The manufacture method of the bending part 10 that following explanation is formed thus.
First, prepare to form the steel plate 100 that top view is rectangle as shown in dotted lines in Figure 12.
This steel plate 100 has opposed a pair long leg 102,102 of the opposed pair of short edges portion of X along its length 101, the 101 width Y vertical with length direction X with edge.
Then, recess formation process is implemented.
From the substantially central portion of the length direction X of the long leg 102 of steel plate 100 in the width direction Y shape become recess 110.In present embodiment, recess 110 is formed by with lower part: tilt relative to long leg 102 and a pair first wall portion 111,111 separately formed at length direction X; A pair second wall portion 112 extended from the end of the first wall portion 111 to width Y; By the 3rd wall portion 113 that is connected to each other for the end of a pair second wall portion 112,112 and that extend to length direction X.
In addition, upper protuberance 22C, 32C, middle protuberance 22D, 32D and lower protuberance 22E, 32E is formed along long leg 102.The first protuberance 22F and the second protuberance 32F is formed in the mode that the surface back side from steel plate 100 is outstanding.In addition, the first stop hole 21B as through hole is worn at steel plate 100.
Thus, by steel plate 100 alongst X manufacture processing steel plate (parts) 109, described processing steel plate is formed with part i.e. the first steel plate portion (expanding portion) S1 and the second steel plate portion (expanding portion) S2 that do not form recess 110 and namely the part being formed with recess 110 links steel plate portion (narrow width part) R.
This link steel plate portion R is formed in the central authorities of length direction X, the width relative narrower of width Y.In addition, the first steel plate portion S1 and the second steel plate portion S2 is arranged on the both sides of the link steel plate portion R of length direction X, and compared with link steel plate portion R, the width of width Y is relatively wide.
Then, the first bending operation (main part formation process) is implemented.
Namely, the ratio in the first steel plate portion S1 of processing steel plate 109 and the second steel plate portion S2 is linked the more outstanding part bending Formation cross-section U-shaped of steel plate portion R.
Specifically, in the first steel plate portion S1 and the second steel plate portion S2 of processing steel plate 109, along parallel with long leg 102 two imaginary line P, P bendings, make long leg 102,102 opposed each other.In present embodiment, imaginary line P is positioned on the extended line of the bearing of trend of the 3rd wall portion 113.Carry out paddy folding along these two imaginary lines P, P, make the first steel plate portion S1 and the second steel plate portion S2 Formation cross-section view U-shaped respectively.
Then, the second bending operation (main part formation process) is implemented.
Namely, by the link steel plate portion R bending at processing steel plate 109, the first foot 20 and the second foot 30 is made to have compartment of terrain arranged opposite.
Specifically, at the link steel plate portion R of processing steel plate 109, along many imaginary line Q1, the Q2s parallel with short leg 101, to the direction bending contrary with the wrap direction of the first bending operation.In present embodiment, imaginary line Q1, Q1 are positioned on the extended line of the bearing of trend of the second wall portion 112, and imaginary line Q2 is positioned at the centre of the length direction X of two imaginary lines Q1, Q1.Peak folding is carried out along above-mentioned three imaginary lines Q1, Q1, Q2.
Peak folding is carried out relative to the tilt mode of 60 ° of the first steel plate portion S1 (the second steel plate portion S2) along imaginary line Q1 to link steel plate portion R.In addition, the mode of intersecting with 120 ° each other with the back side (the paper back side shown in Fig. 9) linking steel plate portion R carries out peak folding along imaginary line Q2.
Thus, in the first steel plate portion S1, more each imaginary line P becomes the first side wall portion 22 of the first foot 20 closer to the part of end side.In addition, in the first steel plate portion S1, the part being supposed to line P, P clamping becomes the first bottom wall part 21 of the first foot 20.
In second steel plate portion S2, form the second sidewall portion 32 and the second bottom wall part 31 of the second foot 30 similarly.
In addition, in link steel plate portion R, the part being supposed to the first S1 side, steel plate portion in the part of line Q1 and Q2 clamping becomes the first curved wall portion 41 of linking part 40.In link steel plate portion R, the part being supposed to the second S2 side, steel plate portion in the part of line Q1 and Q2 clamping becomes the second curved wall portion 42 of linking part 40.
In other words, by processing steel plate 109 being bent into the U-shaped of short leg 101 side opening, the bending part 10 with the first foot 20, linking part 40, second foot 30 is formed.
Then, separator formation process is implemented.
