Product inroduce:
   The advantage of static pressure type electric screw press is its static pressure screw-nuts and the static pressure bearing.And all these parts are designed to be in a closed system.When screw rotates, the nut will drive the slide block to move up and down. A forced lubricating system will feed the lubricate oil into the closed screw-not system through special pipeline,and form an oil screen between each touching parts to reduce the parts friction when press works.The lubricate oil coming out form the closed screw-nut system will be pumped back to the filter system to be filtered,and then will be injected into screw-nut system again. This whole system greatly reduces the wear and tear of the parts and extends the machine service life by two times then common type press. Additionally, this type of static
type electric screw press is nice in appearance, cost-efficient in power consumption and stable in performance.

Product feature:
Servo motor drive system:
1. Small start-up current: little impact on power grid.
2. Motor starts when press is punching and stops when feeding material,picking out bricks,and cleaning mould. Energy-saving high to 55%.
3. High control precision: speed error is only 0.0001/r.
4. Stable running:  no vibration and high torque when runs with low speed.
5. Quick response: very short time from static to rated speed, able to adjust speed freely between high speed to low speed within one stroke. Excellent effect of even hammer strike.
6. Speed overload function, achieves 2-3 times of rated speed.

Touch screen parameter setting system:
1. According to technology demands for different bricks, user can set the strike times, strike strength, and strike speed digitally. Able to achieve the effect of gently press for air-released, strike from gentle to heavy, the whole process of brick producing sequencing, reduce human factor to improve product quality.
2. Touch screen can real-time display the working status, monitor the producing process, detect and report the failure automatically.
3. Able to set password to protect production safety.
4. Touch screen has operation instruction and guideline.

Full automatic lubrication system:
1. Main engine adopts program controlled thin oil lubrication system, screw, nut and guide rail adopt program controlled grease lubrication system.
2. Oil shortage alarm function ensures equipment run healthily.
3. No need of maintenance, improves the service life of equipment and reduces the maintenance cost.

Multiple safety protection system:
1. Motor brake: through servo motor’s zero speed and torque to produce brake.
2. Mechanical brake: cylinder pushes friction plate to produce mechanical friction brake on the flywheel.  
3. Emergency stop button: during working, it is able to press the emergency stop button at any time to make the slider back to TDC(top dead center) quickly.
4. Power loss protection: when power supply is abnormal, slider will stop immediately.
5. Optional equipment: can adopt demoulding outside the machine and add infrared raster.   

One button operating system:
1. Only need to press the start button to finish the whole working process.
2. Fool-style operation, no need of professional press machine operator.
3. Laborsaving, only need 2 people to finish all the procedure of weighing, material feeding, moulding and brick discharging.
4. 3 types of striking technology: press button to match die, semi-auto strike and full-auto strike.
5. Emergency stop button can realize the emergency stop at any time.
