5, single forming: a shallow deep drawing process according to the shape of the mold.
6, single punch: single punch, including straight line distribution, circular arc distribution, circular distribution, grid hole punching.
7. Array forming: processing many parts of the same or different workpiece on a large plate.
Edit this Section specification 1. plate thickness 0.2mm-1mm, length 20m
2. aperture 3mm-10mm
3. plate thickness 0.2mm-20mm width * length is less than or equal to 1.5m*5m;
4. aperture 0.25mm-200mm
(1) the correction of eccentricity in the punching hole: the aperture is eccentric when the anvil is not flat, the two ends of the punch are skewed and the blank is heated unevenly. The correction method can be carried out by immersion method: when operating, the thin side of the hole will be immersed into the water to reduce its temperature, and then expand the hole with punch. The wall thickness will be thinner due to the high temperature and good plasticity, so that the wall thickness of the whole forging is uniform, and the eccentricity is corrected. This method is suitable for good plastic materials.
(2) the blank is out of sample when the hole is punched. That is, the metal under the punch is pushed around, the height of the blank is reduced, the diameter is increased, the upper end face is depressed, and the lower end face is raised. The degree of aliasing is related to the size of D0, height H0 and aperture D1 before punching, and the smaller the D0/d1, the more serious the aliasing degree is. The correct approach is: should control D0/d1 more than 2.5~3 as well. If the diameter of the punching hole is larger, such as D0/dl<2.5, the hole is usually washed first, and then the hole is reamed to obtain the required aperture.
Edit this section uses punching net for environment noise control barrier across the city section of highway, railway, subway and other transportation facilities in the building body wall, generator room, factories, and other noise sources of noise with sound absorption board can be used for building the ceiling and wall sound-absorbing ring net, horn net
Sound material, can be used for fine decoration plate building stairs, balcony, tables and chairs can be used for environmental protection, machinery and equipment protection cover, grille gorgeous, food, feed, mine mill sieve, sieve screen, I-beam, stainless steel kitchen equipment, food cover, blue fruit fruit and other kitchen utensils, as well as shopping malls with the network, decoration exhibition shelf, ventilation network for grain depot, the football field lawn water filter water filter. Punching net is widely used in the electronics industry, such as the sound of dust enclosures, as shown below: product characteristics: easy molding, can be painted or polished, easy installation, attractive appearance, various thickness of the sheet, a wide selection of pore size and arrangement, good sound-absorbing effect and lighter weight, long service life, accurate size of mesh is widely used in chemical machinery, pharmaceutical equipment, food and beverage machinery, cigarette machines, harvesters, dry cleaning machines, ironing machine, sound equipment, refrigeration equipment (central air-conditioning) speakers, crafts, paper, hydraulic fittings, filtration equipment and other industries
