In terms of the formed pressing tonnage, a press of about 100T can meet the requirements, but as far as the charging height is concerned, a press of more than 200T is required to meet the requirements of this charging height, and the value of a press of more than 200T is 200 More than 10,000 yuan, the investment cost is very high, and there are few products that require such a high loading height, so the equipment utilization rate of the 200T press is low, which is not cost-effective economically, so the production of this magnetic core encounters a bottleneck

Embodiment Construction
[0017] For the defects in the background technology, if the thickness of the L83 magnetic core is halved, it can be pressed using a 60-100T press in the prior art. Based on the above analysis, the present invention proposes a processing method of a magnetic core. According to the thickness requirements of the L83 magnetic core, two magnetic cores are sintered, and the two magnetic cores are firmly bonded together. The bonding seam is parallel to the magnetic field lines. In order to meet the thickness requirements of the L83 magnetic core, and without any adverse effects on the magnetic properties of the magnetic core.
[0018] A kind of processing method of magnetic core that the present invention proposes, comprises the following steps:
[0019] A) Calculate the thicknesses of the first magnetic core and the second magnetic core according to the thickness of the target magnetic core; preferably, the thicknesses of the first magnetic core and the second magnetic core are equa...

The invention discloses a machining method of a magnetic core. The machining method comprises the following steps of: A) figuring out thicknesses of a first magnetic core and a second magnetic core according to the thickness of a target magnetic core; B) making the first magnetic core with the corresponding thickness and the second magnetic core with the corresponding thickness according to the thicknesses of the first magnetic core and the second magnetic core; and C) fixedly connecting the first magnetic core with the second magnetic core, wherein a connection joint of the first magnetic core and the second magnetic core is parallel to a magnetic line; and the thickness of the first magnetic core and the second magnetic core which are fixedly connected with each other is not less than the thickness of the target magnetic core. According to the invention, the first magnetic core and the second magnetic core are bonded together to form the target magnetic core so that relevant equipment in the prior art can satisfy the material loading height requirements of the first magnetic core and the second magnetic core and high cost and low utilization rate of the special equipment are avoided; moreover, stable performance is obtained by bonding the first magnetic core and the second magnetic core together to form the target magnetic core.
Description
technical field [0001] The invention relates to the technical field of magnetic core processing, in particular to a processing method of a magnetic core. Background technique [0002] In the prior art, the thickness of the L83 magnetic core is relatively thick, the thickness of the product can reach 90 mm, and the charging height can reach more than 200 mm. In terms of the formed pressing tonnage, a press of about 100T can meet the requirements, but as far as the charging height is concerned, a press of more than 200T is required to meet the requirements of this charging height, and the value of a press of more than 200T is 200 More than 10,000 yuan, the investment cost is very high, and there are few products that require such a high loading height, so the equipment utilization rate of the 200T press is low, which is not cost-effective economically, so the production of this magnetic core encounters a bottleneck . On the other hand, the magnetic core is suitable for solar...
