Description
Technical field
The present invention relates to a kind of production method of plastic composite pipe, particularly in composite pipe, play the manufacture method and the particular manufacturing craft thereof of 90 ° of elbow steel skeletons of humidification.
Background technology
At present, the application of various plastic composite pipes in market is more and more wider, steel skeleton in 90 ° of bend pipe tools of multiple tube is owing to exist the manufacturing process defective, cause 90 ° of inwall plastic layers in the elbow product to have and much do not reach standard-required, thereby cause product degradation or scrap, study carefully its because of, be because of its processing method.Existing steel skeleton processing method is as follows: earlier sheet material is pressed Fig. 1 blanking, dashed or bored the hole, the hypographous area 8 of projection is cut away; Roll bending becomes straight-tube shape again, and the school type beats glomeration to projection then, welds together removing the slit that stays behind the dash area, and the school type is zinc-plated antirust again; Put it into injection mo(u)lding in the mould at last, have inside and outside becoming certain plastics thickness, in the composite plastic pipe fitting of strengthening steel skeleton is arranged.This is a kind of traditional manual manipulation method, the problem that exists is that production efficiency is low, the surface of sphere error of moulding is bigger, steel skeleton inside and outside wall plastic layer is not easy to reach standard-required after the injection mo(u)lding, and steel skeleton sphere welding bead is more, knock the intensity that the steel plate attenuation has been weakened steel plate by hand during the school type, make 90 ° of elbow manufacturing costs uprise, and bulk strength descends.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art and a kind of the manual operations accurately manufacture method and particular manufacturing craft thereof of 90 ° of elbow steel skeletons of multiple tube of rapid shaping of both having need not is provided.
Problem of the present invention realizes by following technical scheme:
90 ° of elbow reinforcing bars of a kind of multiple tube manufacture method, elder generation is cut into steel plate the shape of roll bending 7 by corner dimension; With roll bending 7 be rolled into cylindrical shape and the butt joint weld, make the steel skeleton 2 of tubular; Put it in the die 1 again, punch 3 is inserted in the steel skeleton of having made 2, exerting pressure by depression bar 6 promotes punch 3, punch 3 and on scraping wings 5 steel skeleton 2 can be pressed in the die 1, after punch 3 is pressed onto the end, extract punch 3 out, take out steel skeleton 2; Then, above-mentioned two steel skeletons 2 that have one of eight spheres are welded into 90 ° of elbow steel skeletons; Described punch and bottom of female die are sphere.
A kind of particular manufacturing craft of making 90 ° of elbow steel skeletons of multiple tube, it is made up of die 1, punch 3 and depression bar 6, and described die bottom is a sphere, and the top joining part is cylindric; Described punch matches; Described punch spherical diameter is identical with the Internal Spherical Surface diameter of steel skeleton, and described die spherical diameter is identical with the spherical outside surface diameter of steel skeleton.
The particular manufacturing craft of 90 ° of elbow steel skeletons of above-mentioned manufacturing multiple tube, set up pull bar 4 and scraping wings 5, described scraping wings 5 is between punch and die, its center is a through hole, the aperture of through hole is less than the external diameter of steel skeleton, the outside at through hole is provided with connecting hole, by pull bar 4 scraping wings is connected on the die.
The particular manufacturing craft of 90 ° of elbow steel skeletons of above-mentioned manufacturing multiple tube, the monolateral gap between described punch, the die is greater than steel skeleton steel plate gauge 0.2-0.6mm.
Used particular manufacturing craft among the present invention, the steel skeleton sphere adopts one-shot forming, has therefore improved production efficiency, and the surface of sphere error of batch moulding is little, and solder joint is few, and intensity is big.The elbow steel skeleton that the present invention makes can be used for having inside and outside anticorrosion and mesolow place that compressive resistance is had relatively high expectations after injection mo(u)lding is plastic composite pipe.The present invention has improved the efficient and the quality of making 90 ° of elbow steel skeletons, because the steel skeleton sphere is by the male and female mold compression molding, parameter consistency is good, after the injection mo(u)lding, ectonexine plastics wall thickness is comparatively even, thereby has improved the yield rate of pipe fitting, reduce cost, and guaranteed the intensity of pipe fitting.

Each label is among the figure: die 1, steel skeleton 2, punch 3, pull bar 4, scraping wings 5, depression bar 6, roll bending 7, dash area are the plate 8 that cuts.
The specific embodiment
With reference to Fig. 1～Fig. 6, the processing method of 90 ° of elbow steel skeletons of multiple tube is as follows:
Steel plate is cut into shape, punching or the boring of roll bending 7 by drawing.Hole side will be used for the plastics casting and make inside and outside wall form a complete integral body.With roll bending 7 be rolled into cylindrical shape and the butt joint weld, put into die 1, again punch 3 is inserted in the steel skeleton of having made 2.A hydraulic press or an oil cylinder are connected with depression bar 6, promote punch 3, by punch 3, scraping wings 5 steel skeleton 2 are pressed in the die 1, and the projection of steel skeleton 2 is with the moulding of concavo-convex mould sphere, and the cylindrical portions may of steel skeleton 2 has also obtained correction with the insertion of punch 3.After punch 3 is pressed onto the end, can extract punch out.Because steel skeleton 2 is wrapped on the punch, also together extract out with punch 3, just be stuck when in steel skeleton 2 is extracted out, running into the scraping wings 5 that connects by pull bar 4 and no longer extract out with punch 3.Punch 3 continues to rise to certain height, pulls down scraping wings 5 and takes out steel skeleton 2; As Fig. 4, shown in Figure 5, with revise good two have/steel skeleton 2 of a sphere is welded into 90 ° of elbow steel skeletons of multiple tube.
Particular manufacturing craft of the present invention is made up of die 1, punch 3, pull bar 4, scraping wings 5 and depression bar 6.Punch 3 is connected with depression bar 6, and die 1 is fixed on the workbench.The aperture of scraping wings 5 is less than the external diameter of steel skeleton.
