Problems solved by technology

After the amorphous strip or nanocrystalline strip is wound on the level winding machine, the magnetic ring obtained from the winding needs to be taken out of the mold of the level winding machine and sent to the heat treatment process for treatment. However, considering the shrinkage of the product tension The problem is that the inner diameter of the existing heat treatment mold is generally smaller than the inner diameter of the magnetic ring, which leads to the phenomenon that the magnetic core after winding and demolding is prone to curling and warping
Especially for some products made of thin strips, this phenomenon is particularly serious. The inner circle size of the magnetic ring after heat treatment is often too large to fit into the protective box. It is necessary to manually peel the magnetic ring, which greatly increases labor costs and reduces Product production efficiency and product qualification rate

Abstract

The invention discloses a winding mold core. The winding mold core comprises an inner mold and a core mold, the inner mold comprises a main module for winding a strip, the main module is of an annular structure, and a bearing block for bearing a magnetic ring is arranged on the peripheral side of the main module; the core mold is sleeved with the main mold block and attached to the inner circumferential side of the main mold block, and a positioning structure for fixing the mutual position is arranged between the core mold and the main mold block. A winding installation block used for being connected with a winding machine is arranged on at least one end face of the core mold in the axial direction of the main module. The winding mold core has the advantages of being simple in structure, convenient to assemble, and capable of effectively overcoming the bad conditions that after a large magnetic core is wound, a magnetic ring is scattered and warped inwards due to winding tension after demolding and the like.

Description

technical field [0001] The invention relates to the field of magnetic ring processing, in particular to a winding mold core. Background technique [0002] At present, large-scale amorphous magnetic rings or nanocrystalline magnetic rings are wound by level winders. After the amorphous strip or nanocrystalline strip is wound on the level winding machine, the magnetic ring obtained from the winding needs to be taken out of the mold of the level winding machine and sent to the heat treatment process for treatment. However, considering the shrinkage of the product tension The problem is that the inner diameter of the existing heat treatment mold is generally smaller than the inner diameter of the magnetic ring, which leads to the curling and warping of the magnetic core after winding and demoulding. Especially for some products made of thin strips, this phenomenon is particularly serious. The inner circle size of the magnetic ring after heat treatment is often too large to fit ...
