Description

Technical Field

[0001] The utility model relates to the field of iron core detection devices, and more specifically, to an iron core limiting mechanism. Background Technique

[0002] Common transformer iron cores are generally made of silicon steel sheets. Silicon steel is a kind of steel containing silicon, and its silicon content is 0.8 - 4.8%. Using silicon steel as the iron core of a transformer is because silicon steel itself is a magnetic substance with strong magnetic conductivity. In an energized coil, it can generate a relatively large magnetic induction intensity, thereby enabling the volume of the transformer to be reduced. After the iron core is manufactured, it needs to be subjected to pressure testing.

[0003] The patent with the application number 202221743915.8 discloses a pressure - applying device for testing the strength of ferrite cores. This device can be rotated by an electric motor to drive a moving part to move downward along a transmission lead screw, thereby driving a strength tester to move vertically. The testing head is used to squeeze the ferrite core product placed on the testing plane downward, and after the test is completed, the moving part is driven upward by the electric motor to disengage from the ferrite core to complete the test. This utility model can achieve the purpose of accurately applying pressure by controlling the electric motor, and can control the magnitude of the applied pressure more evenly and balancedly, thereby improving the test accuracy.
