1、劃線要據(jù)風(fēng)管的不同尺寸形狀和規(guī)格分別進(jìn)行，同時(shí)對(duì)一段風(fēng)管要完整進(jìn)行，防止劃線錯(cuò)孔和下料的多少有誤。板材剪切依據(jù)劃線的階段不同，分別進(jìn)行，同時(shí)必須進(jìn)行下料的復(fù)核，以免有誤。按劃線形狀用機(jī)械剪刀進(jìn)行剪切。

1. The marking should be carried out according to the different sizes, shapes, and specifications of the air duct, and a section of the air duct should be completed to prevent errors in marking, drilling, and cutting. The cutting of sheet metal is carried out separately according to the different stages of marking, and a review of the cutting process must be carried out to avoid errors. Use mechanical scissors to cut according to the marked shape.

2、剪切時(shí)，手嚴(yán)禁伸入機(jī)械壓板空隙中，上刀架不準(zhǔn)放置工具等物品，調(diào)整板料時(shí)，腳不能放在踏板機(jī)上，使用固定式震動(dòng)剪兩手要扶穩(wěn)鋼板，手離刀口不得小于5cm，用力均勻適當(dāng)。板材下料后在軋口之前，必須用倒角機(jī)或剪刀進(jìn)行倒角工作。金屬薄鋼板制作的風(fēng)管用咬口連接、鉚釘連接、焊接等不同方法。咬口寬度和留量要根據(jù)板材厚度而定。

2. When cutting, hands are strictly prohibited from reaching into the gaps of the mechanical pressure plate. Tools and other items are not allowed to be placed on the upper tool holder. When adjusting the plate material, feet should not be placed on the pedal machine. When using a fixed vibration shear, both hands should hold the steel plate firmly, and the hand should not be less than 5cm away from the cutting edge. The force should be evenly and appropriately applied. After cutting the sheet metal, it must be chamfered using a chamfering machine or scissors before rolling. The air ducts made of metal thin steel plates are connected using different methods such as biting, riveting, and welding. The width and allowance of the bite should be determined based on the thickness of the board.

3、焊接時(shí)必須焊縫均勻，無(wú)裂紋及加渣現(xiàn)象，鉚釘連接時(shí)，鉚釘中心先垂直于面板，鉚釘頭把板材壓緊，使板材密合并排列整齊、均勻。板材之間鉚接，一般中間不可以加墊料，設(shè)計(jì)規(guī)定時(shí)，遵循設(shè)計(jì)。咬口時(shí)手指據(jù)滾輪護(hù)殼不小于50mm，手不準(zhǔn)放在咬口機(jī)管道上扶穩(wěn)板料。

3. When welding, the weld seam must be uniform, without cracks or slag. When connecting with rivets, the center of the rivet should be perpendicular to the panel first, and the rivet head should press the plate tightly to ensure that the plate is tightly packed and arranged neatly and evenly. When riveting between sheets, it is generally not allowed to add padding in the middle. When designing, follow the design regulations. When biting, the fingers should not be less than 50mm against the roller protective shell, and hands should not be placed on the biting machine pipeline to stabilize the plate material.

4、咬口后的板料將畫好的折方線放在折方機(jī)上，置于下模的中心線，操作時(shí)，使機(jī)械上刀片與下模中心線重合，折成所需的角度。折方時(shí)應(yīng)相互配合并與折方機(jī)保持一定距離，以免被翻轉(zhuǎn)的鋼板或配件碰傷。

4. After biting, place the drawn folding line on the folding machine and place it on the centerline of the lower mold. During operation, make the mechanical upper blade coincide with the centerline of the lower mold and fold it to the desired angle. When folding, they should be matched with each other and kept at a certain distance from the folding machine to avoid being damaged by flipped steel plates or accessories.

5、制作員風(fēng)管時(shí)，將咬口兩端拍成圓弧狀放在卷圓機(jī)上卷圓。按風(fēng)管直徑規(guī)格適當(dāng)調(diào)整上、下輥間距，操作時(shí)，手不得直接推送鋼板。折方或卷圓后的鋼板用合口機(jī)或手工進(jìn)行縫合。操作時(shí)，用力均勻，不易過(guò)重。單、雙口確定咬合，無(wú)臟裂或半咬口現(xiàn)象。

5. When making the air duct, the two ends of the bite are flattened into an arc shape and placed on the rounding machine for rounding. Adjust the spacing between the upper and lower rollers according to the diameter specifications of the air duct. During operation, do not push the steel plate directly by hand. The folded or rolled steel plates are sewn together using a sewing machine or manually. When operating, apply force evenly and avoid being too heavy. Single or double bite confirmed bite, without any signs of dirty cracks or partial bite.

鍍鋅鋼板風(fēng)管是以鍍鋅鋼板為主要原材料，經(jīng)過(guò)咬口，機(jī)械加工成型，具有現(xiàn)場(chǎng)制作方便，同時(shí)具有可設(shè)計(jì)性，是傳統(tǒng)的通風(fēng)、 空調(diào) 用管道，同時(shí)隨著技術(shù)的發(fā)展，由以前的手工制作改變?yōu)楝F(xiàn)在得全部機(jī)械化化生產(chǎn)，具有效率高，加工尺寸等特點(diǎn)。

Galvanized steel sheet air duct is mainly made of galvanized steel sheet as the main raw material, which is formed through biting and mechanical processing. It has the advantages of convenient on-site production and designability. It is a traditional ventilation and air conditioning pipeline. With the development of technology, it has changed from manual production to fully mechanized production, with high efficiency and processing size.
