The working principle of the invention is as follows:

the screw sleeve 16 is connected with the guide post of the main drive, so that the slide block can do up-and-down reciprocating motion along the guide rail of the upright post under the action of the connecting rod mechanism. The coupler worm 18 is connected with a speed reducing motor, the speed reducing motor drives the worm 18, the worm wheel 11 and the adjusting screw rod 15 to rotate, the adjusting screw rod 15 is driven to move up and down in the screw rod sleeve 16, the adjusting screw rod 15 drives the piston 2, the stop block 20 and the cylinder body 1 to move, the cylinder body 1 is fixed on the sliding block through the double-headed bolt 6, the sleeve 7 and the hexagon nut 8, and therefore the sliding block and the cylinder body move together, and die filling height adjustment of the press machine is achieved.

When the press works normally, the piston 2 opens a certain space under the action of pre-pressure and is positioned by the stop 20. When the press machine is overloaded, high-pressure oil in the high-pressure cavity B is quickly discharged, so that the slide block is lifted, and meanwhile, the slide block stops running, so that the press machine and the die are protected from being damaged due to overload.

The invention has two functions of die height adjustment and hydraulic protection, the transmission mechanism is a worm gear and worm pair, and the worm gear drives the adjusting screw rod to rotate in the screw rod sleeve through a flat key, thereby realizing the die height adjustment function; the hydraulic mechanism is provided with a high-pressure cavity for overload protection of the press machine formed by a cylinder body and a piston, so that the hydraulic protection function is realized.
