Description of the Related Art Conventionally, in a side trimmer incorporated in a continuous processing line or the like for pickling after rolling, when a trouble such as chipping occurs during a trimming operation, usually, as shown in FIG. 4, the trimming was continued until a position where the side clipping 72 of the strip 71 was performed or a position where the following material 73 became narrower than the preceding material 74 as shown in FIG. 4, and the line was stopped when reaching the position. . Japanese Patent Publication No. 5-55247 discloses that a blade is horizontally rotated and a strip is horizontally moved in a width direction of a strip, and a strip being trimmed enters the inside of the strip once and then moves along a cutting curve which moves outward. A turret-type side trimmer cutter knife changing method for cutting from a strip is disclosed.

供することを目的とする。However, continuing the trimming to the position where the side clipping 72 is made or the position where the following material 73 becomes narrow even after the trouble occurs, wastes the strips 71 and 75. Not
When chipping occurs, there is a problem that the quality of the product deteriorates. In the case of Japanese Patent Publication No. 5-55247, there is a problem that a turning mechanism is always required and the device is complicated. Also, if you get through the strip,
Unless the angle between the blade and the strip is controlled to an appropriate value, there is a problem that a chip change occurs due to a sudden load change. The present invention has been made in view of such circumstances,
An object of the present invention is to provide a high-speed retracting method of a cutting tool at the time of trimming, which enables the cutting tool to be separated from the strip with a small loss of the strip.

機構が簡単になる。Referring to FIGS. 1 and 2, a method for retreating a cutter at a high speed during trimming according to an embodiment of the present invention will be described. As an example, a strip 10 made of a steel material and having a thickness of 0.6 mm (usually having a thickness of about 0.1 to 9.5 mm) is fed in the x direction at a speed of 200 mpm, and the toe-in angle is set to-.
While cutting both sides of the strip 10 at a constant width with the blade 11 set to 0.2 degrees (usually in the range of -1 to 0 degrees), the running distance is changed due to the occurrence of blade chipping or the like.
When the blade 11 is detached from the blade (the right half of the strip is described), first, the toe-in angle of the blade 11 and the feed speed of the strip 10 are kept as they are, and the blades 11 on both sides are moved in the y direction (outward direction of the plate width). ) To 20mm
/ Sec. As shown in FIG. 2, the blade 11 is maintained at a toe-in angle of -0.2 degrees and the strip 1
0 is cut in a straight line in an oblique direction, and the cutting tool 11 passes through the end of the strip 10. By doing so, the blade 11 is not chipped when cutting through the strip 10, and the loss of the strip 10 can be greatly reduced. Further, in this method, since the side trimmer does not require a turning mechanism of the blade, the mechanism of the side trimmer is simplified.

る。According to the first aspect of the present invention, in the method for retreating a blade at a high speed during trimming, the blade is moved outward in the width direction of the blade in accordance with the feed speed of the strip while maintaining the toe-in angle of the blade. The cutting tool can be released from the strip while traveling a certain distance in the direction. Therefore, there is no need to continue trimming to the position where the side clipping or the trailing material is narrowed in order to separate the blade from the strip as in the related art, and the loss of the strip can be greatly reduced. The retracting time is short because the blade is retracted at a high speed, so that it is possible to respond quickly to troubles and the like. Further, if the toe-in is performed with a fixed toe-in, the mechanism of the apparatus is simplified, and the blade can be retracted at high speed even with a side trimmer having no turning mechanism and toe-in applying mechanism.
