In this posture (hereinafter, referred to as “basic posture of the holding tool 35”), the opposing member 35B, 35B protrudes laterally in the horizontal direction (see FIG. 3A). When the holding tool 35 is set to this basic posture and the tool fixing unit 30 is rotationally driven by the second driving unit 22, the facing members 35 </ b> B and 35 </ b> B rotate about the central axis facing the feeding direction of the band plate material 90. Hereinafter, this is referred to as “twist the holding tool 35”. Further, when the tool fixing unit 30 is rotationally driven by the third driving unit 23, the entire holding tool 35 is turned around an axis orthogonal to the linear movement direction of the tool fixing unit 30. Hereinafter, this is referred to as “turning the holding tool 35”. Further, when the tool fixing unit 30 is directly moved by the first drive unit 21, the entire holding tool 35 is moved so as to approach or separate from the quill 14. Hereinafter, making the holding tool 35 approach the quill 14 by the first drive unit 21 is referred to as “advancing the holding tool 35”, and separating the holding tool 35 from the quill 14 is “retracting the holding tool 35. "

  The band plate material processing machine 10 is provided with a control unit (not shown) that performs NC control of each of the servo motors described above. Then, the control unit executes the NC program PG1 (see FIG. 8), so that a strip plate product W, which is a strip plate member 90 having a predetermined length and having a twist processing unit 91 described later, can be manufactured. Specifically, in the NC program PG1, the origin processing S10 (see FIG. 8) is performed, and as shown in FIG. 4A, all the tools 35, 36, 36, and 37 are moved to positions relatively far from the quill 14. The holding tool 35 is retracted and twisted by 90 ° from the basic posture so that the facing members 35B and 35B face downward (hereinafter referred to as “initial posture”). Then, a feeding process S11 (see FIG. 8) is performed, and the strip material 90 is fed by a predetermined length by the material feeding device 12.

Thereby, a part of the strip plate material 90 is sandwiched between the pair of opposing members 37B and 37B of the auxiliary tool 37, and movement in the plate thickness direction is restricted. Simultaneously with the advancement of the auxiliary tool 37, the entire holding tool 35 is turned so as to face obliquely downward. In this state, the holding tool 35 is advanced to the front of the auxiliary tool 37, and as shown in FIG. 4 (C), the holding tool 35 is inserted below the portion of the band plate material 90 that protrudes ahead of the auxiliary tool 37. Then, as shown in FIG. 5A, the holding tool 35 is turned in the opposite direction to return to the initial posture, and then further advanced. As a result, a portion of the band plate material 90 that protrudes forward from the auxiliary tool 37 is bent upward, and is sandwiched between the end surface of the holding tool 35 and the end surface of the auxiliary tool 37, and is bent at a right angle to the band plate material 90. A portion 92 is formed.

In this process, as shown in the change from FIG. 5A to FIG. 5B, the auxiliary tool 37 and the holding tool 35 are both retracted and the holding tool 35 is twisted so that the opposing members 35B and 35B are horizontally oriented. Then turn. Then, as shown in FIG. 5C, the holding tool 35 is advanced and then reversely rotated, and as shown in FIG. 6A, the base plate portion of the band plate material 90 that extends straight from the quill 14 is approached. The portion is received in the band plate material receiving space 35A of the holding tool 35 and sandwiched between the pair of opposing members 35B and 35B. At this time, a portion where the strip plate material 90 is exposed is left between the end face of the holding tool 35 and the end face of the quill 14 by a predetermined length.

  In this state, as shown in the change in FIG. 6A to FIG. 6B, the holding tool 35 is twisted 90 degrees. Thereby, the part exposed between the end surface of the holding | maintenance tool 35 and the end surface of the quill 14 among the strip | belt board materials 90 is twisted 90 degree | times, and the twist process part 91 is formed. At this time, since the turning axis of the holding tool 35 in the tool fixing portion 30 faces the horizontal direction, the holding tool 35 is moved around the turning axis facing the horizontal direction as shown in FIG. Swivel down and back.

  Next, a cutting process S14 (see FIG. 8) is performed. In this process, as shown in FIG. 7 (A), the strip plate material 90 is slightly fed, and then the cutting tools 36 and 36 are brought close to each other, as shown in the change from FIG. 7 (B) to FIG. 7 (C). Thus, the base end part on the quill 14 side is cut from the twisted part 91 of the band plate material 90. As a result, one strip product W, which is the strip plate 90 having a predetermined length and having the twisted portion 91, is completed. While cutting the strip 90, the holding tool 35 is turned to a horizontal posture as shown in FIGS. 7A to 7C, and the holding tool 35 is twisted by 180 ° to an initial posture. return. As described above, one cycle of the NC program PG1 is completed. By repeatedly executing the NC program PG1, a plurality of strip material products W can be manufactured continuously.

  As described above, according to the band plate material processing machine 10 and the method for manufacturing the band plate material product using the band plate material processing machine 10 according to the present embodiment, the band plate material 90 before being cut into a predetermined length is twisted, Since the strip material 90 is cut, a plurality of strip material products W can be efficiently and continuously manufactured as compared with the conventional method in which the strip material is previously cut to a predetermined length and then twisted. Further, by changing the posture and position of the holding tool 35 by the first to third driving units 21, 22, and 23 of the universal mechanism 20, the arbitrary position of the band plate material 90 is held and twisted in an arbitrary direction. be able to.

  Examples of the strip plate product W include a bus bar and a leaf spring used in an electric device.
