1. The average force principle of each channel of the spiral duct forming machine, the average roller of the whole line is subjected to the average force, the wear is balanced, and the service life of the roller is prolonged.
2. The arc part of the spiral duct forming machine is the core part of the slide rail. The arc position after the first few press forming, when the vertical pass is rolled up, the formed arc should be formed by the upper and lower rolls or the horizontal wheel. Effective tube bundle protection is carried out, otherwise the material will change its arc position during the stretching process.
3. Spiral duct forming machine rolling stability problem, the production often encounters the problem of material yaw in the raceway, in fact, the single set of rollers is asymmetrical, the left side is stressed, the material is yaw to the right; Strong, the material is biased to the left.
