Description

Technical Field

[0001] The utility model belongs to the technical field of medium frequency furnace yokes, and more specifically relates to a medium frequency furnace yoke installation structure. Background Art

[0002] A medium frequency furnace is a power supply device that converts industrial frequency 50-2000HZ alternating current into medium frequency. A magnetic yoke is generally provided inside the medium frequency furnace. The magnetic yoke is a yoke iron made of stacked silicon steel sheets. It is evenly and symmetrically distributed around the induction coil. It plays a role in restraining the outward diffusion of the leakage magnetic field of the induction coil and also plays a certain role in fixing the induction coil. The magnetic yoke is usually connected to the outside of the induction coil by abutting screws.

[0003] However, the abutment screw does not limit the horizontal displacement of the yoke when it abuts the yoke. As the intermediate frequency furnace operates, the yoke may shift horizontally, affecting the yoke's magnetic shielding effect and causing heat and damage to the outer structure of the intermediate frequency furnace. Therefore, in view of this, the existing structure and its shortcomings are studied and improved to provide a yoke mounting structure for an intermediate frequency furnace, in order to achieve a more practical and valuable purpose.

[0014] The utility model can realize the flexible movement of the slider and the limit plate through the cooperation of the bidirectional screw and the connecting seat, and make the limit plate self-locking after movement, thereby limiting the horizontal position of the yoke. The yoke will deviate during the long-term operation of the medium frequency furnace, thereby increasing the stability of the product during operation.

[0015] The utility model can drive the pressure rod and the limit seat on the pressure rod to press the limit seat on the bidirectional screw rod through the cooperation of the fixing tube, the spring and the connecting plate, so as to prevent the bidirectional screw rod from rotating due to the vibration generated during the operation of the medium frequency furnace.
