How to determine the model of pipe bending machine

The bending method of our factory is mainly cold bending. The models are hydraulic bending machine and three-roll bending machine. The "pipe bending machine" is a curved "tube". In fact, it can also bend "I-beam". "channel steel", "angle iron" "wire", etc.; can also be rolled coil, "u" type tube, half tube, coiled tube and so on.
In reality, many customers call me and start asking how much the bender is? This makes me unable to answer positively: just say a price, it is irresponsible to the customer; not to mention it, I feel that I am not enough! Here, I will tell you in detail how to properly use the bender?
The company purchases pipe bending machines in order to reduce labor intensity, improve production efficiency, improve product quality, and thus enhance the competitiveness of enterprises. The savvy boss will choose the model that is most suitable for their own production (the best for their own is the best). of)! What kind of pipe bending machine is most suitable for its own production?
First of all, according to the actual production situation, determine the pipe diameter range of the elbow. Many pipe fittings use pipe bending machines for various pipe fittings. Each pipe bending machine is not a panacea. It has its own parameters that limit the bending capacity. For example: DW38NC hydraulic pipe bending machine The maximum diameter of the bend is 38.1mmX3.0mm (based on ordinary carbon steel pipe material, the wall thickness varies according to the material); the maximum diameter of the DW120NC hydraulic pipe bending machine is 120.3mmX8.0mm! The price of each type of pipe bending machine is different. Besides, if you choose an oversized model, it will be a waste of resources. If the selected model is too small, there will be a laborious feeling of "small horse-drawn cart". In turn, affect the service life of the machine!
Secondly, it is necessary to determine the elbow parameters of the largest pipe fittings in the range of the elbow, including: 1. Pipe fitting material (steel pipe, stainless steel pipe, aluminum pipe, etc.); 2. Pipe section (round pipe, square pipe, angle iron, etc.) 3, tube outer diameter; 4, tube wall thickness; 5, bending radius (refer to the tube diameter); according to the above-mentioned bending parameters, so as to choose the most suitable bender, is the best decision
