Electronically controlled hydraulic folding machine

The structure of the hydraulic mechanical folding machine. It combines the advantages of mechanical and hydraulic folding machines, especially in parallelism, pressure tonnage control and variable stroke mechanisms.
The hydraulic mechanical folding machine's slide is operated by a hydraulic system with fast approach, slow bending and control of pressure tonnage. The slider is attached to the frame by a sturdy pivot structure that maintains the parallelism of its up and down motion. There is no longer a need to install a complex and unsatisfactory cylinder balancing system.
The structure of the toggle-type folding machine maintains the parallelism of the slider by the mechanical device, and the linkage structure can also strongly drive the slider to generate a sufficiently large working pressure with a cylinder of a smaller specification, thereby saving cost.
The electric controller makes the hydraulic folding machine a precision processing equipment with good reliability, simple adjustment and high production efficiency.
The figure shows the structure of the electronic control flap. Its integral switch replaces the relay and limit switch with the sensitivity of its transient response and the reliability of the alternate control. On the latest electronically controlled folding machines, the control mechanism has been matched to CNC (computer numerical control) systems with extremely high precision and fast movement speed.
The main feature of the electronically controlled folding machine is that it can manipulate the slider positioning by means of input data, so as to achieve a high degree of parallelism to ensure an accurate bending angle.
The system has a scanning device mounted on both ends of the folding machine body, and its scanning range is the area around the mold. These scan heads consist of an electronic controller attached to the slider and move up and down as they slide.
When the scanning head is working, the signal is transmitted to the hydraulic valve through a device, and the sliding will immediately stop running. This valve is a special structure, operated by the controller, and the action response is extremely sensitive.
This system measures and controls the distance between the slide and the table. When working, it is not affected by the deflection of the frame, so it can achieve accurate measurement and control of the bending depth.
Since the mechanical linkage of the hydraulic mechanical folding machine slider provides a correct mode, only one scanning head is required on each sheet bending machine, thus reducing the cost of the electrical appliance.
