How to deal with the noise of automatic vertical tube expander?

Full automatic vertical tube expander is a common tube expander. In the process of operation, the temperature is reliable and the energy consumption is less. It is an indispensable mechanical equipment in the enterprise. However, there are often noises when using it. Why? How should we deal with this phenomenon?

The noise of the automatic vertical tube expander is usually caused by a large amount of friction noise during the bending process. This is mainly due to the noise generated in the bending and stretching process of the pipe and the bending mandrel. We need to apply stretching oil to the mandrel of the bending machine before bending, so that it can be fully lubricated. When the bending pipe is stretched, it can be subject to less friction noise except.

There is noise in the process of use, which is mainly because the oil pump when the oil suction, because the chassis hydraulic oil is not enough enough and the air is sucked into the noise generated, we need to check the tube or pipe cutting machine chassis back oil pipe back out of the oil whether there is a bubble, if there is air suction into the oil will appear a lot of bubbles.
