Description

Slotted fast lap joint longitudinal magnetic furnace frame and longitudinal magnetic heat treatment method thereof Technical Field The invention relates to the technical field of a longitudinal magnetic furnace frame, in particular to a slotted quick-lap longitudinal magnetic furnace frame and a longitudinal magnetic heat treatment method thereof. Background The longitudinal magnetic heat treatment is one of key processes for improving the performance of soft magnetic materials, and magnetic domain orientation can be effectively regulated and controlled by applying a magnetic field along the axial direction of the materials and performing heat treatment, so that the loss of a magnetic core is reduced, and the magnetic permeability is improved. The process is widely applied to the final heat treatment links of various high-performance magnetic cores. In the longitudinal magnetic heat treatment process, the magnetic core product is usually heated and cooled in a manner of being hung on a rod, so that the magnetic field direction is consistent with the magnetic core axial direction, and deformation caused by dead weight or improper support is avoided. The conventional furnace frame of the longitudinal magnetic furnace mostly adopts a porous plate equipped with a bolt fixing structure, and has the problems of low installation efficiency, low universality and the like. Especially when different sizes are produced in small batches, the traditional furnace frame is difficult to adjust, and quick assembly and taking of the magnetic cores are difficult to realize. In addition, the furnace frame may be slightly deformed due to thermal stress during the heat treatment process, so that the heating uniformity of the magnetic core is affected, and finally, the performance of the magnetic core is reduced. Therefore, a longitudinal magnetic furnace frame with simple structure, convenient assembly and disassembly and wide adaptability is needed. Disclosure of Invention The invention aims to provide a slotted quick-lap longitudinal magnetic furnace frame and a longitudinal magnetic heat treatment method thereof, so as to meet the requirements of a high-performance and high-efficiency longitudinal magnetic heat treatment process. In order to solve the technical problems, the technical scheme includes that the slotted fast-lap longitudinal magnetic furnace frame comprises a first fixing plate, a second fixing plate, supporting conducting rods, an input conducting rod and an output conducting rod, wherein a plurality of first slots are formed in the first fixing plate, a plurality of second slots corresponding to the first slots one by one are formed in the second fixing plate, the supporting conducting rods are used for placing magnetic cores, each supporting conducting rod simultaneously penetrates through one of the first slots and one of the second slots which are correspondingly arranged, one end of each supporting conducting rod is connected to the input conducting rod or the output conducting rod in series or in parallel through a first copper bar, and the other end of each supporting conducting rod is correspondingly connected to the first fixing plate in series or in parallel through a second copper bar. The number of the supporting conducting rods, the placement of the supporting conducting rods on the furnace frame and the connection mode of the loops can be flexibly selected according to actual production requirements. The invention is used as a special longitudinal magnetic furnace frame, which can avoid uneven heating and part damage caused by the problems of poor contact, split flow and the like in the current conduction process, simplify the assembly process of the longitudinal magnetic furnace frame, reduce redundant pretreatment steps such as insulation, fixation and the like, and reduce the production and assembly cost of equipment. According to the invention, the support conducting rods are sleeved in the ceramic gaskets corresponding to the first groove or the second groove, current splitting is avoided through the insulation effect of the ceramic gaskets, the support conducting rods can directly penetrate through the magnetic cores and then are sleeved in the ceramic gaskets, then are integrally placed in the first groove and the second groove, a perforation type assembly mode of a traditional furnace frame is not needed, namely one end of each conducting rod does not need to penetrate into a furnace frame hole site first, then the magnetic cores are sleeved, and finally the other end of each conducting rod penetrates into the corresponding furnace frame hole site, and the support conducting rods can be flexibly connected in a serial or parallel mode according to the current required by each conducting rod, so that the mass production operation efficiency of the furnace frame is improved. As a further aspect of the present invention, the first groove and the second groove are arranged in a central symmetry
