壓瓦機(jī)是由放料、成型、后成型切割組成生產(chǎn)的機(jī)器，本程序主要介紹成型后通過模具進(jìn)行沖孔和切斷。PLC追剪沖切相對(duì)于原來的停切停沖方式大大提高了生產(chǎn)效率，相對(duì)于帶追剪功能的伺服可以更方便的設(shè)置版型。
二、工藝要求
程序可以設(shè)置兩種版型，如下圖所示。兩孔版型要求總長a可以設(shè)定，切口到孔的間距a1和a3可以在300mm到800mm范圍內(nèi)任意設(shè)定。三孔版型要求總長b可以設(shè)定，間距b1=b4、間距b2=b3,間距b1、b4可以在450mm到800mm范圍內(nèi)任意設(shè)定。設(shè)備絲杠長度550mm，切刀模具和沖孔模具間距277mm，切刀和沖孔完成一個(gè)沖孔或切斷動(dòng)作時(shí)間在0.6S，設(shè)備要求速度17m/min。

三、方案分析
該控制系統(tǒng)采用維控人機(jī)界面LEVI-700LK，PLC主機(jī)采用LX3VE-1412MT。
簡要方案如下：根據(jù)客戶要求速度17m/min,切刀或沖孔動(dòng)作時(shí)間0.6S，需要的同步區(qū)要大于170mm
再加上切刀和模具間距277mm，不能做成追剪的每次回原點(diǎn)，需要多段追剪后返回。
兩孔動(dòng)作順序，如下圖兩孔速度位移曲線。一段追剪切刀齊頭。第二段等待到達(dá)要求的沖孔位置啟動(dòng)沖孔。第三段由于前兩段已經(jīng)到達(dá)絲杠的大形成，需要返回一段距離。第四段到達(dá)第二個(gè)沖孔位置啟動(dòng)沖孔。第五段返回原點(diǎn)。兩孔動(dòng)作按照一段到第五段周期運(yùn)行。
三孔動(dòng)作順序，如下圖三孔速度位移曲線。一段追剪切刀齊頭，第二段到達(dá)一個(gè)沖孔位置啟動(dòng)沖孔，第三段返回一段距離，第四段達(dá)到第二個(gè)沖孔位置啟動(dòng)沖孔，第五段返回一段距離，第六段到達(dá)第三個(gè)沖孔位置啟動(dòng)沖孔，第七段返回原點(diǎn)。三孔動(dòng)作按照一段到第七段周期運(yùn)行。

四、程序簡要介紹
HMI程序：圖1為運(yùn)行的監(jiān)控畫面，圖2為版型的選擇設(shè)置，客戶不需要了解PLC程序內(nèi)部怎么設(shè)計(jì)只需要設(shè)置自己想要的版型就可以。
PLC程序：分為主程序，曲線生成，計(jì)算和動(dòng)作控制。
主程序部分程序，電子凸輪指令。

曲線生成主要包括兩孔版型生成曲線和三孔版型生成曲線?！鰐he upper display adopts 6-inch monochrome LCD panel or 10.4-inch TFT true color panel, which is applicable to medium and high-end models; With Chinese and English switching function, the graphical interface is friendly and intuitive, and the operation is convenient.
■ the injection speed curve can be stretched and translated freely, and the current actual injection curve can be displayed and compared, so that the operator can modify it in time.
■ the system has self-protection and alarm functions. In case of machine failure, it can automatically stop or reset according to the situation and display the current fault.
■ support Ethernet function and remote diagnosis function to realize network management. The system is the etching line of the common hole shadow mask, mainly including the uncoiling part, the etching cavity part, the first water washing part, the electrolytic stripping part, the final water washing part and the final drying and tearing part.
The rolled steel strip with photoresist on the surface is pulled at the uncoiled part and sent to the etching cavity. The cavity etching solution is FeC13, which reacts with the non photoresist part of the steel strip to form a slot. The function of the first water wash is to stop etching and uniformly and completely remove FeC13 on the surface of the shadow mask. The stripping part is used to peel the photoresist of the steel strip surface, and the stripping liquid is NaOH. Finally, NaOH and impurities on the steel strip surface are removed by water washing. The drying part dries the water on the surface of the steel strip to prevent rusting. After that, the steel strip enters the edge tearing machine to tear away the waste edges around the shadow mask. The etching cavity is the key part of the whole system, and its etching effect directly affects the product qualification rate. There are 6 cavities in the whole etching processThere are two pairs of upper and lower nozzles in each cavity, which arecontrolled by two motors respectively.
