Abstract

The invention relates to an overall type steel belt vertical rib composite tube and a manufacturing method thereof. A vertical rib steel belt of the composite tube is provided with evenly-distributed meshes, meanwhile, the outer surface of the steel belt is coated with even adhesive resin, and the adhesive resin and the steel belt form a stable interpenetration adhesive structure; the steel belt coated with the adhesive resin is used for producing abnormal-shaped strips with vertical ribs, and the abnormal-shaped strips are used for producing the overall type steel belt vertical rib composite tube through spiral winding and welding; by means of the abnormal-shaped strips and tubular products which are produced in the manner, the stability of the overall structure can be guaranteed, and the service life of the tubular products is prolonged; and coating of the steel strips with the adhesive resin is achieved through a specific opening die, and the steel strips need to be heated to the required temperature before coating of the adhesive resin. By means of the overall type steel belt vertical rib composite tube and the manufacturing method, the problems that the steel belt vertical ribs and outer layer polyethylene are layered, and consequently the vertical ribs are toppled and fall, and a polyethylene protection layer is cracked are solved.

Example Embodiment

[0024] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings and specific implementations in the embodiments of the present invention. Obviously, The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0025] figure 1 The integral steel ribbed composite pipe of the present invention shown is composed of figure 2 The special-shaped strip shown is spiral wound and welded.
[0026] figure 2 Shown is a cross-sectional view of a special-shaped strip forming a pipe. The special-shaped strip is made of a steel strip 1 with a uniformly distributed perforated mesh as the reinforcing phase. The steel strip is coated with an adhesive resin layer 2, and the inner and outer layers are made of polyethylene layer 3. Antiseptic.
[0027] image 3 It is a steel strip coated with an adhesive resin layer 2 as a reinforcing rib.
[0028] Figure 4 It is a steel strip 1 with a uniformly-distributed mesh that forms an inter-transmission structure with the adhesive resin layer 2, which improves the structural stability of the pipe.
[0029] Figure 5 It is a schematic diagram of the structure used to coat the steel strip 1 with adhesive resin.
[0030] See attached figure 1 -Attached Figure 4 , This embodiment includes a pipe fitting base and an integral steel belt vertical rib spirally wound and welded on the outside of the pipe fitting base;
[0031] The integral steel strip vertical rib is a special-shaped strip, which includes a steel strip with uniformly distributed meshes, an adhesive resin layer 2 coated on the upper and lower outer surfaces of the steel strip 1, and a composite on the outer surface of the adhesive resin layer. Polyethylene layer 3;
[0032] The two ends of the steel belt are provided with lap edges, which are the lap sub side 4 on the right side and the lap female side 5 on the left side.
[0033] The method of the integral steel strip vertical rib composite pipe includes the following steps:
[0034] 1) The steel strip with uniformly distributed mesh is coated with bonding resin; the steel strip needs to be heated before coating with bonding resin. The heating adopts high-frequency heating or electric oven heating lamp method to meet the coating requirements ; The heated steel strip is coated with adhesive resin through a special die. The adhesive resin coated on the steel strip needs to be uniform, and the holes on the steel strip need to be filled so that the steel strip and the adhesive resin form an interpenetrating structure. Further improve structural stability.
[0035] 2) The steel belt vertical ribs coated with the adhesive resin and polyethylene obtained in step 1) are compounded to form a special-shaped strip; the steel strip coated with the adhesive resin is used to produce the special-shaped strip through a special die.
[0036] 3) The special-shaped strip obtained in step 2) is spirally wound and welded on the pipe fitting base to produce a composite pipe. The special-shaped strip is spirally wound and welded in a pipe forming cage to produce a composite pipe, and the produced pipe is cut to length according to needs.
[0037] Among them, step 2) and step 1) are two continuous processes. The steel strip coated with adhesive resin enters the special-shaped strip production die to continuously produce the strip required for winding the pipe.
[0038] Step 3) and step 2) are two continuous processes. The special-shaped strip enters the pipe forming cage, and the pipe is continuously produced by spiral winding and welding.
[0039] See attached figure 1 -Attached Figure 5 The specific operation process of this method is as follows: firstly, the steel strip 1 with uniformly distributed mesh that needs to be coated with adhesive resin is heated. The steel strip can be heated by high-frequency heating or electric oven heating; The steel strip 1 passes through the plastic coating die 6 at a constant speed, and the extruder 7 continuously bonds the resin, uniformly coats the adhesive resin on the surface of the steel strip, and uses the fluid pressure inside the die 6 to fill the steel strip with the adhesive resin After the steel strip exit mold 6 is cooled, the bonding resin and the steel strip 1 with uniformly distributed perforations form a whole.
[0040] The steel strip coated with the adhesive resin passes through the special-shaped strip production die at a constant speed to produce the required special-shaped strip, cool the strip, and the special-shaped strip enters the pipe winding cage at a uniform speed under the drive of the tractor. Spiral winding welding is carried out inside to produce the required pipes. The production method of the pipe can refer to CN2882985YH and CN102777710A.
[0041] The special-shaped strip and pipe produced by the invention have a stable structure, higher safety and longer service life.
[0042] The parts of the present invention that are not described in detail belong to the common knowledge of those skilled in the art.
[0043] The above description of the disclosed embodiments enables those skilled in the art to realize or use the invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined in this document can be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the creation of the present invention will not be limited to the embodiments shown in this article, but should conform to the widest scope consistent with the principles and novel features disclosed in this article.
