Description
Technical field
The present invention relates to a kind of gas delivery hose, especially a kind of steam transfer hose with wire, also relate to
Its special fixture for forming, belongs to technical field of hoses.
Background technology
According to the applicant understood, the existing steam transfer hose for vapour iron etc. often needs to transmit electric current or electricity simultaneously
Signal, therefore its typical structure is as depicted in figs. 1 and 2, mainly contains hose main body 1 and be attached to soft that section is discount vibram outlet shape
Wire 2 outside pipe main body.Wire 2 generally by an at least conductor cores 2-1, at least one layer of insulating barrier 2-2 of coating conductor core, with
And the insulating protective sleeve 2-3 being enclosed on outside insulating barrier is formed.In order that hose main body 1 and wire 2 form an entirety, steam
Delivery hose outermost layer wraps up braiding layer (not shown).
Practice have shown that during use, there is problems with above-mentioned prior art：1) because wire is without stretchable
Property, therefore pliability during hose bending is poor, wire is easily broken after alternating bending；2) hose main body is easily rolled over when bending
Flat, cause air-flow conveying not smooth, 3) the flexible pipe section after braiding layer parcel can not be formed and hose main body in wire attachment area
The complete circular arc that discount vibram outlet matches, therefore profile is not round and smooth, and feel is poor during gripping.
The content of the invention
It is an object of the invention to：In view of the above-mentioned problems of the prior art, being improved by process structure, propose a kind of
Bending freely, be hardly damaged, and ensure the steam transfer hose of insulation, while provide its special fixture for forming so that this
The steam transfer hose of invention has practicality.
In order to reach object above, steam transfer hose of the invention includes hose main body made of rubber-plastics material, described
The outer surface parcel braiding layer of hose main body, the cross-sectional shape of the hose main body is circle, and its internal circular surfaces has at least
Boss is axially extending radially at one, the middle part at the radial protrusion position has perforation, and being inserted in the perforation has
The wire of insulating barrier.
After structure using the present invention, because in hose main body in the aperture of radial direction raised central portion, therefore wire is inserted into
Layer constraint is no longer braided between each other, and flexible pipe pliability significantly improves, and bending freely, will not roll over flat, and wire when bending
Do not pulled, will not also be damaged even if alternating bending, and the wire being built in perforation is even without insulating protective sleeve,
Double insulation is formd with the insulating barrier of itself, it can be ensured that good insulating properties by perforation outer wall.Further, since flexible pipe master
Body section is unitary circular, therefore after parcel braiding layer, profile is carefully and neatly done, attractive in appearance, is easy to grip.
Making the special fixture for forming of steam transfer hose of the present invention includes having the framed of cylindrical hole, described framed
Top has the charging aperture of connection injection hole, baffle and rear mouth mold equipped with tubulose is fixed in the cylindrical hole, after described
Core rod after the fixed cylinder for forming annulus runner therewith in mouth mold, the front end of the baffle, which has to be formed with rear mouth mold, to be located at
The slant leading surface in bevel annular water conservancy diversion domain below charging aperture, the rear die core front end, which fixes rear end, has the preceding mould of deflection cone
Core, the preceding core rod are set with the preceding mouth mold being fixedly connected with rear mouth mold outside, the front end of the deflection cone extend with preceding mouth mold
Hole forms the main core section of hose main body section basic configuration, and the front end of the main core section extends to form the radial protrusion position
And its secondary core section of middle part perforation.
So, can once form internal circular surfaces has the flexible pipe at tape punching radial protrusion position, so as in interspersed wire
After bend freely, be hardly damaged, and ensure to insulate.If desired improve radiating effect, can also be axially extending radially it is convex
Play position and make several pores.
