Description

Technical Field

[0001] The invention relates to the technical field of pipeline processing, and in particular to an axially embedded winding structure wall pipeline forming device and a forming method thereof. Background Art

[0002] In order to prevent the spiral wound tube from cracking, we designed to add an axial snap-in structure (including protrusions and grooves) to the side wall of the profile, and improve the connection between adjacent turns of the spiral wound tube through the axial snap-in structure (traditionally it is just gluing); but this undoubtedly increases the difficulty of forming the spiral wound tube, and the axial snap-in structure needs to be snapped in during the winding process. For this reason, we have conducted a lot of research, such as CN202310042934.0, an axial snap-in anti-cracking plastic wound tube winding machine, which is designed to use the extrusion of the front and rear side pressure rollers to achieve the snap-in of the axial snap-in structure. This structure does not get good feedback during actual use, and the snap-in effect of the axial snap-in structure cannot be guaranteed. Summary of the invention

[0003] The present invention proposes an axially embedded winding structure wall pipe forming device and a forming method thereof, which requires little modification to the traditional forming device, can realize the embedding of the axially embedded structure, and has a good embedding effect.

[0004] The technical solution of the present invention: Axial clamping winding structure wall pipe forming equipment, the forming equipment includes a plurality of winding rollers, a glue injection nozzle, an extrusion wheel and / or an extrusion plate, each winding roller is surrounded by a circle to form an outer circle, a position on the outer circle is the profile entrance, the glue injection nozzle is installed at the profile entrance, and the extrusion wheel and / or the extrusion plate are installed behind the glue injection nozzle; a hot profile enters the outer circle from the profile entrance, advances along the outer circle spirally and is wound into a circle, and adjacent circles are connected by gluing and an axial clamping structure to form a tube blank; the glue injection nozzle is inserted between the first circle of hot profiles and the second circle of hot profiles, and the extrusion wheel and / or the extrusion plate are against the side of the first circle of hot profiles; The molding equipment also includes a plurality of hot air guns, each of which is installed at the entrance of the profile and facing the glue injection position.

[0005] The above technical solution is further improved, and the molding equipment also includes a rolling wheel, which is installed behind the extrusion wheel and / or the extrusion plate and abuts against the joint between the first circle of hot profiles and the second circle of hot profiles.

[0006] The above technical solution is further improved, and the forming equipment also includes a plurality of cooling nozzles, each of which is distributed around the tube billet and faces the tube billet; cooling water is sprayed on the tube billet through the cooling nozzles to cool the tube billet.

[0007] The above metal solution is further refined, the profile inlet is located at the top, the glue injection nozzle is vertically arranged, and the glue outlet is located at the rear side of the glue injection nozzle end; the glue injection is smoother.

[0008] A method for forming a pipe with an axially embedded winding structure wall adopts the above-mentioned pipe forming equipment with an axially embedded winding structure wall. In the method, a hot profile is fed into an outer circle from a profile inlet, and each winding roller rotates synchronously in the same direction, driving the profile to advance along the outer circle spiral and wind into a circle, and adjacent circles are glued and connected through an axially embedded structure to form a tube blank. After the tube blank is cooled, it becomes an axially embedded winding structure wall pipe; At the entrance of the profile, the glue injection nozzle injects glue between the first circle of hot profiles and the second circle of hot profiles, and the glue injection part is heated by a hot air gun during the glue injection.

[0009] The advantages of the present invention are reasonable design and ingenious conception. The hot air gun is used to heat the injected glue, 1) improving the state of the glue liquid, so that the glue liquid is in a molten state during injection, the glue discharge is smooth, and the glue is evenly distributed when squeezed, thereby ensuring the bonding effect between adjacent circles of the axially embedded winding structure wall pipe; 2) being able to soften the axially embedded structure to a certain extent, making it easier to embed, and the axially embedded structure can be easily realized by the front extrusion wheel and / or extrusion plate alone, and the embedding effect is good; 3) the cooling of the tube blank is generally achieved by water cooling, and it is inevitable that there will be splashing of water droplets, and there will be more or less water droplets at the injection point of the glue, which will mix into the glue liquid and inevitably affect the adhesion quality. The design of the hot air gun can solve this problem well. BRIEF DESCRIPTION OF THE DRAWINGS
