The bending of metal means changing the angle of the sheet or parts of the sheet, for example, to bend the sheet into shape V or U. Generally, there are two ways of bending: one is bending with a die, which is used when the material has a complex structure, small-sized and with a need of a large quantity; the other is bending with a machine, which is used to process the large-sized parts with a small quantity.
Die bending is used when the quantity is over 5000 and the size of the part is not very large (normally it will be 300*300). In order to prolong the life of the die, the design of the parts should use a round angle. It is not beneficial for the forming of the bend If the angle of the bending is too small. Usually the height of the bend L≥3t.
Machine bending uses machines to bend. The bending machines are divided into two kinds. One is ordinary machines and the other is CNC machines. In our company, we have two CNC bending machines, one is for bending metal sheets, and the other is for bending pipes. CNC machines are used to bend the parts with a high requirement of quality and irregular shapes. Its principle is using a bending knife (the upper die) and the V-shaped channel (the bottom die) to bend and form the parts.
Its advantages are easy to clamp, accurate to fix position and fast in speed.
CNC Pipe Bending Machine
CNC pipe bending machine is a mechanical equipment controlled by CNC technology, mainly used for bending processing of metal pipes. It has the following characteristics:
High precision: CNC pipe bending machines use a CNC system to control parameters such as force, speed, and position during the bending process, enabling high-precision bending processing. By programming and adjusting, the bending angle and radius can be controlled to ensure the accuracy of the size and shape of the bent pipe.
Multifunctional: CNC pipe bending machine can achieve processing of various bending methods and angles, such as single bending, multi bending, complex curves, etc. By replacing different bending molds and adjusting parameters, the bending needs of different shapes and sizes can be met, providing flexible processing options.
Automation operation: CNC pipe bending machines can achieve continuous mass production and improve production efficiency through CNC programming and automation operation. Operators only need to set up and monitor the program, reducing the complexity and error rate of manual operations.
Quick adjustment: CNC pipe bending machines have the characteristic of quick adjustment, which can quickly replace different sizes and shapes of pipe bending processing through the setting and adjustment of the CNC system, reducing adjustment time and labor costs.
Data recording and analysis: CNC pipe bending machines can record and store data for each bend, including bending angle, force, position, and other information. These data can be used for quality control and production process analysis, helping to improve production efficiency and quality management level.
Visual interface: CNC pipe bending machines are usually equipped with a visual interface for easy and intuitive operation. Operators can set and monitor parameters through touch screens or computer interfaces, improving the convenience and efficiency of operations.
