Description
Technical Field
[0001] The utility model relates to the field of blanking suction cups, in particular to a blanking suction cup for blanking of numerical control machine tools. Background Art
[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. At present, when CNC machine tools are processing plates, they need to use a blanking device to unload the plates. The traditional unloading devices include hydraulic and pneumatic unloading, magnetic unloading, and robot unloading. The unloading of plates is mainly hydraulic and pneumatic unloading, and the hydraulic and pneumatic unloading devices are mostly in the form of unloading suction cups.
[0003] At present, there are still some problems in the use of suction cups for material discharge. For example, after the traditional suction cups for material discharge come into contact with the plate, in order to ensure the tightness of the contact between the suction cups and the plate, the suction cups and the plate are compacted. However, the lack of a buffer structure may easily cause the suction cups and the plate to come into contact too violently, resulting in certain damage to the plate or the suction cups. At the same time, the traditional suction cups are mounted on suction cup racks, and the traditional suction cup racks have a fixed structure. After the suction cups are mounted on the suction cup racks, their positions are fixed and cannot be adjusted. Therefore, they cannot be used for adsorption of plates of different sizes and shapes, and their applicability is poor. Utility Model Content
