A kind of crimping equipment of hose assembly
Technical field
The present invention relates to a kind of mounting equipment of hose assembly, especially relate to a kind of crimping equipment of hose assembly.
Background technology
In coal mine hydraulic supporting, usually transmit highly pressurised liquid with a lot of hose assemblies.Hose assembly comprises fuse, flexible pipe and overcoat, traditional assembly method is the rear end that first overcoat is enclosed within fuse, form an annular groove between the rear end of fuse and the overcoat, then the end with flexible pipe is inserted in the annular groove, with bales catch pipe machine overcoat is exerted pressure at last, its objective is an end of flexible pipe is fixed with fuse firmly, in bales catch pipe machine course of exerting pressure, can form at the outer wall of overcoat on the one hand and withhold trace, the endoporus of inner fuse is diminished.Because fuse is interior through diminishing, be equal in 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 crimping equipment that can improve the hose assembly in hose assembly service life.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of crimping equipment of hose assembly, comprise frame and hydraulic cylinder, described hydraulic cylinder is fixed on the described frame, pull bar and rose bit have been characterized by further comprising, be connected with drive plate on the driving shaft of described hydraulic cylinder, be provided with on the described drive plate for the fixing anchor clamps of fuse, the front end of fuse is fixed on the described anchor clamps, the center of described drive plate is provided with the first through hole, the center of described anchor clamps is provided with the second through hole, described the first through hole, the second through hole and fuse three are on the same axis, be provided with fixed head on the described frame, one end of described pull bar is fixed on the described fixed head, the other end of pull bar passes respectively the first through hole and the second through hole, described rose bit is fixed on the other end of described pull bar, described rose bit is positioned at the rear end of fuse, in use, under the driving of hydraulic cylinder, drive plate drives anchor clamps and fuse moves towards the rose bit direction together, and rose bit is pressed through the centre bore of fuse.
Be fixedly installed base plate on the described driving shaft, be connected by a plurality of axis of guides between described drive plate and the base plate, be provided with a plurality of pilot holes on the described fixed head, the described axis of guide passes described pilot hole.
Described fixed head is coupling on described frame, and described pull bar is horizontal by the angle of 15 degree~45 degree.
Described hydraulic cylinder is fixed on the described frame by bracing frame, and described bracing frame is coupling on described frame, interfixes by connecting rod between described fixed head and the described bracing frame.
Described fuse forms by three sections, be 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, the endoporus of the back segment of fuse is tapered, the diameter of this cone-shaped inner hole is by enlarging gradually near the interlude terminad, and 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 are R2, and the rear end external diameter of bullet is R1.
Compared with prior art, advantage of the present invention is that the rose bit position 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 annular groove, under the driving of hydraulic cylinder, drive plate drives anchor clamps and fuse moves towards the rose bit direction together, rose bit is pressed through the centre bore of fuse, adopt rose bit that the interlude of fuse and the endoporus of back segment are enlarged, the endoporus of fuse endoporus and flexible pipe is unified, and 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 technique of withholding, the aperture of fuse is dwindled, under the equal pressure condition of liquid, hose assembly by adopting process assembling of the present invention, compact structure can reduce original back pressure and flow loss, have longer service life, can not stay on the coat simultaneously and withhold trace, outward appearance is cleaner and tidier.
