Description
с ручным управлением и блокировочный концевой выкл чатель 11.with manual override and locking limit switch 11.
Механизм прессовани работает -сдедую- щим образом.The pressing mechanism works in the following way.
При работе, машины масло подаетс в поршневую полость дополнительного гидроцилиндра 7, в результате чего поршень 8 со штоком 9 выдвигаетс , и шток 9 входит в поршневую полость цилиндра прессовани 1 и служит ограничителем хода. Цилиндр прессовани 1 работает как обычно, независимо от дополнительного. При необходимости замены включаетс золотник 10, нажима блокировочный концевой выключатель, который предохран ет от преднамеренного включени золотника 10, масло нодинмает поршень 8 со штоком 9, дава возможность поршню 2 со штоком 3 подн тьс на величину S, в результате пресс-плунжер 5 выходит из стакана 6 и легко замен етс другим . После замены с помошью золотника 10 с ручным управлением медленно опускаетс поршень 8, который воздействует на порН1ень 2, опуска его, так как усилие, развиваемое поршнем 8, больше .усили , получаемого от действи давлени на площадь поршн 2 в штоковой полости цили}1дра прессовани 1. После того как пресс-плунжер 5 войдет в стакан 6, а поршень 8 опуститс в крайнее нижнее положение, машина готова к работе.During operation, the oil is supplied to the piston cavity of the additional hydraulic cylinder 7, with the result that the piston 8 with the rod 9 extends and the rod 9 enters the piston cavity of the pressing cylinder 1 and serves as a travel stop. Press cylinder 1 operates as usual, regardless of additional. If replacement is necessary, the spool 10 is turned on, pressing the locking limit switch, which prevents the spool 10 from deliberately turning on, the oil pushes the piston 8 with the rod 9, allowing the piston 2 with the rod 3 to rise by S, as a result the plunger 5 leaves the cup 6 and is easily replaced by another. After replacing the hand-operated spool 10 with the aid of a piston 8, the piston 8 is lowered, which acts on the poreN 2, lowering it, since the force developed by the piston 8 is greater than the force generated by the pressure on the piston 2 in the piston rod of the cylinder cavity} 1dr 1. After the press plunger 5 enters the cup 6 and the piston 8 is lowered to the lowest position, the machine is ready for operation.
Предлагаемый механизм позвол ет увеличить производительность машины, срок службы прессующих плунжеров и упростить обслуживание машины.The proposed mechanism allows to increase the machine productivity, the service life of the pressing plungers and simplify the maintenance of the machine.
