Material
Most of the raw materials used for punching mesh include: stainless steel plate, low carbon steel plate, galvanized plate, steel plate, cold rolled coil, hot rolled plate, aluminum plate, copper plate, etc.
Category
Patterned punching mesh, formed punching mesh, heavy-duty punching mesh, extra-thin punching mesh, micro-hole punching mesh, line-cut punching mesh, laser punching mesh, etc.
Hole type specifications
The main specifications of punching mesh include rectangular holes, square holes, diamond holes, round holes, oblong holes, hexagonal holes, cross holes, triangular holes, elongated waist holes, plum blossom holes, Fish scale holes, pattern holes, eight-character mesh, herringbone holes, five-pointed star holes, irregular holes, drum holes, special-shaped holes, louver holes, etc.

3 punching method
, same Continuous punching in the direction: Using the partially overlapping processing method of the rectangular punching mesh mold, long holes, trimming, etc. can be processed.
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.
Nibbling: A processing method that uses a small round die to continuously punch arc shapes in smaller steps.
. Multi-directional continuous punching: a processing method that uses a small punching mesh mold to process large holes.
. Single forming: a processing method of shallow drawing and forming according to the shape of the mold.
. Single punching: Punching is completed in a single pass, including punching of linear distribution, arc distribution, circumferential distribution, and grid holes.
Array forming: Processing of multiple identical or different workpieces on a large plate.
Correction of defects
Correction of eccentricity during punching: During punching, due to uneven anvil surface, skewed ends of the punch and uneven heating of the blank, hole diameter 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.
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, height and hole diameter of the blank before punching. The smaller / is, the more serious the degree of aliasing is. The corrective method is: control /. ~3 is good. If the diameter of the hole to be punched is large, such as /., usually the small hole is punched first, and then the hole is expanded to obtain the required hole diameter.
Practical uses
Perforated mesh can be used as environmentally friendly noise control barriers in highways, railways, subways and other transportation and municipal facilities that pass through urban areas, building walls, generator rooms, factory buildings, and other noise The source's sound-absorbing panels for sound insulation and noise reduction can be used as sound-absorbing materials for building ceilings and wall panels, can be used as exquisite decorative perforated panels for building stairs, balconies, and environmentally friendly tables and chairs, and can be used as protective covers for mechanical equipment. Speaker grilles, grinding sieves, mine sieves, I-shaped sieves for grain, feed, and mines, stainless steel fruit baskets, food covers, fruit plates and other kitchen utensils for kitchen equipment, as well as shelf nets for shopping malls, decorative exhibition stands, and grain depots. Ventilation and breathable mesh, football field lawn water seepage filter. Perforated mesh is also widely used in the electronics industry, such as audio dust-proof soundproof covers, etc. Product features: easy to process and shape, can be painted or polished, easy to install, eye-catching appearance, various thicknesses of plates, multiple choices of apertures and arrangements, good The sound-absorbing effect is lighter, the weight is longer, the service life is precise, and the perforated mesh with precise dimensions is also widely used in chemical machinery, pharmaceutical equipment, food and beverage machinery, cigarette machinery, harvesters, dry cleaning machines, ironing tables, silencers, and refrigeration equipment ( Central air conditioning) speakers, handicraft production, papermaking, hydraulic accessories, filtration equipment and other industries.
