specific Embodiment approach 1

[0007] Specific embodiment one: illustrate this embodiment in conjunction with Fig. 1, the production method of the manufacture steel mesh reinforced plastic composite pipe of this embodiment is completed by the following steps; After the inner plastic tube forming machine 2 is formed, the inner layer plastic tube blank 3 is cooled and shaped by the first vacuum cooling water tank 84; b, the outer wall of the inner layer plastic tube blank 3 is firstly wound horizontally by the first horizontal winding machine 4 steel, and then through the first longitudinal winding machine 6, the steel wires are longitudinally arranged to form the first layer of steel mesh, and the first layer of steel mesh and the inner plastic pipe blank 3 are sent into the first plastic pipe forming machine 9, and the first layer of steel mesh is used to form the first layer of steel mesh. The waste heat of the plastic pipe forming machine 9 heats the outer surface of the inner plastic pipe blank 3 to melt,...

specific Embodiment approach 2

[0008] Specific embodiment two: this embodiment is described in conjunction with Fig. 2, the difference between this embodiment and specific embodiment one is: this embodiment also adds b1 step between b and c steps, and described b1 step is: On the outer wall of the plastic composite tube blank 12 with a steel mesh structure, the steel material is continuously and horizontally wound by the second horizontal winding machine 14, and then the steel wires are longitudinally arranged by the second longitudinal winding machine 15 to form a second layer of steel mesh, with a layer of steel mesh. The plastic composite tube blank 12 with the net structure enters the second plastic tube forming machine 17 with the second layer of steel mesh, and the plastic composite tube blank 12 with one layer of steel mesh structure is heated by the waste heat of the second plastic tube forming machine 17. The outer surface is heated to melt, and the melting temperature is 120°C to 180°C. At the same...

specific Embodiment approach 3

[0009] Specific embodiment three: This embodiment is described in conjunction with FIG. 3 . The difference between this embodiment and specific embodiment one is: this embodiment also adds a b2 step between b1 and c steps, and the b2 step is: On the outer wall of the plastic composite tube blank 20 of the two-layer steel mesh structure, the steel material is continuously and horizontally wound by the third horizontal winding machine 21, and then the steel wires are longitudinally arranged by the third vertical winding machine 22 to form a third layer of steel mesh, with two The plastic composite pipe blank 20 of layer steel mesh structure enters in the third plastic pipe forming machine 24 with the third layer of steel mesh, and utilizes the waste heat of the third plastic pipe forming machine 24 to heat the plastic composite pipe with two layers of steel mesh structure. The outer surface of the billet 20 is heated to melt, and the melting temperature is 120°C to 180°C. At the ...

Abstract

The present invention is process and apparatus for producing steel net reinforced plastic composite pipe as one kind of steel structure reinforced plastic composite pipe. The process includes: extruding hot molten plastic into the inner plastic forming machine and cooling to obtain the inner plastic pipe blank layer, winding steel wire and arranging longitudinal wire onto the inner plastic pipe blank layer to form steel net, setting inside the first plastic pipe forming machine and extruding hot molten plastic into the first plastic pipe forming machine to form the composite plastic blank comprising one inner plastic pipe blank layer, one steel net layer and one outer plastic coating layer, and cutting to obtain the steel net reinforced plastic composite pipe. The equipment includes also one cooling water tank.

Description

technical field [0001] The invention relates to a production method and supporting equipment for manufacturing steel structure plastic composite pipes. Background technique [0002] At present, there are three main structural forms of steel structure plastic composite pipes, namely perforated steel belt reinforced plastic steel composite pipes, steel skeleton reinforced plastic steel composite pipes and steel wire reinforced plastic steel composite pipes. Hole mesh steel belt reinforced plastic-steel composite pipe is made of punching holes on steel plate, rolled and welded into a tubular shape, and then compounded with plastic inside and outside. If the surface of the steel is not well treated, the steel and plastic are easy to delaminate, and the amount of steel used is large and resistant to internal pressure. The ability is poor; the steel skeleton reinforced plastic-steel composite pipe is first welded with steel wire to form a mesh, and then composite plastic is formed...
