How to solve the problem of wave pattern in sheet metal processing

Recently, the technical staff of the plate companies often consulted us, why the wave pattern appeared in the processing of the sheet, which affected the quality of the sheet.

When the wave pattern is heavy, the direct team can see it, the measured thickness, the data of each part has changed, and the processed plate can only be reduced to a low-grade product. When the wave pattern is light, the visual is almost no, but if it is from one Looking at the side, I can see that it is very difficult to get past the experience of an experienced customer, resulting in a reduction in the quality of the board.

In this regard, we consulted the technical staff of Linyi Delide Machinery. They said that the reason for the wave pattern is very simple, because the sander is constantly oscillating during work. There are many reasons for the shock phenomenon. Kind: First, because the model is small, the power used is too large, and the processing strength and speed are increased. Especially the bracket sander is more prone to shock due to congenital reasons, and the products on the market have 90. More than % of the bracket type; if it is a frame sander, this problem may not be. Of course, there are some small sanding machine manufacturers because of their own lack of random configuration is also one of the reasons. Second, the sander used bearings The error is large, causing shock. Third, the sanding roller of the sanding machine is not standard, there is an error between the parts. The fourth is the abrasive belt, and the transmission with shrinkage will also cause error ripple.

The improvement method is as follows: as far as possible to combine the existing models and structures, configure the appropriate motor, it is not easy to increase the processing speed and processing strength arbitrarily to facilitate the stability of the machine. Second, try to select high-quality bearings with less error, Delide's technology The staff recommended that it is best to use German imported bearings. Third, the sanding machine is often used for precision maintenance, timely adjustment and adjustment. The fourth is to purchase the overall frame type sanding machine as much as possible, although the price is slightly more expensive, but the quality of the produced sheet Relatively improved. At the same time, the conveying part should also say that the error caused by the roller conveyor is smaller.
