The working principle of the bending machine can be summarized as the following key steps:
1. Preparation stage:
– The operator first needs to select the appropriate mold according to the requirements of the workpiece, and place the metal sheet on the work table of the bending machine.
2. Clamping and positioning:
– The press holds the sheet metal firmly on the work table through its clamping device (such as clamping plate). This usually involves the use of electromagnetic forces or other clamping mechanisms to ensure the stability of the sheet during processing.
3. Bending operation:
– Once the plate is clamped, the upper die (also known as the slider) moves downward according to preset parameters (such as bending Angle, depth and speed, etc.), acting together with the lower die on the plate to cause plastic deformation, that is, bending.
– During bending, the hydraulic system provides the required force, while the control system ensures accurate movement and position of the upper die.
4. Completion and Release:
– When the sheet reaches the preset bending shape, the upper die returns to its initial position and the clamping device releases the sheet, thus completing the bending process.
– The operator can then remove the formed workpiece and proceed to the next round of bending operation.
In the entire working principle, it is worth noting that the accuracy, stability and efficiency of the bending machine are affected by a number of factors, including the accuracy of the mechanical transmission, the pressure control of the hydraulic system and the intelligent level of the control system. In addition, different types of bending machines (such as manual bending machines, hydraulic bending machines and CNC bending machines) may differ slightly in their working principles, but generally follow the basic steps above.
In addition, from the technical details:
– The bending machine usually consists of a bracket, a table and a clamping plate, wherein the table is placed on the bracket and is composed of a base and a clamping plate. When used, the wire energizes the coil to generate gravity and realize the clamp between the plate and the base plate.
– In the hydraulic bending machine, it also involves the hydraulic cylinder, hydraulic pump and other parts, by controlling the working pressure of the hydraulic pump and the movement speed of the hydraulic cylinder to achieve the movement control of the workbench and the upper and lower molds.
– Control systems, especially PLC controllers and touch screens, play a key role in the bending process, monitoring and adjusting the position of the table and the upper and lower dies in real time to ensure the accuracy and efficiency of the bending.
