The composition of the hydraulic group to the roller frame:

1. Trolley traveling mechanism: The trolley traveling mechanism is a mobile structure that supports the entire roller frame. It usually includes wheels, axles and a manual operating system. This mechanism allows the roller frame to move freely within the work area, making it easy to move the equipment to the desired location.

2. Roller frame: The roller frame is the main part that supports and rotates the workpiece. It usually includes components such as shafts, rollers, and support structures. The design of the roller allows the workpiece to rotate during assembly and welding, ensuring uniformity of the weld.

3. Hydraulic system: The hydraulic system is a key component of the drive unit and roller frame. It includes hydraulic cylinders, hydraulic motors, fuel tanks, pumps, etc. Through the hydraulic system, the up and down movement of the rollers, adjustment of the pressing force, etc. can be controlled to ensure the stability and accuracy of the assembly operation.

4. Control system: The control system is responsible for monitoring and adjusting the hydraulic group to each part of the roller frame. It may include buttons, switches, LCD screens, etc., for the operator to control and monitor the equipment. Some advanced equipment may also have automated control systems that can realize some automated pairing operations.

Characteristics of the pressure group on the roller frame:

1. Precision control of the hydraulic system: The hydraulic group uses a hydraulic system for the roller frame to control the movement of the rollers. Through components such as hydraulic cylinders and hydraulic motors, functions such as moving the rollers up and down and adjusting the group pressure can be realized. This hydraulic control allows the pairing operation to be more precise and controllable.

2. Automatic centering function: Hydraulic alignment roller frames usually have an automatic centering function, which can detect and adjust the position of the workpiece to ensure that the workpiece can be correctly and accurately aligned during the assembly operation. This feature reduces the operator's burden and improves operation accuracy.

3. Flexible adjustment of roller position: The position and spacing of the rollers on the roller frame can usually be adjusted hydraulically. This allows the equipment to adapt to workpieces of different diameters and lengths, improving versatility and adaptability. The operator can adjust the position of the roller according to the requirements of the specific workpiece to meet the needs of different processes.

4. Safety design: Hydraulic group roller frames are usually equipped with safety devices, such as emergency stop buttons, overload protection, etc., to ensure safety during operation. These safety devices help reduce the potential risk of accidents and protect operators and equipment.

5. Suitable for large workpieces: Due to its hydraulic control and structural design, the hydraulic assembly roller frame is particularly suitable for assembling large workpieces, such as pressure vessels, storage tanks, pipelines, etc. Its strong load-bearing capacity and stability make it an ideal device for handling large-scale industrial projects.
