Definitions
- the invention relates to a method for grinding at least the traveling mirror of a rail, in particular a railroad track, by generating a relative movement between a grinding wheel having a counter profile to the profile of the traveling mirror and a rail in its longitudinal direction, and a device for carrying out the method.
- cup wheels to grind the convex transverse profile of a rail, such as a railroad track, which has the driving mirror.
- a rail such as a railroad track
- This large number of crossings causes inaccuracies, since the track produced with each crossing cannot be aligned exactly with the previously ground track.
- the invention aims at avoiding these disadvantages and difficulties and has as its object to create a grinding method of the type described in the opening paragraph which, on the one hand, enables sufficient material removal for rails in one pass for the entire cross-section to be ground, and on the other hand prevents overheating of the rail material. Furthermore, the grinding wheel should have a sufficient service life, e.g. in spite of high performance, ie despite the large length of rail ground per unit of time.
- This object is achieved in that the axis of the grinding wheel includes an angle ⁇ deviating from 0 ° with a plane perpendicular to the longitudinal direction of the rail.
- a device for performing the method has the following features:
- a device for generating a relative movement between the rail and the grinding wheel
- Preferred embodiments of the device are contained in subclaims 25 to 36.
- FIG. 1 illustrating a side view of an apparatus for carrying out the method according to the invention
- FIG. 2 illustrating a schematic plan view in the direction of arrow II in FIG. 1.
- Fig. 3 shows a variant of the device for performing the method according to the invention.
- Fig. 4 shows the cross section through a railroad track in different states of the rail.
- Fig. 5 shows the engagement of the grinding wheel according to the inventive method on a railroad track, which is illustrated in cross section.
- the rail head 3 seated on the rail web 2 has a convex cross-sectional part 5, which has the driving mirror 4, on which the running wheel of a rail vehicle runs, which is illustrated by line A in the new state.
- this convex part 5 of the cross section of the rail head 3 is given the shape illustrated by the line B.
- the rail 1 is reworked so that the convex part 5 of the rail head 3, but at least the traveling mirror 4, in turn illustrates the original state, that is to say the original cross-sectional shape the line C - reached as close as possible.
- the rail head profile should be reprofiled, for which purpose the milling and grinding according to the invention is intended.
- new rails it is advisable to remove the rolled skin in order to achieve better running properties, a longer service life and noise reduction; the grinding process according to the invention without prior milling is sufficient for this.
- FIG. 1 and 2 show a device according to the invention, which is arranged in a stationary manner and on which the rail 1 to be machined is moved past.
- Fig. 3 shows a device according to the invention, which is installed in a mobile device, such as a locomotive, so that rails that have already been laid can be processed with this device.
- the device according to the invention is duplicated, so that both the left and the right rail can be finished with one pass.
- the mutually identical parts and devices of the stationary device and the mobile device are provided with the same reference numerals.
- the milling cutter 8 is designed as a circumferential milling cutter.
- This milling cutter 8 can be driven via a drive motor 9 and a gear 10, the direction of rotation being selected such that the rail 1 is machined in a synchronous milling process.
- a grinding unit 11 is provided directly adjacent to the milling unit 7, the grinding wheel 12 of which can be driven by means of a drive 13, etc. preferably also in the direction of rotation as the milling cutter 8, so that a synchronous grinding on the rail 1 is carried out.
- the grinding wheel 12 is equipped with a grinding depth control 14, so that the grinding wheel 12 can be continuously adjusted according to its wear on the rail 1.
- This grinding depth control 14 comprises a measuring device for measuring the continuously decreasing diameter of the circumference of the grinding wheel 12; it can also access measurement data from measurements of the drive torque. Both the milling chips and the grinding chips or grinding dust are vacuumed off immediately after they have been created, etc. via suction devices 15 and 16.
- guides 17 are provided for the rail 1, against which the rail 1 can be pressed by means of support rollers 18, wherein at least the driving mirror 4 of the rail 1, preferably the apex of the rail head 3, can be pressed , Furthermore, lateral guide rollers 19 engaging on both sides of the rail head 3 are provided along the device, the lateral guide rollers 19 resting on the side of the running edge 6 of the rail 1 being fixed in their position. The rail is pressed by the side guide rollers 19 resting on the opposite side against the fixed side guide rollers 19, whereby the rail 1 assumes an exact position with respect to the milling unit and grinding unit.
- a further guide 20 is provided, which is provided with a damping device in order to eliminate vibrations on the rail 1 caused by the milling cutter.
- the axis 21 of the grinding wheel is inclined relative to a plane 22 which is perpendicular to the longitudinal direction of the rail by an angle ⁇ which is greater than 0, preferably between 1 and 20 °, etc. in each case depending on the state of the rail 1 before grinding.
- the angle ⁇ is expedient between 5 and 12 °, ideally at 8 °.
- a smaller angle ⁇ is expedient to ensure an optimal machining volume with a long service life of the grinding wheel.
- the grinding wheel 12 is already pre-profiled when new, ie it has approximately the counter profile to the rail 1.
- a puller 23 with a sharpening stone 24 is advantageously provided, which can be pressed against the circumference of the grinding wheel 12.
- This whetstone has exactly the desired profile to be produced and it also includes the angle ⁇ with the grinding wheel.
- This sharpening stone 24 is pressed against the grinding wheel 12 before the first rail 1 begins to be sanded until it has taken on its profile.
- the honing stone 24 can be lifted off the grinding wheel 12, because the grinding wheel profiles itself on the preliminary profile, ie on the milled rail head surface or on the rail head surface still provided with the rolled skin.
- the sharpening stone can optionally be placed on the grinding wheel 12 for temporary sharpening while a rail head 3 is being machined on the grinding wheel 12.
- the rail 1 can also be used, provided it is milled with sufficient accuracy or still has the rolled skin.
- the profiled grinding wheel 12 primarily has the task of smoothing the shafts generated by the milling cutter 8 and generating a longitudinal grinding pattern.
- the inclination of the grinding wheel 12 according to the invention results in particularly good engagement conditions and a high smoothing effect.
- the engagement of the inclined grinding wheel 12 is illustrated in FIG. 5. It can be seen that the inclined position gives a favorable pressure angle, in particular at the transition of the convex part 5 of the rail head 3 into the side surfaces 25 of the rail head 3. These favorable conditions of intervention also permit a sufficiently large amount of material to be removed with very good thermal behavior at these points, so that no fire can occur on the ground surface. This also results in a very good service life for the grinding wheel 12.
- the axis 21 of the grinding wheel 12 is also inclined with respect to the longitudinal symmetry center plane 26 of the rail, etc. by an angle ⁇ , the size of which can be between 1 and 20 °.
- the axis 21 of the grinding wheel 12 can expediently be arranged to be adjustable on the device.
- the milling unit 7 and the grinding unit 11 are installed in a rail milling train 27.
- the milling cutter 8 and the grinding wheel 12 are moved approximately vertically against the rail 1 by means of adjusting devices 28 until the guides 17 and 20 rest on the rail head 3.
- a movement of the Grinding unit 11 and the milling unit 7 in the lateral direction to the driving edge 6 are also possible until side guide rollers 19 rest on the rail head 3.
