Title:
METHOD FOR GENERATING TURNING-IN LINE OF BENDING WORK AND BENDING SYSTEM USING SAME METHOD
Document Type and Number:
Japanese Patent JP3222094
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain a method for drawing turning-in lines automatically taking the amount of elongation into consideration matching to die conditions on a development and system therefor.
SOLUTION: In a simulation device 20 for bending work, after a solid shape is generated from the data 21 of drawing viewing from three directions with a solid shape generating processing part 22, a work for forming the edge angle θk of the solid shape is put on a die 9 with a work bending simulation processing part 24 and, based on the bending information Ji consisting of the edge angle θk of each edge of the solid shape, work conditions Wp, die conditions kp or the like, simulating operation in which the work is completely bent to the edge angle θk is executed. The amount α of elongation of the work at this time is determined with an elongation amount calculating processing part 25, it is subtracted from the length of each side of the solid shape with an elongation amount subtracting processing part 28, the development is made with a development generating processing part 28 and a Li-value according to this development is sent out to the side of a press machine with a L-value calculating processing part 29.
