Technical Field

[0001] The utility model relates to the technical field of civil air defense door production, in particular to a channel steel cutting and grooving device for civil air defense door production. Background Art

[0002] Civil defense doors are civil defense protection equipment, that is, the doors at the entrances and exits of people's defense projects. They have a simple structure and are classified in many ways according to installation styles or functions. In the production of civil defense doors, channel steel is an indispensable material. The so-called channel steel is a long strip of steel with a grooved cross-section, which is carbon structural steel.

[0003] Since the production of civil air defense doors does not require overly long channel steels, they usually have to be cut during production. The current manual cutting method is not only inaccurate but also inefficient. When cutting equipment is used, batch cutting cannot be achieved, which does not significantly improve production efficiency. Utility Model Content

A plurality of groups of bidirectional threads are opened on the rotating shaft, and each group of clamping plates consists of two. The two-way threads are symmetrically installed, and the side walls of the clamping plates are in contact with the inner walls of the longitudinal grooves. After placing a plurality of channel steels on the side plates, the clamping plates are pressed against the bottom surface of the groove of the channel steels under the descending action of the I-shaped frame, and then the rotating shaft is rotated manually.
