Description of the Related Art When cutting a member to be cut in the above-mentioned shearing machine, the center point of the member to be cut is supported, upper and lower cutting blades are rotated, and the member to be cut is rotated by the rotation to cut the upper part. A means is adopted in which the blade is gradually lowered to perform cutting, and after the cutting is completed, the member to be cut is completely separated by one more rotation (hereinafter referred to as extra rotation), and then stopped. In this case, the member to be cut may have some undulations, and it is necessary to prevent the uncut portion and to perform the extra rotation in order to surely separate the member. As a means for performing this extra rotation, for example, after the upper cutting blade reaches the cutting end position, the cutting is continued for a while by a timer or the like, and then the upper cutting blade is lowered along with the rotation of the upper and lower cutting blades. Means have been taken to stop.

とする。However, the member to be cut is rotated by the rotation of the upper and lower cutting blades. Therefore, when the number of rotations of the cutting blade is constant, the rotation time of one rotation of the member to be cut is large. Is proportional to the diameter of the circular member to be cut. Therefore, if the diameter of the circular member to be cut is small when the timer stops after a certain time by the timer, the extra rotation becomes more than the predetermined rotation, which is wasteful, and in the case of a large diameter, it may not reach the predetermined rotation. , At this time, there is a problem that it cannot be completely cut. Therefore, it is necessary to adjust the timer each time according to the diameter of the circular member, which is troublesome and it is difficult to accurately set the extra rotation. In view of these points, the present invention has an object to set the above-mentioned extra rotation to a predetermined rotation speed by inputting the diameter of the circular member to be cut into the control means.
