Description

  The present invention relates to a method of processing a member applied to the outer plate of a vehicle and a member applied thereby.

Normally, the outer plate 103 of the structure 200 shown in FIG. 4 of a railway vehicle is applied from one side with the vertical and horizontal bone members 101 and 102 as an applied member for the purpose of improving its rigidity, and is joined by spot welding or laser welding. it is that has been done that. For this reason, the bone members 101 and 102 have a plate thickness for compensating the rigidity required for the outer plate 103, the joining walls 111 and 121 contacting the outer plate 103, and the rising that rises rearward from these joining walls 111 and 121. Various three-dimensional cross-sectional shapes including at least the walls 112 and 122 are provided. Specifically, there are many hat-shaped cross sections as shown in FIGS. 4 to 7, and there are also Z-shaped cross sections and L-shaped cross sections. Furthermore, at the location where the bone members 101 and 102 intersect, as shown in FIGS. 4 and 5, on the other hand, in many cases, the horizontally oriented bone member 101 is divided so as to avoid the vertically oriented bone member 102. In this case, the joining wall 111 is overlapped on the joining wall 121 of the longitudinal bone member 102 and joined by spot welding or the like at the abutting end portion of the lateral bone member 101 attached to the side portion of the longitudinal bone member 102. In addition, a structure is formed by applying joints to the outer plate 103, and the structural load borne by the joint wall 111 of the transverse bone member 101 is well transmitted to the joint wall 121 of the longitudinal bone member 102. it is not multi-to so that. Such a butting structure between the bone members 101 and 102 is common even when the transverse bone member 101 is butted only on one side of the longitudinal bone member 102 such as along the opening of the outer plate 103. is doing.

However, since the outer plate 103 has low out-of-plane rigidity, the contact surface portion B of the vertical and horizontal bone members 101 and 102 that support the outer plate 103 with the outer plate 103 is required to be smooth. . Therefore, conventionally, in order to satisfy this, as shown in FIG. 4 and FIG. 5, at least a joining wall 111 to be joined to one surface of the outer plate 103 and a rising wall 112 that bends and rises backward from the joining wall 111 are provided. For the bone member 101 that abuts against the side of the other bone member 102, the portion of the joining wall 111 at the abutting end of the bone member 101 that overlaps the joining wall 121 of the other bone member 102 is joined to the other bone member 102. The wall 121 is deformed so as to recede by the thickness t (FIG. 6), and as shown in FIG. 5, a step 116 is formed on the non-processed portion 117 to form a relief portion 104, so-called step processing is performed. (For example, refer to FIG. 7 and FIG. 8 of Patent Document 1) . Thereby, the joining walls 111 and 121 of the vertical and horizontal bone members 101 and 102 are arranged smoothly.

  However, the step processing for forming the relief portion 104 as described above is performed on the fitting member formed by sheet metal as shown in FIGS. 7A and 7B as shown in FIGS. 6A and 7C. Therefore, the initial height H1 shown in FIG. 6b is shortened to H2 shown in FIG. 6c to be H2 = H1-t. However, the initial length L1 shown in FIG. 6b has a degree of freedom. The initial width W1 shown in FIG. 6b due to escape in the width direction of the joining wall is accompanied by a widening of W2 = W1 + 2t shown in FIG. 6c, and is equal to L2 shown in FIG. 6c without being compressed. L1 = L2 It becomes. As shown in FIGS. 4 and 5, the formation of the relief portion 104 forms a stepped portion 116 that crosses the joining wall 111 and extends to the bent portion 113 at the boundary between the joining wall 111 and the rising wall 112. In the bent portion 113, a transition portion 105 (indicated by D in FIGS. 6a and 6b) occurs. This transition portion 105 is subjected to complicated processing in which the step deformation in the out-of-plane direction of the joining wall 111 and the deformation in the in-plane direction of the rising wall 112, that is, compression deformation, are mixed. Due to the springback, the flatness or smoothness of the relief portion 104 of the joining wall 111 after the step processing and the parallelism between the relief portion 104 and the non-working portion 117 are likely to be a bone member 101. Further, the stepped portion 116 of the joining wall 111 cannot change the member width due to abrupt in-plane deformation, and it is easy to make a convex portion that is out of the plane and also faces toward the contact surface with the outer plate 103.

  In such a bone member 101, when the end portion of the joining wall 111 is overlapped with the joining wall 121 of another bone member 102 at the relief portion 104 and joined by spot welding or the like, the spot is applied to the outer plate 103 later. When joined by welding or the like, the distortion of the relief portion 104 of the joining wall 111, the inclination with respect to the non-processed portion 117, the distortion or deformation caused by the convex portion toward the outer plate 103, etc. are given, and the outer plate 103 is finished. The quality may not be good.

However, even if it is an extrusion molding material or a pultrusion molding material, the said characteristic process is implement | achieved by performing the process which forms a hole after shaping | molding and forms an escape part after that.

  Hereinafter, the processing method of the member applied to the outer plate of the vehicle according to the embodiment of the present invention and the member applied thereby will be described with reference to FIGS. 1 to 3 for the understanding of the present invention. . The following description and illustration are specific examples of the present invention, and do not limit the description of the scope of the claims.

  The processing method of the member applied to the outer plate of the vehicle according to the present embodiment is not shown in addition to a hat-shaped cross section whose main body shape is as shown in FIG. 1, but an L-shaped cross section, Z-shaped cross section, C-shaped cross section, Bone or reinforcing material having a cross-section in which a plurality of cross-sectional shapes excluding a U-shaped cross-section, U-shaped cross-section, M-shaped cross-section, arch-shaped cross-section, trapezoidal cross-section, or L-shaped cross-section, and a corrugate in which a large number of these cross-sections are continuous As shown in FIG. 2, a joint wall 11 having a plate-like or corrugated plate-shaped main body and being joined to one surface of the outer plate 3 and a rising wall 12 that is bent backward and rises from the joint wall 11 are provided. 3 or at least the rising edge referred to as a lip or the like that rises rearward lower than the body as indicated by the phantom line in FIG. 3b at the edge of the joining wall 11 of the body of the body. Break that formed wall 12a Or member 1 There are devoted formed with these analogs shaped cross-section, is applied to at least one. Such a fitting member 1 may be formed by sheet metal as shown in FIG. 3 or may be an extrusion molding material or a pultrusion molding material (not shown), and can be used for various applications in various forms.

  The applying member 1 formed by the processing method of the present embodiment has a form as illustrated in FIG. Specifically, as shown in FIG. 2 of the applying member 1, it overlaps with the connecting wall 21 of the other applying member 2 in the connecting wall 11 at the abutting end that is abutted against the side of the other applying member 2. The part is deformed so as to recede by the thickness of the joining wall of the other applying member 2, and the relief part 4 that forms the step part 16 with the non-processed part 11 a, and the boundary between the joining wall 11 and the rising wall 12. The relief part 4 has high flatness or smoothness and high parallelism with the non-processed part 11a. As a result, as shown in FIG. 2, both the side portions or one side of the other applying member 2 are abutted and the relief portion 4 of the connecting wall 11 is overlapped on the connecting wall 21 of the other applying member 2 to perform spot welding or the like. Are joined to each other, the contact surface portions B of the joint walls 11 and 21 to the outer plate 3 form the same plane. Therefore, even if these applying members 1 and 2 are joined by spot welding or the like on one surface of the outer plate 3, as shown in FIG. 2, there is no distortion or protrusion on the outer plate 3. The outer plate 3 can be supported with satisfactory finished quality, and the structure 100 with excellent aesthetics can be formed, which is particularly suitable for a long and large railway vehicle.

  In addition, as shown in FIG. 2, the gusset 17 as a joint member is joined to the back part of the abutting part of the applying member 1 to the applying member 2 by applying spot welding or the like, thereby transferring the load between them. Is also performed. In this case, the gusset 17 can be formed as a flat plate by making the heights of the two orthogonal members 1 and 2 the same as shown in FIG. The joint surfaces of the members 1 and 2 with the gusset 17 are aligned on the same plane, and the degree of adhesion with the gusset 17 is improved. That is, it is possible to prevent the coupling of the gusset 17 from adversely affecting the beauty of the outer plate 3.

  Here, from the viewpoint of structural strength and rigidity, the force that flows through the bone member generally along the rear surface of the outer plate in the vehicle body structure is considered to be axial force, bending moment, shearing force, and torsional moment with respect to the member axis. It is a torsional moment that deforms the cross section of the member itself. However, since the opening area of the hole A is sufficiently smaller than the cross-sectional dimension of the member, the portion where the hole A opens even if the rigidity against the torsional moment at the cross-sectional position where the hole A opens is somewhat reduced. Since the cross-sectional position where the hole A opens at the front and rear cross-sectional positions is supported, the reduction in member strength and rigidity due to the opening of the hole A falls within a negligible range.

  In order to obtain such a fitting member 1, the processing method of the present embodiment has at least a joining wall 11 shown in FIG. 3 b and a rising wall 12 rising rearward from the joining wall 11 in FIG. 2. As shown, for the member 1 that is abutted against the side of the other member 2, the portion of the joining wall 11 at the abutting end is overlapped with the joint wall 21 of the other member 2. In order to adopt a conventional processing method in which the joining member 21 is deformed so as to be retracted by the thickness of the joining wall 21 of the fitting member 2, the bent portion 13 or the figure shown in FIG. 3 b at the boundary between the joining wall 11 and the rising wall 12. The hole A is provided in advance at a position corresponding to the bent portion 13 on the flat plate base material as shown in 3a in the range corresponding to the stepped portion 16 region caused by the deformation, and thereafter, as shown in FIG. non-processed part 11a as shown in c. Processing for deforming so as to form a relief portion 4 having a stepped portion 16 between, specifically performing step processing by pressing.

  In this way, the portion of the joining wall 11 at the abutting end of the fitting member 1 that overlaps the joining wall 21 of the other fitting member 2 is equal to the thickness of the joining wall 21 of the other fitting member 2. Prior to performing the process of deforming so as to retreat, the bent portion 13 at the boundary between the joining wall 11 and the rising wall 12 after the molding of the applying member 1 or the hole A provided at the position corresponding to that before the molding is formed. The joining wall 11 is cut off from the bent portion 13 at the boundary with the rising wall 12 by being in the range of the stepped portion 16 formed between the relief portion 4 formed by the processing of the joining wall 11 and the non-working portion 11a. In the free state, the stepped portion 16 is formed without difficulty by only the out-of-plane deformation of the joining wall 11 alone, and thus has conventionally occurred in the bent portion 13 at the boundary between the joining wall 11 and the rising wall 12. And spring back after processing by the transition portion, it is possible to prevent the can protrusion by escaping from unreasonable plane deformation.

  As a result, with respect to the holding member 1 that is abutted against the side of the other abutting member 2, the relief portion 4 for overlapping the joining wall 11 of the other abutting member 2 on the joining wall 11 at the abutting end. Is formed with a deformation that forms a stepped portion 16 with the non-processed portion 11a, and the hole A provided in the bent portion 13 at the boundary between the joining wall 11 and the rising wall 12 of the fitting member 1 at the time of processing is formed. The step portion 16 of the joining wall 11 is free from the rising wall 12 and the bent portion 13 at the boundary to the step portion 16 and located in the range 5 shown in FIG. The portion 16 is formed without difficulty by only the out-of-plane deformation of the joining wall 11 alone, distortion and inclination due to the spring back after processing, and there is no projection on the side of the contact surface B with the outer plate 3, and high flatness or smoothness And non-machined parts Securing the ascending, 1, can be obtained member 1 There are devoted described above shown in FIG.

  1 to 3 has a hat-shaped cross section, and as shown in FIG. 2, a flange-shaped joint that is abutted against the middle part of another other member 2 and extends outward on both sides. Since the wall 11 overlaps the joining wall 21 of the other fitting member 2, similarly to the case described in Patent Document 1, the processing for forming the relief portions 4 on both the joining walls 11 is performed. However, it is not always necessary to overlap both of the joining walls 11 on both sides, and a plurality of joining walls 11 arranged in a specific position can be selected and overlapped.

  Further, a cross section in which a rising wall 12a called a lip or the like that rises rearward lower than the main body is formed at the edge of the joint wall 11 of the main body of the fitting member 1 as indicated by a virtual line in FIG. In this case, since the rising wall 12a is an auxiliary existence, the bent portion 13 between the joining wall 11 and the rising wall 12a is stepped by partially cutting to a length that does not reach the range in which the stepped portion 16 is formed. The formation of the portion 16 is not affected. However, the rising wall 12a can be formed over the entire length of the applying member 1, and the hole A can be provided in a range corresponding to the stepped portion 16 of the bent portion 13.

  When the holding member 1 is a sheet metal forming material as shown in FIG. 3, the hole A is also formed in the step of taking a flat plate base material as shown in FIG. Can reduce costs. However, even if it is either an extrusion molding material or a pultrusion molding material, the said characteristic process is implement | achieved by performing the process which forms the hole A after shaping | molding and forms the escape part 4 after that.

  The present invention is practically used for forming a relief portion on a joining wall of a fitting member to be joined to one surface of a vehicle outer plate to overlap with a joining wall of another fitting member. This can be achieved without tilting.

It is a perspective view which shows the application member obtained by the processing method of embodiment which concerns on this invention. A relief part formed by making a step between the non-working part on the joining wall of the abutting end of the abutting member by abutting the abutting member on the side part of the other abutting member, It is a perspective view which shows a part of example of a structure joined after overlapping and joining on the one surface of the outer plate | board of a vehicle, after overlapping and joining to the joining wall of a member.
