摘要： A method for determining a heating line for bending a steel plate includes the steps of: placing a virtual pattern on a virtual plate; rolling the plate along a frame line from a reference position to contact the plate at two points on the plate; rolling the steel plate back to the reference position; obtaining straight lines connecting the contact points; determining a heating point relative to a reference point; repeating the same steps while contacting the contact points on a reference point side; drawing straight lines from a certain heating point on a certain line to heating points on other lines; examining the degree of parallelism between each straight line and a roller line; grouping the relevant heating points as the same group; and connecting the heating points of the same group by a straight line or a curve.

摘要： An automatic plate bending system using high frequency induction heating has many universal poles for bearing a steel plate, a member to be heated, by supporting it from below, the height positions of front end portions of the universal poles themselves being adjustable, and automatically moves a high frequency heating coil of a high frequency heating head above the steel plate, which is placed on the universal poles, along predetermined heating lines while retaining a constant clearance between the high frequency heating coil and the surface of the steel plate, whereby the steel plate is heated and automatically bent into a desired shape.

摘要： 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.
