Electronically controlled hydraulic folding machine


The hydraulic mechanical folding machine is a versatile and advanced piece of equipment that combines the strengths of both mechanical and hydraulic systems. It excels in maintaining parallelism, controlling pressure tonnage, and offering variable stroke capabilities. This makes it highly suitable for precision bending operations in various industrial applications.
The machine's slide is driven by a hydraulic system, allowing for fast approach, slow bending, and precise control over the pressure applied during the forming process. The slide is connected to the frame via a robust pivot mechanism, ensuring smooth and parallel movement without the need for complicated and unreliable cylinder balancing systems.
In contrast, the toggle-type folding machine relies on a mechanical linkage system to maintain parallelism. This design not only ensures stability but also allows a smaller cylinder to generate significant force, reducing costs while maintaining high performance.
The electric control system enhances the functionality of the hydraulic folding machine, turning it into a reliable and efficient tool for precision manufacturing. It simplifies adjustments, improves operational efficiency, and ensures consistent quality in production.
The electronic control flap shown in the diagram replaces traditional relays and limit switches with an integrated switch that offers faster response times and greater reliability. Modern electronically controlled folding machines are often equipped with CNC (Computer Numerical Control) systems, which provide exceptional accuracy and speed in operation.
One of the key advantages of the electronically controlled folding machine is its ability to position the slide precisely based on input data, ensuring a high level of parallelism and accurate bending angles. This feature is essential for producing high-quality components in industries such as automotive, aerospace, and metal fabrication.
The machine is equipped with scanning devices mounted on both ends of the body, covering the area around the mold. These scanning heads are attached to the slider and move vertically as the slide moves up and down. They continuously monitor the environment and send real-time feedback to the control system.
When the scanning head detects an obstacle or reaches a specific point, it sends a signal to the hydraulic valve, causing the slide to stop immediately. This special valve is controlled by the system and responds with high sensitivity, ensuring safe and precise operation.
The system measures and controls the distance between the slide and the worktable, independent of any frame deflection. This capability allows for accurate measurement and control of the bending depth, improving overall product consistency.
Because the mechanical linkage ensures proper alignment, each sheet bending machine only needs one scanning head, which reduces electrical costs and simplifies the system. This design not only improves efficiency but also enhances the machine's reliability and ease of maintenance.
