度(du)根據下(xia)列(lie)因素確定。

塑(su)和抗(kang)力圖 ?合(he)金的(de)塑(su)和抗(kang)力圖是對某一牌號的(de)合(he)金，通(tong)過熱拉伸(shen)、熱彎曲或熱鐓粗(cu)等不(bu)同(tong)試驗所測繪(hui)的(de)關于塑(su)性和變(bian)(bian)形(xing)抗(kang)力隨(sui)溫度(du)而(er)變(bian)(bian)化(hua)的(de)曲線圖。為了更(geng)好地符合(he)鍛(duan)造生產實(shi)際，常在動(dong)載設(she)備(bei)和靜載設(she)備(bei)上的(de)進行鐓粗(cu)實(shi)驗，這樣(yang)可以(yi)反映出(chu)變(bian)(bian)形(xing)溫度(du)對金屬的(de)塑(su)性指標和變(bian)(bian)形(xing)抗(kang)力的(de)影響，從而(er)定出(chu)適合(he)的(de)溫度(du)范圍(wei)。

再(zai)結晶圖(tu)(tu)(tu) ?合金的(de)再(zai)結晶圖(tu)(tu)(tu)是表示變形(xing)(xing)溫度(du)、變形(xing)(xing)程(cheng)度(du)與鍛件晶粒尺寸之間的(de)關系圖(tu)(tu)(tu)，它是通過實驗測繪的(de)。再(zai)結晶圖(tu)(tu)(tu)對(dui)(dui)后一道變形(xing)(xing)工序的(de)鍛造(zao)(zao)溫度(du)、變形(xing)(xing)程(cheng)度(du)具有重要的(de)參考(kao)價值。對(dui)(dui)于有晶粒度(du)要求的(de)鍛件，其鍛造(zao)(zao)溫度(du)常需根據再(zai)結晶圖(tu)(tu)(tu)來(lai)檢査和修正。

綜上(shang)所述，金屬鍛造溫度(du)(du)范(fan)圍以合(he)金的(de)平衡相(xiang)圖(tu)為基礎，再結合(he)塑(su)、抗力圖(tu)和再結晶圖(tu)，從金屬的(de)塑(su)性、變形抗力和鍛件質量三個(ge)方面進行(xing)綜合(he)分析(xi)，制訂出合(he)理的(de)鍛造溫度(du)(du)范(fan)圍。

以上就是關(guan)于合(he)金鋼(gang)鍛件(jian)的分(fen)享，希望(wang)能給大(da)家提供到幫(bang)助，了(le)解更(geng)多(duo)關(guan)于合(he)金鋼(gang)鍛件(jian)的問題歡迎來電咨(zi)詢，如您需要，竭誠(cheng)為您服(fu)務。
