The forming of the sieve plate is a very important part of the process of producing holes. The forming of the sieve plate is affected by many factors. The first thing to pay attention to is the influence of the nature of the material on the selection of the sieve plate. It is necessary to determine the size of the sieve hole, and set a reasonable sieve hole according to the particle size of the sieve and the nature of the sieve material. Secondly, the factors that affect the forming of the sieve plate include the adjustment method of the sieve plate grinding tool and the guide bending mold. The relative position of the upper and lower molds is determined entirely by the guiding device. If there is no guiding device, the relative position on the press is generally used to adjust the length of the connecting rod of the press.
When the sieve plate becomes habitual, it is also easy to block the sieve plate. Therefore, you must pay attention to the direction of the aperture during processing. The small holes should face up and the big holes face down. If clogging occurs, it is generally necessary to rectify the process, and add an in-grind hoist to allow finer-grained materials to directly enter the mill. Must pay attention to these aspects in the process of processing.
only by playing the biggest role of the sieve, can the sieve play a big role. So we must pay attention to the following points:
1. The first is to increase the pattern on the surface of the sieve plate, so that if there are slight scratches and small area indentations, it is not obvious.
2. Secondly, reduce the shrinkage of the metal roofing material of the sieve plate. For large-area decorative panels, it is difficult to make the plane completely flat even after stretching and straightening or tensioning and straightening, so the metal roofing material will shrink.
