Abstract

Способ штамповки заключается в следующем. В заготовке сначала пробивают отверстия под палец для крепления петли люка, затем производят вырубку по контуру развертки детали, производят отжиг до необходимой твердости, после отжига заготовку подвергают галтовке, подают заготовку в гибочный штамп и поперек волокон металла, под угол 90° к горизонтальной плоскости заготовки, формуют проушины, затем пробивают крепежные отверстия на плоской части отштампованной детали. В гибочном штампе производят формовку проушин по меньшей мере двух зеркально расположенных заготовок. Устройство для штамповки державки петли люка грузового вагона содержит пуансон, установленный на верхней плите, матрицу, установленную на нижней плите и выполненную из раздельных секций, державку, на горизонтальной поверхности которой установлены заготовки деталей и упоры, толкатель.The method of stamping is as follows. In the workpiece, first punch holes under the finger for fixing the hinge loop, then cutting along the contour of the part sweep, annealing to the required hardness, after annealing, the workpiece is subjected to tumbling, the workpiece is fed into the bending punch and across the metal fibers at an angle of 90 ° to the horizontal plane of the workpiece , form the eyes, then pierce the mounting holes on the flat part of the stamped part. In the bending stamp, the eyes are molded into at least two mirror-shaped blanks. A device for punching a hinge of a hatch of a freight car contains a punch mounted on the top plate, a matrix mounted on the bottom plate and made of separate sections, a holder, on the horizontal surface of which the workpieces of parts and abutments are installed, the plunger.
