Description
Technical Field
[0001] The utility model belongs to the technical field of iron core processing, in particular to a hot press for processing stator iron cores. Background Art
[0002] The stator core is an important component of the motor stator and the main component of the motor magnetic circuit. The stator core is mainly formed by pressing silicon steel sheets and gear plates and other parts into a whole through a hot press.
[0003] A hot press is usually required for hot pressing of the stator core during processing. When using the existing hot press, the stator core is usually placed directly in the hot pressing mold. After the hot pressing is completed, the stator core is not easy to be taken out by the staff due to the high heat. Directly taking it out may easily burn the staff, so it is necessary to wait for the stator core to cool down before taking it out, which consumes a lot of time and reduces work efficiency. Therefore, we propose a hot press for stator core processing. Utility Model Content
[0004] The purpose of the utility model is to provide a hot press machine for processing stator cores. By setting a rotating component, specifically by rotating a turntable, the hot-pressed core leaves the position of the hot-pressing mold, and the unhot-pressed core moves to just below the hot-pressing mold. This reciprocating motion allows the hot-pressed core to be cooled without stopping work. During the rotation of the turntable, the staff can place the empty mold on the right side to replenish the core, thereby achieving continuous hot pressing. This solves the problem that the hot-pressed core can be easily scalded by the staff if it is directly taken out, so that it is necessary to wait for the stator core to cool before taking it out, which consumes a lot of time and reduces work efficiency.

[0036] When in use, the iron cores are placed in the several placement molds 123 on the back and right side in turn, and the several placement molds 123 on the front and left sides do not place the iron cores. After the placement is completed, the staff operates the controller 11, and the hydraulic cylinder 111 starts to drive the lifting plate 113 to move downward, and the lifting plate 113 slides on the stabilizing rod 115, and the hot pressing mold 114 moves together. When the hot pressing mold 114 is plugged into the placement mold 123 directly below, the internal iron core is hot pressed. After the hot pressing is completed, the hot pressing mold 114 is driven to reset upward, and the motor When 141 is started, the gear 142 is driven to rotate counterclockwise by 60 degrees, and the gear 142 drives the turntable 121 to rotate clockwise by 60 degrees through the gear ring 122, so that the hot-pressed iron core leaves the position of the hot-pressing mold 114, and the unhot-pressed iron core moves to the bottom of the hot-pressing mold 114.

The limiting ring 152 will limit the push shaft 151. At the same time, the push shaft 151 will push the vertical rod 232 moved to the front upward, and the limiting ring 1 233 will move together and squeeze the spring 234. At the same time, the vertical rod 232 will drive the push plate 231 to move upward, and the iron core placed inside the mold 123 will be ejected, which is convenient for the staff. The work efficiency can be improved by taking it quickly. The rotation of the turntable 121 will make the protrusion 222 leave the arc-shaped inclined block 153, and the push shaft 151 will reset downward by its own gravity, and the arc-shaped inclined block 153 will also reset accordingly.
