| An increase in stiffness in order to hole a flange of a car can use .Holes a flange can be made by a method of flanging , by which the processes of bending around the edge of the hole to reach stiffness required in the process of assembly .Holes a flange formed with the use of a machine press holes in a plate of increased a flange so that rigidity .Machine fabrication press holes into a flange study the science of the experimental work on duty the end of .A machine press holes a flange done on a steel plate carbon ASTM 1045 as to dimensions 10 x 10 cm , 13 x 13 cm , 16 x 16 cm .The result of the manufacture of a flange holes to get a machine to press a flange holes produce values as stiffness that rises indicated by the value of the deflection plates on a steel plate 10 x 10 cm by 0.07 mm , 13 x 13 cm price rose by 0.18 mm , 16 x 16 cm of 0,70 mm . |
