What are the advantages of orbital welding machine?

The application range of the orbital welding machine is greatly increased, the structure is simple, the cost is low, the purchase cost of the user can be reduced, the installation operation is convenient, the auxiliary operation time is short, and the work efficiency is high. The support flexible rail includes two parallel rails, and each rail includes a strip substrate.

What are the technical requirements when using the orbital welding machine?

Orbital welding machine shall not be used if the rail has the following conditions:

1. The rail is judged to have internal damage or serious surface injury.

2. The depth of the pit after the top surface of the rail head is damaged and polished:

Weld repair on the line exceeds 8 mm;

Solder repairs over 10 mm outside the line.

3. For scratches, spalling, falling blocks and welding joint wear, low collapse, etc. on the top surface of the rail head, the allowable length of welding repair shall meet the following requirements:

For rail joints (including welded joints) wear and low collapse, the allowable one-time welding repair length is 300 mm, and if the damaged length exceeds 300 mm, it should be divided into two sections for welding repair.

For defects and damages such as scratches, spalling and falling blocks on the top surface of the rail head, the length of one welding repair is allowed to be 200 mm. If the length exceeds 200 mm, it should be divided into two sections for welding repair.

When the rail joints are worn, slumped, scratched and peeled off at the same time, the scratches and peeled off blocks should be dealt with first.

What are the fields of application of orbital welding machines?

At present, the development of railways is mainly in the direction of high-speed passenger cars, subway passenger cars, light rail cars, high-speed heavy-duty trucks, etc. In order to achieve these needs, it is necessary to reduce the weight of trains. A common practice now is to use aluminum alloy materials in the manufacturing process of passenger cars. Because aluminum alloy materials have the characteristics of light weight, corrosion resistance, smooth appearance, complex curved surfaces, and high specific strength, they can effectively reduce the resistance and quality of passenger cars, and increase the overload. In order to effectively improve the processing efficiency of aluminum alloy materials, it is necessary to change the traditional processing method and use the welding technology of the orbital welding machine for processing and manufacturing.

l The plates of the second shell ring are precisely positioned and welded together and fixed to the lower edge of the first ring.

l The plate of the third shell ring is placed outside the second shell ring.

l Lift the entire part of the tank (the top of the two uppermost shell rings).

l Repeat the above operation cycle until the last (bottom) housing ring is completed.

l The entire tank hydraulic jacking system is lowered to the bottom plate and welded to the bottom plate.

l Disassemble the lifting equipment of the tank hydraulic jacking system.

This type of equipment is single-acting two-stage hydraulic cylinder (hydraulic jack), used for vertical take-off and landing work, return need external force or self-weight back, can’t be used for horizontal work.The equipment has strict and compact structure, safe and stable, easy operation, adjustable load, quick installation and high synchronization accuracy.

●The oil box

●The hydraulic system

●The hydraulic cylinder

The oil box

The oil tank is a closed type box with hydraulic oil to provide oil source for the equipment.

1.Liquid level meter shows the oil level and liquid temperature in the box.

2.The air filter has the function of protecting and purifying the gas of hydraulic oil.

3.The lifting lug is used for equipment lifting.

The hydraulic system

Hydraulic system is the power source of the whole hydraulic lifting equipment, first with the motor todrive the piston pump, and then the mechanical energy of the pump into pressure energy, through the pressure valve (relief valve), direction valve (solenoid valve), sent to the actuator (hydraulic cylinder), and finally converted into mechanical energy to drive the load.

1.Protective cover can be disassembled, it mainly protect all parts under the protective cover .

2.Electromagnetic directional valve through the electromagnet with electricity and no electricity to complete the lifting action of the hydraulic cylinder.

3.The relief valve can control the pressure of the system to maintain constant by adjusting the handle of the relief valve, and realize the function of regulating, stabilizing or limiting the pressure.The set of equipment relief valve setting range (0-31.5mpa).　

4.Pressure gauge shows the system pressure value.

5.The high-pressure ball valve makes the hydraulic oil flow or cut-off in the system. The valve mainly plays a safety protection role in this set of equipment.. It prevents the internal leakage of the hydraulic valve from affecting the operation of the hydraulic cylinder's descending equipment. Hydraulic fluid flow or cut-off is controlled by rotating high pressure ball valve handle.

The hydraulic cylinder

1.Hydraulic cylinder is the actuator, rated output force is 250kN.

2.The hydraulic cylinder roof device is the force fulcrum of the piston rod end of the hydraulic Cylinder. In the process of lifting the tank, to prevent the damage of the hydraulic cylinder caused by the bending of the piston rod, or even failure and safety accidents.

3.Adjust the jacking bolt to adjust the gap between the hydraulic cylinder bracket and the tank wall, and tighten the bracket in the process of lifting the tank.

4.The hydraulic cylinder support regulating rod can mainly meet the requirements of resistance to class 5 wind load and tank partial load during the tank lifting process. It can also assist in adjusting the gap between hydraulic cylinder bracket and tank wall when rising circle falls back.

5.The equipment adopts PLC equalization system with automatic and manual modes.And the man-machine control interface is set on the control cabinet.The displacement sensor transmits signals to adjust the equipment at the same height

6.The working principle of the displacement sensor: because the wire rope is wound on a pulley built into the  sensor, and the other end of the sensor has been connected to the mechanical movement, which is equipped with a display, so when the wire rope is pulled, the mechanical movement can be converted into electrical signals, so as to get the required data.　

7.Unidirectional explosion-proof valve is a safety valve that allows the hydraulic cylinder to self-lock.In the process of being lifted or in the process of hanging the tank, the tank will not slide or fall because of the sudden explosion of the high-pressure hose, blurting, sudden power failure, etc.
