Description

The claimed invention relates to car building, namely to the bodies of passenger cars.

The well-known "Body structure, in particular of a railway passenger car" (Germany, B 61 D 17/04, (10) 0004.01.030.96, (11) 4301763 A1, (22) 01/23/93, (40) 28.07.94, (21 ) 93 4301763, in which extruded profiles (9a ... 9c) have ribs (17) protruding relative to the plates (18) with flanges (20).

The ribs are parallel to one another, and the surface of the flanges are intended for fastening the sheathing sheets (10).

Known side wall of the car body (ed. St. USSR No. 1729865, B 61 D 17/08, claimed 11.22.90), containing a frame formed by uprights and horizontal stiffeners, to which are attached panels consisting of an outer smooth sheet, backed by an inner corrugated sheet. The length of the corrugated sheet of each panel is greater than the distance between the two specified adjacent racks. The corrugations of this sheet are attached to mating racks.

Obviously, we are talking about such sizes of corrugated sheets, the connection of which with each other can be carried out "overlap" or "butt" both in the area of window openings and on the walls of the panels.

In this solution, the entire area of smooth sheets welded into the sheet is covered with a corrugated inner skin to form a panel. The frame is welded separately, and then both are joined together by resistance welding.

The main disadvantage: the frame racks do not directly have a rigid connection with the smooth sheet along the entire height of the side wall, which in some cases leads to the loss of stability of the smooth sheet of the side walls of cars (US patent No. 2314979, NKI 105-401, claimed 09.05.1941; patent WO No. 194173 A1, IPC 7 B 61 D 17/08, filed June 1, 2001, registration number PCT / SE 01/01246), in which the bodywork is identical.

Of these, the closest to the claimed technical solutions is the “Side wall of the body of a passenger carriage” (US patent No. 2314979, NKI 105-401, filed 09/05/1941), containing a sheet of metal sheet (15) with window walls, longitudinally supported along the contour located corrugated sheets (24, 25), end (21, 22) and intermediate, located on the edges of the walls of the profile racks. The latter are connected in a frame by paired, passing along the edges of window openings and single profile runs connected to the sheet by contact welding, corrugated sheets to reinforce the walls and profile strapping.

The manufacture of a famous side wall:

welded on the assembly stand frame;

separately smooth butt weld sheets (web fabrication);

internal corrugated sheets are welded to them with gaps for installing frame elements closed in power rectangles;

the web is pulled by a tensile device (39);

connect the frame and the web by welding.

The main disadvantage of this design is the weakening of longitudinal stiffness, which is why it is complicated by additional details of the frame, namely, the window sill and the lower profile strapping.

The main disadvantages of the assembly method: low-tech connection of smooth and corrugated sheathing and low quality assembly of the canvas with the frame.

The first drawback is due to the fact that the corrugated sheets and the force rectangles of the frame directly during assembly do not connect to each other, but, on the contrary, provide for a perimetric gap between them, as a result, many seams and operations arise.

The second disadvantage is caused by warping of the web as a result of connecting it to the frame in the extended sections of the welding.

The objective of the proposal for objects according to claims 1, 4, 7 is: to simplify the design and assembly technology of the side wall, improve quality, reduce warpage of the fabric during assembly by ensuring uniform distribution of tensile forces and stresses arising from the execution of technological operations of assembly and welding of the fabric, block and side wall as a whole.

For this, the side wall of the carriage contains a sheet of metal sheet with window piers, reinforced along the contour with longitudinally arranged corrugated sheets, end and wall profile racks, the latter are connected to the frame by paired ones running along the edges of the window openings, and single profile runs connected to the sheet by contact welding, corrugated sheets to reinforce piers and profile strapping. New is the fact that the pillar racks are equipped with equal profile corrugations of the L-shape, equal in depth to the corrugations, located between longitudinal corrugated sheets connected to the stiffening belts and welded to the edges of the walls and to the ends of paired runs to form frames, the outer sides of which are connected by welding with single runs and with corrugated sheets reinforcing the sheet walls of the canvas, fixed on the bridges of single runs, and at the top are stiffness relative to the belt and with a gap, the web being reinforced by an angle fitting profile located between the end stand and the ends of the corrugated sheets, the reinforcing shelf of which has a second contact surface formed by a ledge parallel to the web and overlapping with the end rack shelf, and the ends of the corrugated sheets are fixed to the profile shelf, perpendicular to the canvas.

Another feature of the side wall is that the canvas is assembled from smooth strips joined by welding in the longitudinal and transverse directions with parts of the piers, the width of one of which is twice as wide as the other. Window openings on the inner side of the canvas are framed with curly overlays that fit into the frame and the contour of the window opening.

The method of assembling the side wall of the car, which consists in reinforcing the canvas with corrugated sheets and the subsequent connection of the canvas with the frame. What is new is that the fabric before assembly with parts of the frame is pre-reinforced by the number of windows with paired lower and upper girders of the frame and is framed with curly overlays, and the lower and upper corrugated sheets form two stiffening belts when assembling with the fabric, then the fabric is reinforced with end and wall parts of the frame closing: in one plane of contact of the stiffening belt with the end parts of the uprights, and in the other, parallel to it, the ends of paired runs in a frame covering window openings.

As the lining part of the frame, a combined profile is used, the corrugated sheet of which is attached before the assembly of the frame to the external sides of the profile symmetrical arrangement of the L-shaped protrusions of the pylon struts flush with them, and at the bottom to the jumper of a single run connecting them.

A method of assembling a side wall of a car based on welding of smooth strips into a sheet stock, pulling a sheet stock pre-reinforced with corrugated strips along the length and width, and subsequent welding of the carcass elements to the inner surface of the sheet stock. New is that before welding of smooth strips into a sheet blank, they perform laser cutting along the contours of window openings corresponding to them slots, alternating with jumpers that hold the inner parts of the strips, which, after the smooth strips are longitudinally stretched, are welded together with butt welds to form from the mentioned internal parts of technological ties, after which the sheet blank in an inverted position, in a uniformly stretched length and width condition, is supported by two continuous corrugated in strips, then the sheet blank before assembly with parts of the frame is pre-reinforced along the edges of the laser cut contours with paired lower and upper runs of the frame and curly overlays, saturate with end and wall parts of the frame closing the mentioned continuous corrugated strips with end parts of the racks in one plane of contact, and in the other, parallel to it, the ends of paired runs - with profile projections of the racks in the frame, covering the contours of the laser slots, after which the said screed covered by the frame Ki delete.

In addition, a combined profile is used as the lining part of the frame, the corrugated sheet of which is attached before the assembly of the frame to the external sides of the profile of the symmetrical arrangement of the L-shaped protrusions of the pillar racks flush with them, and below - to the jumper connecting a single profile run connecting them.

The technical result is expressed in the following.

The connection in the stiffening belts of the longitudinal corrugated sheets and their closure in the force rectangles by the ends of the racks will eliminate the lower strapping and thereby simplify the design.

The combination of corrugated belts pre-fixed on the canvas and paired girders between each other by the wall end parts of the frame, each stacked: previously interlocked pairs of racks on the corrugated belts, and the profile projections of the racks on the canvas, will simplify the assembly of the frame, its connection with the corrugated sheathing and the canvas.

Welding the ends of the uprights with the stiffening belts by welding will reduce the number of welded spots on the canvas, its outer side will remain smooth. The mass of the end parts of the uprights will decrease by reducing their cross section by the thickness of the corrugated belts.

The location of the corrugated sheet reinforcing wall with corrugations across the wall allows the sheet to be welded to the uprights with intermittent linear seams. At the bottom, the corrugated sheet end faces only to a single run, and at the top it has a gap under the stiffening belt.

The location of the welds in connection with the frame on the inner surfaces of the corrugated strips welded by contact welding to the inner surface of the stretched smooth sheet will eliminate deformation on almost its entire front surface.

The assembly of canvases from pre-stretched strips joined by the parts of the piers in the longitudinal direction, the formation of window openings on a fully assembled side wall will reduce the deformation of the sheets during welding, reduce the complexity of editing them.

Assembling canvases from strips, one of which is twice as wide in width as the other, will make it possible to obtain strips for assembling canvases from standard sheets by dividing them without residue.

The distribution of the frame parts along the bearing sides of the smooth and corrugated sheathing, achieved due to the design of the pillar racks with profile protrusions on their middle parts, equal in height to the corrugations of the inner sheets, and the location of the corrugated sheathing on the two stiffening belts, will allow to connect the frame parts and both sheathing in force rectangles of rigidity along the entire length of the sidewall, and the assembly of parts in the frame is carried out in two contact planes and thereby simplify the assembly.

Performing technological screeds in the canvases contoured by laser slots will evenly transmit forces along and across the contours of the laser slots when tensioning the sheets in the transfer frame, during the final assembly of the blocks in the “assembly-welding conductor”.

Welding of the block parts on a sheet blank uniformly stretched along the length and width, which is transported in a constantly stretched position to further assembly positions by means of a transfer frame, will allow saturation parts to be welded on sheet blanks without deformation of smooth sheets.

Performing technological screeds in the sheet blanks contoured by laser cuts will allow smooth walls to be joined end-to-end when assembling the wall from the finished blocks with transverse (relative to the length of the side wall) tension, and then with longitudinal tension of smooth sheets to establish previously missed pair runs and weld corrugated strips and smooth sheets by means of a corrugated insert and compensating overlays welded to an overlap to it.

Торцы гофрированных листов 6 (7) и поясов жесткости 4, 5 закреплены на полке 30 подгоночного профиля, перпендикулярной полотну. Глубина расположения уступа относительно внутренней поверхности полотна соответствует толщине полки 29.Sheet metal web 2 (Fig. 4) at the ends (Figs. 7, 2, 1) is supported by corner fitting profiles 12, 13, each located on the web between the end stand 12 (13) (Fig. 1) and the ends of the corrugated sheets 6 ( 7) and stiffening belts 4, 5. The corner fitting profile has

-shaped form. The reinforcing shelf 26 (Fig. 7) of the profile has a second contact surface 27 formed by a ledge 28 located parallel to and overlapped with the shelf 29. The ends of the corrugated sheets 6 (7) and the stiffening belts 4, 5 are fixed on the shelf 30 of the fitting profile perpendicular to the canvas .

Canvas 2 is assembled from smooth stripes of equal length joined with welding in the longitudinal and transverse directions with parts of the piers 38, 39, the width of one of the smooth strips is twice as wide as the other.

Butt welds 31 (FIG. 4) of the web 2 and corrugated belts 4, 5 (FIG. 1) are offset relative to each other within the length of the window opening.

The window openings on the inner side of the web 2 are framed by curly overlays 34 that fit into the frame and the contour of the window opening. Curly overlays are connected by spot welding with a cloth to enhance its rigidity in the corners of window openings.

-образным профилем 35 (фиг.1).Racks 12 ... 15 and the canvas 2 are fastened together by a strapping

-shaped profile 35 (FIG. 1).

The method of assembling the side wall of the car (according to claim 4 of the formula) consists in reinforcing the web 2 (figure 4) with corrugated sheets and connecting them to the parts of the frame.

For the manufacture of paintings 40 ... 43 (figure 4) included in the canvas 2, cut the lower 36 and upper 37 (figure 4, 13) smooth stripes of equal length with parts 38, 39 of the walls.

Parts of the piers are joined by welding and get intermediate 42, 43 paintings with window openings 11 (figure 4) and the canvas end 40, 41, which connect the butt welds 31 to each other and get a sheet of metal sheet 2.

Sheet fabric 2 prior to assembly with frame parts is pre-reinforced by the number of windows with paired lower and upper girders 9 and 10 of the frame and is framed with curly overlays 34, and the lower and upper corrugated sheets are reinforced with canvas 2 in two stiffening belts 4 and 5.

As the wall part of the frame, a combined profile is used, the corrugated sheet 8 of which is fastened before the frame is assembled to the outer sides of the profile symmetrical arrangement of the L-shaped protrusions 17, 18 of the wall posts 14, 15 flush with them, and at the bottom to the bridge 21 connecting them single run 16.

Assembly of the wall part of the frame is carried out in a separate welding jig.

-образной формы, но с приваренным к его перемычке 21 (фиг.3) торцом гофрированного листа 8, внутренняя поверхность которого находится в одной контактной плоскости с полкой одиночного прогона 16.A single profile run is fed to the welding jig

-shaped, but with the end face of the corrugated sheet 8 welded to its jumper 21 (Fig. 3), the inner surface of which is in the same contact plane with the shelf of a single run 16.

Corrugated sheet 8 with a single run 16 (figure 1) before welding align in the same contact plane with the profile symmetrical location by the protrusions 17, 18 (figure 6) of the wall profile racks 14, 15 (figure 5).

The linear edges of the corrugated sheet 8 and the ends of the single run 16 are connected by welding to the profile protrusions 17, 18, and a wall part of the frame is obtained having a cross section that allows the walls 3 to be overlapped by this part of the frame and close the pair runs 9, 10 to the power frames.

In the wall part of the frame, the corrugated sheet can be fixed horizontally.

The canvas 2 is saturated with the end and wall parts of the frame, closing in one plane of contact of the stiffening belt 4, 5 with the end parts 23, 24 of the racks 14, 15, and in the other, parallel to it, the ends 9, 10 of paired runs into the frame, covering the window openings.

Single runs, profile protrusions 17, 18 and corrugated sheets 8 are connected to the web 2 by contact welding.

The inner surfaces of the end parts of the struts 23, 24 are connected by welding with the surfaces of the corrugated stiffening belts 4, 5, while the profile protrusions 17, 18 in the other contact plane close the paired runs 9, 10 in the rigid frames framing the window openings welded to the canvas.

Ready door U-shaped blocks 44, 45 are fed to the assembly, then they are connected to the end blocks, and the latter to the intermediate ones.

The resulting gaps at the ends of the corrugated sheathing on the end parts of the web after fixing the U-shaped blocks 44, 45 are compensated by an angular fitting profile, the position of which relative to the end stand 12 (13) can vary depending on the location on the canvas of the ends of the corrugated sheets 6, 7 (Fig. 1) and stiffening belts 4, 5. Fitting profiles are fixed on the inner surface of the web 2, on the ends of corrugated stiffening belts 4, 5, on corrugated 6, 7 end sheets and on the shelves of 29 end racks 12, 13.

Then the frame, the canvas and the door blocks are tied with a profile 35, after which the ends of all the racks are mounted directly on the horizontal frame element of the car, the side surface of which is connected to the overlap 2.

The method of assembling the side wall of the car (according to claim 7) is based on: welding smooth strips with butt welds into a sheet stock, preliminary reinforcing the sheet stock with corrugated strips, pulling the sheet stock along the length and width, welding the frame elements to the inner surface of the sheet stock.

The lower 36 and upper 37 smooth stripes (figure 4) are cut out of sheet metal. Two pairs of strips, lower and upper, both intermediate and end, are used for the manufacture of two intermediate 42, 43 and two end 40, 41 sheet blanks, respectively. Before welding the smooth strips into the sheet blank, they perform laser cutting along the contours of the window openings corresponding to their slots 57 (Fig.13, 4), alternating with jumpers 47 (Fig.13), holding the inner parts of the strips, which after the smooth strips 36 , 37 are longitudinally stretched in the “conductor 50 of the assembly of smooth strips” with the help of tensile devices 51, welded together by butt longitudinal seams 31 '(Fig. 4) with the formation of the mentioned internal parts of the technological ties 59, ensuring uniformity of the longitudinal and transverse tension of the sheet stock in subsequent operations and the distribution of stresses arising during assembly and welding operations.

The sheet blank with the help of the traverse is transferred to the tilter 60, where it is turned face down and in the same position is placed with the same traverse in the "conductor 61 assembly of corrugated strips and paired runs" in the transmission frame 62 pre-fixed on it, equipped with screws 63.

The sheet blank inside the transfer frame is uniformly stretched along the length and width by means of screws 63 and extension strips 64, after which the sheet blank is reinforced with two continuous corrugated strips.

The sheet blank before assembly with parts of the frame is pre-reinforced at the edges of the contours of 57 laser slots with paired lower 9 and upper 10 runs and curly overlays 34.

The frame 62 with the sheet billet stretched inside and the assembled parts is fed to the contact machine 66, where they are reinforced on the sheet billet along its entire length.

The workpiece, supported by continuous corrugated strips, after it is transferred through the frame 62 to the “rack mounting conductor 67”, is saturated with the end and wall parts of the frame closing the said continuous corrugated strips with end parts 23, 24 of the racks in one plane of contact and in the other parallel to it , the ends of paired runs 9, 10 — with profile protrusions 17, 18 of racks 14, 15 into a frame covering the contours of laser cuts 57. Like each of the sheet blanks 40 ... 43 described at positions (61, 66, 67), assemblies saturate with corrugated corrugated strips, paired girders, end and wall parts of the frame, four blocks of two-layer construction are obtained.

As the wall part of the frame in these blocks, a combined profile is used, the corrugated sheet 8 of which is attached before the frame is assembled to the outer sides 19, 20 (Fig. 3) of the symmetrical profile arrangement of the L-shaped protrusions 17, 18 (Fig. 6) of the wall struts 14, 15 (Fig. 1) flush with them, and below - to the jumper 21 (Fig. 3) of a single profile run 16 connecting them.

Blocks of a two-layer construction with frame elements are placed in an “assembly-welding conductor” 69 to form welds between sheet blanks and continuous corrugated strips of adjacent blocks within the length of the closed loop 57 of laser cuts. The adjacent edges of the sheet blanks 40 ... 43 are pulled using transverse tensile devices 56 (Fig. 12) of the conductor 69 (Fig. 9) and connected to the whole web by butt welds 31 (Fig. 4).

The whole web is pulled in the longitudinal direction with the help of tensile devices 51 (Fig. 11) of the assembly-welding conductor 69 (Fig. 9) and reinforced with pair runs 9, 10, which are installed along the lines of closed loops 57 of the laser cuts of four blocks.

The seams between the ends of the sheet blanks 40 ... 43 in the whole web are covered with corrugated inserts 73 (Fig. 8) with corrugated plates 46 pre-welded to them overlap, which are lapped to the ends of continuous corrugated strips and get a wall with two stiffeners 4, 5 (figure 1), after which the wall is expanded with door blocks 44, 45 (figure 1); fixed on the inner surface of the solid web 2 (Fig.4), on the ends of the corrugated stiffening belts 4, 5 (Fig.1), corrugated end sheets 6, 7 and on the shelves 29 (Fig.7) end racks 12, 13 (Fig. 1) - the aforementioned fitting profiles, then the frame, the whole fabric and door blocks are tied with a profile 35 (figure 1).

In the finished side wall, the lintels are cut (for example, with an abrasive cutting tool) and the process ties 59 are removed from the side wall.

Technological ties 59 in this method are obtained by joining two or four internal parts of smooth strips. Couplers of four parts are obtained by sequential joining, first of two parts by longitudinal seams when they are joined by welding into sheet blanks, and then by transverse seams when they are joined into a web.

Couplers with longitudinal intermittent welds made within the contours of laser slots are used to tension along the length and width of sheet blanks when assembling blocks.

Ties with longitudinal and transverse discontinuous seams made within the contours of laser slots are used to tension along the width and length of sheet blanks when assembling the side wall of the car.
