J58K series CNC screw press double bottom pan welding titanium alloy lamina connecting rod spherical hinge claw pole

Product Description

 

J58K series CNC screw press is developed by us and research institutions inland on the basis of assimilating advanced technologies of electric screw press and clutch screw press from abroad.This machinery is a kind of equipment with excellent technology applicability,energy-saving and environmental protection,higher automation level.It is not only used in hot forging but also used in finish forge and finishing.Meanwhile it is used in atainless steel double bottom pan welding technology and the finish forging of titanium alloy lamina and other laminas.It is an indispensable equipment in modern forging field.

 

 The machine has the characteristics of strong anti-bias ability, low mold stress, long life, and high precision forming of forgings. It is superior to traditional screw presses in terms of energy saving and precise control of strike force, and is suitable for die forging, precision forging, correction, bending, embossing and other processes. It is an ideal precision forging equipment for industries such as trains, automobiles, tractors, ships, aviation, hardware tools, medical equipment, tableware, and refractory materials.

 

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 frequent change.

 

Futures of screw press

 

Various frame types / customized

 

Flywheel adopts friction overload protection / safe and reliable

 

Higher rigidity / reliable

 

Advanced intelligent control system

 

High precision / high stability of control and transmission

 

Optional / multi device system

 

 

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.
