電機定轉子沖片回轉事項

1、扭轉和回轉運動(dong)的實現過程

       級進模在高速沖載過程中，沖床的滑(hua)塊在下(xia)死點時，凸模和凹模之間是不允許有轉(zhuan)動現(xian)象的，所(suo)以扭轉(zhuan)機構、回轉(zhuan)機構的旋轉(zhuan)動作(zuo)必須是間斷運動，而且要與沖床滑(hua)塊的上下(xia)運動相協調。

        具體要求實現轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)(dong)過程是：在(zai)(zai)沖床(chuang)滑塊(kuai)每一次行(xing)程中，滑塊(kuai)在(zai)(zai)曲軸轉(zhuan)(zhuan)至240～60范(fan)圍(wei)(wei)內，回轉(zhuan)(zhuan)機構發(fa)生轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)(dong)，在(zai)(zai)其它角度范(fan)圍(wei)(wei)內處于靜止(zhi)狀態(tai)。其回轉(zhuan)(zhuan)范(fan)圍(wei)(wei)設定的方法：如采用回轉(zhuan)(zhuan)驅動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置(zhi)帶動(dong)(dong)(dong)(dong)(dong)的轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)(dong)，調(diao)整范(fan)圍(wei)(wei)就在(zai)(zai)該(gai)裝(zhuang)置(zhi)上進行(xing)設置(zhi)的；如采用電機帶動(dong)(dong)(dong)(dong)(dong)的轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)(dong)，就在(zai)(zai)電器控制器上進行(xing)設定或(huo)者通過感應接(jie)觸(chu)器進行(xing)調(diao)整接(jie)觸(chu)范(fan)圍(wei)(wei)；如采用機械式(shi)帶動(dong)(dong)(dong)(dong)(dong)的轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)(dong)，則通過杠(gang)桿轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)(dong)的范(fan)圍(wei)(wei)進行(xing)調(diao)整。電話：0576-82895678

2、回轉安全(quan)機構

       由于級進模在高速沖床上進行沖制，對于帶大角度回轉模具結構，如果定、轉子沖片落料外形不是圓形，而是方形或帶有齒形等異形的形狀時，為保證每次落料凹模回轉停留的位置正確無誤，確保落料凸模和凹模零件的安全，在級進模上必須設置有回轉安全機構。回轉安全機構的形式有：機械安全機構和電器安全機構。電話：0576-82895678
