| Comparison of pipe bender and chain pipe bender
In the modern manufacturing industry, the forming and processing of pipes is an indispensable link. Pipe bending machine and chain pipe bending machine are two common pipe bending equipment, widely used in construction, automotive, aerospace, machinery and other industries. Although their main function is to bend the pipe, there are significant differences in structure, working principle, scope of application, advantages and disadvantages. This article will explore the comparison of these two devices in depth to provide readers with a comprehensive understanding.
1. Basic concept and structure
**1. Pipe bending machine **
Pipe bender is a kind of mechanical equipment specially used for bending metal pipes. It bends the tube in a variety of ways (such as rolling, forging, pressure, etc.) according to the desired Angle and radius. There are various types of pipe bending machines, mainly including CNC pipe bending machines, hydraulic pipe bending machines, mechanical pipe bending machines, etc. Its basic structure usually consists of the following parts:
- ** Host frame ** : The structure that carries the entire equipment to ensure the stability and strength of the equipment.
- ** Bending structure ** : Responsible for bending the pipe, generally by the drive motor, reducer, transmission device, etc.
- ** Control system ** : can be divided into manual and automatic control, modern pipe bending machine mostly uses CNC system, can achieve accurate control.
- ** Feeding device ** : The pipe is fed into the bending area to ensure the continuity of processing.
**2. Chain pipe bending machine **
Chain pipe bending machine is a specific type of pipe bending machine, which mainly uses the way of chain transmission for bending processing. Its working principle is to drive the pipe bending through the movement of the chain, which is suitable for pipes with larger diameters and thicker walls. The basic structure of the chain pipe bender is similar to that of the pipe bender, but it is:
** Chain drive system ** : Through the chain tension and relaxation to achieve the movement and positioning of the pipe, to ensure the stability of the processing process.
- ** Clamping device ** : The specially designed clamping device can firmly hold the tube when bending, preventing sliding during processing.
- ** Bending mold ** : Different from the general pipe bending machine, the mold design of the chain pipe bending machine is more complex to adapt to different diameters and shapes of the pipe.
#### Two, the working principle
**1. Pipe bending machine **
The working principle of pipe bending machine is relatively simple, usually divided into the following steps:
- ** Feeding ** : The pipe is fed into the curved structure.
- ** Positioning ** : Precise positioning of the beginning bending position of the pipe through the control system.
- ** Bending ** : The drive system starts, the bending structure begins to exert force on the pipe, and the pipe is gradually bent to the required Angle.
- ** Discharge ** : After the bending is completed, the control system releases the clamping device and discharges the processed pipe.
**2. Chain pipe bending machine **
The working principle of the chain pipe bender is more complex. The main processes include:
- ** Feeding and clamping ** : The chain drives the pipe into the bending area, while the clamping device tightly holds the pipe.
- ** Chain drive ** : Through the movement of the chain, the pipe is gradually pushed along a preset path.
- ** Bending ** : Under the push of the chain, the pipe is subjected to uniform pressure in the bending mold to complete the bending.
- ** Discharge ** : After the bending is completed, the chain is relaxed, the clamping device is released, and the pipe is discharged smoothly.
####. Scope of application
**1. Pipe bending machine **
Because of its flexibility and variety, pipe bending machines are suitable for the tube processing needs of many industries, including:
** Construction industry ** : Used for bending and connecting structural pipes.
- ** Automobile manufacturing ** : Used for the production of automobile exhaust pipes, frames and other components.
- ** Mechanical manufacturing ** : For the processing of equipment shell, bracket, etc.
- ** Aerospace ** : For high-strength, high-precision pipe processing.
**2. Chain pipe bending machine **
Chain pipe bending machine is more suitable for processing large diameter and thick wall pipe, mainly used in:
- ** Oil and gas ** : For the laying and connection of pipelines to ensure the stable transmission of energy.
- ** Chemical industry ** : Piping systems for chemical equipment.
- ** Shipbuilding industry ** : Used for strengthening and connecting hull structures.
- ** Large machinery manufacturing ** : Frames and support structures for large equipment.

- ** Production efficiency ** : Compared with the chain pipe bending machine, its production efficiency may be low, suitable for small batch production.
*2. Advantages and disadvantages of chain pipe bending machine **
- ** Advantages ** :
- ** High efficiency ** : Chain pipe bending machine can quickly handle large diameter and thick wall pipe, suitable for mass production.
- ** Good stability ** : The chain drive system provides a smoother processing process, reducing the deformation of the pipe during bending.
