Abstract
The invention discloses an assembling method of a hose assembly. A chambering taper is adopted to chamber a middle section of a core and an inner hole of a rear section, wherein the middle section of the core and the core wall of the rear section are deformed so that an annular groove between an outer sleeve and the core deforms so as to clamp and fix a hose. Compared with the traditional buckling process, the assembling method of the hose assembly provided by the invention has the advantages that the pore diameter of the core is not reduced; under the condition of same pressure of liquid, the hose assembly assembled by the process disclosed by the invention has a long service life; and meanwhile, a buckling trace is not formed on the outer sleeve and the appearance is neat.
Description
Technical field
The present invention relates to a kind of hose assembly, relate in particular to a kind of assembly method of hose assembly.
Background technology
In coal mine hydraulic supporting, transmit highly pressurised liquid with a lot of hose assemblies usually.Hose assembly comprises fuse, flexible pipe and overcoat; Traditional assembly method is the rear end that first overcoat is enclosed within fuse, forms an annular groove between the rear end of fuse and the overcoat, and the end with flexible pipe is inserted in the annular groove then; With bales catch pipe machine overcoat is exerted pressure at last; Its objective is an end of flexible pipe is fixed with fuse firmly that in bales catch pipe machine course of exerting pressure, the outer wall of meeting its external sleeve forms and withholds trace on the one hand; Can make the rear end distortion of inner fuse simultaneously, the back end inside diameter of fuse is diminished.Because fuse is interior through diminishing, be equal under the situation at the fluid pressure of the fuse of flowing through, can cause the fuse reduction in service life.
Summary of the invention
Technical problem to be solved by this invention provides a kind of assembly method that can improve the hose assembly in service life.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of assembly method of hose assembly is characterized in that concrete steps are following:
1) prepare a fuse and rose bit, fuse is formed by three sections, is respectively leading portion, interlude and back segment; The leading portion of fuse comprises that a diameter is the endoporus of R1; The interlude of fuse comprises that a diameter is the endoporus of R2, and the endoporus of the back segment of fuse is tapered, and the diameter of this cone-shaped inner hole is by enlarging gradually near the interlude terminad; The end diameter of cone-shaped inner hole is R3, RI >=R3>R2; The tapered body of rose bit, the front end external diameter of bullet is R2, the rear end external diameter of bullet is R1;
2) front end with rose bit arrives the rear end of inserting fuse;
3) fuse is fixed, put overcoat at fuse interlude and back segment place, form annular groove between fuse and the overcoat, the front end of flexible pipe inserts in the described annular groove;
4) rose bit is applied axial force; Rose bit is pulled out to leading portion from the back segment of fuse; The interlude of fuse and back segment produce deformation; The internal diameter of the interlude of fuse and back segment is RI after the deformation, and the annular groove after the distortion is fastened on flexible pipe between fuse and the overcoat, promptly gets the hose assembly that assembles.
Step 2) after in rose bit being inserted the rear end of fuse; Fuse and rose bit are enclosed within on the pulling force screw rod, load onto nut in the rear end of pulling force screw rod, nut is positioned at the rear portion of rose bit, and the diameter of nut is greater than the internal diameter of rose bit; In the step 4) pulling force screw rod is applied axial force, rose bit is pulled out to leading portion from the back segment of fuse.
Described bullet also comprises first cylinder and second cylinder; Described first cylinder is arranged on the front side of bullet; Described second cylinder is arranged on the rear side of bullet, and described first cylinder and bullet seamlessly transit, and the described bullet and second cylinder seamlessly transit; The described first cylindrical external diameter is R2, and the described second cylindrical external diameter is R1.
Compared with prior art, the invention has the advantages that and adopt rose bit that the interlude of fuse and the endoporus of back segment are enlarged that the core wall generation deformation of the interlude of fuse and back segment makes the annular groove deformation between overcoat and the fuse that hose clamp is fastened.Compare traditional technology of withholding, the aperture of fuse is dwindled, under the equal pressure condition of liquid, the hose assembly that is assembled by adopting process of the present invention has longer service life, can not stay on the coat simultaneously and withhold trace, and outward appearance is cleaner and tidier.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
A kind of assembly method of hose assembly is characterized in that concrete steps are following:
1) prepare a fuse 1 and rose bit 2, fuse 1 is formed by three sections, is respectively leading portion 11, interlude 12 and back segment 13; The leading portion 11 of fuse 1 comprises that a diameter is the endoporus of R1; The interlude 12 of fuse 1 comprises that a diameter is the endoporus of R2, and the endoporus of the back segment 13 of fuse 1 is tapered, and the diameter of this cone-shaped inner hole is by enlarging gradually near the interlude terminad; The end diameter of cone-shaped inner hole is R3, RI >=R3>R2; Rose bit 2 tapered bodies 21, the front end external diameter of bullet 21 is R2, the rear end external diameter of bullet 21 is R1;
2) elder generation is enclosed within the rear end of the front end insertion fuse 1 of rose bit 2 on the pulling force screw rod 3 with fuse 1 and rose bit 2, loads onto nut 4 in the rear end of pulling force screw rod 3, and nut 4 is positioned at the rear portion of rose bit 2, and the diameter of nut 4 is greater than the internal diameter of rose bit 2;
3) fuse 1 is fixed, put overcoat 5 at fuse 1 interlude 12 with back segment 13 places, form annular groove 6 between fuse 1 and the overcoat 5, the front end of flexible pipe 7 inserts in the annular groove 6;
4) on pulling force screw rod 3, apply axial force F; Rose bit 2 is pulled out to leading portion 11 from the back segment 13 of fuse 1; The interlude 12 of fuse 1 produces deformation with back segment 13; The internal diameter of the interlude 12 of fuse 1 and back segment 13 is RI after the deformation, and the annular groove 6 after the distortion is fastened on flexible pipe 7 between fuse 1 and the overcoat 5, promptly gets the hose assembly that assembles.
