Before using the equipment of the air duct manufacturing machine, the commissioning of the feeding guide should be in strict accordance with the commissioning requirements of the equipment, and the feeding guide should be adjusted to the specified position and size and then fixed. If the actual position of the feeding guide rail is less than the specified position size, it will cause the bite does not form. And If the size is larger than the specified position, the size of the bite will be out of tolerance due to the wide feed, resulting in two plates cannot bite or waste materials. Besides, it is easy to produce bite width before and after uneven running defects if the feed guide rail skew is serious.
The processing capacity of the air pipe production line forming machine is designed according to the processing of ordinary steel plate. The commonly used ordinary steel plate, galvanized steel plate and plastic composite steel plate all have good forming performance. The strength of stainless steel plate is higher than general steel plate, it’s necessary to make forming experiments before using stainless steel plate, so as not to overload the equipment work, which will cause excessive wear or mechanical accidents. Due to the poor plasticity of aluminum plate, it is easy to crack when forming so that forming test should be conducted before construction. At the same time, the aluminum plate air duct cannot be bite buckle type because of its lack of elasticity of aluminum plate.
The minimum length of the bite section of the plate shall not be less than 300mm, otherwise, the horizontal resistance of the bite section is greater than the friction force of the plate sent forward due to too little contact between the plate and the forming roller at the same time. It could cause the plate to slip between the forming roller and accelerating the wear of the forming part of the roller.
The thickness of the bite plate of the air duct manufacturing machine
should be within the specified range of products of various specifications. If it’s less than the minimum thickness, it would cause cracks and corrugations and abnormal damage to the forming roller, transmission system overload and boring car and other faults would happen due to the obvious increase in bending force because the thickness is larger than the maximum thickness.
