For the tolerance of the sieve hole size and hole spacing of the hole analysis. When the perforation is greater than 10 mm, follow the provisions of H10613: When the perforation is less than 3m, follow the provisions of GB/T3512: 5.2 Plate thickness (42)
The plate thickness should be smaller than the original size and spacing of the sieve hole, and can be adjusted according to the requirements of the user. There are other notes. The uniformity of the hole shape before punching depends on the actual pressure used in the dust spraying system and meets the "system pressure". If there are special pressure requirements, one should be obtained before ordering.
5.3 Plate width and plate length (see Figure 2)
The tolerances of the plate width and plate length are given in Table 2. Note: The actual tolerances of the punching material will be greatly reduced during punching. Therefore, the tolerances in the table are not applicable. GB/T19360—2003/S0106301994

According to the thickness of the plate. According to G/T10612 or H/1-0513, the hole size and hole spacing should be measured. It should be carried out on the punching surface. 6.2 Width and length of board [View 2)
Measure the width and length of board with the scale. When the size is less than or equal to 3Tu, it can be measured with a vernier ruler. 6.3 Angles (see Figure
If feasible: Measure the width and length of board according to 5.1 and 5.2, and use the non-right angles to determine the straightness of the board before and after the cut. The parameters can be determined by using a ruler.
6. Unevenness
Place the punched surface of the plate on a flat surface, such as a table top. Use a flexible ruler with a scale of several meters to measure the distance from the highest point of the screen or vertical surface. 7. Irregularity caused by the punching process
7.1 Separation of holes (see 4)
When punching, the material will not start from the back of the hot back. The separation area and size are impossible. No matter how high it is, it will not exceed 1/3 of the plate thickness. The separation area should be proportional to the plate thickness (in accordance with the standard), and will not exceed the basic hole size of F + 0.15. r:7.2 Burrs on holes and burrs on cutting (see 1)
and cutting processes will produce burrs Www.bzxZ.net
When punching, the back of the hand will produce burrs. When cutting, according to different processing procedures, the burrs produced on the punching surface can also be seriously filled with time.
and the burr quantity are not effective. When the hole or the length of the metal screen plate cutting edge is not 1U%, the burr will exceed the value given in Table 6.
can be measured at the hole with a four-degree ruler. The maximum value of the burr height in Table 6
is the nominal thickness.

CB/T19360—2003/TSO1063019947.3 Wave edge (5°)
The stress caused by punching can cause the screen plate to deform and the new space to change its flatness, producing the adjusted "reverse wave edge". When the width of the space on both sides is greater than (5°), the phenomenon is more obvious. The maximum value of the edge deviation should be consistent before calculation. 7.4 Arched edge (arched (see Figure 6)
The hole is then The stress generated during the flattening process will lead to the necessary deformation of the sieve plate, resulting in bending (edge shape/shadow). When the longitudinal edges are not equal and parallel to the punching direction, the phenomenon will increase. The concave shape is defined as the maximum deviation of the edge from a straight line over a certain length. The measurement should be based on the standard scale:
The maximum value allowed for the shape should be obtained before ordering: 7.5 (Figure 7)
The punch may be out of specification during the punching process: some positions cannot be punched. This kind of thing The number of holes missing from the original punching process should be equal to the total number of holes on the sieve plate. When using a multi-function punch, the holes can be punched in the same way. For example, in order to reduce tool wear, the punching machine can be used with a hole spacing of less than 5 mm. In this case, one or more rows of holes will be missing (incomplete) on both sides of the sieve plate.
8 Surface characteristics
8.1 Surface properties
During the punching process, the metal plate should not be damaged by the machine. If this will have a significant impact on the intended use, the purchaser should consult with the manufacturer before delivery. 8.2 Please note
The surface of the gold sieve plate is usually covered with a thick oil film. There should be no excessive moisture after the addition. The degreased gold plate can be shipped under the conditions permitted by the manufacturer after being treated with a solvent or steam. For carbon steel, if there is a post-processing treatment, it is not suitable for acid oil

The length of the metal screen plate roll should be less than mm. In addition to meeting the following requirements, it should also meet the requirements of Section 5. 9.1 Length
The length should be standardized before ordering
9. 2 Width
The tolerance of the plate width should be consistent with the actual tolerance of the punching product of the rolling mill.

The stresses generated by the subsequent flattening process of the hole will lead to the necessary shape of the screen plate, resulting in a bending (the side is parallel to the punching direction). When the longitudinal sides are not equal, the phenomenon is more obvious. The continuous shape is defined as the maximum deviation of the side from a straight line over a length. The measurement should be based on the standard scale:
The maximum value allowed for the shape should be obtained before ordering: 7.5 Missing holes (Figure 7)
The punching process may be out of specification: some positions cannot be punched. The number of holes missing due to this original pressure should be calculated based on the total number of holes on the screen plate. When using a multi-function punch, the holes can be punched according to the type. For example, in order to reduce tool loss, the punching machine should be less than 5mm, and the hole spacing should be different. In this case, the two sides of the screen plate will not be completely covered with one or more rows of missing holes (incomplete).
