。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wire rod rolling method for obtaining a wire rod of a predetermined wire diameter by rolling a wire rod instead of drawing the wire using a wire drawing machine.

く。(Prior art) A conventional wire drawing machine consists of multiple dies arranged in tandem. A hand Yapustan was placed between the matching dice. For this reason, the wire drawing machine itself requires a large space, which has the drawback of increasing the work space. Furthermore, when processing with a wire drawing machine, work hardening is large due to the flow of the wire.

点があったそこで伸線機に代えて圧延機を使用して加工
硬化を小さくすることが考えられる。しかし。In particular, when the wire is made of an alloy, it requires several intermediate annealing steps, resulting in low workability.Also, it is necessary to constantly manage the dies. There was a drawback that a large amount of labor was required due to the need for tacking, so it is considered to use a rolling mill instead of a wire drawing machine to reduce work hardening. but.

延機では細径の線材を得ることが難しかった。A rolling mill can be safely equipped with several roll stands, and each stand is usually equipped with a gear transmission, so equipment costs can be reduced.
It was difficult to obtain small-diameter wire rods using ordinary water rolling mills or direct rolling mills due to the high dimensional accuracy.

定線径の線材を得ることを特徴としている。(Structure of the Invention) The wire rod rolling method of the present invention involves forming annular grooves having hole shapes of different sizes in adjacent rolls of rolls arranged in multiple stages by shifting them in the axial direction. , forming a first rolling die between opposing annular grooves of one adjacent roll;
A diameter smaller than the first rolling N1 is formed between the matching annular grooves of the next adjacent roll, which is composed of the second roll of this one adjacent roll and the third roll [1] of the next adjacent roll. A second rolling mold having a dimension of The wire rod to be rolled is sequentially passed through the first rolling die between the annular grooves of the rolls, and the wire rod drawn out of the first rolling die is twisted approximately 90' and transferred to the second rolling die for rolling, and the above operation is performed. It is characterized by repeatedly obtaining a wire rod of a predetermined wire diameter.

。By doing this, there is no need for intermediate annealing because the work hardening is not as great as in the case of wire drawing with a wire drawing machine. Since the rolling process is carried out between 1 and 2, the transmission device is simple and the equipment cost is low, and the wire rod can be rolled at a large downstream rate, making it possible to obtain a wire rod with a small diameter.
