Description

Technical Field

[0001] The utility model relates to the technical field of edge grinding mechanisms, and more specifically, to a double-station stainless steel sheet edge grinding mechanism. Background Art

[0002] When producing stainless steel sheets, due to the extrusion of the upper and lower dies of the mold on the sheet material, the stainless steel sheets are blanked from the sheet material, resulting in blanking edges on the back of the edge of the stainless steel sheet where it is extruded by the cutting edge. These blanking edges will affect the subsequent stretching process, making it possible for the stamped parts to have wire drawing and stamping damage phenomena, and will also damage the tools for the stretching process, shortening the service life of the mold. Therefore, it is necessary to polish the surface of the stainless steel sheet. When the existing full-automatic edge grinding of stainless steel sheets is carried out, generally manual assistance is required to place the stainless steel sheets, so the grinding efficiency of the stainless steel sheets is low. Therefore, an edge grinding mechanism for stainless steel sheets that can automatically grind is needed.

[0003] In the existing technology, as disclosed in the document with the publication number CN218639266U, a double-station stainless steel sheet edge grinding mechanism is specifically disclosed. Although the device in this document can perform edge grinding on stainless steel sheets, this processing can only be carried out on the segmented block-shaped stainless steel sheets and cannot perform edge grinding on continuous strip-shaped stainless steel. For this reason, we propose a double-station stainless steel sheet edge grinding mechanism. Summary of the Utility Model
