Comparison of pipe bender and automatic pipe bender

Comparison of pipe bender and automatic pipe bender

Pipe bending machine and automatic pipe bending machine are two common equipment in the metal processing industry, they can be used for pipe processing, but their principles, characteristics and applications are different. Below we will describe in detail how the two devices compare.

First, the basic principle and classification of pipe bending machine

The basic principle of the pipe bending machine is to bend the metal pipe into a certain shape through the principle of mechanics. Pipe bending machine has a wide range of applications, the most common of which is used in construction, automotive, mechanical manufacturing and other fields for bending exhaust pipes, pipes, contours and other parts.

According to the different control methods, pipe bending machines are mainly divided into the following categories:

1. Manual pipe bending machine: Manual pipe bending machine is a simple pipe bending machine, mainly suitable for small processing places, manual operation process requires personnel to push the rod to twist the pipe, to achieve the shape of bending the pipe.

2. Hydraulic pipe bending machine: Hydraulic pipe bending machine mainly uses the basic principle of hydraulic pressure to achieve the bending process. By controlling the round trip movement of the hydraulic cylinder, the bending operation is realized.

3. CNC pipe bending machine: CNC pipe bending machine adds a numerical control system on the basis of hydraulic pipe bending machine to achieve automatic operation. CNC pipe bending machine can realize the characteristics of high bending precision, fast processing speed and high production efficiency, and is widely used in aerospace, rail transit, nuclear energy and other fields.

Second, the basic principle and classification of pipe bending machine

The pipe bender is a multi-functional pipe bender whose basic principle is to pressurize the metal pipe inside and then form a raised pipe bend. The application range of pipe bender is wide, which is mainly used in the processing of various pipes, exhaust pipes and automobile exhaust pipes.

Pipe bending machine is mainly divided into the following categories:

1. Manual pipe bending machine: Manual pipe bending machine is a manually controlled expansion pipe bending machine, which needs to manually place the metal pipe in the machine, and then control the internal expansion force through manual control.

2. Hydraulic pipe bending machine: Hydraulic pipe bending machine is a kind of expansion and bending machine through hydraulic technology, through the hydraulic cylinder, hydraulic motor and other components to work.

3. CNC pipe bending machine: CNC expansion pipe bending machine is a kind of equipment combined with digital control system, which can achieve processing objectives through CNC program.

Three, the comparison of pipe bending machine and automatic pipe bending machine

1. Working principle: The automatic pipe bending machine performs the bending task according to the preset program and automatically completes the entire processing process; The expansion pipe bending machine is to make the metal pipe expand in the interior to form a certain shape by pressure.

2. Suitable for processing materials: automatic pipe bending machine is suitable for processing some regular bending, high size requirements of the pipe, and the required material must be as if the radius of the metal pipe, and the expansion pipe bending machine can be applied to bending and expanding the diameter of the processing of various metal materials below 20 mm.

3. Applicable processing methods; Automatic pipe bending machine is controlled by computer program, suitable for batch processing and production, and can maintain a certain processing accuracy; The expansion and bending machine can be applied to the processing of special and small batch parts.

4. Processing accuracy: The automatic pipe bending machine has high processing accuracy, which can reach ±1 degree accuracy, while the processing accuracy of the pipe bending machine is relatively low, generally reaching ± 5mm accuracy.

In general, automatic pipe bending machine and pipe bending machine are two kinds of equipment with different characteristics and advantages. When choosing, users should combine their own processing needs and actual conditions to purchase. If it is a high-precision and high-volume processing task, it is recommended to choose automatic pipe bending machine; If it is a small batch, special shape or metal pipe processing task with an internal diameter of less than 20 mm, it is recommended to choose a pipe bender.
