The utility model discloses a flaring fixture device for a corrugated pipe, which comprises a fixed base internally provided with a hollow cavity, a limited post and a flaring central spindle, wherein the fixed base comprises a fixed flange for bearing the limited post and an inner flaring post formed by extending along the downside of the fixed flange, an outwards flaring cone inner cavity is arranged on the end part of the inner wall of the inner flaring post, and the axial length of the cone inner cavity is consistent to the length of a pipe to be flared of the corrugated pipe; the limited post is arranged in a hollowing manner, one end of the limited post is supported above the fixed flange, and the other end of the limited post is provided with an outer flaring part; a ring gap is arranged between the periphery of the inner flaring post and the inner wall of the outer flaring part; the end part of the flaring central spindle is arranged in an outwards closing cone shape, the cone end of the flaring central spindle is arranged in the cone inner cavity, the cone end of the flaring central spindle is matched with the cone inner cavity; and in addition, the wall surface of the inner flaring post is provided with a cutting groove. Therefore, according to the flaring fixture device, the pipe mouth of the corrugated pipe can be flared, the production yield is increased, and the quality stability of products is effectively ensured.
Description
Technical field
The utility model relates to a kind of enlarging fitting device, is used for the enlarging operation of the bellows mouth of pipe.
Background technology
In the prior art, bellows is through shaped by fluid pressure, and the tolerance of its mouth of pipe has ± 0.2mm; And product often only needs the tolerance of 0-0.05mm, and for the bellows of mouth of pipe tolerance less than 0-0.05mm, also becomes qualified products for making it; Then need a kind of enlarging frock to carry out the enlarging operation; Otherwise this product will fall short of specifications, and need handle as substandard products.
The utility model content
The utility model is to the deficiency of prior art; A kind of bellow flare fitting device is provided; It can carry out enlarging operation to the bellows mouth of pipe, make that tolerance is operated through enlarging less than the bellows of 0-0.05mm after, also can become qualified products; Improve the production qualification rate of shaped by fluid pressure bellows, guarantee the quality stability that bellows is produced effectively.
For realizing above technical purpose, the utility model will be taked following technical scheme:
A kind of bellow flare fitting device; Establish firm banking, limited post and the enlarging mandrel of hollow cavity in comprising; Said firm banking comprises and is used to accept the holding flange of limited post and extends the interior enlarging post that forms along the holding flange top; And the conical internal cavity of outside enlarging is arranged in the inwall end of enlarging post in being somebody's turn to do, and the axial length of while conical internal cavity treats that with bellows the enlarging pipe range is consistent; The hollow setting of said limited post, and an end of limited post is supported on holding flange top, and the other end then is provided with outer expansion mouth, has the annular gap between the periphery of said interior enlarging post and the inwall of outer expansion mouth; The end of said enlarging mandrel is the taper setting of outside closing in; And the tapering point of enlarging mandrel places conical internal cavity, and the tapering point and the conical internal cavity of the mandrel of enlarging simultaneously are suitable, are provided with and the opposite end of enlarging mandrel tapering point is movable; In addition, the wall of said interior enlarging post is offered grooving.
The outer periphery of the inwall of said limited post and interior enlarging post is equipped with the annular containing cavity that is used to put bellows.
According to above technical scheme, can realize following beneficial effect:
Existing annular gap between the inwall of periphery and the outer expansion mouth of the utility model through interior enlarging post; The bellows mouth of pipe is placed this annular gap, through promoting the enlarging mandrel in the conical internal cavity, the bellows mouth of pipe is carried out the enlarging operation; Hence one can see that; The utility model can carry out enlarging operation to the bellows mouth of pipe, make that tolerance is operated through enlarging less than the bellows of 0-0.05mm after, also can become qualified products; Improve the production qualification rate of shaped by fluid pressure bellows, guarantee the quality stability that bellows is produced effectively.

The specific embodiment
Accompanying drawing discloses the structural representation of the related preferred embodiment of the utility model without limitation; Below will combine accompanying drawing that the technical scheme of the utility model at length is described.
As shown in Figure 1; The described bellow flare fitting device of the utility model; Establish firm banking, limited post and the enlarging mandrel of hollow cavity in comprising; Said firm banking comprises and is used to accept the holding flange of limited post and extends the interior enlarging post that forms along the holding flange top; And should in the inwall end of enlarging post be arranged to the conical internal cavity of outside enlarging, promptly the end that flushes of conical internal cavity and interior enlarging post is its big end, the axial length of while conical internal cavity treats that with bellows the enlarging pipe range is consistent; The hollow setting of said limited post, and an end of limited post is supported on holding flange top, and the other end then is provided with outer expansion mouth, has the annular gap between the periphery of said interior enlarging post and the inwall of outer expansion mouth; The end of said enlarging mandrel is the taper setting of outside closing in, and promptly the end of enlarging mandrel is the narrow end of its tapering point, and the tapering point of enlarging mandrel places conical internal cavity; The tapering point and the conical internal cavity of the mandrel of enlarging simultaneously are suitable; Be provided with and the opposite end of enlarging mandrel tapering point is movable, in addition, for enlarging post in making can carry out certain radiai adjustment; In order to avoid with bellows mouth of pipe extrusion damage, the utility model is offered the grooving that annular is uniformly distributed with more than two vertically with interior enlarging post.The outer periphery of the inwall of said limited post and interior enlarging post is equipped with the annular containing cavity that is used to put bellows.
During use; Adopt anchor clamps to grasp the holding flange of firm banking earlier; Then can earlier bellows be placed annular containing cavity; And make the mouth of pipe of bellows by chance be arranged in the annular gap, and perhaps bellows is socketed on the periphery of enlarging mandrel, can make the mouth of pipe of bellows by chance be arranged in the annular gap simultaneously; Adopt application of force equipment such as hammer to promote the enlarging mandrel then and move, realize the enlarging operation of the bellows mouth of pipe to the orientation of holding flange.
