本発明はワイヤカツト放電加工機の切断式ワイ
ヤ処理装置、特に放電後のワイヤの切断式ワイヤ
処理装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cutting type wire processing apparatus for a wire cut electric discharge machine, and particularly to a cutting type wire processing apparatus for a wire after discharge.

後のワイヤを巻取る形式のものである。 A wire cut electrical discharge machine uses a wire as a tool electrode, and while controlling the relative position of the wire and the workpiece, generates an electrical discharge between the wire and the workpiece to cut the workpiece. Wires need to be handled. Currently, the most commonly used method is the one shown in the first example, in which the wire after discharge is wound up using a take-up reel.

る。 The configuration of a conventional winding type wire processing device will be explained below with reference to FIG. The wire 12 fed out from the supply reel 10 is guided by the guide roller 14, passes through the machined groove 18 of the workpiece 16, passes between the take-up roller 20 and the pinch roller 22, and is further wound around the alignment reel 24. After that, it is wound onto a take-up reel 26. The side plate 28 of the take-up reel 26 is configured to be detachable using a tightening nut 30.
Engagement recess 3 for hooking the wire 12 on the side plate 28
2 and a leaf spring 34 is provided to fix the wire end thereof. The alignment reel 24 is reciprocated in the direction of an arrow 38 by an alignment winding device 36, causing the take-up reel 26 to wind the wires 12 in an aligned state. Further, the support body 40 of the pinch roller 22 is provided with an adjustment screw 42 for adjusting the pressing force between the take-up roller 20 and the pinch roller 22.

ローラ２２間にはさみ込んでセツトする。 Next, the operation of the conventional device having the above configuration will be explained. When the supply reel 10 rotates and feeding of the wire 12 begins, the take-up reel 26 rotates in the direction of the arrow, and the alignment reel 24 is driven by the alignment winding device 36 to reciprocate in the direction of the arrow. The wire 12 is wound onto a take-up reel 26 in an aligned manner. Also, during processing, the take-up reel 26
When the wire 12 is full, the machining is interrupted, the nut 30 and the side plate 28 are removed from the take-up reel 26, and the wire 12 that has been wound and discharged is transferred to the take-up reel 2.
Remove from 6. This operation is performed even when machining a new workpiece 16, even if it is not currently being machined. After these operations, the tip of the new wire 12 is sandwiched between the side plate 28 and the leaf spring 34 and fixed to the take-up reel 26, and the middle of the wire 12 is wound around the alignment reel 24, and then the wire 12 is wound. It is inserted between the take-up roller 20 and the pinch roller 22 and set.

る。 In addition, if the wire 12 is broken due to an abnormal situation during machining, or if the same workpiece is being machined multiple times (for example, progressive type machining), in order to move the workpiece to a new machining position, one When it becomes necessary to cut wires, the broken wires or the cut wires are tied together manually.

より行なうため手間がかかる等の欠点があつた。 However, in the conventional device having the above configuration, after the wire 12 is broken due to an abnormal situation during processing or the wire is cut when multiple pieces are processed on the same workpiece, the supply of the wire 12 is automated and unmanned operation is performed. This poses a major obstacle. Furthermore, even if the wire 12 is disconnected or the wire connection after cutting is automated, when the take-up reel 26 is full of wires 12 (for example, during long-term continuous processing), processing is interrupted and unnecessary wires 12 are removed. There were drawbacks such as the fact that the removal was done manually, which took time and effort.

がより確実である。 Next, the operation of one embodiment of the present invention having the above configuration will be explained with reference to FIGS. 5 and 6. When the drive motor 46 is operated at the same time as the wire cut electric discharge machining starts, the driven shaft 52 receives a rotational force via the drive shaft 48 and gears 54 and 56, and the cutter 44 and roller 50 rotate in synchronism in the direction of the arrow. On the other hand, the discharged wire 12 is fed between the cutter 44 and the roller 50 by a wire conveying means (not shown) (for example, the wire 12 is fed between a belt or rollers). The fed wire 12 is cut into cutting blades 44a, 44b, as the cutter 44 and roller 50 rotate.
44c, 44d, 44e and protrusions 50a, 50
b, 50c, 50d, and 50e, and is conveyed while being bent. Here protrusion 50
The tips of a to 50e are formed into, for example, a round shape so that they do not act as cutting edges. At this time, the cutting blade 4
4d, the protrusion 50c, the cutting blade 44d, and the protrusion 5
If the gaps 64 and 66 that occur at 0d are set to the diameter of the wire 12 or slightly smaller than the diameter of the wire 12, the wire 12 will be restrained by the gaps 64 and 66 and will be in a tensioned state, that is, a state in which the wire 12 can be easily and reliably cut. become. And in the case of Figures 5 and 6,
The wire 12 is cut by the cutting edge of the cutting blade 44d.
Therefore, as shown in FIG. 6, when the cutting edge of the cutting blade 44d cuts the wire 12, the gap 68 created between the cutting edge of the cutting blade 44d and the roller 50 is made to be slightly smaller than the diameter of the wire 12. It is more reliable to do so.

るものである。 The wire pieces 12a cut one after another by the above operation are sent downward by the rotation of the cutter 44 and the roller 50 and fall into the storage case 62. Further, during the above operation, the cutter 44 and the roller 50 are rotated synchronously so as to keep the gaps 64 and 66 constant.

In between, there are protrusions 50b', 50c', 50e', which are the same as the protrusions provided around the entire circumference of the roller 50.
50f' is provided. According to this embodiment, the length of the cutting wire piece 12a' is three times as long as in the previous embodiment.

る。 As described above, since the present invention continuously cuts the wire after discharge, wire breakage or wire supply after cutting can be automated, and therefore unmanned operation can be carried out. It is extremely effective as a wire processing device. In addition, when the wire after discharge is wound on the take-up reel, when the wire is fully wound on the take-up reel, there is no disadvantage in that processing must be interrupted and the wire must be removed from the take-up reel. do not have. Therefore, wire cut electrical discharge machining can be performed continuously until the end of machining, and machining efficiency can be improved.
