Description

Technical Field

[0001] This utility model relates to a steam generating device, and more particularly to a corrugated perforated air duct. Background Technology

[0002] The air duct is a crucial component of a tenter frame, and its airflow effect directly impacts the quality of the fabric after tentering. Therefore, selecting the appropriate air duct for different types of textiles is particularly important. Commonly used air duct outlets on tenter frames include square and round holes, with square and round holes being the most widely used and suitable for most knitted and woven fabrics. However, they are less effective for long-staple and terry fabrics, as the airflow direction is not consistently uniform. Summary of the Invention

[0006] The technical problem to be solved by this utility model can also be further realized through the following technical solution: the duct body is a pipe with a square cross-section, which is composed of a top plate, a bottom plate and two side plates.

[0007] The technical problem to be solved by this utility model can also be further achieved through the following technical solution: the taper of the duct body is 1~9°.

[0009] Compared with the prior art, this utility model has a corrugated air duct and a wave hole formed between the two sides of the air outlet. The corrugated air duct can be formed by stamping.

[0017] The specific technical solutions of the present invention are further described below. To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, and to facilitate a better understanding of the present invention by those skilled in the art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments, and do not constitute a limitation on its rights. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] A corrugated duct includes a duct body that is tapered from an air inlet to an air outlet. One side of the duct body is designated as a main working surface, and an air outlet is provided on the main working surface. A top plate is provided on the main working surface, and the duct body has two side plates corresponding to the top plate. The air outlet is located between the top plate and the two side plates and is positioned along the length of the duct body. A corrugated air intake is installed at the air outlet, and the corrugated air intake is vertically positioned, forming a corrugated perforation between the corrugated air intake and the two sides of the air outlet.

[0019] The air inlet end of the duct body is equipped with a head frame, and the air outlet end of the duct body is equipped with a tail frame.

[0020] The duct body is a pipe with a square cross-section, composed of a top plate, a bottom plate, and two side plates.

[0021] The taper of the duct body is 1~9°.

[0022] The top plate has downward folded edges on both sides, and the two side plates have folded edges corresponding to the folded edges of the top plate, forming an air outlet duct at the folded edges. The corrugated air duct is vertically arranged in the aforementioned air outlet duct.

[0023] Due to the unique structure of the corrugated plate, corrugated ducts require bending on a bending machine. The longer the corrugated plate, the greater the bending workload. Based on the required dimensional specifications of the corrugated plate, including the crests, troughs, and wavelength, the basic outline of the corrugated plate bending die is drawn. Then, based on corrugated plate testing, the springback is calculated, the crest and trough dimensions of the die are corrected, and a suitable bending die for corrugated plate processing is determined.

[0024] The shaped molds are used on the bending machine for mass production, and the corrugated strip processing technology is adjusted according to the length requirements of the corrugated plate.

[0025] As shown in the figure, 1-upper mold, 2-lower mold, 3-plate, 4-corrugated plate, 5-main upper mold, 6-main lower mold, 7-additional upper mold, 8-additional lower mold, 9-left side plate, 10-top plate, 11-right side plate, 12-bottom plate, 13-head frame, 14-tail frame.

[0026] The corrugated sheet bending die is divided into an upper die 1 and a lower die 2, which are respectively installed on the pressure plate and the base of the bending machine. The contact surfaces of the upper die 1 and the lower die 2 are alternately fitted in a wave-like shape. Under the action of the upper die 1 and the lower die 2, the sheet 3 is bent into a corrugated sheet 4.

[0027] The bending die for corrugated sheets can be divided into a main upper die 5 and a main lower die 6. The corrugated sheets used for conventional corrugated air ducts can be bent and formed on the main upper die 5 and the main lower die 6. However, the corrugated strips used for corrugated air ducts on wide-width forming machines exceed the conventional size. It is necessary to attach an additional upper die 7 and an additional lower die 8 to the ends of the main upper die 5 and the main lower die 6 respectively in order to complete the bending and forming.

[0028] The corrugated plates 4, which are formed by bending molds, are fixed on both sides of the top plate 10 and alternately and symmetrically welded to the left side plate 9 and the right side plate 11. Then, the long folded edges of the left side plate 9 and the right side plate 11 are inserted into the bottom U-shaped grooves on both sides of the bottom plate 12 for interlocking and fixing. Finally, the beginning and end of the left side plate 9, the top plate 10, the right side plate 11, and the bottom plate 12 are riveted and fixed to the head frame 13 and the tail frame 14 to form the final corrugated hole air duct.
