Description

Spiral-pipe of Production-equipment

The present invention relates to a spiral tube manufacturing apparatus, and more specifically, it is possible to manufacture a spiral tube using a thin plate of about 2.3 to 6t used to manufacture a circular spiral tube used in air ducts, etc. 6 ~ 22 tons of conventional thick plate can also be used to manufacture spiral tube using a variety of thickness of the plate, when manufacturing the spiral tube using the thin plate, the plate transfer in the manufacturing process is a plurality of feed rollers By guiding by, the thin plate can be prevented from bending or bending, and relates to a spiral tube manufacturing apparatus in which the material cost of the plate due to breakage is reduced.

In general, spiral ducts and pipes are made of galvanized steel (GI, HGI), galvalume pipe, color steel, AL JACKET PIPE, copper, tin, stainless steel (SUS), and are more economical than rectangular ducts. The excellent ribs on the outside of the straight tube provide high strength, long life, and simple contact and mounting, making construction easy.

In addition, the internal friction loss is low, the efficiency of leakage and leakage is excellent, and the production length is freely adjusted so that it can be produced on-site and the joint of lockseam part is excellent, so the air conditioning duct, double insulation pipe AL JACKET PIPE, excellent housing construction pipe It is widely used in road, vertical and horizontal drainage pipes, gutters for drip trays, hollow pipes, oil pipes, and industrial plant pipes.

In addition, the spiral tube is supplied by twisting the plate-like material in a screw type to complete the spiral tube by taking a form in which the spiral portion is connected to the spiral portion by hooking.

There is provided a molding apparatus for manufacturing a spiral pipe bonded by using a single screw extruder in the process of melt-kneading waste plastic and filler (ie fly ash).

In particular, the single-screw extruder is difficult to distribute and disperse due to its characteristics, so that the filler is mixed in one place and slips, and as a result, a change in the input amount and the discharge amount occurs, resulting in a constant and stable profile. Due to the difficulty in molding, difficulties and poor molding are frequently caused in the pipe production process.

Although the spiral pipes produced by the spiral pipe forming apparatus provided in Korean Patent Nos. 1999-0064617 and 1999-024148 have superior stiffness coefficients compared to conventional products, the most important raw materials and fillers in the molding process are known. According to the result of a flat test which tests the deformation of the pipe inner diameter by applying a constant external pressure depending on the kneading state, the pipe is broken and cracked due to the separation phenomenon of the raw material and the material. In addition, since the pipe itself has a weight of 2.5 to 3 times as compared to the existing double-walled sewer pipe, construction difficulties appear in the construction site.
