Automatic shaft hardness material sorting machine

Automatic shaft hardness material sorting machine

  • Classification:Automatic axial eddy current flaw detector
  • Number of visits:second
  • Date of issue:2021-04-24 10:12:49
  • Product overview

Main technical performance of the equipment

1, flaw detection sensitivity: from the workpiece surface to the metal extension depth ≥0.06mm, length ≥2mm crack, defect; For the crack inside the metal has not yet extended to the surface of the workpiece, when the metal thickness between the upper edge of the crack and the surface of the workpiece is ≤0.2mm, the crack depth ≥0.2mm, length ≥2mm can be detected

2. Leakage rate: 0%, that is, 99.99% of unqualified products are removed; Misjudgment rate ≤2%, all rejected products can be re-inspected once, to reduce misjudgment

3. Probe: the point differential probe is used to scan the workpiece to be detected

4, Detection frequency range: 100Hz~1MHz, adjustable

5, Band-pass filtering, center frequency 250~1000KHz, 8 levels

6. Gain: Gain of each channel is 0~60dB, adjustment amount is 1dB/ gear

7, phase: 0°~360°, step distance is 1°

Hardness sorting principle: because the hardness value of magnetic conductive materials, material varieties, hardening layer depth, heat treatment state, parts of the defects (such as cracks, pores, inclusion, etc.) have different effects on the magnetic field, and there is a certain corresponding relationship. When the measured workpiece is in contact with the uniformly distributed probe magnetic field, the amount of magnetic field in the probe changes, the probe coil produces an exciting current, and is transmitted to the instrument through the wire. After the analysis and processing of the instrument's central circuit, the quality of the measured workpiece can be automatically discriminated through computer software processing and displayed on the display screen. It is with the help of the measured workpiece magnetic flux caused by the change of the electromagnetic effect of the electrical signal, after amplification and conversion after computer software processing, to achieve the material composition, hardness, surface hardening layer depth, crack, mixing and other defects detection.

Technical parameters: hardness detection sensitivity: Rockwell: ±2HRC; Vickers: ± 40HV. Range of error: effective separation of different materials
