    • A method and a system for determining a heating point and a heating line in steel plate bending place a virtual wooden pattern on a virtual steel plate; roll the wooden pattern or steel plate along a frame line from a reference position to contact the wooden pattern and steel plate at two points A, B on the steel plate and C, D on the wooden pattern; roll the wooden pattern or steel plate in the reverse direction for return to the reference position; obtain straight lines U, V connecting the contact points A, B and C, D, respectively; determine a heating point relative to a reference point based on an intersection point of the straight lines U, V; repeat the same steps while contacting the contact points A, C on a reference point side to use their contact point as a new reference point, to determine respective heating points along a specific line up to the end of the steel plate; draw straight lines from a certain heating point on a certain line to heating points on other lines based on the determined heating points; examine the degree of parallelism between each straight line and a roller line; if the degree is within a predetermined range, group the relevant heating points as the same group; and connect the heating points of the same group by a straight line or a curve to determine a heating line.
    • 用于确定钢板弯曲加热点和加热线的方法和系统将虚拟木制图案放置在虚拟钢板上; 将木制图案或钢板沿着框架线从参考位置滚动,以钢板上的两个点A,B和木头图案上的C,D接触木制图案和钢板; 沿相反方向滚动木纹或钢板返回参考位置; 分别连接接点A,B,C,D的直线U,V; 基于直线U,V的交点确定相对于参考点的加热点; 重复相同的步骤,同时接触参考点一侧的接触点A,C,以使其接触点作为新的参考点,以确定沿着钢板端部的特定线路的各个加热点; 根据确定的加热点将直线从某一线上的某个加热点拉到其他管线上的加热点; 检查每条直线与滚线之间的平行度; 如果程度在预定范围内,则将相关加热点组合为同一组; 并通过直线或曲线连接同一组的加热点,以确定加热线。
