6 Claims. (CI. 90-24) The invention relates to apparatus for removing weld burrs from butt-welded material in bar form and of constant cross-section and will be described further, by way of example, with reference to the accompanying drawings which illustrate a preferred embodiment of the apparatus.
In the drawings:
FIG. 1 is a view in end elevation of the apparatus corresponding to the arrows I in FIGS. 2 and 4;
FIG. 2 is a view in section on line II-II of FIG. 1;
FIG. 3 is a View in section on line lIL-III of FIG. 2; and
FIG. 4 is a view in section on line IV-IV of FIG. 2.
The apparatus shown comprises a bearing framework having a base-plate 11, two side walls 12, a cover plate 13 and a rear end wall 14. Secured to the baseplate 11 is a slideway 111 forming a guide for the underside of the base of a piece of rail. The rear end wall 14 is formed with an aperture 141 adapted to the cross-section of the space bounded by the baseplate 11, side walls 12 and cover plate 13. This cross-section is large enough to receive the sectional shape of the rail A. The rear end wall 14 and the elements secured thereto are not shown in FIG. 3, and the rail A has been omitted in FIG. 2. Two guide rollers 21 are rotatably mounted in the cover plate 13 and project therebelow. Two sliding members 22 are adjustably mounted in each side wall 12. The elements 21, 22 form guides for guiding the apparatus on the burrfree part of the rail A. Four deburring knives are disposed at the front end of the box 1 and comprise a knife 3 for the top of the rail, two lateral knives 4 for the rail web and the underside of the top of the rail and the top and side surfaces of the rail foot, and a knife for the underside of the rail foot. The knives 3, 4 are each mounted for movement on the frame between an operative position and a withdrawn inoperative position and are each connected to means for moving them forwardly and backwardly between such positions. The knives 3, 4 are shown in this operative positions in FIG. 1. The knife 5 1S stationary, being adjustably secured to the baseplat e 11 by screwed fasteners 51 in manner such that its cutting edge 5a is coplanar with the upper surface of the slideway 111.
The knife 3 is adjustably mounted on a support member 31 by fixing screws 311 passing through slots in the knife 3 and by adjusting screws 312. The support member 31 ismounted for movement in guide ledges 32 and has a toothed rack 33 engaged by a quadrant rack 34. The latter is adapted to be displaced by a crank 35 to which a piston rod 36a, 36b of a reciprocating unit or ram 37 is connected, the cylinder of the unit 37 being connected by a joint 38 to the rear end wall 14. The unit 37 has cylinder covers 371, 372. The piston rod comprises the two rod elements 36a, 36b so interconnected by a coupling member 361 that the length of the complete piston rod can be adjusted.
A shoe 30 is secured to the support member 31. By means of the adjusting screws 312, the knife 3 is so adjusted that its cutting edge 3a and the underneath rubbing surface of the shoe 30 touch the rail A simultaneously when the drive system, composed of elements 33, 34, 35,
36a, 36b and 37, moves the support member 31 towards the rail A.
The side knives 4 are each correspondingly mounted, by means of fixing screwed fasteners 411 passing through slots in the knives 4 and adjusting screws 412, each on a respective support member 41, the members 41 being movable in guides 42 and each having a toothed rack 43 engaged by a quadrant rack 44. Each rack 44 is driven by a crank 45 to which piston rod 46a, 46b of a reciprocating unit or ram 47 is connected. Like the piston rod 36a, 36b, the piston rod elements 46a, 46b are interconnected by a coupling element 461 so that the length of the complete piston rod can be varied. The cylinders have covers 471, 472.
Abutments 41' so limit the movement of the support members 41 from the normal position into the operative position of the knives 4 that the cutting edges of the latter either touch the web of the rail A when in the operative position or are at a reduced distance from such web.
When the knives 3, 4 are advanced from the normal positions to the operative positions or are returned therefrom to the normal positions, the cranks 35, 45 perform less than half a revolution, such movement being out side the dead center positions. The pistons of the units 37, 47 are double acting pistons which are loaded on one side to advance the knives and on the other side to withdraw the same. The lengths of the piston rods 36a, 36b and 46a, 462; can be varied to adjust the force retaining the knives 3, 4 in the operative position. The units 37, 47 can be of hydraulic or pneumatic type, and purely mechanical advancing and return devices can be used instead of the devices 3335, 36a, 36b, 37 and 43-45, 46a, 46b, 47 hereinbefore described.
The following description illustrates a method of operating the apparatus hereinbefore described in relation to a butt-welding machine for railway rails.
The apparatus is disposed, with the knives 3, 4 in the inoperative position, in the usual upsetting slide or carriage of the welding machine (of which only part is shown, as will later be apparent) so that the knives 3, 4 and 5 are near the machine'welding station and one of two rails A which are to be welded together, having been introduced into the machine, extends through the apparatus. When such rail A is introduced into the machine, the guide rollers 21 roll on the rail. After welding, the one or more clamping device of the upsetting carriage is/ are released, and the apparatus is moved between the clamping jaws of that clamping device which is nearest the welding station, the apparatus running along the rail with the interposition of the rollers 21. The apparatus is clamped in this clamping device, whose jaws are shown only in FIGS. 1 and 3 and are therein indicated by the reference numeral 6. The pistons of the units 37, 47 are operated to bring the knives 3, 4 into their respective operative positions, whereafter the upsetting carriage is moved to advance the apparatus over the weld zone of the rails so that the knives 3, 4, 5 remove the burr, the knives being retained in the operative position by the pressure acting on the pistons of the units 37, 47. The shoe 3% slides along the top of the rail head, so that the cutting edge of the knife 3 is kept exactly at the height of the top of the rail head during deburring and produces a satisfactory running surface at the deburr weld zone between the rails. After deburring, the knives 3, 5 are returned to their normal positions and the one or more clamping device or jaw of the stationary part of the machine is/ are released, whereafter the welded rails, which have been dehurred at the weld zones, can be removed from the machine, the rollers 21 running first on one and then on the other rail.
The apparatus, according to the invention, instead of being disposed in the upsetting carriage, can be disposed in the stationary part of the welding machine and can be clamped in such part after welding, whereafter the upsetting carriage is driven so to move the two rails that the weld zone of the welded-together rails passes between the deburring knives.
