Bending Machine Valve Group

The bending machine valve group is a key component used to control the hydraulic system in the bending machine (also known as CNC bending machine, mechanical bending machine). Its main function is to accurately control the movement of the bending machine by adjusting the flow and pressure of the oil, ensuring that the equipment works safely and stably during the bending process.
The bending machine valve group is usually composed of multiple different valve bodies, control elements, sensors and interfaces. According to different needs, it can have multiple functions, such as hydraulic control, pressure regulation, flow regulation, direction control, etc. Its quality and performance directly affect the working efficiency and operating accuracy of the bending machine.

Main Functions and Features
Hydraulic system control: The valve group controls the working state of the bending machine, such as upper die lifting, workbench movement, etc., by adjusting the flow, pressure and direction of the hydraulic oil.
High-precision control: The bending machine valve group usually adopts high-precision pressure regulating valves and flow control valves to ensure accurate control of the pressure and flow of the hydraulic system, so that the bending machine can achieve higher precision and stability in operation.
Multi-way control: The valve group generally includes multiple valves, such as pressure valves, directional valves, flow valves, etc., which can coordinate and control the sequence and speed of different hydraulic actions to achieve complex operation requirements.
Safety protection function: In the case of high pressure or overload of the hydraulic system, the valve group is often equipped with a safety valve and a relief valve to automatically release excess pressure, prevent system damage, and ensure equipment safety.
Energy saving and effective: Modern bending machine valve groups often adopt energy-saving designs, such as leak-free valves, load sensing systems, etc., to reduce energy consumption and improve system efficiency.
Easy to maintain and replace: Since the valve group is the core component of the hydraulic system, many valve group designs focus on modularization, which is easy to repair and replace, and reduces the frequency of failures.

Common Types
Direction control valve: A valve used to control the flow direction of hydraulic oil, adjust the direction of oil flow to control the various actions of the bending machine, such as the lifting and lowering of the workbench, the adjustment of the bending angle, etc.
Pressure control valve: Used to set the pressure value of the hydraulic system to ensure that the bending machine does not exceed the safe pressure range during operation and avoid overload.
Flow control valve: Controls the flow rate of hydraulic oil, affecting the speed and accuracy of equipment movement.
Relief valve: plays a role in pressure overload protection and prevents damage to the hydraulic system.

Application Areas:
1. Sheet metal processing and manufacturing
Sheet metal processing is one of the main application areas of bending machines. The bending machine valve group controls the movement of the upper and lower dies by adjusting the hydraulic system, so that metal sheets can be bent at different angles and lengths. Sheet metal processing often involves metal materials such as steel, stainless steel, and aluminum alloy. The bending of these materials requires accurate control, and the high-precision control function of the bending machine valve group can ensure the high quality and high precision of the product. Common applications include the production of chassis, shells, sheet metal structural parts, etc.
2. Automobile manufacturing
In the automobile manufacturing industry, the bending machine valve group is used to produce body parts, chassis frames, doors, roof supports and other parts. With the development of the automobile industry, automobiles have higher and higher requirements for high-precision and efficient bending, and the role of the bending machine valve group is particularly important. By accurately controlling the hydraulic system of the bending machine, the bending machine valve group can ensure the dimensional accuracy and appearance quality of the body parts, help improve production efficiency and reduce material waste.
3. Aerospace
The aerospace industry has strict requirements for bending machines. It not only requires high-precision bending capabilities, but also requires bending control of lightweight and high-strength materials such as aluminum alloys and titanium alloys. Bending machine valve groups are widely used in the aerospace field to help manufacture high-precision parts such as aircraft structural components, wing frames, and cabins. The bending machine valve group can ensure the stability of the hydraulic system, so that the bending machine can operate stably under requirements and ensure manufacturing accuracy.
4. Metal processing and manufacturing
The metal processing industry includes the processing of a variety of metal materials from steel, aluminum alloys, copper alloys to stainless steel. The stability and accuracy of the hydraulic system are crucial during the bending, forming and processing of these materials. The bending machine valve group can effectively adjust the pressure, flow and direction of the hydraulic system to ensure the bending accuracy and consistency of metal sheets during the production process. Common metal processing industry applications include pipeline manufacturing, building steel structures, and the production of metal shell parts.
5. Construction and decoration industry
The application of bending machine valve groups in the construction and decoration industry is also becoming more and more extensive. In the production process of building metal structures and decorative materials, bending machines are used to process materials such as aluminum alloys, steel, and stainless steel. The bending machine valve group helps control the bending angle and shape to ensure that the bending effect of the material meets the design requirements. Components such as door and window frames, stair handrails, and building support frames in the construction industry often need to rely on bending machines for processing.
6. Shipbuilding
The shipbuilding industry also needs to use bending machines on a large scale to form metal sheets. In shipbuilding, the bending machine valve group is mainly used to process metal parts of the hull, including the bending and forming of steel plates.
7. Home Appliance and Electronic Product Manufacturing
The application of bending machine valve groups in the home appliance industry is also common, such as the production of air conditioner shells, refrigerator shells, washing machine parts, etc. These home appliances usually need to be processed by bending machines to process metal shells. The bending machine valve group ensures control during the processing and helps produce home appliances that meet standards and specifications.
8. Heavy Machinery and Equipment Manufacturing
In heavy machinery manufacturing, bending machine valve groups are used to process large metal structures, such as machinery shells, equipment brackets, etc. These structural parts require high strength and high precision. The bending machine valve group helps manufacturers ensure the dimensional accuracy and surface quality of the bent parts through hydraulic control, ensuring the stability and durability of the equipment.
