Application of KTF linear displacement sensor in hydraulic press
KTF slider linear displacement sensor is widely used in various hydraulic presses for forging, stamping and composite material forming because of its compact rodless structure and flexible installation. It is the core position detection component of hydraulic closed-loop control system. The sensor has a measuring range of 50–2500mm, which is suitable for the long-stroke reciprocating working condition of hydraulic press slide block. The linear accuracy can reach 0.05% FS, and the resolution is better than 0.01mm It can collect the lifting displacement data of the piston rod of the main cylinder in real time, convert the standard voltage or 4–20ma electric signal and send it back to the PLC control system.
In the actual assembly, the external bracket is used for fixing, and there is no need to open holes in the cylinder body of the oil cylinder, which is suitable for the narrow assembly space of the hydraulic press. The universal slider structure can offset the lateral deviation caused by the vibration of the equipment and adapt to the instantaneous impact working condition of stamping. IP54 protective shell can withstand the oil stain and dust intrusion of equipment, and its cycle life exceeds 50 million times, which meets the requirements of high-frequency continuous production of hydraulic press.
On the control level, the fast and slow switching of slider, limit braking and multi-cylinder synchronous regulation are realized by real-time displacement feedback: the pressing process accurately locks the pressing depth to ensure the uniform forming size of workpiece; The extreme value of travel automatically outputs the stop signal, so as to prevent the over-travel die-impact fault; Synchronous correction of multi-cylinder feed deviation, improving the problem of unbalanced load and uneven force. Relying on KTF precise measurement and control, the forming yield of hydraulic press is significantly improved, and the equipment failure rate and die loss are simultaneously reduced, which helps the automatic upgrading of hydraulic equipment.
