Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a limiting mechanism for mechanical processing with high stability. Background Art

[0002] When metal sheets are bent, the bending torque is large, so they often need to be fixed first when processing metal components. Therefore, a metal processing limit device is needed. At present, general limit devices use hard limit fixation to fix metal sheets. For example, metal contacts metal, which causes the surface of the fixed metal sheet to be easily scratched, affecting the appearance of the workpiece. In addition, when fixed, the fixing component cannot fit well with the sheet and has average stability.

[0003] When bending thicker metal sheets at a large angle, the bending point must be limited, otherwise the bending position will be offset, and in severe cases, the metal will break or crack, affecting the service life of the bent metal and the bending success rate. Existing processing limit devices, such as the metal processing limit device with patent number CN202320778577.X, lack limit on the metal bending point, and most of the existing devices use flat clamping limiters, which have excessive friction. When the processed metal needs to be processed continuously and progressively, it is necessary to loosen and then clamp again, which is cumbersome. Utility Model Content
