In figure: 1-C type frame; 2-correcting working table; 3-lifting piston; The safe shading ring of 4-; 5-L type support arm; 6-rotational sleeve; The spacing contact block support of 7-; 8-contact block; 9-groove; 10-the first dowel hole; 11-the second dowel hole.
The specific embodiment
As shown in the figure, a kind of safety-type single-column adjusting press-assembly hydraulic press, comprises C type frame 1, on C type frame 1 inner bottom plating, have correcting working table 2, in C type frame 1, have hydraulic cylinder, the lifting piston 3 on hydraulic cylinder stretches out the top board of C type frame 1, in C type frame 1, also have a safety isolated switch unit
Safety isolated switch unit comprises motor, rotational sleeve 6, L-type support arm 5 and safe shading ring 4, motor is positioned at C type frame 1 top, the upper end of the rotating shaft of motor and rotational sleeve 6 is fixed, rotational sleeve 6 stretches out the top board of C type frame 1 straight down, rotational sleeve 6 is connected with L-type support arm 5, L-type support arm 5 one end are fixed with safe shading ring 4, one side L-type support arm 5 is connected with safe shading ring 4, are horizontal sides;
Motor can drive safe shading ring 4 to take rotational sleeve 6 as axis horizontal rotation;
Rotational sleeve 6 sides have spacing contact block support 7, on spacing contact block support 7, are fixed with contact block 8;
On C type frame 1 madial wall, there is groove 9, in groove 9, there is switch, in the time of under safe shading ring 4 turns to lifting piston 3, spacing contact block support 4 is conflicted with C type frame 1 madial wall, be can not being rotated further of rotational sleeve 6, contact block 8 can stretch in groove 9 and make switch open, and now lifting piston 3 can be walked in safe shading ring 4.
