Introduction of electric screw press
Electric screw press is a forging machine with many applications,
having the dual nature of press and forging hammer. Structure is
simple, small volume, short drive system, operation is convenient,
running is safe and low maintenance. Electric screw press is
suitable for all kinds of precision forging, finishing, coining
,embossing and leveling etc process.The strike energy can be set
accurately according to the die precision, can reduce the time of
mechanical stress and the amount off time the hot work piece is in
contact with the die, thus prolonging the die life.The frame is
rigid, good guide ability, strong bias load resisting ability, can
be used in multi-die forging, it is a energy-saving and
environmental protection forging press.

Electric screw press working principle
Slide moves up & down driven by motor through pinion, gearwheel
and screw, gearwheel has enough inertia act as flywheel. After
input start signal, motor from stationary state drives slide
accelerate downwards through pinion and gearwheel, motor stop
accelerating after reaching required speed by pre-set blow energy,
Kinetic energy stored by gearwheel works, e.g. forming work. At the
same time, motor immediately drives gearwheel to reversal rotation,
when reaches a certain point, motor will start to brake, drives
slide back to pre-set position. Since brake is by motor when slide
is in return stroke, mechanical brake only works when slide is
close to up dead point, brake material is not easy to wear, no need
Futures of screw press
- Using AC frequency conversion direct torque control technology
servo driving system , frequency converter is ABB brand, with
- The striking energy is precisely setting with high deforming
precision, suitable for various nonferrous metal precision forging
- Easy programming for automation.
- Bottom point is not fixed, not necessary to adjust the die height,
without forging dies stick together phenomenon.
- Due to the striking energy precise control, the forging die life is
- The main frame structure is simple, easy operating and maintenance.
- The moving parts with low noise, low vibration, satisfy
environmental protection, and reduce the foundation building costs.
- Relatively short stroke, the energy output is stable, and
repeatability precision is high .
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
Screw is CrMoV high alloy forging, thread type has good fatigue
resistance, no self-lock, stable installation, short screw,
increased press rigidity.
Made of bronze material, installed inside slide, has good abrasive
resistance and emergency sliding performance.
The slide block is using high class steel casting with full aging
treatment to relief stress.
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.
The brake directly effected with gear make it braking at any
position, the brake is closed through spring force, and opening is
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
Automation electric screw press forging line
The electric screw press as the key equipment, Anyang forging press
company can supply the forging production line for the customers,
