The invention discloses a die change device which comprises a workbench and a supporting plate, as well as a frame arranged below the supporting plate, wherein a die is arranged in the workbench, and the workbench is supported on the supporting plate; the die change device further comprises a guide rail support and a hydraulic cylinder; the frame penetrates through the front part and rear part of the fixed part of the hydraulic cylinder, the fixed part of the hydraulic cylinder is fixedly supported on the frame, and the movable part of the hydraulic cylinder is connected with the workbench through a connecting part; and the guide rail support is arranged on one side of the movable part and comprises a support cross beam and support legs, one side of the support cross beam is fixedly connected with the supporting plate, the height of the top surface of the support cross beam is equal to the that of the top surface of the supporting plate, and the bottoms of the support legs are supported on the ground. By adopting the die change device, the workbench can be safely and quickly pulled out of and pushed into a machine body, thereby facilitating the replacement of the die of the hydraulic machine. The invention further discloses a medium and small-sized hydraulic machine which comprises the machine body, an electrical control system and a hydraulic control system, wherein the die change device is utilized as the machine body, and the die change device is connected with the bottom of the machine body. The hydraulic machine also has the corresponding technical effects.
Description
technical field [0001] The invention relates to the technical field of hydraulic presses, in particular to a mold changing device for medium and small hydraulic presses. The present invention also relates to a hydraulic machine comprising the above-mentioned mold changing device. 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 transmit energy to realize various processes. According to the type of liquid that transmits pressure, hydraulic presses are divided into two categories: hydraulic presses and hydraulic presses. The total pressure produced by the hydraulic press is relatively large, and it is often used for forging and stamping. [0003] In addition to being used for forging and forming, hydraulic presses can also be used for straightening, pressing, packing, briquetting and pressing. The usual hydraulic press mainly consists of three parts: mechanical structure, hydrau...
