The invention discloses an oil pressure type hydraulic press. The bottom of an upper semicircular beam is provided with a first oil cylinder, a piston is arranged in the first oil cylinder, the lowerend surface of the piston is connected to a piston rod, the piston rod is connected to a movable beam, the machine body corresponding to the left and right sides of the movable beam is provided with vertical tracks, the left and right sides of the movable beam are respectively slidably connected to the corresponding tracks, the bottom of the movable beam is provided with an upper die holder, a lower die holder is mounted right below the upper die holder, the periphery of the bottom of the lower die holder is connected to a lower semicircular beam by a cylindrical support column, the hollow part of the cylindrical support column on the lower semicircular beam is provided with a second oil cylinder, a telescopic rod of the second oil cylinder is connected to a buffer plate by springs, the lower die holder is provided with a pressure sensor, the pressure sensor is electrically connected to the switch of a high pressure oil pump by an oil pump switch controller, and the high pressure oil pump is communicated with an oil cavity by an oil pipe. The oil pressure type hydraulic press is compact in structure, large in support strength, stable in workpiece pushing, and good in oil cylinder sealability.
Description
technical field [0001] The invention belongs to the technical field of hydraulic machinery equipment, and relates to an oil pressure hydraulic machine. Background technique [0002] The oil hydraulic press is a machine that uses oil as the working medium to transfer energy to realize various processes, such as straightening, pressing, packaging, briquetting, pressing plates, etc. The lower mold base and the lower beam of the existing hydraulic hydraulic press are mostly connected by columns. The columns need to meet the requirements of high pressure strength, so the diameter needs to be thicker, which makes the hydraulic machine bulky and heavy. After the workpiece is processed, use When the oil cylinder below the lower mold base pushes out the workpiece, the impact force generated is easy to damage the workpiece; in addition, it is required to push the oil cylinder that pushes down the upper mold base to generate greater force, and thus the pressure in the oil chamber is re...
