How does hydraulic alligator shear control the cutting lengt
Hydraulic alligator shears are mainly used for scrap metal recycling. The processing raw materials are irregular and different in length. The large hydraulic gantry shears have a hydraulic press platform for the feed, how is the discharge shear length controlled?The switch on the hydraulic alligator shear is an azimuth switch that can be operated without mechanical contact with moving parts. When a metal object is close to the sensing surface of the switch to the action distance, it does not require mechanical contact and any pressure to make the switch act. Then drive communication or DC electrical appliances or supply control signals to the computer device. Working principle of proximity switch on hydraulic alligator shearThe hydraulic alligator shear is equipped with an inductive proximity switch. It is an azimuth sensor with a switching output. It is composed of an LC high-frequency vibrator and an amplification processing circuit. When a metal object is approached to this vibration induction head that can generate an electromagnetic field, the object is made Vortex occurs inside. This eddy current counteracts the proximity switch, so that the vibration of the proximity switch can be attenuated, and the parameters of the internal circuit change, thereby identifying whether there is a metal object approaching, and then controlling the switch on or off. The objects that can be detected by this proximity switch must be metal objects. Its operating principle is shown. When the measured metal object is far away from the induction magnetic tank, the high-frequency signal of the high-frequency vibration circuit enters the signal processing circuit through the shaping detection. The signal after the signal processing circuit makes the switch output a condition (for example: open); when the measured metal object is close to the induction magnetic tank, the vibration of the high-frequency vibration circuit can be attenuated, and the relatively low-frequency signal output by the high-frequency vibration circuit passes The shaping detection enters the signal processing circuit, and the signal after the signal processing circuit causes the switch to output another condition (for example: closed); this is the operation process of the proximity switch. The application of the proximity switch may be closed or closed to achieve drive communication or DC power. Or supply control signals to the computer device. The hydraulic alligator shear also realizes the cutting length of the material through the proximity of the switch and the sensor.
