As preferably, the top of described inner sleeve wall into a cone shape, the bottom of this inner sleeve wall is embedded on inner sleeve cylinder base, inner sleeve cylinder base becomes carnival hat shape, be the cylindrical of a depression in the middle part of it, edge, the lower end diameter of inner sleeve cylinder base is greater than the diameter of inner sleeve wall, is also provided with in the center of this inner sleeve cylinder base the bolt hole that runs through inner sleeve cylinder base.
Further, the internal diameter of described outer sleeve is slightly larger than the external diameter of inner sleeve wall, and its semidiameter is determined by the gross thickness of sebific duct and plug, and outer sleeve wall becomes stepped, is also provided with the friction line being beneficial to increasing friction force in the lower end outside face of outer sleeve wall.
Further, described gland is arranged on the below of inner sleeve cylinder base, and this gland is made up of gland main body and set bolt.
As preferably, the upper end of described gland main body is cylindrical, and its height is cylindrical equal with the depression in the middle part of diameter and inner sleeve cylinder base.
As preferably, the middle position of described gland main body also offers the through hole running through whole gland main body, and this through hole becomes stepped, and the through hole internal diameter of upper end is less than the through hole internal diameter of lower end.
As preferably, described set bolt is arranged in the through hole of gland main body central authorities, and this set bolt becomes stepped, and its diameter and through hole internal diameter match, gland main body is all stretched out at the two ends up and down of set bolt, is also provided with screw thread in the upper end of set bolt simultaneously.
Compared with prior art, the utility model has following beneficial effect:
Inner sleeve is first socketed in core rod end by the utility model, then rubber tube blank is enclosed within mandrel outer surface, then outer sleeve to be socketed in outside sebific duct and its end and inner sleeve are offseted, thus can be good at avoiding sizing material to overflow in core rod end position, ensure that the flatness of sebific duct expanding position after curing, make the wall thickness of the expanding position of sebific duct more even, without the need to carrying out crop processing after simultaneously sebific duct sulfuration, reduce production difficulty, improve yield rate and production efficiency, better save the means of production;
As preferably, the utility model is also provided with gland, can be good at plug and sebific duct entirety to be fixed, simplify sulfidation by gland, better can utilize space simultaneously; The utility model structure is simple, easy to use, and processing is lower with production cost, can adapt to large batch of manufacture and usage.

Detailed description of the invention
Core thinking of the present utility model is, there is provided a kind of sebific duct expanding frock, avoid the spilling of sizing material, ensure that the flatness of expanding position, make the wall thickness of the expanding position of sebific duct more even, get the difficulty of pipe after reducing sulfuration, improve yield rate and production efficiency, better save the means of production.
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, 2, 3, the expanding frock of a kind of sebific duct, comprises plug, also comprises outer sleeve 1 and inner sleeve 2 that size and this plug match, is also provided with the gland 3 matched with the size of inner sleeve 2 simultaneously.Above-mentioned inner sleeve 2 is made up of inner sleeve wall 21 and inner sleeve cylinder base 22, and inner sleeve wall 21 and inner sleeve cylinder base 22 are solidified as a whole.
The top of described inner sleeve wall 21 into a cone shape, the bottom of this inner sleeve wall 21 is embedded on inner sleeve cylinder base 22, inner sleeve cylinder base 22 one-tenth carnival hat shapes, be the cylindrical of a depression in the middle part of it, edge, the lower end diameter of inner sleeve cylinder base 22 is greater than the diameter of inner sleeve wall 21, is also provided with in the center of this inner sleeve cylinder base 22 bolt hole that runs through inner sleeve cylinder base 22.
