Double head pipe bending machine Structure and Working Principle
Structure: Generally, it consists of the machine body, power system, transmission system, bending die, control system and other parts. The machine body is the supporting structure of the machine, usually made of high-strength cast iron or steel structure to ensure the stability and rigidity of the machine during operation. The power system mainly includes the motor and the hydraulic pump station, which provide power for the pipe bending machine. The transmission system transmits the power to the bending die to realize the bending action of the pipe. The bending die is the component that directly contacts the pipe and causes it to bend and deform. It usually consists of multiple modules and can be replaced according to different pipe diameters and bending radii. The control system is used to control the operating parameters of the machine, such as bending angle, speed, pressure, etc., to ensure the quality of pipe bending.
Working Principle: The motor drives the hydraulic pump station, and the pressurized hydraulic oil is delivered to each hydraulic cylinder. When a pipe bending operation is required, the hydraulic cylinder pushes the bending die to move, applying an external force to the pipe, causing it to bend and deform under the action of the die. By precisely controlling the stroke and pressure of the hydraulic cylinder through the control system, the bending angle and radius of the pipe can be accurately controlled. At the same time, some advanced double-head pipe bending machines are also equipped with automatic feeding and unloading devices, which can realize the automatic feeding, positioning and unloading of pipes, improving production efficiency.
Features
High Efficiency: The double-head design enables the machine to bend two pipes simultaneously, or to bend two different parts on the same pipe at the same time, greatly improving production efficiency. For example, in the production of automobile exhaust pipes, the traditional single-head pipe bending machine needs multiple clamping and processing operations to complete the bending of one exhaust pipe, while the double-head pipe bending machine can complete the processing of multiple bending parts in one clamping, reducing processing time and labor costs.
High Precision: By adopting advanced numerical control systems and precision transmission components, it can accurately control the bending angle, radius and position accuracy of the pipe. Some high-end double-head pipe bending machines can control the bending angle error within ±0.5° and the radius error within ±0.1mm, which can meet the requirements of various high-precision pipe bending. For example, in the aerospace field, the bending accuracy requirements for key components such as aircraft engine oil pipes are extremely high. The double-head pipe bending machine can ensure the quality and reliability of these components with its high-precision processing ability.
Flexibility: It can adapt to the bending processing of pipes with different diameters, wall thicknesses and materials by replacing different bending dies and adjusting the machine parameters. From thin-walled copper pipes with a diameter of a few millimeters to thick-walled steel pipes with a diameter of several tens of millimeters, they can all be bent on the double-head pipe bending machine. Moreover, the parameter adjustment of the machine is convenient and quick. The operator can complete the parameter setting and die replacement in a short time, realizing the rapid switching production of pipes of different specifications and meeting the diversified production needs.
Stability: The machine body has a solid structure and the hydraulic system is stable, which can maintain good performance and processing quality during long-term continuous operation. High-quality double-head pipe bending machines are carefully designed and manufactured, using high-strength materials and advanced manufacturing processes. The machine body has sufficient rigidity and stability and can withstand large bending forces without deformation. At the same time, the hydraulic system has been strictly tested and optimized, with good sealing performance and reliability, reducing the occurrence of machine failures and unstable processing quality caused by problems such as hydraulic leakage.
Classification
Classification by Control Mode
Manual Double-head Pipe Bending Machine: This type of pipe bending machine mainly controls parameters such as the bending angle and bending speed through manual operation. The operator needs to use some simple tools, such as wrenches and handles, to adjust the position of the die and apply the bending force. The manual double-head pipe bending machine is suitable for the bending processing of some small batches of pipes with simple shapes. Its advantages are simple operation and low cost, but the processing accuracy and efficiency are relatively low.
Semi-automatic Double-head Pipe Bending Machine: On the basis of the manual pipe bending machine, some semi-automatic control functions are added, such as using a motor drive to realize the rotation of the die and the feeding of the pipe, and using an electrical control system to control parameters such as the bending angle and speed. The operator only needs to set the relevant parameters on the operation panel, and the machine can carry out the pipe bending processing according to the set program. The processing accuracy and efficiency of the semi-automatic double-head pipe bending machine are significantly higher than those of the manual pipe bending machine, and it is suitable for the bending processing of some medium batches of pipes with relatively low accuracy requirements.
Fully Automatic Double-head Pipe Bending Machine: It adopts an advanced numerical control system (CNC) to control the entire pipe bending process, and can realize a series of operations such as automatic feeding, positioning, bending processing and unloading of pipes. The operator only needs to input parameters such as the specifications, bending angle and radius of the pipe on the operation interface of the numerical control system, and the machine can automatically complete the entire pipe bending process without manual intervention. The fully automatic double-head pipe bending machine has the advantages of high processing accuracy, high production efficiency and good repeatability, and is suitable for large-scale and high-precision pipe bending processing, which is widely used in industries such as automobiles, aerospace and electronics.
Classification by Drive Mode
Hydraulic-driven Double-head Pipe Bending Machine: It uses the pressure of hydraulic oil to drive the bending die to move, realizing the bending processing of pipes. Hydraulic drive has the advantages of large power, stable transmission and high control precision, and can adapt to the bending processing of various pipes with different materials and specifications. At the same time, the hydraulic system can also meet different bending force and speed requirements by setting different pressures and flow rates, and has strong flexibility and adaptability. Therefore, the hydraulic-driven double-head pipe bending machine is currently the most widely used type of pipe bending machine.
Mechanically-driven Double-head Pipe Bending Machine: It drives the bending die to move through mechanical transmission components such as motors, reducers, gears and chains. The advantages of mechanical drive are simple structure, convenient maintenance and low cost, but due to its relatively low transmission efficiency and control precision, it is generally suitable for occasions where the requirements for bending precision are not high and the pipe specifications are small.
Pneumatic-driven Double-head Pipe Bending Machine: It uses compressed air as the power source and drives the bending die to move through cylinders and pneumatic components. Pneumatic drive has the advantages of fast response speed and cleanliness and environmental protection, but because its output force is relatively small, it is generally only suitable for the bending processing of some thin-walled pipes and small pipe fittings.
Application Fields
Automobile Manufacturing Industry: In automobile production, double-head pipe bending machines are widely used in the manufacturing of various pipes, such as automobile seat frames, bumpers, exhaust pipes, fuel pipes, etc. The automobile seat frame needs to bend the steel pipe into a specific shape through a pipe bending machine to provide comfortable support and safety performance. The manufacturing of bumpers also requires the use of a pipe bending machine to bend the pipes into a shape that conforms to the automotive exterior design, while ensuring that it has sufficient strength and impact resistance. The exhaust pipe requires precise bending angles and radii to ensure the smooth exhaust gas emission and the normal operation of the engine.
Furniture Manufacturing Industry: It is used for processing various furniture pipes, such as table and chair frames, bed frames, curtain rods, etc. In furniture manufacturing, the bending shape and accuracy of the pipes directly affect the appearance and quality of the furniture. For example, the bending angles and arcs of the table and chair frames need to conform to the principles of ergonomics to provide a comfortable using experience. The bending of the bed frame pipes needs to ensure its strength and stability to support the weight of the mattress and the human body. The bending of the curtain rod needs to ensure that its surface is smooth and the bending radius is uniform to ensure the smooth pulling of the curtain.
Sanitary Ware Industry: Many pipes in sanitary ware products, such as the inlet pipes of faucets, the brackets of shower heads, the flushing pipes of toilets, etc., need to be bent and processed by double-head pipe bending machines. These pipes not only need to have good bending accuracy and appearance quality, but also need to meet certain requirements for corrosion resistance and sealing performance. The double-head pipe bending machine can ensure the dimensional accuracy and surface quality of the pipes by precisely controlling the bending parameters, and at the same time, cooperate with corresponding surface treatment processes, such as electroplating, spraying, etc., to improve the corrosion resistance and aesthetics of the pipes.
Construction Industry: In construction, double-head pipe bending machines are used for processing various construction pipes, such as air conditioning pipes, water supply and drainage pipes, electrical threading pipes, etc. The bending of air conditioning pipes needs to be precisely processed according to the structure of the building and the design requirements of the air conditioning system to ensure the normal operation and aesthetics of the air conditioning system. The bending of water supply and drainage pipes needs to consider the slope of the pipes and the direction of water flow to ensure smooth drainage and stable water supply pressure. The bending of electrical threading pipes needs to ensure that its inner diameter remains unchanged to facilitate the threading of wires and protect the wires from damage.
