According to the three-dimensional solid model developed and designed, the finite element dynamic model for calculation is established. The model considers the main components on the force transmission connection. The force is transmitted to the support through the connecting parts, and then the strength analysis of the support is carried out.Accuracy requirements: the stable bed structure, precise component processing and strict assembly process ensure the accurate angle and straightness of the bending center height. The angle is guaranteed to be within ± 0.5 degrees and the size is guaranteed to be within ± 0.05mm.

According to the results of finite element analysis of the frame, Q345 steel is selected as the material of the bending center; Carbon dioxide shielded welding is adopted for integral welding; Conduct tempering treatment to eliminate the stress caused by welding; So as to ensure the accuracy, stability and high rigidity of the equipment for long-term operation. At present, the domestic equipment with low price is connected by two casting bodies with screws. Its defect is that the quality of domestic cast iron can not be guaranteed, and the screw connected bed can not guarantee the subsequent accuracy and stability under the influence of bending pressure. Therefore, our design structure is much higher than the split casting connected bed of domestic products. The cost of welding, tempering, processing and assembly is more than two or three times higher. Due to the slow processing speed, the strength analysis can be attributed to static problems. The pressing load of the plate is 100 tons and the bending load of the cutter head in the vertical direction is 70 tons. The deformation results are shown in the figure below. The maximum deformation occurs at the top of the support, and the maximum deformation is 0.3mm.

Static analysis results:

From the stress nephogram, it can be found that the maximum stress appears at the top of the side plate, and the maximum stress is 97mpa


Bending unit:

Bending efficiency: 0.2 seconds / bending. The bending efficiency is 30% – 40% higher than that of domestic equipment. For example, the fastest bending of door panels with 8 bends takes less than 21 seconds, and most domestic equipment takes less than 30 seconds.

The power driving part of the bending unit is driven by servo motor without the participation of hydraulic system, which has great advantages in reducing component wear and transmission efficiency, and is in line with the energy-saving and environmental protection policy advocated by the state.

According to the setting of plate information, the system automatically calculates the position of upper pressing knife 3, controls the distance between upper pressing knife 3 and lower pressing knife 4, and fixes the plate; According to the system setting, whether this bending is upward or downward, control the lower bending knife 2 or the upper bending knife 1 to move quickly to the bending position; According to the different setting angles, the patented angle calculation formula controls the bending knife to move to the calculation position to complete the bending.

According to different bending methods, it can be divided into angle bending, large arc bending, flattening bending, etc. among them, angle bending is also divided into upward bending and downward bending.

Universal tool library

HMBC full servo multilateral bending center is equipped with universal tool library, so that a series of bending with different plate lengths can be completed through a set of tool.

Before bending, the automatic tool change system can quickly and accurately move to the set position according to the set length of the plate, and there is no need to change the mold manually, so as to improve the productivity.

The automatic tool change system can provide higher flexibility, meet the needs of inner folding and quadrilateral, and can meet the bending requirements of any bending length.

Upper press material : a part to be used in all bending processes
