Vane air motor description:
With compressed air as actuating medium, vane air motor makes use of the expansion of compressed gases; convert the pressure energy into mechanical energy. Air motor has simple structure, small size, light weight, high horsepower, and easy to be operated and maintained. It also has the feature of proof water, fire, moisture and explosion. It can work in humid, high temperatures, high dust and other proof working environment. Besides mine, rock drilling and loading, it was also widely used for ships, metallurgical, chemical, petrochemical, volatile atmosphere, paper and other industries.
Vane air motor features:
1. Great for harsh environments: it does not build up heat or sparks make air motors ideal for use in flammable or explosive applications.
2. Intrinsically safe in hazardous environment, can work in humid, high temperatures, high dust and other proof working environment, for example: mines , petrochemical , volatile atmosphere, flammable or explosive applications.
3. These air motors can be coupled with gearboxes to increase torque and reduce speed.
4. Simple structure, small size, light weight, high horsepower, and easy to be operated and maintained.
5. Air motors can easily operate under conditions which are unfavorable electric, hydraulic, stepper and servo motors.
Applications:
Mixing equipment, conveyor drives, pump drives, food packaging, pharmaceutical packaging,
Winches and hoist, hose reels, fiberglass choppers, tension devices, turntables, oil and gas
Industry for air winches and mining equipment
Working principle:
With the compressed air, the pressure energy is converted into mechanical energy by the piston air motor.
After the compressed air enters into the inlet of the air motor, the air distributing system (valve core and valve bush) distributes the compressed air in sequence into the air cylinders. The compressed air in the said cylinders is expanded to push the piston reciprocating moving, then to drive the connecting rod and crank to revolve.
Features:
Compact and powerful
Easily operate and low maintenance
Reliable and stable run under inflammable, explosive, outdoor, wet, damp and other extremely conditions
Overload protection function, automatically reduce to a lower speed until overload relieved and restart
Speedless control regulates the input air volume to adjust the rotary speed and power.
The air motor can be started, stopped and converted direction frequently.
Self-cooling of air motor, thus the air motor can work with wide temperature rang from 0-150 celsius(or 0-302f).
When air motor works, no sparks or leaking oil occurred, thus the air motor can work run under inflammable, explosive circumstance.
Application:
Air motors are widely used in different industry fields, especially in extreme circumstance, where electric motors or other engines can not be used. The typical industrial applications:
Pneumatic mixers
Pneumatic conveyer
Drill rig
Gunite machine
Pneumatic winch

Main application and features
Press brake is kind of machine used in cold-forming metal sheet or strip into a desired cross section or structural shape. Normally, with one bending, metal sheet could be bend into cross section. With several bending, it can get complex sectional shaps. It is wildly used in machinery, light industry, automobile, shipbuilding, container, crane, building construction, metal construction, lamppost and electrical post, and so on.
Totally european design, streamlined looking
-frame consists of right and left wall boards, working table, oil tank, slot steel and etc. The stress of the welded parts can be eliminated by vibration. The machine enjoys high accuracy and high strength and can be transported easily
-welded structure: the stress of the welded parts can be eliminated by vibration; so this forging press gives high accuracy.
- high accuracy, high efficiency, simple and convenient operation, good performance, favorable price and best service.
Reliable hydraulic system
- adopt integrated hydraulic control system, more reliable and easy for maintenance. The hydraulic system consists of motor, oil pump and valve groups and it is installed at the top of the oil tank.
- every complete working cycle can be achieved through the control of hydraulic valve.
-extremely reliable and precise rexroth or vickers or bosch valves are used for the regulating circuit.
-there is also a low sound lever pump and a large tank with oil level and temperature gauge on the oil filter.
- overload overflow protection is outfitted to hydraulic system, which can assure no leakage, and the oil level can be read and seen directly.
Main machine
1.Frame structure
Full steel structure, stress released, with accuracy well kept.
Main component is designed and Finite Element Analyzed through ANSYS software.
Main frame composes of uprights, working table, holding-down beam and oil tank.
Ball transporter and supporting bar and squaring arm are fixed on working table.
2.Upper blade beam and blades
Guillotine type blade beam, with rake angle adjustable
The rake angle could be motorized adjusted by press button according to material and thickness.
When shearing thin thickness sheet, the rake angle could be reduced, thus the distortion of the product and the burr could be minimized.
Exchangeable Rectangle blade, with 4 cutting edges available.
Blade material 6CrW2Si with hardness HRC53-60, with quality shearing result and long life.
3. Shearing length/stroke adjustment
The shearing stroke could be adjusted through knob to the length of the product. Thus efficiency could be improved.
4. Cutting beam guiding and blade clearance
The cutting beam is guided between roller guides. At the rear of the cutting beam there are two sets of upper and lower roller guides located at each end of the beam.
Two spring-loaded rollers located at the front of the shear apply pressure to the cutting beam, forcing it against the back roller guides.
The bearings of the upper roller guides at the back of the cutting beam are mounted on an eccentric shaft. Rotating this shaft causes the cutting beam to tilt, thus providing proper blade clearance to the shearing blades.
The upper cutting beam inclined forward, with high section-cutting quality on the product.
The blades clearance could be adjusted manually through hand-wheel according to material and thickness.
Since the blade clearance is 0.1 to 2.5 mm, the shear can cut thickness 1mm to 40mm mild steel.
5. Hydraulic system
LVD special hydraulic unit for heavy type shear is adopted.
Hydraulic control components is from VICKERS,USA (or REXROTH, Germany)
With in-series cylinders to achieve good synchronization.
The sheet is pressed by hold-down before shearing and during shearing for safety and reliability.
One-time machining on CNC lathe for cylinder body and piston rod. Horning for inner surface of cylinder, vibration super-fine machining on the outer surface of the piston rod.
Oil seals from NOK, Japan (or Merkel, Germany) with low wear and tear, no oil leakage.
High-pressure internal gear pump, with reliability and low noise.
Over-load protection for hydraulic system
