蚌埠機械制造為您介紹壓鑄生產(chǎn)模具損壞的原因以及預防措施一、造成壓鑄生產(chǎn)模具損壞的原因：在壓鑄生產(chǎn)中，模具損壞**常見的形式是裂紋、開裂。應力是導致模具損壞的主要原因。熱、機械、化學、操作沖擊都是產(chǎn)生應力之源，包括有機械應力和熱應力，應力產(chǎn)生于：（一）在模具加工制造過程中1、毛坯鍛造質(zhì)量問題。有些模具只生產(chǎn)了幾百件就出現(xiàn)裂紋，而且裂紋發(fā)展很快。有可能是鍛造時只保證了外型尺寸，而鋼材中的樹枝狀晶體、夾雜碳化物、縮孔、氣泡等疏松缺點沿加工方法被延伸拉長，形成流線，這種流線對以后的后面的淬火變形、開裂、使用過程中的脆裂、失效傾向影響極大。2、在車、銑、刨等終加工時產(chǎn)生的切削應力，這種應力可通過中間退火來消除。3、淬火鋼磨削時產(chǎn)生磨削應力，磨削時產(chǎn)生摩擦熱，產(chǎn)生軟化層、脫碳層，降低了熱疲勞強度，容易導致熱裂、早期裂紋。對h13鋼在精磨后，可采取加熱至510-570℃，以厚度每25mm保溫一小時進行消除應力退火。4、電火花加工產(chǎn)生應力。模具表面產(chǎn)生一層富集電極元素和電介質(zhì)元素的白亮層，又硬又脆，這一層本身會有裂紋，有應力。電火花加工時應采用高的頻率，使白亮層減到**小，必須進行拋光方法去除，并進行回火處理。中國臺灣T型螺母刀盒配件具有較好的熱導性：CBN的熱導性雖然趕不上金剛石。</p><div

立方氮化硼的主要性能特點如下：①高的硬度和耐磨性：CBN晶體結(jié)構(gòu)與金剛石相似，具有與金剛石相近的硬度和強度。PCBN特別適合于加工從前只能磨削的高硬度材料，能獲得較好的工件表面質(zhì)量。②具有很高的熱穩(wěn)定性：CBN的耐熱性可達1400——1500℃，比金剛石的耐熱性(700——800℃)幾乎高l倍。PCBN刀架可用比硬質(zhì)合金刀架高3——5倍的速度高速切削高溫合金和淬硬鋼。③優(yōu)良的化學穩(wěn)定性：與鐵系材料到1200—1300℃時也不起化學作用，不會像金剛石那樣急劇磨損，這時它仍能保持硬質(zhì)合金的硬度；PCBN刀架適合于切削淬火鋼零件和冷硬鑄鐵，可廣泛應用于鑄鐵的高速切削。④具有較好的熱導性：CBN的熱導性雖然趕不上金剛石，但是在各類刀架材料中PCBN的熱導性僅次于金剛石，**高于高速鋼和硬質(zhì)合金⑤具有較低的摩擦系數(shù)：低的摩擦系數(shù)可導致切削時切削力減小，切削溫度降低，加工表面質(zhì)量提高。蚌埠瑞強精密機械制造有限公司在機械及行業(yè)設備這一領域傾注了無限的熱忱和激情，蚌埠瑞強精密機械一直以客戶為中心、為客戶創(chuàng)造價值的理念、以品質(zhì)、服務來贏得市場。

style="text-indent:25px">【熱裝式刀具夾頭】熱裝式刀具夾頭是基于熱脹冷縮原理，采用感應技術對夾頭進行加熱。通過一個感應線圈（有些加熱裝置采用高頻線圈）對夾頭上刀具需要插入的部位進行精確加熱，將刀具插入后，通過冷卻套對夾頭進行冷卻，刀具柄部周圍的夾頭部位遇冷收縮，即可將刀具夾緊，并提供能夠承受高扭矩的牢固夾持力。熱裝式刀具夾頭具有許多優(yōu)點，主要包括高徑跳精度（小于0.003mm）、高傳動扭矩和比較小巧的外形設計。在減振性能上，熱裝式夾頭則要遜于液壓式夾頭和多邊夾緊式夾頭。中國臺灣T型螺母刀盒配件</p><p
