Chengdu single-sided color steel phenolic board is used to make rectangular air duct. The dimension marked on the air duct refers to the dimension of the inner side of the air duct. Each air duct plate edge shall be cut into a 45 degree angle slope, and four air duct plates shall be combined to form a rectangular air duct. When 20 mm thick air duct plate is used, both sides of each air duct plate shall be 40 mm longer than the inner side of the air duct. One piece method, U-shaped two piece method, L-shaped two piece method and four piece method can be used for rectangular air duct combination. The setting out dimensions are different by using different combination methods. The setting out dimensions are calculated according to the combination method specified in the air duct manufacturing task list. Use steel ruler or steel tape to measure the calculated lofting dimension on the plate, and use square aluminum alloy guiding rule and brush to draw plate cutting, V-shaped groove line and 45 degree slope line on the plate.


The T-shaped rectangular duct consists of two straight rectangular ducts. Set out separately according to the method of setting out of rectangular straight air duct. The opening of the main pipe of Chengdu single-sided color steel phenolic board is measured at the design position, and the opening size is the side length of the corresponding branch pipe. Measure with a steel ruler, and use a brush and a square aluminum alloy guiding rule to draw the cutting line, V-shaped groove line and 45 degree slope line.


Before cutting, first check whether the setting out of the air duct plate meets the requirements of the air duct production task list, whether the marking is correct, and whether the plate is damaged; second check whether the installation of the cutter blade is firm, and whether the extension height of the blade meets the requirements. The protruding height of straight knife plane blade shall be able to cut off the trigger material without damaging the desk carpet; the protruding height of single knife plane blade and double knife plane blade shall be able to cut off the upper aluminum foil and core material without damaging the lower color steel plate; the distance between the two knives shall be about 2mm, and the left 45 ° single knife plane or the right 45 ° single knife plane shall be selected according to the cutting requirements, and the plate shall be placed on the workbench, and the square aluminum alloy shall be fixed in the proper position parallel with the ruler; the hand-held knife Press the datum line of the tool against the square aluminum alloy guiding rule, press the plate, align the datum line of the tool with the setting out line, push or pull the tool forward or backward, and cut the plate with the straight knife; cut the plate with the single knife; slot the plate with the double knives; after cutting the plate into a single air duct plate, number the air duct plate to prevent the air duct plate of different air ducts from getting wrong. For the plate on the bending surface, use the bending machine in the bending area Press groove.


Check whether the air duct panel meets the design requirements according to the air duct manufacturing task list; clean the powder on the cutting surface of Chengdu single-sided color steel phenolic board, remove the oil, water and dust, and then brush the adhesive on the cutting surface with a brush. When the adhesive is not sticky, glue the air duct panel according to the design requirements and flatten it with a scraper. For the parts that are difficult to be scraped flat, the wooden hammer can be used to gently hammer flat; check whether the bonding of the plate joint meets the quality standard, after meeting the quality requirements, bend the color steel plate 90 degrees, fix it with rivets, and the spacing between the rivets is not more than 10cm; after fixing, install the sealant into the sealant gun, clean the inner four corners of the air duct to be coated, evenly apply the sealant on the corner of the air duct with the sealant gun, and seal it After sealing, compact. Use steel ruler and angle ruler to check whether the air duct bonded meets the quality requirements.
