Description

Technical Field

[0001] The invention relates to the technical field of profile cutting, and in particular to a cutting device and a cutting method for processing fireproof windows. Background Art

[0002] In modern industrial production, profiles are used more and more widely. Profiles need to be cut during use to meet their own needs. When processing fireproof windows, profiles of the same specification and length need to be cut many times. Due to their different structures, the structures of the profiles are also different. In order to assemble different profiles, it is necessary to cut notches of different shapes and angles at the ends of the profiles.

[0003] Referring to the Chinese patent application document with publication number CN107243819A, an aluminum profile cutting machine is disclosed. The aluminum profile to be cut is inserted through the limit block and pushed forward to the slide plate for locking. The aluminum profile to be cut is limited in the horizontal direction by a horizontal positioning mechanism, and the aluminum profile to be cut is limited in the vertical direction by a vertical positioning mechanism. When the aluminum profile to be cut is positioned, the cutting machine installed on the screw slide moves downward to realize the cutting operation of the aluminum profile to be cut. With respect to the above-mentioned related technologies, when cutting and processing the profiles of the fireproof windows, the cut profiles need to be spliced ​​and assembled, so the cut of the profile needs to have a certain angle so that the cut profiles can be assembled into the shape of the fireproof windows. Therefore, when cutting the profiles, it is necessary to make the cutter and the profile have a corresponding angle, and then after cutting the end of the profile, the profile is cut again according to the actual required length, so that the profiles need to be constantly moved and turned over so that the cut profiles can be assembled, resulting in low cutting efficiency. Summary of the invention
