Therefore, the energy consumption is reduced; the productiyieldvity can be improved; and the intensity and the durability of the tubular material can be ensured.
Description
Technical field
For making a band for steel lining reinforced plastic pipe, belong to tubing and manufacture field, be specifically related to a kind of for making the band of steel lining reinforced plastic pipe.
Background technique
Present stage, for the production of tubing, is mostly the tubing that a kind of mould can only be produced a kind of specification, produces like this power consumption greatly, has improved cost of production.People adopted solid profile spiral winding to make conveyance conduit afterwards, solved to a certain extent the problem of mfg. moulding die, but little, the easy leakage of the hoop rigidity that this type of tubing is thick, shock resistance and bending resistance be poor, be not durable, caused the waste of material, weight is larger simultaneously, is unfavorable for lifting and transportation.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of for making the band of steel lining reinforced plastic pipe, use this band to make tubing can to regulate arbitrarily the diameter of tubing, and intensity greatly, do not reveal, durable, weight is lighter in lifting and transportation simultaneously.
The utility model solves the technological scheme that its technical problem adopts: this is used for making the band of steel lining reinforced plastic pipe, it is characterized in that: by plastic board/belt and enhancing steel lining, formed, described plastic board/belt is banded concavo-convex hollow slab, the cross section of steel lining plastic board/belt is rectangular, cross section one side is provided with the projection that protrudes from long edge, opposite side setting groove corresponding thereto, in the hollow sandwich of plastic board/belt, be provided with and the deep trench that strengthens steel lining and adapt, the both sides of deep trench are provided with groove, plastic closure is fastened in groove, and enhancing steel lining is sealed in deep trench.
The deep trench cross section arranging in the hollow sandwich of described plastic board/belt is " U " type, and strengthening steel lining is that cross section is the banded steel bar of " U " type.
The projection of described plastic board/belt cross section one side is calabash shaped termination, and the groove of opposite side is the calabash shaped nest groove matching with convex shape.
Tubing is formed by this plastic board/belt spiral winding with steel lining, during making, plastic board/belt, enhancing steel lining and plastic closure are put into extrusion press in order successively, at chimeric position, smear adhesive/sealant, start extrusion press, by strengthening steel lining and plastic closure, be pressed into respectively successively in deep trench and groove corresponding on plastic board/belt extruding all-in-one-piece steel lining plastic board/belt; Steel lining plastic board/belt after extrusion modling passed examination is put into spiral winding machine, set pipe diameter parameter, at chimeric position, smear adhesive/sealant, start spiral winding machine, carry out spiral winding, during spiral winding, the projection of plastic board/belt one side embeds in the groove of adjacent opposite side and forms tubing, until be wound around complete.By helically-wound shaped tubing sharpened edge, finishing, makes finished product.
Compared with prior art, the beneficial effect that the utility model has is: plastic board/belt kind arranges enhancing steel lining, has improved rigidity, and intensity is large, more durable, produces pipe diameter size and can regulate as required production, reduces energy consumption, has improved production capacity.Do not changing on the basis of tubing boundary dimension, reducing the wall thickness of tubing, weight is lighter, is beneficial to lifting and transportation.
Accompanying drawing explanation
Fig. 1 is the utility model steel lining plastic flitch band structure schematic diagram.
Fig. 2 is the utility model steel lining plastic board/belt A-A cross-sectional view.
Wherein: 1, plastic board/belt 2, enhancing steel lining 3, plastic closure 4, groove 5, projection.
Embodiment
Fig. 1 ~ 2nd, most preferred embodiment of the present utility model, is described further below in conjunction with 1 ~ 2 pair of the utility model of accompanying drawing.
With reference to accompanying drawing 1 ~ 2: this kind, for making the band of steel lining reinforced plastic pipe, formed by steel lining plastic board/belt spiral winding, and steel lining plastic board/belt main body is banded plastic board/belt 1.Plastic board/belt 1 cross section is the concavo-convex hollow slab of rectangular containing multiple hollow grids, on the long edge that one side is protruded, be set to lageniform protruding 5, the lageniform groove 4 that opposite side setting and protruding 5 shapes match, during spiral winding, the projection 5 of one side embeds in adjacent groove 4 and forms tubulose, and smear adhesive/sealant by tubing joint seal at chimeric position, guarantee not reveal.The neutral position in plastic board/belt 1 cross section arranges " U " moldeed depth groove, and the both sides of " U " moldeed depth groove arrange groove, and strengthening steel lining 2 is also the banded steel bar of " U " type for cross section.Plastic closure 3 is fastened in groove, and enhancing steel lining 2 is sealed in " U " moldeed depth groove, with this, has realized steel lining, has strengthened the rigidity of tubing.
Band spiral winding by this steel lining reinforced plastic pipe is made tubing, and pipe diameter can regulate arbitrarily as required, and concrete making method is as follows:
Step 1: be ready to qualified plastic board/belt 1 and plastic closure 3, and ready steel band be converted into the enhancing steel lining 2 that the cross section that meets size is " U " type.
Step 2: plastic board/belt 1, enhancing steel lining 2 and plastic closure 3 are put into extrusion press location in order successively, smear adhesive/sealant at the chimeric position of plastic closure 3.Start extrusion press, by strengthening steel lining 2 and plastic closure 3, be pressed into respectively successively in " U " moldeed depth groove and groove corresponding on plastic board/belt 1, adhesive/sealant is met plastics and is reacted, the plastics of melt surface one deck, plastic board/belt 1 and plastic closure 3 are bonded together, and seal up the steel lining plastic board/belt that enhancing steel lining 2 forms as one.
Step 3: the steel lining plastic board/belt after extrusion modling passed examination is put into spiral winding machine, set pipe diameter parameter, start spiral winding machine, carry out spiral winding.During spiral winding, strengthen steel lining 2 openings towards tube hub direction, at chimeric position, smear adhesive/sealant, adhesive/sealant is met plastics and is reacted, and the plastics of melt surface one deck, are tightly bonded in the projection of a side 5 in adjacent groove 4, until be wound around complete, tube forming.
Step 4: by helically-wound shaped tubing sharpened edge, finishing, makes finished product.
The above, it is only preferred embodiment of the present utility model, be not the restriction of the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
