た後に多くの場合、高温状態において、熱間圧延ロール
を用ひて、平板状にまで、圧延される。In recent years, so-called new materials called difficult-to-add materials have appeared. In many cases, the new raw material is rolled into a flat plate by using a hot rolling roll in a high temperature state after completing the electric melting of the raw material.

である。Among the new materials mentioned above, titanium or titanium alloy, which is said to be difficult to process, is a fine wire material manufacturing process, and it is a point that the substance is ridden by the manufacturer. As a result, the degree to which the molding tool is worn is large.
【0006】従って成形器具との相対摩擦速度を極めて
小さくすることが必要であるとされている。Therefore, it is necessary to make the relative friction velocity with the molding tool extremely small.

が、前記特性上高速生産は至難とされていた。On the other hand, industrially, the speed is one digit higher (for example, 2
Although it is necessary to manufacture a thin wire at a production rate of 00 m / min), high-speed production has been extremely difficult due to the above characteristics.

−26763号)。2. Description of the Related Art Conventionally, a thin metal plate 1 is placed on a rolling roll to form a large number of V-grooves 3 (FIG. 6), which is torn from the bottom of the V-grooves to form a metal wire rod 7, which is formed by forming rolls 9 and 9. An apparatus for manufacturing metal wires is known (Japanese Patent Publication 1)
-26763).

れば、一回の圧延ロールによるV溝形成では過大な圧加
力を必要とするのみならず、残留厚さ部分の引裂抗力が
大きい為に、強大な引張力を必要とする問題点があっ
た。According to the conventional manufacturing apparatus described above, not only an excessive pressurizing force is required for forming the V groove by one rolling roll, but also the tear resistance of the residual thickness portion is large. However, there is a problem that requires a large tensile force.

度に製造される金属線材の数が少なくなるなどの問題点
もあった。As described above, the reason why the excessive pressing force is required is that the pressing area (S surface in FIG. 6A) is large in order to form the cross section as shown in FIG. 6A. Because of that. Therefore, the convex portion of the rolling roll is significantly worn out, and the tear cross section cannot be made thin, so that a large tearing force is required. In addition, the need for excessive pressurizing force causes a limitation in the thin metal plate that can be processed at one time, and naturally there is a problem that the number of metal wire rods manufactured at one time decreases. .

により粗面を補正しなければならない問題点があった。Further, in the above-mentioned known technique, since the erection axes of the rolling roll for forming the V groove and the rolling roll for forming the metal wire are parallel to each other, the forming roll is formed on the front and back sides of the thin metal plate. Since the roll comes into contact and the torn surface cannot be molded, the torn surface (XY cross section) of the metal wire remains as a rough surface, so the rough surface must be corrected by cutter cutting or other means after tensile cutting. There was a problem that had to be addressed.
【0013】前記強力は引張力を必要とするのみなら

点があった。Since the above-mentioned strength requires not only a tensile force but also a correction means such as cutting, there are problems that the manufacturing efficiency of the metal wire is lowered and the manufacturing cost is increased.

法である。That is, in the invention of the wire rod, in a cross section perpendicular to the center line of the elongated material, there are parallel sides of a predetermined width at the upper and lower sides, and inclined planes made up of a plurality of broken lines are provided on the left and right sides of the parallel side and the cross section is vertically symmetrical. The metal wire rod is characterized in that Further, the invention of the method is such that a thin plate material is pressure-molded from above and below by a rolling roll to form a V groove symmetrically in the vertical direction, and adjacent wire materials which are separated by the groove portion of the thin plate material are alternately arranged on one surface of a separation plate having an acute angle or A method for manufacturing a metal wire rod, which is characterized in that it is alternately drawn to the other surface, wherein a thin plate material is pressure-molded from above and below by a rolling roll to form V grooves symmetrically in the vertical direction, and the front of the V groove forming portion is formed. In the method of manufacturing a metal wire rod which is alternately separated into upper and lower parts by interposing a separating plate having an acute angle, the V groove is formed by a plurality of freely rotating rolling rolls, and the V groove angle becomes smaller as the depth becomes deeper. This is a method for manufacturing a metal wire rod.

A plurality of sets of rolling rolls are installed in parallel. The angle of the V-shaped annular ridge of the first rolling roll is maximized, and the angle of the V-shaped annular ridge of the subsequent rolling roll is gradually decreased.

The rolling rolls of No. 1 and No. 2 gradually reduce it to 50 °.
【0022】但し角度の低減量は前記に制限されるもの

属線材ができる。EXAMPLE A titanium thin plate 1 having a thickness of 4 mm is rolled on first rolling rolls 2 and 2 to form V grooves 3 and 3 having a pitch of 5.6 mm and an angle of 90 °. Next, the second rolling rolls 4 and 4 are formed into V grooves 3a and 3a having an angle of 70 °, and the third rolling rolls 5 and 5 are further formed into V grooves 3b and 3b having an angle of 50 °.
To mold. Since the second and third rolling rolls 4 and 5 are installed so as to be freely rotatable, the pressing force at the time of roll forming is significantly reduced. Therefore, a large number of metal wire rods can be produced by processing once.

The titanium wire rods 7 and 7 wound up as described above are successively welded one after another, and then molded by a known cassette roller and drawn to a predetermined diameter to form a titanium wire having a long desired diameter.

However, the number of rolling rolls and the angle thereof are not limited to those described above, and the number of rolling rolls and the V-groove forming angle are appropriately selected depending on the material of the material to be rolled.

の発生を未然に防止することができる。Further, as shown in FIG. 3- (b), the roll groove formed by a roll (cassette roller or rolling roll) used for rolling forming when the separated metal wire 7 is further guided to the thin wire process is as shown in FIG.
Since the flat surfaces 3c and 3c are provided between the adjacent V-grooves 3 and 3, a flow gap 14 of the material is generated between the ridges of the forming roll 13 at the time of pressure forming of the wire rod, and fins are generated by the roll forming. Can be prevented in advance.

ことができる。Further, since the V groove is sequentially formed by a plurality of rolling rolls, the reaction force at the time of forming by one set of rolling rolls becomes relatively small, the rolling speed is improved, and the number of wire rods that can be formed simultaneously is increased. The binding rolling efficiency can be improved.

くすることができる。Further, the final shape of the V groove has a more acute angle (for example, 5
0 °) makes the stress concentration at the time of tearing rational, and a large tearing force can be obtained with a relatively small force. In combination with the effect of the separating plate, a large tearing force can be obtained with a relatively small force. The same effect as above can be obtained, and the forming speed can be increased and the width of the metal thin plate that can be processed at one time can be increased.

諸効果がある。According to the wire of the present invention, since fins are not generated at the time of rolling and forming, the secondary processing for cutting off the fins is unnecessary, and as a result, the processing cost can be reduced. According to the method and apparatus of the present invention, the V groove is sequentially processed, so that the pressing force when passing through one set of rolling rolls is relatively small and the object can be sufficiently achieved.
Therefore, there is an effect that it is possible to perform roll forming from a wider metal thin plate at a higher speed. In addition, since a separating plate is used, the tearing force can be small, which saves power and the winding tightening force of the take-up reel.Because the tightening force at the time of winding is small, there is no risk of being caught too hard. There are various effects such as no.

The frictional relative speed is small, and the friction of the annular projection is significantly reduced.
