があった。Recently, this kind of strip c has been used.
For example, in FIG. 1, in the dimensions A and B of the thin portion b with respect to the thick portion a,
High precision is required so that | AB | is 0.1 to 0.05 mm or less, and in order to satisfy these requirements,
A guide for positioning the thick portion a is provided in front of the cutter in the slitter process, and this guide is always manually operated,
Although the work is processed so that the strip material does not shift during cutting, that is, the center shift does not occur, it is troublesome to always perform such a guide operation, and this guide makes it difficult for the rising part side surface of the thick part a and the thin part to be formed. There was a defect that scratches occurred.
Further, the strip c shaped by the rolling rolls e and f is not directly guided to the slitter to cut the both side edges, but the strip c rolled and shaped is once wound and conveyed to the slitter. Since it was pulled out again, slid, and wound again, the workability was poor, and the tip of the material c to connect the rolling roll to the winder and the tip of the material c from the slitter to the winder were Since it cannot be processed, it becomes a defective product, and the processing yield is also poor.

る。According to the present invention, there is provided a method for shaping a metal strip having a thick section and a thin section between a pair of rolling rolls by passing the metal strip with a long cross-section. When shaping the strip material having a long cross-section with the rolling roll, at the same time, a removing portion is formed on both sides of the strip material, the removal portion being displaced in the plate surface direction of the strip material, and then a pair of cuts prepared. The above-mentioned object is achieved by pressing the removed portion toward the other plate surface of the strip by a roll to separate it from the plate surface. By forming a ridge portion on one peripheral surface of the pair of cutting rolls that conforms to the ridges and valleys formed on the plate surface of the long profiled strip material, the removal portion can be formed by fitting these ridge portions. The long material can be positioned at the time of cutting off.

れる。When the prepared long-section strip material passes between a pair of rolling rolls, the surface shape of the strip material is shaped. The concave line and the convex line are formed in advance so as to form the removed portion which is deviated to one side. The strip with the removed portion shaped is then passed through a cutting roll, and at this time, the removed portion that has shifted out in one plate surface direction and is ejected is pressed by the cutting roll in the other plate surface direction, The pressure causes the root portion of the removed portion to break and separate.

In FIG. 3, reference numeral 1 denotes a long strip-shaped strip material formed of pure copper, copper alloy, permalloy or the like on a profile section having thick and thin portions with a die rolling device (not shown). The long profiled strip material 1 has a surface shape of a pair of rolling rolls 2.
It is shaped by passing between a and 2b. As shown in FIG. 4, one rolling roll 2a has a groove 4 formed therein, and the other rolling roll 2b has a groove 5 formed in a portion corresponding to the central portion of the groove 4. In addition, the ridges 6 and 6 having the same shape and the same width are formed on both sides of the ridge 5, and the ridges 6 and 6 are formed on both outer sides of the ridges 6 and 6 at positions deviating from positions facing the ridge 4. The recesses 7, 7 for forming the removed portion deeper than 5 are formed. In the example shown in the figure, a step 9 is formed in a portion continuing from each of the ridges 6 to the bottom surface of the recess 7, 7, and the height h from the ridge 6 to the step 9 is made equal to the depth i of the ridge 4. I tried to be. Moreover, when these rolling rolls 2a and 2b are set, from the surface of the groove 4 of the rolling roll 2a,
The distance j to the central groove 5 of the rolling roll 2b and the distance k from the surface of the rolling roll 2a to the surface of the recess 7 for forming the removed portion of the rolling roll 2b are made equal.

The distance l between the rolling rolls 2a and 2b was set to 1.05 mm. When the strip 1 is passed between the rolling rolls 2a and 2b, the removing portion 12 protruding toward one plate surface of the strip 1
A profiled strip with a contour is shaped, which is followed by a space 1
After passing between the cutting rolls 13a and 13b set to mm, the removing portion 12 was pushed by the cutting roll in the direction opposite to the plate surface and separated at the position of the constricted root portion 14. The difference in width between the thin-walled portions on both sides of the shaped cross-section strip material 1 that had been shaped was ± 0.03 mm, which was highly accurate. No scratch was found on the surface of the modified cross-section strip material.
