Best 5 cnc Tube Bending Machine Manufacturers in China

CNC tube bender has greatly improved tube bending quality. In the past, metal manufacturing plants required technicians to manually bend small-diameter tubes, which often resulted in incorrect measurements, low precision of angles and high scrappage rate of tubes. The good news for us today is that we have come a long way from those days. Nowadays, we can bend tubes to exact measurements using cnc tube bender machines that have been designed to perform the job perfectly. These machines are commonly known as CNC tube bending machines (or CNC tube benders) because they are perfect combination of CNC tecnology and pipe bending machine. Instead of human control, the brain of a cnc tube bender is a microcomputer and servo motors of the cnc tube bender can insure the exact movements of the executive components, so that we can get bent tubes with high accuracy.

What is Tube Bending?

There are many instruments that require bent tubes, including stair railings, handles, trombones, furniture frames, air conditioning equipment, automotive parts, and much more. Bent tubes are used for changing the direction of conduits for gases and fluids in exhaust systems, hydraulic lines, pipelines, etc. Wide use of bent tubes makes tube processing machines producers do continuous improvement and development to get best bending machine.

Tube bending machine manufacturers produce vatriety of pipe bending machines to meet cumtomers’ production requirements.

1.Pipe bending machine take advantage of pulling force to bend tubes.

One side of the tube is fixed on the rotating arm with clamp and the other part of the tube pass through three horizontal support rollers, the rotary wheel and rotating arm are integrated. When the rotating arm rotates, it drives the pipe to produce shape change.

2.The push rod pushes the tube out through the bend die and rolls it between the supporting rollers on both sides to form it. The bend die and support rollers have groove that is the same as the diameter of the tube to bend.

3.Each bend die has a groove that matches the shape of the tube. The tube is pressed against the rotary bend die that can rotate around the axis by the clamp die and pressure die. The pressure die and the bend die rotate to drive the tube to rotate together with the rotary bending die under the action of radial pressure and friction of the clamp die to realize bending work. Currently, most of the tube processing machines producers manufacture pipe bending machines appling this theory.

How Does A CNC Tube Bending Work?

After years of hard work cnc tube bending machine manufacturers get the best bending machine— cnc tube bender. CNC refers to computer numerical control. CNC tube bending machines work well with minicomputers for controlling the executive component parts. The feeding, rotation of tubes and bending process are all controlled by the minicomputer. Servo motors of the cnc tube bender guarantee constant bending and precise bending angles. A cnc tube bender is a automatic tube bender, after introducing all shape datas of tubes that are needed, the cnc tube bender can perform the bending work perfectly and automatically.

The following five components play a major role in the clean, precise bending of tubes on CNC tube benders:

  • The bend die of the cnc tube bender is a round part which can determine the radius of the bend.
  • Clamp die: As the bend die rotates, the clamp die gripgrips the tube to hold it in place.
  • Wiper dies:In the inside area of the bend, this part prevents wrinkles from forming.
  • Mandrel: The mandrel is placed into the tube to prevent wrinkles inside the bend, this part works with the wiper die.
  • Pressure die: Pressure die applies pressure to tubes to cause the shape change of the tube.

These bend dies work together to produce the perfect bend according to the computer’s specifications.
