Utility model content
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of inward turning flow turning instrument, and it has the advantages that structure is simple, service life is longer and machining accuracy is higher.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of inward turning flow turning instrument, and it comprises shell body, adjusting device, core retainer plate, core bar, retainer, cone post and positioning round table; Described positioning round table is two, and one of them is fixedly installed on the end of core bar, and another is movably arranged on core bar, is formed by concave surface pressing between described positioning round table; Described cone post is movably arranged on retainer and it abuts with by concave surface pressing and coordinates; Described core retainer plate is set in the outer peripheral face of core bar, and the end face of described core retainer plate abuts with the end face of the positioning round table be movably arranged on core bar and coordinates; Described adjusting device to be fixedly installed on shell body and with core retainer plate collaboration.
Described adjusting device comprises regulating sleeve, adjusting bolt and jacking block, and described regulating sleeve is fixed on shell body, and described adjusting bolt is screwed onto on regulating sleeve and its end and abuts with jacking block, described jacking block and core retainer plate collaboration.
The described structure by concave surface pressing be downward-sloping to inner side by outside, the structure of described cone post for by outside to being inclined upwardly in the middle part of it, the described concave surface pressing that is subject to is identical with the angle of inclination of boring post.
Described retainer is offered locating hole and detent, the two ends of described cone post are provided with positioning convex column, and described cone post is positioned at locating hole, and described positioning convex column is arranged in detent.
After adopting said structure, the utility model is compared to the prior art advantageously: structure of the present utility model is simple, the abutting by concave surface pressing that the end face of boring post can be formed with positioning round table, when processing, its stress point is just comparatively even like this, not only allows extended the service life of positioning round table and compares existing structure it effectively can also improve machining accuracy; The positioning round table be movably arranged on core bar can adjust it accordingly along with the adjustment of core retainer plate and be fixed on the spacing between the positioning round table on core bar, effectively can control the surplus of tube spinning like this, improves the convenience used.

Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, further illustrates below in conjunction with drawings and Examples to the utility model.
Embodiment, is shown in shown in Fig. 1 to Fig. 4: a kind of inward turning flow turning instrument, and it comprises shell body 10, adjusting device 20, core retainer plate 30, core bar 40, retainer 50, cone post 60 and positioning round table 70; Shell body 10 is for running through the hollow structure of both ends of the surface, and core retainer plate 30 is set in its hollow bulb.Positioning round table 70 is two, one of them is fixedly installed on the end of core bar 40, and another is movably arranged on core bar 40, and this vibrational power flow can facilitate the spacing between adjustment two positioning round table 70, so that the thinning surplus of the extruding adjusting pipe fitting, reaches good required precision.The path end face of two positioning round tables 70 is oppositely arranged, namely the structure by concave surface pressing 71 that two positioning round tables 70 are formed is downward-sloping to inner side by outside, can abut with cone post 60 by concave surface pressing 71 and coordinate, and the structure of boring post 60 for by outside to being inclined upwardly in the middle part of it, its angle of inclination is identical with being subject to the angle of inclination of concave surface pressing 71; Like this when working extruding, be contact between face and face by concave surface pressing 71 and cone post 60, compare the extruding of existing point and point, it not only can improve machining accuracy, and can also service life of effective elongate member.Retainer 50 is offered locating hole 51 and detent 52, the two ends of cone post 60 are provided with positioning convex column 61, and the activity of cone post 60 is positioned at locating hole 51, and positioning convex column 61 is arranged in detent 52; Locating hole 51 is extended, to carry out flow turning processing to pipe fitting in one end of cone post 60; And bore the movable setting of post 60 on locating hole 51, namely by the adjustment cone exposed portion of post 60 on locating hole 51, to reach the object controlling thinning surplus.Core retainer plate 30 is set in the outer peripheral face of core bar 40, the end face of core retainer plate 30 abuts with the end face of the positioning round table 70 be movably arranged on core bar 40 and coordinates, positioning round table 70 can adjust it accordingly along with the adjustment of core retainer plate 30 and be fixed on the spacing between the positioning round table 70 on core bar 40, at this moment meeting same with the cone post 60 abutted by concave surface pressing 71 adjust the thinning surplus of pipe fitting along with the change of positioning round table 70 spacing, so namely, effectively can control the surplus of tube spinning, improve the convenience used.Adjusting device 20 to be fixedly installed on shell body 10 and with core retainer plate 30 collaboration, described adjusting device comprises regulating sleeve 21, adjusting bolt 22 and jacking block, regulating sleeve 21 is fixed on shell body 10, and the inwall of regulating sleeve 21 has screw thread, and it can with the threaded portion threaded on core retainer plate 30; Have through screw from inside to outside at regulating sleeve 21, adjusting bolt 22 is screwed onto on the through screw of regulating sleeve 21, and the end of adjusting bolt 22 abuts with jacking block, and jacking block is positioned at the inside of regulating sleeve 21, itself and core retainer plate 30 collaboration; Like this after regulating the spacing between positioning round table 70, by screwing adjusting bolt 22 allow jacking block hold out against effect that core retainer plate 30 reaches stationary positioned, make operation more firm.
