One-stop Bending Solutions For Wires, Tubes And Pipes
Introduction
The CNC pipe bender is a pipe bending processing equipment that can realize the winding bending of pipes with one bending radius (single layer) or two bending radii (double layer) in a cold state. The CNC pipe bender has the advantages of simple mold replacement, fast setting, high reliability, and fast movement speed. It is widely used in sports goods, nuclear industry, industrial boilers, aerospace, shipbuilding and other fields.
Processing application of pipe bender
The function of the pipe bender is to bend various types of metal pipes, such as carbon steel round pipes, stainless steel round pipes and square pipes. In the manufacturing process of automobiles, processed pipes are needed in many places. For this kind of batch production, CNC pipe bender is more recommended. The advantages of high efficiency, high precision, and easy use can be reflected in the manufacturing process.
In terms of usage, the automotive industry is the single industry with the largest number of pipe benders. Pipes are indispensable in the fuel, air conditioning, exhaust, steering, braking and other systems of automobiles.
Comparison between CNC pipe bending machine and ordinary pipe bending machine
Compared with ordinary pipe bending machine, CNC pipe bending machine has the following characteristics: high processing accuracy and stable processing quality; it can carry out multi-coordinate linkage and can process parts with complex shapes; when the processed parts are changed, generally only the CNC program needs to be changed, which can save production preparation time; the pipe bending machine itself has high precision and high rigidity, and can choose favorable processing dosage, with high productivity (generally 3~5 times that of ordinary pipe bending machine); the pipe bending machine has a high degree of automation, which can reduce labor intensity; batch production, product quality is easy to control; the quality requirements for operators are low, and the technical requirements for maintenance personnel are high.
Types of CNC pipe bending machine
There are many types of CNC pipe bending machines. According to different driving modes, CNC pipe bending machines can be divided into electro-hydraulic CNC pipe bending machines, electric CNC pipe bending machines, etc.; according to different degrees of automation, CNC pipe bending machines can be divided into fully automatic CNC pipe bending machines and semi-automatic CNC pipe bending machines. At present, fully automatic CNC pipe bending machines are the mainstream products in the CNC pipe bending machine market, accounting for 70% of the market. Fully automatic CNC pipe bending machines usually use servo motor drive systems as core components, which can achieve high-precision requirements for pipe bending processing.
Computer control systems, single-chip microcomputers, hydraulic systems, and mechanical systems are the main components of CNC pipe bending machines. During the operation of CNC pipe bending machines, limit switches can be used to set the required bending degree of pipes, and the database can also store multiple sets of bending data for easy and fast operation.
Application in automobile manufacturing
Let’s talk about the application direction of CNC pipe bending machine in automobile manufacturing. The number of cars is constantly increasing, and the family replacement cycle is also shortening. The current hot new energy vehicles, with the development of technology and the increase in understanding of them, are also increasing their market share in the automobile market. This has increased the processing application of CNC pipe bending machines in the automotive industry. Some places where metal pipes are used in the automotive industry, such as exhaust systems, fuel systems, braking systems, cooling systems, air conditioning systems, body structures and chassis, etc.
For the processing of these pipes, with the continuous advancement of pipe bending machine technology, some factories will use all-electric CNC pipe bending machines: 1 All-electric CNC pipe bending machine is a precision equipment used in automobile manufacturing. It is driven by an electric motor and can accurately control the bending process, so that complex and delicate pipe shapes can be produced with high precision.
2 Hydraulic CNC pipe bending machine, the advantage of this equipment is that it has strong power and strong bending force to handle high-strength materials, which is suitable for key components such as automobile chassis and frames.
CNC pipe bending machines are widely used in a wide range of fields, with automobiles being the largest demand end, accounting for nearly 60%. In the automotive field, CNC pipe bending machines are mainly used for the bending of automotive parts, including radiators, automobile headrest rods, exhaust pipes and other pipes. Driven by downstream demand, the development speed of the CNC pipe bending machine industry is accelerating.
Considering the output of automobiles, the application of pipe bending machines in the automotive industry can be imagined.
Application in automobile air conditioning pipe processing
Automobile air conditioning pipeline is an important part of automobile air conditioning system. It connects four important parts: compressor, condenser, expansion valve and evaporator. Air conditioning pipeline is mainly composed of aluminum tube, hose, joint and other parts. According to the state of refrigerant, it can be divided into gaseous tube and liquid tube. According to pressure, it can be divided into high pressure tube and low pressure tube. The automobile industry usually has relatively high requirements for precision, efficiency and processing of complex shapes, and requires batch production and material diversity. The advantages of CNC pipe bending machine are reflected, including high precision, convenient programming, adjustment of production process at any time, suitable for complex shape processing, complex 3D bending can be realized, and with mold, the pipeline processing can be formed in one time. The technical advantages of CNC pipe bending machine make it an important equipment for air conditioning pipeline processing.
What are the different requirements for CNC tube bending machines in the automotive industry?
1.Due to the large output, the actual production efficiency of the equipment is required to be high.
This high efficiency is directly reflected in the high speed of the three main axes of the tube bending machine (tube feeding, tube rotation and tube bending axis rotation). Another factor that affects efficiency is the interpolation of each axis, that is, when one axis moves, another axis also moves. The specific manifestation is in the process of switching from one bend to the start position of the next bend. For example, the tube clamping block retreats while the tube bending axis resets, and the tube feeding process rotates at the same time. This can also save time.
2.The shape of the pipe is complex and requires multi-layer mold function.
Due to the limitation of automobile installation space, some pipe fittings are designed with different bending radii for each piece, and even have bends connected. In this case where there is no straight line between the two bends, special design is required in the mold design, which will first have at least one more layer of mold than the conventional mold. If the workpiece itself has more than one bending radius, this means that the mold will have at least three layers. Therefore, a tube bending machine with multi-layer mold function must be selected. When choosing a tube bending machine, the effective die height must be considered. Note that it is the effective die height, not the two-layer or three-layer die mentioned in the pipe bending machine sample. On a pipe bending machine with a multi-layer die function, the translation and vertical movement of the elbow realizes the die layer change. If these two motion axes are controlled by servo motors, the position of the elbow in the vertical direction can stay at any position within the stroke. Therefore, the relationship between the effective die height and the thickness of the die layer determines the number of layers of the die. For example, if the die height is 100mm and the die layer height is 20mm, 5 layers of die can be installed.
In the selection of the multi-layer die function, another parameter to pay attention to is the maximum die radius difference, which is related to the translation stroke of the elbow.
