Description of the Related Art In a side structure of a railway vehicle, there is a structure in which a skeleton such as a pillar, a lateral bone and the like and an outer plate support the self-weight of the vehicle body and a passenger load. There is a reinforcement bone on the inside surface of the outer panel,
Since a plurality of reinforcing bones are attached to the lumbar region, the number of parts increases. For example, as shown in Japanese Patent Application Laid-Open No. 61-220963, a reinforcing panel formed by press-forming a plurality of beads on the inner side surface of an outer plate is attached. A technique for reducing the number of parts while maintaining the same effect is disclosed. Further, as shown in Utility Model Registration No. 2592092, a reinforcing panel formed by press-forming a bead corresponding to a pillar or a transverse bone is attached to a vehicle inner side surface of an outer plate instead of a frame such as a pillar or a transverse bone. Some construct side structures.

きないケースが多い。However, these reinforcing panels are formed by integrally pressing a plurality of beads. However, in the case of the integrated pressing, the size of the reinforcing panel differs depending on the mounting portion of the outer plate. In addition, a press die is required for each reinforcing panel. Also, a large press die is required,
In order to be able to produce products with the desired finish without cracks, wrinkles, etc., it is necessary to repeatedly reproduce and correct the press mold,
Although mass production will be cheaper if it gets on track, initial costs such as mold costs and prototype costs until mass production are high,
Since it takes time to prototype, the delivery time is lengthened. On the other hand, many railcars are made to order based on the circumstances of each railway company.Therefore, considering the customer service facilities desired by each railway company, consider the layout inside the train, and arrange the windows of the structure and the arrangement of the side pillars accordingly. Is a general design process. Under such circumstances, it is rare that the production amount which can amortize the mold cost and the trial production cost by the integrated press is collected. Furthermore, the length of the vehicle body is limited by the vehicle limit, and considering the layout so that the doors are arranged at equal intervals in that range, it is necessary to change the width of the reinforcing panel naturally at the waist under the window and at the waist of the door pocket. is there. In addition, since the size and shape of the reinforcing panel are different between the waist portion and the blow-by portion, reinforcing panels of various sizes and shapes are required for each vehicle type. Therefore, in many cases, the production amount cannot be reduced and the cost cannot be reduced with the reinforcing panel formed by the integrated press.

A skeleton is composed of the side pillars composed of the window pillars 3, the lateral bones composed of the curtain band 4, the waistband 5, and the long base 6, and the lumbar pillars 7 below the window opening, and the outer plate 8 is welded to the framework. A reinforcing panel is attached to the inner side surface of the outer panel 8. The reinforcing panel is attached to a blower reinforcing panel 9 attached to the outer panel 8 of the blower, a waist reinforcing panel 10 attached to the waist outer panel 8 below the blower, and attached to the outer panel 8 below the window opening. There is a reinforcement panel 11 under the window.

The waist reinforcement panel 10 has a long bead 12 formed in the vehicle front-rear direction, and the under-window reinforcement panel 11 has a short bead 13 formed in the vehicle front-rear direction.

2 is a press die 14 and a terminal press die 15 shown in FIG.
And molded. In this molding method, first, a part of the terminal press die 15 is pressed on the end of the bead pressed by the press die 14, while pressing the press die 14, exchanging the material for the terminal press die 15, and feeding the material. This is repeated to form a bead 12 having a desired length. In addition, the forming direction of the beads 12 and 13 in each reinforcing panel is not limited to the above-described direction, and may be a direction corresponding to the flow of stress in the mounting portion of each reinforcing panel.

の短縮の面で非常に有効である。As described above, forming the beads 12 and 13 one by one is less productive than the integrated press forming, but uses the same press dies 14 and 15 even if the size or shape of the reinforcing panel changes. Since the bead having a desired length can be formed, and the number and arrangement of the beads can be freely set, the bead can be manufactured without worrying about the mold cost even in small-scale production. In addition, it is difficult to predict the flow of material in the press die, and wrinkles and cracks are generated. Therefore, it is necessary to correct the press die by trial and error until a satisfactory product is obtained. There is no need for such a small area. Further, a press die can be used semi-permanently. Therefore, it is very effective in reducing cost and delivery time.

である。As described above, according to the method for manufacturing a railcar outer panel reinforcing panel of the present invention, a plurality of beads are press-formed one by one on a reinforcing panel attached to the inner side surface of the outer panel. Even if the size or shape of the panel changes, beads of the desired length can be formed using the same press mold,
Since the number and arrangement of the beads can be freely set, even a small-scale production can be performed without worrying about the mold cost.
Also, since the pressing range is small, there is no need to modify the press die, and the press die can be used semi-permanently, which is very effective in terms of cost reduction and delivery time reduction.
