Description

лени м шкалы дл обрезки фаски с заданным уклоном и жестко заиреллена в нем, а нож 7 рычага 6 приподн т над заготовкой 15 щрн ломощи yraoipa 8 и пружины 16.the scale for chamfering with a given inclination and rigidly fastened in it, and the knife 7 of the lever 6 is raised above the workpiece 15 of the yraoipa 8 and the spring 16.

Штамш рНботает следующим образом. Заготовка 15 подаетс до упора 8. При ходе вниз ползуна (не локазан) дрижим 12 прижимает заготовку 15 к неподвижному ножу 2, предотвраща ее смещение в процессе резани , а ролик 14 толкател 13 нажимает на (Свободный конец рычага 6. При этом в |результате движени последнего по ради,усу R воКруг оси 9 прансходит срезание фаоки с pa3iMeipaiMH, онредел емыми в зависимости от угла наклона а .и величины радиуса J.Strain pH is as follows. The workpiece 15 is fed up to the stop 8. When the slider is down (not locally), the drive 12 presses the workpiece 15 against the stationary knife 2, preventing it from moving during the cutting process, and the roller 14 of the pusher 13 presses on (Free end of the lever 6. At the same time, for the latter to travel along the radius, usu R around the axis 9, the cutting of the façades from pa3iMeipaiMH, which can be determined depending on the angle of inclination ai and the radius value J.

При ходе вверх ползуна пресса толкатель 13 освобождает рычаг 6 от воздействи , и ой возвращаетс в исходное положение при помощи пружин 16 и yinopa 8. Сн тие фаоак на заготовках, превышающих длину режущих инструментов штампа , производитс за несколько переходов.During the upward movement of the press ram, the pusher 13 releases the lever 6 from the action, and oi returns to its original position with the help of springs 16 and yinopa 8. The removal of faoac on workpieces exceeding the length of the punch cutting tools is performed in several transitions.

Изобретение позвол ет подучать фаски на издели Х с разл1ичным углом наклона, что повышает технологические возможности штампа.The invention allows chamfering on the product X with a different angle of inclination, which enhances the technological capabilities of the stamp.

Claims

1. A shtamp for manufacturing products with chamfering, containing a bottom plate, a bracket placed on it with a hinge mounted on it by means of an axis with the possibility of swinging in a vertical plane with a lever carrying a knife, fixed knife on the bottom plate

with a cutting edge, a top plate with a pusher placed on it with the ability to interact with the bottom plate lever, and an emphasis, characterized in that, in order to expand technological capabilities due to the possibility of chamfering at different angles of inclination, the bottom plate bracket is made with arc-shaped grooves, and the axis of swing arm installed in arc-shaped grooves

the bracket is movable relative to them and is equipped with a fizsator position relative to the grooves of the bracket.

2.Stamm according to claim 1, characterized in that the slots of the bracket are made according to

arc of a circle, the center of which is located on the cutting edge of a fixed knife.
