V-bending operation

Determine the bending force required in Problem 20.11 if the bend is to be performed in a V-die with a die opening width dimension = 1.25 in. The material has a tensile strength = 70,000 lb/in2.

 

Problem 20.11

An L-shaped part is to be bent in a V-bending operation on a press brake from a flat blank 4.0 in by 1.5 in that is 5/32in thick. The bend of 90 is to be made in the middle of the 4.0 in length.

(a) Determine the dimensions of the two equal sides that will result after the bend, if the bend radius = 3/16 in. For convenience, these sides should be measured to the beginning of the bend radius. (b)Also, determine the length of the part’s neutral axis after the bend.

(c) Where should the machine operator set the stop on the press brake relative to the starting length of the part?
