FET-55H Metal Automotive Parts Fastener Crack Automatic Eddy Current Detector

FET-55HAutomatic eddy current inspection machine for metal automotive parts fasteners cracks

Instrument Introduction:
    The激励coil induces magnetic flux in the material being tested. The detected coil receives an induced electromotive force (EMF) that is related to the shape and size of the material's hysteresis loop. When a sine wave excitation voltage is used to induce magnetic flux, the resulting induced EMF is also sinusoidal, typically including the fundamental frequency. By measuring the fundamental component of the induced EMF in the detection coil, the characteristics such as cracks and heat treatment status of the measured object can be detected, thereby achieving the inspection of material properties, hardness, and quenching cracks.

Key Features:
    This equipment features2A channel, equipped with a fully automatic machine for the hardness, material, and crack detection of fasteners for metal automotive parts, such as steel, using automatic eddy current testing. This channel also includes sorting. Additionally, another independent manual channel is provided for the sorting and detection of bolt quenching cracks and forging cracks.
    Automatic channel process: Bolts are sorted by vibration hopper and then slide into the feeding channel.2An interactive cylinder sorts and steps up the materials sequentially, which then fall into the detection positioning chain, triggering a photoelectric signal. The stepping motor drives the chain to rotate and step through the probes for detection. After completion of the detection, during the unloading and flipping process, if the material is qualified, the detection samples are accumulated; if not, they are ejected by the sorting cylinder. The electrical control module achieves logical control of the entire process through photoelectric switches and the control box; the detection main unit and probes are precisely measured through pre-multiple frequencies and flat displays.2A mode for outputting detection signals.

Manual process on the conveyor: Operators manually load and unload materials, while an electronic detection program controls automatic auditory and visual alarms for defective products.
