63 move up and down in oil cylinder 61, when push plate 63 moves down, since the unidirectional cutoff of the first check valve 10 acts on, and oil cylinder 61
Interior hydraulic oil will not enter fuel reserve tank 13 from fuel sucking pipe 7, but enter fuel reserve tank 13 from flowline 5, but due to spring
95 elastic force will push sliding panel 91 to make the hydraulic oil in flowline 5 can not be from the outlet by guide rod 92 under normal pressure
Into in fuel reserve tank 13, but enter in fuel reserve tank 13 from small flowline 11, under normal pressure, sliding panel 91 is will not to touch
To limit switch 12, when push plate 63 moves up, since the unidirectional cutoff of the second one-way valve 8 in flowline 5 acts on, liquid
Pressure oil will enter in oil cylinder 61 from fuel sucking pipe 7, small since pressure is excessive when push plate 63 moves down in pressure overload
Flowline 11 will be unable in time be discharged into pressure in fuel reserve tank by hydraulic oil, and at this moment excessive pressure will impact-sliding plate
91, it makes it through guide rod 92 and drives fixed plate 94 that the elastic force of spring 95 is overcome to move right in adjustment barrel 93, when sliding panel 91
Touch limit switch 12, it will the power supply of cut-out pressure mechanomotive force before sliding block 3 does not reach workbench 1 makes it stop work
Make, thus protect press machine against damages, in addition, since the limiting pressure that the object to be processed needs is different, it can be with people
Work, by adjusting adjusting rod 97, makes it that thread plate 96 be driven to move left and right the size for carrying out control limit pressure in cavity 15.
