に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the final finishing step of hot wire rolling (1) - forming a wire rod passed through a rolling mill into a ring shape, and continuously conveying the wire rod to a heat treatment conveyor.
The present invention relates to a method and device for winding wire rods when winding them up and transporting them.

た状態を示す。[Prior art and problems] In gauge wire rod rolling, the wire rod that has passed through the final finishing mill is wound into a ring shape by a winding machine (hereinafter referred to as a "laying head") and transferred to a conveyor for hot treatment. Then, on conveyor 2, in order to obtain the wire rod with the target quality characteristics,
A method is used to transform the material by subjecting it to a certain amount of cooling using a blast of air or a refrigerant such as hot water. FIG. 8 shows a state in which the final finishing mill 2, the rolling head 1, and the heat treatment conveyor 4 are arranged in tandem.

Since the position at which the ring-shaped wire 3 is transferred from the laying head 1 to the conveyor 4 is constant, the amount of linearity at both ends of the ring-shaped wire 3 on the conveyor as shown in FIG. It becomes extremely large compared to . Therefore, there was a problem that the cooling rate was different between both ends and the center, resulting in non-uniformity of the product.

グ状線材の両端部では、鋼材密度が高くなるのである。Such a problem is caused by a laying head and a heat treatment conveyor that are arranged in tandem with a final rolling mill, in which the wire rod formed into a ring shape in the laying head is momentarily held on a ring receiving plate called a tripper. Each ring is supplied to the heat treatment conveyor, but at this time, the ring-shaped wire always passes through the same position and is transferred onto the conveyor, so the rings are spread out non-concentrically on the conveyor. The steel material density is high at both ends of the shaped wire.

In order to prevent the ring-shaped wire rod from falling at the same position on the conveyor, it is necessary to change the passing position of the wire rod and shift the ring laterally after the wire rod is formed into a ring shape and before it is fed onto the conveyor. is necessary.

As shown in FIG. 2, this elliptical cam 7 is located on either side of the exit side of the laying head 1, and the direction of rotation of the cam is to rotate the ring-shaped wire rod in the direction to feed it to the conveyor. In other words, the direction of rotation is opposite depending on the mounting side.

７が回転するように構成する。This oval cam 7 rotates in synchronization with the rotation of the laying head 1, and the cam 7 rotates the wire 3 while the ring-shaped wire 3 is being fed from the receiver to the heat treatment conveyor 4. The falling position is forcibly adjusted to change the position of supplying each ring to the heat treatment conveyor 4. For example, as shown in FIG. 2, when the long sleeve side of the oval cam 7 is vertical, the short shaft side in the horizontal direction does not touch the ring-shaped wire 3, and when the long sleeve side is horizontal, the ring It becomes possible to forcibly change the wire passing position of the shaped wire 3 by I/2 (major axis length - minor axis length). In the laying head 1, when one ring of wire is finally wound, a receiver that momentarily holds and rolls off the wire is constructed so that a cam 7 rotates in synchronization with the fall of the ring-shaped wire from the stand.

ング状線材３の落下位置を変えることができる。(A) In the figure, at the position where the ring-shaped wire rod 3 is rolled down from the laying head 1 to the heat treatment conveyor 4,
A rotating plate 10 is installed parallel to the side surface. As shown in the figure, a plurality of holes 11 are formed at equal intervals on one circumference of the rotating plate 10. This rotating plate 10 rotates in synchronization with the number of rotations of the laying head 1. Therefore, by injecting high-pressure air onto the falling ring-shaped wire 3, the position at which the ring-shaped wire 3 falls onto the heat treatment conveyor 4 can be changed for each ring.
