Title: Hand-bent blank layout structure of sheet metal parts
Inventor: MIZUGUCHI TAKANORI
IPC: B21D5/01
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To secure the accuracy of the position to bend a sheet by hand, and to bend the sheet with excellent appearance by forming a notched corner of acute angle along the folding line on an end of a slit. SOLUTION: When a sheet metal 30 provided with a notched corner 21 of acute angle in an end of a slit 20, the stress as indicated in the explanatory auxiliary line 29 to show the stress density is generated. Because the stress is concentrated on the line to connect the notched corners 21 of acute angle to each other, the folding position is limited on the line to connect the notched corners 21 of acute angle, and the positional accuracy in folding is improved. The hand-bent angle of the notched corners 21 of acute angle is preferably smaller than 90 deg. and larger than 30 deg.. The more acute the angle is, the more the stress is concentrated, but if the angle is too acute, the width of the slit 20 is apparently reduced, and the sheet can not be bent with excellent appearance. The slit 20 can be easily worked using, for example, a laser beam machine.
