（1）、模具工作零件加工過程中必須防止磨削燒傷零件表面現(xiàn)象,應嚴格控制磨削工藝條件和工藝方法(如砂輪硬度、粒度、冷卻液、進給量等參數(shù))； </p> <p> （2）、加工過程中應防止模具工作零件表面留有刀痕．夾層、裂紋、撞擊傷痕等宏觀缺點。這些缺點的存在會引起應力集中,成為斷裂的根源,造成模具早期失效； </p> <p> （3）、采用磨削、研磨和拋光等精加工和精細加工,獲得較小的表面粗糙度值,提高模具使用壽命。 </p> <p> <br /> 羅湖精密五金模具哪里好有高速鋼沖頭和鎢鋼沖頭等,而高速鋼是常用的材量。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

<br /> </p> <p> 所選材料應能使沖壓件在機器或部件中正常工作，并具有一定的使用壽命。為此，應根據(jù)沖壓件的使用條件，使所選材料滿足相應強度、剛度、韌性、耐蝕性和耐熱性等力方面的要求。 </p> <p> <br /> </p> <p> (2)按沖壓工藝要求合理選材 </p> <p> <br /> </p> <p> 對于任何一種沖壓件，所選的材料應能按照其沖壓工藝的要求，穩(wěn)定地成形出不至于開裂或起皺的合格產品，這是**基本也是**重要的選材要求。為此，可用以下方法合理選材。 </p> <p> <br /> </p> <p> ①試沖。根據(jù)以往的生產經驗及可能條件，選擇幾種基本能滿足沖壓件使用要求的板料進行試沖，***選擇沒有開裂或皺折的、其廢品率低的一種。這種方法結果比較直觀，但帶有較大的盲目性。 </p> <p> <br /> </p><p style="text-indent:25px">沖孔模的結構與一般落料模相似。但沖孔模有其自己的特點，特別是沖小孔模具，必須考慮凸模的強度和剛度，以及快速更換凸模的結構。在已成形零件側壁上沖孔時，要設計凸模水平運動方向的轉換機構楔的返回行程運動是靠橡皮或彈簧完成。斜楔的工作角度α以 40°～４５°為宜。40°的斜楔滑塊機構的機械效率比較高，45°時滑塊的移動距離與斜楔的行程相等。需較大沖裁力的沖孔件，α可采用 35°，以增大水平推力。此種結構凸模常對稱布置，**適宜壁部對稱孔的沖裁。鍍鈦加工廠家故揉捏出來的螺紋強度要比切削絲錐加工出來的螺紋高。</p><div style="width:100%;text-align: center;"><img
