Product Description

Introduction:




This system is available for

1. This system is available for automatic hardness separation of iron casting, nodular cast iron, wear resisting cast iron and malleable cast iron (commonly known as malleable iron), hardness measurement of all kinds of iron casting after normalizing, annealing, quenching and tempering.

2. Hardness measurement and separation of any normalizing and annealing steel, such as all kinds of thread rolling parts, gear, etc. 

3. Hardness separation of plumbing pipe fittings.

Principle:

Hardness separation is mainly based on the electromagnetic induction impedance plane analysis, separation probe is composed by AC primary coil and secondary coil, when placing the workpiece in the coil, system will induce eddy current in the workpiece according to the electromagnetic principle, the magnetic field generated from eddy current will make the secondary induction coil induced the changes of voltage, namely, the change of probe impedance. Through the analysis of the change, operator can learn the variation of a thermal physical property of the workpiece, such as hardness, size, material composition and so on.

Equipment:

This EHS-1X Automatic Eddy Current Hardness Testing Sorting Machine is composed of hardness instrument, detection coil, mechanical transmission and automatic separation, the instrument adopted vehicle wiring, installed with imported components, with features of stable and reliable performance, and high sensitivity, incentive power regulation, sensitivity adjustment, phase adjustment, impedance balance adjustment, qualified and unqualified count, and other functions are set on instrument panel. Using fluorescent oscilloscope tube for display. Two detection coils, one standard coil is used for holding qualified products, the other one is used for detecting the hardness of workpiece. Mechanical transmission parts are composed by color nonmagnetic materials, avoid the influence of other magnetic materials on detection coil. Automatic separating part adopts pneumatic way to driving the movement of baffle.


Features:


1. Instrument has excitation frequency, phase adjustable, can adapt to hardness separation of all kinds of magnetic metal parts .

2. Impedance analysis can restrain the influence of other physical factors on the hardness measurement.

3. Using two detection coils, the stability of the system is improved.

4. Automatic counting can directly get the total number of nonconforming products.


Parameters:



1. Detection objects: hardness separation of all kinds of magnetic material (steel, iron) of parts.

2. Excitation frequency: various.

3. Exciting power: 0~110W.

4. Amplifier gain: 0~70db.

5.Display mode: Square fluorescence oscilloscope tube.

6. Detection speed:2500~3500p/h. 

7. Physical dimension: can be customized according to actual needs.
