Claims

[Scope of utility model registration request]

In the vertical movement mechanism of the press ram, which moves the press ram forward and backward with respect to the press bed by transmitting the forward and backward movement of the piston shaft of the fluid pressure cylinder to the ram rod connected to the upper part of the press ram, a pair of upper and lower toggles are provided on the upper side of the press bed 4. Mechanism plates 9 and 10 are arranged in parallel, and the press ram 5 is supported on the lower toggle mechanism plate 9 in a vertically movable manner, and the upper toggle mechanism plate 10 located on the axis of the press ram 5 is provided with a height adjustment rod. 17 is attached in a height-adjustable manner, and the upper end 20a of the ram rod 20 connected to the press ram 5 is connected to the height adjustment rod 17.
A pair of toggle links 21, 22 formed at the lower end 17a of the same length, one side end 21a, 22 of
a, and the other end portions 21b, 22b of these toggle links 21, 22 are rotatably connected to the tip portion 24a of the piston shaft 24, and the upper end portion 20 of the ram rod 20 is also rotatably connected to the tip portion 24a of the piston shaft 24.
a and the lower end 17a of the height adjustment rod 17, one side end 26a of a pair of holding links 26, 27 which are formed to have the same length and are longer than the pair of toggle links 21, 22. , 27a
are rotatably connected to each other, and these retaining links 26, 2
The other end portions 26b, 27b of 7 are rotatably connected to the pressure cylinder main body 28, and the pair of toggle links 21, 22 extend linearly at the end of the downward movement of the press ram 5. Features a press ram vertical movement mechanism.
