本発明は、線状体圧延機の改良に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in a linear body rolling mill.
（従来技術）
一般に、線状体を細径化する場合に引抜き加

ダイス交換と線通し作業とを伴なうので作業性が

た。(Prior Art) Generally, when reducing the diameter of a linear body, there are drawing processes, pressing processes, and rolling processes. Drawing involves exchanging dies and threading the wire, resulting in poor workability and high work hardening, which has the disadvantage of requiring many intermediate annealing cycles for materials that are difficult to process, resulting in low productivity. In addition, press processing has problems in terms of elongation, dimensional accuracy, and surface quality, and cannot be applied to materials that are particularly difficult to process. Furthermore, a rolling mill consisting of three-sided rolls has been proposed to roll the material from various angles in order to reduce the diameter of the material during rolling processing.
Compared to a wire drawing machine, this device is more complicated and expensive, and it is troublesome to change the rolls.

性が低くなる欠点があつた。 On the other hand, the present applicant previously proposed a pair of male and female rolling rolls that engage with each other in order to roll a linear body, which is a rolling material, from various angles, and the female rolling roll has a female type inclined shoulder surface. The male rolling roll has a male inclined shoulder surface facing the female inclined shoulder surface through a rolling gap, and the linear body which is the rolling material is rolled with a rolling gap between one inclined side of these rolling rolls. proposed a linear rolling mill in which rolling is carried out on opposite sides of the wire (see Japanese Patent Application No. 57-19603 and No. 59-42881).
Although this rolling mill rolls the material from various angles, all the rolling rolls are arranged on parallel axes and are oriented in the same direction, making the overall equipment smaller and cheaper. There is an advantage that the size of the product can be changed simply by adjusting the rolling gap between each pair. However, the proposed rolling mill had the drawback that the width of the linear material to be rolled increased due to the inclined shoulder surfaces of the rolling rolls, resulting in a lower area reduction rate and lower productivity.

いる。(Structure of the Invention) The linear object rolling mill of the present invention comprises a pair of rolling rolls that engage with each other, and the linear object to be rolled is rolled through a rolling gap between the rolling rolls. , a pair of rolling rolls each have carrier bars facing each other forming a rolling gap, and the carrier bars are asymmetrical with respect to a perpendicular bisector b of a line a connecting the mutually engaging carrier edges. but,
The rolling gap has a shape that is point symmetrical with respect to the intersection point M between the perpendicular bisector b and the line a connecting the carrier edges, and the line a connecting the carrier edges is inclined with respect to the axis x of the rolling rolls.

むことが解る。 In this structure, as mentioned above, the line a connecting the carrier edges is inclined with respect to the axis of the rolling roll, so the material is inclined with respect to the axis x of the rolling roll after rolling. By arranging a plurality of pairs so that the lines connecting the carrier edges are in opposite directions, the rolled material can be rolled from various angles. In particular, since this rolling gap is closed, unlike the linear body rolling mill with inclined shoulders previously proposed by the applicant, no widening of the material occurs. In particular, the carrier bars are asymmetrical with respect to the perpendicular bisector b of the line a connecting the mutually engaging carrier edges, but the rolling gap formed by the joining of the opposing carrier bars is the perpendicular bisector b. Since it has a shape that is point symmetrical with respect to the intersection point M between the line a connecting the carrier edge and the carrier edge, the widening of the material is suppressed most efficiently due to the asymmetry of the carrier shape, so the area reduction rate is as large as possible. Therefore, productivity can be improved. In addition, since the rolled material is erected by increasing the angle of the line of symmetry of the rolling gap with respect to the roll axis and making the inclination as small as possible, the torsion angle can be small when the material is erected in the next process. I understand.

成形加工されるので製作が容易となる。The rolling gap 16 shown in FIGS. 1 to 3 has an elliptical shape, a parallelogram shape, and other similar but different shapes. That is, a line a connecting the carrier edges 14a, 14b, 14'a, 14'b of the carrier 14 is inclined with respect to the roll axis x. Therefore, the carrier edges 14a of the rolling rolls 12, 12'
The diameter Da on the 14'a side is smaller than the diameter Db on the opposite side. Note that it is desirable that the difference between these diameters Da and Db be as small as possible considering the strength of the roll, but if this is done, the angle θ of the central axis c of the rolled material with respect to the roll axis x will be small. Caliba 14, as it becomes somewhat disadvantageous as it gets older.
It is preferable to consider the shape of 14' so that the angle θ of the central axis c does not become small. For this reason, the first
The calipers 14, 14' shown in FIGS. 3 to 3 have one side deeper than the other with respect to line b. It should be noted that the calipers 14, 14' in FIG. 3 have one side deeper than the other with respect to line b, compared to those in FIG.
Note that the angle θ 3 of the central axis c of the rolling gap 16 in FIGS. 1, 4, and 5 with respect to the roll axis x is 45°; It can be seen that the angles θ 1 and θ 2 relative to x are larger than that and make the material stand up even more. Furthermore, in the embodiments shown in FIGS. 1 and 2, the carrier edges 14a, 1
4b, 14'a, 14'b have cylindrical surfaces, but in the embodiment shown in FIG.
The outside of a, 14b, 14'a, and 14'b has an inclined surface extending from line a and cylindrical surfaces on both sides thereof. In this rolling roll, the caliber bars 14, 14' are formed later, so manufacturing is easy.

た。 In one embodiment of the invention, a 10 mm diameter phosphor bronze wire was rolled with the rolling rolls of FIG. In this rolling roll, line a was 12.5 mm, Da was 118 mm, Db was 136 mm, and the depth of the caliper was 3.1 mm. The area reduction rate of this rolling roll was about 30%. Thereafter, rolling was continued with the area reduction rate of each stand being approximately 30%, and it was possible to roll the product to approximately 2.5 mm without annealing. In addition, the rolling roll shown in Figure 5 was able to roll a phosphor bronze wire with a diameter of 15 mm to a diameter of 1 mm in one annealing process, but if this was done with a conventional wire drawing machine, three annealing steps would be required. It was hot.

る。(Effect of the invention) According to the invention, as described above, the rolled material is
Although the rolling gap is asymmetrical with respect to the perpendicular bisector b of the line a connecting the mutually engaging carrier edges, it is point symmetrical with respect to the intersection M between the perpendicular bisector b and the line a connecting the carrier edges. Since the material is rolled with a rolling roll having a calibar having a shape such that the material has a special shape, it is possible to effectively suppress the spread of the material and roll it with a large area reduction ratio, and the number of annealing operations can be significantly reduced. Productivity is improved, and since the rolling rolls can be arranged horizontally, the equipment can be made smaller and cheaper, which is a practical benefit.
