Description
На двух крайних конических опорных шейках эксцентрикового вала установлены сферические рол коиодшипники 22, зафиксированные гайками 23.On the two extreme conical bearing journals of the eccentric shaft are mounted spherical roller bearings 22, fixed with nuts 23.
Ползун 11 установлен на станине 1 в направл ющих качени 24.The slider 11 is mounted on the frame 1 in the rolling rails 24.
В опоре 10 имеютс вертикальные каналы 25, а в ползуне 11 установлены обратные клапаны, состо щие из шариков 26 и пружин 27, сообщающиес с резервуаром 28 дл жидкой смазки. Дл удержани смазки и ее очистки установлена перегородка 29.In the support 10 there are vertical channels 25, and in the slider 11 check valves are installed, consisting of balls 26 and springs 27, communicating with reservoir 28 for liquid lubrication. A partition 29 is installed to hold the lubricant and clean it.
Пресс работает следующим образом.The press works as follows.
При вращении эксцентрикового вала 2 на холостых ходах поверхности нижних секторов 7 перекатываютс по поверхност м роликов 9, описыва дугу радиусом, проведенным из центра верхней оси 16 нолзуна , при этом круговой шатун 4 с верхним 5 и нижним 7 сектором совершает качательные движени . При совершении технологической операции под действием нагрузки ролики 9 упруго деформируютс , в результате чего зазор б между сектором 7 и опорой ползуна выбираетс , а усилие пресса передаетс через ползун 11 и круговые шатуны 4 на эксцентриковый вал 2. Смазка к трущимс поверхност м поступает автоматически из резервуара 28 через каналы 25 и обратные клапаны 26, 27.When the eccentric shaft 2 rotates at idle, the surfaces of the lower sectors 7 roll over the surfaces of the rollers 9, describing an arc with a radius drawn from the center of the upper axis 16 of the slide, while the circular rod 4 with the upper 5 and lower 7 sector performs swinging movements. When performing a technological operation under the action of a load, the rollers 9 are elastically deformed, as a result of which the gap b between sector 7 and the support of the slider is selected, and the pressing force is transmitted through the slider 11 and the circular connecting rods 4 to the eccentric shaft 2. The lubricant to the surfaces is automatically transferred from the reservoir 28 through channels 25 and check valves 26, 27.
