Description
Concept
Definition: punching network is marked with the different shapes of
the hole, to adapt to different needs in different materials.
Material: the punching mesh with the raw materials are mostly: low
carbon steel plate stainless steel plate galvanized sheet, hot
rolled sheet, cold rolled coils, PVC board, aluminum sheet copper
plate.
Types: pattern punching, forming perforated metal mesh, heavy
punching, special thin metal mesh, microporous perforated metal
mesh, perforated metal mesh wire cutting, laser punching net.
Perforated metal mesh specifications rectangular hole, square hole,
diamond hole, round hole, a long hole, hexagonal hole, cross hole,
triangle hole, long waist hole, the plum blossom hole, scale hole
pattern holes, horoscopes network, the word holes, pentagram hole,
irregular holes from the drum hole, Hole, venetian hole.
Perforated metal mesh perforated metal mesh
1, the same direction as the continuous blanking: partly
overlapping rectangular perforated metal mesh mold processing,
processing of long holes, trimming.
Continuous forming: the molding forming mold size than punching
net, such as large-size shutters, roll tendons and roll stairs
processing methods.
3 to nibble at a small step away from the continuous punching arc
processing: Use small round mold.
4 multi-directional continuous blanking: Use small perforated metal
mesh the mold processing large hole processing.
5, a single shape: the shape of the mold once shallow pull deep
molding processing.
6, a single red: single punching, including the the linear arc
distribution distribution circumference, grid hole punching.
7, the array forming processing multiple items of the same or
different workpieces way: in the big boards.
Specification
A coil thickness 0.2mm*1mm, and a length of *0m
2. Aperture 3mm**0mm
Zhang plate thickness 0.2mm**0mm; width * length ≤ 1.5m * 5m
4. Aperture 0.*5mm***0mm
The punching mesh punching defect how to correct
(1) punching generated when the eccentric correction: Punching the
anvil surface uneven, both ends of the punch surface skew blank
uneven heating will produce aperture eccentric. Correction methods
available soaking method: the operation hole wall thin side
immersed in water, its temperature is reduced, and then punch
reaming, the wall thickness of the side due to the high
temperature, good plasticity thinned, so that the whole forging
wall uniform thickness, eccentricity is corrected. This method
applies to a material with good ductility.
(2) punching blank aliasing. I.e. below the punch the metal being
squeezed height is reduced to four weeks, the blank diameter is
increased, the upper end surface depressions, the lower end face of
the projection. Aliasing magnitude of punching former blank
diameter D0 height H0 and aperture d1 is related to the size of the
smaller, D0/d1 aliasing the more serious. Correction: control D0/d1
≥ 2.5 ~ 3 as well. If punching larger diameter, D0/dl <2.5,
generally the first punch hole, and then proceed to the
counterbore, in order to obtain the desired pore size.
Use
Perforated metal mesh can be used across the city lots of highway,
railway, subway and other transportation municipal facilities,
environmental noise control barriers, architectural objects, walls,
generator room, factory buildings, and other noise sound source of
acoustic noise absorbing panels ceiling, wall of sound-absorbing
material can be used for buildings, beautifully decorated plate for
building stairs, balconies, environmental tables and chairs, the
shield can be used for mechanical equipment, the ornate speaker
cover, food, feed, mining with mill sieve, griddle, the word
screen, kitchen equipment, stainless steel fruit basket, food
cover, fruit and other kitchen utensils, as well as shopping malls
shelves network decorative exhibition units, grain storage with
breathable mesh ventilation, soccer field lawn seepage water
treatment filters. • Easy to install • striking appearance •
various thickness perforated metal mesh is also widely used in the
electronics industry, such as sound and dust enclosures, as shown
below: Product Features: • easy processing • painting or polishing
pore size and arrangement of plates • Multiple choice • Excellent
sound effects • light weight • longer life • exact dimensions of
perforated metal mesh also widely used in chemical machinery,
pharmaceutical equipment, food and beverage machinery, cigarette
machinery, harvesters, dry cleaning machine, ironing table,
silencer equipment, refrigeration equipment (central air
conditioning) speakers, craft-making, papermaking, hydraulic
fittings, filtration equipment and other industries.
