  Next, a method for manufacturing the skirt guard bracket 17 will be described. FIG. 7 is an explanatory diagram showing a method of cutting out more intermediate bodies 170 of the skirt guard bracket 17 from one plate member 100. As the plate member 100, for example, a regular steel plate of 1219 mm × 2438 mm or 1524 mm × 3048 mm is used. A flat plate-like intermediate body 170 is cut out from the plate material 100 by a laser processing machine.

  FIG. 8 is an enlarged plan view showing the intermediate body 170 of FIG. The skirt guard bracket 17 is produced by bending the intermediate body 170 in FIG. In other words, the intermediate body 170 is a part in which the entire skirt guard bracket 17 is developed in a planar shape.

  The outer shape of the skirt guard bracket 17 is a shape that is symmetrical with respect to the center line C of the bracket base portion 17a when the entire skirt guard bracket 17 is flattened.

  The outer shape of the skirt guard bracket 17 is such that when the entire skirt guard bracket 17 is flattened, a recess 170b is provided between the upper abutting portion 17d and the lower abutting portion 17e, and the bracket base portion 17a The convex portion 170a is provided on the opposite side of the concave portion 170b between the bracket upper surface portion 17b and the bracket lower surface portion 17c.

  When the intermediate body 170 is cut out from the plate member 100, as shown in FIG. 7, the cut line of the concave portion 170b and the cut line of the convex portion 170a of the adjacent intermediate body 170 are common. That is, the convex portion 170a and the concave portion 170b of the adjacent intermediate 170 are processed simultaneously. For this reason, the width dimension β of the convex portion 170a is equal to or smaller than the width dimension α of the concave portion 170b.

Hereinafter, a specific procedure of the manufacturing method of the skirt guard bracket 17 will be described.
<First step>
First, the plate material 100 is installed on a processing table of a laser processing machine (not shown). Next, as shown in FIG. 9, an identification symbol 101 such as a part number is marked for each intermediate body 170. Assuming that the lower end portion of the plate member 100 of FIG. 7 is the first end portion and the upper end portion is the second end portion, in FIG. They are attached in order toward the second end.

  When marking of the first row is completed, marking of the second row is performed in order from the second end side. Then, identification symbols are marked at positions corresponding to all the intermediates 170 in FIG.

<Second step>
Next, as shown in FIG. 10, a part of the outline 170 of the intermediate body 170 and all holes are processed. In FIG. 10, outline processing and hole processing are performed for each intermediate body 170 in the direction of the arrow. It is efficient to start the second step from the end on the side where the first step is completed, of the first end and the second end of the plate member 100.

  FIG. 11 is an explanatory diagram showing processing performed on a portion corresponding to one intermediate body 170 in the second step. The outline processing starts from the processing start point 102. The outline processed in the second step is a common outline of adjacent intermediate bodies 170. For this reason, the laser irradiation position of the laser processing machine is set so that the center of the laser diameter matches the center line of the processing line.

  In the second step, drilling is started after outline processing. The hole machining is sequentially performed from the end side near the processing end point of the outline machining to the end side near the machining start point 102 of the outline machining out of both ends in the width direction of the intermediate body 170. In FIG. 11, the holes 103, 104, 105, 106, 107, 108 and 109 are processed in this order.

  When the processing of the hole 109 is completed, the laser irradiation position is moved to the processing start point 102 for the next contour processing of the intermediate body 170.

  When the outline processing and the hole processing in the first row are completed, the outline processing and the hole processing in the second row are sequentially performed from the first end portion to the second end portion. Then, outline processing and hole processing corresponding to all the intermediate bodies 170 in FIG. 7 are performed.

  The last intermediate body 170 located at the first end of the plate member 100 may be subjected to hole processing in the reverse order as described above, and the hole processing may be terminated at the hole 103 in preparation for the next step. .

<Third step>
Next, as shown in FIG. 12, further outline processing is performed. In FIG. 12, outline processing is sequentially performed for each intermediate body 170 from the first end portion to the second end portion of the plate member 100. It is efficient to start the third step from the end of the first end portion and the second end portion of the plate member 100 on the side where the second step is completed.

  In the third step, first, outline processing is performed from the processing start point 111a to the processing end point 111b. Next, the laser irradiation position is moved to the machining start point 112a, and outline processing is performed from the machining start point 112a to the machining end point 112b.

  A first joint portion of about 0.5 mm is secured between the processing end point 111b and the processing start point 112a. Thereby, it is suppressed that the intermediate body 170 falls between the sword mountain-shaped support parts of a processing stand.

  Subsequently, outline processing is performed from the processing start point 113a to the processing end point 113b. Thereafter, outline processing is performed from the processing start point 114a to the processing end point 114b. Next, the laser irradiation position is moved to the machining start point 115a, and outline processing corresponding to the right side portion of the intermediate body 170 in FIG.

<4th process>
After the outer shape processing in the third step is performed on the intermediate body 170 located at the second end of the plate member 100, the laser irradiation position is moved to the processing start point 116a in FIG. In the fourth step, the remaining outline processing is sequentially performed for each intermediate body 170 from the second end portion of the plate member 100 toward the first end portion.

  In other words, in the fourth step, outline processing is performed from the processing start point 116a to the processing end point 116b. Next, the laser irradiation position is moved to the machining start point 117a, and outline processing is performed from the machining start point 117a to the machining end point 117b.

  A second joint portion of about 0.5 mm is secured between the processing end point 116b and the processing start point 117a.

  Subsequently, outline processing is performed from the processing start point 118a to the processing end point 118b. Hereinafter, the outline processing corresponding to the left side portion of the intermediate body 170 in FIG.

  When the third step and the fourth step for the first row are completed, the third step and the fourth step are performed for the second row and thereafter.

<Fifth step>
When the third and fourth steps are completed for the entire plate material 100, the plate material 100 is taken out from the laser processing machine. Then, the intermediate body 170 is separated from the plate material 100 by a press machine and a mold (not shown), and the intermediate body 170 is bent.

  FIG. 14 is an explanatory diagram showing a bending position with respect to the intermediate body 170. In the fifth step, bending is individually performed along the fold line 121 and the fold line 124. Alternatively, bending is performed simultaneously along the fold line 121 and the fold line 124. Further, bending is simultaneously performed along the fold line 122 and the fold line 123. Thereby, the skirt guard bracket 17 of FIG. 3 is completed.

  In such a skirt guard device 15, the upper angle 19 and the clip 20 are fixed to the panel back surface 18b. The skirt guard bracket 17 is formed with a bracket upper surface portion 17b and a lower contact portion 17e. And the upper angle protrusion part 19b is piled up on the bracket upper surface part 17b, and is fastened by the bracket upper surface part 17b with the angle fastener 23. FIG. Further, the lower contact portion 17e is sandwiched between the panel back surface 18b and the sandwiching portion 20b. For this reason, the number of parts can be reduced and the assembly efficiency can be improved.

  Moreover, separation of parts due to insufficient screw tightening force can be suppressed.

  Further, the fixing position of the skirt guard bracket 17 to the fixing plate 16 can be adjusted in the vertical direction. For this reason, assembly efficiency can be further improved.

  The skirt guard bracket 17 is formed with a lower contact portion 17e, and the lower contact portion 17e is in surface contact with the panel back surface 18b. For this reason, bending of the skirt guard panel 18 when a concentrated load is applied to the skirt guard panel 18 can be suppressed.

  The skirt guard bracket 17 is also formed with an upper contact portion 17d, and the upper contact portion 17d is also in surface contact with the panel back surface 18b. For this reason, the bending of the skirt guard panel 18 when a concentrated load is applied to the skirt guard panel 18 can be further suppressed.

  An upper angle 19 and a lower angle 24 are fixed to the skirt guard bracket 17. For this reason, the bending of the skirt guard panel 18 when a concentrated load is applied to the skirt guard panel 18 can be more reliably suppressed.

  In Embodiment 1, for example, when a concentrated load of 1000 N is applied to the skirt guard panel 18, the amount of deflection of the skirt guard panel 18 can be set to 5.0 mm or less. Moreover, the residual displacement at the time of unloading 1000N concentrated load can be 0.5 mm or less.

  Further, the outer shape of the intermediate body 170 is symmetric about the center line C. For this reason, the intermediate body 170 can be made common on both sides of the step 2.

  Further, the intermediate body 170 is provided with a convex portion 170a and a concave portion 170b, and the width dimension β of the convex portion 170a is equal to or smaller than the width dimension α of the concave portion 170b. For this reason, a part of the outline of the intermediate body 170 can be shared, and the plate material 100 that is the raw material of the skirt guard bracket 17 can be reduced in weight. Moreover, the yield of the skirt guard bracket 17 can be improved.

  In addition, the laser irradiation time of the laser processing machine can be shortened. As a result, the production tact time can be shortened and the consumption of processing energy can be reduced.

  Further, a bracket long hole 17h is provided in the bracket upper surface portion 17b. For this reason, the fixing position of the skirt guard panel 18 can be easily adjusted, and the assembly efficiency can be further improved.

  If the strength of the skirt guard panel 18 is sufficient, the upper contact portion 17d and the lower angle 24 may be omitted.

  Further, the manufacturing procedure of the intermediate body 170 is not limited to the above example. For example, you may implement continuously from the 1st process to the 4th process for every row of FIG.
