も生産性が低く、製造原価が高いものとなる。On the other hand, in the case of hard refractory metal materials such as copper, copper alloys and steels, it is difficult to manufacture the modified cross-section strip material by the extrusion method, and even if it can be manufactured, the productivity is low and the manufacturing cost is low. Will be high.

The copper alloy modified cross-section strip material having the following is manufactured by the following method.

り返すことにより異形断面条材を製造する。(1) Flat plate V-shaped die rolling method In this method, a flat plate V-shaped die having V-shaped protrusions is first prepared, and then a flat plate of a material is placed on the protrusions of the V-shaped die. The strip-shaped V-shaped die is placed on the side opposite to the rolling surface of the flat roll of the flat-shaped strip, by placing the strip-shaped strip on the flat-shaped strip and then rolling the flat roll over the flat-roll while pressing the flat roll. The profiled strip is manufactured by biting the projection, then intermittently moving the flat strip in the direction opposite to the tip angle of the projection, and repeating this series of operations.
【００１２】この方法は、素材の平板状条材の幅方向へ
の材料の流れ性が大きく、一工程で成形できるという利
点がある。This method has an advantage that the flowability of the material in the width direction of the flat strip material is large and the material can be formed in one step.
【００１３】しかしこの方法は、圧延成形加工が断続的
であり、その結果加工速度、生産性の顕著なる向上が望
めないという難点がある。However, this method has a drawback in that the rolling and forming process is intermittent, and as a result, the processing speed and productivity cannot be remarkably improved.
【００１４】（２）生産性向上ダイス圧延方法
この方法は、上記（１）の平盤状Ｖ型ダイス圧延方法の

ものである。(2) Die Rolling Method for Improving Productivity This method is intended to improve productivity by continuously rolling the flat plate V-type die rolling method of (1) above.

圧延成形加工する。In this method, first, a planetary rolling machine having a plurality of planetary rolling rolls arranged on the circumference is prepared, and then the rolling surface having a projection on the outer circumference of the planetary rolling machine is curved inward. The curved V-shaped die is arranged, and then the flat plate material made of alloy of the raw material is supplied between the curved V-shaped die and the planetary rolling mill, and then the flat plate material is continuously formed into the modified section strip material. Roll forming process.
【００１６】この方法は、素材の平板状条材を連続的に

生産性の顕著なる向上に効果がある。According to this method, since the flat strip material of the raw material can be continuously roll-formed into the modified cross-section strip material, the processing speed,
It is effective in significantly improving productivity.

置する。(3) Rolling workability improving flat plate V-die rolling method This method was proposed as a method of improving the rolling workability of the above method (2). (Japanese Patent Laid-Open No. 7-32079) According to this method, the planetary rolling rolls of a planetary rolling mill are elastically supported so that their axis can move in the radial direction with respect to the axis of revolution, and their orbits. Is formed into a straight line, and a flat plate-shaped V-shaped die is arranged at a portion facing the trajectory of each planetary rolling roll passing through the straight track portion.

的に異形断面条材へ圧延成形加工する。Next, when the flat strip material as a raw material is fed between the flat plate V-shaped die and the planetary rolling machine arranged in this way, and then the planetary rolling machine is operated, each of them passes through the linear track portion. With a planetary rolling roll, the flat plate material of the material is pressed by the rolling surface of the flat plate V-shaped die, and thereby continuously rolled into a modified cross-section material.
【００２０】なお、ここにおいて圧延成形加工速度は、
（１）式のように定義される。Here, the rolling forming speed is
It is defined as in equation (1).
【００２１】
加工速度＝１回当りの加工長さ×ロール数×単位時間当りの公転数…（１）
従って（１）式からわかるように加工速度を上げるに
は、１回当りの加工長さを長くするか、ロール数を増や
すか、単位時間当りの公転数を大きくする必要がある。Processing speed = processing length per operation × roll number × revolutions per unit time (1) Therefore, as can be seen from the equation (1), in order to increase the processing speed, the processing length per operation Must be lengthened, the number of rolls must be increased, or the number of revolutions per unit time must be increased.
【００２２】[0022]
【発明が解決しようとする課題】しかし、（１）式にお
いて１回当りの加工長さを長くした場合、幅が広い素材
の平板状条材を加工するときにおける１回の加工長さが
減少し、その結果加工速度が遅くなるという難点があ
る。However, when the processing length per operation in formula (1) is increased, the processing length per operation is reduced when processing a flat bar material having a wide width. However, as a result, the processing speed becomes slow.
【００２３】また、（１）式においてロール数を増やす
場合、ロール間距離を平盤状Ｖ型ダイスの加工部長さの
関係で最小ロール間距離以上に空ける必要があり、また
ロール同志の干渉を避けるためにも非干渉距離以上に空
ける必要がある。In addition, when the number of rolls is increased in the formula (1), it is necessary to make the inter-roll distance more than the minimum inter-roll distance due to the relationship of the length of the processing portion of the flat plate V-shaped die, and the interference between the rolls. In order to avoid it, it is necessary to leave more than the non-interference distance.
【００２４】従って、ロール数を増やすには最小ロール

を大きくした装置としなければならない。しかしこのよ
うに公転半径を大きくした圧延装置では装置が大形化
し、その結果保守管理性の悪化や装置価格のアップを招
くという難点がある。Therefore, in order to increase the number of rolls, the constraint between the minimum roll-to-roll distance and the non-interference distance must be removed, so that the device must have a large revolution radius. However, in such a rolling mill having a large revolution radius, the rolling mill has a large size, and as a result, there is a drawback that maintenance and manageability is deteriorated and the cost of the rolling mill is increased.

点がある。Further, in the case of increasing the number of revolutions per unit time in the formula (1), it is necessary to increase the strength and accuracy of the frame material, and to make the weight balance of the rolls uniform and to always maintain that state. Must be
As a result, the apparatus has the drawbacks that the assembly workability is deteriorated, the maintainability is deteriorated, and the apparatus price is increased.

Even if it is, it is possible to remarkably improve the rolling speed and productivity without increasing the space between planetary rolling rolls or reducing the number of planetary rolling rolls. It is to provide a manufacturing method of a strip material.

Since it becomes long, it is necessary to increase the distance between the planetary rolling rolls 6, and accordingly, it is necessary to upsize the planetary rolling machine 5 or reduce the number of the planetary rolling rolls 6. Here, when the size is increased, the price becomes high, and when the number of the planetary rolling rolls 6 is reduced, there is a problem that the reduction of the rolling speed cannot be avoided. On the other hand, in the embodiment of the present invention, since the flat plate-shaped V-shaped dies are installed at two locations on the outer peripheral side of the planetary rolling machine 5, the flat plate-shaped strip 1 of the raw material can be parallel-rolled by two strips each. .
