Embodiment
With reference to the accompanying drawings and detailed description, the utility model is described further.
As shown in figure 1, a kind of cone embeds guide colume type dilatation mold, for wheel rim expansion process, including cope plate 1, under
Template 2, symmetrically arranged upper mold core installing plate 9 and lower mold core installing plate 10, upper mold core 11, lower mold core 12, upper cone 5 and lower cone
Body 6, up and down core rod installing plate be separately fixed on bolster, up and down core rod be separately fixed above and below on core rod installing plate, on
Lower cone 6 be embedded in respectively above and below core rod installing plate middle part in, in addition, the dilatation mold be additionally provided with upper cone fixing nut 3,
Lower cone fixing nut 4, upper core bar 8, embedded guide pillar 7, the upper cone fixing nut 3 are installed with the middle part of upper mold core installing plate 9
The first groove in, upper core bar 8 is provided with upper cone fixing nut 3, the top of upper core bar 8 and upper cone 5 is connected, described
Lower cone fixing nut 4 is installed with the second groove of lower mold core installing plate 10, and being located at lower cone in the lower end of lower cone 6 fixes
In nut 4, upper lower cone is connected by embedded guide pillar 7 with bolster, this embed guide pillar 7 can between upper lower cone on move down
It is dynamic.The width of first groove is down become narrow gradually from the top of upper mold core installing plate 9, and the width of the second groove is pacified from lower mold core
The top of dress plate 10 down gradually broadens.
Further to improve the concentricity of bolster, a groove, upper cone fixing nut are provided with the middle part of cope plate 1
3 upper end is installed with the groove, and its lower end is located in the first groove 15.In addition a groove is provided with the middle part of lower template 2, under
The upper end of cone fixing nut 4 is located in the second groove 16, and its lower end is installed with the groove.Using such a mode, it may be such that
Lower cone fixing nut in the even closer laminating of bolster, so be brought into close contact lower cone with above and below ensureing core rod it is concentric
Degree.
In addition, upper mold core installing plate 9 is connected with cope plate 1 by bolt 14.Cope plate 1 and upper cone fixing nut
Between 3 and/or between upper core bar 8 and upper cone 5 and/or between lower cone fixing nut 4 and lower template 2 and/or upper mold core 11
It is connected, can also leads between upper mold core installing plate 9 and/or by screw 13 between lower mold core 12 and lower mold core installing plate 10
Cross other manner to be connected, be not limited.
In addition, gap 18, i.e. lower cone 6 are left between lower cone 6 and lower cone fixing nut 4 with activity space,
The gap 18 can ensure above and below core rod concentricity, even if there is slight shift at upper and lower mould center, embedded guide pillar 7 can also look for center
Just, because center is all the time in upper mould, lower mould is subordinate relation.
On the basis of the utility model template above 1 and the center of lower template 2, upper cone fixing nut 3 is closely matched somebody with somebody with cope plate 1
The center of fixed cope plate 1 is closed, upper core bar 8 is fitted close with upper cone 5 embedded guide pillar 7 fixing upper cone center, upper core bar 8
Further fixed upper cone center is fitted close between upper cone fixing nut 3, passes through upper cone fixing nut 3, upper cone 5
Screw thread between upper core bar 8 coordinates and is oriented to and coordinates, so as to realize the rising of upper cone 5, decline and fixed upper cone center.
Similarly, lower cone 6 is coordinated with lower cone fixing nut 4 using screw thread, and is left between lower cone 6 and lower cone fixing nut 4
Gap 18, the cooperation also for gap coordinate, by the screw thread coordinate and gap coordinate can not only realize the liftable of lower cone 6 regulation but also
Leave guide space.During operation, a wheel rim 17 is directed to by the upper lower cone of the pressure progress of template 2 of cope plate 1 with one heart and expanded
Work.
Two key factors for constituting steel ring without inner tube quality are wheel rim, spoke, and the crucial quality of wheel rim is wheel rim
Overall circularity and mounting surface out-of-roundness.And ensure the overall circularity of wheel rim and the key of mounting surface out-of-roundness and be in dilatation mold
The concentricity of core rod up and down.The utility model is mainly improved to the upper lower cone in dilatation mold, and at the center of upper cone 5
Increase an embedded guide pillar 7 to realize the correcting to core rod up and down, and then fundamentally ensure the concentricity of upper and lower mould core rod, from
And reaching improves the target of the overall circularity of wheel rim 17 and mounting surface out-of-roundness.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, is not departing from the spirit and scope of the present utility model that appended claims are limited, in form and details
