Forging Advanced Technology for Automotive Mining Aerospace
Industries
Aluminum and aluminum alloys are the most widely used non-ferrous
metals.
Precision forging forming technology (net forming) refers to the
forming technology of the forging forming layer of the part, which
only needs a small amount of processing or no processing to meet
the requirements of the part. Precision forging forming technology
is an important part of manufacturing technology and is also a
widely used part manufacturing technology in the automotive,
mining, energy, construction, aviation, aerospace, weapons and
other industries. Precision forging forming technology not only
saves materials and energy, reduces processing technology and
equipment, but also significantly improves productivity and product
quality, reduces production costs, and thus improves the market
competitiveness of products.
According to different forming temperatures, precision forging
processes can be divided into hot precision forging, cold precision
forging, warm precision forging, composite precision forging,
isothermal precision forging, etc.
1. Hot precision forging process? The precision forging process
with a forging temperature higher than the recrystallization
temperature is called hot precision forging. Hot precision forging
materials have low deformation resistance, good plasticity, and are
easy to form die forging.
2. Cold precision forging process Cold precision forging process is
a precision forging process at room temperature. The cold precision
forging process has the following characteristics: it is easy to
control the shape and size of the workpiece and avoid errors caused
by high temperature; the workpiece has high strength and precision
and good surface quality.
3. Warm precision forging process The warm precision forging
process is a precision forging process carried out at an
appropriate temperature under the recrystallization temperature.
The warm forging precision forming technology not only breaks
through the limitations of large deformation resistance and not too
complex part shape in cold forging, and the need to increase the
intermediate heat treatment and surface treatment steps, but also
overcomes the problem of reduced surface quality and dimensional
accuracy due to strong oxidation in hot forging.
4. Composite precision forging process With the increasing
complexity of precision forging workpieces and the improvement of
precision requirements, simple cold forging processes cannot meet
the requirements.
5. Isothermal precision forging process Isothermal precision
forging process refers to the forming of billets at constant
temperature. Isothermal die forging is often used for the precision
forming of difficult-to-deform materials in the aerospace industry
such as titanium alloys, aluminum alloys, and magnesium alloys. In
recent years, it has also been used for the precision forming of
non-ferrous metals in the automotive and machinery industries.
Isothermal forging is mainly used for metal materials with a narrow
forging temperature, especially titanium alloys that are very
sensitive to deformation temperature.
① Produce precision die forgings and precision die forgings for
finished parts.
② The production of precision die forgings, the main part of
precision forgings, saves cutting processing, and some parts still
require a small amount of cutting processing.
Advantages of precision die forging of aluminum alloy forgings
1. Greatly reduce the cost of product parts
Aluminum alloy forgings have small machining allowances, small
tolerances, and small surface roughness values. Machining can
partially or completely replace parts, save materials and machining
time, and improve labor productivity.
2. Improve the mechanical properties and service life of products
The metal streamlines of aluminum alloy forgings are not cut off,
and the distribution of streamlines is more reasonable. The
strength of forgings is about 20% of cutting processing, with
strong stress resistance, strong corrosion resistance, and long
service life.
3. Suitable for parts with complex shapes, high performance, and
expensive materials
These parts that are difficult to machine, consume a lot, are
expensive, and precision die forging has obvious saving effects,
such as gears, toothed parts, blades, aviation parts, electrical
parts, etc.
4. There must be an appropriate batch
Precision forging is not economical in any case. Consider the
batch, performance requirements, comprehensive cost and economic
benefits of product production. The larger the batch, the better
the benefit.
