Electrical And High Precision Hydraulic Wheel Press

According to the need of railway speeding up & safety, to improve the quality of manufacture inspection & repair of vehicle running gear, the automatic hydraulic wheel press is developed. The machine consists of main press fit framework, position measuring framework, control system. The machine is used to accomplish the press fitting wheel set of railway vehicles. It can fulfill the press fitting double ends of wheel set at the same time, control the position deviation of the wheel set and the inside distance of two wheel sets to attain the range of the criterion. Meanwhile, it produces the data of wheel set press fit. The machine is widely equipped and used in railway vehicle repairing & inspection industry.Specifications:ItemParameterPressure head cylinder max. work pressure    3150KNPressure head cylinder quantity2Pressure head cylinder ram cylinder max. stroke700 mmPressure head cylinder diameterØ360 mmGantry max. pass wheel diameter1050mmMax insert length3000 mmMovable equipment positioning adjustable distance13x200 mmPressure head cylinder plunger rod feeding speed (adjustable)3~30mm/sPressure head cylinder plunger rod push mounting speed (adjustable)0~3mm/sPressure head cylinder plunger rod return speed (adjustable)4~40mm/sTwo centers max. bearing    10000kgElectricity motive small car quantity1setElectricity motive small car max. hold up weight3500kgElectricity motive small car rotation angle180degreeHydraulic system max. working pressure31.5MpaMotor (three phases) voltage380V-50HZBoost voltageDC 24VInstalled gross capacity50KWPressure sensor accuracy≤0.15%FSNoise level when running75dbPressure head measurement inside control precision≤0.5 mmPressure head measurement wheel order difference control precision≤0.5 mmBrake disc  distance control precision≤0.5 mmBrake disc difference control precision≤0.5 mmPressure head repeated positioning accuracy≤+0.025 mmMeasurement accuracy≤+0.03 mmMeasurement error precision (Jump)±0.02 mmMeasuring system precision0.01Pre-press fitting pressure≤50kNOil tank capacity1000LMachine external dimension(L×W×H)6000×2500×2000 mmTag : hydraulic wheel bearing press, hydraulic press machine
