Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention aims at facilitating automation of production, such as improvement of product quality, by forming a side structure of a stainless steel railcar for each of a plurality of side blocks. The present invention relates to a method for assembling a side structure of a stainless steel railroad vehicle in which it is possible.

[Prior Art] As shown in FIG. 11, the conventional method for assembling a side structure of a stainless steel railroad vehicle is as follows. As shown in FIG. 11, each component member has a length of about 20 m and a width of about 2.3 m. The plate 2, the curtain plate 3, the waist plate 4 and the like were assembled as one body.

[Problems to be Solved by the Invention] However, the conventional assembling method is as described above, and since the length of the side structure 1 is as long as 20 m, it is difficult to carry, forward and reverse, and carry. There is a problem that the accuracy of the product is deteriorated due to the large deformation at the time, and when NC is used, the moving range of the NC device becomes large and it is difficult to maintain the accuracy of the NC device.

[Means for Solving the Problem] The present invention has been made in view of the above-described circumstances, and a side structure extending from a material process to a skeleton assembly process, an outer plate lining process, and a rotary jig process to a phase assembly process. In the assembly process of
In the skeleton assembling step, a plurality of skeleton members made of stainless steel forming a skeleton of the side structure between the entrances and exits to be arranged are made to have a lower surface facing outward of the vehicle. Assembled by reversing so that the outer plate forming the outer part of the vehicle in the next step of forming the outer plate is provided with a window hole between each entrance and exit and is integrally formed with the outer plate member and the waist plate member. And is fixed in an inverted state on a copper surface plate jig that covers the lower surface of the skeleton member to form a side block, and in the next rotating jig step, the side block is placed so that the lower side is inside the vehicle. This invention proposes a method for assembling a side structure of a stainless steel railroad vehicle, which is characterized by rotating forward so that it is on the opposite side, and finally fixing and assembling the curtain plate, the doorway frame, the corrugated plate, etc. in the total assembly process. .

[Operation] The bone bodies that form the skeletons on both sides of the stainless steel railcar are
The skeleton members constituting the part sandwiched between the entrances and exits are divided and assembled, and the skeleton members are provided with window holes formed between the entrances and exits and integrally formed with the blower. A plate-shaped outer plate member and a waist plate integrally formed between the entrance and the exit are fixed to each other to form a plurality of side blocks, and the entrance and exit frame and the curtain plate are integrated into one of these side blocks. By being assembled, transportation and forward / reverse are easy, and since the deformation during transportation is small, it is possible to improve the accuracy of the product and also the accuracy when converting to NC. This is a method of assembling the side structure of a stainless steel railcar that can be used.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a flow chart showing the assembling method of the present invention. In the drawing, 10 shows the steps of the material process. Using these materials, as shown in 11 of the bone body assembling process, stainless steel is first prepared. Side structure 15 (eighth shape) of the railcar, which has a substantially symmetrical shape.
The bone body 16 of the right half from the center is omitted) is assembled. As shown in FIG. 2 with the right half omitted from the center, the assembly of the skeleton 16 constitutes the skeleton 16 of the side structure 15 between each entrance 17 and the entrances 17 arranged at appropriate intervals. Are formed separately for each of the skeleton members 18a, 18b, ... made of a plurality of stainless steels. At this time, as shown in FIGS. On the surface plate jig 20 formed on a certain height, the lower surfaces of these skeleton members 18a, 18b, ... are made to face outward of the vehicle (referred to as “inversion”). ), Resistance welding, arc welding, or the like.

Next, as shown in FIG. 1, the skeleton members 18a, 18b, ...
Is transferred to the step 12 of covering the outer plate. As shown in FIG. 3, the step 12 of forming the outer plate is performed such that the outer plate 21 forming the outer portion of the vehicle is divided between the entrances 17 and the entrances 17 and the entrances 17 of the entrances 17 are separated. A window hole 22 between
Further, the outer plate members 24a, 24b ... In which the blower 23 between them is also integrally formed, and the waist plate members 25a, 25b (fourth) which are divided for each of the entrances 17 (Shown)
As shown in FIGS. 10 (a) and (b), the skeleton members 18a, 18b, which are positioned at a certain height, are placed on a base 27 having legs 26.
The outer plate members 24a, 24b ...
The bone members 18a, 18b, ... Are placed and positioned on the waist plates 25a, 25b ... And then fixed to the copper surface plate jig 28 by a vise or the like. Then, these bone members 18a, 18a and
.., outer plate members 24a, 24b ... and waist plate members 25a, 25b ... are fixedly formed to form side blocks 29a, 29b.

Next, as shown in the rotating jig process of FIG. 1, the side blocks 29a, 29b ... Are respectively rotated by the rotating jig so that the lower side faces the inside of the vehicle (in this state. Is referred to as "forward rotation"), and in the process of total assembly shown in FIG. 14 at 14, the side blocks 29a, 29b ..., At the curtain plate shown at 30 in FIG. 5 and at 31 in FIG. The entrance / exit frame shown in FIG. 7 and the corrugated plate shown in FIG. 32 and the reinforcing strips shown in 33 in FIG. 7 are fixedly assembled by resistance welding or arc welding, and the side of the stainless steel railcar shown in FIG. A structure 15 is formed. It should be noted that the side blocks 29a, 29b ... Are formed for each of the portions divided by the one-dot chain line 34 in FIG.

[Advantages of the Invention] Since the method of assembling the side structure of the stainless steel railcar according to the present invention is as described above, it has the following effects.

(1) Since the skeleton, the outer plate, and the waist plate are assembled in a state in which they are divided for each side block as described above, when they are conveyed to each step and when they are inverted in the inversion step,
It can be made easier and the deformation is small,
Product accuracy can be improved.

(2) Since it is formed for each side block as described above, it is possible to assemble on a plate-shaped platen jig in the inverted state, so that it is possible to maintain the planar level of the plate-shaped outer plate more. It's easy.

(3) Since it is formed for each side block, the moving range of the NC device becomes smaller even when it is automated, and the manufacturing accuracy by the NC device can be improved.

(4) By forming each side block as described above, the jig can be made smaller, the jig manufacturing cost can be reduced, the jig accuracy can be improved, and the manufacturing process can be made takt. Is.
