Stainless steel pipe cutting machine manufacturers teach you how to deal with problems in the development of pipe cutting machines?
Noise and resonance: Noise affects the comfort of users using pipe bending equipment, and is an important indicator to measure the quality of pipe cutting machines. The noise of domestic high-power pipe cutting machines is generally above 80dB, especially in places with low temperature, not only the noise is large, but also the phenomenon of resonance. The noise of foreign high-power pipe cutting machines is generally below 76dB. The frame of the stainless steel pipe cutting machine is a welded box structure, similar to a speaker, which amplifies the noise. At the same time, in places with low temperature, the motion resistance increases due to the increase of the viscosity of lubricating grease and the shrinkage of the sealing ring, which further aggravates the generation of noise. During the welding process of the frame, it is necessary to ensure the quality of the welded parts, reduce the welding deformation, and add appropriate reinforcing ribs, so that the sound box effect is difficult to form. At the same time, the use of low-temperature-resistant lubricating grease and sealing ring can reduce noise.
Problems in the development and design of stainless steel pipe cutting machine: The pipe cutting machine has problems such as the deformation rate of the elbow section does not meet the national standard, the angle compensation of the elbow is difficult to control, the service life of the chain is not enough, and the control circuit is easily damaged. These belong to the design problems, and the finite element technology analysis is adopted for the weak links, and the ideal results can be obtained by optimizing the design of the parameters. For the problem of easy damage to the control circuit, on the basis of vibration test, temperature test, function test, and life test, the qualified matching components are screened out and the parameters are optimized. In short, in the development process of the electric pipe cutting machine, there should be more tests, more field tests, and attention to details.
The support roller swings back and forth during the pipe bending process: the angle between the steel pipe and the horizontal plane is usually designed to be zero. Due to manufacturing errors and various elastic deformations in the pipe bending process, the angle cannot be ideal zero. When moving forward, the forward deformation of the support roller increases, and the included angle also increases. When the steel pipe is bent forward or backward during the bending process, the bending support roller will swing back and forth during the working process. Improving the rigidity of the support rollers and ensuring the lubrication of the rollers can make the swing close to zero.
