Take you to know the pipe bending machine

Pipe benders are now very popular in the market. For many small businesses, home workshops, or occasions where piping is required in large enterprises, such as pressure oil pipes on construction machinery, pipe fittings of machine tool builders are not difficult, simple manual pipe benders are likely to be suitable. The pipe bending machine adopts manual tightening and mechanical bending, the machine structure is simple, and the control elements are very few. This article will describe in detail on what is a tube bender.

Introduction of pipe bender

Pipe bending machines can be roughly divided into CNC pipe bending machines, hydraulic pipe bending machines and so on. Mainly used for electric power construction, highway and railway construction, boilers, bridges, ships, furniture, decoration and other aspects of pipeline laying and repairing. It has the advantages of multiple functions, reasonable structure and simple operation. In addition to the pipe bending function, this machine can also use the cylinder as a hydraulic jack. Compared with the CNC pipe bending equipment, it has the characteristics of low price and convenient use. It occupies the leading product position in the domestic tube bending machine market.

Features of tube bender

1. The pipe bending machine adopts touch screen and numerical control module, dialogue operation, simple and easy program setting;

2. The bed structure is stable and not easy to deform;

3. Each file can set 16 bending angles, and the memory can store 16 sets of files;

4. With slow positioning function, the roller bending machine angle is stable, and the repeatability is up to 0.1°;

5. The error message is displayed on the screen to help the operator eliminate it immediately;

6. Provide self-developed coordinate conversion elbow processing values. The software can be installed on the desktop computer to edit and calculate.

Classification of pipe bending machines

Categories include: hydraulic electric pipe bender, horizontal hydraulic pipe bender, multifunctional rolling pipe bender.

The electric pipe bender is purely electric, driven by a motor, a transmission, and driven by a gear chain; the hydraulic pipe bender separates the bending action, and uses hydraulic pressure to drive the clamping and retraction, and the bending pipe retreat Bending, auxiliary advance and auxiliary retreat, core advance and retreat, etc. The hydraulic pipe bender is an ordinary plane-wound automatic pipe bender. The bending action is automatic when the pipe is produced, but its feeding, three-dimensional corners, etc. can only be completed manually by the fixed length and angle positioning ruler.

The CNC pipe bender uses a servo motor instead of hydraulic pressure to control the feeding and retreat of the trolley, the rotation of the tilt angle, the retreat of the bend, the auxiliary advance and auxiliary retreat, the head lifting, etc., but it is clamped, retracted, and inserted. The core removal is still driven by hydraulic or pneumatic pressure. The difference from the hydraulic pipe bender lies in the continuous barrel produced, the processing precision and the three-dimensional forming of the pipe.

Roller bending machine forming limit

The forming limit of pipe fittings should include the following:

1) The maximum elongation deformation in the tensile deformation zone outside the neutral layer does not exceed the allowable value of material plasticity to cause rupture;

2) In the compression deformation zone inside the neutral layer, the part of the thin-walled structure under the action of tangential compressive stress will not exceed the instability and wrinkle;

3) If the pipe fitting has ellipticity requirements, control its cross-section to produce distortion;

4) If the pipe has a strength requirement to withstand internal pressure, control the forming limit of its wall thickness reduction.

As a kind of equipment with a very wide range of applications in industrial equipment, the pipe bender can bring great convenience to our lives. Zhangjiagang King-Macc Machinery Manufacturing Company can provides the satisfied tube bending to the customers according to the accumulated designing experience and more experiments. Our products including Pipe Cutting Machine, Pipe End Forming Machine.
