Anyang Forging Press Since 1956
China National Forging Hammer Standard Drafter
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 structure diagram
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 frequent change.
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 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 pneumaticly controlled.
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.
The electric screw press as the key equipment, Anyang forging press company can supply the forging production line for the customers, include cutting equipment, heating equipment, preform forging equipment, forging robots, Trimming equipment and integrated system etc.
Electric screw press can forge Claw Pole, connecting rod, form machinery, spherical hinge, Auto parts forging, control arm, riggings etc steel forgings. also can forge Brass, Aluminum etc Non-ferrous metals.
