ンス式過負荷安全装置。A hydraulic chamber 17 under the ball seat 15 and an oil tank 18 are formed in the slide 10 of the press machine 1, a pump 19 and a safety valve 20 are attached to the slide 10, and the hydraulic oil in the oil tank 18 is pumped to the safety valve 20 by the pump 19. The hydraulic pressure chamber 17 is pressurized to a set pressure through the inlet chamber 21 of the safety valve 20, and the hydraulic oil in the hydraulic chamber 17 is returned to the oil tank 18 through the inlet chamber 21, valve body 24, and outlet chamber 25 of the safety valve 20 in the event of overload. In a hydraulic balanced overload safety device for a press machine, the inlet hole 27 of the oil tank 18 is opened near the inlet/outlet hole 26 of the hydraulic chamber 17, and the mounting side surface 22a of the main body 22 of the safety valve 20 is opened.
The inlet end 21a of the inlet chamber 21 and the outlet end 25 of the outlet chamber 25
a and the inlet end 2 of the inlet chamber 21 of the safety valve body 22.
The mounting side surface 22a of the safety valve body 22 is fixed to the slide 10 with the outlet end 25a of the outlet chamber 25 directly communicating with the inlet/outlet hole 26 of the hydraulic chamber 17 and the outlet end 25a of the outlet chamber 25 with the oil tank inlet hole 27. A hydraulic balanced overload safety device for press machines.
