What are the air duct forming requirements for duct forming machine?

Duct forming machine is inseparable from the production of flange equipment, which is now basically belong to fully automatic mechanical equipment. The duct forming machine automation solves the cumbersome manual operation, which greatly facilitate the production of enterprises. When it comes to air duct forming, what are the requirements for duct forming machine? Let's look at the following.

1. Before using the duct manufacturing machine, the debugging of the feed rail should be strictly in accordance with the debugging requirements of the equipment, and the feed rail should be fixed after being adjusted to the specified position size. If the actual position of the feed rail is less than the specified position size, the mouthpiece will not be formed; if it is larger than the specified position size, the feed size is too wide and the size of the mouthpiece will be too bad to cause the two sheets to fail to bite or waste material. If the feed guides are skewed severely, it is easy to produce uneven deviation before and after the width of the mouthpiece.

2. The thickness of the bite plate should be within the specified range of duct fabrication machines of various specifications. If it is less than the minimum thickness, cracks, wrinkles, and other defects will occur easily when biting; if it is greater than the maximum thickness, it will be proportional to the square of the thickness of the plate. Due to the marked increase in the bending force, it cause abnormal damage to the forming roller, overloading of the drive system, and boring of the vehicle.

3. The processing capacity of the air duct fabrication machines are designed according to ordinary steel plate processing. Common thin steel plates, galvanized steel sheets and plastic composite steel plates all have good bite forming performance. The strength of stainless steel plates is higher than that of ordinary steel plates. Before the stainless steel plates are used to bite the openings, the spiral duct forming machine must be performed first to avoid overloading the equipment and causing excessive wear or mechanical accidents. Due to the poor plasticity of the aluminum plate, it is easy to crack during the forming of the bite, and the forming test is also required before the construction. At the same time, due to the lack of elasticity of the aluminum plate, it can not be snap-buttoned.

4. The minimum length of the bite section of the plate should not be less than 300mm, otherwise when the horizontal resistance of biting, due to little contact between the plate and the roll forming equipment, it is greater than the friction force of the forward feeding plate. which will accelerate the wear of the roller forming area.
