Since the planetary roller 9 is backed up by a backup wheel 11, a rolling treatment can be performed while keeping remarkably large rigidity on each part of a device. Also, since three planetary rollers 9 or more, are mounted, satisfactory stability is attained. The rolling interval (a time required from the completion of rolling of an adjacent roller to a start of rolling) of each roller, is properly determined according to the number of rollers, the width of a product, etc. Consequently, when performing this rolling and traditional rolling, an effect having a cross character, is attained, a material selection is not necessary, and an effect having a two-direction property which is close to an isotropic property, is attained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planetary cloth rolling method and a rolling apparatus for rolling a long metal material in a width direction (a direction perpendicular to the material traveling direction) at a high speed. .

[0002]

2. Description of the Related Art Conventionally, a technique for rolling a long metal material in the width direction has been previously proposed by the present inventor (for example, Japanese Patent Publication No. 59-46683).

Further, a technique of rolling a long metal material in a traveling direction of the material between the planet rollers or between the planet rollers and the anvil has been known.

[0004]

The above-mentioned technique for rolling a long metal material in its width direction has produced great results and has been industrially used. However, this technique uses a rolling roller in terms of metal material. Since it is a method of reciprocating rolling in the width direction, it is difficult to roll at a high speed, which has been a problem for mass production. In addition, when rolling a long metal material in a direction (width direction) perpendicular to its traveling direction by rolling it back and forth, the material receives an alternating rolling force and the elongation in the width direction also differs. However, there is a problem that the edges of the rolled product are apt to be unevenly distributed (easily wavy). Further, there is a problem that the central portion of the material is hardened and the deformation resistance becomes larger than that of the edge portion.

The technique of using the planetary rollers to roll the long metal material in the longitudinal direction is not only impossible in the widthwise rolling of the metal material, but also between the outer side of the planetary roller and the anvil. Since the metal material is charged into the structure, there is a problem in the erection rigidity of the planetary roller, and it was recognized that widthwise rolling is extremely difficult.

[0006]

SUMMARY OF THE INVENTION However, the present invention has solved the above-mentioned conventional problems by charging a long rolling material between a sun roller and a planetary roller and rolling the material successively.

That is, according to the present invention, in the method for rolling a long metal material in the width direction, the long metal material is rolled between the sun roller and the planetary roller in order to roll the long metal material between the sun roller and the planetary roller. And a planetary cloth rolling method characterized by charging from the direction of the central axis of the planetary roller,
The long metal material is characterized by being loaded while applying tension and sequentially rolled, and the long metal material is characterized by being advanced to a predetermined length when not rolled and charged. It is a thing. Further, the invention of the device is provided with an anvil on a part of the outer wall of the sun roller fixedly installed on a stand, and along with the outer peripheral wall of the sun roller, the planetary roller is abutted and installed, and installed so as to move, A backup wheel is fitted on the outer side of the planetary roller, and a material charging means for charging a long metal material from the direction of the central axis of the backup wheel is attached between the anvil and the planetary roller. It is a cross rolling device, to a part of the outer wall of the sun roller,
A groove parallel to the central axis of the sun roller is provided, and the anvil is fitted into the groove so as to be able to move in and out, and a wedge piece for adjusting the moving amount of the anvil is interposed between the groove bottom and the inner wall of the anvil. The material charging means is a pinch roller made of a long metal material, which is installed before and after the rolling device. Next, another invention is one in which an anvil is installed on the upper side wall or the lower side wall of the sun roller, or both, and the planetary rollers are equidistant to the inner circumference of the backup wheel, or a set of two to three rollers. Each set is installed at equal intervals, and a plurality of planetary cross rolling devices are arranged in tandem.

In the above, there are cases where the upper surface of the anvil and the surface of the planetary roller are kept parallel and where there is an angle.

In the former case, a long metal material must be simultaneously charged for the length of the planetary roller, but the amount of charging is large, so the rolling speed is increased and the elongation in the longitudinal direction is almost eliminated. There is a characteristic that makes it disappear. In the latter case, there is a characteristic that a long metal material can be charged to a predetermined length (for example, one tenths of the length of the planetary roller) and a plurality of the same portions can be rolled.

Therefore, it is difficult to judge the superiority or inferiority between the above two rollings, and the selection is made according to various conditions such as the material of the long metal material, the number of rolling mills connected in tandem, and the amount of reduction in one mill pass. .

The number of the planetary rollers in the above is preferably three or more, but if the number is large, the width of the rolled product is restricted by itself, so it is appropriately determined according to the product width to be obtained. In the above, it is not preferable to use two planetary rollers because the installation state of the planetary rollers becomes unstable. Further, if the width of the rolled product becomes wider than the distance between the planetary rollers, at least one roller is in a state of being constantly rolled, so that the long metal material cannot be charged. Therefore, the number of planet rollers is limited in relation to the width of the rolled product.

In the rolling method according to the present invention, a long metal material is charged between the sun roller and the planet roller,
Since the planetary rollers are backed up by the backup wheel (housing), the rigidity can be kept extremely high.

Further, since the elongated metal material is tensioned in its advancing direction and a feeding means is added, the metal material is advanced to a predetermined amount immediately after passing through the planetary roller, and then advanced to the same amount. Can be made.

The gap between the surface of the anvil and the outer wall of the planetary roller can be adjusted by applying a known method such as moving a wedge piece with a screw.

The rolling apparatus according to the present invention can be used by rolling only one unit, or a plurality of units can be connected in tandem. However, the number of tandem connections, the number of planetary rollers, etc. can be determined by the material of the metal material and the product. Depending on the width and the purpose of rolling, etc., it is appropriately selected. The long metal material that can be rolled according to the present invention may have a circular, rectangular, strip-shaped or other various cross-sectional shapes, but the product is substantially strip-shaped.

Further, since the long metal material is rolled in the width direction, the long product can be rolled remarkably wide in one device pass as in the case of the conventional rolling with the reciprocating roller, and cracks are generated at the edge of the product. High quality products can be continuously produced. Since the rolling process can be performed at a higher speed, the productivity can be dramatically increased.

[0017]

According to the present invention, rolling is performed between the sun roller and the planetary roller, and the planetary roller is backed up by the backup wheel, so that the rolling treatment can be performed while maintaining a remarkably large rigidity in each part of the apparatus.

Further, since three or more planetary rollers are installed, the stability is very good, and the rolling interval of each roller (the time from the end of rolling of adjacent rollers to the start of rolling) is the number of rollers, product width, etc. Will be determined as appropriate.

[0019]

Example 1 On the outer periphery of a solar roller having an outer diameter of 400 mm,
Diameter 120 mm, length 200 mm that can roll the outer wall
8 planet rollers are installed at equal intervals, and a backup wheel is fitted on the outer side thereof. The backup wheel was rotated 500 times per minute, and a stainless steel strip having a thickness of 1 mm and a width of 40 mm was inserted between the anvil provided on the sun roller and the planetary roller, and when passing through one rolling device. , The stainless steel strip has a thickness of 0.5
mm, width 80 mm, the speed was 3 m / min (the product stretched almost 5% in the length direction).

However, since the rolling process is continuously performed for a very short time, the plastic deformation of the stainless steel can be facilitated and the metal material can be improved. Furthermore, since it is unidirectional rolling, there is no risk of waviness on both edges of the product, and it is possible to mass-produce excellent products.

[0021]

[Embodiment 2] An embodiment of the apparatus of the present invention will be described with reference to FIGS.

The sun roller 2 on the roller base 1 (stand)
The mounting shaft 3 of is fixed horizontally. A groove 4 parallel to the central axis is provided on the upper outer wall of the sun roller 2, a wedge piece 5 and an anvil 6 are sequentially stacked in the groove 4, and the tip of the adjusting screw 7 is attached to the outer end portion of the wedge piece 5. Mount freely. The adjusting screw 7
Is rotatably connected to the outer end portion of the wedge piece 5 and screwed to a support plate 8 fixed to the sun roller 2. On the outer peripheral wall of the sun roller 2, parallel to the mounting shaft 3,
A plurality of planet rollers 9 and 9 are rotatably mounted on the racks 10 and 10. A backup wheel 11 is fitted on the outer side of the planet rollers 9 and 9, and between the backup wheel 11 and the pulley 12 of the motor. The belt 13 is worn.

In the above embodiment, when the motor (not shown) is started and the tip of the rolled material 14 (for example, stainless steel strip) is loaded on the anvil 6, the belt 13 is indicated by an arrow 15 in FIG. If it moves in the direction of, the backup wheel 11 rotates as shown by the arrow 16, so that the planet rollers 9, 9 revolve in the direction of the arrow 16 while rotating on their own axes. Then, the rolled material 14 is rolled by the anvil 6 and the planetary rollers 9 from the width W ₀ to W ₁ as shown in FIG. The symbols in FIG. 6A are as follows.

A = advanced amount b = reverse amount c = W ₀ = material width h ₁ = rolled thickness h ₀ = material thickness l ₁ = working interval l ₂ = distance between working point and neutral point l ₃ = Distance between center line and center point

That is, the product width W ₁ in one device pass is
W ₁ = a + b + c (W ₀ ).

Although the embodiments of FIGS. 1, 2, and 3 are installed above the sun roll with the anvil facing upward, the anvil can be positioned downward as shown in FIG.

Further, as shown in FIG. 4, two anvils facing upward and downward can be provided for one solar roll (double the efficiency). In this case, if the planetary rollers are even (FIG. 4 (a)), simultaneous rolling is performed at two places, and if odd (FIG. 4 (b)), simultaneous rolling is not performed (because the anvil is centrally symmetrical).

In the above, the material 14 is sent by two sets of pinch rolls 17 and 18 as shown in FIG.
Tension is applied. Therefore, when the material is not rolled (when the material and the planetary roller do not come into contact with each other), the pinch rolls 17 and 18 are rotated as indicated by arrows 19 and 20, and the material 14 is indicated by the arrow 2.
It can be moved in the direction of 1.

The wedge piece 6 is moved in the direction of the arrow 22 or 23 by rotating the adjusting screw 7, and the anvil 6 is moved.
Is moved up and down as indicated by arrow 24 or 25. Therefore, the gap between the upper surface of the anvil 6 and the processed surface of the planetary roller 9 is adjusted, the reduction amount is determined, and the product thickness is determined.

Reference numeral 26 in the figure denotes a sun roller fixing screw.

The rolling mill A of the present invention can be used alone, but normally, as shown in FIG. 7, a plurality of rolling mills A ₁ , A ₂ ,
A ₃ and A ₄ are used in tandem connection. In this case, the final product can be made with one device pass. For example, a material having a thickness of 1.0 mm and a width of 10 mm is 0.2 mm in thickness and 5 in width.
It can be processed to 0 mm.

The number of rolling devices connected in tandem in the above is appropriately determined according to the purpose of use.

When the number of planetary rollers is increased, the distance between the rollers becomes narrower and there are restrictions on their own. However, as shown in FIG. 8, the two rolling rollers B of one group B are brought close to each other, and each group B ₁ , B ₂ ,
If the distance between B ₃ and B ₄ is made as wide as possible, the restriction due to the width of the rolled product can be greatly reduced.

[0034]

According to the present invention, since the rolled material is continuously rolled in the same width direction, it is possible to increase only the width without extending the length. Therefore, there is an effect that it can be rolled at a high speed.

Since the rolling of the present invention and the conventional rolling have the effect of crossing the rolling direction of the metal material, it is possible to remove the material from the metal plate during pressing or bending. There is no need for selection, and there is an effect of having bidirectionality close to isotropic.
