Products Description
The DT4C AC Relay Iron Core CNC Lathe Processing is a key magnetic circuit component used in AC industrial control relays. It is manufactured through CNC turning and precision forming processes. This type of iron core typically features structural slots and is riveted together with stamped copper parts to form a stable magnetic circuit and electrical connection structure. During the operation of the AC relay, the iron core plays a crucial role in magnetic flux conduction, action response, and structural support; therefore, it requires extremely high material purity, dimensional accuracy, and processing stability.
Core Material Performance and Advantages
Material Selection
Manufactured for AC Core for Industrial Relay using high-performance YG15 tungsten carbide. YG15 is renowned for its extremely high hardness (HRA90) and wear resistance, enabling long-term stable operation in electromagnetic environments with high magnetic flux density and high frequency, and is less prone to magnetic fatigue.
Magnetic Properties
The slotted structure design for AC Core Riveted with Copper Terminal (such as E-shaped, EI-shaped, or specially segmented slots) effectively reduces the leakage magnetic induction of the iron core and reduces eddy current losses in the magnetic lines of force, thereby improving the electromagnetic efficiency of the relay.
Structural Characteristics
Pure Iron Core for AC Relay combined with riveted copper stamping, it achieves an optimal balance between high current carrying capacity and low resistance.
Production Process and Flow
Precision Turning
YG15 tungsten steel for
AC Core Riveted with Copper Terminal is rough-turned using a high-rigidity CNC lathe to remove most of the excess material and form the initial outline.
Cold Heading
The dividing grooves are stamped using a "one-die, three-punch" process. This process is performed at room temperature to avoid deformation and internal stress caused by heating for Pure Iron Core for AC Relay.
Heat Treatment and Demagnetization
After forming, specific heat treatment is performed, followed by demagnetization to ensure the material's hardness reaches HRA90 and eliminate residual magnetism.
Surface Finishing and Assembly
The groove openings are deburred, with the surface roughness controlled to Ra≤0.8μm. The riveted copper stamped parts are then assembled for AC Relay Core and Copper Ring.
Design of Riveting Structure for Copper Components
Short-Circuit Ring Carrier: Grooves are provided on the copper component for mounting the short-circuit ring (magnetic ring), eliminating vibration and noise during AC engagement for AC Core for Industrial Relay.
Electrical Connection Point: The copper component connects to the lead-out terminals of the coil frame, forming a complete current loop for AC Core Riveted with Copper Terminal.
