Stainless steel punching hole meshes basic information

I have introduced stainless steel wire mesh before, and I will introduce you to the stainless steel punching hole meshes today.

1. The hole diameter of the stainless steel plate punching hole meshes is generally not less than or equal to the plate thickness (according to the minimum hole principle). The distance between the conventional hole and the hole is preferably 1.5 times the thickness of the plate. There are roughly two ways to arrange meshes: straight rows and plum blossoms.

Second, the punching hole meshes opening ratio refers to a ratio between the punching area and the whole plate, and the calculation formula of the normal opening rate of the punching hole meshes is expressed by a percentage. Now let us use the following punching mesh specifications to illustrate: round hole, 2MM aperture, 60 degree misalignment, 4MM center distance, external dimensions 1M X 2M. According to the above information and the following formula, we can get this The punching mesh of the specification has an opening ratio of 23%. That is to say, the sum of the areas of the holes punched out by the punching hole meshes is 0.465 square meters.

Third, how to ensure the flatness of the punching hole meshes

1, related to the material. The degree of deformation of different materials after stamping is different. The degree of deformation of stainless steel is the largest and it is difficult to level. This is because of the rigidity of stainless steel, it has a certain degree of toughness, so it is difficult to reach the leveling after the flattening. The same flatness.2, related to the aperture and the hole pitch. The smaller the hole is, the denser the pitch is, the worse the flatness is. The punching process of the punching needle and the stainless steel plate during the numerical control punching is equivalent to annealing the stainless steel plate, so the plate becomes hard and is not flattened. 3, the impact of flatness is the edge of the board. The greater the margin, the worse the flatness is, especially the larger the opening ratio, the larger the aperture, and the larger the whiteness on the four sides, especially the leveling, even if the leveling is done, the transportation and loading and unloading will be the punching net. Deformed again. In summary, after the punching hole meshes (punching plate, round hole net, sieve plate) is finished, it needs to be leveled. The so-called "leveling" means that the punching plate after the NC punching is restored to its original flat condition by using a leveling machine or the like. Moreover, it is usually necessary to clean the punching plate after leveling, during which lubricant is used for disposal to make the CNC punching plate cleaner. In addition, in order to minimize the various errors that occur in the production process of the punching net, i  introduces how to process, what kind of mold and what kind of method to ensure the flatness of the stamped product before production. In this way, the quality of CNC punching products can be ensured to the greatest extent.
