style="text-indent:25px">康弘機械冷拔方式：生產(chǎn)高精度冷拔管──液壓缸體與傳統(tǒng)的切削工藝比較，具有以下特點：（1）生產(chǎn)效率高：用傳統(tǒng)的方法生產(chǎn)一根內(nèi)徑420毫米，12米長的缸筒需154小時，用冷拔方法生產(chǎn)只需4分鐘。（2）成品率高：由于鏜孔的滾壓頭兼起導向作用，在切削過程中，毛坯管由于自重產(chǎn)生撓度，致使?jié)L壓頭和鏜刀走偏，造成廢品。成品率只能達到60%左右，而用冷拔方法生產(chǎn)，成品率可達95%以上。（3）金屬利用率高：用傳統(tǒng)的鏜孔方法制造缸體，金屬利用率只有50-70%。用拉拔方法生產(chǎn)時，金屬不但不被切削成鐵末，反而可以得到30%的延伸，金屬利用率可達95%。（4）能改善成品管金屬的機械性能：用拉拔方法生產(chǎn)，使毛坯得到30%以上的塑性變形，新鄉(xiāng)冷拔六角鋼，由于加工硬化而使成品管金屬的強度限大為提高。一般在成品管內(nèi)層強度限提高達60%。高精度冷拔管是用無縫熱軋鋼管、直縫焊管為坯料，經(jīng)過化學處理后在**冷拔機上，通過特種變形原理設計的模具進行拉拔，生產(chǎn)出高精度管。其尺寸精度達H10～H8，直線度達0.35～0.5mm/m，表面粗糙度達Ra1，新鄉(xiāng)冷拔六角鋼，新鄉(xiāng)冷拔六角鋼.6-0.4。冷拔鋼要按照正確步驟進行加工。新鄉(xiāng)冷拔六角鋼</p><div

冷軋鋼板的表面質(zhì)量、外觀、尺寸精度均優(yōu)于熱軋板，且其產(chǎn)品厚度右軋薄至0.18mm左右，因此深受廣大用戶青睞。以冷軋鋼卷為基板進行產(chǎn)品的深加工，成為高附加值產(chǎn)品。如電鍍鋅、熱鍍鋅、耐指紋電鍍鋅、彩涂鋼板卷及減振復合鋼板、PVC復膜鋼板等，使這些產(chǎn)品具有美觀、高抗腐蝕等優(yōu)良品質(zhì)，得到了廣泛應用。冷軋鋼卷經(jīng)退火后必須進行精整，包括切頭、尾、切邊、矯平、平整、重卷、或縱剪切板等。冷軋產(chǎn)品廣泛應用于汽車制造、家電產(chǎn)品、儀表開關、建筑、辦公家具等行業(yè)。鋼板捆包后的每包重量為3~5噸。平整分卷重一般為3~10噸/卷。鋼卷內(nèi)徑610mm。

style="text-indent:25px">冷拔方鋼對拉模的基本要求有什么？拉模的工作部分應具有正確的端面形狀和精確的幾何尺寸，保證冷拔后的尺寸公差符合規(guī)定；拉模的工作部分應有光潔的表面，以保證冷拔方鋼有較高的表面光潔度；拉模要有足夠的強度，避免在拔制時因強度不足而破壞，或產(chǎn)生過大的彈性變形。制造冷拔拉模的材料，要求價格便宜，加工方便。拉模的選擇對所拔鋼材的幾何尺寸及拔制過程能否正常進行都起到關鍵的作用，所以應當充分重視。以上都是對拉模的模孔設計、材質(zhì)的選擇、合理的制造工藝等多個方面進行說明，冷拔方鋼的拉模選配應符合以上的要求。</p><p style="text-indent:25px">嚴格的純潔度要求。鋼的純潔度是指鋼中所含非金屬夾雜物的多少，純潔度越高，鋼中的非金屬夾雜物越少。軸承鋼中的氧化物、硅酸鹽等有害夾雜物是導致軸承早期疲勞剝落、顯著降低軸承壽命的主要原因。特別是脆性夾雜物危害很大，由于在加工過程中容易從金屬基體上剝落下來，嚴重影響軸承零件精加工后的表面質(zhì)量。因此，為了提高軸承的使用壽命和可靠性，必須降低冷拔圓鋼中夾雜物的含量。表面缺點包括裂紋、夾渣、毛刺、結(jié)疤、氧化皮等，內(nèi)部缺點包括縮孔、氣泡、白點、嚴重的疏松和偏析等。這些缺點對于軸承的加工、軸承的性能和壽命有很大的影響，在軸承材料標準中明確規(guī)定不允許出現(xiàn)這些缺點。康弘機械生產(chǎn)銷售多種規(guī)格的冷拔鋼產(chǎn)品。</p><div
