Description
Изобретение относитс к волочениюThis invention relates to the drawing
Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс роликова головка , включающа кольцевой корпус, нажимной механизм, выполненный в виде двуплечих рычагов с установленными на них роликаго CUНедостатком известного устройства вл етс ограниченный диапазон прот гиваемых изделий.The closest in technical essence and the achieved result to the invention is a roller head including an annular body, a pressure mechanism made in the form of two shoulders with roller mounted CU. The disadvantage of the known device is the limited range of products being pulled.
Целью изобретени вл етс увеличение диапазона прот гиваемых изделий . The aim of the invention is to increase the range of products to be treated.
Поставленна цель достигаетс тем, что в роликовой головке, включающей кольцевой корпус, нажимной механизм, выполненный в виде двуплечих рычогов с установленными в них роликами, нажимной механизм снабжен установленными на корпусе кассетой и гидроприводом, шарнирно св занными с двуплечими рычагами, а на корпусе установлен с -возможностью перемещени вдоль оси корпуса упор, контактирующий с гидроприводом.The goal is achieved by the fact that in a roller head, which includes an annular body, a pushing mechanism made in the form of two shoulders levers with rollers installed in them, the push mechanism is equipped with a cassette mounted on the body and a hydraulic actuator pivotally connected with two shoulders -the ability to move along the axis of the body, the stop in contact with the hydraulic drive.
Кроме того, св зь гидропривода с двуплечими рычаггиии выполнена посредством регулируёкых по длине шатунов .. .In addition, the coupling of the hydraulic drive with two shoulders of leverage is performed by means of connecting rods along the length ..
На фиг. 1 изображена роликова головка в положении заправки, продольный разрез ; на фиг. 2 - роликова головка в рабочем положении.FIG. 1 shows a roller head in the refueling position, longitudinal section; in fig. 2 - roller head in working position.
Роликова головка состоит из закрепленного неподвижно на фундаменте кольцевого корпуса 1, на котором . смонтирован гидроцилиндр, включамдий подвижно установленный корпус 2с крышкой 3 и уплотнени ми 4 и неподвижно установленный поршень 5, раздел ющий гидроцилиндр на полости А и Б. На конце кольцевого jcopnyca-1 закреплена снаружи сменна кассета The roller head consists of fixedly fixed on the base of the ring body 1, on which. a hydraulic cylinder is mounted, including a movably mounted body 2 with a cover 3 and seals 4 and a fixed piston 5, which separates the hydraulic cylinder in cavities A and B. At the end of the annular jcopnyca-1 the removable cartridge is fixed outside
15 6 стопорными болтами 7, а изнутри сменна центрирук ца втулка 8. Между крьмкой 3 и кассетой 6 на корпусе 1 установлен с возможностью перемещени упор 9 в виде резьбовой гайки, 15 6 with retaining bolts 7, and from the inside a replaceable centering sleeve 8. Between krmka 3 and the cassette 6 on the housing 1, the stop 9 is mounted in the form of a threaded nut,
20 регулирунвдий величину хода гидроцилиндра . Кассета б имеет проушины 10,. в которых ос ми 11 закреплены с возможностью поворота в плоскости оси волочени двуплечие рычат и 12, на 20 rynagruundviy the stroke of the hydraulic cylinder. Cassette b has eyelets 10,. in which axes 11 are fixed with the possibility of rotation in the plane of the axis of the dragging, two shoulders roar and 12, on
25 одном плече которых установлены профилирующие ролики 13. Другие гшечи рычагов 12 посредством шатунов 14, состо щих из вилок 15 наконечников 16, соединены с крышкой 3, на терце 25 one shoulder of which the profiling rollers 13 are mounted. The other arms of the levers 12 are connected by means of connecting rods 14 consisting of forks 15 tips 16 and connected to the cover 3, on the ground
