The bending device includes a piston 1, a cutting tool 2 including a movable cutter 3 and a fixed cutter 4 for cutting a metal wire, a movable bending tool 6 for bending an end of the metal wire after cutting, and a fixing tool. The folding tool 5 includes the folding tool 7, and the work holding metal fitting 8 and the like. The piston 1 is in the shape of a regular quadrangular prism, and guide rollers (not shown) are attached to the upper, lower, left and right side surfaces of the piston 1, and the piston 1 extends and moves in the leftward direction in FIG. 1 via a drive source (not shown). It is designed to perform a forward movement and a backward movement in which it retracts to the right in FIG. As shown in FIG. 5 (a perspective view of the cutting tool 2), the cutting tool 2 is composed of a pair of a moving cutter 3 and a fixed cutter 4, and one moving cutter 3 has a metal wire on its upper side surface. A step 3a for mounting and holding and a blade 3b are formed along the substantially vertical upper side, respectively, and are attached to a right frame 12 of a support base 11 attached to one end of the piston 1. There is. On the other hand, the fixed cutter 4 has a blade portion 4b formed along a substantially vertical lower side thereof, and is attached to a lower portion of a base 20 fixedly installed on a base (not shown). The fixed cutter 4 is arranged on the front side of the base 20 with respect to a fixed bending tool 7 which will be described later, and cuts the metal wire before starting the bending. The movable cutter 3 and the fixed cutter 4 are arranged in such a positional relationship that the respective blade portions 3b, 4b can rub each other. As shown in FIG. 6 (a perspective view of the folding tool 5), the folding tool 5 is composed of a pair of a moving folding tool 6 and a fixed folding tool 7, and one of the moving folding tools 6 is A step 6a for mounting and holding the metal wire is formed on the upper side thereof. Further, as shown in FIG. 7 (rear view of the movable bending tool 6) on the back side, a restricting portion 6b for restricting the bending direction of the metal wire, and in this embodiment, from the position of the step 6a to the lower side A step is provided at a predetermined inclination angle θ (for example, an inclination angle of 60 degrees) toward the side so that the bending direction is directed to the inside of the coil bundle. The movable bending tool 6 is provided on the left frame 13 of the support 11 in parallel with the movable cutter 3 at an appropriate interval to secure the bending allowance of the metal wire. On the other hand, the fixed bending tool 7 is formed with a sloped portion 7a inclined from the front end to the rear end of its lower side in order to bend the metal wire by pushing it down. The fixed bending tool 7 is located at the lower portion of the base 20 at a position corresponding to the moving path of the moving bending tool 6, and as described above, it is bent to cut the metal wire and then bend it. It is installed behind the fixed cutter 4. The support base 11 is provided with a slit 14 between the piston 1 and the movable bending tool 6 for dropping and discharging the metal wire. The work-holding metal fitting 8 is for pressing the metal wire so as to more reliably cut and bend the metal wire during the cutting process and the bending process, and is shown in FIG. 8 (a perspective view of the work-holding metal fitting 8). As shown, the lower side 8a is formed to be partially inclined to smoothly guide the metal wire, and the lower side surface is corrugated. The work holding metal fittings 8 are respectively connected to three spring type plungers 24 provided on the base 20, and the lower side of the work holding metal fittings 8 is repulsed by a spring (not shown) housed in a cylinder 24a of the plunger 24. A metal wire is brought into contact with 8a and pressed downward.

Next, the operation of the metal wire cutting and bending apparatus having the above structure will be described with reference to the drawings. Note that FIG. 9 shows a state before the use of the device, and FIGS. 10 to 13 illustrate the use state of the device. FIG. 10 is a step of placing a metal wire, and FIG. 11 is a cutting of the metal wire. The process, FIG. 12 shows the bending process of the metal wire, and FIG. 13 shows the discharging process of the metal wire. In each drawing, (a) is a front view and (b) is a plan view. First, the metal wire 30 sent out in a spiral shape is guided by the guide tool 31 and is sequentially bundled in a coil shape on a carrier (not shown) (FIG. 9). When this coil becomes a predetermined bundle, the feeding of the metal wire 30 is temporarily stopped, and the piston 1 is moved forward to extend to the left. By this forward movement, the metal wire 30 is placed on the steps 3a and 6a of the movable cutter 3 and the movable bending tool 6 (the mounting process diagram of FIG. 10), and then the piston 1 is retracted to perform the backward movement. As a result, the metal wire 30 is moved to the right in the installed state. In this case, as shown in FIG. 10, at the same height position as the step 3a of the moving cutter 3 on the outside of the right frame 12, the detection sensor 40 of the contact conduction type or the like having the terminals 40a and 40b is mounted. Then, the metal wire is placed on the step 3a, and both terminals 40a and 40b (or the terminal 40b is omitted, the right frame 12 grounded to the terminal 40a) is brought into contact with the terminal 40a for conduction (voltage or current). When the change sensor 40 detects the change, the backward movement operation of the piston 1 may be started. In the returning process of the piston 1, the metal wire 30 abuts against the lower side 8a of the work holding metal fitting 8 at one position thereof and is pressed by the lower side 8a, whereby the metal wire 30 is restrained and held on the steps 3a and 6a. In this state, as the piston 1 further moves back, the metal wire 30 is scraped and cut by the blade portions 3a and 4b of the movable cutter 3 and the fixed cutter 4 (cutting process diagram of FIG. 11). Further, as the return movement of the piston 1 continues, the ends of the metal wire 30 cut as described above are sequentially pushed down along the sloped portion 7a of the fixed bending tool 7, and the rear surface of the moving bending tool 6 is depressed. The bending process is completed by bending in the direction along the regulating portion 6b (shown in FIG. 7) formed on the inner side of the coil bundle, that is, the bending process is completed (the bending process diagram in FIG. 12). When the bending process of the metal wire 30 is completed, the piston 1 starts the forward movement of extending leftward again. Then, since the metal wire 30 is pressed in contact with the lower side 8a of the work pressing metal fitting 8 in this forward movement process, the end of the metal wire 30 slides on this upper side surface as the movable bending tool 6 moves. However, it is detached from here, and then, when it coincides with the point of the slit 14 provided in the support base 11, it is dropped and discharged from here (discharge process diagram of FIG. 13). After that, the piston 1 returns to the original state shown in FIG. As described above, in the metal wire cutting and bending apparatus of this example, the metal wire 30 is scraped and cut by the movable cutter 3 and the fixed cutter 4, and the terminal after cutting is moved. Since the fixed bending tool 7 can bend the coil bundle inward, it is possible to form the coil bundle in a state where this terminal can be easily found. In the first embodiment, the movable cutter 3 and the movable bending tool 6 are moved by reciprocally moving the support base 11 via the piston 1, but instead of this, the base 20 is replaced. Alternatively, the fixed cutter 4 and the fixed bending tool 7 may be configured to move reciprocally. Further, the cutting tool 2 can cut the metal wire by using, for example, a laser beam irradiation device or the like instead of the pair of moving cutter 3 and fixed cutter 4.

Next, a second embodiment of the present invention will be described. 14 is a front view and a plan view of the apparatus, and FIG. 15 is a view showing a detached state of the metal wire. In these drawings, the same reference numerals are given to the members corresponding to those in FIGS. 2, 3 and 12. Is attached and the description thereof is omitted. In this embodiment, a work push-out fitting 9 is installed in addition to the structure of the first embodiment. That is, the work push-out fitting 9 is arranged right above the moving path of the movable bending tool 6, and is connected to the plunger 24 similarly to the work holding fitting 8, so that the work push-out fitting 9 can be moved and folded. The upper side surface of the bending tool 6 can move while contacting. Therefore, the work push-out fitting 9 rides up along the step 6a of the movable bending tool 6 shown in FIG. 6 in the returning process of the piston 1 from the cutting of the metal wire 30 to the terminal bending step. On the other hand, in the forward movement process of the piston 1 after the bending process of the metal wire 30, it slides down along the step 6a of the movable bending tool 6. Therefore, the end of the metal wire 30 which is restrained and held by the step 6a stops in a state of being in contact with the side surface 9a of the work push-out fitting 9 (Fig. 15), and then as the moving bending tool 6 moves, Be separated from. After that, as in the case of the first embodiment, the metal wire 30 is dropped and discharged at the time when the metal wire 30 is aligned with the slit 14. As described above, the work push-out fitting 9 allows the end of the metal wire 30 to be more reliably detached from the moving bending tool 6 than in the case of the first embodiment.
