Fire-fighting air pipe nip machine

Abstract

A fire-fighting air pipe nip machine comprises a nip module, the nip module comprises a nip rotating base, the nip rotating base is assembled with a first nip base through a nip mounting base, the first nip base is hinged to nip hinge plates through nip base shafts, the nip hinge plates are mounted at one ends of second nip bases, and a nip hinge block is further mounted on each second nip base; the nip hinge blocks are hinged to one end of a nip hinge head through first nip rotating shafts, the other end of the nip hinge head is installed on nip telescopic shafts, the nip telescopic shafts are installed in nip oil cylinders, and the ends, away from the nip telescopic shafts, of the nip oil cylinders are hinged to the nip rotating base through second nip rotating shafts; a plurality of nipcomponents are respectively mounted on the first nip base and the second nip bases and are distributed in the circumferential directions of the first nip base and the second nip bases; and a hemmingwheel is installed on each nip component, and the hemming wheels are used for extruding first connecting discs so as to achieve hemming meshing of the first connecting discs towards second connectingplates.

Description

technical field [0001] The invention relates to a fire-fighting air duct connection technology, in particular to a fire-fighting air duct bite machine. Background technique [0002] In the process of installing the fire-fighting air duct, two fire-fighting air ducts need to be connected together. Flange connection is generally used for fire-fighting air ducts with larger diameters, that is, flanges are installed at the ends of the two fire-fighting air ducts, and finally through Flanges and bolts (screws) connect the two sections for fire protection. For fire-fighting air ducts that are directly too small, direct installation of flanges will result in high costs and will weaken the strength of the connection end. Therefore, a bite connection is generally used. The first connection plate 311 and the second connection plate 321 are respectively arranged at the pipe joints (see image 3 ), and then one of the first connecting plate 311 and the second connecting plate 321 is cr...

Problems solved by technology

[0003] However, the current biting machine is designed for the connection of branch pipes, and there will be a large number of bends in the actual installation process. When processing the bends, it is relatively difficult to clamp them because the two fire-fighting air pipes are not in the same axis. , so at present, artificial bite is still used when connecting the elbow, that is, the first connecting plate 311 is hit with a hammer, so that the first connecting plate 311 is curled and occluded to the second connecting plate 321

This method will first cause extremely poor sealing performance, and the bite will be uneven, and the strength of the connection will also be affected. Ultimately, the efficiency is extremely low, and quality control is extremely difficult.
