Specifically, firstly, the to-be-removed part 10 is mounted on the material bearing plate 4, after the to-be-removed part 10 on the material bearing plate 4 is processed by a processing device, an external inflating device inflates gas into the expansion part 2, the expansion part 2 expands and drives the material ejecting part 31 to move along the first through hole 41 through the material removing plate 3 until the material ejecting part 31 extends out of the first through hole 41 and carries the to-be-removed part 10 away from the material bearing plate 4, and thus the processed to-be-removed part 10 can be removed from the material bearing plate 4; after the processed to-be-stripped part 10 is taken down from the material bearing plate 4, an external air charging device sucks air into the expansion part 2, the expansion part 2 drives the material ejecting part 31 to move downwards and form the first through hole 41, and then a new to-be-stripped part 10 can be installed on the material bearing plate 4.
In the invention, the stripper plate 3 is provided with a material ejecting part 31, and the material bearing plate 4 is provided with a first through hole 41; the stripper plate 3 is arranged on the end surface of the material bearing plate 4 far away from the piece to be stripped 10; the material bearing plate 4 and the expansion piece 2 are both fixedly connected to the material removing fixing disc 1; the expansion piece 2 is connected with the stripper plate 3, and the expansion piece 2 is used for driving the ejection piece 31 on the stripper plate 3 to slide along the first through hole 41 during inflation so as to drive the piece to be stripped 10 to be away from the material bearing plate 4. The stripping structure can be arranged on a workbench of processing equipment, the processing equipment can directly process the piece to be stripped 10 on the material bearing plate 4, and through holes and the like are processed on the piece to be stripped 10, so that the damage to the workbench when the piece to be stripped 10 is processed is avoided, and the manufacturing difficulty of the piece to be stripped 10 is reduced; the part 10 to be stripped is directly machined on the material bearing plate 4, a light honeycomb is not needed to be used as a workbench, and the manufacturing difficulty of the machining platform is further reduced; in addition, through the design of the stripping mechanism, the to-be-stripped part 10 can be conveniently taken down from the material bearing plate 4, the damage to the to-be-stripped part 10 during manual workpiece taking is avoided, and the processing quality of the to-be-stripped part 10 is improved.
