所選材料應(yīng)能使沖壓件在機(jī)器或部件中正常工作，并具有一定的使用壽命。為此，應(yīng)根據(jù)沖壓件的使用條件，使所選材料滿足相應(yīng)強(qiáng)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(duì)于任何一種沖壓件，所選的材料應(yīng)能按照其沖壓工藝的要求，穩(wěn)定地成形出不至于開(kāi)裂或起皺的合格產(chǎn)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(chǎn)經(jīng)驗(yàn)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(jìn)行試沖，***選擇沒(méi)有開(kāi)裂或皺折的、其廢品率低的一種。這種方法結(jié)果比較直觀，但帶有較大的盲目性。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">沖孔模的結(jié)構(gòu)與一般落料模相似。但沖孔模有其自己的特點(diǎn)，特別是沖小孔模具，必須考慮凸模的強(qiáng)度和剛度，以及快速更換凸模的結(jié)構(gòu)。在已成形零件側(cè)壁上沖孔時(shí)，要設(shè)計(jì)凸模水平運(yùn)動(dòng)方向的轉(zhuǎn)換機(jī)構(gòu)楔的返回行程運(yùn)動(dòng)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(jī)構(gòu)的機(jī)械效率比較高，45°時(shí)滑塊的移動(dòng)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(jié)構(gòu)凸模常對(duì)稱布置，**適宜壁部對(duì)稱孔的沖裁。</p></p><br /><p>文章來(lái)源地址:
