Problems solved by technology

Therefore, during the sintering process, the magnetic core is often prone to glue removal and cracking, which seriously affects the product quality and brings unnecessary economic losses to the manufacturer.
[0004] The main reason for the above degumming and cracking is that during the sintering process, the heat distribution in the kiln body is uneven, the distribution of the magnetic core is uneven, and the degumming effect is poor, resulting in poor consistency of the sintered magnetic core. At the same time, The heat loss of the bell kiln body is serious, and there are potential safety hazards in production

Abstract

The invention discloses large-size magnetic core glue removal sintering equipment, and belongs to the technical field of magnetic core machining. The problems that distribution of heat in sintering equipment is uneven, the glue removal effect is poor, and sintered magnetic cores are poor in consistency are solved. The large-size magnetic core glue removal sintering equipment is characterized by comprising a sintering kiln body, sintering bases, high-temperature air feeding plates, a high-temperature thermal cycling fan and a return pipe. The invention further discloses a manufacturing method of the large-size magnetic core glue removal sintering equipment. By arranging return material slide grooves and the sintering bases, large-size magnetic cores can be separated to be placed conveniently, the high-temperature air feeding plates are installed between the return material slide grooves, high-temperature hot air is sprayed out through gas spraying holes of the high-temperature air feeding plates and conducts glue removal sintering treatment on the magnetic cores placed on the sintering bases after being heated by a heater and a metal net plate, through cooperation of the high-temperature thermal cycling fan and a return duct, hot air flows cyclically, glue volatilization is facilitated, the glue removal time is short, and the efficiency is high.
