Concept definition
define
Mesh refers to the different shapes of hole in different materials, so as to adapt to different needs.
The material
Mesh with most of the raw materials are: stainless steel plate, low carbon steel plate, galvanized sheet, PVC plate, cold rolled coil, hot rolled plate, aluminum plate, copper and so on.
species
Mesh design, molding, punching net, heavy mesh, thin mesh, micro hole mesh, wire mesh cutting, laser punching net, etc.
2 pass specifications
Mesh main specifications are rectangular hole, square hole, diamond hole, round hole, slotted hole, hexagonal hole, cross hole, triangle hole, long waist hole, the plum blossom bore holes, scales, patterns, eight net, herringbone hole bore, pentagram, irregular, the drum hole, hole, hole Venetian blinds, etc.
1. The plate thickness of 0.2 mm - 1 mm, length of 20 m
2. The pore size of 1.5 mm to 10 mm
3. A plate thickness of 0.2 mm to 20 mm;Width * length 1.5 m * 5 m or less
4. The pore size of 0.5 mm - 200 mm
3 punching way
Blanking: 1, the same direction of continuous use of rectangular mesh mold overlap processing, can carry on the processing of long hole, trimming, etc.
2, continuous forming: molding processing way bigger than a perforated metal mold size, such as large size blinds, rolled steel, roll the steps such as processing way.
3, eating into: use small circular die with small interval for continuous strike arc processing way.
4, of the continuous cutting direction: using a small mesh mold machining way of big hole.
5, a single shape: according to the mold shape a shallow deep drawing forming processing way.
6, single shot: a single complete punching, including straight line, arc distribution, the circular distribution, grid hole punching.
7, array shape: on the big board processing more than the same or different ways of workpiece machining.
4 defects to correct
(1) punch when eccentric correction: when the anvil surface uneven, punching punch two unequal end face askew and billet heating, produces aperture eccentric.Correct solution immersion method available: operation is the thin side of hole wall into the water, to lower the temperature, and then use the punch hole reaming, one side of the wall thickness due to higher temperature, good plasticity and thinning, make whole forging uniform wall thickness, eccentric is correct.This method is suitable for plastic materials.
(2) when punching blank shape.That punch below metal were crowded around, billet height, diameter, on the face sag, the end face.Gives the size and the billet diameter before punching D0, highly H0 related to the size, and pore diameter d1 D0 the less/d1, it gives the more serious degree.Correct way is: should be controlled D0 / d1 acuity 2.5 ~ 3 as well.If the punch diameter is larger, such as D0 / dl < 2.5, general first blunt holes, then reaming, to achieve the requirements of the aperture.
Five practical use
Mesh can be used through the urban area of highway, railway, subway and other municipal traffic facilities in the environmental noise barrier, wall construction object, generator room, factory workshop, and other noise source acoustic noise reduction with sound-absorbing board can be used in the structure of the ceiling, wall panel sound-absorbing materials;Can be used for building staircases, balcony, environmental protection furniture elegant decorative orifice plate;Can be used to shield of mechanical equipment, speaker net, food, feed, mines with grinding ore sieve, sieve, sieve, h kitchen equipment with stainless steel fruit blue cover, food, fruit tray, such as kitchen utensils and appliances, and shopping malls shelf, decoration exhibition platform, grain ventilation breathable mesh, football field lawn ooze water filter water filter.Mesh is widely used in the electronics industry, such as sound of dust-proof enclosures, as shown in the figure below: product features: paint, easy to processing molding, can absorb or polishing, easy to install, attractive appearance, all kinds of thickness of the plate, a variety of selected aperture and arrangement, good sound-absorbing effect, lighter weight, long service life, precise dimensions Mesh is widely used in chemical machinery, pharmaceutical equipment, food and beverage machinery, cigarette machine, cutter, dry cleaners, ironing table, sound equipment, refrigeration equipment, central air conditioning) speakers, handicraft production, paper making, hydraulic accessories, filtration equipment and so on all walks of life
