CUTTING METHOD AND CUTTING APPARATUS

摘要

Provided is a technique capable of accurately cutting steel sheets of various shapes into desired shapes. A cutting method is a method for cutting a steel sheet by using a nibbler having a cylindrical case, a punch housed inside the case, and a die provided below the case, the nibbler making the punch continuously punch the steel sheet while moving. The cutting method includes: providing a guide member in the vicinity of the die of the nibbler located at a cutting position along a moving path of the nibbler, the guide member having a first guide surface for restricting movement of the nibbler from the cutting position to a first side of a direction perpendicular to a traveling direction and a top-bottom direction of the nibbler by contact with a side surface of the die; and moving the nibbler along the guide member.

1. A cutting method for cutting a steel sheet by using a nibbler having a cylindrical case, a punch housed inside the case, which reciprocates in a top-bottom direction, and a die provided below the case, the nibbler making the punch continuously punch the steel sheet fed between the case and the die while moving, the cutting method comprising:
providing a guide member in the vicinity of the die of the nibbler located at a cutting position along a moving path of the nibbler, the guide member having a first guide surface for restricting movement of the nibbler from the cutting position to a first side of a direction perpendicular to a traveling direction of the nibbler and the top-bottom direction by contact with a side surface of the die of the nibbler located at the cutting position; and moving the nibbler along the guide member.
