Claims (1)
ψo = (0,5...0,6)ψк;
для вогнутых деталей седловидной формы - краевых по ширине частей заготовки, соответствующих углам облегания в осевом направлении ψ
ψ
где ψк - конечный угол облегания в осевом направлении. Положительный эффект: повышение точности и равнопрочности получаемых деталей, возможность изготовления обшивки за один переход вместо двух или большего числа переходов с промежуточными термообработками при изготовлении традиционными способами.The method of coating sheet blanks refers to the processing of metals by pressure. The invention provides the possibility of improving the quality of the lining of linings, reducing production costs. The essence of the invention: at the stage of stitching until the blanks fit fully to the punch, they are processed by pulsed electric current: for parts of convex shape, the central width of the part of the workpiece corresponding to the angle of fit in the axial direction направлении o
ψ o = (0.5 ... 0.6) ψ k ;
for concave saddle parts - edge-wide parts of the workpiece corresponding to the corners of fitting in the axial direction ψ
ψ
where ψ to - the final angle of fit in the axial direction. Positive effect: an increase in the accuracy and equal strength of the parts produced, the possibility of making the casing in one transition instead of two or more transitions with intermediate heat treatments in the manufacture of traditional methods.
