一、風管加工制作流程
風管是用于空氣輸送和分布的管道系統，它的種類眾多，不同風管的制作工藝流程有所不同，以常用的金屬風管為例，其加工制作工藝流程如下：1、風管尺寸的核定。根據設計要求、圖紙會審紀要，結合現場實測數據繪制風管加工草圖，并標明系統風量、風壓測定孔的位置。2、風管展開。依照風管施工圖（或放樣圖）把風管的表面形狀按實際的大小鋪在板料上；展開方法有三種即平行線展開法、放射線展開法和三角線展開法。3、板材剪切前必須進行下料復核，復核無誤后按劃線形狀進行剪切。4、板材下料后在壓口之前，必須用倒角機或剪刀進行倒角。5、板材的拼接。和圓形風管的閉合咬口可采用單咬口；矩形風管或配件的四角組合可采用轉角咬口、聯合角咬口、按扣式咬角；圓形彎管的組合可采用立咬口。6、畫好折方線，在折方機上折方。制作圓風管時，將咬口兩端拍成圓弧狀放在卷圓機上圈圓。7、折方或卷圓后的鋼板用合縫機或手工進行合縫。操作時，用力均勻，不宜過重。咬口縫結合應緊密，不得有脹裂和半咬口現象。8、風管的加固：風管一般可采用楞筋、立筋、角鋼、扁鋼、加固筋和管內支撐等形式加固。如果您有購買風管的需要，可以先來了解一下風管十大品牌。
