Abstract

PURPOSE:To reduce the size over the entire part of a rolling mill and to perform easily changing of a size, etc. by disposing plural pairs of rolling rolls on parallel axial lines and making their directions the same. CONSTITUTION:Wire-shaped bodies 1, 1' to be rolled are passaged respectively through the rolling gap (g) on both sides of rolling rolls 12, 12' and the rolling gap (g) on both sides of rolling rolls 14, 14' and are thus rolled. The body 1 in this case is rolled down diagonally leftward between the 1st pair of the rolls 12 and 12' and is rolled down diagonally rightward at a right angle to the previous rolling down direction between the 2nd pair of the rolls 14 and 14'. On the other hand, the body 1' is rolled down diagonally rightward between the rolls 12 and 12' and is rolled down diagonally leftward between the rolls 14 and 14'. The wire- shaped bodies are thus rolled down in the rolling down direction changed by each 90 deg., whereby the sectional area is reduced and the wire bodies having a desired section are obtd.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention consists of 1. This article deals with the linear body pressure 9#, tat, which produces a linear body sound of a predetermined size based on the diverticulate body pressure.

Conventionally, drawing is performed to manufacture linear bodies.

However, since drawing process G requires the master of the die and the work of threading the wire, a labor meeting is required. 17) As another method, extrusion processing is used, but in this method, the dimensions are stacked on a long bow'+iL'L, and the quality of Table 4 is insufficient and the die and die The replacement work requires a total of 17 pieces of labor. For this reason, rolling has not been used recently. but,
In order to roll a linear body, the VC must be rolled from the angle of the ridges. It is a poor quality, and there are often disadvantages when setting the low / l / to improve the size of the text. In addition, it is arranged in the same axial direction.
L A linear body t90 that should be rolled into a plurality of pairs of 7 rolls.
``Attempts have also been made to twist the wires around each other and roll them through, but this 1° twisting often resulted in defects in the 43 material due to the linear body twisting f'L.

The object of the present invention is to reduce the overall size of the apparatus Mt by arranging seven pairs of rolling rolls on parallel axes, and to easily perform dimensional changes, etc., to roll a linear body. We are here to provide you with all the benefits you need.

Describing the embodiments of the present invention in detail with reference to the drawings, the first embodiment is described in detail with reference to the drawings.
The figure shows a linear body rolling mill 10 according to the present invention, and this rolling mill has a plurality of pairs of rolling rolls 12, 12' and 14, 14' rolled in tandem on mutually parallel axes. 〃
・It consists of In the drawing, only t 2 pairs are volley U ruru 7
We have a lot of cultural meetings at the center of J'X. As shown in FIG. 2, the pair of valley pressure rolls are inclined at an angle θ with respect to their axis Surface 18 and sorL (
” fl. In the illustrated embodiment, the male sloped shoulder surface 16
is the inclined surface of the V-groove 17 in cross section, while the male inclined shoulder surface 1
Reference numeral 8 denotes a slope around 1 of the flange 19 having a V-shaped cross section.

In some of these pairs of rolling rolls, the upper roll is R.
The lower roll has a male inclined shoulder surface 18 on the inclined M surface 16' of the mold.
However, in the other pair of rolling rolls, the upper roll has a J & type inclined M surface 18, and the upper roll has a male type inclined shoulder surface 16. In the illustrated embodiment, rolling roll 1
2 and 14' have a female mold 11'iI inclined surface 16, and the rolling rolls 12' and 14 have a male mold 1 and a diagonal h1 surface 18, which are alternately applied in opposite directions.

As shown in FIGS. 1 and 2, the rolled hemline linear bodies 1 and 1' are formed by a compression gap V on both sides of the rolling rolls 12 and 12' and a rolling gap V on both sides of the rolling rolls 14 and 14'. Each length 2'L is passed through the gap 2 and subjected to one pressure treatment. In this case, the linear body 1 is
As shown in FIG. 3, the tenth pair of rolling rolls 12,1
Between 2' and 2', the lowering type fL is oriented diagonally to the left.

Between the next second pair of rolling rolls 14 and 14', the previous rolling direction and the right side of the first roll are rolled by -1.

4--The line of force 1' is connected to the first pair of rolling rolls 12, 12
At ', the roll is rolled down diagonally to the right -cE tt , and rolled down by the pair of rolling rolls 14 and 14' of 42 to the left side.

In this way, the linear body is pressed first by changing the pressure direction by 90 degrees. As the cross-sectional area decreases, the cross-sectional shape of the linear bodies 1 and 1' becomes rounder in the direction in which the desired linear bodies are squeezed. layer plane 16,
18 has a shallow arc shape n916a, 18a2 type J.

In the above embodiment, each pair of rolling rolls has a V-shaped or V-shaped 7
Although two rolling gaps WAk are formed by the lunge, one half of the rolling gap WAk may be omitted to form one rolling gap WAk, or only one of the two rolling gaps may be used in its entirety. It was,
In the above embodiment, the direction of the oblique/if plane was alternately reversed around 1, but it is also possible to rearrange two pairs of rolling rolls 12°12' in succession, and then arrange all two pairs of rolling rolls 14°14' in succession. Well, the combination can be left up to you.

According to the present invention, as described above, the number of pairs of rolling rolls are arranged on the same axis and are oriented in the same direction, so that the overall size of the apparatus can be reduced. Since there is no need to twist and roll the linear body during rolling, it is not possible to obtain a product that looks like a stealth product. Since it only requires a single step, it is possible to fully automate the operation of the machine without requiring any labor.
