Detailed Description

As shown in fig. 1 to 6, a magnetic core shaping pressfitting auxiliary member, it adopts brand-new structural design, can cooperate circular magnetic core tip position to carry out the pressfitting processing when using, can ensure that magnetic core tip position has accurate combination groove, can cooperate the reinforcement protective cover to carry out built-up connection in the later stage, the whole security when having ensured magnetic core later stage production, the life-span of magnetic core is longer when using, and structural strength is higher. It includes that the center pin is the cylindrical main part cooperation of upper and lower direction and stabilizes post 1, be equipped with circumference evenly distributed's cylindrical built-up connection fastening screw post 2 on the up end of post 1 is stabilized in the main part cooperation, can carry out holistic fixed connection through this position, cooperate with the mount and be in the same place. The lower end of the main body matching stabilizing column 1 is provided with an integrally formed inverted cone-shaped first forming pressing column 3 which is a main body matching structure for pressing and forming with the end position of the magnetic core. The lower end position of the first forming press-fit column 3 is provided with a cylindrical center combination accurate positioning hole 5 which completely penetrates through the upper end face of a part, and the cylindrical center combination accurate positioning hole can be matched with a positioning column in the hollow position of a magnetic core during processing, so that the placing precision is guaranteed. Two groups of press-fit safe matching grooves 4 are arranged at corresponding positions of the upper end of the first forming press-fit column 3, and the positions are matched with a forming press-fit mold for pressing, so that enough pressure is provided for the forming process.

Preferably, the thickness of the first molded press-fit post 3 in the vertical direction is 2 times the thickness of the body fitting stabilizing post 1 in the vertical direction, the integral structure strength is better, and the service life is longer in the using process.

Preferably, the lower end edge position of the center combination accurate positioning hole 5 is provided with a safe matching fillet structure, so that the safety of the lower end edge position is better, the lower end edge position has a guiding effect when being matched with the structure at the hollow position of the magnetic core, and the smoothness is better when being placed and matched.

Preferably, the projection of the combined connection fastening threaded column 2 in the vertical direction is positioned outside the projection area of the first molding press-fit column 3 in the vertical direction, so that the strength of the fastening position is better in use, the space of the main body press-fit position is larger, and the stability in molding processing is more reliable.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications or replacements can be made without departing from the principle of the present invention, and these modifications or replacements should also be considered as the protection scope of the present invention.
