The Design And Research Of The Steel Surface Treatment Equipment

The quality of longitudinal pipelines has great effect on the vital interests of both the country and the people. Among all the reasons causing the quality decline of pipes, the rust of materials which are used to produce the pipes is the main reason. Once the plate is placed in the humid plant without immediate use, there would be oxidation corrosion. If we don’t apply the rust treatment, it will affect the performance of the product inevitably, especially in the welding process. Even worse, it can lead to product obsolescence as well. In this paper, in order to solve problems of lower passing rate caused by rusty steel welded pipes, we have to take effective measures such as mechanical grinding sand-blasting treatment on the entire steel surface and the side panels.To comply with the technical requirements of the rust equipment, we design a set of automated steel surface treatment equipment, including steel surface mechanical rusting of the entire board surface and sandblasting equipment on steel plate edge. In this paper, we use Solidworks to establish the 3-Dimentional modeling of blasting equipment parts, and we choose he involved motor, screw, rails and others through calculations. We use the finite element software for structural to optimize the design of components and we obtain the desired results eventually. We use the finite element method to check the critical parts and we proved the rationality of the design. We use the modal analysis to check whether the vibration source is rational in the complex parts, proving that the device can avoid resonance. In this paper, rust equipment controlling systems were initially designed, the controller and servo motor control selection were discussed.In this paper, we use ANSYS / LS-DYNA finite element software to simulate the single-particle impact on the plate and at the same time we study the sandblasting process. By adjusting the speed of the sand, the size and impact angle, we analyzed the stress and energy distribution and studied the effect of sand-blasting in different conditions, which provides guidance in order to improve the quality and efficiency of blasting.
