mechanical 3d printer

No computers, no motors, just the power of gravity.

The machine uses a 15kg weight to power the mechanism — it does need to be reset during the print, but that’s a small price to pay for this kind of mechanical automation.

we uses a type of clay in a paste extruder that slowly deposits the material on the build platform. To program the machine, there is a small guiding mechanism that follows the contour of a bent aluminum wire. This allows you to make any number of symmetrical and circular objects.

PLC Based Product Sorting Machine

 

 

Sorting systems are used to bridge between production and packaging machinery. Sorting systems are used to sort items based on various criteria so that they can be packaged accordingly. Manual sorting is a time and effort intensive process. Automatic sorting systems allow for fast and efficient sorting of products. To demonstrate the sorting system we develop a PLC based sorting system project that uses pistons with color sensing system powered by PLC control to achieve this functionality. The system consists of a conveyor belt to carry products from one end to collection baskets. It consists a color sensor to sense the type of products using color sense, the system now utilizes 3 pistons with piping and control valves to control their operations. The system is powered by a PLC to control the sorting system. 3 collection baskets are used to collect samples sorted by the pistons mounted parallel to each one. The PLC coordinates with sensors and piston valves in order to achieve the desired functionality and demonstrate the fully automated product sorting system.

Pneumatic Powered Water Pump

pneumatic-water-pump3

Pneumatic Powered Water Pump:

Water is a basic human necessity and ground water is one of the major sources of it. But pulling out ground water requires a lot of power which is not available everywhere. The most common water suction pump widely used is a manual pump that has a handle which is to be moved in up and down direction in order to suck ground water up and make it available on the surface. So we automate this process using a pneumatic system that does this automatically. Our system uses a pneumatic cylinder along with supporting frame, a manual suction based pump, pipes valves and electronic circuit to control the system. The pneumatic cylinder is connected to the pump using a handle like mechanism that allows for movement of pump head along with the piston movement. We now operate the pneumatic cylinder using a push button that indicates the circuitry to operate the valves which connect the cylinder to a compressor to operate the cylinder and achieve the desired movement. The system now operated the pump head along with the piston movement so as to achieve fully automated water pump using pneumatic power.

AUTOMATIC PNEUMATIC DRILLING MACHINE

AUTOMATIC PNEUMATIC GRINDING MACHINE | MECHANICAL PROJECT
In small-scale industries and automobile maintenance shops, there are frequent needs of tightening and loosening in screws, grinding, boring, grinding machine. Huge and complicated designed parts cannot be machined in ordinary machine. Further for every operation separate machine is required. The increases the initial cost required, large area requirements and large number of machine are required. In a single machine all the above specified operation can be carried out, i.e., after grinding, the drill head is removed from the barrel key and the required tools like grinding wheels, boring tool etc., can be attached, and the operation can be performed. By the application of pneumatic, the pneumatic cylinder with piston which is operated by an air compressor will give the successive action to operate this machine. By this we can achieve our industrial requirements.
INTRODUCTION
The main objective of our project is to perform various machining operations using “Auto feed mechanism” in grinding machine with the help of pneumatic sources. For a developing industry the operation performed and the parts (or) components produced should have it minimum possible production cost, then only industry runs profitability. In small-scale industry and automobile maintenance shops, there are frequent needs of tightening and loosening of screws, grinding, boring, grinding. Further for every operation separate machine is required. This increases the initial cost required, large area requirements and large number of machines is required. In our project the above complicated are rectified.
Mechanization is broadly defined as the replacement of manual effort by mechanical power. Pneumatic is an attractive medium for low cost mechanization particularly for sequential (or) repetitive operations. Many factories and plants already have a compressed air system, which is capable of providing the power (or) energy requirements and the control system (although equally pneumatic control systems may be economic and can be advantageously applied to other forms of power).
The main advantage of an all pneumatic system are usually economic and simplicity the latter reducing maintenance to a low level. It can also have out standing advantages in terms of safety.

WORKING PRINCIPLE
The compressed air from the compressor is used as the force medium for this operation. The pneumatic double acting cylinder used .The air from the compressor enters to the four way junction. From four way junctions one way of air enters to the barrel unit. In side the barrel having vane arrangement is welled. The other way of air enters to the solenoid valve.
The function of solenoid valves all of air correct time interval. From solenoid valve air enters to the pneumatic double acting cylinder through flow control valve. The solenoid valve ON condition, the grinding head is automatically downwards and grinding operation occurs. After some time, the solenoid valve is OFF; the grinding head is automatically released.

Remote Controlled Forklift

 

Here we propose the design and fabrication of a remote controlled mini forklifter . The mini forklifter defines the concepts of using forklifts for weights lifting as well as placement using pulley based mechanism. Our system allows for efficient implementation of this concept. The mini forklift uses pulley and belt arrangement In order to lift loads. It is connected to a powerful 12V motor in order to lift weights and also consists of a counter weight in the back to maintain proper balance while lifting weights. The lifting mechanism is attached onto a 4 wheel drive frame chassis strong to support the frame as well as counterweight. It consists of 4 motors needed to control vehicle movement in all 4 directions. The system uses 2 supporting rods with bearing setup in order to achieve smooth vertical movement of the forklift. Also we use 4 motor drive in order to drive the forklift with efficient strength. We now use an Rf based circuit system in order to run the mini forklift from a distance by receiving wireless control commands by rf remote.

PNEUMATIC SHEET METAL CUTTING

We are using scissors for simple sheet metal cutting. It is a manual method so that sheet metals are to be wasted sometime because of
mistakes happened such as wrong dimensions etc., and also even a simple cutting may take long time.Hydraulic machines are also
available for sheet metal cutting. But this method is used for only heavy metal cutting and its cost is very high.We are using a pneumatic system for sheet metal cutting in a easy way. It is operated by a pneumatic hand lever of two way control valve.Control valve is operated by a compressor.
 COMPONENTS USED
  • Double acting
    cylinder
  • Pneumatic hand
    operated valve
  • High speed steel
    blade

 Working Of Sheet metal Cutter

 

The pneumatic machine includes a table with support arms to hold the sheet, stops or guides to secure the sheet, upper and lower straight – edge blades, a gauging device to precisely position the sheet. The table also includes the two way directional valve. The two way directional valve is connected to the compressor. The compressor has a piston for a movable member. The piston is connected to a crankshaft, which is in turn connected to a prime mover (electricmotor, internal combustion engine). At inlet and outlet ports, valves allow air toenter and exit the chamber. When the compressor is switched ON, the compressed air is flow to inlet of the pneumatic cylinder.
The sheet is placed between the upper and the lower blade. The lower blade remains stationary while the upper blade is forced downward.
The upper blade is slightly offset from the lower blade, approximately 5 – 10% of the sheet thickness. Also the upper blade is usually angled so that the cut progresses from one end to the other, thus reducing the required force.
When the pneumatic hand operated lever is moved forward, the piston starts moving in the forward direction. The upper blade which are then forced against the sheet, cutting the material. When the pneumatic hand operated lever is moved backward, the upper blade will come to the original position (i.e., the upper blade will move upwards).
After the material is cut, adjust the pneumatic hand lever to the mid position (i.e., normal position) and then the compressor is switched
OFF.

APPLICATIONS

Sheet metals are used in
  • Car bodies
  • Airplane wings
  • Medical tables
  • Roofs for buildings (Architectural) and many other things
  • Sheet metal of iron and other materials with high magnetic permeability, also known as laminated steel cores, has applications in transformers and electric machines.
  • Historically, an important use of sheet metal was in plate armor worn by cavalry, and sheet metal continues to have many decorative uses, including in horse tack.
ADVANTAGES
  • Low cost
  • Less consumption of
    time
  • Easy to handle
  • Skilled labor is
    not required
  • Less maintainance
  • High accuracy
  • Good surface finish
  • Less floor space

Pantograph for train engin

The electric transmission system for modern electric rail systems consists of an upper, weight-carrying wire (known as a catenary) from which is suspended a contact wire. The pantograph is spring-loaded and pushes a contact shoe up against the underside of the contact wire to draw the current needed to run the train. The steel rails of the tracks act as the electrical return. As the train moves, the contact shoe slides along the wire and can set up standing waves in the wires which break the contact and degrade current collection. This means that on some systems adjacent pantographs are not permitted.

A Flexity Outlook LRV with its pantograph raised. Note the trolley pole in the rear, which provides compatibility with sections not yet upgraded for pantograph operation.
Pantographs are the successor technology to trolley poles, which were widely used on early streetcar systems. Trolley poles are still used by trolleybuses, whose freedom of movement and need for a two-wire circuit makes pantographs impractical, and some streetcar networks, such as the Toronto streetcar system, which have frequent turns sharp enough to require additional freedom of movement in their current collection to ensure unbroken contact. However, many of these networks, including Toronto’s, are undergoing upgrades to accommodate pantograph operation.

Pantographs with overhead wires are now the dominant form of current collection for modern electric trains because, although more fragile than a third rail system, they allow the use of higher voltages.

Pantographs are typically operated by compressed air from the vehicle’s braking system, either to raise the unit and hold it against the conductor or, when springs are used to effect the extension, to lower it. As a precaution against loss of pressure in the second case, the arm is held in the down position by a catch. For high-voltage systems, the same air supply is used to “blow out” the electric arc when roof-mounted circuit breakers are used

Pneumatic Powered Wall Climbing Robot

 

We here use pneumatic power in order to develop a smart wall climbing robot. The robot makes use of pneumatic power for movement as well as suction in order to cling to the wall. The system is a smart mixture of pneumatic, mechanical and electronic circuitry that allows to achieve this task. The robotic system consists of 2 pneumatic pistons in order to achieve the movement. We make use of valves and drive them electronically in order to achieve the desired movement. Also we make use of suction cups at the end rods in order to achieve vaccum based suction. We use vaccum ejector pistons and drive them through valves to operate the vaccum based system parallel to the pneumatic systems in coordination in order to achieve the desired mechanism. As a result of the coordinated movements of these systems we get a fully function pneumatic based wall climbing robot.

Automatic Tyre Inflation System

Driven by studies that show that a drop in tyre pressure by just a few PSI can result in the reduction of gas mileage, tire life, safety, and vehicle performance, we have developed an automatic, self-inflating tire system that ensures that tyres are properly inflated at all times.  Our design proposes and successfully implements the use of a portable compressor that will supply air to all four tyres via hoses and a rotary joint fixed between the wheel spindle and wheel hub at each wheel. The rotary joints effectively allow air to be channelled to the tyres  without the tangling of hoses. With the recent oil price hikes and growing concern of environmental issues, this system addresses a potential improvement in gas mileage; tyre wear reduction; and an increase in handling and tyre performance in diverse conditions.


Proper Inflation Pressure
The most important factors in tire care are:

  • Proper Vehicle Loading
  • Proper Tire Wear
  • Regular Inspection
  • Good Driving Habits
  • Vehicle Condition
Introduction To Tyre Inflation System:
 
LAYOUT OF TYRE INFLATION SYSTEM:
 
LAYOUT OF TYRE INFLATION SYSTEM:
1.  COMPRESSOR
12V Car Electric Air Compressor Tyre Pump – Tyre Inflator also for Bikes, Cycles, Boats, Inflatable Toys 100% Brand New 12V Air Compressor/Tyre Infiltrator Simply use this for fast & easy inflation of car tires” No strength required for pumping air as it is all electronic & is powered directly from your car battery Perfect for   anyone who wants a ease while inflating a tyre Time saving as compared to mechanical pump .Quick operation, very Compact and easy to store in car dickey SUITABLE For:-  Auto tyres, Car/ bike tyres, rubber rafts balls Inflates car tyres, bicycle tyres, rafts and sports equipment such as Basketball, Soccer fast and      easily.  Also inflates boats, pools, air bed, balloon, etc.
2. SOLENOID VALVES 
2/2 air solenoid valves are direct acting solenoid valves and do not require a minimum operating differential pressure. As shown below when the coil is energized (right diagram), it lifts the solenoid plunger, which normally rests on the valve seat and lifts it to open the main valve orifice. When the coil is de-energized (right diagram), the spring force the plunger return to the valve seat to close the valve orifice.
3. PRESSURE SENSOR 
A pressure sensor measures pressure, typically of gases or liquids. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor usually acts as a transducer; it generates a signal as a function of the pressure imposed. For the purposes of this article, such a signal is electrical.
Pressure sensors are used for control and monitoring in thousands of everyday applications. Pressure sensors can also be used to indirectly measure other variables such as fluid/gas flow, speed, water level, and altitude. Pressure sensors can alternatively be called pressure transducers, pressure transmitters, pressure senders, pressure indicators and piezometers, manometers, among other names.
Pressure sensors can vary drastically in technology, design, performance, application suitability and cost. A conservative estimate would be that there may be over 50 technologies and at least 300 companies making pressure sensors worldwide.
4. ROTARY JOINT
We are designing this device for common passenger vehicles, and the main challenge is the presence of the axle shaft that runs straight into the centre of the wheel forcing us to find an alternative method of routing the air. Our proposed solution to this challenge is to place rotary joint that has one half spinning with the drive axle hub and the other half stationary with the spindle. Within this rotary joint will be an air chamber that will allow air to pass from the stationary half of the joint into the half that is rotating.
5. PRESSURE SWITCH
A pressure switch is a form of switch that makes electrical contact when a certain set pressure has been reached on its input. This is used to provide on/off switching from a pneumatic or hydraulic source. The switch may be designed to make contact either on pressure rise or on pressure fall
6. CAR BATTERY 12 V
An automotive battery is a type of rechargeable battery that supplies electric energy to an automobile. Usually this refers to an SLI battery (starting, lighting, ignition) to power the starter motor, the lights, and the ignition system of a vehicle’s engine.
