General FAQ


What is mandrel of pipe bending machine?

When bending steel pipes and aluminum pipes, the mandrel of the pipe bending machine must be used for difficult work. Bending smaller radii, thin tubes or harder materials may cause unsatisfactory results. In these cases, the mandrel may come in handy. The purpose of the mandrel is to prevent the tube from collapsing.

What is wiper die of pipe bending machine?

The wiper die of the pipe bender is placed behind the bending die. The goal is to avoid any bumps on the inner radius.During the molding process, the material becomes plastic during the bending process. May cause large wrinkles and deformation. Therefore, adding a wiper mold after bending the mold helps smooth the surface.

What is press die of pipe bending machine?

The press die of the pipe bender ensures that the pipe follows the contour of the bending die.

What is clamp die of pipe bending machine?

The clamping die of the pipe bender presses the pipe onto the bending die. Its main purpose is to prevent the pipeline from slipping.

What is bend die of pipe bending machine?

The bending die, also called the bending die or the fillet die, is the most important part of the rotary stretch CNC pipe bender. The tube is clamped on the bending die, and the drawing process will produce the necessary bending. The choice of mold is very important because the inner radius of the tube depends on it.

What is minimum bending radius of pipe bending machine?

The minimum bending radius is the minimum allowable radius that the cable can be bent. During the installation process, the cable will bend or bend under various environmental conditions. Cables are usually bent around conduits or underground pipes.

What is induction bending and cold bending?

Cold bending refers to all types of bending in which pipes are bent without any additional heat. Induction heating bending usually only refers to different types of induction bending. Induction bending is an efficient pipe bending method because it is fast, accurate and almost error-free.

What is the main purpose of induction heating pipe bending?

The main purpose of the induction heating pipe bender is to make the pipe bend without any bending (collapse under pressure), and to minimize curling and flattening. It is important that the pipe must maintain its shape, because a deformed pipe may rupture under pressure, rupture, and generally look less attractive.

What does the R and L mean on a cnc mandrel tube bender?

Assume that the bending machine is in good condition. Look for the marks "R" and "L", and "0" and "45" on them. If you start measuring from the left and want to bend 90 degrees, tilt 0 and set the measurement mark on "L". If you start measuring from the right, add "R".

How is bend length calculated when using induction pipe bending machine?

Lf = the flat length of the metal plate.BA = bending allowance.BD = bend deduction.R = internal bending radius.K = K factor, which is t /T.T = material thickness.t = the distance from the inner surface to the neutral line.A = bending angle (in degrees) (the angle at which the material is bent)

What is hydraulic pipe bending machine?

We provide high-quality hydraulic pipe benders. These are motor-driven, used for large-radius large-size ERW elbows, very suitable for "C" size 3/8" to 6" gas, water, steam DIN 2440/2441, maximum bending 90 degrees. 40 on request. The provided tube bender array is widely used.

How does a pipe bending machine work?

This is the most common type of pipe bender. First, the machine operator uses the clamping die to fix the pipe or pipe to the machine. Then, the bending mold starts to rotate around its axis. At the same time, fixing the pressure mold ensures that the tube follows the radius of the bending mold.

What is straights between bends of CNC mandrel tube bender?

If your part requires multiple elbows, then we will need a minimum straight length between the two elbows. This is also called the clamp length. Using our tool list, you can see the minimum clamp length of any size tube and the related centerline radius bending mold from our inventory tools.

What is degree of bend of CNC pipe bender?

Bend angle. This is on the outside of the bend
