The plate rolling machine hydraulic cylinder is an important part of bending machine. Its main function is to provide power and control the movement of the bending roller.

 

1. Working principle of hydraulic cylinder of plate rolling machine


Plate Bending Roller Machine Hydraulic


Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has a simple structure and reliable operation.

 

When used to complete reciprocating motion, it can avoid the deceleration device, has no transmission gap, and has smooth movement. It is widely used in various mechanical hydraulic systems.

 

Hydraulic transmission principle:

Oil is used as the working medium, and power is transmitted through the pressure inside the oil.

 

- Power section

Convert the mechanical energy of the prime mover into the pressure energy (potential energy) of the oil. For example: various hydraulic pumps.

 

- Execution part

The oil pressure energy input by the rolling machine hydraulic pump is converted into mechanical energy that drives the working mechanism. For example: various hydraulic cylinders and hydraulic motors.



- Control section

Used to control and regulate the pressure, flow and flow direction of oil. For example: various pressure control valves, flow control valves.

 

- Auxiliary part

Connect the first three parts together to form a system, which plays the roles of oil storage, filtration, measurement and sealing. For example: soft and hard pipelines, joints, fuel tanks, oil filters, accumulators, seals and display instruments, etc.

 

During use, the rolling machine hydraulic cylinder may need to be disassembled due to various reasons. The following is an expanded explanation from the disassembly steps, precautions and common problems of the hydraulic cylinder.

 

2. Steps to disassemble the rolling machine hydraulic cylinder

1) Disconnect the hydraulic system

Before disassembling the hydraulic cylinder, we first need to shut down the hydraulic system and disconnect the hydraulic cylinder from the hydraulic system. Avoid the hydraulic cylinder being affected by the hydraulic system during disassembly.

 

2) Clean the hydraulic cylinder

Before disassembling the hydraulic cylinder, we should first clean the dirt on its surface. To avoid bringing dirt into the hydraulic cylinder during disassembly.

 

3) Remove the connecting parts

According to the structure and connection method of the hydraulic cylinder, remove the connections between the hydraulic cylinder and other components, such as bolts, bearings, etc.

 

4) Remove the seal

There are usually multiple seals inside the hydraulic cylinder, such as piston seals, rod seals, etc. When disassembling the hydraulic cylinder, these seals need to be disassembled one by one. And pay attention to record their location and order so that they can be installed correctly during subsequent installations.

 

5) Remove the piston rod

The piston rod of the hydraulic cylinder is connected to the piston. When disassembling, we need to remove the piston rod from the hydraulic cylinder. During the disassembly process, care should be taken to avoid scratches or damage to the piston rod and the inner wall of the hydraulic cylinder.

 

6) Remove the piston

When disassembling the rolling machine hydraulic cylinder, we need to remove the piston from the hydraulic cylinder. During the disassembly process, we should pay attention to avoid scratches or damage to the inner wall of the piston and hydraulic cylinder.

 

7) Inspection and cleaning

After disassembling the hydraulic cylinder, we should inspect and clean it. Check whether there are any damaged or worn parts inside the hydraulic cylinder, and replace them in time if necessary. When cleaning the hydraulic cylinder, we should use clean solvent or hydraulic oil to thoroughly clean the inside.

 

3. Precautions for disassembling the hydraulic cylinder of the plate bending machine


When disassembling the hydraulic cylinder of the plate bending machine, you need to pay attention to the following points:

1) Safety first

Before disassembling the hydraulic cylinder, we should first ensure that the plate bending machine is in a stopped state and take appropriate safety measures. For example, cut off the power supply, lock the switch, etc. to avoid accidental injury.

 

2) Record details

During the process of disassembling the hydraulic cylinder, we should pay attention to record the details of each step, including the disassembly sequence, disassembly tools, disassembly position, etc., for reference during subsequent installation.

 

3) Attention to protection

When disassembling a hydraulic cylinder, we should pay attention to protecting the surface and internal components of the hydraulic cylinder to avoid scratches or damage.

 

4) Attention to installation sequence

After disassembling the roller machine hydraulic cylinder, we need to install it in reverse order to ensure that each component is installed correctly. And be careful to use the appropriate torque for tightening.

 

4. Summary of FAQs



- What should do if encounter difficulties when disassembling the rolling machine hydraulic cylinder?

If you encounter difficulties during the disassembly of a hydraulic cylinder, you can refer to the relevant disassembly manual or seek professional advice. Avoid using excessive force or improper methods that may cause damage.

 

- How to maintain the hydraulic cylinder after disassembling it?

After disassembling the bending roller hydraulic cylinder, we should clean and maintain it. When cleaning, appropriate solvent or hydraulic oil should be used to thoroughly clean the inside, and attention should be paid to protecting the surface and internal parts of the hydraulic cylinder.

 

During maintenance, the hydraulic oil should be replaced regularly, and the seals and parts of the hydraulic cylinder should be checked for damage or wear. Replace in time if necessary.
