Description
Изобретение относитс к устройствам дл удалени внутреннего грата при изготовлении продольно-сварных труб малого диаметра.The invention relates to devices for removing internal burrs in the manufacture of longitudinally welded pipes of small diameter.
Цель изобретени - повьшение надежности работы устройства за счет повьшёни устойчивости его положени на линии грата.The purpose of the invention is to increase the reliability of the device by increasing its stability on the line of flash.
На фиг.1 изображено предлагаемое устройство в продольном сечении свариваемой трубы в период срезани грата; на фиг.2 - то же, в период отвода резца из зоны резани ; на фиг.З - сечени А-А и Б-Б на фиг.1; на фиг.4 - схема распределени сил на рычаге, соответствуклца положению инструмента на фиг.2. Fig. 1 shows the proposed device in the longitudinal section of the pipe being welded during the shearing of burrs; Fig. 2 - the same, during the period of withdrawing the cutter from the cutting zone; on fig.Z - sections aa and bb in figure 1; Fig. 4 is a diagram of the distribution of forces on the lever, corresponding to the position of the tool in Fig. 2.
Устройство дл срезани внутреннего грата состоит из корпуса 1 ,. который располагаетс внутри трубы 2 на упругих.опорах 3 и 4 в виде плоских пружин арочного профил . В корпусе 1 выполнен сквозной продольный . паз 5, в котором на оси 6 размещен рычаг 7, На рычаге 7 закреплен резец 8 дл удалени грата 9. Канал 10 служит дл отвода стружки. Рычаг 7 подпружинен относительно опорной поверхности трубы пружиной 11 арочного про ,фил . На конце рычага 7 следом за опорной пружиной 11 на оси 12 установлен копирный ролик 13. В передней части корпуса 1 расположена направл ю1ца канавка 14, предназначенна дл ориентации резца 8 по линии грат 9. На другом конце корпуса 1 закреплен резец 15, служащий дл удалени оставшегос грата 9. Корпус 1 закреплен на конце инструментальной т ги 16 Устройство работает следующим образом .The device for cutting internal flash consists of body 1,. which is located inside pipe 2 on resilient supports 3 and 4 in the form of flat springs of an arched profile. In the housing 1 is made through the longitudinal. a groove 5 in which lever 7 is placed on axis 6; Cutter 8 is fixed on lever 7 to remove burrs 9. Channel 10 serves to remove chips. The lever 7 is spring-loaded relative to the support surface of the pipe with a spring 11 arched pro, fil. At the end of the lever 7, following the support spring 11, an axle 12 is mounted on the axis 12. In the front part of the housing 1, there is a direction groove 14 for orienting the cutter 8 along the rake line 9. At the other end of the housing 1 there is a cutter 15 that serves to remove the remaining burr 9. Case 1 is fixed at the end of the instrumental draft 16 The device operates as follows.
Грат 9, образованный на односторонне движущейс трубе 2 (по стрелке ) , проходит по канавке 14 и срезаетс резцом 8. Копирный ролик 13 контактирует со стенкой трубы и вращаетс за .счет сил трени . В рабочем положении (фиг.2) ролик 13 опускает рычаг 7 вниз, снима пружину 11. Резец 8 выходит из зоны резани и осуществл ет отрыв стружки.The burr 9 formed on the one-way moving pipe 2 (along the arrow) passes along the groove 14 and is cut by the cutter 8. The copy roller 13 contacts the pipe wall and rotates due to friction forces. In the working position (Fig. 2), the roller 13 lowers the lever 7, removing the spring 11. The cutter 8 moves out of the cutting zone and carries out chip separation.
В опущенном положении на рычаг (фиг.4) действуют силы: Р - сила воздействи ролика, приложенна в точке И, соответствует месту расположени оси ролика;In the lowered position, the forces acting on the lever (Fig. 4): P - force of the roller applied at the point I, corresponds to the location of the axis of the roller;
Pg - усредненна сила действи опорной пружины 11 в сжатом состо нии , приложенна в точке П.Pg is the averaged force of the action of the support spring 11 in a compressed state applied at the point P.
Сила Р-г т ги и с ла Р резани резца 15 воспринимаетс корпу.Ьом 1 устройства и на привод рычага 7 вли ни не оказывают. Усредненные силы PJ и Р упругих опор 3 и 4, приложенные в точках М и С, прижимают корпус 1 к базовой поверхности трубы. Точка Н, соответствуимца месту расположени оси ролика, представл ет собой жесткую опору, относительно которой создаетс момент силы Р , который посредством рычага стремитс прижать корпус 1 к базовой поверхности трубы совместно с силами Pj и Р4 The strength of the Rgt gi and la la cuts of the cutter 15 is perceived by the case of the device 1 and the drive of the lever 7 is not affected. The averaged forces PJ and P of the elastic supports 3 and 4, applied at points M and C, press the body 1 to the base surface of the pipe. Point H, corresponding to the location of the axis of the roller, is a rigid support, against which a moment of force P is created, which by means of a lever tends to press body 1 to the base surface of the pipe together with forces Pj and P4
Таким образом, предлагаемое устройство повышает устойчивость устройства на линии грата и надежность его работы. Рациональное распределение усилий на приводе резца устройства повышает производительность процесса срезани внутреннего грата.Thus, the proposed device increases the stability of the device on the line of debts and the reliability of its work. The rational distribution of forces on the drive cutter device improves the performance of the cutting process of internal flash.
