Small-sized industrial CNC precision automated sheet metal bending
machine How to set parameters such as bending angle and pressure according
to the characteristics of the sheet and the bending requirements? First of all, it is necessary to fully understand the
characteristics of the sheet. This includes the material of the
sheet (such as stainless steel, aluminum, carbon steel, etc.),
thickness, hardness and surface treatment. Sheets of different
materials have different yield strengths and ductilities. For thinner sheets, usually smaller pressure and shallower bending
angles are required. For example, a 0.5mm thick aluminum sheet may
only require lower pressure to achieve the required bending angle. Thicker sheets require greater pressure. For example, a 3mm thick
steel sheet may require a significant increase in pressure to
achieve the same bending effect. The hardness of the sheet also affects the parameter setting.
Sheets with higher hardness require greater pressure and possibly
smaller increments in the bending angle. In terms of bending requirements, if an accurate bending angle and
minimal springback are required, higher pressure and more precise
angle control are needed. When actually setting parameters, you can refer to the operation
manual and technical specifications of the bending machine, which
usually provide some recommended parameter ranges for common sheets
and bending requirements. Carry out the initial test bending first and adjust the parameters
according to the test results. For example, if the angle is not
enough after the first bending, appropriately increase the pressure
or bending angle; if there is excessive bending or sheet cracking,
reduce the pressure or bending angle. It is also possible to use computer-aided design (CAD) and
simulation software to predict the bending effect, determine the
approximate parameter range in advance, and then fine-tune it in
actual operation. For example, for a 1.5mm thick stainless steel sheet that needs to
be bent at a 90-degree angle, it is predicted through simulation
software that 5 tons of pressure and an initial bending angle of 45
degrees may be required, and then fine-tuned according to the
effect in actual operation to finally obtain the ideal bending
result. In conclusion, setting parameters such as the bending angle and
pressure according to the characteristics of the sheet and the
bending requirements is a process that requires a combination of
experience and experimentation, and continuous adjustment and
optimization are needed to achieve the best effect.
