Abstract

The invention relates to the technical field of hydraulic machines and discloses a protection device used for a hydraulic machine. The protection device comprises a base. A worktable is fixedly installed on the top of the base. Stand columns are fixedly installed on the top of the worktable, and an oil cylinder device is fixedly installed on the tops of the stand columns. A pressing seat is fixedly connected to the bottom of the oil cylinder device. Movable communication grooves are formed in the side face of the worktable, and protection plates are movably installed on the side faces of the worktable. By means of the protection device used for the hydraulic machine, due to the cooperation of damping devices, hollow elastic rods, L-shaped clamping seats and tension springs, in the processthat the pressing seat moves downwards slowly, the protection plate can be unlocked, and therefore the problem that a part is broken and outburst due to self problems, and the human body is hurt is avoided; and meanwhile, the output ends of the damping devices can be used for driving connecting rods of alarm devices to move, the alarm devices can conduct alarming, and the protection plates can warn people to get away from the pressing seat before unlocking.

Description

technical field [0001] The invention relates to the technical field of hydraulic machines, in particular to a protective device for hydraulic machines. Background technique [0002] A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to realize various processes. The hydraulic press is generally composed of three parts: the machine (main machine), the power system and the hydraulic control system. The hydraulic press is classified into Valve hydraulic presses, liquid hydraulic presses, engineering hydraulic presses. [0003] The hydraulic press can be used for forging, stamping, cold extrusion, straightening, bending, and flanging. During the operation of the hydraulic press, when the press seat gradually exerts pressure on the workpiece, or when two parts are mated under the hydraulic press, it may Due to the uneven force or the material of the parts, or because the friction between the workpi...
