The Advantages of the Spiral Duct Machine and the Precautions for the Design and Production Process

Spiral duct machine is a machine for producing spiral duct. The helical tube is a thin-walled tube made of metal strips and formed into a spiral shape. It is round, not welded, and formed in one shot. It is mainly used for air supply and bulk material transport. It replaces the traditional white iron duct. It is an air duct that automatically produces straight pipes without manual mobilization.

Ⅰ. The two advantages of the spiral duct machine are reflected in the following two aspects:

1. The production speed of the spiral duct machine is very fast, and the delivery speed is very fast, which greatly improves the production efficiency and wins huge benefits for the enterprise. The area of the spiral duct machine is small, and the operation is simple and easy to realize.

2. The internal protection of light steel keel is multi-faceted, the main material is excellent, the pressure is large, it is not easy to deform, the frame structure has strong adhesion and long service life.

Ⅱ. Matters needing attention in the process of designing and producing spiral duct machine

Formaldehyde-free environmental protection fireproof and thermal insulation air duct can be selected. This is a high-tech environmental protection energy material. It has a variety of excellent properties, not only in terms of good thermal insulation performance, but also can reduce air leakage rate and improve air output rate. , reduce friction loss, formaldehyde-free environmental protection fire insulation duct is also very high-quality in terms of environmental protection performance, it can bring clean air, thereby improving indoor air quality, and at the same time, it has the advantages of reducing noise and keeping the environment quiet.

In the process of designing the spiral duct machine, the principle of average force should be followed, so that each pass and roller can be equally stressed, so that the degree of wear will be very balanced and its service life will be extended. Secondly, pay attention to the rolling stability of the spiral duct machine.

When designing and producing, pay attention to the symmetry of the roller processing, and calculate the denatured neutralization layer and the amount of materials in advance. Thirdly, the problem of bending and twisting may occur in the production process. This phenomenon is mainly caused by the unbalanced force. The best solution is to balance the force in the design. After accurate processing, pay attention to the roller processing during production. Accuracy and machining protection of orbital arcs.
