  Some workpieces made of wire form not only a vertical hole in the axial direction but also a horizontal hole in a direction perpendicular to the axial direction. However, with conventional wire rod processing equipment, it was not possible to drill vertical and horizontal holes at the same time, so the vertical and horizontal holes must be formed separately by the two processing equipment, and that much equipment. Costs and labor are required, productivity is not increased, and costs are high.

  Therefore, an object of the present invention is to provide a wire rod processing apparatus and a wire rod processing method capable of forming a vertical hole and a horizontal hole together.

  The wire rod processing apparatus according to the present invention includes a stage for making a vertical hole in a wire with a punch and a die, a stage for making a horizontal hole in the wire with a punch and a die, and an upstream chucking the wire to a finger. A transport unit for transporting the die from the downstream die to a downstream die, and an entrance hole into which a punching pin held by a punch of the downstream stage enters a finger of the transport unit for transporting the wire to the downstream die. A horizontal rotating means for horizontally rotating the fingers by 90 ° is provided, and the lateral holes are formed by horizontally rotating the fingers by 90 ° to allow the drilling pins to enter the holes.

  A wire rod processing apparatus according to the present invention includes a ram having a punch, a die block having a die opposed to the punch, advancing and retreating means for advancing and retreating the ram relative to the die block, and a wire rod as a finger. A wire rod processing apparatus including a conveyance unit that chucks and conveys from an upstream die to a downstream die, and the upstream punch and die form a vertical hole in the axial direction in the wire. A horizontal rotation means for horizontally rotating the finger of the transport unit that has received the wire with the hole formed therein by 90 ° is provided, and an entry hole into which a punching pin held by the punch enters is formed in the finger. A horizontal hole is formed in the wire in which the vertical hole is formed by a pin for opening.

  The wire rod processing method of the present invention includes a ram having a punch, a die block having a die opposed to the punch, advancing and retreating means for advancing and retreating the ram relative to the die block, and a wire rod as a finger. There is a transport unit that chucks and transports from the upstream die to the downstream die. The upstream punch and die form a vertical hole in the axial direction in the wire, and then the transport receives the wire with the vertical hole formed. After the fingers of the unit are horizontally rotated by 90 ° by the horizontal rotation means, the drilling pins held by the punches are inserted into the entrance holes formed in the fingers, and the vertical holes are formed by the drilling pins. A horizontal hole is formed in the formed wire.

  According to the present invention, the finger of the transport unit that has received the wire having the vertical hole is rotated 90 ° horizontally, and the horizontal hole is made by entering the drilling pin into the entrance hole formed in the finger. Therefore, the vertical hole and the horizontal hole can be formed with good workability by one processing apparatus.

  Next, embodiments of the present invention will be described with reference to the drawings. Fig.1 (a) is a perspective view of the workpiece | work manufactured with the processing apparatus of the wire in one embodiment of this invention, FIG.1 (b) is the same sectional drawing. In FIG. 1, a workpiece 1 is a pipe, and a first hole 2 and a second hole 3 which are vertical holes are formed as communication holes in the axial direction thereof. A lateral hole 4 is formed in the body portion.

  FIG. 2 is an overall side view of the wire rod processing apparatus 10. A flywheel 12 is provided on one side of the base 11. The flywheel 12 is driven by the motor M and the belt 13 to rotate. A ram 14 is connected to the flywheel 12. A punch 15 is provided on the front surface of the ram 14. A die block 17 is provided on the upper portion of the frame 16 on the other side of the base 11. The die block 17 is provided with dies 18 (181 to 186) facing the punches 15 (151 to 156) provided on the ram 14. When the motor M is driven, the flywheel 12 rotates and the punch 15 moves forward and backward relative to the die block 17 (see arrow a). That is, the motor M, the flywheel 12 and the belt 13 serve as a forward / backward means for the ram 14. Further, on the front surface of the die block 17, fingers f1 and f2 of a transport unit (described later) for transporting the wire material to be the workpiece 1 from the upstream stage to the downstream stage are located.

  FIG. 3 is a plan sectional view of the ram 14 and the die block 17 and has a plurality of (six in the present embodiment) stages S1 to S6 from upstream to downstream where the wire 1 is conveyed. Each of the stages S1 to S6 is provided with a plurality of punches 151 to 156 and dies 181 to 186 facing each other.

  The first punch 151 and the first die 181 of the first stage S1 perform end face correction of the wire 1 cut to a predetermined length at a cutting stage S0 (described later) upstream of the first stage S1. The second punch 152 and the second die 182 of the second stage S2 perform the first drilling (drilling the first hole 2). The third punch 153 and the third die 183 of the third stage S3 perform the second drilling (drilling the second hole 3). The fourth punch 154 and the fourth die 184 of the fourth stage S4 perform dregs removal (finishing in the holes of the first hole 2 and the second hole 3) after drilling. The fifth punch 155 and the fifth die 185 of the fifth stage S5 perform serration processing for attaching knurled eyes or the like to a part of the outer periphery of the wire 1. The sixth punch 156 and the sixth die 186 of the sixth stage S6 open the lateral hole 4 by a method described later.

  The punches 151 to 156 hold pin-shaped jigs 191 to 196 for processing the wire 1 and forming the workpiece 1. Among these, the punches 152 and 153 of the upstream stages S2 and S3 hold pins 192 and 193 which are drilling jigs for drilling the first hole 2 and the second hole 3 which are vertical holes, and are located downstream. The punch 156 of the stage S6 holds a pin 196 that is a drilling jig for making the horizontal hole 4.

  FIG. 4 is a front view of the die block 17, in which a cutting stage S0 and first to sixth stages S1 to S6 are provided in order from upstream to downstream (from left to right in FIG. 4). The cutting stage S0 chucks the wire led out from the spool (not shown) on the fingers f1 and f2 of the transport unit 201 and cuts the wire into a predetermined length by a cutter (not shown) to obtain the wire 1. Each transport unit 20 (201 to 206) chucks the wire 1 from the left and right by a pair of left and right fingers f1 and f2 provided at the lower part thereof, and transports the wire 1 from the upstream stage to the downstream stage.

  That is, the first transport unit 201 transports the wire 1 cut to a predetermined length in the cutting stage S0 to the front surface of the die 181 of the first stage S1, and the second transport unit 202 transmits the finger f1, The wafer is chucked at f2 and subjected to edge correction. Next, the wire 1 is conveyed from the first stage S1 to the front surface of the die 182 of the second stage S2, and the first hole 2 is opened. Subsequently, the wire 1 is conveyed to the front surface of the die 183 of the third stage S3, and the second hole 3 is opened. Next, it is sent to the front surface of the die 184 of the fourth stage S4 to perform residue removal, and then sent to the front surface of the die 185 of the fifth stage S5 to perform serration. The most downstream transport unit 206 receives the wire rod 1 chucked by the fingers f1 and f2 from the upstream transport unit 205 and transports it from the fifth stage S5 to the sixth stage S6. At this time, the fingers f1 and f2 of the transport unit 206 are rotated 90 degrees horizontally by the horizontal rotation means 30 to change their directions (see arrow b). FIGS. 5A and 5B show the state of horizontal rotation in the stages S5 and S6.

  Next, the horizontal rotation means 30 will be described with reference to FIGS. Fingers f <b> 1 and f <b> 2 are attached to the lower part of the vertical rotation shaft 206 a of the transport unit 206. A fan-shaped gear 31 is attached to the upper portion of the rotating shaft 206a. A gear 32 is disposed between the fifth stage S5 and the sixth stage S6. The gear 31 meshes with the gear 32, and the gear 31 rotates along the gear 32 while the transport unit 206 moves from the fifth stage S5 to the sixth stage S6 (arrow b in FIG. 6B). As shown in FIG. 5A, the rotating shaft 206a and the fingers f1 and f2 rotate 90 ° horizontally. As a result, the wire 1 chucked by the fingers f1 and f2 is moved in the direction parallel to the front surface of the die 186 shown on the right side of FIG. 5A from the axial direction of the die 185 shown on the left side of FIG. ° Change direction.

  In FIG. 5A, the punch 156 of the sixth stage S <b> 6 holds a drilling pin 196 that is a jig for drilling the lateral hole 4. The finger f1 is formed with an entry hole A into which the drilling pin 196 enters. Therefore, when the wire 1 chucked by the fingers f1 and f2 of the downstream transport unit 206 is transported from the fifth stage S5 to the sixth stage S6, the fingers f1 and f2 are turned 90 ° by the horizontal rotation means 30. In stage S6, the entrance hole A faces the pin 196. Therefore, as shown in FIG. 5B, when the ram 14 moves forward (arrow c), the pin 196 enters the entry hole A and opens the lateral hole 4. When the work for opening the vertical holes 2 and 3 and the horizontal hole 4 is completed as described above and the work 1 is completed, the fingers f1 and f2 are opened, and the work 1 falls downward and is collected by a predetermined collecting part. .

  According to the present invention, the finger of the transport unit that has received the wire having the vertical hole is rotated 90 ° horizontally, and the horizontal hole is made by entering the drilling pin into the entrance hole formed in the finger. Therefore, it is possible to form both vertical holes and horizontal holes with good workability with a single processing device. Therefore, in particular, a wire processing device and a processing device for drilling vertical holes and horizontal holes from wires such as steel wires. Useful as a method.
