數控機床作為一種柔性的、能的自動化機床,很好地解決了復雜、精密、小批量和多品種的零件加工問題。隨著數控機床設備在工業的廣泛應用,其運行的性也顯得愈發重要,的數控機床設備可以有效保護操作人員的人身,避免設備的頻繁故障,提高企業的生產力水平。
為了提高設備的等級,某動力公司位於的生產基地於2012 年啟動了設備防護改造工程,希望通過對機械加工設備的升級改造,避免由於設備功能的缺失或不完善可能導致的隱患,滿足長遠的 EHS目標,進一步提升企業的市場競爭優勢。
先讓們看看這家改造企業的背景:
該公司是一家多元化的動力管理公司,其生產的電力、流體動力和機械動力產品廣泛應用於建築、飛機、卡車、汽車、機械以及各種商業設施,年銷售額超過200億美元。此次改造的工廠是其位於的28個制造基地之一,主要生產各種液壓彎頭、接頭和管件等產品。
三重挑戰,如何個個擊破?
本次整改項目共涉及65臺套設備的機器改造,其中難度的是20臺 MAZAK數控機床的係統改造。
先,作為企業生產的核心設備, MAZAK數控機床的改造方案穩妥,只可成功,不可失敗。此外,MAZAK數控機床設備的使用率,設備每天工作16個小時,每小時開門20次,一年總計11.2 萬次的開門次數,這要求所用方案可靠和耐久,可以耐長期高負荷的運行條件。
令企業頭痛的是,原設備的PLC 係統代碼被保護,由於不能獲得原設備 PLC的代碼,改造時無法對設備做內部改變,但同時又要滿足數控係統機器的防護要求,新方案需要一個創新的設計思路。
總結來說,此次升級改造需要的不僅僅是係列產品,而是一個針對現有數控機床特點而設計的、完整的定制化解決方案。
好產品 , 更要有好的解決方案!
憑借在美同類項目的成功應用經驗,以及遍布各地的專業而快速的銷售和執行隊伍,羅克韋爾自動化針對工廠現有設備的具體情況,為其量身定制了係統升級方案。
改造前,數控機床設備的均採用單回路形式,改造目標是實現級別category 3。
先,羅克韋爾自動化的項目實施團隊反復多次和工廠多個部門討論,查找資料,吃透原機器結構和控制原理,熟悉機器的各種狀態,包括:設置、數控編程、運行(手動和自動)、小批次和大批量、維護和調試狀態等,新改造方案考慮上述各個方面。
在充分了解設備情況後,實施團隊嚴格遵循機器標準(ISO 13849 和 IEC 62061),增加防護係統並嵌入到現有係統中運行。
整體邏輯圖如圖1所示,新係統按照SIL 3標準來設計,新舊係統獨立而又並列運行,而且並行的輸入、串行的輸出將新係統和舊係統的措施有機結合起來,這種冗餘的結構設計是方案的一大亮點,保證了係統的穩定運行。
為保證改造方案的化,本次改造採用原型機試制和批量生產的方式。改造前,這些數控機床設備就在長期高負荷地運行,所以改造方案滿足苛刻的運行條件,不適宜一開始就批量改造,所以用19號機器先行改造,運行2個月後,針對效果提出進一步改進措施,而後全部用更新後的方案批量改造。
機器的耐久和穩定運行是本次改造的重要目標,為達成該目標,除了採用冗餘的係統架構外,實施團隊還採取了一係列的措施,包括:浮動推拉門、防震設計、通風防塵設計和備用回退選項等。
