C-shaped magnetic core grinding system

Abstract

The invention discloses a C-shaped magnetic core grinding system. The C-shaped magnetic core grinding system comprises a horizontally-arranged belt sander, and a pressing device which applies pressure to the lower side is installed above the belt sander. The C-shaped magnetic core grinding system is characterized in that a horizontal detection assembly used for installing a C-shaped magnetic core is arranged between the belt sander and the pressing device, and a digital display leveling instrument is installed on the horizontal detection assembly. According to the C-shaped magnetic core grinding system, the numerical value of the levelness can be displayed in real time during grinding operation of the belt sander, and an operator is reminded to correct a pressure technique or replace a horizontal plate in time.

[0002] The toroidal core or rectangular core is divided into two C-shaped cores after being cut. When we reassemble the halved C-shaped magnetic core, the ideal state is to need a perfect and seamless fit. When reassembled into a whole, there will inevitably be air on the joint surface. Gaps and dislocations, although high-precision grinding wheel cutting machines are used in the industry at present, the resin cutting discs inevitably swing under high-speed operation, and the temperature of the grinding wheel resin discs will rise during the cutting process, making their strength weak. , so as to increase the swing range, resulting in insufficient flatness of the magnetic core, large air gap after the magnetic core is matched, etc. These problems will cause the inductance value to be low after the magnetic core is combined, so we need to grind the cut surface of the transformer after cutting to improve The inductance value after the magnetic core combination, so as to meet the requirements of technical standards

[0003] At present, magnetic cores made of iron-based nanocrystalline or iron-based amorphous are ground using a flat belt machine, but in the process of mass production and use, because the belt has been running at high speed under high tension, and the position of the product grinding is always There is pressure, long-term high pressure or uneven pressure and high-speed operation will cause the plane position of the flat belt machine to be easily worn and deformed into grooves, which reduces the service life of the plane of the flat belt machine. Once deformed, the grinding out The end face of the product will have insufficient flatness, resulting in an increase in the assembly air gap and unqualified magnetic core performance
