In sheet metal fabrication, processing technology is an important link to
guide sheet metal processing. The sheet metal production process is the
guideline, which is the specification of the parts production process.
Therefore, reasonable and standard processing technology is an important
guarantee to improve the quality of sheet metal processing. The processing
methods of sheet metal parts have been proved to be mainly stamping, stretching,
bending, and surface treatment.
Sheet metal fabrication is a common processing method in industrial
production. The processing technology of sheet metal parts is to form sheet
metal parts by hand or by stamping with abrasive tools to form a certain shape
and size. It can form more complex parts by welding or machining.
In the production process of sheet metal parts, technology plays an important
role in guiding the processing of sheet metal parts. Therefore, the standard and
reasonable processing technology is the key to improving the processing quality
of sheet metal parts, but also the key to ensuring the quality of products.
For a sheet metal part, the sheet metal part has a cylindrical opening with a
diameter equal to the diameter of the shaft part and the cylindrical rivet part
has been transformed into a rivet roll connecting the lower part of the sheet
metal part. The trapezoidal hole is used in the processing of sheet metal parts.
The larger aperture of the trapezoidal hole can accommodate the riveted edge.
For thick plate gold parts, the use of tapered holes, through tapered rivet
crimped into the tapered reamed hole, can make the plate gold parts improve.
Maybe you don't know, that there is a lot of plate processing in real life,
such as car shells, computer shells, air conditioning shells, kitchenware,
mobile phone plate parts, and so on. Find the common features of these products:
a sheet of metal can be folded or stamped, then processed by sanding, polishing,
deburring, etc., and sold to the market. In life, you may find that many things
are the same.
Sheet metal fabrication method
Blanking is to cut the material into the desired shape according to the
unfolding. There are many cutting methods, according to the type of machine tool
and working principle can be divided into shear, punch cutting, and laser
1.1 Cutting -- cutting the desired shape with a cutting machine. The
precision can reach 0.2mm. It is mainly used for cutting material or cutting
1.2 Blanking and shearing -- blanking with CNC or ordinary punch. The
accuracy of the two feeding methods can reach 0.1mm, but the former will have a
cutting mark, the efficiency is relatively low, the latter is high efficiency,
but the single cost is high, suitable for mass production.
1.3 Laser cutting -- Laser cutting equipment is used to continuously cut
sheets to achieve the desired shape of the material. It is characterized by high
precision, very complex shape, but relatively high processing cost.
