[0003] The rotor core demagnetization steel tooling of this patent can cooperate with a press to demagnetize the rotor core. It is simple to operate, efficient, and has a low magnetic steel breakage rate. However, one or more protruding structures of the exit upper pressure plate and the loose upper pressure plate in this patent may be broken and damaged during actual long-term use, resulting in the entire exit upper pressure plate or the loose upper pressure plate being scrapped and unusable. The entire exit upper pressure plate or the loose upper pressure plate needs to be replaced, which increases the tooling cost. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A detachable demagnetized steel tooling includes a pressing plate and a plurality of push heads, wherein the pressing plate is provided with a plurality of penetrating mounting holes, the push heads include a connecting seat and a push column, a threaded hole is provided at the bottom of the connecting seat, a mounting bolt is provided in the mounting hole, and the mounting bolt passes through the mounting hole and extends into the threaded hole to realize a detachable connection between the pressing plate and the connecting seat.

[0007] Furthermore, a positioning column is arranged at the center of the pressing plate.

[0008] Furthermore, a first sinking groove is arranged at the top of the pressing plate at a plurality of mounting holes, and the bottom of the connecting seat extends into the first sinking groove.

[0009] Furthermore, a second recessed groove is provided at the bottom of the pressure plate at a plurality of mounting holes, and the bolt head of the mounting bolt is located in the second recessed groove.

[0010] Furthermore, the mounting bolt is a hexagon socket bolt.

[0011] Furthermore, the size of the connecting seat is larger than the size of the push column.

[0012] Furthermore, the top of the push column is provided with a chamfer.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The detachable demagnetizing steel tooling of the utility model realizes a detachable connection by connecting a pressing plate and a plurality of push heads through mounting bolts. Therefore, when one or more push heads are bent or damaged, the damaged push heads can be removed and replaced separately without causing the entire demagnetizing steel tooling to be scrapped. This can effectively reduce the cost of repair and maintenance, and the removal and replacement of the repair is simple.

[0015] At the same time, by setting the push head to a structural form including a connecting seat and a push column, and the size of the connecting seat is larger than the size of the push column, it is possible to ensure the connection strength between the push head and the pressure plate, and shorten the length of the push column, thereby solving the problem of insufficient strength caused by the existing push column length process and improving the service life of the push column. In actual use, the push column only needs to loosen the magnet and push most of the position out of the rotor. BRIEF DESCRIPTION OF THE DRAWINGS
