Analysis on the Second Line Biting Machine of Air Duct Production Line and Matters Needing Attention

Ⅰ. The second line of the air duct production line bite machine

In the process of using the second line of the air duct production line, the role of the bite machine cannot be ignored. It is mainly used to process and shape the plate. At this time, we need to pay attention to its use method, because only reasonable operation can ensure the standard forming of the plate, which in turn has a great impact on the quality and function of the air duct.

The thickness of the sheet that needs to use the bite machine must be within the range specified by the manufacturer, because if it is smaller than the minimum rated thickness, then there may be cracks or wrinkles during the bite; However, exceeding the maximum rated thickness, the bending force will increase sharply, resulting in abnormal damage to the formed rollers, overloading of the transmission system and failures such as car jams.

The minimum length of the bite section of the second-line sheet of the air duct production line should not be less than 300mm. Otherwise, the contact between the sheet and the forming roller will be too little at the same time, which will cause the horizontal resistance at the bite to be greater than the frictional force of the sheet being fed forward. The sheet slips between the forming rolls and accelerates wear on the forming parts of the rolls.

The adjustment of the radially reserved clearance of the upper and lower forming rollers requires not only the proper tightness, but also the consistency of the front and rear. If the reserved gap is too small, it will be difficult to feed the material, and even after forcibly feeding, the bite will crack seriously; if the reserved gap is too large, the shape of the bite will be irregular or the sheet will slip between the forming rollers.

Every link produced by the second line of the air duct production line is very important. If you are not careful, the final molding of the air duct will be affected, and the previous efforts will be wasted.

Ⅱ. Precautions for the use of the second line of the air duct production line

The second line of the air duct production line plays a very important role in many production enterprises, but many people do not know much about its maintenance and use precautions, so what problems should be paid attention to in the process of use? ?

1. When transporting the air duct production line, it is best to choose a machine for lifting. If it must be handled manually, then pay attention to the uniform force to avoid damage to the machine due to excessive force.

2. Regularly add lubricating oil for maintenance, which can reduce wear and tear.

3. Pay attention to ensure the cleanliness of the surface of the machine. If we do not use the machine for a long time, we must pay attention to coating the surface of the machine with a layer of grease.

4. Always check the working conditions of the air duct production line. If there is a problem in the inspection, it needs to be repaired in time.

5. It is necessary to carry out a regular maintenance for the second line of the air duct production line. Generally speaking, the maintenance cycle is half a year, and the machinery and equipment must be disassembled for inspection.
