Four Columns Hydraulic Press,used electric hydraulic press

Main body The main body is organized by press crown, beam, working table, uprights, locknuts and adjusting nut. There are guide sleeve to be employed inside the beam. The precise can be adjusted through adjusting the locknuts and adjusting nuts that tightened on the press crown. There are T-type channels on the beam and working table, so that the tools can be equipped convenience Main cylinder Main cylinder is fixed on the press crown Stroke limited equipment The stroke limited equipment is installed on the left side of the machine, it can control the stroke distance, the beam stroke distance can be adjusted by adjusting the distance of the travel switch. Hydraulic Station It’s including oil container, axial plunger pump, motor, two-ways cartridge valve, oil cleaner, air cleaner. Press gauge and overflow valve are equipped on the oil container so that the operator can observe the hydraulic pressure and adjust the oil pressure easily. Cartridge valve equipped for hydraulic system, reliable, durable and less hydraulic shock. The machine is equipped the hydraulic supporting safety loop to keep the security when the beam is out of control. Water cooler is employed to cool the temperature of the hydraulic oil to keep the oil temperature doesn’t exceed 55°C. When the oil temperature is over 45°C, connect the water cooler system, the system will give a alarm when the oil temperature is over 50°C; When the oil temperature reach 55 °C, the control system will cut off the power to keep the oil temperature not over 55°C. Electric control system The electric cabinet is separate from the main structure, this machine is supplied with the moving operating panel so that the operator can operate machine at a big area range. Power: AC380V,50 Hz Operating system 1   Inch action Mainly used for adjust the machine and change tools, 2   Manual 3    Semi-automatic: press the respectively buttons to finish one working circle 3.1          Without knock out techniques, Beam down in no-load mode →beam switch to work mode by proximity switch → beam down in work mode till desired force achieved→ start time relay when desired force achieved → beam all way up after time on time relay runs out 3.2          With knock out techniques Beam down in no-load mode →beam switch to work mode by proximity switch →beam down in work mode till desired force achieved→ start time relay when desired force achieved → beam all way up after time on time relay runs out →knock out cylinder at upper limit start time relay→ knock out cylinder return after time on time relay runs out 3.3  Drawing techniques Beam down in no-load mode →beam switch to work mode by proximity switch → beam down in work mode till desired force achieved→ start time relay when desired force achieved → beam all way up after time on time relay runs out   4.Working environment  Temperature: 0°C - 40°C2.     Humidity: relative humidity is under 90%.3.     Voltage: 380V(-15%,+15%),3P,50Hz   Security protection Beam upper limited is protected by the light curter With “PAUSE” & “EMERGENCY STOP” button.
