Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to a trimming device for processing a motor iron core. Background Art

[0002] The existing motor core is generally composed of multiple cut silicon steel sheets stacked together, and the silicon steel sheets need to be cut during processing. Specifically, in the process of rolling and shearing the silicon steel sheets, the silicon steel sheet longitudinal shearing line equipment cuts the silicon steel sheet roll with a width of 150 to 1250 mm and a thickness of 0.23 to 0.3 mm into strips of varying widths. In order to ensure that the edge burrs and straightness of the strips meet the requirements, a 5 mm wide edge material needs to be cut off on one side of the silicon steel sheet roll, and a 5 to 40 mm edge material will be left on the other side due to different discharge specifications. When processing these edge materials, a waste trough is usually set under the shearing machine, and the excess silicon steel strips are introduced into the waste trough by using a baffle. However, this processing method has problems, because the entire edge material is directly introduced into the waste trough without being broken, resulting in irregular stacking of the edge material in the waste trough, which is easy to overflow and does not fully utilize the space of the waste trough. For this reason, we propose a trimming device for motor core processing. Utility Model Content
