As shown in FIG. 3, the air supply device 60 includes a blower 61, an air introduction chamber 62 connected to the blower 61 via a blower duct (not shown), and an air supply path 64 that supplies air along the seating surface 44. And a curved path 66 that guides the air introduced into the air introduction chamber 62 to the air supply path 64. The air supply path 64 drives the blower 61 to introduce air into the air introduction chamber 62, thereby supplying air from the air introduction path 62 through the curved path 66 and the air supply path 64 in this order. The air supply path 64 is a concave groove that opens upward, and extends so as to be on the same straight line as the seating surface 44 (concave portion 46) while being at the same height level as the seating surface 44 of the die 40. It has been issued. The curved path 66 is a passage smoothly connected to the upstream end of the air supply path 64 by a convex curved surface, and the air guided from the curved path 66 to the air supply path 64 supplies air while entraining the upper outside air by the Coanda effect.

The air suction device 70 sucks air around the extending end portion of the seating surface 44 through the pair of insertion holes 41 and 42 by driving the dust collector 71 to apply a negative pressure to the air suction chamber. As a result, the air supplied from the air supply device 60 flows along the seating surface 44 (recessed portion 46) and then is sucked by the air suction device 70 from the pair of insertion holes 41 and 42. Therefore, when the processing waste (foreign matter) generated by the processing of the flat wire D remains on the seating surface 44, the processing waste can be sucked together with the air by the air suction device 70 (dust collector 71).

Next, the operation of the work processing apparatus 20 configured in this way will be described. FIG. 5 is an explanatory view showing a state of the work processing device 20 when the punch is raised, and FIG. 6 is an explanatory view showing a state of the work processing device 20 when the punch is lowered. The flat wire D is carried in by a carry-in device (not shown) so that the tip surface abuts on the abutting surface 48a of the positioning block 48 while being seated on the seating surface 44 of the die 40, and is shown when the processing (peeling of the insulating film) is completed. Not carried out by a carry-out device. First, when the flat wire D is carried in by the transfer device, the work processing apparatus 20 raises the die 40 and lowers the clamper 50, and the clamp 54 presses the clamper 50 to bring the flat wire D onto the seating surface 44 of the die 40. Hold down and clamp. Subsequently, the pair of punches 31 and 32 are machined by penetrating the pair of guide holes 51 and 52 of the clamper 50 and lowering the pair of punches 31 and 32 so as to be inserted into the pair of insertion holes 41 and 42. The blades 33 and 34 cut the side surface of the flat wire D on the short side. As a result, the insulating film on the side surface of the flat wire D is peeled off. Next, the pair of punches 31, 32 and the clamper 50 are sequentially raised so as to be separated from the die 40 to release the clamp of the flat wire D, and the flat wire D is carried out from the seating surface 44 of the die 40 by the conveying device. .. Then, the elevating position of the die 40 is adjusted so that the air supply path 64 of the air supply device 60 is on the same straight line as the seating surface 44 (recessed portion 46), and the elevating position of the die 40 is adjusted from the air supply path 64 toward the seating surface 44. Blow out air.

FIG. 7 is an explanatory diagram illustrating a flow of air for removing work chips. In the work processing apparatus 20 of this embodiment, the blower 61 and the dust collector 71 are constantly driven. As shown in the figure, the air introduced from the blower 61 into the air introduction chamber 62 is guided to the air supply path 64 via the curved path 66. Since the curved path 66 is smoothly connected from the air introduction path 62 to the upstream end of the air supply path 64 by a convex curved surface, the air passing through the curved path 66 flows along the air supply path 64 due to the Coanda effect, and the air flows. It is supplied to the seating surface 44 from the supply path 64 toward the seating surface 44. Since the seating surface 44 extends in the same straight line as the air supply path 64, the air supplied to the seating surface 44 flows along the seating surface 44 in the extending direction, and the pair of insertion holes 41, It is sucked by the air suction device 70 via 42. As a result, foreign matter such as machining debris generated by the machining (cutting) of the flat wire D is collected by the dust collector 71 through the pair of insertion holes 41 and 42 on the air flow, and is collected by the dust collector 71. When processing D, it is possible to prevent foreign matter from adhering to the flat wire D.

According to the work processing apparatus 20 of the present embodiment described above, the air supply path 64 that supplies air from the base end portion of the seating surface 44 that extends linearly in the extending direction and the air supply path 64 by the convex curved surface. An air supply device 60 having a curved path 66 that is smoothly connected to the upstream end of the blower 61 and guides the air from the blower 61 to the air supply path 64, and a pair of insertion holes 41 for inserting the air around the extending end of the seating surface 44. , 42 is provided with an air suction device 70 for sucking. The air from the blower 61 is guided to the air supply path 64 through the curved path 66, flows from the base end portion of the seating surface 44 along the extending direction by the Coanda effect, and reaches the extending end portion of the seating surface 44. After reaching, it is sucked into the pair of insertion holes 41 and 42. As a result, the processing debris (foreign matter) remaining on the seating surface 44 due to the processing of the flat wire D can be removed more appropriately.

In the work processing device 20 of the embodiment, the blower 61 of the air supply device 60 and the dust collector 71 of the air suction device 70 are constantly driven, but the present invention is not limited to this, and the required timing (for example, flat angle) is not limited to this. It may be driven intermittently at the timing when the processing of the wire D is completed and carried out).

In the work processing device 20 of the embodiment, by providing the air supply device 60 and the air suction device 70, the processing debris (foreign matter) remaining on the seating surface 40 due to the processing of the flat wire D is removed. However, it may be provided with a configuration for removing the machining debris adhering to the machining blades 33 and 34 of the punches 31 and 32. FIG. 8 is a cross-sectional view of a work processing apparatus 120 of a modified example, and FIG. 9 is an explanatory view illustrating a flow of air for removing processing debris (foreign matter) adhering to the processing blade 33. The workpiece processing device 120 of the modified example is said to have the outside air hole 145 extending from one insertion hole 41 of the die 140 in a direction orthogonal to the insertion hole 41 and communicating with the outside air, and the other insertion hole 42 of the die 140. It has an outside air hole (not shown) extending in a direction orthogonal to the insertion hole 42 and communicating with the outside air. As shown in FIG. 9, when the side surface of the flat wire D is cut while the punch 31 descends and is inserted into the insertion hole 41, the opening above the insertion hole 41 is closed at the descending end of the punch 31. .. At this time, if a negative pressure is applied to the air suction chamber by driving the dust collector 71, the outside air is taken in from the outside air hole 145 that communicates with the air suction chamber through the insertion hole 41. As a result, the flow of outside air (air) from the outside air hole 145 to the air suction chamber through the insertion hole 41 gives a physical force to the work chips adhering to the work blade 33 of the punch 31 to drop the work chips. It can be collected by the dust collector 71. Similarly, the outside air is also taken in from the outside air hole communicating with the insertion hole 42, and adheres to the processing blade 34 of the punch 32 by the flow of the outside air from the outside air hole to the air suction chamber through the insertion hole 42. By applying a physical force to the work chips, the work chips can be dropped and collected by the dust collector 71.

In the embodiment, the present invention has been applied to cutting the insulating film on the side surface of the flat wire D, but the present invention is not limited to this, and for example, a linear workpiece such as chamfering the tip surface of the flat wire D is used. It may be applied to any material as long as it processes the end portion of the surface and removes the processing waste (foreign matter) generated by the processing.
