Definitions

  • the present invention refers to a method for assembling railway cars or similar.
  • the invention refers to a method for assembling a railway car realised by welding aluminium alloy extruded panels.
  • the assembling of railway cars having an aluminium alloy car body is traditionally performed preparing separately the floor or ground of the car, the two body sides and the roof, and then welding together these four parts lengthwise.
  • floor, body sides and floor are generally obtained each by the junction of a plurality of aluminium alloy extruded panels that are joined together and welded lengthwise on both sides.
  • the present extrusion techniques in fact do not allow to obtain aluminium alloy panels having suitable dimensions for realising a whole body side or a roof or a floor of a railway car.
  • FIG 1 An example of a car body of a railway car assembled according to well-known techniques is shown in figure 1.
  • figure 1 in cross section, are visible a floor 1, two body sides 2, 3 and a roof 4, joined together by internal welds 6, 7, 8, 9 and external welds 6', 7', 8', 9'.
  • the floor is made up by the junction of aluminium alloy extruded panels 1a-1g, previously welded together lengthwise, and rests on two lateral supports 5, 5'.
  • the lateral sides 2 and 3 are made up by the junction of panels 2a-2d and 3a-3d, while the roof 4 comprises five panels 4a-4e.
  • the traditional car body assembling method provides initially for welding internally and externally the two body sides 2 and 3 to the floor 1.
  • the internal welds 6 and 7 are made by skilled workmen working inside the car body, while the external welds 6' and 7' are preferably made in an automated way working on the external side of the body by means of welding arms.
  • the roof 4 is positioned, welding it to the body sides 2 and 3, first manually from the inside, carrying out the internal welds 8, 9 and then from the outside by means of robotized arms carrying out the external welds 8', 9'.
  • a manual intermittent weld generates often a final product that is not perfectly aligned.
  • a weld obtained by an automated system guarantees a better and constant quality, reduced working times, and total security for workmen.
  • a first object of the present invention is therefore to provide an assembling method for an aluminium alloy car body for a railway car that allows to perform in an automated way all the longitudinal welds, overcoming the drawbacks of the prior art.
  • Another object of the present invention is to provide an element of a car body for a railway car, obtained by the junction of several extruded aluminium alloy panels, by means of automated welds carried out by a single side, without therefore the necessity of moving or turn over the element during working.
  • an element of a car body for a railway car formed by the junction by welding of at least two extruded aluminium alloy panels 40, 42 each having an internal wall 40', 42', an external wall 40'', 42'' and two connecting sides 46, 48.
  • the connecting sides 46, 48 of two adjacent panels 40 and 42 are so shaped that, when they are joined for welding, the internal wall 40' of a panel is in contact with the corresponding internal wall 42' of the adjacent panel, while the opposed external walls 40'' and 42'' remain spaced forming a longitudinal opening accessible from the outside. That opening allows to perform, working from the outside and therefore possibly by means of automated systems, a continuous weld 39 along the contact line between the internal walls 40', 42'.
  • the longitudinal opening has preferably a "V" shaped transversal section, facilitating the automated welding operations.
  • the longitudinal opening is closed applying an aluminium alloy junction element 44, preferably having the same length of the panels, suitable for joining the spaced external walls 40'', 42''.
  • Said element 44 is therefore welded, working again on the external side, along contact lines 31, 33 defined between the junction element 44 and the adjacent walls of panels 40 and 42.
  • the junction element 44 has a triangular cross section so that it can be inserted perfectly into the opening.
  • engaging means 27, 28 suitable for containing a terminal engaging portion 30 present in the junction element 44, as better visible in figure 3.
  • Said engaging means 27, 28 form a longitudinal groove, over the weld 39, having a shape complementary to the shape of the terminal engaging portion 30.
  • junction element 44 when inserted into the longitudinal opening, rests on two lowered zones 34 and 36 obtained on the extremities of the external walls 42'' and 40'' of the panels, so that its external surface is at the same level then the adjacent surfaces.
  • a port 32 is provided between the terminal engaging portion 30 and the junction element 44 so that, during welding, the element 44 can be pressed against panels 40 and 42 in order to overcome eventual geometrical defects of the parts.
  • junction element 44 As the junction element 44 is positioned, starts, by means of an automated welding arm sliding along all the panels length, its welding firstly with panel 41, weld 31 in figure 3, and then with panel 42, weld 33.
  • This connecting system allows therefore to join together lengthwise two aluminium alloy extruded panels working on a single side and in a completely automated way.
  • the floor is made up by the junction of a plurality of panels 10a-10g and rests on two lateral supports 15, 15'.
  • the lateral sides 12 and 13 are made up by the junction of panels 12a-12d and 13a-13d, while the roof comprises five panels 14a-14e.
  • the method according to the invention provides the steps of:
  • all said welds can be realised by means of automated welding arms, sliding along all the railway car length and coupled to the structure or "cathedral" that surrounds the railway car under construction.
  • the proposed method allows to assembly an aluminium alloy car body of a railway car in a fully automated way, without the need of carrying out manual welds inside the car body.
