They are a kind of building material with excellent performance and wide application. Among them, the corner rock wool sandwich panel is an integrated rock wool sandwich panel with a 90° bend, which is installed at the corner of the building wall.

[0003] In the prior art, when processing the corner rock wool sandwich panel, a V-shaped groove is first opened on the end surface of the rock wool sandwich panel by a cutting device, and then the rock wool sandwich panel is bent along the V-shaped groove by a bending device. However, the traditional bending device cannot center the V-shaped groove on the end surface of the rock wool sandwich panel, and it is necessary to manually use auxiliary tooling to center the V-shaped groove on the rock wool sandwich panel with the processing center of the bending device, which takes a long processing time, has low processing efficiency, poor processing consistency, and cannot achieve fully automatic production.
