The relationship between the tonnage of the plate press brake bending machine and the thickness of the folded plate is the basis for selecting the plate press brake bending machine correctly. If the relationship between these two parameters is unclear, the result is that either the purchased plate press brake bending machine cannot be folded, or the large tonnage cannot be used at all. Both of these situations are a great waste for the manufacturer. Buying a small one cannot be used, buying a large one wastes resources and funds, and the expected cost cannot be recovered within the expected period.
So, how to calculate the relationship between the tonnage of the plate press brake bending machine and the thickness of the bent plate? Below, I will explain it based on the knowledge I have learned, and also help myself increase my memory. There is an industry-wide formula for the relationship between the tonnage of the plate press brake bending machine and the thickness of the bent plate: P=650 * S * L/V
Among them: P – nominal force of the plate press brake bending machine (KN)
S – thickness of folded plate (mm)
L – width of folded plate (m)
V – Width of lower mold opening (mm)
Among the above data, only the opening width V of the lower mold is uncertain (the opening width here is calculated based on the mold folded at a 90 ° angle, and the smaller the folded angle, the larger the required tonnage). According to industry experience, generally the opening width V of the lower mold is (8-10) times the thickness S of the folded plate, so users must know the thickness and width of the plate they want to fold, so calculating the tonnage of the plate press brake bending machine is not a problem.
How to choose and purchase a suitable CNC plate press brake bending machine needs to consider the following factors:
- Calculate how many tons of CNC plate press brake bending machine need to be purchased based on the material and thickness of the metal sheet to be processed and bent. The tons here refer to the maximum pressure of the plate press brake bending machine, not the weight of the CNC plate press brake bending machine;
- The width of the blade surface of the plate press brake bending machine (determined based on the length of the plate), the depth of the throat, and the distance between the columns;
- Whether to choose an electro-hydraulic synchronous CNC plate press brake bending machine or a torsion axis synchronous plate press brake bending machine also needs to be considered. The electro-hydraulic synchronous type of plate press brake bending machine can be more intelligent and fully automated, but the price is higher. The torsion axis synchronous type of plate press brake bending machine is cheaper;
- There are many types of electro-hydraulic synchronous plate press brake bending machine, which can be customized according to the requirements of processing workpiece, such as the number of shafts, compensation type, laser testing, safety protection (laser protection or light curtain protection), etc.
