Description

За последние годы в металлическом самолетостроении весьма широко дл  соединени  взаимно перпендикул рно расположенных стрингеров с по сами лонжеронов примен ютс  штампованные из дуралюмини  башмаки. Эти башмаки компактны, легки и обладают большой жесткостью, что очень ценно дл  конструкции самолета.In recent years, in metal aircraft manufacturing it has been widely used for connecting mutually perpendicularly located stringers from the side members themselves that stamped duralyumin shoes have been used. These shoes are compact, lightweight and have great rigidity, which is very valuable for the design of the aircraft.

Однако существующий в насто щее врем  способ штамповани  этих башмаков имеет р д недостатков. 1) затрачиваетс  в два-три раза больше дефицитного цветного металла , чем это на самом деле нужно дл  готовой детали; 2) необходимо большое число выт жных переходов с промежуточными отжигами в селитровых ваннах, причем получаетс  больша  затрата смазочных веществ и бензина дл  обмывани  деталей перед отжигом; 3) увеличиваетс  потребность в таре ( щиках) и производственной площади дл  их размещени ; 4) невозможно одновременно заложить в сетку на отжим большое количество башмаков.However, the currently existing method of stamping these shoes has a number of disadvantages. 1) it consumes two to three times more scarce non-ferrous metal than is actually needed for the finished part; 2) a large number of exhaust transitions with intermediate annealing in nitre baths is necessary, and a large expenditure of lubricants and gasoline is obtained for washing the parts before annealing; 3) the need for packaging (boxes) and production space for their placement increases; 4) it is impossible to lay a large number of shoes in the net at the same time.

Новый способ имеет целью устранить эти недостатки путем выполнени  всех операций штамповани  одновременно над двум  плоскимиThe new method aims to eliminate these disadvantages by performing all the punching operations at the same time on two flat

заготовками, располагаемыми в штампах симметрично, причем форма заготовок такова, что никакой обрубки выштампованных башмаков производить не требуетс .blanks placed in stamps symmetrically, and the shape of the blanks is such that no chipping of the stamped shoes is required.

На чертеже фиг. 1 и 2 изображают в двух проекци х башмак дл  соединени  взаимно перпендикул рно расположенных стрингеров с по сами лонжеронов; фиг. 3 - сечение по линии ВВ на фиг. 1; фиг. 4, 5, 6 -башмак дл  взаимно перпендикул рно расположенных профилей в трех проекци х; фиг. 7 - вырубку дл  штамповани  башмаков по фиг. 1-3; фиг. 8 и 9 - перспективный вид матрицы и пуансона дл  выт гивани  бортов у этих вырубок; фиг. 10 и 11 - перспективный вид матрицы и пуансона дл  окончательного оформлени  башмака по фиг. 1-3; фиг. 12 - вырубку дл  штамповани  башмаков по фиг. 4-6; фиг; 13 и 14 - перспективный вид матрицы и пуансона дл  первых операций штамповани  этого башмака; фиг. 15 - перспективный вид заготовки -после штамповани  в матрице по фиг. 13; фиг. 16 и 17 - перспективный вид матрицы и пуансона дл  окончательной операции штамповани  этого башмака.In FIG. 1 and 2 depict in two projections a shoe for connecting mutually perpendicularly arranged stringers with the side members themselves; FIG. 3 is a section along the line BB in FIG. one; FIG. 4, 5, 6 -bashmak for mutually perpendicularly spaced profiles in three projections; FIG. 7 shows a cutting for punching the shoes of FIG. 1-3; FIG. 8 and 9 are a perspective view of a die and a punch for pulling the beads at these cuttings; FIG. 10 and 11 is a perspective view of a die and a punch for finalizing the shoe of FIG. 1-3; FIG. 12 shows a cutting for punching the shoes of FIG. 4-6; fig; 13 and 14 are a perspective view of a die and a punch for the first stamping operations of this shoe; FIG. 15 is a perspective view of the workpiece — after stamping in the die of FIG. 13; FIG. 16 and 17 is a perspective view of a die and a punch for the final punching operation of this shoe.
