About Electrically operated screw press pickaxes electrically operated screw forging press

Advantages of Anyang screw press design

Our electric screw press adopts gear drive mode, features of this drive mode are: adopts special motor, high RPM, less torque, different tonnage press with different power special motor, easy to replace when motor breaks down, easy & simple maintenance, motor performance is not affected when screw guide bushing is worn out., efficiency of electric screw press improved a lot with continuous improvements & innovations in many years, this gradually established our leading position in electric screw press market.

Screw structure:
Screw is CrMoV high alloy forging, thread type has good fatigue resistance, no self-lock, stable installation, short screw, increased press rigidity.

Nut:
Made of bronze material, installed inside slide, has good abrasive resistance and emergency sliding performance.

Slide Block:

The slide block is using high class steel casting with full aging treatment to relief stress.

Guiding system:

The guiding system has 45 degree arrangement with the slide block surface, to keep constant clearance and not affected by the thermal expansion. The guiding set is using bronze and steel. The guide rail with nitrogen treatment, the guide plate can be adjusted from each direction to ensure the smallest guide rail clearance. The slide block guiding length and rigidity etc. can ensure to produce the high quality products with long die life.

Brake apparatus:

The brake directly effected with gear make it braking at any position, the brake is closed through spring force, and opening is pneumaticly controlled.

Driving unit:

The precision screw drive is driven by squirrel-cage three phase positive and reverse asynchronous motor, this kind of driving unit with low maintenance and high reliability features.

Lubricating oil circulation:

There is a monitoring lubricating oil circulating system to lubricate the spiral thrust bearing constantly. The guide rail lubricating features will sustain in numbers of circulation.

Combined type press frame:

There are numbers of advantages of the combined type frame, to eliminate the notch stress centralization between the working table and columns, between the crossbeam and columns. The large size of forging press can be dismantled and transported by several pieces. The frame adopts pre-stressed connection with high rigidity, under same tensile stress, the extensibility is only 20% of the unibody designed frame.
