Abstract

The invention discloses a manufacturing method of a special-shaped metal air pipe. The manufacturing method comprises the following steps of establishing an air pipe model of the air pipe to be manufactured in three-dimensional software according to a design drawing, and segmenting the air pipe model; establishing a coordinate system in the three-dimensional software so as to obtain the coordinates of each segmented section, and manufacturing an inner flange and outer flange of each segmented section according to the coordinates of each segmented section; simulating the established coordinate system to manufacture a coordinate frame, and positioning and fixing the outer flanges to the coordinate frame according to the coordinates of the segmented sections corresponding to the outer flanges; adopting a manual positioning and covering method to obtain an expanded pattern of each section of air pipe and then carrying out blanking, or using the three-dimensional software to unfold the model of each section of air pipe and then carrying out discharging; and fixing the inner flanges to the corresponding outer flanges, and then performing forming and group welding on all material plates, and dismounting each inner flange and outer flange and the coordinate frame after welding to obtain the air pipe to be manufactured. According to the manufacturing method, the workload of loading is small, results are accurate, the manufactured air pipe is small in joint seam, and the attractiveness is high.

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...
