2.1.4 Column
Column material use 45 # forged steel, both ends of procedure has 45 º moment profile thread, close to the table there are column protection covers, guide sleeve material is made by ZQSn6-6-3.Columns are thermal refining,guiding parts quenching treatment at medium frequency,hardness:HRC45-52, oriented part rolling treatment.
Diameter 470mm.
2.1.5 Nuts
45 # forged steel nut material, with hole processing at 45 º thread profile moments, with round columns to match the threads to locking main body
2.2 Oil Cylinder
2.2.1 The master cylinders and return cylinder are plunger type,good quality seals inside fuel tank.Steel cylinder use 35# forged steel piece, plunger rods are 45 # steel forgings,surface quenching treatment, hardness is HRC45~52,circumcircle grinded, guiding sleeve materials is ZQSn6-6-3, one end of the plunger is plug into sliders. Three master cylinder piston diameters are Φ500,Φ880,Φ500. 
2.2.2 Moving working table push to pull cylinder is plunger cylinder, the cylinder material is 45 # forged steel, plunger material is 45 # forged steel, surface quenching treatment,hardness is HRC45~52,cylindrical grinded,one end of plunger rod is connected with moving table,guiding sleeve material is ZQSn6-6-3.
2.3 Moving Working Table
Moving working table is used for easy modes replacement and forging die moved, The material of moving table is ZG270-500 cast steel, table bear the weight of the die sets and working load, and transfer to the body table,under platform are equipped with the guide plate its material is 45 # forged steel, the quenching hardness is HRC42~52, the table moved back and forth is driven by two horizontal cylinders
3,Hydraulic control system
The hydraulic control system consists of cylinder,oil pump motor group,two-way cartridge valve,liquid-filled devices,pipeline,oil tanks and other components.With electric system to control cylinder to drive the slider to move, to complete a variety of process action.
3.1 oil pump motor group
main oil pump motor group: 9. each group consists of 2 sets high-pressure pumps & 1 set motor (200KW)
3.2 two-way cartridge valves
The Hydraulic system control valve block uses two-way cartridge valves, It has the advantages of simple structure,large flow capacity,anti-pollution ability,reliability,fast response,flexible control, etc.
Since the machine has a fast forging process requirements,the master cylinder to the hydraulic control system of relief loop adopted proportional control loop (fast forging valve) to meet the master cylinder pressure relief rapidly, reduce relief shock and noise.
3.3 fuel tank pipeline
The main fuel tank of The hydraulic control system is placed on the ground,fuel tank consists of the oil return tank and the absorption tank equipped with a separate hydraulic oil cooling and filtering system.The fuel tank is steel plate welded,with passive anti-rust treatment. The oil pump motor group is arranged at one side of the tank;some valve blocks and cooling,filtering motor pumps group is placed on the upper plane of the tank. oil pump motor group, the main fuel tank, cabinet separated with the host to form a clean, relatively independent space.
Hydraulic shock and vibration in the press hydraulic system is large,so the hydraulic system piping all joints should be sealed using a special axial flange connection,and set additional shockproof tube cards as requirement,set reasonable piping according to its technical characteristics, reduce energy loss, to prevent leakage.
The oil tank has a level display function if the oil level is too low,must fill the oil tank to the standard level.
3.4 The press filling loop normally adopted closed valve,and its main role is to provide the master cylinder suction oil, when the slider down quickly, due to the negative pressure chamber of the master cylinder, the filling valve opening,a lot of oil suction in the fuel tank, when the slider stops moving, filling valve closed,open filling the spool so that liquid-filled tank to drain the oil from the control slider backhaul.
3.5 The press hydraulic system should have a cooling filter, make sure the oil temperature below 50 ºC.
Hydraulic press oil temperature should be >10 ºC and <60 ºC. When the oil temperature is lower than 10 ºC, the press can not work; only after preheated to 10 ºC, can the press operate. when the oil temperature reaches up to 50 ºC,should open cooling water, cool down the oil. when oil temperature reaches up to 60 ºC should stop working to check,ensure the system working under allowed temperature range.
The hydraulic oil cooling and filtering are equipped with a separate circulation system which starts to circulate automatically after operation.
There is a large-capacity precision filter in the circulation filter system,with the audio alarm warning when the dirt of filter is blocked to indicate maintenance personnel to clean or replace the filter.
4,Electrical control system
   Three-phase five wire system AC power supply voltage is 380V, 50Hz; control circuit is AC 220V; pilot solenoid valve control power is AC 220V.
It is equipped With specialized electrical control cabinets, one main control cabinet, the electrical components used for driving (such as the power switch, air switch,AC contactor, control transformer, leakage protection) are housed inside the cabinet.inside the cabinet the light and the Ventilation facilities (air heat exchanger).
Main control cabinet is installed with the PLC(Germany SIMENSE),The Control panel is also set various buttons and joysticks.Master manipulator cabinet placed on the floor next to the press, easy manipulation and observation.
4.1 The operation of hydraulic can be manual, linkage,exchanged by the switch.
4.1.1 Manual operation: press the manual button there is a corresponding action. If you raise your finger, the action will stop.
4.1.2 Linkage action: action with manipulator.
4.2 Working modes: open die forging process
5,Lubrication System
5.1 It use lubrication pump with electric focus on program-controlled automatic lubrication system that can control the run time and pause time of the pump. 
5.2 Lubricated position are four column guide sleeves of slider, and the friction surfaces between the moving working table and fixed table
6,Safety System
6.1 Each spare parts of the hydraulic system are equipped with hydraulic valve for system overpressure protection.
6.2 There are security platform on the top of the press, fences and up and down escalators, easy to maintain.
