切断面にダレが生じ易い、ま曳、線材の加工硬化指数の
違いによっても最適なりリアランスが異なる。In the header, the clearance between the cutter and the shear die has a significant effect on the cut surface of the wire. In other words, if the clearance is small, seizure will occur between the cut nine wire rod and the shear die, and if it is large, the cut surface of the wire will likely sag, sagging, or due to differences in the work hardening index of the wire. The optimal reality is different.

However, this method requires the skill of the operator, and it is troublesome to adjust the gap accurately.As a result, the cutting surface and cutting length tend to have puff marks, and the adjustment time is long. Driving [Unmanned driving is extremely difficult.

The wire rod fed to the row My5.5 of the wire rod feeder 6 during operation of the header is inserted into the wire rod feed hole 3 of the cutter die 1 through the feed port 4Tt, and is inserted into the wire rod feed hole 3 of the cutter die 1 through the M material feed hole 5 and the cutter die. The cutter holder a is moved to a position where the through holes 9 of 8 meet, and at 9 o'clock the row '95° 5 of the wire rod supply device W6 is driven to rotate until the tip of the wire comes into contact with the stopper member 24, and then the cutter holder is moved together with the cutter holder duff. 8 is moved in the direction of the arrow to cut the wire to the set length. Next, when the cutter 8 reaches the end of its service life and needs to be replaced, the cutter holder 7 is moved in the position where the cutter 8 faces the V-go die 1. As it comes to rest, the rod i4m of the clamping cylinder 14 contracts, and the presser claw 12 is rotated in the opposite direction of arrow B by the elastic force of the spring 15, and the clamping by the clamping device 1f11 is released.After this, a cutter replacement device (not shown) is installed. Wt&: The used cutter 8 is removed from the holder portion 7a, and a new cutter 8 is inserted into the holder portion a. After insertion, air from the compressor is supplied to the air cylinder 17, and the guide member 19 moves the cutter 8 to the cutter 8. 8 guides will be conducted. Thereafter, the DC flow controller 21 is rotated forward, for example, and the movable member 22 is moved in the direction of arrow C, that is, in the direction of the cutter 8. When the stopper member 24 comes into contact with the cutter 8, the cutter 8 is further moved against the leaf spring 10. It is moved in the direction of arrow C while being guided by the guide member 19.

The pressure sensor 23 detects this, the DC motor 21 is stopped, and the f-flow motor 21 is rotated in the opposite direction as indicated by the counter arrow C.
direction, and the stopper member 24 is moved to the above-mentioned stop position [
It was set in advance as a starting point and moved by a set dimension corresponding to the clearance of the telekinetic vine 8, and at 9 o'clock, the l-flow motor 21 was automatically stopped, and immediately, pressure oil was sent to the clamping V cylinder 14, and the rod 14& was expanded. The presser claw 12 rotates in the direction of arrow B, and the cutter 8 is fixed to the holder portion 7a of the cutter holder 7. Thereafter, the air cylinder 17 contracts, and the guide member 19 is separated from the cutter 8. Since the cutter 8 is moved in the opposite direction of arrow C following the stopper member 24 by the 1° angular force of the leaf spring 10, when the clamping device 11 is activated, the cutting surface 1a of the shear die 1 and the cutter 8 are moved. After the clamping device 11 is activated, the DC 1,1 motor 21 is further rotated in the reverse direction, and the tip of the stopper member 24 is moved from the cutting in'i1m of the V-E die 1. They are stopped after being separated by a distance corresponding to the cutting length of the wire.

も好適なものとなる。According to the above configuration, the dimension from when the movement of the stopper member 24 is restricted to 2 degrees until the stopper member 24 automatically stops can be set in advance according to the material and diameter of the material. There is no need for the operator to adjust these clearances manually even when replacing the V-E die 1 and cutter 8 or when the wire material is different, and the header can be adjusted automatically and accurately. It is also suitable for autonomous driving.

い。In addition, in the above configuration, the wire rod cutting length 11i'T is set using the stopper member 24 during normal operation, but a dedicated stopper for adding the wire rod cutting length 7 is provided on the frame 2 and moves during normal operation. It is also possible to adopt a configuration in which the fff20 is past a position not facing the 1V yard die 1.
