Let's briefly discuss the quality issues of fully automatic duct production lines and the factors to consider during material cutting.
How to ensure the quality of a fully automatic duct production line
The quality of an automatic duct production line will significantly impact the overall work efficiency and effectiveness of the ducts. Today, a duct production equipment manufacturer will guide you through the world of quality inspection processes for automated duct production lines that you must understand.
1. First, check if the duct manufacturer has passed ISO9001 quality standard certification. Only the quality of certified products can be relatively guaranteed.
2. Second, understand the entire duct production quality system and operation. Because fully automatic duct production lines are relatively expensive, it is necessary to choose someone to conduct an on-site inspection before making a decision.
3. It is also necessary to understand the duct manufacturer's subcontractors. The manufacturers of supporting products for the automatic duct production line must also pass this certification.
4. It is necessary to investigate the technological equipment level of the duct manufacturing enterprise. Process equipment is an important material means to ensure product quality. If the above points are done well, the quality of the duct production line can be better guaranteed. In fact, for deep procurement of mechanical products, regardless of industry regulations, product quality is an untouchable red line, especially for fully automatic duct production lines, which have high requirements for specifications and quality.
In principle, as long as the above four points are done well, qualified fully automatic duct production lines can be purchased during procurement.
What factors should be considered when processing and cutting materials for a fully automatic duct production line?
When cutting materials for a duct production line, be sure to be careful. Understanding the relevant factors is very beneficial for later work.
1. The thickness of the ventilation ducts and fittings should be indicated, the external dimensions of the rectangular ducts should be calculated, and the outer diameter of the circular ducts should be calculated. The thickness of thin steel plates, zinc steel plates, aluminum plates, and stainless steel plates used for ventilation is generally within the range of 0.5-2 mm. After expansion, the impact on the dimensions is not significant, and it can be ignored during expansion layout. However, for thick-walled ducts and components with special requirements, when the wall thickness is greater than 2 mm, the influence of the wall thickness should be considered. That is, for circular ducts, the middle diameter (outer diameter minus wall thickness or inner diameter plus wall thickness) should be used as the standard when calculating the diameter. For rectangular ducts, the expansion is still calculated according to the external dimensions of the duct.
2. The key link in expansion and material cutting is to reserve the bite-in allowance and assembly flange allowance. When expanding and cutting thin-plate ducts, pipes, and components, the connection method of the thin plate and whether the interface of the nozzle, pipe, and component has a flange should be considered so that a certain allowance can be left when expanding and cutting.
That's all for today's explanation. Thank you for watching, and see you next time.
