The main specifications of punching nets include rectangular holes, square holes, diamond holes, round holes, oblong holes, hexagonal holes, cross holes, triangular holes, long waist holes, plum blossom holes, fish scale holes, pattern holes, eight-character nets, and herringbone holes. Holes, five-pointed star-shaped holes, irregular holes, bulging holes, special-shaped holes, louver holes, etc.
1. The thickness of the rolled plate is 0.2mm-1mm, and the length is 20m.
2. Hole diameter 1.5mm-10mm.
3. The thickness of the sheet is 0.2mm-20mm; width*length≤1.5m*5m.
4. Aperture diameter 0.5mm-200mm.
Punching method
1. Continuous punching in the same direction: Using the partially overlapping processing method of the rectangular punching mesh mold, long holes, trimming, etc. can be processed.
2. Continuous forming: Forming processing methods that are larger than the punching mesh mold, such as large-size blinds, rolled ribs, rolled steps and other processing methods.
3. Nibbling: A processing method that uses a small round die to continuously punch arc shapes in smaller steps.
4. Multi-directional continuous punching: a processing method that uses a small punching mesh mold to process large holes.
5. Single forming: a processing method of shallow drawing and forming according to the shape of the mold.
6. Single punching: Complete punching in a single pass, including punching of linear distribution, arc distribution, circumferential distribution, and grid holes.
7. Array forming: a processing method for processing multiple identical or different workpieces on a large plate [1].
Defect correction
(1) Correction of eccentricity during punching: During punching, due to uneven anvil surface, skewed end surfaces of the punch and uneven heating of the blank, aperture eccentricity will occur. The correction method can be carried out by immersion method: during operation, the thin side of the hole wall is immersed in water to reduce the temperature, and then a punch is used to expand the hole. The thick side of the wall becomes thinner due to higher temperature and good plasticity, making the entire forging wall The thickness is uniform and the eccentricity is corrected. This method is suitable for materials with good plasticity.
(2) The blank is out of shape during punching. That is, the metal under the punch is squeezed to all sides, the height of the blank is reduced, the diameter is increased, the upper end face is sunken, and the lower end face is convex. The degree of aliasing is related to the diameter D0, height H0 and hole diameter d1 of the blank before punching. The smaller D0/d1, the more serious the degree of aliasing. The correction method is: D0/d1 should be controlled to be ≥2.5~3. If the diameter of the hole to be punched is large, such as when D0/dl<2.5, the small hole is usually punched first and then expanded to obtain the required hole diameter.
Zhengde Punching mesh/Perforated mesh refers to punching holes of different shapes on the same material. Common raw materials for perforated mesh include cold-rolled steel coils, stainless steel, galvanized steel coils, aluminum coils, copper coils, etc. Perforated mesh is suitable for environmental noise control, sound-absorbing panels around buildings, generator rooms, etc., and can also be used as speaker grilles.
The perforated net has a lot of loss in the production process, and the production process is complicated, mainly because it has a lot of hole-like structures, but this variety of shapes adds a colorful visual impact to the perforated net. Make the decoration effect of the punching net more obvious. At the same time, the perforated mesh has good air permeability and a wider range of use.
Specification of punching mesh plate: aperture 0.2-20mm, plate thickness 0.25-20mm
Iron plate punching mesh is divided by thickness: 1, thin plate, 2, medium plate, 3, thick plate, 4, extra thick plate
Iron plate punching mesh is divided into: 1. Hot rolled steel plate, 2. Cold rolled steel plate material, 3. Stainless steel plate 302, 304, 316, 304L, 316L, 4. Aluminum plate, and 5. Copper plate.

Automated manufacturing
The automatic production line for high-speed punching of metal plates in the workshop of the punching mesh manufacturer is divided into two parts: the stamping section, the centering leveling section, and the winding section. The production line mainly completes the punching and coiling functions of metal coils. The metal coils go through uncoiling, feeding, punching, looping (buffering), and flattening, tensioning, and winding after punching. Complete the whole process of production. At the same time, in order to improve the quality of the coiling, it is also equipped with a rectifying device for coiling and a magnetic powder brake for generating tension.
Diversified pore types
1. 60° round hole: The 60° plum blossom is placed with its natural high strength.

6. Slotted holes: Straight-lined slotted holes are mainly used in vibrating screens and filters.
7. Hexagonal hole: It can greatly improve the opening rate.
Other favorite hole patterns can be customized arbitrarily.
