Abstract
The invention relates to an adhesive-free steel-plastic composite winding pipe and a manufacturing method thereof. The adhesive-free steel-plastic composite winding pipe is formed by compounding a plastic plate strip and a steel rib, wherein the plastic plate strip consists of a connector edge, a reinforced rib, a vertical rib and a plate wall, the plastic plate strip is compounded with the steel rib after being continuously wound to form a spiral plastic pipe, the steel rib is arranged between the vertical ribs of two adjacent plastic plate strips of the spiral plastic pipe, the part which is covered by the steel rib comprises the connector edge and the reinforced rib and is free from comprising the vertical ribs, the vertical ribs are heated to be softened, and the vertical ribs are pressed towards the side of the steel rib through a press wheel and are cooled. The adhesive-free steel-plastic composite winding pipe has the advantages that the steel rib is simple and convenient to embed, the resin adhesive is free from being thermally melted for binding, the combination of the steel rib and the strip is fir, the mechanical force on the spiral plastic pipe and the steel rib is small during the production process, and the damage is difficult to happen.
Description
Technical field
The present invention relates to a kind of entwining tube, particularly a kind of adhesive-free steel-plastic composite winding pipe and manufacture method thereof.
Background technique
The steel plastic composite wound pipe of present many plastic pipe manufacturer production adopts T type rib, childly buckles, box and wooden partition structure in sheet material design, method is to embed the steel rib behind the pipe crimping, buckles and box by the bonding son of thermoplastic resin glue class, reaches the enhancing effect.The design of T type rib is excessive in the strip material that this traditional steel plastic composite wound pipe and manufacture method adopt, the processing technology difficulty, fall easily partially, the steel rib is difficult for embedding, making steel plastic composite wound pipe often needs very big mechanical force booster action to realize, cause the damage of product easily, influence is used, the design of T type rib is too small, and the steel rib is deviate from easily.
The objective of the invention is to provide that a kind of to need not thermoplastic resin glue class bonding, the steel rib embeds easily, and it is firm that the steel rib combines with the strip material, simple adhesive-free steel-plastic composite winding pipe of manufacture method and corresponding method of manufacture.
For achieving the above object, technological scheme of the present invention is: adhesive-free steel-plastic composite winding pipe strip material, form by joint limit, T type rib, vertical rib and wooden partition four parts, the plastic board band is wound in Composite Steel rib behind the plastic spiral pipe continuously, the steel rib is put between the vertical rib of the adjacent plastic board band of plastic spiral pipe, wherein the part that covered of steel rib comprises joint limit and strengthening rib, does not comprise vertical rib, heat vertical rib to softening, adopt pinch roller that vertical rib is overwhelmed to steel rib side and cooling.It is simple and convenient to the invention has the advantages that the steel rib embeds, and it is firm that the steel rib combines with the strip material, and working process plastic spiral pipe and the suffered mechanical force of steel rib are little, is not easy to occur damaging phenomenon.

Fig. 2 is a plastic board belt structure schematic representation among the present invention;
Fig. 3 is that pinch roller overwhelms vertical rib schematic representation among the present invention.
Specific embodiments
As shown in Figure 1, adhesive-free steel-plastic composite winding pipe is composited by plastic board band 1 and steel rib 2, as shown in Figure 2, plastic board band 1 is made up of joint limit 3, T type rib 4, vertical rib 5 and wooden partition 6 four parts, plastic board band 1 is wound in Composite Steel rib 2 behind the plastic spiral pipe continuously, steel rib 2 is put between the vertical rib 5 of the adjacent plastic board band 1 of plastic spiral pipe, wherein the part that covered of steel rib 2 comprises joint limit 3 and T type rib 4, do not comprise vertical rib 5, as shown in Figure 3, heat vertical rib 5 to softening, adopt pinch roller that vertical rib 5 is overwhelmed to steel rib 2 sides and cooling.Adhesive-free steel-plastic composite winding pipe of the present invention and manufacture method thereof, whole manufacturing process need not that thermoplastic resin glue class is bonding, and the embedding of steel rib is convenient and simple, and it is firm that the steel rib combines with the strip material, do not need very big mechanical force auxiliary, are not easy to occur damaging phenomenon.
