Shown in Fig. 3 (a), in above-mentioned rail wheel maintaining body 6, be provided with and make rail wheel (interior wheel 2, foreign steamer 4) be crimped onto above-mentioned a plurality of rail wheel to load with the crimping structure 26 on each loading surface 10s (with reference to Fig. 2) of structure (nasal assembly of dashing forward) 10.As the form of crimping structure 26, for example, can adopt rail wheel (interior wheel 2, foreign steamer 4) to be loaded with structure (nasal assembly of dashing forward) 10 to each rail wheel push (pushing), and be crimped to the pressing method of each loading surface 10s; Perhaps rail wheel (interior wheel 2, foreign steamer 4) is loaded with structure (prominent nasal assembly) 10 attractions (attraction) to each rail wheel, be crimped onto sucking method on each loading surface 10s etc.

In Fig. 3 (a), represented that a plurality of rail wheels load the state that is arranged on the position of the interior wheel 2 of maintenance with structure (prominent nasal assembly) 10.In this embodiment; Example as crimping structure 26; Adopted pressing method; Crimping structure 26 in this pressing method (being also referred to as backer roll mechanism) has: the end face 2a (that is, across inner track wheel road face 2s be crimped on end face on each loading surface 10s and be the end face of an opposite side, wheel end face 2a in below being referred to as) that can internally take turns 2 hollow circular ring shape applies the pair of rolls 26r towards the pushing force of vertical lower.

The configuration of pair of rolls 26r subtend can be the center rotation with an imaginary rotating shaft (not shown), and be configured to be parallel to each other, and be separately positioned on the position, diametric both sides of the central shaft that runs through interior wheel 2 among the interior wheel end face 2a that is the hollow circular ring shape.In addition, in the stage at the position, both sides of wheel end face 2a, interior wheel 2 is in by a plurality of rail wheels and loads " interior wheel is with the being provided with " state that keeps with structure (prominent nasal assembly) 10 in pair of rolls 26r is arranged on.In this case, through after " foreign steamer is provided with switchings in the brake shoe-angle of rake " stated, with interior wheel 2 inwardly wheel push with brake shoe 44, interior wheel is set to and can uses brake shoe 44 to rotate as benchmark to take turns in this.

In order to realize such setting, crimping structure 26 has each roller 26r of supporting and makes it can rotate the pair of rolls support 26h of (for example rotating freely).Pair of rolls support 26h extends with the mode that is parallel to each other, and is supported with roller 26r respectively at its leading section.In addition, the base end part of pair of rolls support 26h connects (supporting) and in being used to that this roller support 26h is moved and pair of rolls 26r is arranged on, takes turns the travel mechanism (not shown) on the position, both sides of end face 2a.

The diameter (average diameter of the internal diameter of interior wheel end face 2a, external diameter, interior external diameter etc.) of the interior wheel 2 of travel mechanism can be above-mentioned corresponding to being in " interior wheel is with being provided with " state makes pair of rolls support 26h move (relatively near or separate).The mutual spacing that thus, can make pair of rolls 26r correspondingly diminishes or becomes big from the diameter (average diameter of the internal diameter of interior wheel end face 2a, external diameter, interior external diameter etc.) of (at interval) and interior wheel 2.In addition, under the situation that pair of rolls support 26h is moved, preferably move keeping under the position relation that is parallel to each other.

Such travel mechanism can realize through the combination of ball-screw (structure that ball rolls between lead screw shaft and nut and rotates) with the AC servo motor.Although do not make special diagram,, for example,, and the AC servo motor is linked respectively with each lead screw shaft as long as pair of rolls support 26h is linked by nut and lead screw shaft respectively, by each AC servo motor each lead screw shaft is rotated control and gets final product.In addition, the configuration attitude of each lead screw shaft is preferably: with respect to the parallel position relation of pair of rolls support 26h, therebetween on the position, be set on the direction with roller support quadrature.As another grasping method, the configuration attitude of each lead screw shaft is preferably set to: an imaginary rotating shaft with respect among the above-mentioned pair of rolls 26r is parallel.Thus, pair of rolls support 26h is moved, the mutual spacing of pair of rolls 26r was correspondingly adjusted with the diameter (average diameter of the internal diameter of interior wheel end face 2a, external diameter, interior external diameter etc.) of interior wheel 2 from (at interval).

And the width of the interior wheel 2 under travel mechanism can be above-mentioned according to being in " interior wheel is with being provided with " state is (for the mutual spacing of interior wheel end face leaves; When adopting another grasping method, for load the height to interior wheel end face 2a from rail wheel with the loading surface 10s of structure (nasal assembly of dashing forward) 10), make pair of rolls support 26h move (in vertical interior foreign steamer dual-purpose microstoning dish) for moving up and down.Thus, can make pair of rolls 26r approaching or leave with respect to interior wheel 2 (interior wheel end face 2a).In addition, under the situation that pair of rolls support 26h is moved, be preferably keeping under the position relation that is parallel to each other and move.

Such travel mechanism can realize through the combination of ball-screw (structure that ball rolls between lead screw shaft and nut and rotates) with the AC servo motor.Although do not make special diagram,, for example,, by the AC servo motor lead screw shaft is rotated control and gets final product as long as the base end part of pair of rolls support 26h is attached on the lead screw shaft that above-below direction extends by nut.Thus, pair of rolls support 26h is moved up and down, make pair of rolls 26r and interior wheel 2 approaching, and in the both sides spots localization of interior wheel end face 2a.

In this case; In above-mentioned travel mechanism; Be used for pair of rolls 26r is set to the processing procedure (process) at the position, both sides of interior wheel end face 2a; Both can be the mutual spacing of adjusting pair of rolls 26r accordingly with the diameter of interior wheel 2 from (at interval) afterwards, the position, both sides of wheel end face 2a in this roller 26r navigated to; Otherwise; Also can be that afterwards, the mutual spacing of adjusting pair of rolls 26r with the diameter of interior wheel 2 accordingly leaves (at interval) to the near zone (the for example inboard near zone at this position, both sides or outside near zone) of in pair of rolls 26r is navigated to, taking turns the position, both sides of end face 2a.

No matter being under the situation of any processing procedure, in step thereafter, all is the pair of rolls 26r through the position, both sides of wheel end face 2a in being arranged on, and wheel end face 2a in this is applied pushing force vertically downward.In order to implement such step, in crimping structure 26, be provided with the pushing force applying mechanism.In addition, as the pushing force applying mechanism, as long as pair of rolls 26r is moved to vertical lower with respect to interior wheel end face 2a.

For example, according to the centre that is arranged on above-mentioned pair of rolls support 26h and with the lead screw shaft of its quadrature be " lever principle " of fulcrum, the base end part of pair of rolls support 26h is moved to vertical direction; And, be the center with this fulcrum, the leading section of pair of rolls support 26h is moved to vertical lower, and pair of rolls 26r is moved to vertical lower with respect to interior wheel end face 2a.Thus, can make interior wheel 2 be crimped onto a plurality of rail wheels loads on each the loading surface 10s (with reference to Fig. 2) with structure (prominent nasal assembly) 10.
