What is punching? What is precision stamping and ordinary punching: Punching is
the use of conventional or special punching equipment, power, so that the sheet
directly in the mold by the deformation force and deformation, resulting in a
certain shape, size and performance of the production of parts technology. Sheet
metal, mold and equipment are three elements of stamping. Stamping is a cold
deformation of metal processing methods. Therefore, it is called cold stamping
or sheet metal stamping, referred to as stamping.
It is a metal plastic
processing (or pressure processing) one of the main methods, but also under the
material forming engineering technology. Stamping used by the stamping die
known as mold, referred to as die. Die is the material (metal or non-metallic)
batch processing into the required pieces of special tools. Die in the stamping
is essential, there is no need to meet the requirements of the die, punching
production is difficult to carry out; there is no advanced die, advanced
stamping process can not be achieved. Stamping process and mold, stamping
equipment and stamping materials constitute the three elements of stamping, only
they can be drawn with each other stamping parts. Compared with other methods
of machining and plastic processing, stamping has many unique advantages in
terms of technology as well as economy. Mainly as follows. (1) stamping
processing of high production efficiency, and easy to operate, easy to achieve
mechanization and automation. This is because the stamping is to rely on
stamping die and stamping equipment to complete the processing, general presses
the number of strokes per minute up to dozens of times, high-speed pressure to
hundreds of times per minute or even more than a thousand times, and each stroke
stamping May get a punch. (2) stamping due to the mold to ensure the stamping
parts of the size and shape accuracy, and generally do not damage the surface
quality of stamping parts, and die life is generally longer, so the quality of
stamping stability, interchangeability, with 'exactly the same' Characteristics.
(3) stamping can be processed out of the larger size range, the shape of the
more complex parts, such as a small stopwatch to the clock, large automotive
stringers, panels, etc., plus stamping material cold deformation hardening
effect, stamping strength and Stiffness are higher. (4) stamping is generally
not the formation of chip debris, material consumption less, and no other
heating equipment, which is a province of material, energy-saving processing
methods, stamping parts of the lower cost.
As the stamping has such
advantages, stamping processing in a wide range of national economy in a wide
range of applications. For example, in the aerospace, aviation, military,
machinery, agricultural machinery, electronics, information, railway,
telecommunications, transportation, chemical, medical equipment, household
appliances and light industry and other departments have stamping processing.
Not only the entire industry have used it, and each person directly with the
stamping products in contact. Like aircraft, trains, cars, tractors there are
many large, medium and small stamping parts. Car body, frame and rims and other
parts are stamping out. According to the survey statistics, bicycles, sewing
machines, watches, 80% of stamping parts; TV, tape recorders, camcorders, there
are 90% of stamping parts; there are food metal shell how to
do punch quilting, steel boiler, enamel bowl and stainless steel tableware,
All using the stamping die processing products; even the computer hardware is
also the lack of stamping parts. However, the stamping die used in general
have a special nature, and sometimes a number of complex parts need to die
processing to shape, and the mold manufacturing high precision, high technical
requirements, is a technology-intensive products. Therefore, only in the
stamping parts production of large quantities of the case, the advantages of
stamping can be fully reflected in order to obtain better economic benefits.
Precision punch with what characteristics In some metal sheet metal processing
pack a punch zombies, precision punch
has a wide range of applications, such as computers, home appliances, vehicles
and some other products processing, in the next content will introduce the main
features of precision punching what. The first point, since it has become a
precision punch, then the high-precision certainly is not missing features, and
precision punch frame is usually used steel, with high rigidity, is a high
rigidity, high precision equipment . Second, the precision punch press
transmission center can be consistent with the overall center of the machine, so
the precision punch to the center of gravity can be more balanced, thus ensuring
the accuracy and stability of stamping. Third, the precision punch is an
environmentally friendly energy-saving machines, not only the appearance is
relatively beautiful, but also can effectively reduce the noise issued, energy
consumption is relatively small. The above is some of the main features of
precision punching machine, can be seen from the above content, precision punch
design concept is more advanced, not only has better machine performance, and
reflects the environmental protection, energy conservation awareness, is in line
with modern society Concept of machinery and equipment.
Of course,
stamping there are some problems and shortcomings. Mainly in the stamping
process noise and vibration generated two kinds of pollution, and the operator's
safety accidents occur. However, these problems are not entirely due to stamping
process and die itself brought, but mainly due to the traditional stamping
equipment and backward manual operation caused. With the progress of science and
technology christmas
punch quilt pattern, especially the development of computer technology, with
the progress of electromechanical integration technology, these problems will be
solved as soon as possible two perfect. Precision stamping generally can be
called a molding, to minimize stamping after processing. Ordinary stamping is
stamping, still need post-processing.
