Square Tubes Bending

The Bending Technique of Square Tubes - The Secret of Not Deforming

1. Bending techniques for square tubes

Square tubes are one of the commonly used building materials in modern architecture, but they are prone to deformation when bent. To avoid this situation, we need to master some techniques.

The first step is to choose the appropriate bending process. In practical operation, we can use two methods: cold bending and hot bending. Cold bending refers to bending at room temperature, suitable for soft square tubes. And hot bending refers to bending at high temperatures, which can handle harder square pipes.

The second technique is to use the bending machine correctly. When using a bending machine, it is necessary to choose the appropriate tool based on the size and shape of the square tube. At the same time, it is necessary to adjust the pressure of the bending machine according to the thickness of the square tube before bending.

The third technique is to control the bending force. When bending, the square tube cannot be bent into place at once and needs to be bent multiple times. The bending force should be appropriate each time, not too large or too small. In addition, it is necessary to check for any deformation of the square tube after each bending and make timely adjustments.

2. How to avoid deformation of square tubes

In addition to mastering bending techniques, there are also some methods that can help you avoid deformation of the square tube.

(1) Pre heat treatment

Before bending, we can preheat the square tube. Preheating can make square tubes softer, easier to bend, and also reduce the risk of deformation.

(2) Using molds

When bending square tubes, molds can be used for operation. The mold can accurately control the shape and size of the square tube, avoiding its deformation.

(3) Appropriate bending radius

When bending square tubes, it is important to choose the appropriate bending radius. A too small bending radius can cause deformation of the square tube, so it is necessary to choose the appropriate size for bending.

(4) Processing edges

Deformation is prone to occur at the edges of the square tube, so we need to handle the edges of the square tube before bending. Polishing or cutting machines can be used to ensure the shape and size of the square tube.

In short, mastering the bending techniques of square tubes and adopting corresponding methods can help us avoid deformation of square tubes during the bending process.
