Abstract
The utility model relates to a forming cutter and a processing method for processing a rail top surface of a passenger special rail piece, which have the advantages that the outline processed when a rail piece is processed is round, the top surface can not generate outward deflection after a train passes, and the high train passing smoothness is absolutely and effectively guaranteed. The forming cutter comprises a working edge cap-shaped knife, a non-working-edge cap-shaped knife and a rail top reducing value milling cutter, wherein an R300 circular arc blade is added in the rail top reducing value milling cutter and is positioned on one side of an R80 circular arc blade, and the lap position dimensions of R13 and R80 circular arc blades are adjusted, so that the outline processed by a cutting tool is consistent with a standard steel rail outline. The forming cutter and the processing method for processing the rail top surface of the passenger special rail piece provided by the utility model have the advantages that firstly, by adopting the novel forming cutter for processing the rail top surface of the passenger special rail piece to process steel rails, the steel rail top surface outline is improved, the top surface outline is round and has no a hard edge, and the steel rail and wheel rail relation requirement is met; and secondly, the train passing smoothness and comfortability are effectively improved, the milled contacting euphotic zone mutation is prevented when the train passes, and the train shaking phenomenon brought by single piece processing is eliminated.
Description
Technical field
The utility model relates to that a kind of can to add the profile that processes man-hour at rail spare smoother, cross the car rear top surface and can not produce the inclined to one side outside, and the special rail spare processing tread face profile milling cutter of the visitor that can definitely effectively guarantee the overall height ride comfort and processing method, the objective specially rail spare of genus is processed tread face profile milling cutter and is made the field.
Background technology
The special turnout rail spare process tool of existing visitor only has a cutter, the rail surface R80 circular arc and the 1:40 monoclinic phase that process are cut, the R80 circular arc that requires with theory and R300 circular arc be tangent fine difference, and add processing work limit one side in man-hour at rail spare, the profile that processes exists not smoother, cross the inclined to one side outside of car rear top surface euphotic belt, can't effectively guarantee the high ride (machining profile is seen Fig. 1) of car.
The utility model content
Purpose of design: avoid the weak point in the background technology, design that a kind of can to add the profile that processes man-hour at rail spare smoother, cross the car rear top surface and can not produce the inclined to one side outside, and can definitely effectively guarantee the special rail spare processing tread face profile milling cutter of visitor and the processing method of overall height ride comfort.
Design: in order to realize above-mentioned purpose of design.The utility model is arranged by the optimizing machining technology cutter knife on structural design, makes that the rail top of steel rail facial contour that processes is more smoother to link up, and eliminates tread face euphotic belt jumping phenomenon behind the car, improves ride comfort and the comfortableness of car.
Machining profile design: according to the standard rail profile with produce in the analysis of summarizing of the problem that occurs, improve tread reduction value milling cutter (machining profile is seen Fig. 2), and the tread facial contour divided make two parts and process respectively (machining profile is seen Fig. 3, Fig. 4), guarantee the smoother of profile, eliminate each cutter and connect the corner angle that cutter produces.
Tool Design: the cutter according to the machining profile design is respectively: working edge shape for hat cutter (see figure 5), inoperative limit shape for hat cutter (see figure 6), tread reduction value milling cutter (see figure 7).
Operation principle: according to the standard rail profile, from the identical tool sharpening profile of new design.Add and man-hour tread facial contour integral body is all processed, eliminate the profile defective that the former material of tread face brings.
Technical scheme: the special rail spare processing of a kind of visitor tread face profile milling cutter, comprise working edge shape for hat cutter, inoperative limit shape for hat cutter and tread reduction value milling cutter, increase R300 circular arc blade in the described tread reduction value milling cutter and be positioned at R80 circular arc blade one side, adjust R13, R80 circular arc blade lap position size, make the tool sharpening profile consistent with the standard rail profile.
The utility model is compared with background technology, and the one, use the special rail spare processing of novel visitor tread face profile milling cutter Problems in Machining of Steel Rail, can improve the rail surface profile, the end face profile is smoother without hard rib, more meets the requirement of rail wheel rail relation; The 2nd, can Effective Raise train by ride comfort, comfortableness, prevented train by the time the sudden change that rolls the contact euphotic belt, eliminate the rolling car phenomenon of bringing because of single-piece work.

The specific embodiment
Embodiment 1: with reference to accompanying drawing 2-9.The special rail spare processing of a kind of visitor tread face profile milling cutter, comprise working edge shape for hat cutter, inoperative limit shape for hat cutter and tread reduction value milling cutter, increase R300 circular arc blade in the described tread reduction value milling cutter and be positioned at R80 circular arc blade one side, adjust R13, R80 circular arc blade lap position size, make the tool sharpening profile consistent with the standard rail profile.
1. inoperative limit shape for hat cutter working position.2. working edge shape for hat cutter working position.3. meet the cutter place.4. tread reduction value milling cutter working position.5. meet the cutter place with the working edge inclined-plane.
Embodiment 2: on the basis of embodiment 1, its visitor specially turns the processing method of part processing tread face profile milling cutter, and rail adds man-hour, marks starting point and the inoperative limit shape for hat machining starting point of working edge shape for hat processing at Rail Surface; Use first the former material working edge of working edge shape for hat cutter Problems in Machining of Steel Rail, re-use the former material inoperative of shape for hat cutter Problems in Machining of Steel Rail limit, inoperative limit, add and guarantee that tread face R300, R80 circular arc overlap full man-hour, change tread reduction value milling cutter, begin to process tread reduction value, add that to guarantee to connect cutter man-hour smoother, guarantee the rail 16mm line width 72.2mm of place after the processing.
The tongue work flow:
1) former material clamping.
2) mark starting point and the inoperative limit shape for hat machining starting point that the working edge shape for hat is processed at Rail Surface.
3) check procedure according to drawing.
4) check cutter, workpiece is tried cutter, determine the origin of coordinates of processing.
5) installment work limit shape for hat cutter, beginning processing work limit shape for hat.
6) replacing inoperative limit shape for hat cutter begins to process inoperative limit shape for hat, adds to guarantee that tread face R300, R80 circular arc overlap full man-hour.
7) change the anti-diving tower of tool sharpening tongue and flangeway.
8) change tread reduction value milling cutter, begin to process tread reduction value, add that to guarantee to connect cutter man-hour smoother.
What need to understand is: although above-described embodiment is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
