The work of the rolling tube is simply to reduce the roughness of the surface of the workpiece. Let's take a brief look at how the rolling tube works!
When the rolling tube is working, there will be a sand bar. A lot of abrasive grains are placed on the sand bar. If sufficient pressure is applied to the abrasive grains, the rolling pipe will rub at a certain speed and then the surface of the workpiece. Such extrusion and hanging side can reduce the surface roughness of the workpiece finely.
There is also the fact that the abrasive grains form a certain trajectory on the surface when the sand bars are running and moving up and down. The cutting speed of the honing pipe is relatively low, which can greatly improve the efficiency of honing.
Rolling tube characteristics
1. Small outer diameter, no weld seam, pressure resistance.
2, high precision can be done in small batches.
3. The cold drawn product has high precision and good surface.
4. The horizontal area is complicated.
5, good performance, metal is dense.
The rolling speed of the rolling tube has little effect on the surface roughness, so we can effectively increase the rolling speed to improve the production efficiency when the operation is performed. The rolling speed should not be too many, and one rolling is performed during the operation. The effect is most significant, so that the roughness can be reduced by 2 to 3. Second, three times.
The amount of feed of the rolling tube should be determined by the diameter of the ball. The smaller the feed amount, the smaller the surface roughness. The optimum feed rate should be determined by experimentation.
