Abstract

The invention discloses a method for manufacturing a special-shaped metal air duct, which comprises the following steps: establishing an air duct model of the air duct to be produced in three-dimensional software according to design drawings, and segmenting the air duct model; establishing in the three-dimensional software The coordinate system obtains the coordinates of each section section, and makes the inner flange and outer flange of each section section according to the coordinates of each section section; the coordinate system established by simulation makes the coordinate frame, and according to the section corresponding to the outer flange The coordinates of the cross-section fix the outer flange to the coordinate frame; use the manual positioning covering method to obtain the unfolded graphics of each section of the air duct before cutting, or use 3D software to unfold the model of each section of the air duct before cutting; After the flange is fixed in the corresponding outer flange, each material plate is formed and welded, and after the welding, the inner flange, outer flange and coordinate frame are removed to obtain the air duct to be manufactured. The manufacturing method of the invention has small calculation and stakeout workloads, accurate results, and the manufactured air ducts have small joints and high aesthetics.

Description

technical field [0001] The invention relates to the field of manufacturing metal air ducts, in particular to a method for manufacturing special-shaped metal air ducts. Background technique [0002] Most of the thin-walled and special-shaped air ducts are non-standard parts, the quantity is small, and the shapes are different. If the method of die-opening and stamping is used, the cost is too high. Therefore, the production method of ordinary air ducts is currently used to manufacture thin-walled and special-shaped metal air ducts. [0003] During production, the air duct to be produced is first segmented manually according to the design drawings, and then each segment of the air duct is staked out, calculated, unfolded, rolled and corrected on kraft paper one by one until the shape of the paper tube rolled out , The size is in line with the design drawings, and finally it is formally cut and produced according to the shape and size of the kraft paper. When setting out and c...
