The main technical parameter of free forging hydraulic press Free die hydraulic press is the main equipment for heavy forging, which is suitable for single piece or small batch production. Based on the principle of hydrostatic pressure transmission, under the effect of hydraulic cylinder, with emulsion as media,via upper and lower anvil and some simple universal tools, it enables plastic deformation of the steel ingot or stock, in order to improve inner quality and achieve the size of desired shape. name & parameter20MN free die hydraulic press31.5MNfree die hydraulic pressNominal press20MN31.5MNpress stylefour pillar upper transmissionfour pillar upper transmissiontransmission stylepump-accumulator stationpump-accumulator stationpress grade10/20MN15/31.5MNworking mediumwater(emulsion)water(emulsion)medium pressure32Mpa32Mpadistance of clearance2675mm4060mmCenter distance of pillar2400×1200mm3500×2000mmSize of the work bench4000×1500mm6000×2000mmMax. stroke1400mm2000mmSpeed of the walking beamAirborne:300mm/sPressurize:150mm/sAirborne:300mm/sPressurize:150mm/sForging timesnormal forging16/mfast forging 60/mnormal forging16/mfast forging 60/mStroke of the work benchLeft:1500mm right:1500mmLeft:3000mm right:3000mmcontour sizeabove ground height: about 8000mmUnderground depth: 3000mmPlane size 11400×4100mmabove ground height: about 11200mmUnderground depth 5000mmPlane size 17000×21760mmForging abilityUpsetting the largest steel ingot 14tStiring long the largest steel ingot 36tUpsetting the largest steel ingot 30tStiring long the largest steel ingot 50tWeight of the main machine equipment (ton)excluding pump station
