如果裁切長(zhǎng)度大于兩倍切刀圓周長(zhǎng),運(yùn)行速度曲線如圖2所示;整個(gè)裁切循環(huán)從*個(gè)裁切點(diǎn)開始到第二個(gè)裁切點(diǎn)結(jié)束,重點(diǎn)分段說(shuō)明如下:
1. VEC-VBR控制系統(tǒng)隨時(shí)監(jiān)控進(jìn)料長(zhǎng)度與進(jìn)料速度并控制伺服馬達(dá)帶動(dòng)裁切刀輪,掌握正確的裁刀速度曲線。
2. 從*個(gè)裁切點(diǎn)開始 (裁刀方位角等于180度),當(dāng)時(shí)仍然在同步區(qū)域內(nèi),因此裁刀速度必須與進(jìn)料速度維持同步運(yùn)轉(zhuǎn)。
3. 當(dāng)裁切刀」離開同步區(qū)域后,裁刀速度曲線經(jīng)過(guò)控制系統(tǒng)精確的計(jì)算、控制,在降低到零速的同時(shí),裁刀方位角也必須剛好等于0度。
4. 當(dāng)進(jìn)料長(zhǎng)度累計(jì)到適當(dāng)長(zhǎng)度時(shí),裁切刀輪開始朝進(jìn)料速度目標(biāo)加速;而且裁刀速度曲線經(jīng)過(guò)控制系統(tǒng)精確的計(jì)算、控制,務(wù)求在裁刀速度上升到與進(jìn)料速度同步的同時(shí),裁切刀輪也恰好進(jìn)入同步區(qū)域。
6. 進(jìn)入同步區(qū)域之后,裁刀速度必須隨時(shí)與進(jìn)料速度維持同步運(yùn)轉(zhuǎn),直到第二個(gè)裁切點(diǎn)出現(xiàn),乃完成一次裁切循環(huán)。685B732U01
