Description

[Detailed description of the invention] The present invention relates to a wire cutting device for a coiled wire accumulation facility, and its purpose is to cut the coiled wire into so-called half-cuts or from product wire by reliably cutting the coiled wire. The purpose is to effectively perform crop separation.

Examples thereof will be described below based on FIGS. 1 to 3.

As shown in FIG. 1, a coiled wire C coming out of a rolling mill (not shown) is turned into a spiral by a laying cone (not shown), and then cooled on an air-cooled conveyor 1. Transported while A centering cone 2 is vertically disposed at the end of the air cooling path, that is, the coiled wire supply path L. 1st
As is clear from FIGS. 2 and 2, the centering cone 2 has an annular recess 3 in its intermediate portion, and has a cylindrical body 4 that guides the coiled wire C falling from the wire supply path L to the centering cone 2. are arranged concentrically. Therefore, a falling path l for the coiled wire C is formed between the centering cone 2 and the cylindrical body 4. Support frame 5 and foundation 6 for cylinder body 4
Above, a pair of guide rails 7A, 7B are vertically installed on the left and right, and elevating bodies 8A, 8B are mounted on rollers 9A, 8B on each set of guide rails 7A, 7B.
Retained via 9B. Horizontal rails 10A, 10B are fixed to the elevating bodies 8A, 8B, and wire rod receiving members 11A, 11 are attached to the horizontal rails 10A, 10B.
B is supported via moving bodies 12A and 12B.
These moving bodies 12A, 12B are elevating bodies 8A, 8B.
It is interlocked and connected to forward/reverse movement mechanisms 13A and 13B provided in the. Also, wheel bodies 14A, 15A, 14B, 15B are pivotally supported at the upper and lower end portions of the pair of guide rails 7A, 7B, respectively, and these upper and lower wheel bodies 14A, 15A, 14B, 15B
One end and the other end of the cable bodies 16A, 16B wound around are connected to the elevating bodies 8A, 8B. Either one of the upper and lower wheels 14A, 15A, 14B, 15B is connected to a drive motor (not shown) via a reduction gear. Note that the wire rod receiving members 11A and 11B shown in FIG. 1 are shown in a state where their arrangement positions are displaced by 90 degrees in the horizontal direction from the actual positions. A pair of left and right transverse rails 17 are arranged below the centering cone 2, and a bogie 18 is supported by the transverse rails 17. A fixed frame 19 is provided directly below the centering cone 2 and below the transverse rail 17, and an upward cylinder device 20 and a vertical guide device 21 are provided on this fixed frame 19, and a support frame 22 is provided on this guide device 21. It is engaged so that it can be raised and lowered. The operating end 20A of the cylinder device 20 is connected to the support frame 22. With this configuration, the base plate 22A of the support frame 22 is connected to the transverse rail 17.
It is possible to go up and down between the upper and lower levels. In addition, the cylinder device 20, the vertical guide device 21, the support frame 2
2 lifts and lowers the accumulating mandrel 23
is configured. On the other hand, the wire splitting device 2 is attached to the cylindrical body 4.
5 and a wire cutting device 26 are provided. The wire splitting device 25 includes a splitting rod 27A that moves in and out of the upper part of the wire falling path l around the centering cone 2 from four directions, and a moving device 27B thereof.
an upper dividing device 25A, a swinging claw 28B that swings around the vertical axis 28A and moves in and out of the annular recess 3 from four directions, and a swinging drive device (not shown). The lower dividing device 25B consists of
Equipped with. Note that a plurality of swinging protruding and retracting claws 28B are provided at equal angles (four in the illustrated example) (dotted chain line in FIG. 3), but these are linked by a link mechanism (not shown).
They are made to interlock with each other. As is clear from FIG. 3, the wire cutting device 26 has vertical shafts 29 supported at four equiangularly spaced locations around the cylindrical body 4, and plate links rotatably supported on these vertical shafts 29. 30, a claw claw 31 integrated into the plate link 30 at its base end, and a rod link 3 that interconnects each plate link 30.
2, a swing drive device 33 interlockingly connected to one of the plurality of plate links 30, and fixed cutters 34 provided at a plurality of parts on the cylinder body 4 side to correspond to each cutter claw 31. Be prepared. In such a wire cutting device 26, the movement of the swinging drive device 33 into and out is transmitted to all the cutter claws 31 via the respective plate links 30 and rod links 32, and these cutter claws 31 are simultaneously moved in each vertical direction. It oscillates synchronously around the axis 29, and the arrow Z in Fig. 3
As shown in , the fixed cutter 34 corresponding to each cutter claw 31 is oscillated toward and away from the fixed cutter 34 . The imaginary line in FIG. 3 shows the state when the swing drive device 33 is pushed out. On the other hand, the accumulation mandrel 23 consists of four rods 3 erected in parallel around the pillar 35.
The upper end of 6 is bent inward, and the fitting tool 3 is attached to the tip of the upper end.
7 are fixed to each other, and a pedestal 38 of an integrated wire rod is provided at the lower end thereof. Such an accumulation mandrel 2
3 are alternately transferred between the cart 18 and the support frame base plate 22A through the lifting and lowering operation of the lifting support device 24. Then, when the accumulating mandrel 23 is lifted from the cart 18 by the elevating support device 24, the fitting tool 37 is inserted into the centering cone 2.
It fits into a fitting hole 39 formed at the center of the bottom of the holder, and the two are concentrically connected. In this case, the centering cone 2 is supported by the collecting mandrel 23. In other cases, the centering cone 2 is supported by the swinging protrusion/retraction claw 28B of the lower dividing device 25B.

In the above, when the coiled wire C is supplied to the collecting mandrel 23, the collecting mandrel 23 is connected to the centering cone 2 as shown in FIGS.
By the operation of A, 12B, the wire receiving member 11A,
11B is set at a position above and close to the accumulating mandrel 23, as shown by the imaginary line a in FIG. )
shall be. The coiled wire C after cooling is connected to its supply path L.
The wire falls from the end of the wire rod, passes through the falling path l, is guided by the centering cone 2, and is sequentially accumulated on the wire receiving members 11A and 11B. At this time, the wire receiving members 11A and 11B are gradually lowered according to the amount of the coiled wire C supplied, and at the time when the coiled wire C for 1 bit is supplied, they are slightly lower than the collecting mandrel holder 38. It descends to the point [FIG. 2, imaginary diagram b] and transfers it to the mandrel 23. The front end or rear end of the coiled wire C is cut off from the product as a crop. The crop is separated by combining the operation of the upper dividing device 25A or the lower dividing device 25B and the operation of the wire cutting device 26. That is, the swing drive device 33 is extended while the wire C is prevented from falling by the upper dividing device 25A and/or the lower dividing device 25B. By this operation, plate link 3
0. A plurality of cutter claws 31 connected to each other by a rod link 32 each swing synchronously by a predetermined angle around the vertical axis 29, and work together with a fixed cutter 34 corresponding to each cutter claw 31. At that time, if the coiled wire C in the falling path l falls on one of the claws 31
The cutter is cut by the cooperation of the fixed cutter 34 and the fixed cutter 34. After cutting, the swing drive device 33 is contracted to return each cutter claw 31 to its original position, leaving it in a non-operating state. The same applies to half cuts.

As described above, according to the present invention, a coiled wire can be cut effectively.
