今天的汽車就是完美自動化製程的典範。小到螺絲，大到金屬板材，從生產的第一秒到最後的發動機性能測試——每一輛車的背後，都是由成千上萬個獨立步驟組成的連續生產線。隨著自動化技術的進步，產品品質也隨之提高。製程越安全可靠，維護和機器停機的運作成本就越低。
因此，做為一家與汽車產業領先企業合作的定制輸送系統製造商，對於 NSM Magnettechnik GmbH 這樣的公司來說，製程可靠性高是一個決定性的競爭優勢。在一種新型金屬板材堆垛系統中，專家們選用了氣缸/閥組合，它由單一閥 VUVG 和終端位置具有自調節式緩衝器 PPS 的標準氣缸 DSBC 組成。這種直接安裝解決方案採用 500 個這樣的氣缸，可確保精確緩衝和同步運動。
小變化，大影響
細節決定成敗——以金屬板材堆垛系統中的氣缸切換為例。如果要把這些原料製成精美的汽車蒙皮，比如車頂、車門、引擎蓋和行李箱蓋，您需要的不僅僅是一塊切割完美的原料。
放置和堆垛原料的製程也必須準確無誤。如果 500 個氣缸中的某一個將磁力皮帶運輸來的板材在錯誤的時間或方向上推入堆垛中，就會影響產品的品質。之前的系統使用手動調節式緩衝器 PPV 的氣缸 DNCB 來推送磁力運輸來的鈑金件。自從切換到具有自調節式緩衝器 PPS 的新型氣缸 DSBC 後，製程可靠性得到了顯著提高。
The synchronous adjustment of the 500 pneumatic cylinders in the NSM stacking system used to be anything but easy. With the outdated cylinders DNCB, the cushioning PPV had to be adjusted individually. For safety and to facilitate visual inspection, the adjusting screws were covered with sealing wax. Adjusting the cushioning of the 500 cylinders to make sure that it was absolutely synchronous was not only extremely time- and labour-intensive, but also lacking in precision compared with the new cylinders DSBC.
Thanks to the new self-adjusting cushioning PPS, each individual cylinder is always cushioned identically and advances completely in sync. This not only protects the blanks, but also reduces maintenance costs by up to 70 per cent and permanently reduces downtimes for the new system. These are significant advantages for NSM Magnettechnik in the competitive automotive industry.
